IMPLICATVRA -- in twelve volumes, vol. XI



possibile – “what is actual is not also possible – grave mistake!” – H. P. Grice. compossible, capable of existing or occurring together. E.g., two individuals are compossible provided the existence of one of them is compatible with the existence of the other. In terms of possible worlds, things are compossible provided there is some possible world to which all of them belong; otherwise they are incompossible. Not all possibilities are compossible. E.g., the extinction of life on earth by the year 3000 is possible; so is its continuation until the year 10,000; but since it is impossible that both of these things should happen, they are not compossible. Leibniz held that any non-actualized possibility must be incompossible with what is actual.  possible worlds, alternative worlds in terms of which one may think of possibility. The idea of thinking about possibility in terms of such worlds has played an important part, both in Leibnizian philosophical theology and in the development of modal logic and philosophical reflection about it in recent decades. But there are important differences in the forms the idea has taken, and the uses to which it has been put, in the two contexts. Leibniz used it in his account of creation. In his view God’s mind necessarily and eternally contains the ideas of infinitely many worlds that God could have created, and God has chosen the best of these and made it actual, thus creating it. Similar views are found in the thought of Leibniz’s contemporary, Malebranche. The possible worlds are thus the complete alternatives among which God chose. They are possible at least in the sense that they are logically consistent; whether something more is required in order for them to be coherent as worlds is a difficult question in Leibniz interpretation. They are complete in that they are possible totalities of creatures; each includes a whole possible universe, in its whole spatial extent and its whole temporal history if it is spatially and temporally ordered. The temporal completeness deserves emphasis. If “the world of tomorrow” is “a better world” than “the world of today,” it will still be part of the same “possible world” the actual one; for the actual “world,” in the relevant sense, includes whatever actually has happened or will happen throughout all time. The completeness extends to every detail, so that a milligram’s difference in the weight of the smallest bird would make a different possible world. The completeness of possible worlds may be limited in one way, however. Leibniz speaks of worlds as aggregates of finite things. As alternatives for God’s creation, they may well not be thought of as including God, or at any rate, not every fact about God. For this and other reasons it is not clear that in Leibniz’s thought the possible can be identified with what is true in some possible world, or the necessary with what is true in all possible worlds. That identification is regularly assumed, however, in the recent development of what has become known as possible worlds semantics for modal logic the logic of possibility and necessity, and of other conceptions, e.g. those pertaining to time and to morality, that have turned out to be formally analogous. The basic idea here is that such notions as those of validity, soundness, and completeness can be defined for modal logic in terms of models constructed from sets of alternative “worlds.” Since the late 0s many important results have been obtained by this method, whose best-known exponent is Saul Kripke. Some of the most interesting proofs depend on the idea of a relation of accessibility between worlds in the set. Intuitively, one world is accessible from another if and only if the former is possible in or from the point of view of the latter. Different systems of modal logic are appropriate depending on the properties of this relation e.g., on whether it is or is not reflexive and/or transitive and/or symmetrical. The purely formal results of these methods are well established. The application of possible worlds semantics to conceptions occurring in metaphysically richer discourse is more controversial, however. Some of the controversy is related to debates over the metaphysical reality of various sorts of possibility and necessity. Particularly controversial, and also a focus of much interest, have been attempts to understand modal claims de re, about particular individuals as such e.g., that I could not have been a musical performance, in terms of the identity and nonidentity of individuals in different possible worlds. Similarly, there is debate over the applicability of a related treatment of subjunctive conditionals, developed by Robert Stalnaker and David Lewis, though it is clear that it yields interesting formal results. What is required, on this approach, for the truth of ‘If it were the case that A, then it would be the case that B’, is that, among those possible worlds in which A is true, some world in which B is true be more similar, in the relevant respects, to the actual world than any world in which B is false. One of the most controversial topics is the nature of possible worlds themselves. Mathematical logicians need not be concerned with this; a wide variety of sets of objects, real or fictitious, can be viewed as having the properties required of sets of “worlds” for their purposes. But if metaphysically robust issues of modality e.g., whether there are more possible colors than we ever see are to be understood in terms of possible worlds, the question of the nature of the worlds must be taken seriously. Some philosophers would deny any serious metaphysical role to the notion of possible worlds. At the other extreme, David Lewis has defended a view of possible worlds as concrete totalities, things of the same sort as the whole actual universe, made up of entities like planets, persons, and so forth. On his view, the actuality of the actual world consists only in its being this one, the one that we are in; apart from its relation to us or our linguistic acts, the actual is not metaphysically distinguished from the merely possible. Many philosophers find this result counterintuitive, and the infinity of concrete possible worlds an extravagant ontology; but Lewis argues that his view makes possible attractive reductions of modality both logical and causal, and of such notions as that of a proposition, to more concrete notions. Other philosophers are prepared to say there are non-actual possible worlds, but that they are entities of a quite different sort from the actual concrete universe  sets of propositions, perhaps, or some other type of “abstract” object. Leibniz himself held a view of this kind, thinking of possible worlds as having their being only in God’s mind, as intentional objects of God’s thought. 

post-modern – H. P. Grice plays with the ‘modernists,’ versus the ‘neo-traditionalists.’ Since he sees a neotraditionalist like Strawson (neotraditionalist, like neocon, is a joke) and a modernist like Whitehead as BOTH making the same mistake, it is fair to see Grice as a ‘post-modernist’ -- of or relating to a complex set of reactions to modern philosophy and its presuppositions, as opposed to the kind of agreement on substantive doctrines or philosophical questions that often characterizes a philosophical movement. Although there is little agreement on precisely what the presuppositions of modern philosophy are, and disagreement on which philosophers exemplify these presuppositions, postmodern philosophy typically opposes foundationalism, essentialism, and realism. For Rorty, e.g., the presuppositions to be set aside are foundationalist assumptions shared by the leading sixteenth-, seventeenth-, and eighteenth-century philosophers. For Nietzsche, Heidegger, Foucault, and Derrida, the contested presuppositions to be set aside are as old as metaphysics itself, and are perhaps best exemplified by Plato. Postmodern philosophy has even been characterized, by Lyotard, as preceding modern philosophy, in the sense that the presuppositions of philosophical modernism emerge out of a disposition whose antecedent, unarticulated beliefs are already postmodern. Postmodern philosophy is therefore usefully regarded as a complex cluster concept that includes the following elements: an anti- or post- epistemological standpoint; anti-essentialism; anti-realism; anti-foundationalism; opposition to transcendental arguments and transcendental standpoints; rejection of the picture of knowledge as accurate representation; rejection of truth as correspondence to reality; rejection of the very idea of canonical descriptions; rejection of final vocabularies, i.e., rejection of principles, distinctions, and descriptions that are thought to be unconditionally binding for all times, persons, and places; and a suspicion of grand narratives, metanarratives of the sort perhaps best illustrated by dialectical materialism. In addition to these things postmodern philosophy is “against,” it also opposes characterizing this menu of oppositions as relativism, skepticism, or nihilism, and it rejects as “the metaphysics of presence” the traditional, putatively impossible dream of a complete, unique, and closed explanatory system, an explanatory system typically fueled by binary oppositions. On the positive side, one often finds the following themes: its critique of the notion of the neutrality and sovereignty of reason  including insistence on its pervasively gendered, historical, and ethnocentric character; its conception of the social construction of wordworld mappings; its tendency to embrace historicism; its critique of the ultimate status of a contrast between epistemology, on the one hand, and the sociology of knowledge, on the other hand; its dissolution of the notion of the autonomous, rational subject; its insistence on the artifactual status of divisions of labor in knowledge acquisition and production; and its ambivalence about the Enlightenment and its ideology. Many of these elements or elective affinities were already surfacing in the growing opposition to the spectator theory of knowledge, in Europe and in the English-speaking world, long before the term ‘postmodern’ became a commonplace. In Anglophone philosophy this took the early form of Dewey’s and pragmatism’s opposition to positivism, early Kuhn’s redescription of scientific practice, and Vitters’s insistence on the language-game character of representation; critiques of “the myth of the given” from Sellars to Davidson and Quine; the emergence of epistemology naturalized; and the putative description-dependent character of data, tethered to the theory dependence of descriptions in Kuhn, Sellars, Quine, and Arthur Fine  perhaps in all constructivists in the philosophy of science. In Europe, many of these elective affinities surfaced explicitly in and were identified with poststructuralism, although traces are clearly evident in Heidegger’s and later in Derrida’s attacks on Husserl’s residual Cartesianism; the rejection of essential descriptions Wesensanschauungen in Husserl’s sense; Saussure’s and structuralism’s attack on the autonomy and coherence of a transcendental signified standing over against a selftransparent subject; Derrida’s deconstructing the metaphysics of presence; Foucault’s redescriptions of epistemes; the convergence between - and English-speaking social constructivists; attacks on the language of enabling conditions as reflected in worries about the purchase of necessary and sufficient conditions talk on both sides of the Atlantic; and Lyotard’s many interventions, particularly those against grand narratives. Many of these elective affinities that characterize postmodern philosophy can also be seen in the virtually universal challenges to moral philosophy as it has been understood traditionally in the West, not only in G. and  philosophy, but in the reevaluation of “the morality of principles” in the work of MacIntyre, Williams, Nussbaum, John McDowell, and others. The force of postmodern critiques can perhaps best be seen in some of the challenges of feminist theory, as in the work of Judith Butler and Hélène Cixous, and gender theory generally. For it is in gender theory that the conception of “reason” itself as it has functioned in the shared philosophical tradition is redescribed as a conception that, it is often argued, is engendered, patriarchal, homophobic, and deeply optional. The term ‘postmodern’ is less clear in philosophy, its application more uncertain and divided than in some other fields, e.g., postmodern architecture. In architecture the concept is relatively clear. It displaces modernism in assignable ways, emerges as an oppositional force against architectural modernism, a rejection of the work and tradition inaugurated by Walter Gropius, Henri Le Corbusier, and Mies van der Rohe, especially the International Style. In postmodern architecture, the modernist principle of abstraction, of geometric purity and simplicity, is displaced by multivocity and pluralism, by renewed interest in buildings as signs and signifiers, interest in their referential potential and resources. The modernist’s aspiration to buildings that are timeless in an important sense is itself read by postmodernists as an iconography that privileges the brave new world of science and technology, an aspiration that glorifies uncritically the industrial revolution of which it is itself a quintessential expression. This aspiration to timelessness is displaced in postmodern architecture by a direct and self-conscious openness to and engagement with history. It is this relative specificity of the concept postmodern architecture that enabled Charles Jencks to write that “Modern Architecture died in St. Louis Missouri on July 15, 2 at 3:32 P.M.” Unfortunately, no remotely similar sentence can be written about postmodern philosophy. 

potching and cotching: Grice coined ‘cotching’ because he was irritated to hear that Chomsky couldn’t stand ‘know’ and how to coin ‘cognise’ to do duty for it! cognition -- cognitive dissonance, mental discomfort arising from conflicting beliefs or attitudes held simultaneously. Leon Festinger, who originated the theory of cognitive dissonance in a book of that title 7, suggested that cognitive dissonance has motivational characteristics. Suppose a person is contemplating moving to a new city. She is considering both Birmingham and Boston. She cannot move to both, so she must choose. Dissonance is experienced by the person if in choosing, say, Birmingham, she acquires knowledge of bad or unwelcome features of Birmingham and of good or welcome aspects of Boston. The amount of dissonance depends on the relative intensities of dissonant elements. Hence, if the only dissonant factor is her learning that Boston is cooler than Birmingham, and she does not regard climate as important, she will experience little dissonance. Dissonance may occur in several sorts of psychological states or processes, although the bulk of research in cognitive dissonance theory has been on dissonance in choice and on the justification and psychological aftereffects of choice. Cognitive dissonance may be involved in two phenomena of interest to philosophers, namely, self-deception and weakness of will. Why do self-deceivers try to get themselves to believe something that, in some sense, they know to be false? One may resort to self-deception when knowledge causes dissonance. Why do the weak-willed perform actions they know to be wrong? One may become weak-willed when dissonance arises from the expected consequences of doing the right thing. -- cognitive psychotherapy, an expression introduced by Brandt in A Theory of the Good and the Right to refer to a process of assessing and adjusting one’s desires, aversions, or pleasures henceforth, “attitudes”. This process is central to Brandt’s analysis of rationality, and ultimately, to his view on the justification of morality. Cognitive psychotherapy consists of the agent’s criticizing his attitudes by repeatedly representing to himself, in an ideally vivid way and at appropriate times, all relevant available information. Brandt characterizes the key definiens as follows: 1 available information is “propositions accepted by the science of the agent’s day, plus factual propositions justified by publicly accessible evidence including testimony of others about themselves and the principles of logic”; 2 information is relevant provided, if the agent were to reflect repeatedly on it, “it would make a difference,” i.e., would affect the attitude in question, and the effect would be a function of its content, not an accidental byproduct; 3 relevant information is represented in an ideally vivid way when the agent focuses on it with maximal clarity and detail and with no hesitation or doubt about its truth; and 4 repeatedly and at appropriate times refer, respectively, to the frequency and occasions that would result in the information’s having the maximal attitudinal impact. Suppose Mary’s desire to smoke were extinguished by her bringing to the focus of her attention, whenever she was about to inhale smoke, some justified beliefs, say that smoking is hazardous to one’s health and may cause lung cancer; Mary’s desire would have been removed by cognitive psychotherapy. According to Brandt, an attitude is rational for a person provided it is one that would survive, or be produced by, cognitive psychotherapy; otherwise it is irrational. Rational attitudes, in this sense, provide a basis for moral norms. Roughly, the correct moral norms are those of a moral code that persons would opt for if i they were motivated by attitudes that survive the process of cognitive psychotherapy; and ii at the time of opting for a moral code, they were fully aware of, and vividly attentive to, all available information relevant to choosing a moral code for a society in which they are to live for the rest of their lives. In this way, Brandt seeks a value-free justification for moral norms  one that avoids the problems of other theories such as those that make an appeal to intuitions.  -- cognitive science, an interdisciplinary research cluster that seeks to account for intelligent activity, whether exhibited by living organisms especially adult humans or machines. Hence, cognitive psychology and artificial intelligence constitute its core. A number of other disciplines, including neuroscience, linguistics, anthropology, and philosophy, as well as other fields of psychology e.g., developmental psychology, are more peripheral contributors. The quintessential cognitive scientist is someone who employs computer modeling techniques developing computer programs for the purpose of simulating particular human cognitive activities, but the broad range of disciplines that are at least peripherally constitutive of cognitive science have lent a variety of research strategies to the enterprise. While there are a few common institutions that seek to unify cognitive science e.g., departments, journals, and societies, the problems investigated and the methods of investigation often are limited to a single contributing discipline. Thus, it is more appropriate to view cognitive science as a cross-disciplinary enterprise than as itself a new discipline. While interest in cognitive phenomena has historically played a central role in the various disciplines contributing to cognitive science, the term properly applies to cross-disciplinary activities that emerged in the 0s. During the preceding two decades each of the disciplines that became part of cogntive science gradually broke free of positivistic and behavioristic proscriptions that barred systematic inquiry into the operation of the mind. One of the primary factors that catalyzed new investigations of cognitive activities was Chomsky’s generative grammar, which he advanced not only as an abstract theory of the structure of language, but also as an account of language users’ mental knowledge of language their linguistic competence. A more fundamental factor was the development of approaches for theorizing about information in an abstract manner, and the introduction of machines computers that could manipulate information. This gave rise to the idea that one might program a computer to process information so as to exhibit behavior that would, if performed by a human, require intelligence. If one tried to formulate a unifying question guiding cognitive science research, it would probably be: How does the cognitive system work? But even this common question is interpreted quite differently in different disciplines. We can appreciate these differences by looking just at language. While psycholinguists generally psychologists seek to identify the processing activities in the mind that underlie language use, most linguists focus on the products of this internal processing, seeking to articulate the abstract structure of language. A frequent goal of computer scientists, in contrast, has been to develop computer programs to parse natural language input and produce appropriate syntactic and semantic representations. These differences in objectives among the cognitive science disciplines correlate with different methodologies. The following represent some of the major methodological approaches of the contributing disciplines and some of the problems each encounters. Artificial intelligence. If the human cognition system is viewed as computational, a natural goal is to simulate its performance. This typically requires formats for representing information as well as procedures for searching and manipulating it. Some of the earliest AIprograms drew heavily on the resources of first-order predicate calculus, representing information in propositional formats and manipulating it according to logical principles. For many modeling endeavors, however, it proved important to represent information in larger-scale structures, such as frames Marvin Minsky, schemata David Rumelhart, or scripts Roger Schank, in which different pieces of information associated with an object or activity would be stored together. Such structures generally employed default values for specific slots specifying, e.g., that deer live in forests that would be part of the representation unless overridden by new information e.g., that a particular deer lives in the San Diego Zoo. A very influential alternative approach, developed by Allen Newell, replaces declarative representations of information with procedural representations, known as productions. These productions take the form of conditionals that specify actions to be performed e.g., copying an expression into working memory if certain conditions are satisfied e.g., the expression matches another expression. Psychology. While some psychologists develop computer simulations, a more characteristic activity is to acquire detailed data from human subjects that can reveal the cognitive system’s actual operation. This is a challenging endeavor. While cognitive activities transpire within us, they frequently do so in such a smooth and rapid fashion that we are unaware of them. For example, we have little awareness of what occurs when we recognize an object as a chair or remember the name of a client. Some cognitive functions, though, seem to be transparent to consciousness. For example, we might approach a logic problem systematically, enumerating possible solutions and evaluating them serially. Allen Newell and Herbert Simon have refined methods for exploiting verbal protocols obtained from subjects as they solve such problems. These methods have been quite fruitful, but their limitations must be respected. In many cases in which we think we know how we performed a cognitive task, Richard Nisbett and Timothy Wilson have argued that we are misled, relying on folk theories to describe how our minds work rather than reporting directly on their operation. In most cases cognitive psychologists cannot rely on conscious awareness of cognitive processes, but must proceed as do physiologists trying to understand metabolism: they must devise experiments that reveal the underlying processes operative in cognition. One approach is to seek clues in the errors to which the cognitive system cognitive science cognitive science is prone. Such errors might be more easily accounted for by one kind of underlying process than by another. Speech errors, such as substituting ‘bat cad’ for ‘bad cat’, may be diagnostic of the mechanisms used to construct speech. This approach is often combined with strategies that seek to overload or disrupt the system’s normal operation. A common technique is to have a subject perform two tasks at once  e.g., read a passage while watching for a colored spot. Cognitive psychologists may also rely on the ability to dissociate two phenomena e.g., obliterate one while maintaining the other to establish their independence. Other types of data widely used to make inferences about the cognitive system include patterns of reaction times, error rates, and priming effects in which activation of one item facilitates access to related items. Finally, developmental psychologists have brought a variety of kinds of data to bear on cognitive science issues. For example, patterns of acquisition times have been used in a manner similar to reaction time patterns, and accounts of the origin and development of systems constrain and elucidate mature systems. Linguistics. Since linguists focus on a product of cognition rather than the processes that produce the product, they tend to test their analyses directly against our shared knowledge of that product. Generative linguists in the tradition of Chomsky, for instance, develop grammars that they test by probing whether they generate the sentences of the language and no others. While grammars are certainly G.e to developing processing models, they do not directly determine the structure of processing models. Hence, the central task of linguistics is not central to cognitive science. However, Chomsky has augmented his work on grammatical description with a number of controversial claims that are psycholinguistic in nature e.g., his nativism and his notion of linguistic competence. Further, an alternative approach to incorporating psycholinguistic concerns, the cognitive linguistics of Lakoff and Langacker, has achieved prominence as a contributor to cognitive science. Neuroscience. Cognitive scientists have generally assumed that the processes they study are carried out, in humans, by the brain. Until recently, however, neuroscience has been relatively peripheral to cognitive science. In part this is because neuroscientists have been chiefly concerned with the implementation of processes, rather than the processes themselves, and in part because the techniques available to neuroscientists such as single-cell recording have been most suitable for studying the neural implementation of lower-order processes such as sensation. A prominent exception was the classical studies of brain lesions initiated by Broca and Wernicke, which seemed to show that the location of lesions correlated with deficits in production versus comprehension of speech. More recent data suggest that lesions in Broca’s area impair certain kinds of syntactic processing. However, other developments in neuroscience promise to make its data more relevant to cognitive modeling in the future. These include studies of simple nervous systems, such as that of the aplysia a genus of marine mollusk by Eric Kandel, and the development of a variety of techniques for determining the brain activities involved in the performance of cognitive tasks e.g., recording of evoked response potentials over larger brain structures, and imaging techniques such as positron emission tomography. While in the future neuroscience is likely to offer much richer information that will guide the development and constrain the character of cognitive models, neuroscience will probably not become central to cognitive science. It is itself a rich, multidisciplinary research cluster whose contributing disciplines employ a host of complicated research tools. Moreover, the focus of cognitive science can be expected to remain on cognition, not on its implementation. So far cognitive science has been characterized in terms of its modes of inquiry. One can also focus on the domains of cognitive phenomena that have been explored. Language represents one such domain. Syntax was one of the first domains to attract wide attention in cognitive science. For example, shortly after Chomsky introduced his transformational grammar, psychologists such as George Miller sought evidence that transformations figured directly in human language processing. From this beginning, a more complex but enduring relationship among linguists, psychologists, and computer scientists has formed a leading edge for much cognitive science research. Psycholinguistics has matured; sophisticated computer models of natural language processing have been developed; and cognitive linguists have offered a particular synthesis that emphasizes semantics, pragmatics, and cognitive foundations of language. Thinking and reasoning. These constitute an important domain of cognitive science that is closely linked to philosophical interests. Problem cognitive science cognitive science solving, such as that which figures in solving puzzles, playing games, or serving as an expert in a domain, has provided a prototype for thinking. Newell and Simon’s influential work construed problem solving as a search through a problem space and introduced the idea of heuristics  generally reliable but fallible simplifying devices to facilitate the search. One arena for problem solving, scientific reasoning and discovery, has particularly interested philosophers. Artificial intelligence researchers such as Simon and Patrick Langley, as well as philosophers such as Paul Thagard and Lindley Darden, have developed computer programs that can utilize the same data as that available to historical scientists to develop and evaluate theories and plan future experiments. Cognitive scientists have also sought to study the cognitive processes underlying the sorts of logical reasoning both deductive and inductive whose normative dimensions have been a concern of philosophers. Philip JohnsonLaird, for example, has sought to account for human performance in dealing with syllogistic reasoning by describing a processing of constructing and manipulating mental models. Finally, the process of constructing and using analogies is another aspect of reasoning that has been extensively studied by traditional philosophers as well as cognitive scientists. Memory, attention, and learning. Cognitive scientists have differentiated a variety of types of memory. The distinction between long- and short-term memory was very influential in the information-processing models of the 0s. Short-term memory was characterized by limited capacity, such as that exhibited by the ability to retain a seven-digit telephone number for a short period. In much cognitive science work, the notion of working memory has superseded short-term memory, but many theorists are reluctant to construe this as a separate memory system as opposed to a part of long-term memory that is activated at a given time. Endel Tulving introduced a distinction between semantic memory general knowledge that is not specific to a time or place and episodic memory memory for particular episodes or occurrences. More recently, Daniel Schacter proposed a related distinction that emphasizes consciousness: implicit memory access without awareness versus explicit memory which does involve awareness and is similar to episodic memory. One of the interesting results of cognitive research is the dissociation between different kinds of memory: a person might have severely impaired memory of recent events while having largely unimpaired implicit memory. More generally, memory research has shown that human memory does not simply store away information as in a file cabinet. Rather, information is organized according to preexisting structures such as scripts, and can be influenced by events subsequent to the initial storage. Exactly what gets stored and retrieved is partly determined by attention, and psychologists in the information-processing tradition have sought to construct general cognitive models that emphasize memory and attention. Finally, the topic of learning has once again become prominent. Extensively studied by the behaviorists of the precognitive era, learning was superseded by memory and attention as a research focus in the 0s. In the 0s, artificial intelligence researchers developed a growing interest in designing systems that can learn; machine learning is now a major problem area in AI. During the same period, connectionism arose to offer an alternative kind of learning model. Perception and motor control. Perceptual and motor systems provide the inputs and outputs to cognitive systems. An important aspect of perception is the recognition of something as a particular kind of object or event; this requires accessing knowledge of objects and events. One of the central issues concerning perception questions the extent to which perceptual processes are influenced by higher-level cognitive information top-down processing versus how much they are driven purely by incoming sensory information bottom-up processing. A related issue concerns the claim that visual imagery is a distinct cognitive process and is closely related to visual perception, perhaps relying on the same brain processes. A number of cognitive science inquiries e.g., by Roger Shepard and Stephen Kosslyn have focused on how people use images in problem solving and have sought evidence that people solve problems by rotating images or scanning them. This research has been extremely controversial, as other investigators have argued against the use of images and have tried to account for the performance data that have been generated in terms of the use of propositionally represented information. Finally, a distinction recently has been proposed between the What and Where systems. All of the foregoing issues concern the What system which recognizes and represents objects as exemplars of categories. The Where system, in contrast, concerns objects in their environment, and is particularly adapted to the dynamics of movement. Gibson’s ecological psychology is a long-standing inquiry into this aspect of perception, and work on the neural substrates is now attracting the interest of cognitive scientists as well. Recent developments. The breadth of cognitive science has been expanding in recent years. In the 0s, cognitive science inquiries tended to focus on processing activities of adult humans or on computer models of intelligent performance; the best work often combined these approaches. Subsequently, investigators examined in much greater detail how cognitive systems develop, and developmental psychologists have increasingly contributed to cognitive science. One of the surprising findings has been that, contrary to the claims of William James, infants do not seem to confront the world as a “blooming, buzzing confusion,” but rather recognize objects and events quite early in life. Cognitive science has also expanded along a different dimension. Until recently many cognitive studies focused on what humans could accomplish in laboratory settings in which they performed tasks isolated from reallife contexts. The motivation for this was the assumption that cognitive processes were generic and not limited to specific contexts. However, a variety of influences, including Gibsonian ecological psychology especially as interpreted and developed by Ulric Neisser and Soviet activity theory, have advanced the view that cognition is much more dynamic and situated in real-world tasks and environmental contexts; hence, it is necessary to study cognitive activities in an ecologically valid manner. Another form of expansion has resulted from a challenge to what has been the dominant architecture for modeling cognition. An architecture defines the basic processing capacities of the cognitive system. The dominant cognitive architecture has assumed that the mind possesses a capacity for storing and manipulating symbols. These symbols can be composed into larger structures according to syntactic rules that can then be operated upon by formal rules that recognize that structure. Jerry Fodor has referred to this view of the cognitive system as the “language of thought hypothesis” and clearly construes it as a modern heir of rationalism. One of the basic arguments for it, due to Fodor and Zenon Pylyshyn, is that thoughts, like language, exhibit productivity the unlimited capacity to generate new thoughts and systematicity exhibited by the inherent relation between thoughts such as ‘Joan loves the florist’ and ‘The florist loves Joan’. They argue that only if the architecture of cognition has languagelike compositional structure would productivity and systematicity be generic properties and hence not require special case-by-case accounts. The challenge to this architecture has arisen with the development of an alternative architecture, known as connectionism, parallel distributed processing, or neural network modeling, which proposes that the cognitive system consists of vast numbers of neuronlike units that excite or inhibit each other. Knowledge is stored in these systems by the adjustment of connection strengths between processing units; consequently, connectionism is a modern descendant of associationism. Connectionist networks provide a natural account of certain cognitive phenomena that have proven challenging for the symbolic architecture, including pattern recognition, reasoning with soft constraints, and learning. Whether they also can account for productivity and systematicity has been the subject of debate. Philosophical theorizing about the mind has often provided a starting point for the modeling and empirical investigations of modern cognitive science. The ascent of cognitive science has not meant that philosophers have ceased to play a role in examining cognition. Indeed, a number of philosophers have pursued their inquiries as contributors to cognitive science, focusing on such issues as the possible reduction of cognitive theories to those of neuroscience, the status of folk psychology relative to emerging scientific theories of mind, the merits of rationalism versus empiricism, and strategies for accounting for the intentionality of mental states. The interaction between philosophers and other cognitive scientists, however, is bidirectional, and a number of developments in cognitive science promise to challenge or modify traditional philosophical views of cognition. For example, studies by cognitive and social psychologists have challenged the assumption that human thinking tends to accord with the norms of logic and decision theory. On a variety of tasks humans seem to follow procedures heuristics that violate normative canons, raising questions about how philosophers should characterize rationality. Another area of empirical study that has challenged philosophical assumptions has been the study of concepts and categorization. Philosophers since Plato have widely assumed that concepts of ordinary language, such as red, bird, and justice, should be definable by necessary and sufficient conditions. But celebrated studies by Eleanor Rosch and her colleagues indicated that many ordinary-language concepts had a prototype structure instead. On this view, the categories employed in human thinking are characterized by prototypes the clearest exemplars and a metric that grades exemplars according to their degree of typicality. Recent investigations have also pointed to significant instability in conceptual structure and to the role of theoretical beliefs in organizing categories. This alternative conception of concepts has profound implications for philosophical methodologies that portray philosophy’s task to be the analysis of concepts. 

Potentia -- dunamis, also dynamis Grecian, ‘power’, ‘capacity’, as used by pre-Socratics such as Anaximander and Anaxagoras, one of the elementary character-powers, such as the hot or the cold, from which they believed the world was constructed. Plato’s early theory of Forms borrowed from the concept of character-powers as causes present in things; courage, e.g., is treated in the Laches as a power in the soul. Aristotle also used the word in this sense to explain the origins of the elements. In the Metaphysics especially Book IX, Aristotle used dunamis in a different sense to mean ‘potentiality’ in contrast to ‘actuality’ energeia or entelecheia. In the earlier sense of dunamis, matter is treated as potentiality, in that it has the potential to receive form and so be actualized as a concrete substance. In the later Aristotelian sense of dunamis, dormant abilities are treated as potentialities, and dunamis is to energeia as sleeping is to waking, or having sight to seeing.  Potentia -- dynamic logic, a branch of logic in which, in addition to the usual category of formulas interpretable as propositions, there is a category of expressions interpretable as actions. Dynamic logic originally called the modal logic of programs emerged in the late 0s as one step in a long tradition within theoretical computer science aimed at providing a way to formalize the analysis of programs and their action. A particular concern here was program verification: what can be said of the effect of a program if started at a certain point? To this end operators [a] and ‹a were introduced with the following intuitive readings: [a]A to mean ‘after every terminating computation according to a it is the case that A’ and ‹aA to mean ‘after some terminating computation according to a it is the case that A’. The logic of these operators may be seen as a generalization of ordinary modal logic: where modal logic has one box operator A and one diamond operator B, dynamic logic has one box operator [a] and one diamond operator ‹a for every program expression a in the language. In possible worlds semantics for modal logic a model is a triple U, R, V where U is a universe of points, R a binary relation, and V a valuation assigning to each atomic formula a subset of U. In dynamic logic, a model is a triple U, R, V where U and V are as before but R is a family of binary relations Ra, one for every program expression a in the language. Writing ‘Xx A’, where x is a point in U, for ‘A is true at x’ in the model in question, we have the following characteristic truth conditions truth-functional compounds are evaluated by truth tables, as in modal logic: Xx P if and only if x is a point in VP, where P is an atomic formula, Xx[a]A if and only if, for all y, if x is Ra- related to y then Xy A, Xx ‹a if and only if, for some y, x is Ra-related to y and Xy A. Traditionally, dynamic logic will contain machinery for rendering the three regular operators on programs: ‘!’ sum, ‘;’ composition, and ‘*’ Kleene’s star operation, as well as the test operator ‘?’, which, operating on a proposition, will yield a program. The action a ! b consists in carrying out a or carrying out b; the action a;b in first carrying out a, then carrying out b; the action a* in carrying out a some finite number of times not excluding 0; the action ?A in verifying that A. Only standard models reflect these intuitions: Ra ! b % Ra 4 Rb, Ra;b % Ra _ Rb, Ra* % Ra*, R?A % {x,x : Xx A} where ‘*’ is the ancestral star The smallest propositional dynamic logic PDL is the set of formulas true at every point in every standard model. Note that dynamic logic analyzes non-deterministic action  this is evident at the level of atomic programs p where Rp is a relation, not necessarily a function, and also in the definitions of Ra + b and Ra*. Dynamic logic has been extended in various ways, e.g., to first- and second-order predicate logic. Furthermore, just as deontic logic, tense logic, etc., are referred to as modal logic in the wide sense, so extensions of dynamic logic in the narrow sense such as process logic are often loosely referred to as dynamic logic in the wide sense. Dyad dynamic logic 250   250 The philosophical interest in dynamic logic rests with the expectation that it will prove a fruitful instrument for analyzing the concept of action in general: a successful analysis would be valuable in itself and would also be relevant to other disciplines such as deontic logic and the logic of imperatives.  potency, for Aristotle, a kind of capacity that is a correlative of action. We require no instruction to grasp the difference between ‘X can do Y’ and ‘X is doing Y’, the latter meaning that the deed is actually being done. That an agent has a potency to do something is not a pure prediction so much as a generalization from past performance of individual or kind. Aristotle uses the example of a builder, meaning someone able to build, and then confronts the Megaric objection that the builder can be called a builder only when he actually builds. Clearly one who is doing something can do it, but Aristotle insists that the napping carpenter has the potency to hammer and saw. A potency based on an acquired skill like carpentry derives from the potency shared by those who acquire and those who do not acquire the skill. An unskilled worker can be said to be a builder “in potency,” not in the sense that he has the skill and can employ it, but in the sense that he can acquire the skill. In both acquisition and employment, ‘potency’ refers to the actual  either the actual acquisition of the skill or its actual use. These post-structuralism potency 726    726 potentiality, first practical attitude 727 correlatives emerged from Aristotle’s analysis of change and becoming. That which, from not having the skill, comes to have it is said to be “in potency” to that skill. From not having a certain shape, wood comes to have a certain shape. In the shaped wood, a potency is actualized. Potency must not be identified with the unshaped, with what Aristotle calls privation. Privation is the negation of P in a subject capable of P. Parmenides’ identification of privation and potency, according to Aristotle, led him to deny change. How can not-P become P? It is the subject of not-P to which the change is attributed and which survives the change that is in potency to X.  Potestas – Energeia – actus – entelechia -- power, a disposition; an ability or capacity to yield some outcome. One tradition which includes Locke distinguishes active and passive powers. A knife has the active power to slice an apple, which has the passive power to be sliced by the knife. The distinction seems largely grammatical, however. Powers act in concert: the power of a grain of salt to dissolve in water and the water’s power to dissolve the salt are reciprocal and their manifestations mutual. Powers or dispositions are sometimes thought to be relational properties of objects, properties possessed only in virtue of objects standing in appropriate relations to other objects. However, if we distinguish, as we must, between a power and its manifestation, and if we allow that an object could possess a power that it never manifested a grain of salt remains soluble even if it never dissolves, it would seem that an object could possess a power even if appropriate reciprocal partners for its manifestation were altogether non-existent. This appears to have been Locke’s view An Essay concerning Human Understanding, 1690 of “secondary qualities” colors, sounds, and the like, which he regarded as powers of objects to produce certain sorts of sensory experience in observers. Philosophers who take powers seriously disagree over whether powers are intrinsic, “built into” properties this view, defended by C. B. Martin, seems to have been Locke’s, or whether the connection between properties and the powers they bestow is contingent, dependent perhaps upon contingent laws of nature a position endorsed by Armstrong. Is the solubility of salt a characteristic built into the salt, or is it a “second-order” property possessed by the salt in virtue of i the salt’s possession of some “firstorder” property and ii the laws of nature? Reductive analyses of powers, though influential, have not fared well. Suppose a grain of salt is soluble in water. Does this mean that if the salt were placed in water, it would dissolve? No. Imagine that were the salt placed in water, a technician would intervene, imposing an electromagnetic field, thereby preventing the salt from dissolving. Attempts to exclude “blocking” conditions  by appending “other things equal” clauses perhaps  face charges of circularity: in nailing down what other things must be equal we find ourselves appealing to powers. Powers evidently are fundamental features of our world. In the romance languages, “it may run” means “It has power to rain.” “Il peut …”  This has a cognate in the Germanic languages, “it might rain.” “Might is right.”

Potts: “One of the few non-Oxonian English philosohpers I can stand, but then he was my genial tutee!, so he IS Oxford. Oxford made me and him!” --. English philosopher, tutee of H. P. Grice. Semanticist of the best order! Structures and Categories for the Representation of Meaning T.C. Potts. Potts, alla Grice, addresses the representation problem ... how best to represent the meanings of linguistic expressions... One might call this the 'semantic form' of expressions (p. xi, italics in the original). The book begins with "three chapters in which I survey the contributions made by linguistics, logic and computer science respectively to the representation of meaning" (p. xii). These three chapters are not easy to understand, principally because of Potts's obtuse style, an example of which is that instead of saying "'either P or Q' is false if 'P' and 'Q' are both false; otherwise, it is true," he says, "we lay down that a proposition having the structure represented by 'either P or Q' is to be accounted false if a false proposition is substituted for 'P' and a false proposition for 'Q', but is otherwise to be accounted true" (p. 53). These chapters are also outdated. In particular, the chapter on computer science, discussing the work of researchers whose goals are the closest to Potts's own stated goals, is mainly a review of work as of the seventies. There are citations to several of the papers in Findler (1979), but only three to more recent research publications: Hayes (1980), Sowa (1984), and Hobbs and Shieber (1987). Perhaps the most valuable aspect of these three chapters is Potts's criticisms of some of the work he surveys. Of course, some of the problems noted have been corrected in literature that Potts hasn't yet got around to reading. By the end of the three survey chapters, Potts has introduced two techniques that he 427  Computational Linguistics Volume 21, Number 3 then develops into his own representation-- categorial grammars and graphs as representation formalisms. He takes the categorial analysis to be the prior of the two, with his graphs, which he calls categorialgraphs, being the clearer representation of sentence meaning. Unfortunately, "formalism" and "clearer" must be taken with a grain of salt. Potts never formally defines his categorial graphs, let alone gives a formal semantics for them. Although I have had extensive experience reading, interpreting, and devising graphical representations of meaning, I could not understand the details of Potts's graphs. But then, neither, apparently, can he: "The relationship between semantic and syntactic structures has not been spelled out, so that it is not fully determinate what our semantic representations represent at the syntactic level" (p. 168). The four substantive chapters are useful for the linguistic issues that they address, even if they are not useful for the representation scheme that they develop. These issues, which must eventually be faced by all knowledge representation formalisms that aspire to complete coverage of natural language include: quantifier scope; pronouns; relative clauses; count nouns, substance nouns, and proper names; generic propositions; deictic terms; plurals; identity; and adverbs. Appropriately, the book does not end on a note of claimed accomplishment, but on a note of work yet to do: "The purpose of a philosophical book is to stimulate thought, not to put it to rest with solutions to every problem ... It is still premature to formulate a graph grammar for semantic representation of everyday language... The representation problem is commonly not accorded the respect which it deserves" (p. 288). Many people agree, and have, accordingly, produced a vast literature that Potts is apparently not familiar with. (Some relevant collections are Cercone and McCalla 1987, Sowa 1991, and Lehmann 1992.) Nevertheless, Potts is still correct when he suggests that there is much work left to do.--Stuart C.

Stimulus-response -- poverty of the stimulus, a psychological phenomenon exhibited when behavior is stimulusunbound, and hence the immediate stimulus characterized in straightforward physical terms does not completely control behavior. Human beings sort stimuli in various ways and hosts of influences seem to affect when, why, and how we respond  our background beliefs, facility with language, hypotheses about stimuli, etc. Suppose a person visiting a museum notices a painting she has never before seen. Pondering the unfamiliar painting, she says, “an ambitious visual synthesis of the music of Mahler and the poetry of Keats.” If stimulus painting controls response, then her utterance is a product of earlier responses to similar stimuli. Given poverty of the stimulus, no such control is exerted by the stimulus the painting. Of course, some influence of response must be conceded to the painting, for without it there would be no utterance. However, the utterance may well outstrip the visitor’s conditioning and learning history. Perhaps she had never before talked of painting in terms of music and poetry. The linguist Noam Chomsky made poverty of the stimulus central to his criticism of B. F. Skinner’s Verbal Behavior 7. Chomsky argued that there is no predicting, and certainly no critical stimulus control of, much human behavior.


practical reason, the capacity for argument or demonstrative inference, considered in its application to the task of prescribing or selecting behavior. Some philosophical concerns in this area pertain to the actual thought processes by which plans of action are formulated and carried out in practical situations. A second major issue is what role, if any, practical reason plays in determining norms of conduct. Here there are two fundamental positions. Instrumentalism is typified by Hume’s claim that reason is, and ought only to be, the slave of the passions. According to instrumentalism, reason by itself is incapable of influencing action directly. It may do so indirectly, by disclosing facts that arouse motivational impulses. And it fulfills an indispensable function in discerning meansend relations by which our objectives may be attained. But none of those objectives is set by reason. All are set by the passions  the desiderative and aversive impulses aroused in us by what our cognitive faculties apprehend. It does not follow from this alone that ethical motivation reduces to mere desire and aversion, based on the pleasure and pain different courses of action might afford. There might yet be a specifically ethical passion, or it might be that independently based moral injunctions have in themselves a special capacity to provoke ordinary desire and aversion. Nevertheless, instrumentalism is often associated with the view that pleasure and pain, happiness and unhappiness, are the sole objects of value and disvalue, and hence the only possible motivators of conduct. Hence, it is claimed, moral injunctions must be grounded in these motives, and practical reason is of interest only as subordinated to inclination. The alternative to instrumentalism is the view championed by Kant, that practical reason is an autonomous source of normative principles, capable of motivating behavior independently of ordinary desire and aversion. On this view it is the passions that lack intrinsic moral import, and the function of practical reason is to limit their motivational role by formulating normative principles binding for all rational agents and founded in the operation of practical reason itself. Theories of this kind usually view moral principles as grounded in consistency, and an impartial respect for the autonomy of all rational agents. To be morally acceptable, principles of conduct must be universalizable, so that all rational agents could behave in the same way without their conduct either destroying itself or being inconsistently motivated. There are advantages and disadvantages to each of these views. Instrumentalism offers a simpler account of both the function of practical reason and the sources of human motivation. But it introduces a strong subjective element by giving primacy to desire, thereby posing a problem of how moral principles can be universally binding. The Kantian approach offers more promise here, since it makes universalizability essential to any type of behavior being moral. But it is more complex, and the claim that the deliverances of practical reason carry intrinsic motivational force is open to challenge.   practical reasoning, the inferential process by which considerations for or against envisioned courses of action are brought to bear on the formation and execution of intention. The content of a piece of practical reasoning is a practical argument. Practical arguments can be complex, but they are often summarized in syllogistic form. Important issues concerning practical reasoning include how it relates to theoretical reasoning, whether it is a causal process, and how it can be evaluated. Theories of practical reasoning tend to divide into two basic categories. On one sort of view, the intrinsic features of practical reasoning exhibit little or no difference from those of theoretical reasoning. What makes practical reasoning practical is its subject matter and motivation. Hence the following could be a bona fide practical syllogism: Exercise would be good for me. Jogging is exercise. Therefore, jogging would be good for me. This argument has practical subject matter, and if made with a view toward intention formation it would be practical in motivation also. But it consists entirely of propositions, which are appropriate contents for belief-states. In principle, therefore, an agent could accept its conclusion without intending or even desiring to jog. Intention formation requires a further step. But if the content of an intention cannot be a proposition, that step could not count in itself as practical reasoning unless such reasoning can employ the contents of strictly practical mental states. Hence many philosophers call for practical syllogisms such as: Would that I exercise. Jogging is exercise. Therefore, I shall go jogging. Here the first premise is optative and understood to represent the content of a desire, and the conclusion is the content of a decision or act of intention formation. These contents are not true or false, and so are not propositions. Theories that restrict the contents of practical reasoning to propositions have the advantage that they allow such reasoning to be evaluated in terms of familiar logical principles. Those that permit the inclusion of optative content entail a need for more complex modes of evaluation. However, they bring more of the process of intention formation under the aegis of reason; also, they can be extended to cover the execution of intentions, in terms of syllogisms that terminate in volition. Both accounts must deal with cases of self-deception, in which the considerations an agent cites to justify a decision are not those from which it sprang, and cases of akrasia, where the agent views one course of action as superior, yet carries out another. Because mental content is always abstract, it cannot in itself be a nomic cause of behavior. But the states and events to which it belongs  desires, beliefs, etc.  can count as causes, and are so treated in deterministic explanations of action. Opponents of determinism reject this step, and seek to explain action solely through the teleological or justifying force carried by mental content. Practical syllogisms often summarize very complex thought processes, in which multiple options are considered, each with its own positive and negative aspects. Some philosophers hold that when successfully concluded, this process issues in a judgment of what action would be best all things considered  i.e., in light of all relevant considerations. Practical reasoning can be evaluated in numerous ways. Some concern the reasoning process itself: whether it is timely and duly considers the relevant alternatives, as well as whether it is well structured logically. Other concerns have to do with the products of practical reasoning. Decisions may be deemed irrational if they result in incompatible intentions, or conflict with the agent’s beliefs regarding what is possible. They may also be criticized if they conflict with the agent’s best interests. Finally, an agent’s intentions can fail to accord with standards of morality. The relationship among these ways of evaluating intentions is important to the foundations of ethics. 

practition, Castaneda’s term for the characteristic content of practical thinking. Each practition represents an action as something to be done, say, as intended, commanded, recommended, etc., and not as an accomplishment or prediction. Thus, unlike propositions, practitions are not truth-valued, but they can be components of valid arguments and so possess values akin to truth; e.g., the command ‘James, extinguish your cigar!’ seems legitimate given that James is smoking a cigar in a crowded bus. Acknowledging practitions is directly relevant to many other fields. 

praedicamenta singular: praedicamentum, in medieval philosophy, the ten Aristotelian categories: substance, quantity, quality, relation, where, when, position i.e., orientation  e.g., “upright”, having, action, and passivity. These were the ten most general of all genera. All of them except substance were regarded as accidental. It was disputed whether this tenfold classification was intended as a linguistic division among categorematic terms or as an ontological division among extralinguistic realities. Some authors held that the division was primarily linguistic, and that extralinguistic realities were divided according to some but not all the praedicamenta. Most authors held that everything in any way real belonged to one praedicamentum or another, although some made an exception for God. But authors who believed in complexe significabile usually regarded them as not belonging to any praedicamentum. 

pragmatic contradiction, a contradiction that is generated by pragmatic rather than logical implication. A logically implies B if it is impossible for B to be false if A is true, whereas A pragmatically implies B if in most but not necessarily all contexts, saying ‘A’ can reasonably be taken as indicating that B is true. Thus, if I say, “It’s raining,” what I say does not logically imply that I believe that it is raining, since it is possible for it to be raining without my believing it is. Nor does my saying that it is raining logically imply that I believe that it is, since it is possible for me to say this without believing it. But my saying this does pragmatically imply that I believe that it is raining, since normally my saying this can reasonably be taken to indicate that I believe it. Accordingly, if I were to say, “It’s raining but I don’t believe that it’s raining,” the result would be a pragmatic contradiction. The first part “It’s raining” does not logically imply the negation of the second part “I don’t believe that it’s raining” but my saying the first part does pragmatically imply the negation of the second part. 

Old-World pragmatism: a philosophy that stresses the relation of theory to praxis and takes the continuity of experience and nature as revealed through the outcome of directed action as the starting point for reflection. Experience is the ongoing transaction of organism and environment, i.e., both subject and object are constituted in the process. When intelligently ordered, initial conditions are deliberately transformed according to ends-inview, i.e., intentionally, into a subsequent state of affairs thought to be more desirable. Knowledge is therefore guided by interests or values. Since the reality of objects cannot be known prior to experience, truth claims can be justified only as the fulfillment of conditions that are experimentally determined, i.e., the outcome of inquiry. As a philosophic movement, pragmatism was first formulated by Peirce in the early 1870s in the Metaphysical Club in Cambridge, Massachusetts; it was announced as a distinctive position in James’s 8 address to the Philosophical Union at the  of California at Berkeley, and further elaborated according to the Chicago School, especially by Dewey, Mead, and Jane Addams 18605. Emphasis on the reciprocity of theory and praxis, knowledge and action, facts and values, follows from its postDarwinian understanding of human experience, including cognition, as a developmental, historically contingent, process. C. I. Lewis’s pragmatic a priori and Quine’s rejection of the analytic synthetic distinction develop these insights further. Knowledge is instrumental  a tool for organizing experience satisfactorily. Concepts are habits of belief or rules of action. Truth cannot be determined solely by epistemological criteria because the adequacy of these criteria cannot be determined apart from the goals sought and values instantiated. Values, which arise in historically specific cultural situations, are intelligently appropriated only to the extent that they satisfactorily resolve problems and are judged worth retaining. According to pragmatic theories of truth, truths are beliefs that are confirmed in the course of experience and are therefore fallible, subject to further revision. True beliefs for Peirce represent real objects as successively confirmed until they converge on a final determination; for James, leadings that are worthwhile; and according to Dewey’s theory of inquiry, the transformation of an indeterminate situation into a determinate one that leads to warranted assertions. Pragmatic ethics is naturalistic, pluralistic, developmental, and experimental. It reflects on the motivations influencing ethical systems, examines the individual developmental process wherein an individual’s values are gradually distinguished from those of society, situates moral judgments within problematic situations irreducibly individual and social, and proposes as ultimate criteria for decision making the value for life as growth, determined by all those affected by the actual or projected outcomes. The original interdisciplinary development of pragmatism continues in its influence on the humanities. Oliver Wendell Holmes, Jr., member of the Metaphysical Club, later justice of the U.S. Supreme Court, developed a pragmatic theory of law. Peirce’s Principle of Pragmatism, by which meaning resides in conceivable practical effects, and his triadic theory of signs developed into the field of semiotics. James’s Principles of Psychology 0 not only established experimental psychology in North America, but shifted philosophical attention away from abstract analyses of rationality to the continuity of the biological and the mental. The reflex arc theory was reconstructed into an interactive loop of perception, feeling, thinking, and behavior, and joined with the selective interest of consciousness to become the basis of radical empiricism. Mead’s theory of the emergence of self and mind in social acts and Dewey’s analyses of the individual and society influenced the human sciences. Dewey’s theory of education as community-oriented, based on the psychological developmental stages of growth, and directed toward full participation in a democratic society, was the philosophical basis of progressive education. 

praxis from Grecian prasso, ‘doing’, ‘acting’, in Aristotle, the sphere of thought and action that comprises the ethical and political life of man, contrasted with the theoretical designs of logic and epistemology theoria. It was thus that ‘praxis’ acquired its general definition of ‘practice’ through a contrastive comparison with ‘theory’. Throughout the history of Western philosophy the concept of praxis found a place in a variety of philosophical vocabularies. Marx and the neoMarxists linked the concept with a production paradigm in the interests of historical explanation. Within such a scheme of things the activities constituting the relations of production and exchange are seen as the dominant features of the socioeconomic history of humankind. Significations of ‘praxis’ are also discernible in the root meaning of pragma deed, affair, which informed the development of  pragmatism. In more recent times the notion of praxis has played a prominent role in the formation of the school of critical theory, in which the performatives of praxis are seen to be more directly associated with the entwined phenomena of discourse, communication, and social practices. The central philosophical issues addressed in the current literature on praxis have to do with the theorypractice relationship and the problems associated with a value-free science. The general thrust is that of undermining or subverting the traditional bifurcation of theory and practice via a recognition of praxis-oriented endeavors that antedate both theory construction and the construal of practice as a mere application of theory. Both the project of “pure theory,” which makes claims for a value-neutral standpoint, and the purely instrumentalist understanding of practice, as itself shorn of discernment and insight, are jettisoned. The consequent philosophical task becomes that of understanding human thought and action against the backdrop of the everyday communicative endeavors, habits, and skills, and social practices that make up our inheritance in the world.  Praxis school, a school of philosophy originating in Zagreb and Belgrade which, from 4 to 4, published the international edition of the leading postwar Marxist journal Praxis. During the same period, it organized the Korcula Summer School, which attracted scholars from around the Western world. In a reduced form the school continues each spring with the Social Philosophy Course in Dubrovnik, Croatia. The founders of praxis philosophy include Gajo Petrovic Zagreb, Milan Kangrga Zagreb, and Mihailo Markovic Belgrade. Another wellknown member of the group is Svetozar Stojanovic Belgrade, and a second-generation leader is Gvozden Flego Zagreb. The Praxis school emphasized the writings of the young Marx while subjecting dogmatic Marxism to one of its strongest criticisms. Distinguishing between Marx’s and Engels’s writings and emphasizing alienation and a dynamic concept of the human being, it contributed to a greater understanding of the interrelationship between the individual and society. Through its insistence on Marx’s call for a “ruthless critique,” the school stressed open inquiry and freedom of speech in both East and West. Quite possibly the most important and original philosopher of the group, and certainly Croatia’s leading twentieth-century philosopher, was Gajo Petrovic 793. He called for 1 understanding philosophy as a radical critique of all existing things, and 2 understanding human beings as beings of praxis and creativity. This later led to a view of human beings as revolutionary by nature. At present he is probably best remembered for his Marx in the Mid-Twentieth Century and Philosophie und Revolution. Milan Kangrga b.3 also emphasizes human creativity while insisting that one should understand human beings as producers who humanize nature. An ethical problematic of humanity can pragmatism, ethical Praxis school 731    731 be realized through a variety of disciplines that include aesthetics, philosophical anthropolgy, theory of knowledge, ontology, and social thought. Mihailo Markovic b.3, a member of the Belgrade Eight, is best known for his theory of meaning, which leads him to a theory of socialist humanism. His most widely read work in the West is From Affluence to Praxis: Philosophy and Social Criticism. 

Pre-analytic, considered but naive; commonsensical; not tainted by prior explicit theorizing; said of judgments and, derivatively, of beliefs or intuitions underlying such judgments. Preanalytic judgments are often used to test philosophical theses. All things considered, we prefer theories that accord with preanalytic judgments to those that do not, although most theorists exhibit a willingness to revise preanalytic assessments in light of subsequent inquiry. Thus, a preanalytic judgment might be thought to constitute a starting point for the philosophical consideration of a given topic. Is justice giving every man his due? It may seem so, preanalytically. Attention to concrete examples, however, may lead us to a different view. It is doubtful, even in such cases, that we altogether abandon preanalytic judgments. Rather, we endeavor to reconcile apparently competing judgments, making adjustments in a way that optimizes overall coherence. 

praedicabile: As in qualia being the plural of quale and universalia being the plural of universale, predicabilia is Boethius’s plural for the ‘predicabile’ -- something Grice knew by heart from giving seminars at Oxfrod on Aristotle’s categories with Austin and Strawson. He found the topic boring enough to give the seminar ALONE!

prædicatum: vide Is there a praedicatum in Blackburn’s one-off predicament. He draws a skull and communicates that there is danger. The drawsing of the skull is not syntactically structured. So it is difficult to isolate the ‘praedicatum.’ That’s why Grice leaves matters of the praedicatum’ to reductive analyses at a second stage of his programme, where one wants to apply, metabolically, ‘communicate’ to what an emissum does. The emissum of the form, The S is P, predicates P of S.  Vide subjectification, and subjectum. Of especial interest to Grice and Strawson. Lewis and Short have “praedīco,” which they render as “to say or mention before or beforehand, to premise.” Grice as a modista is interested in parts of speech: nomen (onoma) versus verbum (rhema) being the classical, since Plato. The mediaeval modistae like Alcuin adapted Aristotle, and Grice follows suit. Of particular relevance are the ‘syncategoremata,’ since Grice was obsessed with particles, and we cannot say that ‘and’ is a predicate! This relates to the ‘categorema.’ Liddell and Scott have “κατηγόρ-ημα,” which they render as “accusation, charge,” Gorg.Pal.22; but in philosophy, as “predicate,” as per Arist.Int.20b32, Metaph.1053b19, etc.; -- “οὐκ εὔοδον τὸ ἁπλοῖν ἐστι κ.” Epicur.Fr.18. – and as “head of predicables,” in Arist.Metaph.1028a33,Ph.201a1,  Zeno Stoic.1.25, etc.; περὶ κατηγορημάτων Sphaer.ib.140. The term syncategorema comes from a passage of Priscian in his Institutiones grammatice II , 15. “coniunctae plenam faciunt orationem, alias autem partes, κατηγορήματα, hoc est consignificantiaappellabant.” A distinction is made between two types of word classes ("partes orationis," singular, "pars orationis") distinguished by philosophers since Plato, viz. nouns (nomen, onoma) and verbs (verbum, rhema) on the one hand, and a  'syncategorema or consignificantium. A consignificantium, just as the unary functor "non," and any of the three dyadic functors, "et," "vel" (or "aut") and "si," does not have a definitive meaning on its own -- cf. praepositio, cited by Grice, -- "the meaning of 'to,' the meaning of 'of,'" -- rather, they acquire meaning in combination or when con-joined to one or more categorema. It is one thing to say that we employ a certain part of speech when certain conditions are fulfilled and quite another to claim that the role in the language of that part of speech is to say, even in an extended sense, that those conditions are fulfilled. In Logic, the verb 'kategoreo' is 'predicate of a person or thing,' “τί τινος” Arist.Cat.3a19,al., Epicur.Fr.250; κυρίως, καταχρηστικῶς κ., Phld.Po.5.15; “ἐναντίως ὑπὲρ τῶν αὐτῶν” Id.Oec.p.60 J.: —more freq. in Pass., to be predicated of . . , τινος Arist.Cat.2a21, APr. 26b9, al.; “κατά τινος” Id.Cat.2a37; “κατὰ παντὸς ἢ μηδενός” Id.APr.24a15: less freq. “ἐπί τινος” Id.Metaph.998b16, 999a15; so later “ἐφ᾽ ἑνὸς οἴονται θεοῦ ἑκάτερον τῶν ὀνομάτων -εῖσθαι” D.H.2.48; “περί τινος” Arist.

prejudices: the life and opinions of H. P. Grice, by H. P. Grice! PGRICE had been in the works for a while. Knowing this, Grice is able to start his auto-biography, or memoir, to which he later adds a specific reply to this or that objection by the editors. The reply is divided in neat sections. After a preamble displaying his gratitude for the volume in his honour, Grice turns to his prejudices and predilections; which become, the life and opinions of H. P. Grice. The third section is a reply to the editorss overview of his work. This reply itself is itself subdivided into questions of meaning and rationality, and questions of Met. , philosophical psychology, and value. As the latter is repr. in “Conception” it is possible to cite this sub-section from the Reply as a separate piece. Grice originally entitles his essay in a brilliant manner, echoing the style of an English non-conformist, almost: Prejudices and predilections; which become, the life and opinions of H. P. Grice. With his Richards, a nice Welsh surNames, Grice is punning on the first Names of both Grandy and Warner. Grice is especially concerned with what Richards see as an ontological commitment on Grices part to the abstract, yet poorly individuated entity of a proposition. Grice also deals with the alleged insufficiency in his conceptual analysis of reasoning. He brings for good measure a point about a potential regressus ad infinitum in his account of a chain of intentions involved in meaning that p and communicating that p. Even if one of the drafts is titled festschrift, not by himself, this is not strictly a festschrift in that Grices Names is hidden behind the acronym: PGRICE. Notably on the philosophy of perception. Also in “Conception,” especially that tricky third lecture on a metaphysical foundation for objective value. Grice is supposed to reply to the individual contributors, who include Strawson, but does not. I cancelled the implicaturum! However, we may identify in his oeuvre points of contacts of his own views with the philosophers who contributed, notably Strawson. Most of this material is reproduced verbatim, indeed, as the second part of his Reply to Richards, and it is a philosophical memoir of which Grice is rightly proud. The life and opinions are, almost in a joke on Witters, distinctly separated. Under Life, Grice convers his conservative, irreverent rationalism making his early initial appearance at Harborne under the influence of his non-conformist father, and fermented at his tutorials with Hardie at Corpus, and his associations with Austins play group on Saturday mornings, and some of whose members he lists alphabetically: Austin, Gardiner, Grice, Hampshire, Hare, Hart, Nowell-Smith, Paul, Pears, Strawson, Thomson, Urmson, and Warnock.  Also, his joint philosophising with Austin, Pears, Strawson, Thomson, and Warnock. Under Opinions, Grice expands mainly on ordinary-language philosophy and his Bunyanesque way to the City of Eternal Truth. Met. , Philosophical Psychology, and Value, in “Conception,” is thus part of his Prejudices and predilections. The philosophers Grice quotes are many and varied, such as Bosanquet and Kneale, and from the other place, Keynes. Grice spends some delightful time criticising the critics of ordinary-language philosophy such as Bergmann (who needs an English futilitarian?) and Gellner. He also quotes from Jespersen, who was "not a philosopher but wrote a philosophy of grammar!" And Grice includes a reminiscence of the bombshells brought from Vienna by the enfant terrible of Oxford philosophy Freddie Ayer, after being sent to the Continent by Ryle. He recalls an air marshal at a dinner with Strawson at Magdalen relishing on Cook Wilsons adage, What we know we know. And more besides! After reminiscing for Clarendon, Grice will go on to reminisce for Harvard University Press in the closing section of the Retrospective epilogue.

prelatum -- anaphora: a device of reference or cross-reference in which a term called an anaphor, typically a pronoun, has its semantic properties determined by a term or noun phrase called the anaphor’s antecedent that occurs earlier. Sometimes the antecedent is a proper name or other independently referring expression, as in ‘Jill went up the hill and then she came down again’. In such cases, the anaphor refers to the same object as its antecedent. In other cases, the anaphor seems to function as a variable bound by an antecedent quantifier, as in ‘If any miner bought a donkey, he is penniless’. But anaphora is puzzling because not every example falls neatly into one of these two groups. Thus, in ‘John owns some sheep and Harry vaccinates them’ an example due to Gareth Evans the anaphor is arguably not bound by its antecedent ‘some sheep’. And in ‘Every miner who owns a donkey beats it’ a famous type of case discovered by Geach, the anaphor is arguably neither bound by ‘a donkey’ nor a uniquely referring expression.

Praedicabile, also praedicabilia, sometimes called the quinque voces five words, in medieval philosophy, genus, species, difference, proprium, and accident, the five main ways general predicates can be predicated. The list comes from Porphyry’s Isagoge. It was debated whether it applies to linguistic predicates only or also to extralinguistic universals. Things that have accidents can exist without them; other predicables belong necessarily to whatever has them. The Aristotelian/Porphyrian notion of “inseparable accident” blurs this picture. Genus and species are natural kinds; other predicables are not. A natural kind that is not a narrowest natural kind is a genus; one that is not a broadest natural kind is a species. Some genera are also species. A proprium is not a species, but is coextensive with one. A difference belongs necessarily to whatever has it, but is neither a natural kind nor coextensive with one. 

Pre-existence, existence of the individual soul or psyche prior to its current embodiment, when the soul or psyche is taken to be separable and capable of existing independently from its embodiment. The current embodiment is then often described as a reincarnation of the soul. Plato’s Socrates refers to such a doctrine several times in the dialogues, notably in the myth of Er in Book X of the Republic. The doctrine is distinguished from two other teachings about the soul: creationism, which holds that the individual human soul is directly created by God, and traducianism, which held that just as body begets body in biological generation, so the soul of the new human being is begotten by the parental soul. In Hinduism, the cycle of reincarnations represents the period of estrangement and trial for the soul or Atman before it achieves release moksha.

prescriptivism, the theory that evaluative judgments necessarily have prescriptive meaning. Associated with noncognitivism and moral antirealism, prescriptivism holds that moral language is such that, if you say that you think one ought to do a certain kind of act, and yet you are not committed to doing that kind of act in the relevant circumstances, then you either spoke insincerely or are using the word ‘ought’ in a less than full-blooded sense. Prescriptivism owes its stature to Hare. One of his innovations is the distinction between “secondarily evaluative” and “primarily evaluative” words. The prescriptive meaning of secondarily evaluative words, such as ‘soft-hearted’ or ‘chaste’, may vary significantly while their descriptive meanings stay relatively constant. Hare argues the reverse for the primarily evaluative words ‘good’, ‘bad’, ‘right’, ‘wrong’, ‘ought’, and ‘must’. For example, some people assign to ‘wrong’ the descriptive meaning ‘forbidden by God’, others assign it the descriptive meaning ‘causes social conflict’, and others give it different descriptive meanings; but since all use ‘wrong’ with the same prescriptive meaning, they are using the same concept. In part to show how moral judgments can be prescriptive and yet have the same logical relations as indicative sentences, Hare distinguished between phrastics and neustics. The phrastic, or content, can be the same in indicative and prescriptive sentences; e.g., ‘Sam’s leaving’ is the phrastic not only of the indicative ‘Sam will leave’ but also of the prescription ‘Sam ought to leave’. Hare’s Language of Morals 2 specified that the neustic indicates mood, i.e., whether the sentence is indicative, imperative, interrogative, etc. However, in an article in Mind 9 and in Sorting Out Ethics 7, he used ‘neustic’ to refer to the sign of subscription, and ‘tropic’ to refer to the sign of mood. Prescriptivity is especially important if moral judgments are universalizable. For then we can employ golden rulestyle moral reasoning. 

pre-Socratics: cf. pre-Griceians. the early Grecian philosophers who were not influenced by Socrates. Generally they lived before Socrates, but some are contemporary with him or even younger. The classification though not the term goes back to Aristotle, who saw Socrates’ humanism and emphasis on ethical issues as a watershed in the history of philosophy. Aristotle rightly noted that philosophers prior to Socrates had stressed natural philosophy and cosmology rather than ethics. He credited them with discovering material principles and moving causes of natural events, but he criticized them for failing to stress structural elements of things formal causes and values or purposes final causes. Unfortunately, no writing of any pre-Socratic survives in more than a fragmentary form, and evidence of their views is thus often indirect, based on reports or criticisms of later writers. In order to reconstruct pre-Socratic thought, scholars have sought to collect testimonies of ancient sources and to identify quotations from the preSocratics in those sources. As modern research has revealed flaws in the interpretations of ancient witnesses, it has become a principle of exegesis to base reconstructions of their views on the actual words of the pre-Socratics themselves wherever possible. Because of the fragmentary and derivative nature of our evidence, even basic principles of a philosopher’s system sometimes remain controversial; nevertheless, we can say that thanks to modern methods of historiography, there are many points we understand better than ancient witnesses who are our secondary sources. Our best ancient secondary source is Aristotle, who lived soon after the pre-Socratics and had access to most of their writings. He interprets his predecessors from the standpoint of his own theory; but any historian must interpret philosophers in light of some theoretical background. Since we have extensive writings of Aristotle, we  understand his system and can filter out his own prejudices. His colleague Theophrastus was the first professional historian of philosophy. Adopting Aristotle’s general framework, he systematically discussed pre-Socratic theories. Unfortunately his work itself is lost, but many fragments and summaries of parts of it remain. Indeed, virtually all ancient witnesses writing after Theophrastus depend on him for their general understanding of the early philosophers, sometimes by way of digests of his work. When biography became an important genre in later antiquity, biographers collected facts, anecdotes, slanders, chronologies often based on crude a priori assumptions, lists of book titles, and successions of school directors, which provide potentially valuable information. By reconstructing ancient theories, we can trace the broad outlines of pre-Socratic development with some confidence. The first philosophers were the Milesians, philosophers of Miletus on the Ionian coast of Asia Minor, who in the sixth century B.C. broke away from mythological modes of explanation by accounting for all phenomena, even apparent prodigies of nature, by means of simple physical hypotheses. Aristotle saw the Milesians as material monists, positing a physical substrate  of water, or the apeiron, or air; but their material source was probably not a continuing substance that underlies all changes as Aristotle thought, but rather an original stuff that was transformed into different stuffs. Pythagoras migrated from Ionia to southern Italy, founding a school of Pythagoreans who believed that souls transmigrated and that number was the basis of all reality. Because Pythagoras and his early followers did not publish anything, it is difficult to trace their development and influence in detail. Back in Ionia, Heraclitus criticized Milesian principles because he saw that if substances changed into one another, the process of transformation was more important than the substances that appeared in the cycle of changes. He thus chose the unstable substance fire as his material principle and stressed the unity of opposites. Parmenides and the Eleatic School criticized the notion of notbeing that theories of physical transformations seemed to presuppose. One cannot even conceive of or talk of not-being; hence any conception that presupposes not-being must be ruled out. But the basic notions of coming-to-be, differentiation, and indeed change in general presuppose not-being, and thus must be rejected. Eleatic analysis leads to the further conclusion, implicit in Parmenides, explicit in Melissus, that there is only one substance, what-is. Since this substance does not come into being or change in any way, nor does it have any internal differentiations, the world is just a single changeless, homogeneous individual. Parmenides’ argument seems to undermine the foundations of natural philosophy. After Parmenides philosophers who wished to continue natural philosophy felt compelled to grant that coming-to-be and internal differentiation of a given substance were impossible. But in order to accommodate natural processes, they posited a plurality of unchanging, homogeneous elements  the four elements of Empedocles, the elemental stuffs of Anaxagoras, the atoms of Democritus  that by arrangement and rearrangement could produce the cosmos and the things in it. There is no real coming-to-be and perishing in the world since the ultimate substances are everlasting; but some limited kind of change such as chemical combination or mixture or locomotion could account for changing phenomena in the world of experience. Thus the “pluralists” incorporated Eleatic principles into their systems while rejecting the more radical implications of the Eleatic critique. Pre-Socratic philosophers developed more complex systems as a response to theoretical criticisms. They focused on cosmology and natural philosophy in general, championing reason and nature against mythological traditions. Yet the pre-Socratics have been criticized both for being too narrowly scientific in interest and for not being scientific experimental enough. While there is some justice in both criticisms, their interests showed breadth as well as narrowness, and they at least made significant conceptual progress in providing a framework for scientific and philosophical ideas. While they never developed sophisticated theories of ethics, logic, epistemology, or metaphysics, nor invented experimental methods of confirmation, they did introduce the concepts that ultimately became fundamental in modern theories of cosmic, biological, and cultural evolution, as well as in atomism, genetics, and social contract theory. Because the Socratic revolution turned philosophy in different directions, the pre-Socratic line died out. But the first philosophers supplied much inspiration for the sophisticated fourthcentury systems of Plato and Aristotle as well as the basic principles of the great Hellenistic schools, Epicureanism, Stoicism, and Skepticism. 

presupposition, 1 a relation between sentences or statements, related to but distinct from entailment and assertion; 2 what a speaker takes to be understood in making an assertion. The first notion is semantic, the second pragmatic. The semantic notion was introduced by Strawson in his attack on Russell’s theory of descriptions, and perhaps anticipated by Frege. Strawson argued that ‘The present king of France is bald’ does not entail ‘There is a present king of France’ as Russell held, but instead presupposes it. Semantic presupposition can be defined thus: a sentence or statement S presupposes a sentence or statement SH provided S entails SH and the negation of S also entails SH . SH is a condition of the truth or falsity of S. Thus, since ‘There is a present king of France’ is false, ‘The present king of France is bald’ is argued to be neither true nor false. So construed, presupposition is defined in terms of, but is distinct from, entailment. It is also distinct from assertion, since it is viewed as a precondition of the truth or falsity of what is asserted. The pragmatic conception does not appeal to truth conditions, but instead contrasts what a speaker presupposes and what that speaker asserts in making an utterance. Thus, someone who utters ‘The present king of France is bald’ presupposes  believes and believes that the audience believes  that there is a present king of France, and asserts that this king is bald. So conceived, presuppositions are beliefs that the speaker takes for granted; if these beliefs are false, the utterance will be inappropriate in some way, but it does not follow that the sentence uttered lacks a truth-value. These two notions of presupposition are logically independent. On the semantic characterization, presupposition is a relation between sentences or statements requiring that there be truth-value gaps. On the pragmatic characterization, it is speakers rather than sentences or statements that have presuppositions; no truth-value gaps are required. Many philosophers and linguists have argued for treating what have been taken to be cases of semantic presupposition, including the one discussed above, as pragmatic phenomena. Some have denied that semantic presuppositions exist. If not, intuitions about presupposition do not support the claims that natural languages have truth-value gaps and that we need a three-valued logic to represent the semantics of natural language adequately. Presupposition is also distinct from implicaturum. If someone reports that he has just torn his coat and you say, “There’s a tailor shop around the corner,” you conversationally implicate that the shop is open. This is not a semantic presupposition because if it is false that the shop is open, there is no inclination to say that your assertion was neither true nor false. It is not a pragmatic presupposition because it is not something you believe the hearer believes.

pretheoretical, independent of theory. More specifically, a proposition is pretheoretical, according to some philosophers, if and only if it does not depend for its plausibility or implausibility on theoretical considerations or considerations of theoretical analysis. The term ‘preanalytic’ is often used synonymously with ‘pretheoretical’, but the former is more properly paired with analysis rather than with theory. Some philosophers characterize pretheoretical propositions as “intuitively” plausible or implausible. Such propositions, they hold, can regulate philosophical theorizing as follows: in general, an adequate philosophical theory should not conflict with intuitively plausible propositions by implying intuitively implausible propositions, and should imply intuitively plausible propositions. Some philosophers grant that theoretical considerations can override “intuitions”  in the sense of intuitively plausible propositions  when overall theoretical coherence or reflective equilibrium is thereby enhanced. 

prescriptum: prescriptivism. According to Grice’s prescriptive meta-ethics, by uttering ‘p,’ the emissor may intend his recipient to entertain a desiderative state of content ‘p.’ In which case, the emissor is ‘prescribing’ a course of conduct. As opposed to the ‘descriptum,’ which just depicts a ‘state’ of affairs that the emissor wants to inform his recipient about.  Surely there are for Grice at least two different modes, the buletic, which tends towards the prescriptive, and the doxastic, which is mostly ‘descriptive.’ One has to be careful because Grice thinks that what a philosopher like Strawson does with ‘descriptive’ expression (like ‘true,’ ‘know’ and ‘good’) and talk of pseudo-descriptive. What is that gives the buletic a ‘prescritive’ or deontic ring to it? This is Kant’s question. Grice kept a copy of Foots on morality as a system of hypothetical imperatives. “So Somervillian Oxonian it hurts!”. Grice took virtue ethics more seriously than the early Hare. Hare will end up a virtue ethicist, since he changed from a meta-ethicist to a moralist embracing a hedonistic version of eudaemonist utilitarianism. Grice was more Aristotelianly conservative! Unlike Hares and Grices meta-ethical sensitivities (as members of the Oxonian school of ordinary-language philosophy), Foot suggests a different approach to ethics. Grice admired Foots ability to make the right conceptual distinction. Foot is following a very Oxonian tradition best represented by the work of Warnock. Of course, Grice was over-familiar with the virtue vs. vice distinction, since Hardie had instilled it on him at Corpus! For Grice, virtue and vice (and the mesotes), display an interesting logical grammar, though. Grice would say that rationality is a virtue; fallacious reasoning is a vice. Some things Grice takes more of a moral standpoint about. To cheat is neither irrational nor unreasonble: just plain repulsive.  As such, it would be a vice ‒ mind not getting caught in its grip! Grice is concerned with vice in his account of akrasia or incontinentia. If agent A KNOWS that doing x is virtuous, yet decides to do ~x, which is vicious, A is being akratic. For Grice, akratic behaviour applies both in the buletic or boulomaic realm and in the doxastic realm. And it is part of the philosopher’s job to elucidate the conceptual intricacies attached to it. 1. prima-facie (p!q) V probably (pq). 2. prima-facie ((A and B) !p) V probably ( (A and B) p). 3. prima-facie ((A and B and C) !p) V probably ( (A and B and C,) p). 4. prima-facie ((all things before P V!p) V probably ((all things before P)  p). 5. prima-facie ((all things are considered  !p) V probably (all things are considered,  p). 6. !q V .q 7.

Price: Welsh Dissenting minister, actuary, and moral philosopher. His main work, A Review of the Principal Question in Morals 1758, is a defense of rationalism in ethics. He argued that the understanding immediately perceives simple, objective, moral qualities of actions. The resulting intuitive knowledge of moral truths is accompanied by feelings of approval and disapproval responsible for moral motivation. He also wrote influential papers on life expectancy, public finance, and annuities; communicated to the Royal Society the paper by his deceased friend Thomas Bayes containing Bayes’s theorem; and defended the  and  revolutions. Burke’s Reflections on the Revolution in France is a response to one of Price’s sermons.

Prichard: h. a. – H. P. Grice called himself a neo-Prichardian, but then “I used to be a neo-Stoutian before that!” -- English philosopher and founder of the Oxford school of intuitionism. An Oxford fellow and professor, he published Kant’s Theory of Knowledge 9 and numerous essays, collected in Moral Obligation 9, 8 and in Knowledge and Perception 0. Prichard was a realist in his theory of knowledge, following Cook Wilson. He held that through direct perception in concrete cases we obtain knowledge of universals and of necessary connections between them, and he elaborated a theory about our knowledge of material objects. In “Does Moral Philosophy Rest on a Mistake?” 2 he argued powerfully that it is wrong to think that a general theory of obligation is possible. No single principle captures the various reasons why obligatory acts are obligatory. Only by direct perception in particular cases can we see what we ought to do. With this essay Prichard founded the Oxford school of intuitionism, carried on by, among others, Ross.

Priestley, J.: British philosopher. In 1774 he prepared oxygen by heating mercuric oxide. Although he continued to favor the phlogiston hypothesis, his work did much to discredit that idea. He discovered many gases, including ammonia, sulfur dioxide, carbon monoxide, and hydrochloric acid. While studying the layer of carbon dioxide over a brewing vat, he conceived the idea of dissolving it under pressure. The resulting “soda water” was famous throughout Europe. His Essay on Government 1768 influenced Jefferson’s ideas in the  Declaration of Independence. The essay also contributed to the utilitarianism of Bentham, supplying the phrase “the greatest happiness of the greatest number.” Priestley modified the associationism of Locke, Hume, and Hartley, holding that a sharp distinction must be drawn between the results of association in forming natural propensities and its effects on the development of moral ideas. On the basis of this distinction, he argued, against Hume, that differences in individual moral sentiments are results of education, through the association of ideas, a view anticipated by Helvétius. Priestley served as minister to anti-Establishment congregations. His unpopular stress on individual freedom resulted in his move to Pennsylvania, where he spent his last years.

Primum -- prime mover, the original source and cause of motion change in the universe  an idea that was developed by Aristotle and became important in Judaic, Christian, and Islamic thought about God. According to Aristotle, something that is in motion a process of change is moving from a state of potentiality to a state of actuality. For example, water that is being heated is potentially hot and in the process of becoming actually hot. If a cause of change must itself actually be in the state that it is bringing about, then nothing can produce motion in itself; whatever is in motion is being moved by another. For otherwise something would be both potentially and actually in the same state. Thus, the water that is potentially hot can become hot only by being changed by something else the fire that is actually hot. The prime mover, the original cause of motion, must itself, therefore, not be in motion; it is an unmoved mover. Aquinas and other theologians viewed God as the prime mover, the ultimate cause of all motion. Indeed, for these theologians the argument to establish the existence of a first mover, itself unmoved, was a principal argument used in their efforts to prove the existence of God on the basis of reason. Many modern thinkers question the argument for a first mover on the ground that it does not seem to be logically impossible that the motion of one thing be caused by a second thing whose motion in turn is caused by a third thing, and so on without end. Defenders of the argument claim that it presupposes a distinction between two different causal series, one temporal and one simultaneous, and argue that the objection succeeds only against a temporal causal series.  PRIMA PHILOSOPHIA -- first philosophy, in Aristotle’s Metaphysics, the study of being qua being, including the study of theology as understood by him, since the divine is being par excellence. Descartes’s Meditations on First Philosophy was concerned chiefly with the existence of God, the immortality of the soul, and the nature of matter and of the mind.

Prince Maurice’s parrot: The ascription of ‘that’-clause in the report of a communicatum by a pirot of stage n-1 may be a problem by a priot in stage n. Do we want to say that the parrot communicates that he finds Prince Maurice an idiot? While some may not be correct that Griciean principles can be explained on practical, utilitarian grounds, Grice’s main motivation is indeed to capture the ‘rational’ capacity. Since I think I may be confident, that, whoever should see a creature of his own shape or make, though it had no more reason all its life than a cat or a parrot, would call him still a man; or whoever should hear a cat or a parrot discourse, reason, and philosophize, would call or think it nothing but a cat or a parrot; and say, the one was a dull irrational man, and the other a very intelligent rational parrot. A relation we have in an author of great note, is sufficient to countenance the supposition of a rational parrot. His words are: "I had a mind to know, from Prince Maurice's own mouth, the account of a common, but much credited story, that I had heard so often from many others, of an old parrot he had in Brazil, during his government there, that spoke, and asked, and answered common questions, like a reasonable creature: so that those of his train there generally concluded it to be witchery or possession; and one of his chaplains, who lived long afterwards in Holland, would never from that time endure a parrot, but said they all had a devil in them. I had heard many particulars of this story, and as severed by people hard to be discredited, which made me ask Prince Maurice what there was of it. He said, with his usual plainness and dryness in talk, there was something true, but a great deal false of what had been reported. I desired to know of him what there was of the first. He told me short and coldly, that he had heard of such an old parrot when he had been at Brazil; and though he believed nothing of it, and it was a good way off, yet he had so much curiosity as to send for it: that it was a very great and a very old one; and when it came first into the room where the prince was, with a great many Dutchmen about him, it said presently, What a company of white men are here! They asked it, what it thought that man was, pointing to the prince. It answered, Some General or other. When they brought it close to him, he asked it, D'ou venez-vous? It answered, De Marinnan. The Prince, A qui estes-vous? The Parrot, A un Portugais. The Prince, Que fais-tu la? Parrot, Je garde les poulles. The Prince laughed, and said, Vous gardez les poulles? The Parrot answered, Oui, moi; et je scai bien faire; and made the chuck four or five times that people use to make to chickens when they call them. I set down the words of this worthy dialogue in French, just as Prince Maurice said them to me. I asked him in what language the parrot spoke, and he said in Brazilian. I asked whether he understood Brazilian; he said No, but he had taken care to have two interpreters by him, the one a Dutchman that spoke Brazilian, and the other a Brazilian that spoke Dutch; that he asked them separately and privately, and both of them agreed in telling him just the same thing that the parrot had said. I could not but tell this odd story, because it is so much out of the way, and from the first hand, and what may pass for a good one; for I dare say this Prince at least believed himself in all he told me, having ever passed for a very honest and pious man: I leave it to naturalists to reason, and to other men to believe, as they please upon it; however, it is not, perhaps, amiss to relieve or enliven a busy scene sometimes with such digressions, whether to the purpose or no." I have taken care that the reader should have the story at large in the author's own words, because he seems to me not to have thought it incredible; for it cannot be imagined that so able a man as he, who had sufficiency enough to warrant all the testimonies he gives of himself, should take so much pains, in a place where it had nothing to do, to pin so close, not only on a man whom he mentions as his friend, but on a Prince in whom he acknowledges very great honesty and piety, a story which, if he himself thought incredible, he could not but also think ridiculous. The Prince, it is plain, who vouches this story, and our author, who relates it from him, both of them call this talker a parrot: and I ask any one else who thinks such a story fit to be told, whether, if this parrot, and all of its kind, had always talked, as we have a prince's word for it this one did,- whether, I say, they would not have passed for a race of rational animals; but yet, whether, for all that, they would have been allowed to be men, and not parrots? For I presume it is not the idea of a thinking or rational being alone that makes the idea of a man in most people's sense: but of a body, so and so shaped, joined to it: and if that be the idea of a man, the same successive body not shifted all at once, must, as well as the same immaterial spirit, go to the making of the same man.

Principle: a philosopher loves a principle. principium. Grice. Principle of conversational helpfulness. “I call it ‘principle,’ echoing Boethius.”Mention should also he made of Boethius’ conception, that there are certain principles, sentences which have no demonstration — probatio — which he calls principales propositiones or probationis principia. Here is the fragment from his Commentary on Topics treating of principles; El iliac quidem (propositiones) quarum nulla probatio est, maximae ac principales vocantur, quod his illas necesse est approbari, quae ut demonstrari valeant, non recusant/ est auteni maxima proposiiio ut liaec « si de aequalibus aequalia demas, quae derelinquitur aequalia sunt », ita enim hoc per se notion est, ut aliud notius quo approbari valeat esse non possit; quae proposi- tiones cum (idem sui natura propria gerant, non solum alieno ad (idem non egent argumento, oerum ceteris quoque probationis sclent esse principium; igitur per se notae propositiones, quibus nihil est notius, indemonstrabiles ac maxime et principales vocantur (“Indeed those sentences that have no demonstration are called maximum or principal [sentences], because they are not rejected since they are necessary to those that have to be demonstrated and which are valid for making a demonstration ; but a maximum sentence such as « if from equal [quantifies], equal [quantities] are taken, what is left are equal [quantities]*, is self- evident, and there is nothing which can be better known self-evidently valid, and self- demonstrating, therefore they are sentences containing their certitude in their very nature and not only do they need no additional argument to demonstrate their certitude, but are also the principles of demonstration of the other [sentences]; so they are, self-evident sen- tences, nothing being better known than they are, and are called undemonstrable or maxi- mum and principal”). Boethius’ idea coincides with Aristotle’s; deduction must start from somewhere, we must begin with something unproved. The Stagirite, how- ever, gave an explanation of the existence of principles and the possibility of their being grasjied by the active intellect, whereas with Boethius princi- ples appear as severed from the sentences demonstrated in a more formal manner: there are two kinds of sentences: some which are demonstrable and others which need no demonstration There’s the principle of economy of rational effort: (principium oeconomiae effortis rationalis). Cf. his metaphor of the hamburger. Grice knew that ‘economy’ is vague. It relates to the ‘open house.’ But is a crucial concept. It is not the principle of parsimony of rational effort. It is not the principle of ‘minimisaation’ of rational effort. It is the principle of the ‘economy’ of rational effort. ‘Economy’ is already a value-oriented word, since it is a branch of politics and meta-ethics. oecŏnŏmĭcus , a, um, adj., = οἰκονομικός. I.

The skull complete with the rest of the body will not do. So abiding by this principle has nothing to do with an arbitrary convention. Vide principle of least conversational effort. Principle of conversational least effort. No undue effort (candour), no unnecessary trouble (self-love) if doing A involves too much conversational effort, never worry: you will be DEEMED to have made the effort. Invoked by Grice in “Prejudices and predilections; which become, the life and opinions of H. P. Grice.” When Grice qualifies this as ‘rational’ effort, what other efforts are there? Note that the lexeme ‘effort’ does NOT feature in the formulation of the principle itself. Grice confesses to be strongly inclined to assent to the principle of economy of rational conversational effort or the principle of economy of conversational effort, or the principle of economy of conversational expenditure, or the principle of minimisation of rational expenditure, or the principle of minimization of conversational expenditure, or the principle of minimisation of rational cost, or the conversational maximin. The principle of least cost. The principle of economy of rational expenditure states that, where there is a ratiocinative procedure for arriving rationally at certain outcome, a procedure which, because it is ratiocinative, involves an expenditure of time and energy, if there is a NON-ratiocinative, and so more economical procedure which is likely, for the most part, to reach the same outcome as the ratiocinative procedure, provided the stakes are not too high, it is rational to employ the cheaper though somewhat less reliable non-ratiocinative procedure as a substitute for ratiocination. Grice thinks this principle would meet with genitorial approval, in which case the genitor would install it for use should opportunity arise. This applies to the charge of overcomplexity and ‘psychological irreality’ of the reasoning involved in the production and design of the maximally efficient conversational move and the reasoning involved in the recognition of the implicaturum by the addressee. In “Epilogue” he goes by yet another motto, Do not multiply rationalities beyond necessity: The principle of conversational rationality, as he calls it in the Epilogue, is a sub-principle of a principle of rationality simpiciter, not applying to a pursuit related to ‘communication,’ as he puts it. Then there’s the principium individuationis, the cause or basis of individuality in individuals; what makes something individual as opposed to universal, e.g., what makes the cat Minina individual and thus different from the universal, cat. Questions regarding the principle of individuation were first raised explicitly in the early Middle Ages. Classical authors largely ignored individuation; their ontological focus was on the problem of universals. The key texts that originated the discussion of the principle of individuation are found in Boethius. Between Boethius and 1150, individuation was always discussed in the context of more pressing issues, particularly the problem of universals. After 1150, individuation slowly emerged as a focus of attention, so that by the end of the thirteenth century it had become an independent subject of discussion, especially in Aquinas and Duns Scotus. Most early modern philosophers conceived the problem of individuation epistemically rather than metaphysically; they focused on the discernibility of individuals rather than the cause of individuation, as in Descartes. With few exceptions, such as Karl Popper, the twentieth century has followed this epistemic approach e. g. P. F. Strawson.  principle of bivalence, the principle that any significant statement is either true or false. It is often confused with the principle of excluded middle. Letting ‘Tp’ stand for ‘p is true’ and ‘Tp’ for ‘p is false’ and otherwise using standard logical notation, bivalence is ‘Tp 7 T-p’ and excluded middle is ‘T p 7 -p’. That they are different principles is shown by the fact that in probability theory, where ‘Tp’ can be expressed as ‘Prp % 1’, bivalence ‘Pr p % 1 7 Pr ~p % 1’ is not true for all values of p  e.g. it is not true where ‘p’ stands for ‘given a fair toss of a fair die, the result will be a six’ a statement with a probability of 1 /6, where -p has a probability of 5 /6  but excluded middle ‘Prp 7 -p % 1’ is true for all definite values of p, including the probability case just given. If we allow that some significant statements have no truth-value or probability and distinguish external negation ‘Tp’ from internal negation ‘T-p’, we can distinguish bivalence and excluded middle from the principle of non-contradiction, namely, ‘-Tp • T-p’, which is equivalent to ‘-Tp 7 -T-p’. Standard truth-functional logic sees no difference between ‘p’ and ‘Tp’, or ‘-Tp’ and ‘T-p’, and thus is unable to distinguish the three principles. Some philosophers of logic deny there is such a difference. principle of contradiction, also called principle of non-contradiction, the principle that a statement and its negation cannot both be true. It can be distinguished from the principle of bivalence, and given certain controversial assumptions, from the principle of excluded middle; but in truth-functional logic all three are regarded as equivalent. Outside of formal logic the principle of non-contradiction is best expressed as Aristotle expresses it: “Nothing can both be and not be at the same time in the same respect.”  principle of double effect, the view that there is a morally relevant difference between those consequences of our actions we intend and those we do not intend but do still foresee. According to the principle, if increased literacy means a higher suicide rate, those who work for education are not guilty of driving people to kill themselves. A physician may give a patient painkillers foreseeing that they will shorten his life, even though the use of outright poisons is forbidden and the physician does not intend to shorten the patient’s life. An army attacking a legitimate military target may accept as inevitable, without intending to bring about, the deaths of a number of civilians. Traditional moral theologians affirmed the existence of exceptionless prohibitions such as that against taking an innocent human life, while using the principle of double effect to resolve hard cases and avoid moral blind alleys. They held that one may produce a forbidden effect, provided 1 one’s action also had a good effect, 2 one did not seek the bad effect as an end or as a means, 3 one did not produce the good effect through the bad effect, and 4 the good effect was important enough to outweigh the bad one. Some contemporary philosophers and Roman Catholic theologians hold that a modified version of the principle of double effect is the sole justification of deadly deeds, even when the person killed is not innocent. They drop any restriction on the causal sequence, so that e.g. it is legitimate to cut off the head of an unborn child to save the mother’s life. But they oppose capital punishment on the ground that those who inflict it require the death of the convict as part of their plan. They also play down the fourth requirement, on the ground that the weighing of incommensurable goods it requires is impossible. Consequentialists deny the principle of double effect, as do those for whom the crucial distinction is between what we cause by our actions and what just happens. In the most plausible view, the principle does not presuppose exceptionless moral prohibitions, only something stronger than prima facie duties. It is easier to justify an oblique evasion of a moral requirement than a direct violation, even if direct violations are sometimes permissible. So understood, the principle is a guide to prudence rather than a substitute for it.  principle of excluded middle, the principle that the disjunction of any significant statement with its negation is always true; e.g., ‘Either there is a tree over 500 feet tall or it is not the case that there is such a tree’. The principle is often confused with the principle of bivalence. principle of indifference, a rule for assigning a probability to an event based on “parity of reasons.” According to the principle, when the “weight of reasons” favoring one event is equal to the “weight of reasons” favoring another, the two events should be assigned the same probability. When there are n mutually exclusive and collectively exhaustive events, and there is no reason to favor one over another, then we should be “indifferent” and the n events should each be assigned probability 1/n the events are equiprobable, according to the principle. This principle is usually associated with the names Bernoulli Ars Conjectandi, 1713 and Laplace Théorie analytique des probabilités, 1812, and was so called by J. M. Keynes A Treatise on Probability, 1. The principle gives probability both a subjective “degree of belief” and a logical “partial logical entailment” interpretation. One rationale for the principle says that in ignorance, when no reasons favor one event over another, we should assign equal probabilities. It has been countered that any assignment of probabilities at all is a claim to some knowledge. Also, several seemingly natural applications of the principle, involving non-linearly related variables, have led to some mathematical contradictions, known as Bertrand’s paradox, and pointed out by Keynes.  principle of insufficient reason, the principle that if there is no sufficient reason or explanation for something’s being the case, then it will not be the case. Since the rise of modern probability theory, many have identified the principle of insufficient reason with the principle of indifference a rule for assigning a probability to an event based on “parity of reasons”. The two principles are closely related, but it is illuminating historically and logically to view the principle of insufficient reason as the general principle stated above which is related to the principle of sufficient reason and to view the principle of indifference as a special case of the principle of insufficient reason applying to probabilities. As Mach noted, the principle of insufficient reason, thus conceived, was used by Archimedes to argue that a lever with equal weights at equal distances from a central fulcrum would not move, since if there is no sufficient reason why it should move one way or the other, it would not move one way or the other. Philosophers from Anaximander to Leibniz used the same principle to argue for various metaphysical theses. The principle of indifference can be seen to be a special case of this principle of insufficient reason applying to probabilities, if one reads the principle of indifference as follows: when there are N mutually exclusive and exhaustive events and there is no sufficient reason to believe that any one of them is more probable than any other, then no one of them is more probable than any other they are equiprobable. The idea of “parity of reasons” associated with the principle of indifference is, in such manner, related to the idea that there is no sufficient reason for favoring one outcome over another. This is significant because the principle of insufficient reason is logically equivalent to the more familiar principle of sufficient reason if something is [the case], then there is a sufficient reason for its being [the case]  which means that the principle of indifference is a logical consequence of the principle of sufficient reason. If this is so, we can understand why so many were inclined to believe the principle of indifference was an a priori truth about probabilities, since it was an application to probabilities of that most fundamental of all alleged a priori principles of reasoning, the principle of sufficient reason. Nor should it surprise us that the alleged a priori truth of the principle of indifference was as controversial in probability theory as was the alleged a priori truth of the principle of sufficient reason in philosophy generally.  principle of plenitude, the principle that every genuine possibility is realized or actualized. This principle of the “fullness of being” was named by A. O. Lovejoy, who showed that it was commonly assumed throughout the history of Western science and philosophy, from Plato to Plotinus who associated it with inexhaustible divine productivity, through Augustine and other medieval philosophers, to the modern rationalists Spinoza and Leibniz and the Enlightenment. Lovejoy connected plenitude to the great chain of being, the idea that the universe is a hierarchy of beings in which every possible form is actualized. In the eighteenth century, the principle was “temporalized”: every possible form of creature would be realized  not necessarily at all times  but at some stage “in the fullness of time.” A clue about the significance of plenitude lies in its connection to the principle of sufficient reason everything has a sufficient reason [cause or explanation] for being or not being. Plenitude says that if there is no sufficient reason for something’s not being i.e., if it is genuinely possible, then it exists  which is logically equivalent to the negative version of sufficient reason: if something does not exist, then there is a sufficient reason for its not being. principle of verifiability, a claim about what meaningfulness is: at its simplest, a sentence is meaningful provided there is a method for verifying it. Therefore, if a sentence has no such method, i.e., if it does not have associated with it a way of telling whether it is conclusively true or conclusively false, then it is meaningless. The purpose for which this verificationist principle was originally introduced was to demarcate sentences that are “apt to make a significant statement of fact” from “nonsensical” or “pseudo-” sentences. It is part of the emotive theory of content, e.g., that moral discourse is not literally, cognitively meaningful, and therefore, not factual. And, with the verifiability principle, the central European logical positivists of the 0s hoped to strip “metaphysical discourse” of its pretensions of factuality. For them, whether there is a reality external to the mind, as the realists claim, or whether all reality is made up of “ideas” or “appearances,” as idealists claim, is a “meaningless pseudo-problem.” The verifiability principle proved impossible to frame in a form that did not admit all metaphysical sentences as meaningful. Further, it casts doubt on its own status. How was it to be verified? So, e.g., in the first edition of Language, Truth and Logic, Ayer proposed that a sentence is verifiable, and consequently meaningful, if some observation sentence can be deduced from it in conjunction with certain other premises, without being deducible from those other premises alone. It follows that any metaphysical sentence M is meaningful since ‘if M, then O’ always is an appropriate premise, where O is an observation sentence. In the preface to the second edition, Ayer offered a more sophisticated account: M is directly verifiable provided it is an observation sentence or it entails, in conjunction with certain observation sentences, some observation sentence that does not follow from them alone. And M is indirectly verifiable provided it entails, in conjunction with certain other premises, some directly verifiable sentence that does not follow from those other premises alone and these additional premises are either analytic or directly verifiable or are independently indirectly verifiable. The new verifiability principle is then that all and only sentences directly or indirectly verifiable are “literally meaningful.” Unfortunately, Ayer’s emendation admits every nonanalytic sentence. Let M be any metaphysical sentence and O1 and O2 any pair of observation sentences logically independent of each other. Consider sentence A: ‘either O1 or not-M and not-O2’. Conjoined with O2, A entails O1. But O2 alone does not entail O1. So A is directly verifiable. Therefore, since M conjoined with A entails O1, which is not entailed by A alone, M is indirectly verifiable. Various repairs have been attempted; none has succeeded.  principle of economy of rational effort -- cheapest-cost avoider, in the economic analysis of law, the party in a dispute that could have prevented the dispute, or minimized the losses arising from it, with the lowest loss to itself. The term encompasses several types of behavior. As the lowest-cost accident avoider, it is the party that could have prevented the accident at the lowest cost. As the lowest-cost insurer, it is the party that could been have insured against the losses arising from the dispute. This could be the party that could have purchased insurance at the lowest cost or self-insured, or the party best able to appraise the expected losses and the probability of the occurrence. As the lowest-cost briber, it is the party least subject to transaction costs. This party is the one best able to correct any legal errors in the assignment of the entitlement by purchasing the entitlement from the other party. As the lowest-cost information gatherer, it is the party best able to make an informed judgment as to the likely benefits and costs of an action.  Principle of economy of rational effort: Coase theorem, a non-formal insight by R. Coase: 1: assuming that there are no transaction costs involved in exchanging rights for money, then no matter how rights are initially distributed, rational agents will buy and sell them so as to maximize individual returns. In jurisprudence this proposition has been the basis for a claim about how rights should be distributed even when as is usual transaction costs are high: the law should confer rights on those who would purchase them were they for sale on markets without transaction costs; e.g., the right to an indivisible, unsharable resource should be conferred on the agent willing to pay the highest price for it. 

prisoner’s dilemma, a problem in game theory, and more broadly the theory of rational choice, that takes its name from a familiar sort of pleabargaining situation: Two prisoners Robin and Carol are interrogated separately and offered the same deal: If one of them confesses “defects” and the other does not, the defector will be given immunity from prosecution and the other will get a stiff prison sentence. If both confess, both will get moderate prison terms. If both remain silent cooperate with each other, both will get light prison terms for a lesser offense. There are thus four possible outcomes: 1 Robin confesses and gets immunity, while Carol is silent and gets a stiff sentence. 2 Both are silent and get light sentences. 3 Both confess and get moderate sentences. 4 Robin is silent and gets a stiff sentence, while Carol confesses and gets immunity. Assume that for Robin, 1 would be the best outcome, followed by 2, 3, and 4, in that order. Assume that for Carol, the best outcome is 4, followed by 2, 3, and 1. Each prisoner then reasons as follows: “My confederate will either confess or remain silent. If she confesses, I must do likewise, in order to avoid the ‘sucker’s payoff’ immunity for her, a stiff sentence for me. If she remains silent, then I must confess in order to get immunity  the best outcome for me. Thus, no matter what my confederate does, I must confess.” Under those conditions, both will confess, effectively preventing each other from achieving anything better than the option they both rank as only third-best, even though they agree that option 2 is second-best. This illustrative story attributed to A. W. Tucker must not be allowed to obscure the fact that many sorts of social interactions have the same structure. In general, whenever any two parties must make simultaneous or independent choices over a range of options that has the ordinal payoff structure described in the plea bargaining story, they are in a prisoner’s dilemma. Diplomats, negotiators, buyers, and sellers regularly find themselves in such situations. They are called iterated prisoner’s dilemmas if the same parties repeatedly face the same choices with each other. Moreover, there are analogous problems of cooperation and conflict at the level of manyperson interactions: so-called n-person prisoner’s diemmas or free rider problems. The provision of public goods provides an example. Suppose there is a public good, such as clean air, national defense, or public radio, which we all want. Suppose that is can be provided only by collective action, at some cost to each of the contributors, but that we do not have to have a contribution from everyone in order to get it. Assume that we all prefer having the good to not having it, and that the best outcome for each of us would be to have it without cost to ourselves. So each of us reasons as follows: “Other people will either contribute enough to produce the good by themselves, or they will not. If they do, then I can have it cost-free the best option for me and thus I should not contribute. But if others do not contribute enough to produce the good by themselves, and if the probability is very low that my costly contribution would make the difference between success and failure, once again I should not contribute.” Obviously, if we all reason in this way, we will not get the public good we want. Such problems of collective action have been noticed by philosophers since Plato. Their current nomenclature, rigorous game-theoretic formulation, empirical study, and systematic philosophical development, however, has occurred since 0. 

private language argument, an argument designed to show that there cannot be a language that only one person can speak  a language that is essentially private, that no one else can in principle understand. In addition to its intrinsic interest, the private language argument is relevant to discussions of linguistic rules and linguistic meaning, behaviorism, solipsism, and phenomenalism. The argument is closely associated with Vitters’s Philosophical Investigations 8. The exact structure of the argument is controversial; this account should be regarded as a standard one, but not beyond dispute. The argument begins with the supposition that a person assigns signs to sensations, where these are taken to be private to the person who has them, and attempts to show that this supposition cannot be sustained because no standards for the correct or incorrect application of the same sign to a recurrence of the same sensation are possible. Thus Vitters supposes that he undertakes to keep a diary about the recurrence of a certain sensation; he associates it with the sign ‘S’, and marks ‘S’ on a calendar every day he has that sensation. Vitters finds the nature of the association of the sign and sensation obscure, on the ground that ‘S’ cannot be given an ordinary definition this would make its meaning publicly accessible or even an ostensive definition. He further argues that there is no difference between correct and incorrect entries of ‘S’ on subsequent days. The initial sensation with which the sign ‘S’ was associated is no longer present, and so it cannot be compared with a subsequent sensation taken to be of the same kind. He could at best claim to remember the nature of the initial sensation, and judge that it is of the same kind as today’s. But since the memory cannot confirm its own accuracy, there is no possible test of whether he remembers the initial association of sign and sensation right today. Consequently there is no criterion for the correct reapplication of the sign ‘S’. Thus we cannot make sense of the notion of correctly reapplying ‘S’, and cannot make sense of the notion of a private language. The argument described appears to question only the claim that one could have terms for private mental occurrences, and may not seem to impugn a broader notion of a private language whose expressions are not restricted to signs for sensations. Advocates of Vitters’s argument would generalize it and claim that the focus on sensations simply highlights the absence of a distinction between correct and incorrect reapplications of words. A language with terms for publicly accessible objects would, if private to its user, still be claimed to lack criteria for the correct reapplication of such terms. This broader notion of a private language would thus be argued to be equally incoherent. 

privation: H. P. Grice, “Negation and privation,” a lack of something that it is natural or good to possess. The term is closely associated with the idea that evil is itself only a lack of good, privatio boni. In traditional theistic religions everything other than God is created by God out of nothing, creation ex nihilo. Since, being perfect, God would create only what is good, the entire original creation and every creature from the most complex to the simplest are created entirely good. The original creation contains no evil whatever. What then is evil and how does it enter the world? The idea that evil is a privation of good does not mean, e.g., that a rock has some degree of evil because it lacks such good qualities as consciousness and courage. A thing has some degree of evil only if it lacks some good that is    741 privileged access privileged access 742 proper for that thing to possess. In the original creation each created thing possessed the goods proper to the sort of thing it was. According to Augustine, evil enters the world when creatures with free will abandon the good above themselves for some lower, inferior good. Human beings, e.g., become evil to the extent that they freely turn from the highest good God to their own private goods, becoming proud, selfish, and wicked, thus deserving the further evils of pain and punishment. One of the problems for this explanation of the origin of evil is to account for why an entirely good creature would use its freedom to turn from the highest good to a lesser good. 

privileged access: H. P. Grice, “Privileged access and incorrigibility,” special first-person awareness of the contents of one’s own mind. Since Descartes, many philosophers have held that persons are aware of the occurrent states of their own minds in a way distinct from both their mode of awareness of physical objects and their mode of awareness of the mental states of others. Cartesians view such apprehension as privileged in several ways. First, it is held to be immediate, both causally and epistemically. While knowledge of physical objects and their properties is acquired via spatially intermediate causes, knowledge of one’s own mental states involves no such causal chains. And while beliefs about physical properties are justified by appeal to ways objects appear in sense experience, beliefs about the properties of one’s own mental states are not justified by appeal to properties of a different sort. I justify my belief that the paper on which I write is white by pointing out that it appears white in apparently normal light. By contrast, my belief that white appears in my visual experience seems to be self-justifying. Second, Cartesians hold that first-person apprehension of occurrent mental contents is epistemically privileged in being absolutely certain. Absolute certainty includes infallibility, incorrigibility, and indubitability. That a judgment is infallible means that it cannot be mistaken; its being believed entails its being true even though judgments regarding occurrent mental contents are not necessary truths. That it is incorrigible means that it cannot be overridden or corrected by others or by the subject himself at a later time. That it is indubitable means that a subject can never have grounds for doubting it. Philosophers sometimes claim also that a subject is omniscient with regard to her own occurrent mental states: if a property appears within her experience, then she knows this. Subjects’ privileged access to the immediate contents of their own minds can be held to be necessary or contingent. Regarding corrigibility, for example, proponents of the stronger view hold that first-person reports of occurrent mental states could never be overridden by conflicting evidence, such as conflicting readings of brain states presumed to be correlated with the mental states in question. They point out that knowledge of such correlations would itself depend on first-person reports of mental states. If a reading of my brain indicates that I am in pain, and I sincerely claim not to be, then the law linking brain states of that type with pains must be mistaken. Proponents of the weaker view hold that, while persons are currently the best authorities as to the occurrent contents of their own minds, evidence such as conflicting readings of brain states could eventually override such authority, despite the dependence of the evidence on earlier firstperson reports. Weaker views on privileged access may also deny infallibility on more general grounds. In judging anything, including an occurrent mental state, to have a particular property P, it seems that I must remember which property P is, and memory appears to be always fallible. Even if such judgments are always fallible, however, they may be more immediately justified than other sorts of judgments. Hence there may still be privileged access, but of a weaker sort. In the twentieth century, Ryle attacked the idea of privileged access by analyzing introspection, awareness of what one is thinking or doing, in terms of behavioral dispositions, e.g. dispositions to give memory reports of one’s mental states when asked to do so. But while behaviorist or functional analyses of some states of mind may be plausible, for instance analyses of cognitive states such as beliefs, accounts in these terms of occurrent states such as sensations or images are far less plausible. A more influential attack on stronger versions of privileged access was mounted by Wilfrid Sellars. According to him, we must be trained to report non-inferentially on properties of our sense experience by first learning to respond with whole systems of concepts to public, physical objects. Before I can learn to report a red sense impression, I must learn the system of color concepts and the logical relations among them by learning to respond to colored objects. Hence, knowledge of my own mental states cannot be the firm basis from which I progress to other knowledge.  Even if this order of concept acquisition is determined necessarily, it still may be that persons’ access to their own mental states is privileged in some of the ways indicated, once the requisite concepts have been acquired. Beliefs about one’s own occurrent states of mind may still be more immediately justified than beliefs about physical properties, for example. 

pro attitude, a favorable disposition toward an object or state of affairs. Although some philosophers equate pro attitudes with desires, the expression is more often intended to cover a wide range of conative states of mind including wants, feelings, wishes, values, and principles. My regarding a certain course of action open to me as morally required and my regarding it as a source of selfish satisfaction equally qualify as pro attitudes toward the object of that action. It is widely held that intentional action, or, more generally, acting for reasons, is necessarily based, in part, on one or more pro attitudes. If I go to the store in order to buy some turnips, then, in addition to my regarding my store-going as conducive to turnip buying, I must have some pro attitude toward turnip buying. 

Probabile: probability -- doomsday argument, an argument examined by Grice -- an argument associated chiefly with the mathematician Brandon Carter and the philosopher John Leslie purporting to show, by appeal to Bayes’s theorem and Bayes’s rule, that whatever antecedent probability we may have assigned to the hypothesis that human life will end relatively soon is magnified, perhaps greatly, upon our learning or noticing that we are among the first few score thousands of millions of human beings to exist.Leslie’s The End of the World: The Science and Ethics of Human Extinction 6. The argument is based on an allegedly close analogy between the question of the probability of imminent human extinction given our ordinal location in the temporal swath of humanity and the fact that the reader’s name being among the first few drawn randomly from an urn may greatly enhance for the reader the probability that the urn contains fairly few names rather than very many.  probability, a numerical value that can attach to items of various kinds e.g., propositions, events, and kinds of events that is a measure of the degree to which they may or should be expected  or the degree to which they have “their own disposition,” i.e., independently of our psychological expectations  to be true, to occur, or to be exemplified depending on the kind of item the value attaches to. There are both multiple interpretations of probability and two main kinds of theories of probability: abstract formal calculi and interpretations of the calculi. An abstract formal calculus axiomatically characterizes formal properties of probability functions, where the arguments of the function are often thought of as sets, or as elements of a Boolean algebra. In application, the nature of the arguments of a probability function, as well as the meaning of probability, are given by interpretations of probability. The most famous axiomatization is Kolmogorov’s Foundations of the Theory of Probability, 3. The three axioms for probability functions Pr are: 1 PrX M 0 for all X; 2 PrX % 1 if X is necessary e.g., a tautology if a proposition, a necessary event if an event, and a “universal set” if a set; and 3 PrX 7 Y % PrX ! PrY where ‘7’ can mean, e.g., logical disjunction, or set-theoretical union if X and Y are mutually exclusive X & Y is a contradiction if they are propositions, they can’t both happen if they are events, and their set-theoretical intersection is empty if they are sets. Axiom 3 is called finite additivity, which is sometimes generalized to countable additivity, involving infinite disjunctions of propositions, or infinite unions of sets. Conditional probability, PrX/Y the probability of X “given” or “conditional on” Y, is defined as the quotient PrX & Y/PrY. An item X is said to be positively or negatively statistically or probabilistically correlated with an item Y according to whether PrX/Y is greater than or less than PrX/-Y where -Y is the negation of a proposition Y, or the non-occurrence of an event Y, or the set-theoretical complement of a set Y; in the case of equality, X is said to be statistically or probabilistically independent of Y. All three of these probabilistic relations are symmetric, and sometimes the term ‘probabilistic relevance’ is used instead of ‘correlation’. From the axioms, familiar theorems can be proved: e.g., 4 Pr-X % 1  PrX; 5 PrX 7 Y % PrX ! PrY  PrX & Y for all X and Y; and 6 a simple version of Bayes’s theorem PrX/Y % PrY/XPrX/PrY. Thus, an abstract formal calculus of probability allows for calculation of the probabilities of some items from the probabilities of others. The main interpretations of probability include the classical, relative frequency, propensity, logical, and subjective interpretations. According to the classical interpretation, the probability of an event, e.g. of heads on a coin toss, is equal to the ratio of the number of “equipossibilities” or equiprobable events favorable to the event in question to the total number of relevant equipossibilities. On the relative frequency interpretation, developed by Venn The Logic of Chance, 1866 and Reichenbach The Theory of Probability, probability attaches to sets of events within a “reference class.” Where W is the reference class, and n is the number of events in W, and m is the number of events in or of kind X, within W, then the probability of X, relative to W, is m/n. For various conceptual and technical reasons, this kind of “actual finite relative frequency” interpretation has been refined into various infinite and hypothetical infinite relative frequency accounts, where probability is defined in terms of limits of series of relative frequencies in finite nested populations of increasing sizes, sometimes involving hypothetical infinite extensions of an actual population. The reasons for these developments involve, e.g.: the artificial restriction, for finite populations, of probabilities to values of the form i/n, where n is the size of the reference class; the possibility of “mere coincidence” in the actual world, where these may not reflect the true physical dispositions involved in the relevant events; and the fact that probability is often thought to attach to possibilities involving single events, while probabilities on the relative frequency account attach to sets of events this is the “problem of the single case,” also called the “problem of the reference class”. These problems also have inspired “propensity” accounts of probability, according to which probability is a more or less primitive idea that measures the physical propensity or disposition of a given kind of physical situation to yield an outcome of a given type, or to yield a “long-run” relative frequency of an outcome of a given type. A theorem of probability proved by Jacob Bernoulli Ars Conjectandi, 1713 and sometimes called Bernoulli’s theorem or the weak law of large numbers, and also known as the first limit theorem, is important for appreciating the frequency interpretation. The theorem states, roughly, that in the long run, frequency settles down to probability. For example, suppose the probability of a certain coin’s landing heads on any given toss is 0.5, and let e be any number greater than 0. Then the theorem implies that as the number of tosses grows without bound, the probability approaches 1 that the frequency of heads will be within e of 0.5. More generally, let p be the probability of an outcome O on a trial of an experiment, and assume that this probability remains constant as the experiment is repeated. After n trials, there will be a frequency, f n, of trials yielding outcome O. The theorem says that for any numbers d and e greater than 0, there is an n such that the probability P that _pf n_ ‹ e is within d of 1 P  1d. Bernoulli also showed how to calculate such n for given values of d, e, and p. It is important to notice that the theorem concerns probabilities, and not certainty, for a long-run frequency. Notice also the assumption that the probability p of O remains constant as the experiment is repeated, so that the outcomes on trials are probabilistically independent of earlier outcomes. The kinds of interpretations of probability just described are sometimes called “objective” or “statistical” or “empirical” since the value of a probability, on these accounts, depends on what actually happens, or on what actual given physical situations are disposed to produce  as opposed to depending only on logical relations between the relevant events or propositions, or on what we should rationally expect to happen or what we should rationally believe. In contrast to these accounts, there are the “logical” and the “subjective” interpretations of probability. Carnap “The Two Concepts of Probability,” Philosophy and Phenomenological Research, 5 has marked this kind of distinction by calling the second concept probability1 and the first probability2. According to the logical interpretation, associated with Carnap  Logical Foundations of Probability, 0; and Continuum of Inductive Methods, 2, the probability of a proposition X given a proposition Y is the “degree to which Y logically entails X.” Carnap developed an ingenious and elaborate set of systems of logical probability, including, e.g., separate systems depending on the degree to which one happens to be, logically and rationally, sensitive to new information in the reevaluation of probabilities. There is, of course, a connection between the ideas of logical probability, rationality, belief, and belief revision. It is natural to explicate the “logical-probabilistic” idea of the probability of X given Y as the degree to which a rational person would believe X having come to learn Y taking account of background knowledge. Here, the idea of belief suggests a subjective sometimes called epistemic or partial belief or degree of belief interpretation of probability; and the idea of probability revision suggests the concept of induction: both the logical and the subjective interpretations of probability have been called “inductive probability”  a formal apparatus to characterize rational learning from experience. The subjective interpretation of probability, according to which the probability of a proposition is a measure of one’s degree of belief in it, was developed by, e.g., Ramsey “Truth and Probability,” in his Foundations of Mathematics and Other Essays, 6; Definetti “Foresight: Its Logical Laws, Its Subjective Sources,” 7, translated by H. Kyburg, Jr., in H. E. Smokler, Studies in Subjective Probability, 4; and Savage The Foundations of Statistics, 4. Of course, subjective probability varies from person to person. Also, in order for this to be an interpretation of probability, so that the relevant axioms are satisfied, not all persons can count  only rational, or “coherent” persons should count. Some theorists have drawn a connection between rationality and probabilistic degrees of belief in terms of dispositions to set coherent betting odds those that do not allow a “Dutch book”  an arrangement that forces the agent to lose come what may, while others have described the connection in more general decision-theoretic terms. 

problem of induction. First stated by Hume, this problem concerns the logical basis of inferences from observed matters of fact to unobserved matters of fact. Although discussion often focuses upon predictions of future events e.g., a solar eclipse, the question applies also to inferences to past facts e.g., the extinction of dinosaurs and to present occurrences beyond the range of direct observation e.g., the motions of planets during daylight hours. Long before Hume the ancient Skeptics had recognized that such inferences cannot be made with certainty; they realized there can be no demonstrative deductive inference, say, from the past and present to the future. Hume, however, posed a more profound difficulty: Are we justified in placing any degree of confidence in the conclusions of such inferences? His question is whether there is any type of non-demonstrative or inductive inference in which we can be justified in placing any confidence at all. According to Hume, our inferences from the observed to the unobserved are based on regularities found in nature. We believe, e.g., that the earth, sun, and moon move in regular patterns according to Newtonian mechanics, and on that basis astronomers predict solar and lunar eclipses. Hume notes, however, that all of our evidence for such uniformities consists of past and present experience; in applying these uniformities to the future behavior of these bodies we are making an inference from the observed to the unobserved. This point holds in general. Whenever we make inferences from the observed to the unobserved we rely on the uniformity of nature. The basis for our belief that nature is reasonably uniform is our experience of such uniformity in the past. If we infer that nature will continue to be uniform in the future, we are making an inference from the observed to the unobserved  precisely the kind of inference for which we are seeking a justification. We are thus caught up in a circular argument. Since, as Hume emphasized, much of our reasoning from the observed to the unobserved is based on causal relations, he analyzed causality to ascertain whether it could furnish a necessary connection between distinct events that could serve as a basis for such inferences. His conclusion was negative. We cannot establish any such connection a priori, for it is impossible to deduce the nature of an effect from its cause  e.g., we cannot deduce from the appearance of falling snow that it will cause a sensation of cold rather than heat. Likewise, we cannot deduce the nature of a cause from its effect  e.g., looking at a diamond, we cannot deduce that it was produced by great heat and pressure. All such knowledge is based on past experience. If we infer that future snow will feel cold or that future diamonds will be produced by great heat and pressure, we are again making inferences from the observed to the unobserved. Furthermore, if we carefully observe cases in which we believe a causeeffect relation holds, we cannot perceive any necessary connection between cause and effect, or any power in the cause that brings about the effect. We observe only that an event of one type e.g., drinking water occurs prior to and contiguously with an event of another type quenching thirst. Moreover, we notice that events of the two types have exhibited a constant conjunction; i.e., whenever an event of the first type has occurred in the past it has been followed by one of the second type. We cannot discover any necessary connection or causal power a posteriori; we can only establish priority, contiguity, and constant conjunction up to the present. If we infer that this constant conjunction will persist in future cases, we are making another inference from observed to unobserved cases. To use causality as a basis for justifying inference from the observed to the unobserved would again invovle a circular argument. Hume concludes skeptically that there can be no rational or logical justification of inferences from the observed to the unobserved  i.e., inductive or non-demonstrative inference. Such inferences are based on custom and habit. Nature has endowed us with a proclivity to extrapolate from past cases to future cases of a similar kind. Having observed that events of one type have been regularly followed by events of another type, we experience, upon encountering a case of the first type, a psychological expectation that one of the second type will follow. Such an expectation does not constitute a rational justification. Although Hume posed his problem in terms of homely examples, the issues he raises go to the heart of even the most sophisticated empirical sciences, for all of them involve inference from observed phenomena to unobserved facts. Although complex theories are often employed, Hume’s problem still applies. Its force is by no means confined to induction by simple enumeration. Philosophers have responded to the problem of induction in many different ways. Kant invoked synthetic a priori principles. Many twentieth-century philosophers have treated it as a pseudo-problem, based on linguistic confusion, that requires dissolution rather than solution. Carnap maintained that inductive intuition is indispensable. Reichenbach offered a pragmatic vindication. Goodman has recommended replacing Hume’s “old riddle” with a new riddle of induction that he has posed. Popper, taking Hume’s skeptical arguments as conclusive, advocates deductivism. He argues that induction is unjustifiable and dispensable. None of the many suggestions is widely accepted as correct.  problem of the criterion, a problem of epistemology, arising in the attempt both to formulate the criteria and to determine the extent of knowledge. Skeptical and non-skeptical philosophers disagree as to what, or how much, we know. Do we have knowledge of the external world, other minds, the past, and the future? Any answer depends on what the correct criteria of knowledge are. The problem is generated by the seeming plausibility of the following two propositions: 1 In order to recognize instances, and thus to determine the extent, of knowledge, we must know the criteria for it. 2 In order to know the criteria for knowledge i.e., to distinguish between correct and incorrect criteria, we must already be able to recognize its instances. According to an argument of ancient Grecian Skepticism, we can know neither the extent nor the criteria of knowledge because 1 and 2 are both true. There are, however, three further possibilities. First, it might be that 2 is true but 1 false: we can recognize instances of knowledge even if we do not know the criteria of knowledge. Second, it might be that 1 is true but 2 false: we can identify the criteria of knowledge without prior recognition of its instances. Finally, it might be that both 1 and 2 are false. We can know the extent of knowledge without knowing criteria, and vice versa. Chisholm, who has devoted particular attention to this problem, calls the first of these options particularism, and the second methodism. Hume, a skeptic about the extent of empirical knowledge, was a methodist. Reid and Moore were particularists; they rejected Hume’s skepticism on the ground that it turns obvious cases of knowledge into cases of ignorance. Chisholm advocates particularism because he believes that, unless one knows to begin with what ought to count as an instance of knowledge, any choice of a criterion is ungrounded and thus arbitrary. Methodists turn this argument around: they reject as dogmatic any identification of instances of knowledge not based on a criterion.  problem of the speckled hen: a problem propounded by Ryle as an objection to Ayer’s analysis of perception in terms of sense-data. It is implied by this analysis that, if I see a speckled hen in a good light and so on, I do so by means of apprehending a speckled sense-datum. The analysis implies further that the sense-datum actually has just the number of speckles that I seem to see as I look at the hen, and that it is immediately evident to me just how many speckles this is. Thus, if I seem to see many speckles as I look at the hen, the sense-datum I apprehend must actually contain many speckles, and it must be immediately evident to me how many it does contain. Now suppose it seems to me that I see more than 100 speckles. Then the datum I am apprehending must contain more than 100 speckles. Perhaps it contains 132 of them. The analysis would then imply, absurdly, that it must be immediately evident to me that the number of speckles is exactly 132. One way to avoid this implication would be to deny that a sense-datum of mine could contain exactly 132 speckles  or any other large, determinate number of them  precisely on the ground that it could never seem to me that I was seeing exactly that many speckles. A possible drawback of this approach is that it involves committing oneself to the claim, which some philosophers have found problem of the criterion problem of the speckled hen 747    747 self-contradictory, that a sense-datum may contain many speckles even if there is no large number n such that it contains n speckles. 

prolatum – participle for ‘proferre,’ to utter. A much better choice than Austin’s pig-latin “utteratum”! Grice prefferd Latinate when going serious. While the verb is ‘profero – the participle corresponds to the ‘implicaturum’: what the emissor profers. profer (v.)c. 1300, "to utter, express," from Old French proferer (13c.) "utter, present verbally, pronounce," from Latin proferre "to bring forth, produce," figuratively "make known, publish, quote, utter." Sense confused with proffer. Related: Proferedprofering.
process-product ambiguity, an ambiguity that occurs when a noun can refer either to a process or activity or to the product of that process or activity. E.g., ‘The definition was difficult’ could mean either that the activity of defining was a difficult one to perform, or that the definiens the form of words proposed as equivalent to the term being defined that the definer produced was difficult to understand. Again, ‘The writing absorbed her attention’ leaves it unclear whether it was the activity of writing or a product of that activity that she found engrossing. Philosophically significant terms that might be held to exhibit processproduct ambiguity include: ‘analysis’, ‘explanation’, ‘inference’, ‘thought’. P.Mac. process theology, any theology strongly influenced by the theistic metaphysics of Whitehead or Hartshorne; more generally, any theology that takes process or change as basic characteristics of all actual beings, including God. Those versions most influenced by Whitehead and Hartshorne share a core of convictions that constitute the most distinctive theses of process theology: God is constantly growing, though certain abstract features of God e.g., being loving remain constant; God is related to every other actual being and is affected by what happens to it; every actual being has some self-determination, and God’s power is reconceived as the power to lure attempt to persuade each actual being to be what God wishes it to be. These theses represent significant differences from ideas of God common in the tradition of Western theism, according to which God is unchanging, is not really related to creatures because God is not affected by what happens to them, and has the power to do whatever it is logically possible for God to do omnipotence. Process theologians also disagree with the idea that God knows the future in all its details, holding that God knows only those details of the future that are causally necessitated by past events. They claim these are only certain abstract features of a small class of events in the near future and of an even smaller class in the more distant future. Because of their understanding of divine power and their affirmation of creaturely self-determination, they claim that they provide a more adequate theodicy. Their critics claim that their idea of God’s power, if correct, would render God unworthy of worship; some also make this claim about their idea of God’s knowledge, preferring a more traditional idea of omniscience. Although Whitehead and Hartshorne were both philosophers rather than theologians, process theology has been more influential among theologians. It is a major current in contemporary  Protestant theology and has attracted the attention of some Roman Catholic theologians as well. It also has influenced some biblical scholars who are attempting to develop a distinctive process hermeneutics.

production theory, the economic theory dealing with the conversion of factors of production into consumer goods. In capitalistic theories that assume ideal markets, firms produce goods from three kinds of factors: capital, labor, and raw materials. Production is subject to the constraint that profit the difference between revenues and costs be maximized. The firm is thereby faced with the following decisions: how much to produce, what price to charge for the product, what proportions to combine the three kinds of factors in, and what price to pay for the factors. In markets close to perfect competition, the firm will have little control over prices so the decision problem tends to reduce to the amounts of factors to use. The range of feasible factor combinations depends on the technologies available to firms. Interesting complications arise if not all firms have access to the same technologies, or if not all firms make accurate responses concerning technological changes. Also, if the scale of production affects the feasible technologies, the firms’ decision process must be subtle. In each of these cases, imperfect competition will result. Marxian economists think that the concepts used in this kind of production theory have a normative component. In reality, a large firm’s capital tends to be owned by a rather small, privileged class of non-laborers and labor is treated as a commodity like any other factor. This might lead to the perception that profit results primarily from capital and, therefore, belongs to its owners. Marxians contend that labor is primarily responsible for profit and, consequently, that labor is entitled to more than the market wage. 

professional ethics, a term designating one or more of 1 the justified moral values that should govern the work of professionals; 2 the moral values that actually do guide groups of professionals, whether those values are identified as a principles in codes of ethics promulgated by professional societies or b actual beliefs and conduct of professionals; and 3 the study of professional ethics in the preceding senses, either i normative philosophical inquiries into the values desirable for professionals to embrace, or ii descriptive scientific studies of the actual beliefs and conduct of groups of professionals. Professional values include principles of obligation and rights, as well as virtues and personal moral ideals such as those manifested in the lives of Jane Addams, Albert Schweitzer, and Thurgood Marshall. Professions are defined by advanced expertise, social organizations, society-granted monopolies over services, and especially by shared commitments to promote a distinctive public good such as health medicine, justice law, or learning education. These shared commitments imply special duties to make services available, maintain confidentiality, secure informed consent for services, and be loyal to clients, employers, and others with whom one has fiduciary relationships. Both theoretical and practical issues surround these duties. The central theoretical issue is to understand how the justified moral values governing professionals are linked to wider values, such as human rights. Most practical dilemmas concern how to balance conflicting duties. For example, what should attorneys do when confidentiality requires keeping information secret that might save the life of an innocent third party? Other practical issues are problems of vagueness and uncertainty surrounding how to apply duties in particular contexts. For example, does respect for patients’ autonomy forbid, permit, or require a physician to assist a terminally ill patient desiring suicide? Equally important is how to resolve conflicts of interest in which self-seeking places moral values at risk. 

proof by recursion, also called proof by mathematical induction, a method for conclusively demonstrating the truth of universal propositions about the natural numbers. The system of natural numbers is construed as an infinite sequence of elements beginning with the number 1 and such that each subsequent element is the immediate successor of the preceding element. The immediate successor of a number is the sum of that number with 1. In order to apply this method to show that every number has a certain chosen property it is necessary to demonstrate two subsidiary propositions often called respectively the basis step and the inductive step. The basis step is that the number 1 has the chosen property; the inductive step is that the successor of any number having the chosen property is also a number having the chosen property in other words, for every number n, if n has the chosen property then the successor of n also has the chosen property. The inductive step is itself a universal proposition that may have been proved by recursion. The most commonly used example of a theorem proved by recursion is the remarkable fact, known before the time of Plato, that the sum of the first n odd numbers is the square of n. This proposition, mentioned prominently by Leibniz as requiring and having demonstrative proof, is expressed in universal form as follows: for every number n, the sum of the first n odd numbers is n2. 1 % 12, 1 ! 3 % 22, 1 ! 3 ! 5 % 32, and so on. Rigorous formulation of a proof by recursion often uses as a premise the proposition called, since the time of De Morgan, the principle of mathematical induction: every property belonging to 1 and belonging to the successor of every number to which it belongs is a property that belongs without exception to every number. Peano took the principle of mathematical induction as an axiom in his 9 axiomatization of arithmetic or the theory of natural numbers. The first acceptable formulation of this principle is attributed to Pascal.  proof theory, a branch of mathematical logic founded by David Hilbert in the 0s to pursue Hilbert’s Program. The foundational problems underlying that program had been formulated around the turn of the century, e.g., in Hilbert’s famous address to the International Congress of Mathematicians in Paris 0. They were closely connected with investigations on the foundations of analysis carried out by Cantor and Dedekind; but they were also related to their conflict with Kronecker on the nature of mathematics and to the difficulties of a completely unrestricted notion of set or multiplicity. At that time, the central issue for Hilbert was the consistency of sets in Cantor’s sense. He suggested that the existence of consistent sets multiplicities, e.g., that of real numbers, could be secured by proving the consistency of a suitable, characterizing axiomatic system; but there were only the vaguest indications on how to do that. In a radical departure from standard practice and his earlier hints, Hilbert proposed four years later a novel way of attacking the consistency problem for theories in Über die Grundlagen der Logik und der Arithmetik 4. This approach would require, first, a strict formalization of logic together with mathematics, then consideration of the finite syntactic configurations constituting the joint formalism as mathematical objects, and showing by mathematical arguments that contradictory formulas cannot be derived. Though Hilbert lectured on issues concerning the foundations of mathematics during the subsequent years, the technical development and philosophical clarification of proof theory and its aims began only around 0. That involved, first of all, a detailed description of logical calculi and the careful development of parts of mathematics in suitable systems. A record of the former is found in Hilbert and Ackermann, Grundzüge der theoretischen Logik 8; and of the latter in Supplement IV of Hilbert and Bernays, Grundlagen der Mathematik II 9. This presupposes the clear distinction between metamathematics and mathematics introduced by Hilbert. For the purposes of the consistency program metamathematics was now taken to be a very weak part of arithmetic, so-called finitist mathematics, believed to correspond to the part of mathematics that was accepted by constructivists like Kronecker and Brouwer. Additional metamathematical issues concerned the completeness and decidability of theories. The crucial technical tool for the pursuit of the consistency problem was Hilbert’s e-calculus. The metamathematical problems attracted the collaboration of young and quite brilliant mathematicians with philosophical interests; among them were Paul Bernays, Wilhelm Ackermann, John von Neumann, Jacques Herbrand, Gerhard Gentzen, and Kurt Schütte. The results obtained in the 0s were disappointing when measured against the hopes and ambitions: Ackermann, von Neumann, and Herbrand established essentially the consistency of arithmetic with a very restricted principle of induction. That limits of finitist considerations for consistency proofs had been reached became clear in 1 through Gödel’s incompleteness theorems. Also, special cases of the decision problem for predicate logic Hilbert’s Entscheidungsproblem had been solved; its general solvability was made rather implausible by some of Gödel’s results in his 1 paper. The actual proof of unsolvability had to wait until 6 for a conceptual clarification of ‘mechanical procedure’ or ‘algorithm’; that was achieved through the work of Church and Turing. The further development of proof theory is roughly characterized by two complementary tendencies: 1 the extension of the metamathematical frame relative to which “constructive” consistency proofs can be obtained, and 2 the refined formalization of parts of mathematics in theories much weaker than set theory or even full second-order arithmetic. The former tendency started with the work of Gödel and Gentzen in 3 establishing the consistency of full classical arithmetic relative to intuitionistic arithmetic; it led in the 0s and 0s to consistency proofs of strong subsystems of secondorder arithmetic relative to intuitionistic theories of constructive ordinals. The latter tendency reaches back to Weyl’s book Das Kontinuum 8 and culminated in the 0s by showing that the classical results of mathematical analysis can be formally obtained in conservative extensions of first-order arithmetic. For the metamathematical work Gentzen’s introduction of sequent calculi and the use of transfinite induction along constructive ordinals turned out to be very important, as well as Gödel’s primitive recursive functionals of finite type. The methods and results of proof theory are playing, not surprisingly, a significant role in computer science. Work in proof theory has been motivated by issues in the foundations of mathematics, with the explicit goal of achieving epistemological reductions of strong theories for mathematical practice like set theory or second-order arithmetic to weak, philosophically distinguished theories like primitive recursive arithmetic. As the formalization of mathematics in strong theories is crucial for the metamathematical approach, and as the programmatic goal can be seen as a way of circumventing the philosophical issues surrounding strong theories, e.g., the nature of infinite sets in the case of set theory, Hilbert’s philosophical position is often equated with formalism  in the sense of Frege in his Über die Grundlagen der Geometrie 306 and also of Brouwer’s inaugural address Intuitionism and Formalism 2. Though such a view is not completely unsupported by some of Hilbert’s polemical remarks during the 0s, on balance, his philosophical views developed into a sophisticated instrumentalism, if that label is taken in Ernest Nagel’s judicious sense The Structure of Science, 1. Hilbert’s is an instrumentalism emphasizing the contentual motivation of mathematical theories; that is clearly expressed in the first chapter of Hilbert and Bernays’s Grundlagen der Mathematik I 4. A sustained philosophical analysis of proof-theoretic research in the context of broader issues in the philosophy of mathematics was provided by Bernays; his penetrating essays stretch over five decades and have been collected in Abhandlungen zur Philosophie der Mathematik 6. 

Propensum -- propensity, an irregular or non-necessitating causal disposition of an object or system to produce some result or effect. Propensities are usually conceived as essentially probabilistic in nature. A die may be said to have a propensity of “strength” or magnitude 1 /6 to turn up a 3 if thrown from a dice box, of strength 1 /3 to turn up, say, a 3 or 4, etc. But propensity talk is arguably appropriate only when determinism fails. Strength is often taken to vary from 0 to 1. Popper regarded the propensity notion as a new physical or metaphysical hypothesis, akin to that of forces. Like Peirce, he deployed it to interpret probability claims about single cases: e.g., the probability of this radium atom’s decaying in 1,600 years is 1 /2. On relative frequency interpretations, probability claims are about properties of large classes such as relative frequencies of outcomes in them, rather than about single cases. But single-case claims appear to be common in quantum theory. Popper advocated a propensity interpretation of quantum theory. Propensities also feature in theories of indeterministic or probabilistic causation. Competing theories about propensities attribute them variously to complex systems such as chance or experimental set-ups or arrangements a coin and tossing device, to entities within such set-ups the coin itself, and to particular trials of such set-ups. Long-run theories construe propensities as dispositions to give rise to certain relative frequencies of, or probability distributions over, outcomes in long runs of trials, which are sometimes said to “manifest” or “display” the propensities. Here a propensity’s strength is identical to some such frequency. By contrast, single-case theories construe propensities as dispositions of singular trials to bring about particular outcomes. Their existence, not their strength, is displayed by such an outcome. Here frequencies provide evidence about propensity strength. But the two can always differ; they converge with a limiting probability of 1 in an appropriate long run. 

propositio universalis: cf. substitutional account of universal quantification, referred to by Grice for his treatment of what he calls a Ryleian agitation caused by his feeling Byzantine. Vide inverted A. A proposition (protasis), then, is a sentence affirming or denying something of something; and this is either universal or particular or indefinite. By universal I mean a statement that something belongs to all or none of something; by particular that it belongs to some or not to some or not to all; by indefinite that it does or does not belong, without any mark of being universal or particular, e.g. ‘contraries are subjects of the same science’, or ‘pleasure is not good’. (Prior Analytics I, 1, 24a16–21.). propositional complexum: In logic, the first proposition of a syllogism (class.): “propositio est, per quem locus is breviter exponitur, ex quo vis omnis oportet emanet ratiocinationis,” Cic. Inv. 1, 37, 67; 1, 34, 35; Auct. Her. 2, 18, 28.— B. Transf. 1. A principal subject, theme (class.), Cic. de Or. 3, 53; Sen. Ben. 6, 7, 1; Quint. 5, 14, 1.— 2. Still more generally, a proposition of any kind (post-Aug.), Quint. 7, 1, 47, § 9; Gell. 2, 7, 21.—Do not expect Grice to use the phrase ‘propositional content,’ as Hare does so freely. Grices proposes a propositional complexum, rather, which frees him from a commitment to a higher-order calculus and the abstract entity of a feature or a proposition. Grice regards a proposition as an extensional family of propositional complexa (Paul saw Peter; Peter was seen by Paul). The topic of a propositional complex Grice regards as Oxonian in nature. Peacocke struggles with the same type of problems, in his essays on content. Only a perception-based account of content in terms of qualia gets the philosopher out of the vicious circle of appealing to a linguistic entity to clarify a psychological entity. One way to discharge the burden of giving an account of a proposition involves focusing on a range of utterances, the formulation of which features no connective or quantifier. Each expresses a propositional complexum which consists of a sequence simplex-1 and simplex-2, whose elements would be a set and an ordered sequence of this or that individuum which may be a member of the set. The propositional complexum ‘Fido is shaggy’ consists of a sequence of the set of shaggy individua and the singleton consisting of the individuum Fido. ‘Smith loves Fido’ is a propositional complexum, i. e., a sequence whose first element is the class “love” correlated to a two-place predicate) and a the ordered pair of the singletons Smith and Fido. We define alethic satisfactoriness. A propositional complexum is alethically satisfactory just in case the sequence is a member of the set. A “proposition” (prosthesis) simpliciter is defined as a family of propositional complexa. Family unity may vary in accordance with context.  proposition, an abstract object said to be that to which a person is related by a belief, desire, or other psychological attitude, typically expressed in language containing a psychological verb ‘think’, ‘deny’, ‘doubt’, etc. followed by a thatclause. The psychological states in question are called propositional attitudes. When I believe that snow is white I stand in the relation of believing to the proposition that snow is white. When I hope that the protons will not decay, hope relates me to the proposition that the protons will not decay. A proposition can be a common object for various attitudes of various agents: that the protons will not decay can be the object of my belief, my hope, and your fear. A sentence expressing an attitude is also taken to express the associated proposition. Because ‘The protons will not decay’ identifies my hope, it identifies the proposition to which my hope relates me. Thus the proposition can be the shared meaning of this sentence and all its synonyms, in English or elsewhere e.g., ‘die Protonen werden nicht zerfallen’. This, in sum, is the traditional doctrine of propositions. Although it seems indispensable in some form  for theorizing about thought and language, difficulties abound. Some critics regard propositions as excess baggage in any account of meaning. But unless this is an expression of nominalism, it is confused. Any systematic theory of meaning, plus an apparatus of sets or properties will let us construct proposition-like objects. The proposition a sentence S expresses might, e.g., be identified with a certain set of features that determines S’s meaning. Other sentences with these same features would then express the same proposition. A natural way to associate propositions with sentences is to let the features in question be semantically significant features of the words from which sentences are built. Propositions then acquire the logical structures of sentences: they are atomic, conditional, existential, etc. But combining the view of propositions as meanings with the traditional idea of propositions as bearers of truthvalues brings trouble. It is assumed that two sentences that express the same proposition have the same truth-value indeed, that sentences have their truth-values in virtue of the propositions they express. Yet if propositions are also meanings, this principle fails for sentences with indexical elements: although ‘I am pale’ has a single meaning, two utterances of it can differ in truth-value. In response, one may suggest that the proposition a sentence S expresses depends both on the linguistic meaning of S and on the referents of S’s indexical elements. But this reveals that proposition is a quite technical concept  and one that is not motivated simply by a need to talk about meanings. Related questions arise for propositions as the objects of propositional attitudes. My belief that I am pale may be true, yours that you are pale false. So our beliefs should take distinct propositional objects. Yet we would each use the same sentence, ‘I am pale’, to express our belief. Intuitively, your belief and mine also play similar cognitive roles. We may each choose the sun exposure, clothing, etc., that we take to be appropriate to a fair complexion. So our attitudes seem in an important sense to be the same  an identity that the assignment of distinct propositional objects hides. Apparently, the characterization of beliefs e.g. as being propositional attitudes is at best one component of a more refined, largely unknown account. Quite apart from complications about indexicality, propositions inherit standard difficulties about meaning. Consider the beliefs that Hesperus is a planet and that Phosphorus is a planet. It seems that someone might have one but not the other, thus that they are attitudes toward distinct propositions. This difference apparently reflects the difference in meaning between the sentences ‘Hesperus is a planet’ and ‘Phosphorus is a planet’. The principle would be that non-synonymous sentences express distinct propositions. But it is unclear what makes for a difference in meaning. Since the sentences agree in logico-grammatical structure and in the referents of their terms, their specific meanings must depend on some more subtle feature that has resisted definition. Hence our concept of proposition is also only partly defined. Even the idea that the sentences here express the same proposition is not easily refuted. What such difficulties show is not that the concept of proposition is invalid but that it belongs to a still rudimentary descriptive scheme. It is too thoroughly enmeshed with the concepts of meaning and belief to be of use in solving their attendant problems. This observation is what tends, through a confusion, to give rise to skepticism about propositions. One may, e.g., reasonably posit structured abstract entities  propositions  that represent the features on which the truth-values of sentences depend. Then there is a good sense in which a sentence is true in virtue of the proposition it expresses. But how does the use of words in a certain context associate them with a particular proposition? Lacking an answer, we still cannot explain why a given sentence is true. Similarly, one cannot explain belief as the acceptance of a proposition, since only a substantive theory of thought would reveal how the mind “accepts” a proposition and what it does to accept one proposition rather than another. So a satisfactory doctrine of propositions remains elusive.  propositional function, an operation that, when applied to something as argument or to more than one thing in a given order as arguments, yields a truth-value as the value of that function for that argument or those arguments. This usage presupposes that truth-values are objects. A function may be singulary, binary, ternary, etc. A singulary propositional function is applicable to one thing and yields, when so applied, a truth-value. For example, being a prime number, when applied to the number 2, yields truth; negation, when applied to truth, yields falsehood. A binary propositional function is applicable to two things in a certain order and yields, when so applied, a truth-value. For example, being north of when applied to New York and Boston in that order yields falsehood. Material implication when applied to falsehood and truth in that order yields truth. The term ‘propositional function’ has a second use, to refer to an operation that, when applied to something as argument or to more than one thing in a given order as arguments, yields a proposition as the value of the function for that argument or those arguments. For example, being a prime number when applied to 2 yields the proposition that 2 is a prime number. Being north of, when applied to New York and Boston in that order, yields the proposition that New York is north of Boston. This usage presupposes that propositions are objects. In a third use, ‘propositional function’ designates a sentence with free occurrences of variables. Thus, ‘x is a prime number’, ‘It is not the case that p’, ‘x is north of y’ and ‘if p then q’ are propositional functions in this sense. C.S. propositional justification. propositional opacity, failure of a clause to express any particular proposition especially due to the occurrence of pronouns or demonstratives. If having a belief about an individual involves a relation to a proposition, and if a part of the proposition is a way of representing the individual, then belief characterizations that do not indicate the believer’s way of representing the individual could be called propositionally opaque. They do not show all of the propositional elements. For example, ‘My son’s clarinet teacher believes that he should try the bass drum’ would be propositionally opaque because ‘he’ does not indicate how my son John’s teacher represents John, e.g. as his student, as my son, as the boy now playing, etc. This characterization of the example is not appropriate if propositions are as Russell conceived them, sometimes containing the individuals themselves as constituents, because then the propositional constituent John has been referred to. Generally, a characterization of a propositional    754 attitude is propositionally opaque if the expressions in the embedded clause do not refer to the propositional constituents. It is propositionally transparent if the expressions in the embedded clause do so refer. As a rule, referentially opaque contexts are used in propositionally transparent attributions if the referent of a term is distinct from the corresponding propositional constituent.

proprietates terminorum Latin, ‘properties of terms’, in medieval logic from the twelfth century on, a cluster of semantic properties possessed by categorematic terms. For most authors, these properties apply only when the terms occur in the context of a proposition. The list of such properties and the theory governing them vary from author to author, but always include 1 suppositio. Some authors add 2 appellatio ‘appellating’, ‘naming’, ‘calling’, often not sharply distinguishing from suppositio, the property whereby a term in a certain proposition names or is truly predicable of things, or in some authors of presently existing things. Thus ‘philosophers’ in ‘Some philosophers are wise’ appellates philosophers alive today. 3 Ampliatio ‘ampliation’, ‘broadening’, whereby a term refers to past or future or merely possible things. The reference of ‘philosophers’ is ampliated in ‘Some philosophers were wise’. 4 Restrictio ‘restriction’, ‘narrowing’, whereby the reference of a term is restricted to presently existing things ‘philosophers’ is so restricted in ‘Some philosophers are wise’, or otherwise narrowed from its normal range ‘philosophers’ in ‘Some Grecian philosophers were wise’. 5 Copulatio ‘copulation’, ‘coupling’, which is the type of reference adjectives have ‘wise’ in ‘Some philosophers are wise’, or alternatively the semantic function of the copula. Other meanings too are sometimes given to these terms, depending on the author. Appellatio especially was given a wide variety of interpretations. In particular, for Buridan and other fourteenth-century Continental authors, appellatio means ‘connotation’. Restrictio and copulatio tended to drop out of the literature, or be treated only perfunctorily, after the thirteenth century.  proprium: idion.

(14,20-31) 'Genus' and 'proprium' (ἰδίου) are said homonymously in ten ways, as are. Ackrill replies to this line of argument (75) as follows: [I]t is perfectly clear that Aristotle’s fourfold classification is a classification of things and not names, and that what is ‘said of’ something as subject is itself a thing (a species or genus) and not a name. Sometimes, indeed, Aristotle will speak of ‘saying’ or ‘predicating’ a name of a subject; but it is not linguistic items but the things they signify which are ‘said of a subject’… Thus at 2a19 ff. Aristotle sharply distinguishes things said of subjects from the names of those things. This last argument seems persuasive on textual grounds. After all, τὰ καθ᾽ ὑποκειμένου λεγόμενα ‘have’ definitions and names (τῶν καθ᾽ υποκειμένου λεγομένων… τοὔνομα καὶ τὸν λὸγον, 2a19-21): it is not the case that they ‘are’ definitions and names, to adapt the terminology of Code and Grice.152 See A. Code, ‘Aristotle: Essence and Accident’, in Grandy and Warner (eds.), Philosophical Grounds of Rationality (Oxford, 1986), 411-39: particulars have their predicables, but Forms are their predicables. Thus there is no indication that they are linguistic terms in their own right.proprium, one of Porphyry’s five predicables, often tr. as ‘property’ or ‘attribute’; but this should not be confused with the broad modern sense in which any feature of a thing may be said to be a property of it. A proprium is a nonessential peculiarity of a species. There are no propria of individuals or genera generalissima, although they may have other uniquely identifying features. A proprium necessarily holds of all members of its species and of nothing else. It is not mentioned in a real definition of the species, and so is not essential to it. Yet it somehow follows from the essence or nature expressed in the real definition. The standard example is risibility the ability to laugh as a proprium of the species man. The real definition of ‘man’ is ‘rational animal’. There is no mention of any ability to laugh. Nevertheless anything that can laugh has both the biological apparatus to produce the sounds and so is an animal and also a certain wit and insight into humor and so is rational. Conversely, any rational animal will have both the vocal chords and diaphragm required for laughing since it is an animal, although the inference may seem too quick and also the mental wherewithal to see the point of a joke since it is rational. Thus any rational animal has what it takes to laugh. In short, every man is risible, and conversely, but risibility is not an essential feature of man.  property, roughly, an attribute, characteristic, feature, trait, or aspect. propensity property 751    751 Intensionality. There are two salient ways of talking about properties. First, as predicables or instantiables. For example, the property red is predicable of red objects; they are instances of it. Properties are said to be intensional entities in the sense that distinct properties can be truly predicated of i.e., have as instances exactly the same things: the property of being a creature with a kidney & the property of being a creature with a heart, though these two sets have the same members. Properties thus differ from sets collections, classes; for the latter satisfy a principle of extensionality: they are identical if they have the same elements. The second salient way of talking about properties is by means of property abstracts such as ‘the property of being F’. Such linguistic expressions are said to be intensional in the following semantical vs. ontological sense: ‘the property of being F’ and ‘the property of being G’ can denote different properties even though the predicates ‘F’ and ‘G’ are true of exactly the same things. The standard explanation Frege, Russell, Carnap, et al. is that ‘the property of being F’ denotes the property that the predicate ‘F’ expresses. Since predicates ‘F’ and ‘G’ can be true of the same things without being synonyms, the property abstracts ‘being F’ and ‘being G’ can denote different properties. Identity criteria. Some philosophers believe that properties are identical if they necessarily have the same instances. Other philosophers hold that this criterion of identity holds only for a special subclass of properties  those that are purely qualitative  and that the properties for which this criterion does not hold are all “complex” e.g., relational, disjunctive, conditional, or negative properties. On this theory, complex properties are identical if they have the same form and their purely qualitative constituents are identical. Ontological status. Because properties are a kind of universal, each of the standard views on the ontological status of universals has been applied to properties as a special case. Nominalism: only particulars and perhaps collections of particulars exist; therefore, either properties do not exist or they are reducible following Carnap et al. to collections of particulars including perhaps particulars that are not actual but only possible. Conceptualism: properties exist but are dependent on the mind. Realism: properties exist independently of the mind. Realism has two main versions. In rebus realism: a property exists only if it has instances. Ante rem realism: a property can exist even if it has no instances. For example, the property of being a man weighing over ton has no instances; however, it is plausible to hold that this property does exist. After all, this property seems to be what is expressed by the predicate ‘is a man weighing over a ton’. Essence and accident. The properties that a given entity has divide into two disjoint classes: those that are essential to the entity and those that are accidental to it. A property is essential to an entity if, necessarily, the entity cannot exist without being an instance of the property. A property is accidental to an individual if it is possible for the individual to exist without being an instance of the property. Being a number is an essential property of nine; being the number of the planets is an accidental property of nine. Some philosophers believe that all properties are either essential by nature or accidental by nature. A property is essential by nature if it can be an essential property of some entity and, necessarily, it is an essential property of each entity that is an instance of it. The property of being self-identical is thus essential by nature. However, it is controversial whether every property that is essential to something must be essential by nature. The following is a candidate counterexample. If this automobile backfires loudly on a given occasion, loudness would seem to be an essential property of the associated bang. That particular bang could not exist without being loud. If the automobile had backfired softly, that particular bang would not have existed; an altogether distinct bang  a soft bang  would have existed. By contrast, if a man is loud, loudness is only an accidental property of him; he could exist without being loud. Loudness thus appears to be a counterexample: although it is an essential property of certain particulars, it is not essential by nature. It might be replied echoing Aristotle that a loud bang and a loud man instantiate loudness in different ways and, more generally, that properties can be predicated instantiated in different ways. If so, then one should be specific about which kind of predication instantiation is intended in the definition of ‘essential by nature’ and ‘accidental by nature’. When this is done, the counterexamples might well disappear. If there are indeed different ways of being predicated instantiated, most of the foregoing remarks about intensionality, identity criteria, and the ontological status of properties should be refined accordingly. 


prosona – Grice’s favoured spelling for ‘person’ – “seeing that it means a mask to improve sonorisation’ personalism, a Christian socialism stressing social activism and personal responsibility, the theoretical basis for the Christian workers’ Esprit movement begun in the 0s by Emmanuel Mounier 550, a Christian philosopher and activist. Influenced by both the religious existentialism of Kierkegaard and the radical social action called for by Marx and in part taking direction from the earlier work of Charles Péguy, the movement strongly opposed fascism and called for worker solidarity during the 0s and 0s. It also urged a more humane treatment of France’s colonies. Personalism allowed for a Christian socialism independent of both more conservative Christian groups and the Communist labor unions and party. Its most important single book is Mounier’s Personalism. The quarterly journal Esprit has regularly published contributions of leading  and international thinkers. Such well-known Christian philosophers as Henry Duméry, Marcel, Maritain, and Ricoeur were attracted to the movement. 

Protocol: one of the statements that constitute the foundations of empirical knowledge. The term was introduced by proponents of foundationalism, who were convinced that in order to avoid the most radical skepticism, one must countenance beliefs that are justified but not as a result of an inference. If all justified beliefs are inferentially justified, then to be justified in believing one proposition P on the basis of another, E, one would have to be justified in believing both E and that E confirms P. But if all justification were inferential, then to be justified in believing E one would need to infer it from some other proposition one justifiably believes, and so on ad infinitum. The only way to avoid this regress is to find some statement knowable without inferring it from some other truth. Philosophers who agree that empirical knowledge has foundations do not necessarily agree on what those foundations are. The British empiricists restrict the class of contingent protocol statements to propositions describing the contents of mind sensations, beliefs, fears, desires, and the like. And even here a statement describing a mental state would be a protocol statement only for the person in that state. Other philosophers, however, would take protocol statements to include at least some assertions about the immediate physical environment. The plausibility of a given candidate for a protocol statement depends on how one analyzes non-inferential justification. Some philosophers rely on the idea of acquaintance. One is non-inferentially justified in believing something when one is directly acquainted with what makes it true. Other philosophers rely on the idea of a state that is in some sense self-presenting. Still others want to understand the notion in terms of the inconceivability of error. The main difficulty in trying to defend a coherent conception of non-inferential justification is to find an account of protocol statements that gives them enough conceptual content to serve as the premises of arguments, while avoiding the charge that the application of concepts always brings with it the possibility of error and the necessity of inference. 

prototype: a theory according to which human cognition involves the deployment of “categories” organized around stereotypical exemplars. Prototype theory differs from traditional theories that take the concepts with which we think to be individuated by means of boundary-specifying necessary and sufficient conditions. Advocates of prototypes hold that our concept of bird, for instance, consists in an indefinitely bounded conceptual “space” in which robins and sparrows are central, and chickens and penguins are peripheral  though the category may be differently organized in different cultures or groups. Rather than being all-ornothing, category membership is a matter of degree. This conception of categories was originally inspired by the notion, developed in a different context by Vitters, of family resemblance. Prototypes were first discussed in detail and given empirical credibility in the work of Eleanor Rosch see, e.g., “On the Internal Structure of Perceptual and Semantic Categories,” 3. 

proudhon: socialist theorist and father of anarchism. He became well known following the publication of What Is Property? 1840, the work containing his main ideas. He argued that the owner of the means of production deprives the workers of a part of their labor: “property is theft.” In order to enable each worker to dispose of his labor, capital and largescale property must be limited. The need to abolish large-scale private property surpassed the immediate need for a state as a controlling agent over chaotic social relationships. To this end he stressed the need for serious reforms in the exchange system. Since the economy and society largely depended on the credit system, Proudhon advocated establishing popular banks that would approve interest-free loans to the poor. Such a mutualism would start the transformation of the actual into a just and nonexploited society of free individuals. Without class antagonism and political authorities, such a society would tend toward an association of communal and industrial collectivities. It would move toward a flexible world federation based on self-management. The main task of social science, then, is to make manifest this immanent logic of social processes. Proudhon’s ideas influenced anarchists, populists Bakunin, Herzen, and syndicalists Jaurès. His conception of self-management was an important inspiration for the later concept of soviets councils. He criticized the inequalities of the contemporary society from the viewpoint of small producers and peasants. Although eclectic and theoretically rather naive, his work attracted the serious attention of his contemporaries and led to a strong attack by Marx in The Holy Family and The Poverty of Philosophy.

prudens: practical reason: In “Epilogue” Grice states that the principle of conversational rationality is a sub-principle of the principle of rationality, simpliciter, which is not involved with ‘communication’ per se. This is an application of Occam’s razor: Rationalities are not to be multiplied beyond necessity.” This motto underlies his aequi-vocality thesis: one reason: desiderative side, judicative side. Literally, ‘practical reason’ is the buletic part of the soul (psyche) that deals with praxis, where the weighing is central. We dont need means-end rationality, we need value-oriented rationality. We dont need the rationality of the means – this is obvious --. We want the rationality of the ends. The end may justify the means. But Grice is looking for what justifies the end. The topic of freedom fascinated Grice, because it merged the practical with the theoretical. Grice sees the conception of freedom as crucial in his elucidation of a rational being. Conditions of freedom are necessary for the very idea, as Kant was well aware. A thief who is forced to steal is just a thief. Grice would engage in a bit of language botany, when exploring the ways the adjective free is used, freely, in ordinary language: free fall, alcohol-free, sugar-free, and his favourite: implicaturum-free. Grices more systematic reflections deal with Pology, or creature construction. A vegetals, for example is less free than an animal, but more free than a stone! And Humans are more free than non-human. Grice wants to deal with some of the paradoxes identified by Kant about freedom, and he succeeds in solving some of them. There is a section on freedom in Action and events for PPQ  where he expands on eleutheria and notes the idiocy of a phrase like free fall. Grice was irritated by the fact that his friend Hart wrote an essay on liberty and not on freedom, cf. praxis. Refs.: essays on ‘practical reason,’ and “Aspects,” in BANC.

ψ-transmissum. Or ‘soul-to-soul transfer’ “Before we study ‘psi’-transmission we should study ‘transmission’ simpliciter. It is cognate with ‘emission.’ So the emissor is a transmissor. And the emissee is a transemissee.  Grice would never have thougth that he had to lecture on what conversation is all about! He would never have lectured on this to his tutees at St. John’s – but at Brighton is all different. So, to communicate, for an emissor is to intend his recipient to be in a state with content “p.” The modality of the ‘state’ – desiderative or creditative – is not important. In a one-off predicament, the emissor draws a skull to indicate that there is danger. So his belief and desire were successfully transmitted. A good way to formulate the point of communication. Note that Grice is never sure about analsans and analysandum: Emissor communicates THAT P iff Emissor M-INTENDS THAT addressee is to psi- that P. Which seems otiose. “It is raining” can be INFORMATIVE, but it is surely INDICATIVE first. So it’s moke like the emissor intends his addressee to believe that he, the utterer believes that p (the belief itself NOT being part of what is meant, of course). So, there is psi-transmission not necessarily when the utterer convinces his addressee, but just when he gets his addressee to BELIEF that he, the utterer, psi-s that p. So the psi HAS BEEN TRANSMITTED. Surely when the Beatles say “HELP” they don’t expect that their addressee will need help. They intend their addressee to HELP them!

pseudo-hallucination, a non-deceptive hallucination. An ordinary hallucination might be thought to comprise two components: i a sensory component, whereby one experiences an image or sensory episode similar in many respects to a veridical perceiving except in being non-veridical; and ii a cognitive component, whereby one takes or is disposed to take the image or sensory episode to be veridical. A pseudohallucination resembles a hallucination, but lacks this second component. In experiencing a pseudohallucination, one appreciates that one is not perceiving veridically. The source of the term seems to be the painter Wassily Kandinsky, who employed it in 5 to characterize a series of apparently drug-induced images experienced and pondered by a friend who recognized them, at the very time they were occurring, not to be veridical. Kandinsky’s account is discussed by Jaspers in his General Psychopathology, 6, and thereby entered the clinical lore. Pseudohallucinations may be brought on by the sorts of pathological condition that give rise to hallucinations, or by simple fatigue, emotional adversity, or loneliness. Thus, a driver, late at night, may react to non-existent objects or figures on the road, and immediately recognize his error. 

psycholinguistics, an interdisciplinary research area that uses theoretical descriptions of language taken from linguistics to investigate psychological processes underlying language production, perception, and learning. There is considerable disagreement as to the appropriate characterization of the field and the major problems. Philosophers discussed many of the problems now studied in psycholinguistics before either psychology or linguistics were spawned, but the self-consciously interdisciplinary field combining psychology and linguistics emerged not long after the birth of the two disciplines. Meringer used the adjective ‘psycholingisch-linguistische’ in an 5 book. Various national traditions of psycholinguistics continued at a steady but fairly low level of activity through the 0s and declined somewhat during the 0s and 0s because of the antimentalist attitudes in both linguistics and psychology. Psycholinguistic researchers in the USSR, mostly inspired by L. S. Vygotsky Thought and Language, 4, were more active during this period in spite of official suppression. Numerous quasi-independent sources contributed to the rebirth of psycholinguistics in the 0s; the most significant was a seminar held at a  during the summer of 3 that led to the publication of Psycholinguistics: A Survey of Theory and Research Problems 4, edited by C. E. Osgood and T. A. Sebeok  a truly interdisciplinary book jointly written by more than a dozen authors. The contributors attempted to analyze and reconcile three disparate approaches: learning theory from psychology, descriptive linguistics, and information theory which came mainly from engineering. The book had a wide impact and led to many further investigations, but the nature of the field changed rapidly soon after its publication with the Chomskyan revolution in linguistics and the cognitive turn in psychology. The two were not unrelated: Chomsky’s positive contribution, Syntactic Structures, was less broadly influential than his negative review Language, 9 of B. F. Skinner’s Verbal Behavior. Against the empiricist-behaviorist view of language understanding and production, in which language is merely the exhibition of a more complex form of behavior, Chomsky argued the avowedly rationalist position that the ability to learn and use language is innate and unique to humans. He emphasized the creative aspect of language, that almost all sentences one hears or produces are novel. One of his premises was the alleged infinity of sentences in natural languages, but a less controversial argument can be given: there are tens of millions of five-word sentences in English, all of which are readily understood by speakers who have never heard them. Chomsky’s work promised the possibility of uncovering a very special characteristic of the human mind. But the promise was qualified by the disclaimer that linguistic theory describes only the competence of the ideal speaker. Many psycholinguists spent countless hours during the 0s and 0s seeking the traces of underlying competence beneath the untidy performances of actual speakers. During the 0s, as Chomsky frequently revised his theories of syntax and semantics in significant ways, and numerous alternative linguistic models were under consideration, psychologists generated a range of productive research problems that are increasingly remote from the Chomskyan beginnings. Contemporary psycholinguistics addresses phonetic, phonological, syntactic, semantic, and pragmatic influences on language processing. Few clear conclusions of philosophical import have been established. For example, several decades of animal research have shown that other species can use significant portions of human language, but controversy abounds over how central those portions are to language. Studies now clearly indicate the importance of word frequency and coarticulation, the dependency of a hearer’s identification of a sound as a particular phoneme, or of a visual pattern as a particular letter, not only on the physical features of the pattern but on the properties of other patterns not necessarily adjacent. Physically identical patterns may be heard as a d in one context and a t in another. It is also accepted that at least some of the human lignuistic abilities, particularly those involved in reading and speech perception, are relatively isolated from other cognitive processes. Infant studies show that children as young as eight months learn statistically important patterns characteristic of their natural language  suggesting a complex set of mechanisms that are automatic and invisible to us.

Pufendorf, S., G. historian and theorist of natural law. Pufendorf was influenced by both Grotius and Hobbes. He portrayed people as contentious and quarrelsome, yet as needing one another’s company and assistance. Natural law shows how people can live with one another while pursuing their own conflicting projects. To minimize religious disputes about morals, Pufendorf sought a way of deriving laws of nature from observable facts alone. Yet he thought divine activity essential to morality. He opened his massive Latin treatise On the Law of Nature and of Nations 1672 with a voluntarist account of God’s creation of the essence of mankind: given that we have the nature God gave us, certain laws must be valid for us, but only God’s will determined our nature. As a result, our nature indicates God’s will for us. Hence observable facts about ourselves show us what laws God commands us to obey. Because we so obviously need one another’s assistance, the first law is to increase our sociability, i.e. our willingness to live together. All other laws indicate acts that would bring about this end. In the course of expounding the laws he thought important for the development of social life to the high cultural level our complex nature points us toward, Pufendorf analyzed all the main points that a full legal system must cover. He presented the rudiments of laws of marriage, property, inheritance, contract, and international relations in both war and peace. He also developed the Grotian theory of personal rights, asserting for the first time that rights are pointless unless for each right there are correlative duties binding on others. Taking obligation as his fundamental concept, he developed an important distinction between perfect and imperfect duties and rights. And in working out a theory of property he suggested the first outlines of a historical sociology of wealth later developed by Adam Smith. Pufendorf’s works on natural law were textbooks for all of Europe for over a century and were far more widely read than any other treatments of the subject. 

pulchrum -- beauty, an aesthetic property commonly thought of as a species of aesthetic value. As such, it has been variously thought to be 1 a simple, indefinable property that cannot be defined in terms of any other properties; 2 a property or set of properties of an object that makes the object capable of producing a certain sort of pleasurable experience in any suitable perceiver; or 3 whatever produces a particular sort of pleasurable experience, even though what produces the experience may vary from individual to individual. It is in this last sense that beauty is thought to be “in the eye of the beholder.” If beauty is a simple, indefinable property, as in 1, then it cannot be defined conceptually and has to be apprehended by intuition or taste. Beauty, on this account, would be a particular sort of aesthetic property. If beauty is an object’s Bayle, Pierre beauty 75   75 capacity to produce a special sort of pleasurable experience, as in 2, then it is necessary to say what properties provide it with this capacity. The most favored candidates for these have been formal or structural properties, such as order, symmetry, and proportion. In the Philebus Plato argues that the form or essence of beauty is knowable, exact, rational, and measurable. He also holds that simple geometrical shapes, simple colors, and musical notes all have “intrinsic beauty,” which arouses a pure, “unmixed” pleasure in the perceiver and is unaffected by context. In the sixteenth and seventeenth centuries many treatises were written on individual art forms, each allegedly governed by its own rules. In the eighteenth century, Hutcheson held that ‘beauty’ refers to an “idea raised in us,” and that any object that excites this idea is beautiful. He thought that the property of the object that excites this idea is “uniformity in variety.” Kant explained the nature of beauty by analyzing judgments that something is beautiful. Such judgments refer to an experience of the perceiver. But they are not merely expressions of personal experience; we claim that others should also have the same experience, and that they should make the same judgment i.e., judgments that something is beautiful have “universal validity”. Such judgments are disinterested  determined not by any needs or wants on the part of the perceiver, but just by contemplating the mere appearance of the object. These are judgments about an object’s free beauty, and making them requires using only those mental capacities that all humans have by virtue of their ability to communicate with one another. Hence the pleasures experienced in response to such beauty can in principle be shared by anyone. Some have held, as in 3, that we apply the term ‘beautiful’ to things because of the pleasure they give us, and not on the basis of any specific qualities an object has. Archibald Alison held that it is impossible to find any properties common to all those things we call beautiful. Santayana believed beauty is “pleasure regarded as a quality of a thing,” and made no pretense that certain qualities ought to produce that pleasure. The Grecian term to kalon, which is often tr. as ‘beauty’, did not refer to a thing’s autonomous aesthetic value, but rather to its “excellence,” which is connected with its moral worth and/or usefulness. This concept is closer to Kant’s notion of dependent beauty, possessed by an object judged as a particular kind of thing such as a beautiful cat or a beautiful horse, than it is to free beauty, possessed by an object judged simply on the basis of its appearance and not in terms of any concept of use

punishment, a distinctive form of legal sanction, distinguished first by its painful or unpleasant nature to the offender, and second by the ground on which the sanction is imposed, which must be because the offender offended against the norms of a society. None of these three attributes is a strictly necessary condition for proper use of the word ‘punishment’. There may be unpleasant consequences visited by nature upon an offender such that he might be said to have been “punished enough”; the consequences in a given case may not be unpleasant to a particular offender, as in the punishment of a masochist with his favorite form of self-abuse; and punishment may be imposed for reasons other than offense against society’s norms, as is the case with punishment inflicted in order to deter others from like acts. The “definitional stop” argument in discussions of punishment seeks to tie punishment analytically to retributivism. Retributivism is the theory that punishment is justified by the moral desert of the offender; on this view, a person who culpably does a wrongful action deserves punishment, and this desert is a sufficient as well as a necessary condition of just punishment. Punishment of the deserving, on this view, is an intrinsic good that does not need to be justified by any other good consequences such punishment may achieve, such as the prevention of crime. Retributivism is not to be confused with the view that punishment satisfies the feelings of vengeful citizens nor with the view that punishment preempts such citizens from taking the law into their own hands by vigilante action  these latter views being utilitarian. Retributivism is also not the view sometimes called “weak” or “negative” retributivism that only the deserving are to be punished, for desert on such a view typically operates only as a limiting and not as a justifying condition of punishment. The thesis known as the “definitional stop” says that punishment must be retributive in its justification if it is to be punishment at all. Bad treatment inflicted in order to prevent future crime is not punishment but deserves another name, usually ‘telishment’. The dominant justification of non-retributive punishment or telishment is deterrence. The good in whose name the bad of punishing is justified, on this view, is prevention of future criminal acts. If punishment is inflicted to prevent the offender from committing future criminal acts, it is styled “specific” or “special” deterrence; if punishment is inflicted to prevent others from committing future criminal acts, it is styled “general” deterrence. In either case, punishment of an action is justified by the future effect of that punishment in deterring future actors from committing crimes. There is some vagueness in the notion of deterrence because of the different mechanisms by which potential criminals are influenced not to be criminals by the example of punishment: such punishment may achieve its effects through fear or by more benignly educating those would-be criminals out of their criminal desires.

Pyrrho of Elis, Grecian philosopher, regarded as the founder of Skepticism. Like Socrates, he wrote nothing, but impressed many with provocative ideas and calm demeanor. His equanimity was admired by Epicurus; his attitude of indifference influenced early Stoicism; his attack on knowledge was taken over by the skeptical Academy; and two centuries later, a revival of Skepticism adopted his name. Many of his ideas were anticipated by earlier thinkers, notably Democritus. But in denying the veracity of all sensations and beliefs, Pyrrho carried doubt to new and radical extremes. According to ancient anecdote, which presents him as highly eccentric, he paid so little heed to normal sensibilities that friends often had to rescue him from grave danger; some nonetheless insisted he lived into his nineties. He is also said to have emulated the “naked teachers” as the Hindu Brahmans were called by Grecians whom he met while traveling in the entourage of Alexander the Great. Pyrrho’s chief exponent and publicist was Timon of Phlius c.325c.235 B.C.. His bestpreserved work, the Silloi “Lampoons”, is a parody in Homeric epic verse that mocks the pretensions of numerous philosophers on an imaginary visit to the underworld. According to Timon, Pyrrho was a “negative dogmatist” who affirmed that knowledge is impossible, not because our cognitive apparatus is flawed, but because the world is fundamentally indeterminate: things themselves are “no more” cold than hot, or good than bad. But Timon makes clear that the key to Pyrrho’s Skepticism, and a major source of his impact, was the ethical goal he sought to achieve: by training himself to disregard all perception and values, he hoped to attain mental tranquility. 

Pythagoras, the most famous of the pre-Socratic Grecian philosophers. He emigrated from the island of Samos off Asia Minor to Croton southern Italy in 530. There he founded societies based on a strict way of life. They had great political impact in southern Italy and aroused opposition that resulted in the burning of their meeting houses and, ultimately, in the societies’ disappearance in the fourth century B.C. Pythagoras’s fame grew exponentially with the pasage of time. Plato’s immediate successors in the Academy saw true philosophy as an unfolding of the original insight of Pythagoras. By the time of Iamblichus late third century A.D., Pythagoreanism and Platonism had become virtually identified. Spurious writings ascribed both to Pythagoras and to other Pythagoreans arose beginning in the third century B.C. Eventually any thinker who saw the natural world as ordered according to pleasing mathematical relations e.g., Kepler came to be called a Pythagorean. Modern scholarship has shown that Pythagoras was not a scientist, mathematician, or systematic philosopher. He apparently wrote nothing. The early evidence shows that he was famous for introducing the doctrine of metempsychosis, according to which the soul is immortal and is reborn in both human and animal incarnations. Rules were established to purify the soul including the prohibition against eating beans and the emphasis on training of the memory. General reflections on the natural world such as “number is the wisest thing” and “the most beautiful, harmony” were preserved orally. A belief in the mystical power of number is also visible in the veneration for the tetractys tetrad: the numbers 14, which add up to the sacred number 10. The doctrine of the harmony of the spheres  that the heavens move in accord with number and produce music  may go back to Pythagoras. It is often assumed that there must be more to Pythagoras’s thought than this, given his fame in the later tradition. However, Plato refers to him only as the founder of a way of life Republic 600a9. In his account of pre-Socratic philosophy, Aristotle refers not to Pythagoras himself, but to the “so-called Pythagoreans” whom he dates in the fifth century. 


Q

quale: a property of a mental state or event, in particular of a sensation and a perceptual state, which determine “what it is like” to have them. Sometimes ‘phenomenal properties’ and ‘qualitative features’ are used with the same meaning. The felt difference between pains and itches is said to reside in differences in their “qualitative character,” i.e., their qualia. For those who accept an “actobject” conception of perceptual experience, qualia may include such properties as “phenomenal redness” and “phenomenal roundness,” thought of as properties of sense-data, “phenomenal objects,” or portions of the visual field. But those who reject this conception do not thereby reject qualia; a proponent of the adverbial analysis of perceptual experience can hold that an experience of “sensing redly” is so in virtue of, in part, what qualia it has, while denying that there is any sense in which the experience itself is red. Qualia are thought of as non-intentional, i.e., non-representational, features of the states that have them. So in a case of “spectrum inversion,” where one person’s experiences of green are “qualitatively” just like another person’s experiences of red, and vice versa, the visual experiences the two have when viewing a ripe tomato would be alike in their intentional features both would be of a red, round, bulgy surface, but would have different qualia. Critics of physicalist and functionalist accounts of mind have argued from the possibility of spectrum inversion and other kinds of “qualia inversion,” and from such facts as that no physical or functional description will tell one “what it is like” to smell coffee, that such accounts cannot accommodate qualia. Defenders of such accounts are divided between those who claim that their accounts can accommodate qualia and those who claim that qualia are a philosophical myth and thus that there are none to accommodate.  qualitative predicate, a kind of predicate postulated in some attempts to solve the grue paradox. 1 On the syntactic view, a qualitative predicate is a syntactically more or less simple predicate. Such simplicity, however, is relative to the choice of primitives in a language. In English, ‘green’ and ‘blue’ are primitive, while ‘grue’ and ‘bleen’ must be introduced by definitions ‘green and first examined before T, or blue otherwise’, ‘blue and first examined before T, or green otherwise’, respectively. In other languages, ‘grue’ and ‘bleen’ may be primitive and hence “simple,” while ‘green’ and ‘blue’ must be introduced by definitions ‘grue and first examined before T, or bleen otherwise’, ‘bleen and first examined before T, or grue otherwise’, respectively. 2 On the semantic view, a qualitative predicate is a predicate to which there corresponds a property that is “natural” to us or of easy semantic access. The quality of greenness is easy and natural; the quality of grueness is strained. 3 On the ontological view, a qualitative predicate is a predicate to which there corresponds a property that is woven into the causal or modal structure of reality in a way that gruesome properties are not.  qualities, properties or characteristics. There are three specific philosophical senses. 1 Qualities are physical properties, logical constructions of physical properties, or dispositions. Physical properties, such as mass, shape, and electrical charge, are properties in virtue of which objects can enter into causal relations. Logical constructions of physical properties include conjunctions and disjunctions of them; being 10 # .02 cm long is a disjunctive property. A disposition of an object is a potential for the object to enter into a causal interaction of some specific kind under some specific condition; e.g., an object is soluble in water if and only if it would dissolve were it in enough pure water. Locke held a very complex theory of powers. On Locke’s theory, the dispositions of objects are a kind of power and the human will is a kind of power. However, the human will is not part of the modern notion of disposition. So, predicating a disposition of an object implies a subjunctive conditional of the form: if such-and-such were to happen to the object, then so-and-so would happen to it; that my vase is fragile implies that if my vase were to be hit sufficiently hard then it would break. Whether physical properties are distinct from dispositions is disputed. Three sorts of qualities are often distinguished. Primary qualities are physical properties or logical constructions from physical properties. Secondary qualities are dispositions to produce sensory experiences of certain phenomenal sorts under appropriate conditions. The predication of a secondary quality, Q, to an object implies that if the object were to be perceived under normal conditions then the object would appear to be Q to the perceivers: if redness is a secondary quality, then that your coat is red implies that if your coat were to be seen under normal conditions, it would look red. Locke held that the following are secondary qualities: colors, tastes, smells, sounds, and warmth or cold. Tertiary qualities are dispositions that are not secondary qualities, e.g. fragility. Contrary to Locke, the color realist holds that colors are either primary or tertiary qualities; so that x is yellow is logically independent of the fact that x looks yellow under normal conditions. Since different spectral reflectances appear to be the same shade of yellow, some color realists hold that any shade of yellow is a disjunctive property whose components are spectral reflectances. 2 Assuming a representative theory of perception, as Locke did, qualities have two characteristics: qualities are powers or dispositions of objects to produce sensory experiences sensedata on some theories in humans; and, in sensory experience, qualities are represented as intrinsic properties of objects. Instrinsic properties of objects are properties that objects have independently of their environment. Hence an exact duplicate of an object has all the intrinsic properties of the original, and an intrinsic property of x never has the form, x-stands-in-suchand-such-a-relation-to-y. Locke held that the primary qualities are extension size, figure shape, motion or rest, solidity impenetrability, and number; the primary qualities are correctly represented in perception as intrinsic features of objects, and the secondary qualities listed in 1 are incorrectly represented in perception as intrinsic features of objects. Locke seems to have been mistaken in holding that number is a quality of objects. Positional qualities are qualities defined in terms of the relative positions of points in objects and their surrounding: shape, size, and motion and rest. Since most of Locke’s primary qualities are positional, some non-positional quality is needed to occupy positions. On Locke’s account, solidity fulfills this role, although some have argued Hume that solidity is not a primary quality. 3 Primary qualities are properties common to and inseparable from all matter; secondary qualities are not really qualities in objects, but only powers of objects to produce sensory effects in us by means of their primary qualities. This is another use of ‘quality’ by Locke, where ‘primary’ functions much like ‘real’ and real properties are given by the metaphysical assumptions of the science of Locke’s time. Qualities are distinct from representations of them in predications. Sometimes the same quality is represented in different ways by different predications: ‘That is water’ and ‘That is H2O’. The distinction between qualities and the way they are represented in predications opens up the Lockean possibility that some qualities are incorrectly represented in some predications. Features of predications are sometimes used to define a quality; dispositions are sometimes defined in terms of subjunctive conditionals see definition of ‘secondary qualities’ in 1, and disjunctive properties are defined in terms of disjunctive predications. Features of predications are also used in the following definition of ‘independent qualities’: two qualities, P and Q, are independent if and only if, for any object x, the predication of P and of Q to x are logically independent i.e., that x is P and that x is Q are logically independent; circularity and redness are independent, circularity and triangularity are dependent. If two determinate qualities, e.g., circularity and triangularity, belong to the same determinable, say shape, then they are dependent, but if two determinate qualities, e.g., squareness and redness, belong to different determinables, say shape and color, they are independent.

quantum:  Quantification: H. P. Grice, “Every nice girl loves a sailor.” -- the application of one or more quantifiers e.g., ‘for all x’, ‘for some y’ to an open formula. A quantification or quantified sentence results from first forming an open formula from a sentence by replacing expressions belonging to a certain class of expressions in the sentences by variables whose substituends are the expressions of that class and then prefixing the formula with quantifiers using those variables. For example, from ‘Bill hates Mary’ we form ‘x hates y’, to which we prefix the quantifiers ‘for all x’ and ‘for some y’, getting the quantification sentence ‘for all x, for some y, x hates y’ ‘Everyone hates someone’. In referential quantification only terms of reference may be replaced by variables. The replaceable terms of reference are the substituends of the variables. The values of the variables are all those objects to which reference could be made by a term of reference of the type that the variables may replace. Thus the previous example ‘for all x, for some y, x hates y’ is a referential quantification. Terms standing for people ‘Bill’, ‘Mary’, e.g. are the substituends of the variables ‘x’ and ‘y’. And people are the values of the variables. In substitutional quantification any type of term may be replaced by variables. A variable replacing a term has as its substituends all terms of the type of the replaced term. For example, from ‘Bill married Mary’ we may form ‘Bill R Mary’, to which we prefix the quantifier ‘for some R’, getting the substitutional quantification ‘for some R, Bill R Mary’. This is not a referential quantification, since the substituends of ‘R’ are binary predicates such as ‘marries’, which are not terms of reference. Referential quantification is a species of objectual quantification. The truth conditions of quantification sentences objectually construed are understood in terms of the values of the variable bound by the quantifier. Thus, ‘for all v, fv’ is true provided ‘fv’ is true for all values of the variable ‘v’; ‘for some v, fv’ is true provided ‘fv’ is true for some value of the variable ‘v’. The truth or falsity of a substitutional quantification turns instead on the truth or falsity of the sentences that result from the quantified formula by replacing variables by their substituends. For example, ‘for some R, Bill R Mary’ is true provided some sentence of the form ‘Bill R Mary’ is true. In classical logic the universal quantifier ‘for all’ is definable in terms of negation and the existential quantifier ‘for some’: ‘for all x’ is short for ‘not for some x not’. The existential quantifier is similarly definable in terms of negation and the universal quantifier. In intuitionistic logic, this does not hold. Both quantifiers are regarded as primitive. Then there’s quantifying in, use of a quantifier outside of an opaque construction to attempt to bind a variable within it, a procedure whose legitimacy was first questioned by Quine. An opaque construction is one that resists substitutivity of identity. Among others, the constructions of quotation, the verbs of propositional attitude, and the logical modalities can give rise to opacity. For example, the position of ‘six’ in: 1 ‘six’ contains exactly three letters is opaque, since the substitution for ‘six’ by its codesignate ‘immediate successor of five’ renders a truth into a falsehood: 1H ‘the immediate successor of five’ contains exactly three letters. Similarly, the position of ‘the earth’ in: 2 Tom believes that the earth is habitable is opaque, if the substitution of ‘the earth’ by its codesignate ‘the third planet from the sun’ renders a sentence that Tom would affirm into one that he would deny: 2H Tom believes that the third planet from the sun is habitable. Finally, the position of ‘9’ and of ‘7’ in: 3 Necessarily 9  7 is opaque, since the substitution of ‘the number of major planets’ for its codesignate ‘9’ renders a truth into a falsehood: 3H Necessarily the number of major planets  7. Quine argues that since the positions within opaque constructions resist substitutivity of identity, they cannot meaningfully be quantified. Accordingly, the following three quantified sentences are meaningless: 1I Ex ‘x’  7, 2I Ex Tom believes that x is habitable, 3I Ex necessarily x  7. 1I, 2I, and 3I are meaningless, since the second occurrence of ‘x’ in each of them does not function as a variable in the ordinary nonessentialist quantificational way. The second occurrence of ‘x’ in 1I functions as a name that names the twenty-fourth letter of the alphabet. The second occurrences of ‘x’ in 2I and in 3I do not function as variables, since they do not allow all codesignative terms as substituends without change of truth-value. Thus, they may take objects as values but only objects designated in certain ways, e.g., in terms of their intensional or essential properties. So, short of acquiescing in an intensionalist or essentialist metaphysics, Quine argues, we cannot in general quantify into opaque contexts.  Quantum: one of Aristotle’s categories. Cicero’s translation of Aristotle -- quantum logic, the logic of which the models are certain non-Boolean algebras derived from the mathematical representation of quantum mechanical systems. The models of classical logic are, formally, Boolean algebras. This is the central notion of quantum logic in the literature, although the term covers a variety of modal logics, dialogics, and operational logics proposed to elucidate the structure of quantum mechanics and its relation to classical mechanics. The dynamical quantities of a classical mechanical system position, momentum, energy, etc. form a commutative algebra, and the dynamical properties of the system e.g., the property that the position lies in a specified range, or the property that the momentum is greater than zero, etc. form a Boolean algebra. The transition from classical to quantum mechanics involves the transition from a commutative algebra of dynamical quantities to a noncommutative algebra of so-called observables. One way of understanding the conceptual revolution from classical to quantum mechanics is in terms of a shift from the class of Boolean algebras to a class of non-Boolean algebras as the appropriate relational structures for the dynamical properties of mechanical systems, hence from a Boolean classical logic to a non-Boolean quantum logic as the logic applicable to the fundamental physical processes of our universe. This conception of quantum logic was developed formally in a classic 6 paper by G. Birkhoff and J. von Neumann although von Neumann first proposed the idea in 7. The features that distinguish quantum logic from classical logic vary with the formulation. In the Birkhoffvon Neumann logic, the distributive law of classical logic fails, but this is by no means a feature of all versions of quantum logic. It follows from Gleason’s theorem 7 that the non-Boolean models do not admit two-valued homomorphisms in the general case, i.e., there is no partition of the dynamical properties of a quantum mechanical system into those possessed by the system and those not possessed by the system that preserves algebraic structure, and equivalently no assignment of values to the observables of the system that preserves algebraic structure. This result was proved independently for finite sets of observables by S. Kochen and E. P. Specker 7. It follows that the probabilities specified by the Born interpretation of the state function of a quantum mechanical system for the results of measurements of observables cannot be derived from a probability distribution over the different possible sets of dynamical properties of the system, or the different possible sets of values assignable to the observables of which one set is presumed to be actual, determined by hidden variables in addition to the state function, if these sets of properties or values are required to preserve algebraic structure. While Bell’s theorem 4 excludes hidden variables satisfying a certain locality condition, the Kochen-Specker theorem relates the non-Booleanity of quantum logic to the impossibility of hidden variable extensions of quantum mechanics, in which value assignments to the observables satisfy constraints imposed by the algebraic structure of the observables. Then there’s quantum mechanics, also called quantum theory, the science governing objects of atomic and subatomic dimensions. Developed independently by Werner Heisenberg as matrix mechanics, 5 and Erwin Schrödinger as wave mechanics, 6, quantum mechanics breaks with classical treatments of the motions and interactions of bodies by introducing probability and acts of measurement in seemingly irreducible ways. In the widely used Schrödinger version, quantum mechanics associates with each physical system a time-dependent function, called the state function alternatively, the state vector or Y function. The evolution of the system is represented by the temporal transformation of the state function in accord with a master equation, known as the Schrödinger equation. Also associated with a system are “observables”: in principle measurable quantities, such as position, momentum, and energy, including some with no good classical analogue, such as spin. According to the Born interpretation 6, the state function is understood instrumentally: it enables one to calculate, for any possible value of an observable, the probability that a measurement of that observable would find that particular value. The formal properties of observables and state functions imply that certain pairs of observables such as linear momentum in a given direction, and position in the same direction are incompatible in the sense that no state function assigns probability 1 to the simultaneous determination of exact values for both observables. This is a qualitative statement of the Heisenberg uncertainty principle alternatively, the indeterminacy principle, or just the uncertainty principle. Quantitatively, that principle places a precise limit on the accuracy with which one may simultaneously measure a pair of incompatible observables. There is no corresponding limit, however, on the accuracy with which a single observable say, position alone, or momentum alone may be measured. The uncertainty principle is sometimes understood in terms of complementarity, a general perspective proposed by Niels Bohr according to which the connection between quantum phenomena and observation forces our classical concepts to split into mutually exclusive packages, both of which are required for a complete understanding but only one of which is applicable under any particular experimental conditions. Some take this to imply an ontology in which quantum objects do not actually possess simultaneous values for incompatible observables; e.g., do not have simultaneous position and momentum. Others would hold, e.g., that measuring the position of an object causes an uncontrollable change in its momentum, in accord with the limits on simultaneous accuracy built into the uncertainty principle. These ways of treating the principle are not uncontroversial. Philosophical interest arises in part from where the quantum theory breaks with classical physics: namely, from the apparent breakdown of determinism or causality that seems to result from the irreducibly statistical nature of the theory, and from the apparent breakdown of observer-independence or realism that seems to result from the fundamental role of measurement in the theory. Both features relate to the interpretation of the state function as providing only a summary of the probabilities for various measurement outcomes. Einstein, in particular, criticized the theory on these grounds, and in 5 suggested a striking thought experiment to show that, assuming no action-at-a-distance, one would have to consider the state function as an incomplete description of the real physical state for an individual system, and therefore quantum mechanics as merely a provisional theory. Einstein’s example involved a pair of systems that interact briefly and then separate, but in such a way that the outcomes of various measurements performed on each system, separately, show an uncanny correlation. In 1 the physicist David Bohm simplified Einstein’s example, and later 7 indicated that it may be realizable experimentally. The physicist John S. Bell then formulated a locality assumption 4, similar to Einstein’s, that constrains factors which might be used in describing the state of an individual system, so-called hidden variables. Locality requires that in the EinsteinBohm experiment hidden variables not allow the measurement performed on one system in a correlated pair immediately to influence the outcome obtained in measuring the other, spatially separated system. Bell demonstrated that locality in conjunction with other assumptions about hidden variables restricts the probabilities for measurement outcomes according to a system of inequalities known as the Bell inequalities, and that the probabilities of certain quantum systems violate these inequalities. This is Bell’s theorem. Subsequently several experiments of the Einstein-Bohm type have been performed to test the Bell inequalities. Although the results have not been univocal, the consensus is that the experimental data support the quantum theory and violate the inequalities. Current research is trying to evaluate the implications of these results, including the extent to which they rule out local hidden variables. See J. Cushing and E. McMullin, eds., Philosophical Consequences of Quantum Theory, 9. The descriptive incompleteness with which Einstein charged the theory suggests other problems. A particularly dramatic one arose in correspondence between Schrödinger and Einstein; namely, the “gruesome” Schrödinger cat paradox. Here a cat is confined in a closed chamber containing a radioactive atom with a fifty-fifty chance of decaying in the next hour. If the atom decays it triggers a relay that causes a hammer to fall and smash a glass vial holding a quantity of    766 prussic acid sufficient to kill the cat. According to the Schrödinger equation, after an hour the state function for the entire atom ! relay ! hammer ! glass vial ! cat system is such that if we observe the cat the probability for finding it alive dead is 50 percent. However, this evolved state function is one for which there is no definite result; according to it, the cat is neither alive nor dead. How then does any definite fact of the matter arise, and when? Is the act of observation itself instrumental in bringing about the observed result, does that result come about by virtue of some special random process, or is there some other account compatible with definite results of measurements? This is the so-called quantum measurement problem and it too is an active area of research. 

quasi-demonstratum: The use of ‘quasi-‘ is implicatural. Grice is implicating this is NOT a demonstratum. By a demonstratum he is having in mind a Kaplanian ‘dthis’ or ‘dthat.’ Grice was obsessed with this or that. An abstractum (such as “philosopher”) needs to be attached in a communicatum by what Grice calls a ‘quasi-demonstrative,’ and for which he uses “φ.” Consider, Grice says, an utterance, out of the blue, such as ‘The philosopher in the garden seems bored,’ involving two iota-operators. As there may be more that a philosopher in a garden in the great big world, the utterer intends his addressee to treat the utterance as expandable into ‘The A which is φ is B,’ where “φ” is a quasi-demonstrative epithet to be identified in a particular context of utterance. The utterer intends that, to identify  the denotatum of “φ” for a particular utterance of ‘The philosopher in the garden seems bored,’ the addressee wil proceed via the identification of a particular philosopher, say Grice, as being a good candidate for being the philosopher meant. The addressee is also intended to identify the candidate for a denotatum of φ by finding in the candidate a feature, e. g., that of being the garden at St. John’s, which is intended to be used to yield a composite epithet (‘philosopher in St. John’s garden’), which in turn fills the bill of being the epithet which the utterer believes is being uniquely satisfied by the philosopher selected as the candidate. Determining the denotatum of “φ” standardly involve determining what feature the utterer believes is uniquely instantiated by the predicate “philosopher.” This in turn involves satisfying oneself that some particular feature is in fact uniquely satisfied by a particular actual item, viz. a particular philosopher such as Grice seeming bored in the garden of St. John’s.


A.M. Quinton’s Gedanke Experiment: from “Spaces and Times,” Philosophy.“hardly Thought Out” – Is this apriori or a posteriori? H. P. Grice. Space is ordinarily seen to be a unique individual. All real things are contained in one and the same space, and all spaces are part of the one space. In principle, every place can be reached from every other place by traveling through intermediate places. The spatial relation is symmetrical. Grice’s friend, A. M. Quinton devised a thought experiment to challenge this picture. Suppose that we have richly coherent and connected experience in our dreams just as we have in waking life, so that it becomes arbitrary to claim that our dream experience is not of an objectively existing world like the world of our waking experience. If the space of my waking world and my dream world are not mutually accessible, it is unlikely that we are justified in claiming to be living in a single spatially isolated world. Hence, space is not essentially singular. In assessing this account, we might distinguish between systematic and public physical space and fragmentary and private experiential space. The two-space myth raises questions about how we can justify moving from experiential space to objective space in the world as it is. “We can at least conceive circumstances in which we should have good reason to say that we know of real things located in two distinct spaces.” Quinton, “Spaces and Times,” Philosophy 37.

quod: quid – quiddity. A term used by Grice when talking to his wife. “What quiddity did you buy?”

qv-quæstio -- x-question: Grice borrowed the erotetic from Cook Wilson, who in fact was influenced by Stout and will also influence Collingwood. While Grice starts by considering the pseudo-distinction between x-questions and yes/no questions, he soon finds out that they all reduce to the x-question, since a yes/no question obviously asks for a variable (the truth value of the whole proposition) to be filled. Grice sometimes follows Ryle who had quoted Carnap on the ‘w  frage.’ Grice is aware of the ‘wh’ rune in Anglo-Saxon, but was confused by ‘how.’ “For fun, I will spell ‘how,’ ‘whow.’” Although a Midlander Grice preferred the northern English pronunciation of aspirating the ‘wh-‘ and was irritated that only ‘who’ and ‘whose’ keep the aspiration. Note that “Where is your wife?” is a qu-quaestio, but “(a) in the kitchen, (b) in the bedroom” provides a ‘p v q’ as an answer – “Disjunctive answers to intrusive questions.” Cf. “Iffy answers to intrusive questions.” “The lady doth protest too much: ampliative conjunctive answers to intrusive questions.”

Radix -- Radix -- Grice often talked about logical atomism and molecular propositions – and radix – which is an atomic metaphor -- Democritus, Grecian preSocratic philosopher. He was born at Abdera, in Thrace. Building on Leucippus and his atomism, he developed the atomic theory in The Little World-system and numerous other writings. In response to the Eleatics’ argument that the impossibility of not-being entailed that there is no change, the atomists posited the existence of a plurality of tiny indivisible beings  the atoms  and not-being  the void, or empty space. Atoms do not come into being or perish, but they do move in the void, making possible the existence of a world, and indeed of many worlds. For the void is infinite in extent, and filled with an infinite number of atoms that move and collide with one another. Under the right conditions a concentration of atoms can begin a vortex motion that draws in other atoms and forms a spherical heaven enclosing a world. In our world there is a flat earth surrounded by heavenly bodies carried by a vortex motion. Other worlds like ours are born, flourish, and die, but their astronomical configurations may be different from ours and they need not have living creatures in them. The atoms are solid bodies with countless shapes and sizes, apparently having weight or mass, and capable of motion. All other properties are in some way derivative of these basic properties. The cosmic vortex motion causes a sifting that tends to separate similar atoms as the sea arranges pebbles on the shore. For instance heavier atoms sink to the center of the vortex, and lighter atoms such as those of fire rise upward. Compound bodies can grow by the aggregations of atoms that become entangled with one another. Living things, including humans, originally emerged out of slime. Life is caused by fine, spherical soul atoms, and living things die when these atoms are lost. Human culture gradually evolved through chance discoveries and imitations of nature. Because the atoms are invisible and the only real properties are properties of atoms, we cannot have direct knowledge of anything. Tastes, temperatures, and colors we know only “by convention.” In general the senses cannot give us anything but “bastard” knowledge; but there is a “legitimate” knowledge based on reason, which takes over where the senses leave off  presumably demonstrating that there are atoms that the senses cannot testify of. Democritus offers a causal theory of perception  sometimes called the theory of effluxes  accounting for tastes in terms of certain shapes of atoms and for sight in terms of “effluences” or moving films of atoms that impinge on the eye. Drawing on both atomic theory and conventional wisdom, Democritus develops an ethics of moderation. The aim of life is equanimity euthumiê, a state of balance achieved by moderation and proportionate pleasures. Envy and ambition are incompatible with the good life. Although Democritus was one of the most prolific writers of antiquity, his works were all lost. Yet we can still identify his atomic theory as the most fully worked out of pre-Socratic philosophies. His theory of matter influenced Plato’s Timaeus, and his naturalist anthropology became the prototype for liberal social theories. Democritus had no immediate successors, but a century later Epicurus transformed his ethics into a philosophy of consolation founded on atomism. Epicureanism thus became the vehicle through which atomic theory was transmitted to the early modern period. 

ramseyified description. Grice enjoyed Ramsey’s Engish humour: if you can say it, you can’t whistle it either. Applied by Grice in “Method.”Agent A is in a D state just in case there is a predicate “D”  introduced via implicit definition by nomological generalisation L within theory θ, such L obtains, A instantiates D. Grice distinguishes the ‘descriptor’ from a more primitive ‘name.’ The reference is to Ramsey. The issue is technical and relates to the introduction of a predicate constant – something he would never have dared to at Oxford with Gilbert Ryle and D. F. Pears next to him! But in the New World, they loved a formalism! And of course Ramsey would not have anything to do with it! Ramsey: p. r. – cited by Grice, “The Ramseyfied description. Frank Plumpton 330, influential 769 R    769 British philosopher of logic and mathematics. His primary interests were in logic and philosophy, but decades after his untimely death two of his publications sparked new branches of economics, and in pure mathematics his combinatorial theorems gave rise to “Ramsey theory” Economic Journal 7, 8; Proc. London Math. Soc., 8. During his lifetime Ramsey’s philosophical reputation outside Cambridge was based largely on his architectural reparation of Whitehead and Russell’s Principia Mathematica, strengthening its claim to reduce mathematics to the new logic formulated in Volume 1  a reduction rounded out by Vitters’s assessment of logical truths as tautologous. Ramsey clarified this logicist picture of mathematics by radically simplifying Russell’s ramified theory of types, eliminating the need for the unarguable axiom of reducibility Proc. London Math. Soc., 5. His philosophical work was published mostly after his death. The canon, established by Richard Braithwaite The Foundations of Mathematics . . . , 1, remains generally intact in D. H. Mellor’s edition Philosophical Papers, 0. Further writings of varying importance appear in his Notes on Philosophy, Probability and Mathematics M. C. Galavotti, ed., 1 and On Truth Nicholas Rescher and Ulrich Majer, eds., 1. As an undergraduate Ramsey observed that the redundancy account of truth “enables us to rule out at once some theories of truth such as that ‘to be true’ means ‘to work’ or ‘to cohere’ since clearly ‘p works’ and ‘p coheres’ are not equivalent to ‘p’.” Later, in the canonical “Truth and Probability” 6, he readdressed to knowledge and belief the main questions ordinarily associated with truth, analyzing probability as a mode of judgment in the framework of a theory of choice under uncertainty. Reinvented and acknowledged by L. J. Savage Foundations of Statistics, 4, this forms the theoretical basis of the currently dominant “Bayesian” view of rational decision making. Ramsey cut his philosophical teeth on Vitters’s Tractatus LogicoPhilosophicus. His translation appeared in 2; a long critical notice of the work 3 was his first substantial philosophical publication. His later role in Vitters’s rejection of the Tractatus is acknowledged in the foreword to Philosophical Investigations 3. The posthumous canon has been a gold mine. An example: “Propositions” 9, reading the theoretical terms T, U, etc. of an axiomatized scientific theory as variables, sees the theory’s content as conveyed by a “Ramsey sentence” saying that for some T, U, etc., the theory’s axioms are true, a sentence in which all extralogical terms are observational. Another example: “General Propositions and Causality” 9, offering in a footnote the “Ramsey test” for acceptability of conditionals, i.e., add the if-clause to your ambient beliefs minimally modified to make the enlarged set self-consistent, and accept the conditional if the then-clause follows.  Refs: “Philosophical psychology,” in BANC. ‘

Ramée, philosopher who questioned the authority of Aristotle and influenced the methods of f semantics. He published his “Dialecticae institutiones libri XV,” reworked  as “Dialectique,”  the first philosophical work in what Grice (‘Gris’) calls ‘the vernacular.’ “Not much different, I should say – cf. Redecraft translating Logic!”  Ramée is appointed by François I as the first Regius Professor in Paris, where he teaches until he is  killed in the St. Bartholomew’s Day Massacre. Ramée doubted that we can apodictically intuit the major premises required for Aristotle’s rational syllogism. Turning instead to Plato, Ramée proposed that a “Socratizing” of logic would produce a more workable and fruitful result. As had Agricola and Sturm, Ramée reworks the rhetorical and liberal arts traditions’ concepts of “invention, judgment, and practice,” placing “method” in the center of judgment. Proceeding in these stages, we can “read” nature’s “arguments,” because they are modeled on natural reasoning, which in turn can emulate the reasoning by which God creates. Often Ramée’s results are depicted graphically in tables as in chapter IX of Hobbes’s Leviathan. When carefully done they would show both what is known and where gaps require further investigation; the process from invention to judgment is continuous.  Ramée’s works saw some 750 editions in one century, fostering the “Ramist” movement in emerging Protestant universities and the colonies. He influenced Bacon, Hobbes, Milton, Methodism, Cambridge Platonism, and Alsted. Inconsistencies make him less than a major figure in the history of logic, but his many works and their rapid popularity led to philosophical and educational efforts to bring the world of learning to the “plain man” by using the vernacular, and by more closely correlating the rigor of philosophy with the memorable and persuasive powers of rhetoric; he saw this goal as Socratic.

Rashdall: English historian, theologian, and personal idealist. While acknowledging that Berkeley needed to be corrected by Kant, Rashdall defended Berkeley’s thesis that objects only exist for minds. From this he concluded that there is a divine mind that guarantees the existence of nature and the objectivity of morality. In his most important philosophical work, The Theory of Good and Evil 7, Rashdall argued that actions are right or wrong according to whether they produce well-being, in which pleasure as well as a virtuous disposition are constituents. Rashdall coined the name ‘ideal utilitarianism’ for this view.

Illatum: rational choice: as oppose to irrational choice. V. choose. Grice, “Impicatures of ‘choosing’” “Hobson’s choice, or Hobson’s ‘choice’?” Pears on conversational implicaturum and choosing. That includes choosing in its meaning, and then it is easy to ac- cept the suggestion that choosing might be an S-factor, and that the hypothetical might be a Willkür: one of Grice’s favourite words from Kant – “It’s so Kantish!” I told Pears about this, and having found it’s cognate with English ‘choose,’ he immediately set to write an essay on the topic!” f., ‘option, discretion, caprice,’ from MidHG. willekür, f., ‘free choice, free will’; gee kiesen and Kur-.kiesen, verb, ‘to select,’ from Middle High German kiesen, Old High German chiosan, ‘to test, try, taste for the purpose of testing, test by tasting, select after strict examination.’ Gothic kiusan, Anglo-Saxon ceósan, English to choose. Teutonic root kus (with the change of s into rkur in the participle erkoren, see also Kur, ‘choice’), from pre-Teutonic gus, in Latin gus-tusgus-tare, Greek γεύω for γεύσω, Indian root juš, ‘to select, be fond of.’ Teutonic kausjun passed as kusiti into Slavonic. Insofar as a philosopher explains and predicts the actum as consequences of a choice, which are themselves explained in terms of alleged reasons, it must depict agents as to some extent rational. Rationality, like reasons, involves evaluation, and just as one can assess the rationality of individual choices, so one can assess the rationality of social choices and examine how they are and ought to be related to the preferences and judgments of the actor. In addition, there are intricate questions concerning rationality in ‘strategic’ situations in which outcomes depend on the choices of multiple individuals. Since rationality is a central concept in branches of philosophy such as Grice’s pragmatics, action theory, epistemology, ethics, and philosophy of mind, studies of rationality frequently cross the boundaries various branches of philosophy. The barebones theory of rationality  takes an agent’s preferences, i. e. his rankings of states of affairs, to be rational if they are complete and transitive, and it takes the agent’s choice to be rational if the agent does not prefer any feasible alternative to the one he chooses. Such a theory of rationality is clearly too weak. It says nothing about belief or what rationality implies when the agent does not know (with certainty) everything relevant to his choice. It may also be too strong, since there is nothing irrational about having incomplete preferences in situations involving uncertainty. Sometimes it is rational to suspend judgment and to refuse to rank alternatives that are not well understood. On the other hand, transitivity is a plausible condition, and the so-called “money pump” argument demonstrates that if one’s preferences are intransitive and one is willing to make exchanges, then one can be exploited. Suppose an agent A prefers X to YY to Z and Z to X, and that A will pay some small amount of money $P to exchange Y for XZ for Y, and X for Z. That means that, starting with ZA will pay $P for Y, then $P again for X, then $P again for Z and so on. An agent need not be this stupid. He will instead refuse to trade or adjust his preferences to eliminate the intransitivity. On the other hand, there is evidence that an agent’s preferences are not in fact transitive. Such evidence does not establish that transitivity is not a requirement of rationality. It may show instead that an agent may sometimes not be rational. In, e. g. the case of preference reversals,” it seems plausible that the agent in fact makes the ‘irrational choice.’ Evidence of persistent violations of transitivity is disquieting, since standards of rationality should not be impossibly high. A further difficulty with the barebones theory of rationality concerns the individuation of the objects of preference or choice. Consider e. g. data from a multi-stage ultimatum game. Suppose A can propose any division of $10 between A and BB can accept or reject A’s proposal. If B rejects the proposal, the amount of money drops to $5, and B gets to offer a division of the $5 which A can accept or reject. If A rejects B’s offer, both players get nothing. Suppose that A proposes to divide the money with $7 for A and $3 for BB declines and offers to split the $5 evenly, with $2.50 for each. Behaviour such as this is, in fact, common. Assuming that B prefers more money to less, these choices appear to be a violation of transitivity. B prefers $3 to $2.50, yet declines $3 for certain for $2.50 (with some slight chance of A declining and B getting nothing). But the objects of choice are not just quantities of money. B is turning down $3 as part of “a raw deal” in favour of $2.50 as part of a fair arrangement. If the objects of choice are defined in this way, there is no failure of transitivity. This plausible observation gives rise to a serious conceptual problem that Grice thinks he can solve. Unless there are constraints on how the objects of choice are individuated, conditions of rationality such as transitivity are empty. A’s choice of X over YY over Z and Z over X does not violate transitivity if “X when the alternative is Y” is not the same object of choice as “X when the alternative is Z”. A further substantive principle of rationality isrequired to limit how alternatives are individuated or to require that agents be indifferent between alternatives such as “X when the alternative is Y” and “X when the alternative is Z.” To extend the theory of rationality to circumstances involving risk (where the objects of choice are lotteries with known probabilities) and uncertainty (where agents do not know the probabilities or even all the possible outcomes of their choices) requires a further principle of rationality, as well as a controversial technical simplification. Subjective Bayesians suppose that the agent in circumstances of uncertainty has well-defined subjective probabilities (degrees of belief) over all the payoffs and thus that the objects of choice can be modeled as lotteries, just as in circumstances involving risk, though with subjective probabilities in place of objective probabilities. The most important of the axioms needed for the theory of rational choice under conditions of risk and uncertainty is the independence condition. The preferences of a rational agent between two lotteries that differ in only one outcome should match his preferences between the differing outcomes. A considerable part of Grice’s rational choice theory is concerned with formalizations of conditions of rationality and investigation of their implications. When they are complete and transitive and satisfy a further continuity condition, the agent’s preferences can be represented by an ordinal utility function, i. e. it is then possible to define a function that represents an agent’s preferences so that U(X) > U(Y) iff if the agent prefers X to Y, and U(X) = U(Y) iff if the agent is indifferent between X and Y. This function represents the preference ranking, and contains no information beyond the ranking. When in addition they satisfy the independence condition, the agent’s preferences can be represented by an expected utility function (Ramsey 1926). Such a function has two important properties. First, the expected utility of a lottery is equal to the sum of the expected utilities of its prizes weighted by their probabilities. Second, expected utility functions are unique up to a positive affine transformation. If U and V are both expected utility functions representing the preferences of an agent, for all objects of preference, XV(X) must be equal to aU(X) + b, where a and b are real numbers and a is positive. The axioms of rationality imply that the agent’s degrees of belief will satisfy the axioms of the probability calculus. A great deal of controversy surrounds Grice’s theory of rationality, and there have been many formal investigations into amendeding it. Although a conversational pair is very different from this agent and this other agent, the pair has a mechanism to evaluate alternatives and make a choice. The evaluation and the choice may be rational or irrational. Pace Grice’s fruitful seminars on rational helpfulness in cooperation, t is not, however, obvious, what principles of rationality should govern the choices and evaluations of the conversational dyad. Transitivity is one plausible condition. It seems that a conversational dyad that chooses X when faced with the alternatives X or YY when faced with the alternatives Y or Z and Z when faced with the alternatives X or Z, the conversational dyad has had “a change of hearts” or is choosing ‘irrationally.’ Yet, purported irrationalities such as these can easily arise from a standard mechanism that aims to link a ‘conversational choice’ and individual preferences. Suppose there are two conversationalists in the dyad. Individual One ranks the alternatives XYZ. Individual Two ranks them YZX. (An Individual Three if he comes by, may ranks them ZXY). If decisions are made by pairwise majority voting, X will be chosen from the pair (XY), Y will be chosen from (YZ), and Z will be chosen from (XZ). Clearly this is unsettling. But is a possible cycle in a ‘conversational choice’ “irrational”? Similar problems affect what one might call the logical coherence of a conversational judgment Suppose the dyad consists of two individuals who make the following judgments concerning the truth or falsity of the propositions P and Q and that “conversational” judgment follows the majority. P if P, Q Q Conversationalist A true true true Conversationalist B false true false (Conversationalist C, if he passes by) true false false “Conversation” as an Institution: true true false. The judgment of each conversationalist is consistent with the principles of logic, while the “conversational co-operative” judgment violates the principles of logic. The “cooperative conversational,” “altruistic,” “joint judgment” need not be consistent with the principles of egoist logic. Although conversational choice theory bears on questions of conversational rationality, most work in conversational choice theory explores the consequences of principles of rationality coupled with this or that explicitly practical, or meta-ethical constraint. Grice does not use ‘moral,’ since he distinguishes what he calls a ‘conversational maxim’ from a ‘moral maxim’ of the type Kant universalizes. Arrow’s impossibility theorem assumes that an individual preference and a concerted, joint preference are complete and transitive and that the method of forming a conversational, concerted, joint preference (or making a conversational, concerted, choice) issues in some joint preference ranking or joint choice for any possible profile (or dossier, as Grice prefers) of each individual preference. Arrow’s impossibility theorem imposes a weak UNANIMITY (one-soul) condition. If A and B prefers X to Y, Y must not jointly preferred. Arrow’s impossibility theorem requires that there be no boss (call him Immanuel, the Genitor) whose preference determines a joint preference or choice irrespective of the preferences of anybody else. Arrow’s impossibility theorem imposes the condition that the joint concerted conversational preference between X and Y should depend on how A and B rank X and Y and on nothing else. Arrow’s impossibility theorem proves that no method of co-relating or linking conversational and a monogogic preference can satisfy all these conditions. If an monopreference and a mono-evaluations both satisfy the axioms of expected utility theory (with shared or objective probabilities) and that a duo-preference conform to the unanimous mono-preference, a duo- evaluation is determined by a weighted sum of individual utilities. A form of weighted futilitarianism, which prioritizes the interests of the recipient, rather than the emissor, uniquely satisfies a longer list of rational and practical constraints. When there are instead disagreements in probability assignments, there is an impossibility result. The unanimity (‘one-soul’) condition implies that for some profiles of individual preferences, a joint or duo-evaluation will not satisfy the axioms of expected utility theory. When outcomes depend on what at least two autonomous free agents do, one agent’s best choice may depend on what the other agent chooses. Although the principles of rationality governing mono-choice still apply, there is a further principle of conversational rationality governing the ‘expectation’ (to use Grice’s favourite term) of the action (or conversational move) of one’s co-conversationalist (and obviously, via the mutuality requirement of applicational universalizability) of the co-conversationalist’s ‘expectation’ concerning the conversationalist’s action and expectation, and so forth. Grice’s Conversational Game Theory plays a protagonist role within philosophy, and it is relevant to inquiries concerning conversational rationality and inquiries concerning conversational ethics. Rational choice -- Probability -- Dutch book, a bet or combination of bets whereby the bettor is bound to suffer a net loss regardless of the outcome. A simple example would be a bet on a proposition p at odds of 3 : 2 combined with a bet on not-p at the same odds, the total amount of money at stake in each bet being five dollars. Under this arrangement, if p turned out to be true one would win two dollars by the first bet but lose three dollars by the second, and if p turned out to be false one would win two dollars by the second bet but lose three dollars by the first. Hence, whatever happened, one would lose a dollar.  Dutch book argument, the argument that a rational person’s degrees of belief must conform to the axioms of the probability calculus, since otherwise, by the Dutch book theorem, he would be vulnerable to a Dutch book. R.Ke. Dutch book theorem, the proposition that anyone who a counts a bet on a proposition p as fair if the odds correspond to his degree of belief that p is true and who b is willing to make any combination of bets he would regard individually as fair will be vulnerable to a Dutch book provided his degrees of belief do not conform to the axioms of the probability calculus. Thus, anyone of whom a and b are true and whose degree of belief in a disjunction of two incompatible propositions is not equal to the sum of his degrees of belief in the two propositions taken individually would be vulnerable to a Dutch book. Illatum: rational decision theory -- decidability, as a property of sets, the existence of an effective procedure a “decision procedure” which, when applied to any object, determines whether or not the object belongs to the set. A theory or logic is decidable if and only if the set of its theorems is. Decidability is proved by describing a decision procedure and showing that it works. The truth table method, for example, establishes that classical propositional logic is decidable. To prove that something is not decidable requires a more precise characterization of the notion of effective procedure. Using one such characterization for which there is ample evidence, Church proved that classical predicate logic is not decidable. decision theory, the theory of rational decision, often called “rational choice theory” in political science and other social sciences. The basic idea probably Pascal’s was published at the end of Arnaud’s Port-Royal Logic 1662: “To judge what one must do to obtain a good or avoid an evil one must consider not only the good and the evil in itself but also the probability of its happening or not happening, and view geometrically the proportion that all these things have together.” Where goods and evils are monetary, Daniel Bernoulli 1738 spelled the idea out in terms of expected utilities as figures of merit for actions, holding that “in the absence of the unusual, the utility resulting from a fixed small increase in wealth will be inversely proportional to the quantity of goods previously possessed.” This was meant to solve the St. Petersburg paradox: Peter tosses a coin . . . until it should land “heads” [on toss n]. . . . He agrees to give Paul one ducat if he gets “heads” on the very first throw [and] with each additional throw the number of ducats he must pay is doubled. . . . Although the standard calculation shows that the value of Paul’s expectation [of gain] is infinitely great [i.e., the sum of all possible gains $ probabilities, 2n/2 $ ½n], it has . . . to be admitted that any fairly reasonable man would sell his chance, with great pleasure, for twenty ducats. In this case Paul’s expectation of utility is indeed finite on Bernoulli’s assumption of inverse proportionality; but as Karl Menger observed 4, Bernoulli’s solution fails if payoffs are so large that utilities are inversely proportional to probabilities; then only boundedness of utility scales resolves the paradox. Bernoulli’s idea of diminishing marginal utility of wealth survived in the neoclassical texts of W. S. Jevons 1871, Alfred Marshall 0, and A. C. Pigou 0, where personal utility judgment was understood to cause preference. But in the 0s, operationalistic arguments of John Hicks and R. G. D. Allen persuaded economists that on the contrary, 1 utility is no cause but a description, in which 2 the numbers indicate preference order but not intensity. In their Theory of Games and Economic Behavior 6, John von Neumann and Oskar Morgenstern undid 2 by pushing 1 further: ordinal preferences among risky prospects were now seen to be describable on “interval” scales of subjective utility like the Fahrenheit and Celsius scales for temperature, so that once utilities, e.g., 0 and 1, are assigned to any prospect and any preferred one, utilities of all prospects are determined by overall preferences among gambles, i.e., probability distributions over prospects. Thus, the utility midpoint between two prospects is marked by the distribution assigning probability ½ to each. In fact, Ramsey had done that and more in a little-noticed essay “Truth and Probability,” 1 teasing subjective probabilities as well as utilities out of ordinal preferences among gambles. In a form independently invented by L. J. Savage Foundations of Statistics, 4, this approach is now widely accepted as a basis for rational decision analysis. The 8 book of that title by Howard Raiffa became a theoretical centerpiece of M.B.A. curricula, whose graduates diffused it through industry, government, and the military in a simplified format for defensible decision making, namely, “costbenefit analyses,” substituting expected numbers of dollars, deaths, etc., for preference-based expected utilities. Social choice and group decision form the native ground of interpersonal comparison of personal utilities. Thus, John C. Harsanyi 5 proved that if 1 individual and social preferences all satisfy the von Neumann-Morgenstern axioms, and 2 society is indifferent between two prospects whenever all individuals are, and 3 society prefers one prospect to another whenever someone does and nobody has the opposite preference, then social utilities are expressible as sums of individual utilities on interval scales obtained by stretching or compressing the individual scales by amounts determined by the social preferences. Arguably, the theorem shows how to derive interpersonal comparisons of individual preference intensities from social preference orderings that are thought to treat individual preferences on a par. Somewhat earlier, Kenneth Arrow had written that “interpersonal comparison of utilities has no meaning and, in fact, there is no meaning relevant to welfare economics in the measurability of individual utility” Social Choice and Individual Values, 1  a position later abandoned P. Laslett and W. G. Runciman, eds., Philosophy, Politics and Society, 7. Arrow’s “impossibility theorem” is illustrated by cyclic preferences observed by Condorcet in 1785 among candidates A, B, C of voters 1, 2, 3, who rank them ABC, BCA, CAB, respectively, in decreasing order of preference, so that majority rule yields intransitive preferences for the group of three, of whom two 1, 3 prefer A to B and two 1, 2 prefer B to C but two 2, 3 prefer C to A. In general, the theorem denies existence of technically democratic schemes for forming social preferences from citizens’ preferences. A clause tendentiously called “independence of irrelevant alternatives” in the definition of ‘democratic’ rules out appeal to preferences among non-candidates as a way to form social preferences among candidates, thus ruling out the preferences among gambles used in Harsanyi’s theorem. See John Broome, Weighing Goods, 1, for further information and references. Savage derived the agent’s probabilities for states as well as utilities for consequences from preferences among abstract acts, represented by deterministic assignments of consequences to states. An act’s place in the preference ordering is then reflected by its expected utility, a probability-weighted average of the utilities of its consequences in the various states. Savage’s states and consequences formed distinct sets, with every assignment of consequences to states constituting an act. While Ramsey had also taken acts to be functions from states to consequences, he took consequences to be propositions sets of states, and assigned utilities to states, not consequences. A further step in that direction represents acts, too, by propositions see Ethan Bolker, Functions Resembling Quotients of Measures,  Microfilms, 5; and Richard Jeffrey, The Logic of Decision, 5, 0. Bolker’s representation theorem states conditions under which preferences between truth of propositions determine probabilities and utilities nearly enough to make the position of a proposition in one’s preference ranking reflect its “desirability,” i.e., one’s expectation of utility conditionally on it. decision theory decision theory 208   208 Alongside such basic properties as transitivity and connexity, a workhorse among Savage’s assumptions was the “sure-thing principle”: Preferences among acts having the same consequences in certain states are unaffected by arbitrary changes in those consequences. This implies that agents see states as probabilistically independent of acts, and therefore implies that an act cannot be preferred to one that dominates it in the sense that the dominant act’s consequences in each state have utilities at least as great as the other’s. Unlike the sure thing principle, the principle ‘Choose so as to maximize CEU conditional expectation of utility’ rationalizes action aiming to enhance probabilities of preferred states of nature, as in quitting cigarettes to increase life expectancy. But as Nozick pointed out in 9, there are problems in which choiceworthiness goes by dominance rather than CEU, as when the smoker like R. A. Fisher in 9 believes that the statistical association between smoking and lung cancer is due to a genetic allele, possessors of which are more likely than others to smoke and to contract lung cancer, although among them smokers are not especially likely to contract lung cancer. In such “Newcomb” problems choices are ineffectual signs of conditions that agents would promote or prevent if they could. Causal decision theories modify the CEU formula to obtain figures of merit distinguishing causal efficacy from evidentiary significance  e.g., replacing conditional probabilities by probabilities of counterfactual conditionals; or forming a weighted average of CEU’s under all hypotheses about causes, with agents’ unconditional probabilities of hypotheses as weights; etc. Mathematical statisticians leery of subjective probability have cultivated Abraham Wald’s Theory of Statistical Decision Functions 0, treating statistical estimation, experimental design, and hypothesis testing as zero-sum “games against nature.” For an account of the opposite assimilation, of game theory to probabilistic decision theory, see Skyrms, Dynamics of Rational Deliberation 0. The “preference logics” of Sören Halldén, The Logic of ‘Better’ 7, and G. H. von Wright, The Logic of Preference 3, sidestep probability. Thus, Halldén holds that when truth of p is preferred to truth of q, falsity of q must be preferred to falsity of p, and von Wright with Aristotle holds that “this is more choiceworthy than that if this is choiceworthy without that, but that is not choiceworthy without this” Topics III, 118a. Both principles fail in the absence of special probabilistic assumptions, e.g., equiprobability of p with q. Received wisdom counts decision theory clearly false as a description of human behavior, seeing its proper status as normative. But some, notably Davidson, see the theory as constitutive of the very concept of preference, so that, e.g., preferences can no more be intransitive than propositions can be at once true and false.  Rational decision: envelope paradox, an apparent paradox in decision theory that runs as follows. You are shown two envelopes, M and N, and are reliably informed that each contains some finite positive amount of money, that the amount in one unspecified envelope is twice the amount in the unspecified other, and that you may choose only one. Call the amount in M ‘m’ and that in N ‘n’. It might seem that: there is a half chance that m % 2n and a half chance that m = n/2, so that the “expected value” of m is ½2n ! ½n/2 % 1.25n, so that you should prefer envelope M. But by similar reasoning it might seem that the expected value of n is 1.25m, so that you should prefer envelope N.  illatum. rationality – while Grice never used to employ ‘rationality’ he learned to! In “Retrospective epilogue” in fact he refers to the principle of conversational helpfulness as ‘promoting conversational rationality.’ Rationality as a faculty psychology, the view that the mind is a collection of departments responsible for distinct psychological functions. Related to faculty psychology is the doctrine of localization of function, wherein each faculty has a specific brain location. Faculty psychologies oppose theories of mind as a unity with one function e.g., those of Descartes and associationism or as a unity with various capabilities e.g., that of Ockham, and oppose the related holistic distributionist or mass-action theory of the brain. Faculty psychology began with Aristotle, who divided the human soul into five special senses, three inner senses common sense, imagination, memory and active and passive mind. In the Middle Ages e.g., Aquinas Aristotle’s three inner senses were subdivied, creating more elaborate lists of five to seven inward wits. Islamic physicianphilosophers such as Avicenna integrated Aristotelian faculty psychology with Galenic medicine by proposing brain locations for the faculties. Two important developments in faculty psychology occurred during the eighteenth century. First, Scottish philosophers led by Reid developed a version of faculty psychology opposed to the empiricist and associationist psychologies of Locke and Hume. The Scots proposed that humans were endowed by God with a set of faculties permitting knowledge of the world and morality. The Scottish system exerted considerable influence in the United States, where it was widely taught as a moral, character-building discipline, and in the nineteenth century this “Old Psychology” opposed the experimental “New Psychology.” Second, despite then being called a charlatan, Franz Joseph Gall 17581828 laid the foundation for modern neuropsychology in his work on localization of function. Gall rejected existing faculty psychologies as philosophical, unbiological, and incapable of accounting for everyday behavior. Gall proposed an innovative behavioral and biological list of faculties and brain localizations based on comparative anatomy, behavior study, and measurements of the human skull. Today, faculty psychology survives in trait and instinct theories of personality, Fodor’s theory that mental functions are implemented by neurologically “encapsulated” organs, and localizationist theories of the brain. rationalism, the position that reason has precedence over other ways of acquiring knowledge, or, more strongly, that it is the unique path to knowledge. It is most often encountered as a view in epistemology, where it is traditionally contrasted with empiricism, the view that the senses are primary with respect to knowledge. It is important here to distinguish empiricism with respect to knowledge from empiricism with respect to ideas or concepts; whereas the former is opposed to rationalism, the latter is opposed to the doctrine of innate ideas. The term is also encountered in the philosophy of religion, where it may designate those who oppose the view that revelation is central to religious knowledge; and in ethics, where it may designate those who oppose the view that ethical principles are grounded in or derive from emotion, empathy, or some other non-rational foundation. The term ‘rationalism’ does not generally designate a single precise philosophical position; there are several ways in which reason can have precedence, and several accounts of knowledge to which it may be opposed. Furthermore, the very term ‘reason’ is not altogether clear. Often it designates a faculty of the soul, distinct from sensation, imagination, and memory, which is the ground of a priori knowledge. But there are other conceptions of reason, such as the narrower conception in which Pascal opposes reason to “knowledge of the heart” Pensées, section 110, or the computational conception of reason Hobbes advances in Leviathan I.5. The term might thus be applied to a number of philosophical positions from the ancients down to the present. Among the ancients, ‘rationalism’ and ‘empiricism’ especially denote two schools of medicine, the former relying primarily on a theoretical knowledge of the hidden workings of the human body, the latter relying on direct clinical experience. The term might also be used to characterize the views of Plato and later Neoplatonists, who argued that we have pure intellectual access to the Forms and general principles that govern reality, and rejected sensory knowledge of the imperfect realization of those Forms in the material world. In recent philosophical writing, the term ‘rationalism’ is most closely associated with the positions of a group of seventeenth-century philosophers, Descartes, Spinoza, Leibniz, and sometimes Malebranche. These thinkers are often referred to collectively as the Continental rationalists, and are generally opposed to the socalled British empiricists, Locke, Berkeley, and Hume. All of the former share the view that we have a non-empirical and rational access to the truth about the way the world is, and all privilege reason over knowledge derived from the senses. These philosophers are also attracted to mathematics as a model for knowledge in general. But these common views are developed in quite different ways. Descartes claims to take his inspiration from mathematics  not mathematics as commonly understood, but the analysis of the ancients. According to Descartes, we start from first principles known directly by reason the cogito ergo sum of the Meditations, what he calls intuition in his Rules for the Direction of the Mind; all other knowledge is deduced from there. A central aim of his Meditations is to show that this faculty of reason is trustworthy. The senses, on the other hand, are generally deceptive, leading us to mistake sensory qualities for real qualities of extended bodies, and leading us to the false philosophy of Aristotle and to Scholasticism. Descartes does not reject the senses altogether; in Meditation VI he argues that the senses are most often correct in circumstances concerning the preservation of life. Perhaps paradoxically, experiment is important to Descartes’s scientific work. However, his primary interest is in the theoretical account of the phenomena experiment reveals, and while his position is unclear, he may have considered experiment as an auxiliary to intuition and deduction, or as a second-best method that can be used with problems too complex for pure reason. Malebranche, following Descartes, takes similar views in his Search after Truth, though unlike Descartes, he emphasizes original sin as the cause of our tendency to trust the senses. Spinoza’s model for knowledge is Euclidean geometry, as realized in the geometrical form of the Ethics. Spinoza explicitly argues that we cannot have adequate ideas of the world through sensation Ethics II, propositions 1631. In the Ethics he does see a role for the senses in what he calls knowledge of the first and knowledge of the second kinds, and in the earlier Emendation of the Intellect, he suggests that the senses may be auxiliary aids to genuine knowledge. But the senses are imperfect and far less valuable, according to Spinoza, than intuition, i.e., knowledge of the third kind, from which sensory experience is excluded. Spinoza’s rationalism is implicit in a central proposition of the Ethics, in accordance with which “the order and connection of ideas is the same as the order and connection of things” Ethics II, proposition 7, allowing one to infer causal connections between bodies and states of the material world directly from the logical connections between ideas. Leibniz, too, emphasizes reason over the senses in a number of ways. In his youth he believed that it would be possible to calculate the truth-value of every sentence by constructing a logical language whose structure mirrors the structure of relations between concepts in the world. This view is reflected in his mature thought in the doctrine that in every truth, the concept of the predicate is contained in the concept of the subject, so that if one could take the God’s-eye view which, he concedes, we cannot, one could determine the truth or falsity of any proposition without appeal to experience Discourse on Metaphysics, section 8. Leibniz also argues that all truths are based on two basic principles, the law of non-contradiction for necessary truths, and the principle of sufficient reason for contingent truths Monadology, section 31, both of which can be known a priori. And so, at least in principle, the truth-values of all propositions can be determined a priori. This reflects his practice in physics, where he derives a number of laws of motion from the principle of the equality of cause and effect, which can be known a priori on the basis of the principle of sufficient reason. But, at the same time, referring to the empirical school of ancient medicine, Leibniz concedes that “we are all mere Empirics in three fourths of our actions” Monadology, section 28. Each of the so-called Continental rationalists does, in his own way, privilege reason over the senses. But the common designation ‘Continental rationalism’ arose only much later, probably in the nineteenth century. For their contemporaries, more impressed with their differences than their common doctrines, the Continental rationalists did not form a single homogeneous school of thought. Illatum: rationality. In its primary sense, rationality is a normative concept that philosophers have generally tried to characterize in such a way that, for any action, belief, or desire, if it is rational we ought to choose it. No such positive characterization has achieved anything close to universal assent because, often, several competing actions, beliefs, or desires count as rational. Equating what is rational with what is rationally required eliminates the category of what is rationally allowed. Irrationality seems to be the more fundamental normative category; for although there are conflicting substantive accounts of irrationality, all agree that to say of an action, belief, or desire that it is irrational is to claim that it should always be avoided. Rationality is also a descriptive concept that refers to those intellectual capacities, usually involving the ability to use language, that distinguish persons from plants and most other animals. There is some dispute about whether some non-human animals, e.g., dolphins and chimpanzees, are rational in this sense. Theoretical rationality applies to beliefs. An irrational belief is one that obviously conflicts with what one should know. This characterization of an irrational belief is identical with the psychiatric characterization of a delusion. It is a personrelative concept, because what obviously conflicts with what should be known by one person need not obviously conflict with what should be known by another. On this account, any belief that is not irrational counts as rational. Many positive characterizations of rational beliefs have been proposed, e.g., 1 beliefs that are either self-evident or derived from self-evident beliefs by a reliable procedure and 2 beliefs that are consistent with the overwhelming majority of one’s beliefs; but all of these positive characterizations have encountered serious objections. Practical rationality applies to actions. For some philosophers it is identical to instrumental rationality. On this view, commonly called instrumentalism, acting rationally simply means acting in a way that is maximally efficient in achieving one’s goals. However, most philosophers realize that achieving one goal may conflict with achieving another, and therefore require that a rational action be one that best achieves one’s goals only when these goals are considered as forming a system. Others have added that all of these goals must be ones that would be chosen given complete knowledge and understanding of what it would be like to achieve these goals. On the latter account of rational action, the system of goals is chosen by all persons for themselves, and apart from consistency there is no external standpoint from which to evaluate rationally any such system. Thus, for a person with a certain system of goals it will be irrational to act morally. Another account of rational action is not at all person-relative. On this account, to act rationally is to act on universalizable principles, so that what is a reason for one person must be a reason for everyone. One point of such an account is to make it rationally required to act morally, thus making all immoral action irrational. However, if to call an action irrational is to claim that everyone would hold that it is always to be avoided, then it is neither irrational to act immorally in order to benefit oneself or one’s friends, nor irrational to act morally even when that goes against one’s system of goals. Only a negative characterization of what is rational as what is not irrational, which makes it rationally permissible to act either morally or in accordance with one’s own system of goals, as long as these goals meet some minimal objective standard, seems likely to be adequate.   Illatum: rationalization, 1 an apparent explanation of a person’s action or attitude by appeal to reasons that would justify or exculpate the person for it  if, contrary to fact, those reasons were to explain it; 2 an explanation or interpretation made from a rational perspective. In sense 1, rationalizations are pseudo-explanations, often motivated by a desire to exhibit an item in a favorable light. Such rationalizations sometimes involve self-deception. Depending on one’s view of justification, a rationalization might justify an action  by adducing excellent reasons for its performance  even if the agent, not having acted for those reasons, deserves no credit for so acting. In sense 2 a sense popularized in philosophy by Donald Davidson, rationalizations of intentional actions are genuine explanations in terms of agents’ reasons. In this sense, we provide a rationalization for  or “rationalize”  Robert’s shopping at Zed’s by identifying the reasons for which he does so: e.g., he wants to buy an excellent kitchen knife and believes that Zed’s sells the best cutlery in town. Also, the reasons for which an agent acts may themselves be said to rationalize the action. Beliefs, desires, and intentions may be similarly rationalized. In each case, a rationalization exhibits the rationalized item as, to some degree, rational from the standpoint of the person to whom it is attributed. rational psychology, the a priori study of the mind. This was a large component of eighteenthand nineteenth-century psychology, and was contrasted by its exponents with empirical psychology, which is rooted in contingent experience. The term ‘rational psychology’ may also designate a mind, or form of mind, having the property of rationality. Current philosophy of mind includes much discussion of rational psychologies, but the notion is apparently ambiguous. On one hand, there is rationality as intelligibility. This is a minimal coherence, say of desires or inferences, that a mind must possess to be a mind. For instance, Donald Davidson, many functionalists, and some decision theorists believe there are principles of rationality of this sort that constrain the appropriate attribution of beliefs and desires to a person, so that a mind must meet such constraints if it is to have beliefs and desires. On another pole, there is rationality as justification. For someone’s psychology to have this property is for that psychology to be as reason requires it to be, say for that person’s inferences and desires to be supported by proper reasons given their proper weight, and hence to be justified. Rationality as justification is a normative property, which it would seem some minds lack. But despite the apparent differences between these two sorts of rationality, some important work in philosophy of mind implies either that these two senses in fact collapse, or at least that there are intervening and significant senses, so that things at least a lot like normative principles constrain what our psychologies are.  rational reconstruction, also called logical reconstruction, translation of a discourse of a certain conceptual type into a discourse of another conceptual type with the aim of making it possible to say everything or everything important that is expressible in the former more clearly or perspicuously in the latter. The best-known example is one in Carnap’s Der Logische Aufbau der Welt. Carnap attempted to translate discourse concerning physical objects e.g., ‘There is a round brown table’ into discourse concerning immediate objects of sense experience ‘Color patches of such-and-such chromatic characteristics and shape appear in such-and-such a way’. He was motivated by the empiricist doctrine that immediate sense experience is conceptually prior to everything else, including our notion of a physical object. In addition to talk of immediate sense experience, Carnap relied on logic and set theory. Since their use is difficult to reconcile with strict empiricism, his translation would not have fully vindicated empiricism even if it had succeeded.  Illatum: rationality -- reasons for action, considerations that call for or justify action. They may be subjective or objective. A subjective reason is a consideration an agent understands to support a course of action, whether or not it actually does. An objective reason is one that does support a course of action, regardless of whether the agent realizes it. What are cited as reasons may be matters either of fact or of value, but when facts are cited values are also relevant. Thus the fact that cigarette smoke contains nicotine is a reason for not smoking only because nicotine has undesirable effects. The most important evaluative reasons are normative reasons  i.e., considerations having e.g. ethical force. Facts become obligating reasons when, in conjunction with normative considerations, they give rise to an obligation. Thus in view of the obligation to help the needy, the fact that others are hungry is an obligating reason to see they are fed. Reasons for action enter practical thinking as the contents of beliefs, desires, and other mental states. But not all the reasons one has need motivate the corresponding behavior. Thus I may recognize an obligation to pay taxes, yet do so only for fear of punishment. If so, then only my fear is an explaining reason for my action. An overriding reason is one that takes precedence over all others. It is often claimed that moral reasons override all others objectively, and should do so subjectively as well. Finally, one may speak of an all-things-considered reason  one that after due consideration is taken as finally determinative of what shall be done.    reasons for belief, roughly, bases of belief. The word ‘belief’ is commonly used to designate both a particular sort of psychological state, a state of believing, and a particular intentional content or proposition believed. Reasons for belief exhibit an analogous duality. A proposition, p, might be said to provide a normative reason to believe a proposition, q, for instance, when p bears some appropriate warranting relation to q. And p might afford a perfectly good reason to believe q, even though no one, as a matter of fact, believes either p or q. In contrast, p is a reason that I have for believing q, if I believe p and p counts as a reason in the sense above to believe q. Undoubtedly, I have reason to believe countless propositions that I shall never, as it happens, come to believe. Suppose, however, that p is a reason for which I believe q. In that case, I must believe both p and q, and p must be a reason to believe q  or, at any rate, I must regard it as such. It may be that I must, in addition, believe q at least in part because I believe p. Reasons in these senses are inevitably epistemic; they turn on considerations of evidence, truth-conduciveness, and the like. But not all reasons for belief are of this sort. An explanatory reason, a reason why I believe p, may simply be an explanation for my having or coming to have this belief. Perhaps I believe p because I was brainwashed, or struck on the head, or because I have strong non-epistemic motives for this belief. I might, of course, hold the belief on the basis of unexceptionable epistemic grounds. When this is so, my believing p may both warrant and explain my believing q. Reflections of this sort can lead to questions concerning the overall or “all-things-considered” reasonableness of a given belief. Some philosophers e.g., Clifford argue that a belief’s reasonableness depends exclusively on its epistemic standing: my believing p is reasonable for me provided it is epistemically reasonable for me; where belief is concerned, epistemic reasons are overriding. Others, siding with James, have focused on the role of belief in our psychological economy, arguing that the reasonableness of my holding a given belief can be affected by a variety of non-epistemic considerations. Suppose I have some evidence that p is false, but that I stand to benefit in a significant way from coming to believe p. If that is so, and if the practical advantages of my holding p considerably outweigh the practical disadvantages, it might seem obvious that my holding p is reasonable for me in some all-embracing sense. 

Ray, J. English naturalist whose work on the structure and habits of plants and animals led to important conclusions on the methodology of classification and gave a strong impetus to the design argument in natural theology. In an early paper he argued that the determining characteristics of a species are those transmitted by seed, since color, scent, size, etc., vary with climate and nutriment. Parallels from the animal kingdom suggested the correct basis for classification would be structural. But we have no knowledge of real essences. Our experience of nature is of a continuum, and for practical purposes kinships are best identified by a plurality of criteria. His mature theory is set out in Dissertatio Brevis 1696 and Methodus Emendata 1703. The Wisdom of God Manifested in the Works of the Creation 1691 and three revisions was a best-selling compendium of Ray’s own scientific learning and was imitated and quarried by many later exponents of the design argument. Philosophically, he relied on others, from Cicero to Cudworth, and was superseded by Paley.

Res: “Possibly the most important word in philosophy.” Grice -- Realism – causal realism -- direct realism, the theory that perceiving is epistemically direct, unmediated by conscious or unconscious inference. Direct realism is distinguished, on the one hand, from indirect, or representative, realism, the view that perceptual awareness of material objects is mediated by an awareness of sensory representations, and, on the other hand, from forms of phenomenalism that identify material objects with states of mind. It might be thought that direct realism is incompatible with causal theories of perception. Such theories invoke causal chains leading from objects perceived causes to perceptual states of perceivers effects. Since effects must be distinct from causes, the relation between an instance of perceiving and an object perceived, it would seem, cannot be direct. This, however, confuses epistemic directness with causal directness. A direct realist need only be committed to the former. In perceiving a tomato to be red, the content of my perceptual awareness is the tomato’s being red. I enter this state as a result of a complex causal process, perhaps. But my perception may be direct in the sense that it is unmediated by an awareness of a representational sensory state from which I am led to an awareness of the tomato. Perceptual error, and more particularly, hallucinations and illusions, are usually thought to pose special difficulties for direct realists. My hallucinating a red tomato, for instance, is not my being directly aware of a red tomato, since I may hallucinate the tomato even when none is present. Perhaps, then, my hallucinating a red tomato is partly a matter of my being directly aware of a round, red sensory representation. And if my awareness in this case is indistinguishable from my perception of an actual red tomato, why not suppose that I am aware of a sensory representation in the veridical case as well? A direct realist may respond by denying that hallucinations are in fact indistinguishable from veridical perceivings or by calling into question the claim that, if sensory representations are required to explain hallucinations, they need be postulated in the veridical case.  reality, in standard philosophical usage, how things actually are, in contrast with their mere appearance. Appearance has to do with how things seem to a particular perceiver or group of perceivers. Reality is sometimes said to be twoway-independent of appearance. This means that appearance does not determine reality. First, no matter how much agreement there is, based on appearance, about the nature of reality, it is always conceivable that reality differs from appearance. Secondly, appearances are in no way required for reality: reality can outstrip the range of all investigations that we are in a position to make. It may be that reality always brings with it the possibility of appearances, in the counterfactual sense that if there were observers suitably situated, then if conditions were not conducive to error, they would have experiences of such-and-such a kind. But the truth of such a counterfactual seems to be grounded in the facts of reality. Phenomenalism holds, to the contrary, that the facts of reality can be explained by such counterfactuals, but phenomenalists have failed to produce adequate non-circular analyses. The concept of reality on which it is two-wayindependent of experience is sometimes called objective reality. However, Descartes used this phrase differently, to effect a contrast with formal or actual reality. He held that there must be at least as much reality in the efficient and total cause of an effect as in the effect itself, and applied this principle as follows: “There must be at least as much actual or formal reality in the efficient and total cause of an idea as objective reality in the idea itself.” The objective reality of an idea seems to have to do with its having representational content, while actual or formal reality has to do with existence independent of the mind. Thus the quoted principle relates features of the cause of an idea to the representational content of the idea. Descartes’s main intended applications were to God and material objects. 

recursum: Grice, ‘anti-sneak.” The third clause (III) in Grice’s final analysis of utterer’s meaning is self-referential and recursive, in a good way, in that (III) itself counts as one of the ‘inference elements’ (that Grice symbolises as “E”) that (III) specifies. Grice loved the heraldy metaphor of the escrutcheon – and the Droste effect. Cf. ‘speculative,’ --.  Refs.: Luigi Speranza, “Grice’s mise-en-abyme,” per il Club Anglo-Italiano, The Swimming-Pool Library, Villa Grice, Liguria, Italia. Then there is the recursive function theory, an area of formal semantics that takes as its point of departure the study of an extremely limited class of functions, the recursive functions. Recursive function theory is a branch of higher arithmetic number theory, or the theory of natural numbers whose universe of discourse is restricted to the non-negative integers: 0, 1, 2, etc. However, the techniques and results of recursive function theory do not resemble those traditionally associated with number theory. The class of recursive functions is defined in a way that makes evident that every recursive function can be computed or calculated. The hypothesis that every calculable function is recursive, which is known as Church’s thesis, is often taken as a kind of axiom in recursive function theory. This theory has played an important role in philosophy of mathematics, especially when epistemological issues are studied, since as Grice knows, super-knowing may be hard, but not impossible!

Redintegratum: a psychological process, similar to or involving classical conditioning, in which one feature of a situation causes a person to recall, visualize, or recompose an entire original situation. On opening a pack of cigarettes, a person may visualize the entire process, including striking the match, lighting the cigarette, and puffing. Redintegration is used as a technique in behavior therapy, e.g. when someone trying to refrain from smoking is exposed to unpleasant odors and vivid pictures of lungs caked with cancer, and then permitted to smoke. If the unpleasantness of the odors and visualization outweighs the reinforcement of smoking, the person may resist smoking. Philosophically, for Grice, so-called barbarically “redintegratum” is of interest for two reasons. First, the process may be critical in prudence. By bringing long-range consequences of behavior into focus in present deliberation, redintegration may help to protect long-range interests. Second, redintegration offers a role for visual images in producing behavior. Images figure in paradigmatic cases of redintegration. In recollecting pictures of cancerous lungs, the person may refrain from smoking. Pears: “Oddly, it didn’t work with Grice who remained a  bit of a chain-smoker – but of Navy’s Cut only, except for the very last. He never smelt the odour in a bad way.”

reduction, the replacement of one expression by a second expression that differs from the first in prima facie reference. So-called reductions have been meant in the sense of uniformly applicable explicit definitions, contextual definitions, or replacements suitable only in a limited range of contexts. Thus, authors have spoken of reductive conceptual analyses, especially in the early days of analytic philosophy. In particular, in the sensedatum theory talk of physical objects was supposed to be reduced to talk of sense-data by explicit definitions or other forms of conceptual analysis. Logical positivists talked of the reduction of theoretical vocabulary to an observational vocabulary, first by explicit definitions, and later by other devices, such as Carnap’s reduction sentences. These appealed to a test condition predicate, T e.g., ‘is placed in water’, and a display predicate, D e.g., ‘dissolves’, to introduce a dispositional or other “non-observational” term, S e.g., ‘is water-soluble’: Ex [Tx / Dx / Sx], with ‘/’ representing the material conditional. Negative reduction sentences for non-occurrence of S took the form Ex [NTx / NDx / - Sx]. For coinciding predicate pairs T and TD and -D and ND Carnap referred to bilateral reduction sentences: Ex [Tx / Dx S Sx]. Like so many other attempted reductions, reduction sentences did not achieve replacement of the “reduced” term, S, since they do not fix application of S when the test condition, T, fails to apply. In the philosophy of mathematics, logicism claimed that all of mathematics could be reduced to logic, i.e., all mathematical terms could be defined with the vocabulary of logic and all theorems of mathematics could be derived from the laws of logic supplemented by these definitions. Russell’s Principia Mathematica carried out much of such a program with a reductive base of something much more like what we now call set theory rather than logic, strictly conceived. Many now accept the reducibility of mathematics to set theory, but only in a sense in which reductions are not unique. For example, the natural numbers can equally well be modeled as classes of equinumerous sets or as von Neumann ordinals. This non-uniqueness creates serious difficulties, with suggestions that set-theoretic reductions can throw light on what numbers and other mathematical objects “really are.” In contrast, we take scientific theories to tell us, unequivocally, that water is H20 and that temperature is mean translational kinetic energy. Accounts of theory reduction in science attempt to analyze the circumstance in which a “reducing theory” appears to tell us the composition of objects or properties described by a “reduced theory.” The simplest accounts follow the general pattern of reduction: one provides “identity statements” or “bridge laws,” with at least the form of explicit definitions, for all terms in the reduced theory not already appearing in the reducing theory; and then one argues that the reduced theory can be deduced from the reducing theory augmented by the definitions. For example, the laws of thermodynamics are said to be deducible from those of statistical mechanics, together with statements such as ‘temperature is mean translational kinetic energy’ and ‘pressure is mean momentum transfer’. How should the identity statements or bridge laws be understood? It takes empirical investigation to confirm statements such as that temperature is mean translational kinetic energy. Consequently, some have argued, such statements at best constitute contingent correlations rather than strict identities. On the other hand, if the relevant terms and their extensions are not mediated by analytic definitions, the identity statements may be analogized to identities involving two names, such as ‘Cicero is Tully’, where it takes empirical investigation to establish that the two names happen to have the same referent. One can generalize the idea of theory reduction in a variety of ways. One may require the bridge laws to suffice for the deduction of the reduced from the reducing theory without requiring that the bridge laws take the form of explicit identity statements or biconditional correlations. Some authors have also focused on the fact that in practice a reducing theory T2 corrects or refines the reduced theory T1, so that it is really only a correction or refinement, T1*, that is deducible from T2 and the bridge laws. Some have consequently applied the term ‘reduction’ to any pair of theories where the second corrects and extends the first in ways that explain both why the first theory was as accurate as it was and why it made the errors that it did. In this extended sense, relativity is said to reduce Newtonian mechanics. Do the social sciences, especially psychology, in principle reduce to physics? This prospect would support the so-called identity theory of mind and body, in particular resolving important problems in the philosophy of mind, such as the mindbody problem and the problem of other minds. Many though by no means all are now skeptical about the prospects for identifying mental properties, and the properties of other special sciences, with complex physical properties. To illustrate with an example from economics adapted from Fodor, in the right circumstances just about any physical object could count as a piece of money. Thus prospects seem dim for finding a closed and finite statement of the form ‘being a piece of money is . . .’, with only predicates from physics appearing on the right though some would want to admit infinite definitions in providing reductions. Similarly, one suspects that attributes, such as pain, are at best functional properties with indefinitely many possible physical realizations. Believing that reductions by finitely stable definitions are thus out of reach, many authors have tried to express the view that mental properties are still somehow physical by saying that they nonetheless supervene on the physical properties of the organisms that have them. In fact, these same difficulties that affect mental properties affect the paradigm case of temperature, and probably all putative examples of theoretical reduction. Temperature is mean translational temperature only in gases, and only idealized ones at that. In other substances, quite different physical mechanisms realize temperature. Temperature is more accurately described as a functional property, having to do with the mechanism of heat transfer between bodies, where, in principle, the required mechanism could be physically realized in indefinitely many ways. In most and quite possibly all cases of putative theory reduction by strict identities, we have instead a relation of physical realization, constitution, or instantiation, nicely illustrated by the property of being a calculator example taken from Cummins. The property of being a calculator can be physically realized by an abacus, by devices with gears and levers, by ones with vacuum tubes or silicon chips, and, in the right circumstances, by indefinitely many other physical arrangements. Perhaps many who have used ‘reduction’, particularly in the sciences, have intended the term in this sense of physical realization rather than one of strict identity. Let us restrict attention to properties that reduce in the sense of having a physical realization, as in the cases of being a calculator, having a certain temperature, and being a piece of money. Whether or not an object counts as having properties such as these will depend, not only on the physical properties of that object, but on various circumstances of the context. Intensions of relevant language users constitute a plausible candidate for relevant circumstances. In at least many cases, dependence on context arises because the property constitutes a functional property, where the relevant functional system calculational practices, heat transfer, monetary systems are much larger than the propertybearing object in question. These examples raise the question of whether many and perhaps all mental properties depend ineliminably on relations to things outside the organisms that have the mental properties.  Then there is the reduction sentence, for a given predicate Q3 of space-time points in a first-order language, any universal sentence S1 of the form: x [Q1x / Q2x / Q3 x], provided that the predicates Q1 and Q2 are consistently applicable to the same space-time points. If S1 has the form given above and S2 is of the form x [Q4x / Q5 / - Q6] and either S1 is a reduction sentence for Q3 or S2 is a reduction sentence for -Q3, the pair {S1, S2} is a reduction pair for Q3. If Q1 % Q4 and Q2 % - Q5, the conjunction of S1 and S2 is equivalent to a bilateral reduction sentence for Q3 of the form x [Q1 / Q3 S Q2]. These concepts were introduced by Carnap in “Testability and Meaning,” Philosophy of Science 637, to modify the verifiability criterion of meaning to a confirmability condition where terms can be introduced into meaningful scientific discourse by chains of reduction pairs rather than by definitions. The incentive for this modification seems to have been to accommodate the use of disposition predicates in scientific discourse. Carnap proposed explicating a disposition predicate Q3 by bilateral reduction sentences for Q3. An important but controversial feature of Carnap’s approach is that it avoids appeal to nonextensional conditionals in explicating disposition predicates.  Then there is the reductio ad absurdum, “Tertullian’s favourite proof,” – Grice. 1 The principles A / - A / -A and -A / A / A. 2 The argument forms ‘If A then B and not-B; therefore, not-A’ and ‘If not-A then B and not-B; therefore, A’ and arguments of these forms. Reasoning via such arguments is known as the method of indirect proof. 3 The rules of inference that permit i inferring not-A having derived a contradiction from A and ii inferring A having derived a contradiction from not-A. Both rules hold in classical logic and come to the same thing in any logic with the law of double negation. In intuitionist logic, however, i holds but ii does not. reductionism: The issue of reductionism is very much twentieth-century. There was Wisdom’s boring contribtions to Mind on ‘logical construction,’ Grice read the summary from Broad. One of the twelve –isms that Grice finds on his ascent to the City of Eternal Truth. He makes the reductive-reductionist distinction. Against J. M. Rountree. So, for Grice, the bad heathen vicious Reductionism can be defeated by the good Christian virtuous. Reductivism. A reductivist tries to define, say, what an emissor communicates (that p) in terms of the content of that proposition that he intends to transmit to his recipient. Following Aristotle, Grice reduces the effect to a ‘pathemata psucheos,’ i. e. a passio of the anima, as Boethius translates. This can be desiderative (“Thou shalt not kill”) or creditativa (“The grass is green.”)


mise-en-abyme-- reflection principles, two varieties of internal statements related to correctness in formal axiomatic systems. 1 Proof-theoretic reflection principles are formulated for effectively presented systems S that contain a modicum of elementary number theory sufficient to arithmetize their own syntactic notions, as done by Kurt Gödel in his 1 work on incompleteness. Let ProvS x express that x is the Gödel number of a statement provable in S, and let nA be the number of A, for any statement A of S. The weakest reflection principle considered for S is the collection RfnS of all statements of the form ProvS nA P A, which express that if A is provable from S then A is true. The proposition ConS expressing the consistency of S is a consequence of RfnS obtained by taking A to be a disprovable statement. Thus, by Gödel’s second incompleteness theorem, RfnS is stronger than S if S is consistent. Reflection principles are used in the construction of ordinal logics as a systematic means of overcoming incompleteness. 2 Set-theoretic reflection principles are formulated for systems S of axiomatic set theory, such as ZF Zermelo-Fraenkel. In the simplest form they express that any property A in the language of S that holds of the universe of “all” sets, already holds of a portion of that universe coextensive with some set x. This takes the form A P DxAx where in Ax all quantifiers of A are relativized to x. In contrast to proof-theoretic reflection principles, these may be established as theorems of ZF. 

Reflectum -- reflective equilibrium, as usually conceived, a coherence method for justifying evaluative principles and theories. The method was first described by Goodman, who proposed it be used to justify deductive and inductive principles. According to Goodman Fact, Fiction and Forecast, 5, a particular deductive inference is justified by its conforming with deductive principles, but these principles are justified in their turn by conforming with accepted deductive practice. The idea, then, is that justified inferences and principles are those that emerge from a process of mutual adjustment, with principles being revised when they sanction inferences we cannot bring ourselves to accept, and particular inferences being rejected when they conflict with rules we are unwilling to revise. Thus, neither principles nor particular inferences are epistemically privileged. At least in principle, everything is liable to revision. Rawls further articulated the method of reflective equilibrium and applied it in ethics. According to Rawls A Theory of Justice, 1, inquiry begins with considered moral judgments, i.e., judgments about which we are confident and which are free from common sources of error, e.g., ignorance of facts, insufficient reflection, or emotional agitation. According to narrow reflective equilibrium, ethical principles are justified by bringing them into coherence with our considered moral judgments through a process of mutual adjustment. Rawls, however, pursues a wide reflective equilibrium. Wide equilibrium is attained by proceeding to consider alternatives to the moral conception accepted in narrow equilibrium, along with philosophical arguments that might decide among these conceptions. The principles and considered judgments accepted in narrow equilibrium are then adjusted as seems appropriate. One way to conceive of wide reflective equilibrium is as an effort to construct a coherent system of belief by a process of mutual adjustment to considered moral judgments and moral principles as in narrow equilibrium along with the background philosophical, social scientific, and any other relevant beliefs that might figure in the arguments for and against alternative moral conceptions, e.g., metaphysical views regarding the nature of persons. As in Goodman’s original proposal, none of the judgments, principles, or theories involved is privileged: all are open to revision. 

regressus vitiosum -- viscious regress – Grice preferred ‘vicious circle’ versus ‘virtuous circle’ – “Whether virtuous regress sounds oxymoronic” -- regress that is in some way unacceptable, where a regress is an infinite series of items each of which is in some sense dependent on a prior item of a similar sort, e.g. an infinite series of events each of which is caused by the next prior event in the series. Reasons for holding a regress to be vicious might be that it is either impossible or that its existence is inconsistent with things known to be true. The claim that something would lead to a vicious regress is often made as part of a reductio ad absurdum argument strategy. An example of this can be found in Aquinas’s argument for the existence of an uncaused cause on the ground that an infinite regress of causes is vicious. Those responding to the argument have sometimes contended that this regress is not in fact vicious and hence that the argument fails. A more convincing example of a regress is generated by the principle that one’s coming to know the meaning of a word must always be based on a prior understanding of other words. If this principle is correct, then one can know the meaning of a word w1 only on the basis of previously understanding the meanings of other words w2 and w3. But a further application of the principle yields the result that one can understand these words w2 and w3 only on the basis of understanding still other words. This leads to an infinite regress. Since no one understands any words at birth, the regress implies that no one ever comes to understand any words. But this is clearly false. Since the existence of this regress is inconsistent with an obvious truth, we may conclude that the regress is vicious and consequently that the principle that generates it is false. 

Griceian renaissance – (“rinascimento”) after J. L. Austin’s death -- Erasmus, D., philosopher who played an important role in Renaissance humanism. Like his  forerunners Petrarch, Coluccio Salutati, Lorenzo Valla, Leonardo Bruni, and others, Erasmus stressed within philosophy and theology the function of philological precision, grammatical correctness, and rhetorical elegance. But for Erasmus the virtues of bonae literarae which are cultivated by the study of authors of Latin and Grecian antiquity must be decisively linked with Christian spirituality. Erasmus has been called by Huizinga the first modern intellectual because he tried to influence and reform the mentality of society by working within the shadow of ecclesiastical and political leaders. He epistemology, evolutionary Erasmus, Desiderius 278   278 became one of the first humanists to make efficient use of the then new medium of printing. His writings embrace various forms, including diatribe, oration, locution, comment, dialogue, and letter. After studying in Christian schools and living for a time in the monastery of Steyn near Gouda in the Netherlands, Erasmus worked for different patrons. He gained a post as secretary to the bishop of Kamerijk, during which time he wrote his first published book, the Adagia first edition 1500, a collection of annotated Latin adages. Erasmus was an adviser to the Emperor Charles V, to whom he dedicated his Institutio principii christiani 1516. After studies at the  of Paris, where he attended lectures by the humanist Faber Stapulensis, Erasmus was put in touch by his patron Lord Mountjoy with the British humanists John Colet and Thomas More. Erasmus led a restless life, residing in several European cities including London, Louvain, Basel, Freiburg, Bologna, Turin where he was awarded a doctorate of theology in 1506, and Rome. By using the means of modern philology, which led to the ideal of the bonae literarae, Erasmus tried to reform the Christian-influenced mentality of his times. Inspired by Valla’s Annotationes to the New Testament, he completed a new Latin translation of the New Testament, edited the writings of the early church fathers, especially St. Hieronymus, and wrote several commentaries on psalms. He tried to regenerate the spirit of early Christianity by laying bare its original sense against the background of scholastic interpretation. In his view, the rituals of the existing church blocked the development of an authentic Christian spirituality. Though Erasmus shared with Luther a critical approach toward the existing church, he did not side with the Reformation. His Diatribe de libero arbitrio 1524, in which he pleaded for the free will of man, was answered by Luther’s De servo arbitrio. The historically most influential books of Erasmus were Enchirion militis christiani 1503, in which he attacked hirelings and soldiers; the Encomium moriae id est Laus stultitiae 1511, a satire on modern life and the ecclesiastical pillars of society; and the sketches of human life, the Colloquia first published in 1518, often enlarged until 1553. In the small book Querela pacis 1517, he rejected the ideology of justified wars propounded by Augustine and Aquinas. Against the madness of war Erasmus appealed to the virtues of tolerance, friendliness, and gentleness. All these virtues were for him the essence of Christianity. 

Regressus: regression analysis, a part of statistical theory concerned with the analysis of data with the aim of inferring a linear functional relationship between assumed independent “regressor” variables and a dependent “response” variable. A typical example involves the dependence of crop yield on the application of fertilizer. For the most part, higher amounts of fertilizer are associated with higher yields. But typically, if crop yield is plotted vertically on a graph with the horizontal axis representing amount of fertilizer applied, the resulting points will not fall in a straight line. This can be due either to random “stochastic” fluctuations involving measurement errors, irreproducible conditions, or physical indeterminism or to failure to take into account other relevant independent variables such as amount of rainfall. In any case, from any resulting “scatter diagram,” it is possible mathematically to infer a “best-fitting” line. One method is, roughly, to find the line that minimizes the average absolute distance between a line and the data points collected. More commonly, the average of the squares of these distances is minimized this is the “least squares” method. If more than one independent variable is suspected, the theory of multiple regression, which takes into account multiple regressors, can be applied: this can help to minimize an “error term” involved in regression. Computers must be used for the complex computations typically encountered. Care must be taken in connection with the possibility that a lawlike, causal dependence is not really linear even approximately over all ranges of the regressor variables e.g., in certain ranges of amounts of application, more fertilizer is good for a plant, but too much is bad. 

reichenbach, “’philosopher,’ as we might say,” -- Grice of science and a major leader of the movement known as logical empiricism. Born in Hamburg, Reichenbach studies engineering (“if that’s something you study than learn” – Grice) for a brief time, then turned to mathematics, philosophy, and physics, which he pursued at Berlin, Munich, and Göttingen (“He kept moving in the area.”) He takes his doctorate in philosophy at Erlangen with a dissertation on conceptual aspects of probability, and a degree in mathematics and physics by state examination at Göttingen – “just in case,” he said. With Hitler’s rise to power, Reichenbach flees to Istanbul, then to “Los Angeles,” a town on the western coast of America -- where he remained until his death, “if not after” (Grice). Prior to his departure from G.y he is  professor of philosophy of science at the  of Berlin, leader of the Berlin Group of logical empiricists, and a close associate of Einstein. With Carnap Reichenbach founds “Erkenntnis,” the major journal of scientific philosophy before World War II. After a short period early in his career as a follower of Kant, Reichenbach rejects, “slightly out of the blue” (Grice),  the synthetic a priori, chiefly because of considerations arising out of Einstein’s general theory of relativity. Reichenbach remains  thereafter champion of empiricism, adhering to a probabilistic version of the verifiability theory of cognitive (“if not emotive”) meaning. Never, however, did he embrace the logical positivism of what he pompously called the “Wiener Kraus.” Ideed, he explicitly described his principal epistemological work, Experience and Prediction 8, as his refutation of logical positivism. In particular, his logical empiricism consisted in rejecting phenomenalism in favor of physicalism; he rejected phenomenalism both in embracing scientific realism and in insisting on a thoroughgoing probabilistic analysis of scientific meaning and scientific knowledge. His main works span a wide range. In Probability and Induction he advocated the frequency interpretation of probability and offered a pragmatic justification of induction. In his philosophy of space and time he defended conventionality of geometry and of simultaneity. In foundations of quantum mechanics he adopted a three-valued logic to deal with causal anomalies. He wrote major works on epistemology, logic, laws of nature, counterfactuals, and modalities. At the time of his death he had almost completed The Direction of Time, which was published posthumously. Grice cites him profusely in “Actions and events.” Refs.: Section on Reichenbach in Grice, “Actions and events.”

reid: Scots philosopher, beloved by Woozley, Grice’s friend at Oxford in the late 1930s. Adefender of common sense and critic of the theory of impressions and ideas articulated by Hume. Reid was born exactly one year before Hume, in Strachan, Scotland. A bright lad, he went to Marischal  in Aberdeen at the age of twelve, studying there with Thomas Blackwell and George Turnbull. The latter apparently had great influence on Reid. Turnbull contended that knowledge of the facts of sense and introspection may not be overturned by reasoning and that volition is the only active power known from experience. Turnbull defended common sense under the cloak of Berkeley. Reid threw off that cloak with considerable panache, but he took over the defense of common sense from Turnbull. Reid moved to a position of regent and lecturer at King’s  in Aberdeen in 1751. There he formed, with John Gregory, the Aberdeen Philosophical Society, which met fortnightly, often to discuss Hume. Reid published his Inquiry into the Human Mind on the Principles of Common Sense in 1764, and, in the same year, succeeded Adam Smith in the chair of moral philosophy at Old  in Glasgow. After 1780 he no longer lectured but devoted himself to his later works, Essays on the Intellectual Powers 1785 and Essays on the Active Powers 1788. He was highly influential in Scotland and on the Continent in the eighteenth century and, from time to time, in England and the United States thereafter. Reid thought that one of his major contributions was the refutation of Hume’s theory of impressions and ideas. Reid probably was convinced in his teens of the truth of Berkeley’s doctrine that what the mind is immediately aware of is always some idea, but his later study of Hume’s Treatise convinced him that, contrary to Berkeley, it was impossible to reconcile this doctrine, the theory of ideas, with common sense. Hume had rigorously developed the theory, Reid said, and drew forth the conclusions. These, Reid averred, were absurd. They included the denial of our knowledge of body and mind, and, even more strikingly, of our conceptions of these things. The reason Reid thought that Hume’s theory of ideas led to these conclusions was that for Hume, ideas were faded impressions of sense, hence, sensations. No sensation is like a quality of a material thing, let alone like the object that has the quality. Consider movement. Movement is a quality of an object wherein the object changes from one place to another, but the visual sensation that arises in us is not the change of place of an object, it is an activity of mind. No two things could, in fact, be more unalike. If what is before the mind is always some sensation, whether vivacious or faded, we should never obtain the conception of something other than a sensation. Hence, we could never even conceive of material objects and their qualities. Even worse, we could not conceive of our own minds, for they are not sensations either, and only sensations are immediately before the mind, according to the theory of ideas. Finally, and even more absurdly, we could not conceive of past sensations or anything that does not now exist. For all that is immediately before the mind is sensations that exist presently. Thus, we could not even conceive of qualities, bodies, minds, and things that do not now exist. But this is absurd, since it is obvious that we do think of all these things and even of things that have never existed. The solution, Reid suggested, is to abandon the theory of ideas and seek a better one. Many have thought Reid was unfair to Hume and misinterpreted him. Reid’s Inquiry was presented to Hume by Dr. Blair in manuscript form, however, and in reply Hume does not at all suggest that he has been misinterpreted or handled unfairly. Whatever the merits of Reid’s criticism of Hume, it was the study of the consequences of Hume’s philosophy that accounts for Reid’s central doctrine of the human faculties and their first principles. Faculties are innate powers, among them the powers of conception and conviction. Reid’s strategy in reply to Hume is to build a nativist theory of conception on the failure of Hume’s theory of ideas. Where the theory of ideas, the doctrine of impressions and ideas, fails to account for our conception of something, of qualities, bodies, minds, past things, nonexistent things, Reid hypothesizes that our conceptions originate from a faculty of the mind, i.e., from an innate power of conception. This line of argument reflects Reid’s respect for Hume, whom he calls the greatest metaphysician of the age, because Hume drew forth the consequences of a theory of conception, which we might call associationism, according to which all our conceptions result from associating sensations. Where the associationism of Hume failed, Reid hypothesized that conceptions arise from innate powers of conception that manifest themselves in accordance with original first principles of the mind. The resulting hypotheses were not treated as a priori necessities but as empirical hypotheses. Reid notes, therefore, that there are marks by which we can discern the operation of an innate first principle, which include the early appearance of the operation, its universality in mankind, and its irresistibility. The operations of the mind that yield our conceptions of qualities, bodies, and minds all bear these marks, Reid contends, and that warrants the conclusion that they manifest first principles. It should be noted that Reid conjectured that nature would be frugal in the implantation of innate powers, supplying us with no more than necessary to produce the conceptions we manifest. Reid is, consequently, a parsimonious empiricist in the development of his nativist psychology. Reid developed his theory of perception in great detail and his development led, surprisingly, to his articulation of non-Euclidean geometry. Indeed, while Kant was erroneously postulating the a priori necessity of Euclidean space, Reid was developing non-Euclidean geometry to account for the empirical features of visual space. Reid’s theory of perception is an example of his empiricism. In the Inquiry, he says that sensations, which are operations of the mind, and impressions on the organs of sense, which are material, produce our conceptions of primary and secondary qualities. Sensations produce our original conceptions of secondary qualities as the causes of those sensations. They are signs that suggest the existence of the qualities. A sensation of smell suggests the existence of a quality in the object that causes the sensation, though the character of the cause is otherwise unknown. Thus, our original conception of secondary qualities is a relative conception of some unknown cause of a sensation. Our conception of primary qualities differs not, as Locke suggested, because of some resemblance between the sensation and the quality for, as Berkeley noted, there is no resemblance between a sensation and quality, but because our original conceptions of primary qualities are clear and distinct. The sensation is a sign that suggests a definite conception of the primary quality, e.g. a definite conception of the movement of the object, rather than a mere conception of something, we know not what, that gives rise to the sensation. These conceptions of qualities signified by sensations result from the operations of principles of our natural constitution. These signs, which suggest the conception of qualities, also suggest a conception of some object that has them. This conception of the object is also relative, in that it is simply a conception of a subject of the qualities. In the case of physical qualities, the conception of the object is a conception of a material object. Though sensations, which are activities of the mind, suggest the existence of qualities, they are not the only signs of sense perception. Some impressions on the organs of sense, the latter being material, also give rise to conceptions of qualities, especially to our conception of visual figure, the seen shape of the object. But Reid can discern no sensation of shape. There are, of course, sensations of color, but he is convinced from the experience of those who have cataracts and see color but not shape that the sensations of color are insufficient to suggest our conceptions of visual figure. His detailed account of vision and especially of the seeing of visual figure leads him to one of his most brilliant moments. He asks what sort of data do we receive upon the eye and answers that the data must be received at the round surface of the eyeball and processed within. Thus, visual space is a projection in three dimensions of the information received on the round surface of the eye, and the geometry of this space is a non-Euclidean geometry of curved space. Reid goes on to derive the properties of the space quite correctly, e.g., in concluding that the angles of a triangle will sum to a figure greater than 180 degrees and thereby violate the parallels postulate. Thus Reid discovered that a non-Euclidean geometry was satisfiable and, indeed, insisted that it accurately described the space of vision not, however, the space of touch, which he thought was Euclidean. From the standpoint of his theory of perceptual signs, the example of visual figure helps to clarify his doctrine of the signs of perception. We do not perceive signs and infer what they signify. This inference, Reid was convinced by Hume, would lack the support of reasoning, and Reid concluded that reasoning was, in this case, superfluous. The information received on the surface of the eye produces our conceptions of visual figure immediately. Indeed, these signs pass unnoticed as they give rise to the conception of visual figure in the mind. The relation of sensory signs to the external things they signify originally is effected by a first principle of the mind without the use of reason. The first principles that yield our conceptions of qualities and objects yield convictions of the existence of these things at the same time. A question naturally arises as to the evidence of these convictions. First principles yield the convictions along with the conceptions, but do we have evidence of the existence of the qualities and objects we are convinced exist? We have the evidence of our senses, of our natural faculties, and that is all the evidence possible here. Reid’s point is that the convictions in questions resulting from the original principles of our faculties are immediately justified. Our faculties are, however, all fallible, so the justification that our original convictions possess may be refuted. We can now better understand Reid’s reply to Hume. To account for our convictions of the existence of body, we must abandon Hume’s theory of ideas, which cannot supply even the conception of body. We must discover both the original first principles that yield the conception and conviction of objects and their qualities, and first principles to account for our convictions of the past, of other thinking beings, and of morals. Just as there are first principles of perception that yield convictions of the existence of presently existing objects, so there are first principles of memory that yield the convictions of the existence of past things, principles of testimony that yield the convictions of the thoughts of others, and principles of morals that yield convictions of our obligations. Reid’s defense of a moral faculty alongside the faculties of perception and memory is striking. The moral faculty yields conceptions of the justice and injustice of an action in response to our conception of that action. Reid shrewdly notes that different people may conceive of the same action in different ways. I may conceive of giving some money as an action of gratitude, while you may consider it squandering money. How we conceive of an action depends on our moral education, but the response of our moral faculty to an action conceived in a specific way is original and the same in all who have the faculty. Hence differences in moral judgment are due, not to principles of the moral faculty, but to differences in how we conceive of our actions. This doctrine of a moral faculty again provides a counterpoint to the moral philosophy of Hume, for, according Reid, Thomas Reid, Thomas 785    785 to Reid, judgments of justice and injustice pertaining to all matters, including promises, contracts, and property, arise from our natural faculties and do not depend on anything artificial. Reid’s strategy for defending common sense is clear enough. He thinks that Hume showed that we cannot arrive at our convictions of external objects, of past events, of the thoughts of others, of morals, or, for that matter, of our own minds, from reasoning about impressions and ideas. Since those convictions are a fact, philosophy must account for them in the only way that remains, by the hypothesis of innate faculties that yield them. But do we have any evidence for these convictions? Evidence, Reid says, is the ground of belief, and our evidence is that of our faculties. Might our faculties deceive us? Reid answers that it is a first principle of our faculties that they are not fallacious. Why should we assume that our faculties are not fallacious? First, the belief is irresistible. However we wage war with first principles, the principles of common sense, they prevail in daily life. There we trust our faculties whether we choose to or not. Second, all philosophy depends on the assumption that our faculties are not fallacious. Here Reid employs an ad hominem argument against Hume, but one with philosophical force. Reid says that, in response to a total skeptic who decides to trust none of his faculties, he puts his hand over his mouth in silence. But Hume trusted reason and consciousness, and therefore is guilty of pragmatic inconsistency in calling the other faculties into doubt. They come from the same shop, Reid says, and he who calls one into doubt has no right to trust the others. All our faculties are fallible, and, therefore, we must, to avoid arbitrary favoritism, trust them all at the outset or trust none. The first principles of our faculties are trustworthy. They not only account for our convictions, but are the ground and evidence of those convictions. This nativism is the original engine of justification. Reid’s theory of original perceptions is supplemented by a theory of acquired perceptions, those which incorporate the effects of habit and association, such as the perception of a passing coach. He distinguishes acquired perceptions from effects of reasoning. The most important way our original perceptions must be supplemented is by general conceptions. These result from a process whereby our attention is directed to some individual quality, e.g., the whiteness of a piece of paper, which he calls abstraction, and a further process of generalizing from the individual quality to the general conception of the universal whiteness shared by many individuals. Reid is a sophisticated nominalist; he says that the only things that exist are individual, but he includes individual qualities as well as individual objects. The reason is that individual qualities obviously exist and are needed as the basis of generalization. To generalize from an individual we must have some conception of what it is like, and this conception cannot be general, on pain of circularity or regress, but must be a conception of an individual quality, e.g., the whiteness of this paper, which it uniquely possesses. Universals, though predicated of objects to articulate our knowledge, do not exist. We can think of universals, just as we can think of centaurs, but though they are the objects of thought and predicated of individuals that exist, they do not themselves exist. Generalization is not driven by ontology but by utility. It is we and not nature that sort things into kinds in ways that are useful to us. This leads to a division-of-labor theory of meaning because general conceptions are the meanings of general words. Thus, in those domains in which there are experts, in science or the law, we defer to the experts concerning the general conceptions that are the most useful in the area in question. Reid’s theory of the intellectual powers, summarized briefly above, is supplemented by his theory of our active powers, those that lead to actions. His theory of the active powers includes a theory of the principles of actions. These include animal principles that operate without understanding, but the most salient and philosophically important part of Reid’s theory of the active powers is his theory of the rational principles of action, which involve understanding and the will. These rational principles are those in which we have a conception of the action to be performed and will its performance. Action thus involves an act of will or volition, but volitions as Reid conceived of them are not the esoteric inventions of philosophy but, instead, the commonplace activities of deciding and resolving to act. Reid is a libertarian and maintains that our liberty or freedom refutes the principle of necessity or determinism. Freedom requires the power to will the action and also the power not to will it. The principle of necessity tells us that our action was necessitated and, therefore, that it was not in our power not to have willed as we did. It is not sufficient for freedom, as Hume suggested, that we act as we will. We must also have the Reid, Thomas Reid, Thomas 786    786 power to determine what we will. The reason is that willing is the means to the end of action, and he who lacks power over the means lacks power over the end. This doctrine of the active power over the determinations of our will is founded on the central principle of Reid’s theory of the active powers, the principle of agent causation. The doctrine of acts of the will or volitions does not lead to a regress, as critics allege, because my act of will is an exercise of the most basic kind of causality, the efficient causality of an agent. I am the efficient cause of my acts of will. My act of will need not be caused by an antecedent act of will because my act of will is the result of my exercise of my causal power. This fact also refutes an objection to the doctrine of liberty  that if my action is not necessitated, then it is fortuitous. My free actions are caused, not fortuitous, though they are not necessitated, because they are caused by me. How, one might inquire, do we know that we are free? The doubt that we are free is like other skeptical doubts, and receives a similar reply, namely, that the conviction of our freedom is a natural and original conviction arising from our faculties. It occurs prior to instruction and it is irresistible in practical life. Any person with two identical coins usable to pay for some item must be convinced that she can pay with the one or the other; and, unlike the ass of Buridan, she readily exercises her power to will the one or the other. The conviction of freedom is an original one, not the invention of philosophy, and it arises from the first principles of our natural faculties, which are trustworthy and not fallacious. The first principles of our faculties hang together like links in a chain, and one must either raise up the whole or the links prove useless. Together, they are the foundation of true philosophy, science, and practical life, and without them we shall lead ourselves into the coalpit of skepticism and despair. 

reimarus: G. philosopher, born in Hamburg and educated in philosophy at Jena. For most of his life he taught foreignl languages at a high school in Hamburg (“anything but Deutsche!”). The most important writings he published were a treatise on natural religion, Abhandlungen von den vornehmsten Wahrheiten der natürlichen Religion,  a textbook on semantics, which he pretentiously called “Vernunftlehre,”  and an interesting work on instincts in animals, “Allgemeine Betrachtungen über die Triebe der Tiere,” “which Strawson thought was about deer!” – Grice.  However, Reimarus is  best known for his Apologie oder Schutzschrift für die vernünftigen Verehrer Gottes.” In it, Reimarus reverses his stance on natural theology and openly advocates a deism in the British tradition. The controversy created by its publication had a profound impact on the further development of G. theology. Though Reimarus always remained basically a follower of Wolff, he is often quite critical of Wolffian rationalism in his discussion of semantics and philosophical psychology. 

Reinhold, Karl Leonhard 17431819, Austrian philosopher who was both a popularizer and a critic of Kant. He was the first occupant of the chair of critical philosophy established at the  of Jena in 1787. His Briefe über die Kantische Philosophie 1786/87 helped to popularize Kantianism. Reinhold also proclaimed the need for a more “scientific” presentation of the critical philosophy, in the form of a rigorously deductive system in which everything is derivable from a single first principle “the principle of consciousness”. He tried to satisfy this need with Elementarphilosophie “Elementary Philosophy” or “Philosophy of the Elements”, expounded in his Versuch einer neuen Theorie des menschlichen Vorstellungsvermögens “Attempt at a New Theory of the Human Faculty of Representation,” 1789, Beyträge zur Berichtigung bisheriger Missverständnisse der Philosophen I “Contributions to the Correction of the Prevailing Misunderstandings of Philosophers,” 1790, and Ueber das Fundament des philosophischen Wissens “On the Foundation of Philosophical Knowledge,” 1791. His criticism of the duality of Kant’s starting point and of the ad hoc character of his deductions contributed to the demand for a more coherent exposition of transcendental idealism, while his strategy for accomplishing this task stimulated others above all,
Fichte to seek an even more “fundamental” first principle for philosophy. Reinhold later became an enthusiastic adherent, first of Fichte’s Wissenschaftslehre and then of Bardili’s “rational realism,” before finally adopting a novel “linguistic” approach to philosophical problems. 

res: “No doubt the most important expression in the philosophical vocabulary – nobody knows what it means!” – Grice. reism, also called concretism, the theory that the basic entities are concrete objects. Reism differs from nominalism in that the problem of universals is not its only motivation and often not the principal motivation for the theory. Three types of reism can be distinguished. 1 Brentano held that every object is a concrete or individual thing. He said that substances, aggregates of substances, parts of substances, and individual properties of substances are the only things that exist. There is no such thing as the existence or being of an object; and there are no non-existent objects. One consequence of this doctrine is that the object of thought what the thought is about is always an individual object and not a proposition. For example, the thought that this paper is white is about this paper and not about the proposition that this paper is white. Meinong attacked Brentano’s concretism and argued that thoughts are about “objectives,” not objects. 2 Kotarbigski, who coined the term ‘reism’, holds as a basic principle that only concrete objects exist. Although things may be hard or soft, red or blue, there is no such thing as hardness, softness, redness, or blueness. Sentences that contain abstract words are either strictly meaningless or can be paraphrased into sentences that do not contain any abstract words. Kotarbinski is both a nominalist and a materialist. Brentano was a nominalist and a dualist. 3 Thomas Garrigue Masaryk’s concretism is quite different from the first two. For him, concretism is the theory that all of a person’s cognitive faculties participate in every instance of knowing: reason, senses, emotion, and will. 

relatum – Grice: “One should carefully distinguish between the prior ‘relatum’ and its formative, ‘relatIVUM.’” -- RELATUM -- referentially transparent. An occurrence of a singular term t in a sentence ‘. . . t . . .’ is referentially transparent or purely referential if and only if the truth-value of ‘. . . t . . .’ depends on whether the referent of t satisfies the open sentence ‘. . . x . . .’; the satisfaction of ‘. . . x . . .’ by the referent of t would guarantee the truth of ‘. . . t . . .’, and failure of this individual to satisfy ‘. . . x . . .’ would guarantee that ‘. . . t . . .’ was not true. ‘Boston is a city’ is true if and only if the referent of ‘Boston’ satisfies the open sentence ‘x is a city’, so the occurrence of ‘Boston’ is referentially transparent. But in ‘The expression “Boston” has six letters’, the length of the word within the quotes, not the features of the city Boston, determines the truth-value of the sentence, so the occurrence is not referentially transparent. According to a Fregean theory of meaning, the reference of any complex expression that is a meaningful unit is a function of the referents of its parts. Within this context, an occurrence of a referential term t in a meaningful expression ‘. . . t . . .’ is referentially transparent or purely referential if and only if t contributes its referent to the reference of ‘. . . t . . .’. The expression ‘the area around Boston’ refers to the particular area it does because of the referent of ‘Boston’ and the reference or extension of the function expressed by ‘the area around x’. An occurrence of a referential term t in a meaningful expression ‘. . . t . . .’ is referentially opaque if and only if it is not referentially transparent. Thus, if t has a referentially opaque occurrence in a sentence ‘. . . t . . .’, then the truth-value of ‘. . . t . . .’ depends on something reduction, phenomenological referentially transparent 780    780 other than whether the referent of t satisfies ‘. . . x . . .’. Although these definitions apply to occurrences of referential terms, the terms ‘referentially opaque’ and ‘referentially transparent’ are used primarily to classify linguistic contexts for terms as referentially opaque contexts. If t occurs purely referentially in S but not in CS, then C   is a referentially opaque context. But we must qualify this: C  is a referentially opaque context for that occurrence of t in S. It would not follow without further argument that C  is a referentially opaque context for other occurrences of terms in sentences that could be placed into C . Contexts of quotation, propositional attitude, and modality have been widely noted for their potential to produce referential opacity. Consider: 1 John believes that the number of planets is less than eight. 2 John believes that nine is less than eight. If 1 is true but 2 is not, then either ‘the number of planets’ or ‘nine’ has an occurrence that is not purely referential, because the sentences would differ in truth-value even though the expressions are co-referential. But within the sentences: 3 The number of planets is less than eight. 4 Nine is less than eight. the expressions appear to have purely referential occurrence. In 3 and 4, the truth-value of the sentence as a whole depends on whether the referent of ‘The number of planets’ and ‘Nine’ satisfies ‘x is less than eight’. Because the occurrences in 3 and 4 are purely referential but those in 1 and 2 are not, the context ‘John believes that  ’ is a referentially opaque context for the relevant occurrence of at least one of the two singular terms. Some argue that the occurrence of ‘nine’ in 2 is purely referential because the truth-value of the sentence as a whole depends on whether the referent, nine, satisfies the open sentence ‘John believes that x is less than eight’. Saying so requires that we make sense of the concept of satisfaction for such sentences belief sentences and others and that we show that the concept of satisfaction applies in this way in the case at hand sentence 2. There is controversy about whether these things can be done. In 1, on the other hand, the truth-value is not determined by whether nine the referent of ‘the number of planets’ satisfies the open sentence, so that occurrence is not purely referential. Modal contexts raise similar questions. 5 Necessarily, nine is odd. 6 Necessarily, the number of planets is odd. If 5 is true but 6 is not, then at least one of the expressions does not have a purely referential occurrence, even though both appear to be purely referential in the non-modal sentence that appears in the context ‘Necessarily, ———’. Thus the context is referentially opaque for the occurrence of at least one of these terms. On an alternative approach, genuinely singular terms always occur referentially, and ‘the number of planets’ is not a genuinely singular term. Russell’s theory of definite descriptions, e.g., provides an alternative semantic analysis for sentences involving definite descriptions. This would enable us to say that even simple sentences like 3 and 4 differ considerably in syntactic and semantic structure, so that the similarity that suggests the problem, the seemingly similar occurrences of co-referential terms, is merely apparent. “A formation out of referro,” -- a two-or-more-place property e.g., loves or between, or the extension of such a property. In set theory, a relation is any set of ordered pairs or triplets, etc., but these are reducible to pairs. For simplicity, the formal exposition here uses the language of set theory, although an intensional property-theoretic view is later assumed. The terms of a relation R are the members of the pairs constituting R, the items that R relates. The collection D of all first terms of pairs in R is the domain of R; any collection with D as a subcollection may also be so called. Similarly, the second terms of these pairs make up or are a subcollection of the range counterdomain or converse domain of R. One usually works within a set U such that R is a subset of the Cartesian product U$U the set of all ordered pairs on U. Relations can be: 1 reflexive or exhibit reflexivity: for all a, aRa. That is, a reflexive relation is one that, like identity, each thing bears to itself. Examples: a weighs as much as b; or the universal relation, i.e., the relation R such that for all a and b, aRb. 2 symmetrical or exhibit symmetry: for all a and b, aRb P bRa. In a symmetrical relation, the order of the terms is reversible. Examples: a is a sibling of b; a and b have a common divisor. Also symmetrical is the null relation, under which no object is related to anything. 3 transitive or exhibit transitivity: for all a, b, and c, aRb & bRc P aRc. Transitive relations carry across a middle term. Examples: a is less than b; a is an ancestor of b. Thus, if a is less than b and b is less than c, a is less than c: less than has carried across the middle term, b. 4 antisymmetrical: for all a and b, aRb & bRa P a % b. 5 trichotomous, connected, or total trichotomy: for all a and b, aRb 7 bRa 7 a % b. 6 asymmetrical: aRb & bRa holds for no a and b. 7 functional: for all a, b, and c, aRb & aRc P b % c. In a functional relation which may also be called a function, each first term uniquely determines a second term. R is non-reflexive if it is not reflexive, i.e., if the condition 1 fails for at least one object a. R is non-symmetric if 2 fails for at least one pair of objects a, b. Analogously for non-transitive. R is irreflexive aliorelative if 1 holds for no object a and intransitive if 3 holds for no objects a, b, and c. Thus understands is non-reflexive since some things do not understand themselves, but not irreflexive, since some things do; loves is nonsymmetric but not asymmetrical; and being a cousin of is non-transitive but not intransitive, as being mother of is. 13 define an equivalence relation e.g., the identity relation among numbers or the relation of being the same age as among people. A class of objects bearing an equivalence relation R to each other is an equivalence class under R. 1, 3, and 4 define a partial order; 3, 5, and 6 a linear order. Similar properties define other important classifications, such as lattice and Boolean algebra. The converse of a relation R is the set of all pairs b, a such that aRb; the comreism relation 788    788 plement of R is the set of all pairs a, b such that aRb i.e. aRb does not hold. A more complex example will show the power of a relational vocabulary. The ancestral of R is the set of all a, b such that either aRb or there are finitely many cI , c2, c3, . . . , cn such that aRcI and c1Rc2 and c2Rc3 and . . . and cnRb. Frege introduced the ancestral in his theory of number: the natural numbers are exactly those objects bearing the ancestral of the successor-of relation to zero. Equivalently, they are the intersection of all sets that contain zero and are closed under the successor relation. This is formalizable in second-order logic. Frege’s idea has many applications. E.g., assume a set U, relation R on U, and property F. An element a of U is hereditarily F with respect to R if a is F and any object b which bears the ancestral of R to a is also F. Hence F is here said to be a hereditary property, and the set a is hereditarily finite with respect to the membership relation if a is finite, its members are, as are the members of its members, etc. The hereditarily finite sets or the sets hereditarily of cardinality ‹ k for any inaccessible k are an important subuniverse of the universe of sets. Philosophical discussions of relations typically involve relations as special cases of properties or sets. Thus nominalists and Platonists disagree over the reality of relations, since they disagree about properties in general. Similarly, one important connection is to formal semantics, where relations are customarily taken as the denotations of relational predicates. Disputes about the notion of essence are also pertinent. One says that a bears an internal relation, R, to b provided a’s standing in R to b is an essential property of a; otherwise a bears an external relation to b. If the essentialaccidental distinction is accepted, then a thing’s essential properties will seem to include certain of its relations to other things, so that we must admit internal relations. Consider a point in space, which has no identity apart from its place in a certain system. Similarly for a number. Or consider my hand, which would perhaps not be the same object if it had not developed as part of my body. If it is true that I could not have had other parents  that possible persons similar to me but with distinct parents would not really be me  then I, too, am internally related to other things, namely my parents. Similar arguments would generate numerous internal relations for organisms, artifacts, and natural objects in general. Internal relations will also seem to exist among properties and relations themselves. Roundness is essentially a kind of shape, and the relation larger than is essentially the converse of the relation smaller than. In like usage, a relation between a and b is intrinsic if it depends just on how a and b are; extrinsic if they have it in virtue of their relation to other things. Thus, higher-than intrinsically relates the Alps to the Appalachians. That I prefer viewing the former to the latter establishes an extrinsic relation between the mountain ranges. Note that this distinction is obscure as is internal-external. One could argue that the Alps are higher than the Appalachians only in virtue of the relation of each to something further, such as space, light rays, or measuring rods. Another issue specific to the theory of relations is whether relations are real, given that properties do exist. That is, someone might reject nominalism only to the extent of admitting one-place properties. Although such doctrines have some historical importance in, e.g., Plato and Bradley, they have disappeared. Since relations are indispensable to modern logic and semantics, their inferiority to one-place properties can no longer be seriously entertained. Hence relations now have little independent significance in philosophy. 

Analysandum/analysans, definiens/definiendum, implicans/implicaturum

relational logic, the formal study of the properties of and operations on binary relations that was initiated by Peirce between 1870 and 2. Thus, in relational logic, one might examine the formal properties of special kinds of relations, such as transitive relations, or asymmetrical ones, or orderings of certain types. Or the focus might be on various operations, such as that of forming the converse or relative product. Formal deductive systems used in such studies are generally known as calculi of relations. 

relativum-absolutum distinction, the: “No, we don’t mean Whorft, less so Sapir!” – Grice. relativism, the denial that there are certain kinds of universal truths. There are two main types, cognitive and ethical. Cognitive relativism holds that there are no universal truths about the world: the world has no intrinsic characteristics, there are just different ways of interpreting it. The Grecian Sophist Protagoras, the first person on record to hold such a view, said, “Man is the measure of all things; of things that are that they are, and of things that are not that they are not.” Goodman, Putnam, and Rorty are contemporary philosophers who have held versions of relativism. Rorty says, e.g., that “ ‘objective truth’ is no more and no less than the best idea we currently have about how to explain what is going on.” Critics of cognitive relativism contend that it is self-referentially incoherent, since it presents its statements as universally true, rather than simply relatively so. Ethical relativism is the theory that there are no universally valid moral principles: all moral principles are valid relative to culture or individual choice. There are two subtypes: conventionalism, which holds that moral principles are valid relative to the conventions of a given culture or society; and subjectivism, which maintains that individual choices are what determine the validity of a moral principle. Its motto is, Morality lies in the eyes of the beholder. As Ernest Hemingway wrote, “So far, about morals, I know only that what is moral is what you feel good after and what is immoral is what you feel bad after.” Conventionalist ethical relativism consists of two theses: a diversity thesis, which specifies that what is considered morally right and wrong varies from society to society, so that there are no moral principles accepted by all societies; and a dependency thesis, which specifies that all moral principles derive their validity from cultural acceptance. From these two ideas relativists conclude that there are no universally valid moral principles applying everywhere and at all times. The first thesis, the diversity thesis, or what may simply be called cultural relativism, is anthropological; it registers the fact that moral rules differ from society to society. Although both ethical relativists and non-relativists typically accept cultural relativism, it is often confused with the normative thesis of ethical relativism. The opposite of ethical relativism is ethical objectivism, which asserts that although cultures may differ in their moral principles, some moral principles have universal validity. Even if, e.g., a culture does not recognize a duty to refrain from gratuitous harm, that principle is valid and the culture should adhere to it. There are two types of ethical objectivism, strong and weak. Strong objectivism, sometimes called absolutism, holds that there is one true moral system with specific moral rules. The ethics of ancient Israel in the Old Testament with its hundreds of laws exemplifies absolutism. Weak objectivism holds that there is a core morality, a determinate set of principles that are universally valid usually including prohibitions against killing the innocent, stealing, breaking of promises, and lying. But weak objectivism accepts an indeterminate area where relativism is legitimate, e.g., rules regarding sexual mores and regulations of property. Both types of objectivism recognize what might be called application relativism, the endeavor to apply moral rules where there is a conflict between rules or where rules can be applied in different ways. For example, the ancient Callactians ate their deceased parents but eschewed the impersonal practice of burying them as disrespectful, whereas contemporary society has the opposite attitudes about the care of dead relatives; but both practices exemplify the same principle of the respect for the dead. According to objectivism, cultures or forms of life can fail to exemplify an adequate moral community in at least three ways: 1 the people are insufficiently intelligent to put constitutive principles in order; 2 they are under considerable stress so that it becomes too burdensome to live by moral principles; and 3 a combination of 1 and 2. Ethical relativism is sometimes confused with ethical skepticism, the view that we cannot know whether there are any valid moral principles. Ethical nihilism holds that there are no valid moral principles. J. L. Mackie’s error theory is a version of this view. Mackie held that while we all believe some moral principles to be true, there are compelling arguments to the contrary. Ethical objectivism must be distinguished from moral realism, the view that valid moral principles are true, independently of human choice. Objectivism may be a form of ethical constructivism, typified by Rawls, whereby objective principles are simply those that impartial human beings would choose behind the veil of ignorance. That is, the principles are not truly independent of hypothetical human choices, but are constructs from those choices.   relativum-absolutum distinction, the: relativity, a term applied to Einstein’s theories of electrodynamics special relativity, 5 and gravitation general relativity, 6 because both hold that certain physical quantities, formerly considered objective, are actually “relative to” the state of motion of the observer. They are called “special” and “general” because, in special relativity, electrodynamical laws determine a restricted class of kinematical reference frames, the “inertial frames”; in general relativity, the very distinction between inertial frames and others becomes a relative distinction. Special relativity. Classical mechanics makes no distinction between uniform motion and rest: not velocity, but acceleration is physically detectable, and so different states of uniform motion are physically equivalent. But classical electrodynamics describes light as wave motion with a constant velocity through a medium, the “ether.” It follows that the measured velocity of light should depend on the motion of the observer relative to the medium. When interferometer experiments suggested that the velocity of light is independent of the motion of the source, H. A. Lorentz proposed that objects in motion contract in the direction of motion through the ether while their local time “dilates”, and that this effect masks the difference in the velocity of light. Einstein, however, associated the interferometry results with many other indications that the theoretical distinction between uniform motion and rest in the ether lacks empirical content. He therefore postulated that, in electrodynamics as in mechanics, all states of uniform motion are equivalent. To explain the apparent paradox that observers with different velocities can agree on the velocity of light, he criticized the idea of an “absolute” or frame-independent measure of simultaneity: simultaneity of distant events can only be established by some kind of signaling, but experiment suggested that light is the only signal with an invariant velocity, and observers in relative motion who determine simultaneity with light signals obtain different results. Furthermore, since objective measurement of time and length presupposes absolute simultaneity, observers in relative motion will also disagree on time and length. So Lorentz’s contraction and dilatation are not physical effects, but consequences of the relativity of simultaneity, length, and time, to the motion of the observer. But this relativity follows from the invariance of the laws of electrodynamics, and the invariant content of the theory is expressed geometrically in Minkowski spacetime. Logical empiricists took the theory as an illustration of how epistemological analysis of a concept time could eliminate empirically superfluous notions absolute simultaneity. General relativity. Special relativity made the velocity of light a limit for all causal processes and required revision of Newton’s theory of gravity as an instantaneous action at a distance. General relativity incorporates gravity into the geometry of space-time: instead of acting directly on one another, masses induce curvature in space-time. Thus the paths of falling bodies represent not forced deviations from the straight paths of a flat space-time, but “straightest” paths in a curved space-time. While space-time is “locally” Minkowskian, its global structure depends on mass-energy distribution. The insight behind this theory is the equivalence of gravitational and inertial mass: since a given gravitational field affects all bodies equally, weight is indistinguishable from the inertial force of acceleration; freefall motion is indistinguishable from inertial motion. This suggests that the Newtonian decomposition of free fall into inertial and accelerated components is arbitrary, and that the freefall path itself is the invariant basis for the structure of space-time. A philosophical motive for the general theory was to extend the relativity of motion. Einstein saw special relativity’s restricted class of equivalent reference frames as an “epistemological defect,” and he sought laws that would apply to any frame. His inspiration was Mach’s criticism of the Newtonian distinction between “absolute” rotation and rotation relative to observable bodies like the “fixed stars.” Einstein formulated Mach’s criticism as a fundamental principle: since only relative motions are observable, local inertial effects should be explained by the cosmic distribution of masses and by motion relative to them. Thus not only velocity and rest, but motion in general would be relative. Einstein hoped to effect this generalization by eliminating the distinction between inertial frames and freely falling frames. Because free fall remains a privileged state of motion, however, non-gravitational acceleration remains detectable, and absolute rotation remains distinct from relative rotation. Einstein also thought that relativity of motion would result from the general covariance coordinate-independence of his theory  i.e., that general equivalence of coordinate systems meant general equivalence of states of motion. It is now clear, however, that general covariance is a mathematical property of physical theories without direct implications about motion. So general relativity does not “generalize” the relativity of motion as Einstein intended. Its great accomplishments are the unification of gravity and geometry and the generalization of special relativity to space-times of arbitrary curvature, which has made possible the modern investigation of cosmological structure.

relevans: “Hardly in the vocabulary of Cartesio!” – Grice. relevance logic, any of a range of logics and philosophies of logic united by their insistence that the premises of a valid inference must be relevant to the conclusion. Standard, or classical, logic contains inferences that break this requirement, e.g., the spread law, that from a contradiction any proposition whatsoever follows. Relevance logic had its genesis in a system of strenge Implikation published by Wilhelm Ackermann in 6. Ackermann’s idea for rejecting irrelevance was taken up and developed by Alan Anderson and Nuel Belnap in a series of papers between 9 and Anderson’s death in 4. The first main summaries of these researches appeared under their names, and those of many collaborators, in Entailment: The Logic of Relevance and Necessity vol. 1, 5; vol. 2, 2. By the time of Anderson’s death, a substantial research effort into relevance logic was under way, and it has continued. Besides the rather vague unity of the idea of relevance between premises and conclusion, there is a technical criterion often used to mark out relevance logic, introduced by Belnap in 0, and applicable really only to propositional logics the main focus of concern to date: a necessary condition of relevance is that premises and conclusion should share a propositional variable. Early attention was focused on systems E of entailment and T of ticket entailment. Both are subsystems of C. I. Lewis’s system S4 of strict implication and of classical truth-functional logic i.e., consequences in E and T in ‘P’ are consequences in S4 in ‘ ’ and in classical logic in ‘/’. Besides rejection of the spread law, probably the most notorious inference that is rejected is disjunctive syllogism DS for extensional disjunction which is equivalent to detachment for material implication: A 7 B,ÝA , B. The reason is immediate, given acceptance of Simplification and Addition: Simplification takes us from A & ÝA to each conjunct, and Addition turns the first conjunct into A 7 B. Unless DS were rejected, the spread law would follow. Since the late 0s, attention has shifted to the system R of relevant implication, which adds permutation to E, to mingle systems which extend E and R by the mingle law A P A P A, and to contraction-free logics, which additionally reject contraction, in one form reading A P A P B P A P B. R minus contraction RW differs from linear logic, much studied recently in computer science, only by accepting the distribution of ‘&’ over ‘7’, which the latter rejects. Like linear logic, relevance logic contains both truth-functional and non-truth-functional connectives. Unlike linear logic, however, R, E, and T are undecidable unusual among propositional logics. This result was obtained only in 4. In the early 0s, relevance logics were given possible-worlds semantics by several authors working independently. They also have axiomatic, natural deduction, and sequent or consecution formulations. One technical result that has attracted attention has been the demonstration that, although relevance logics reject DS, they all accept Ackermann’s rule Gamma: that if A 7 B and ÝA are theses, so is B. A recent result occasioning much surprise was that relevant arithmetic consisting of Peano’s postulates on the base of quantified R does not admit Gamma.

reliabile, the, n. neuter. -- reliabilism, a type of theory in epistemology that holds that what qualifies a belief as knowledge or as epistemically justified is its *reliable* linkage to the truth. Philosophers usually motivate reliabilism with an analogy between a thermometer that reliably indicates the temperature and a belief that reliably indicates the truth. A belief qualifies as knowledge,  if there is a lawlike connection in nature that guarantees that the belief is true. A cousin of the nomic sufficiency account is the counterfactual approach, proposed by Dretske, Goldman, and Nozick. A typical formulation of this approach says that a belief qualifies relativity, general reliabilism 792    792 as knowledge if the belief is true and the cognizer has reasons for believing it that would not obtain unless it were true. For example, someone knows that the telephone is ringing if he believes this, it is true, and he has a specific auditory experience that would not occur unless the telephone were ringing. In a slightly different formulation, someone knows a proposition if he believes it, it is true, and if it were not true he would not believe it. In the example, if the telephone were not ringing, he would not believe that it is, because he would not have the same auditory experience. These accounts are guided by the idea that to know a proposition it is not sufficient that the belief be “accidentally” true. Rather, the belief, or its mode of acquisition, must “track,” “hook up with,” or “indicate” the truth. Unlike knowledge, justified belief need not guarantee or be “hooked up” with the truth, for a justified belief need not itself be true. Nonetheless, reliabilists insist that the concept of justified belief also has a connection with truth acquisition. According to the reliable process account, a belief’s justificational status depends on the psychological processes that produce or sustain it. Justified beliefs are produced by appropriate psychological processes, unjustified beliefs by inappropriate processes. For example, beliefs produced or preserved by perception, memory, introspection, and “good” reasoning are justified, whereas beliefs produced by hunch, wishful thinking, or “bad” reasoning are unjustified. Why are the first group of processes appropriate and the second inappropriate? The difference appears to lie in their reliability. Among the beliefs produced by perception, introspection, or “good” reasoning, a high proportion are true; but only a low proportion of beliefs produced by hunch, wishful thinking, or “bad” reasoning are true. Thus, what qualifies a belief as justified is its being the outcome of a sequence of reliable belief-forming processes. Reliabilism is a species of epistemological externalism, because it makes knowledge or justification depend on factors such as truth connections or truth ratios that are outside the cognizer’s mind and not necessarily accessible to him. Yet reliabilism typically emphasizes internal factors as well, e.g., the cognitive processes responsible for a belief. Process reliabilism is a form of naturalistic epistemology because it centers on cognitive operations and thereby paves the way for cognitive psychology to play a role in epistemology. Grice: “I expect that my co-conversationalist shall be realiable, as I assume he expects I will, too – or is it I assume he expects I *shall*?” Grice: “Covnersational reliability.”

renouvier: philosopher influenced by Kant and Comte, the latter natural, Comte being one of his teachers – “and brainwashing so endemic in academia it hurts! I’m lucky Hardie wasn’t worth my mimesis!” – Grice.  Renouvier rejected many of the views of both these philosophers, however, charting his own course. He emphasized the irreducible plurality and individuality of all things against the contemporary tendencies toward absolute idealism. Human individuality he associated with indeterminism and freedom. To the extent that agents are undetermined by other things and self-determining, they are unique individuals. Indeterminism also extends to the physical world and to knowledge. He rejected absolute certitude, but defended the universality of the laws of logic and mathematics. In politics and religion, he emphasized individual freedom and freedom of conscience. His emphasis on plurality, indeterminism, freedom, novelty, and process influenced James and, through James,  pragmatism. 

re-praesentatum: Grice plays with this as a philosophical semanticist, rather than a philosophical psychologist. But the re-praesentatum depends on the ‘praesentatum,’ which corresponds to Grice’s sub-perceptum (not the ‘conceptus’). cf. Grice on Peirce’s representamen (“You don’t want to go there,” – Grice to his tutees). It seems that in the one-off predicament, iconicy plays a role: the drawing of a skull to indicate danger, the drawing of an arrow at the fork of a road to indicate which way the emissor’s flowers, who were left behind, are supposed to take (Carruthers). Suppose Grice joins the Oxfordshire cricket club. He will represent Oxfordshire. He will do for Oxfordshire what Oxfordshire cannot do for herself. Similarly, by uttering “Smoke!,” the utterer means that there is fire somewhere. “Smoke!” is a communication-device if it does for smoke what smoke cannot do for itself, influence thoughts and behaviour. Or does it?! It MWheIGHT. But suppose that the fire is some distant from the addresse. And the utterer HAS LEARNED That there is fire in the distance. So he utters ‘Smoke!’ Where? Oh, you won’t see it. But I was told there is smoke on the outskirts. Thanks for warning me! rĕ-praesento , āvi, ātum, 1, v. a.  I.

res publica --: republicanism: cf. Cato -- Grice was a British subject and found classical republicanism false -- also known as civic humanism, a political outlook developed by Machiavelli in Renaissance Italy and by James Harrington in England, modified by eighteenth-century British and Continental writers and important for the thought of the  founding fathers. Drawing on Roman historians, Machiavelli argued that a state could hope for security from the blows of fortune only if its male citizens were devoted to its well-being. They should take turns ruling and being ruled, be always prepared to fight for the republic, and limit their private possessions. Such men would possess a wholly secular virtù appropriate to political beings. Corruption, in the form of excessive attachment to private interest, would then be the most serious threat to the republic. Harrington’s utopian Oceana 1656 portrayed England governed under such a system. Opposing the authoritarian views of Hobbes, it described a system in which the well-to-do male citizens would elect some of their number to govern for limited terms. Those governing would propose state policies; the others would vote on the acceptability of the proposals. Agriculture was the basis of economics, civil rights classical republicanism 145   145 but the size of estates was to be strictly controlled. Harringtonianism helped form the views of the political party opposing the dominance of the king and court. Montesquieu in France drew on classical sources in discussing the importance of civic virtue and devotion to the republic. All these views were well known to Jefferson, Adams, and other  colonial and revolutionary thinkers; and some contemporary communitarian critics of  culture return to classical republican ideas. 

stimulus/response distinction, the: Grice’s motto: “No stimulus, no response.” “The black box is meant to EXPLAIN (make plain) the link between the stimulus and the response – and no item in the black box should be postulated that it lacks this explanatory adequacy. “As Witters says, “No mental concept without the behaviour the mental concept is brought to explain.” Chomsky hated it. Grice changed it to ‘effect.’ Or not. “Stimulus and response,” Skinner's behavioral theory was largely set forth in his first book, Behavior of Organisms (1938).[9] Here, he gives a systematic description of the manner in which environmental variables control behavior. He distinguished two sorts of behavior which are controlled in different ways:  Respondent behaviors are elicited by stimuli, and may be modified through respondent conditioning, often called classical (or pavlovian) conditioning, in which a neutral stimulus is paired with an eliciting stimulus. Such behaviors may be measured by their latency or strength. Operant behaviors are 'emitted,' meaning that initially they are not induced by any particular stimulus. They are strengthened through operant conditioning (aka instrumental conditioning), in which the occurrence of a response yields a reinforcer. Such behaviors may be measured by their rate. Both of these sorts of behavior had already been studied experimentally, most notably: respondents, by Ivan Pavlov;[25] and operants, by Edward Thorndike.[26] Skinner's account differed in some ways from earlier ones,[27] and was one of the first accounts to bring them under one roof.

rerum natura: Latin, ‘the nature of things’, or ‘reality,’ to use the root of ‘res,’ cognate with ‘ratio,’ – (as ‘ding’ is connected with ‘denken,’ and ‘logos’ with ‘legein’ -- metaphysics. The phrase can also be used more narrowly to mean the nature of physical reality, and often it presupposes a naturalistic view of all reality. Lucretius’s epic poem “De rerum natura,” is an Epicurean physics, designed to underpin the Epicurean morality. Seneca told Lucrezio, “You could have looked for a catchier title if you want it a best-seller.”

responsabile, the responsabile: responsibility – cited by H. P. Grice in “The causal theory of perception” -- a condition that relates an agent to actions of, and consequences connected to, that agent, and is always necessary and sometimes sufficient for the appropriateness of certain kinds of appraisals of that agent. Responsibility has no single definition, but is several closely connected specific concepts. Role responsibility. Agents are identified by social roles that they occupy, say parent or professor. Typically duties are associated with such roles  to care for the needs of their children, to attend classes and publish research papers. A person in a social role is “responsible for” the execution of those duties. One who carries out such duties is “a responsible person” or “is behaving responsibly.” Causal responsibility. Events, including but not limited to human actions, cause other events. The cause is “responsible” for the effect. Causal responsibility does not imply consciousness; objects and natural phenomena may have causal responsibility. Liability responsibility. Practices of praise and blame include constraints on the mental stance that an agent must have toward an action or a consequence of action, in order for praise or blame to be appropriate. To meet such constraints is to meet a fundamental necessary condition for liability for praise or blame  hence the expression ‘liability responsibility’. These constraints include such factors as intention, knowledge, recklessness toward consequences, absence of mistake, accident, inevitability of choice. An agent with the capability for liability responsibility may lack it on some occasion  when mistaken, for example. Capacity responsibility. Practices of praise and blame assume a level of intellectual and emotional capability. The severely mentally disadvantaged or the very young, for example, do not have the capacity to meet the conditions for liability responsibility. They are not “responsible” in that they lack capacity responsibility. Both morality and law embody and respect these distinctions, though law institutionalizes and formalizes them. Final or “bottom-line” assignment of responsibility equivalent to indeed deserving praise or blame standardly requires each of the latter three specific kinds of responsibility. The first kind supplies some normative standards for praise or blame. 

resultus: or resultance, a relation according to which one property the resultant property, sometimes called the consequential property is possessed by some object or event in virtue of and hence as a result of that object or event possessing some other property or set of properties. The idea is that properties of things can be ordered into connected levels, some being more basic than and giving rise to others, the latter resulting from the former. For instance, a figure possesses the property of being a triangle in virtue of its possessing a collection of properties, including being a plane figure, having three sides, and so on; the former resulting from the latter. An object is brittle has the property of being brittle in virtue of having a certain molecular structure. It is often claimed that moral properties like rightness and goodness are resultant properties: an action is right in virtue of its possessing other properties. These examples make it clear that the nature of the necessary connection holding between a resultant property and those base properties that ground it may differ from case to case. In the geometrical example, the very concept of being a triangle grounds the resultance relation in question, and while brittleness is nomologically related to the base properties from which it results, in the moral case, the resultance relation is arguably neither conceptual nor causal. 

cornwall – “He hardly spoke English – and Grosseteste hardly spoke Cornish – yet they became best friends at Oxford – Fishacre helped. “But they communicated mainly in the lingua franca, that is Roman!” -- Rrichard Rufus, also called Richard of Cornwall English philosopher who wrote some of the earliest commentaries on Aristotle in the Latin West. Cornwall’s commentaries are not cursory summaries; they include sustained philosophical discussions. “Cornwall,” as he was called (cf. Grice’s “Shropshire,” – all I remember about him is that his name was that of a shire”) was a master of arts at Paris, where he studied with Hales. And they would joke, “I was called after a shire, but you after a town, ain’t that unfair?” – Cornwall is also deeply influenced by Grosseteste – “he of the great head” – or “balls” (testis, testiculus). Cornwall leaves Paris and joins the Franciscan order. He was ordained in England. In 1256, he became regent master of the Franciscan studium at Oxford (“of course,” Grice); according to Bacon, Cornwall is the most influential philosopher  at Oxford In addition to his Aristotle commentaries, Cornwall writes two commentaries on Peter Lombard’s Sentences. In the first of these he borrows  freely from Grosseteste, Hales, and Fishacre (“if you’ve heard of him” – Grice). The second commentary is a critical condensation of the lectures of Fidanza, presented in Paris. Cornwall is a  proponent of the theory of impetus. His views on projectile motion are cited by  Meyronnes. Cornwall also advocates other arguments first presented by Philoponus. Against the eternity of the world, he argued that past time is necessarily finite, since it has been traversed, and, on top, the world is hardly eternal, since “if the world has no beginning, no more time transpires before tomorrow than it transpires before today – but it does so transpire.” Cornwall also argues that if the world had not been created ex nihilo, the first cause would be mutable. Grosseteste cited one of Cornwalls arguments against the eternity of the world in his notes on Aristotle’s Physics. Cornwall denies the validity of Anselm’s ontological argument, but, anticipating Duns Scotus, Cornwall argues that the existence of an independent being could be inferred from its possibility. Like Duns Scotus, Cornwall employs the formal distinction as an explanatory tool; in presenting his own views, Duns Scotus cites Cornwall’s’s definition of the “formal distinction” versus the “material distinction.” Richard states his philosophical views briefly, even cryptically; his Latin prose style is sometimes eccentric (even Griceian), characterized by rather abrupt extemporaneous interjections in which he apparently means to addresses this or that question to God, to himself, or to his intended recipient. Cornwall is hesitant about the value of systematic theology for the theologian, deferring to biblical exposition as the primary forum for theological discussion. In systematic theology, he emphasized Aristotelian semanticsc. He was a well-known semanticist. Some scholars (Kneale, Grice, and Speranza included) believe Cornwall is the famous logician known as the “Magister Abstractionum.” Though Cornwall borrowed freely from his contemporaries, he was a profoundly original philosopher. 

ricoeur: hermeneuticist and phenomenologist who has been a professor at several  universities as well as the  of Naples, Yale , and the  of Chicago. He has received major prizes from France, G.y, and Italy. He is the author of twenty-some volumes tr. in a variety of languages. Among his best-known books are Freedom and Nature: The Voluntary and the Involuntary; Freud and Philosophy: An Essay of Interpretation; The Conflict of Interpretations: Essay in Hermeneutics; The Role of the Metaphor: Multi-Disciplinary Studies of the Creation of Meaning in Language, Time and Narrative; and Oneself as Another. His early studies with the  existentialist Marcel resulted in a book-length study of Marcel’s work and later a series of published dialogues with him. Ricoeur’s philosophical enterprise is colored by a continuing tension between faith and reason. His long-standing commitments to both the significance of the individual and the Christian faith are reflected in his hermeneutical voyage, his commitment to the Esprit movement, and his interest in the writings of Emmanuel Mounier. This latter point is also seen in his claim of the inseparability of action and discourse in our quest for meaning. In our comprehension of both history and fiction one must turn to the text to understand its plot as guideline if we are to comprehend experience of any reflective sort. In the end there are no metaphysical or epistemological grounds by which meaning can be verified, and yet our nature is such that possibility must be present before us. Ricoeur attempts his explanation through a hermeneutic phenomenology. The very hermeneutics of existence that follows is itself limited by reason’s questioning of experience and its attempts to transcend the limit through the language of symbols and metaphors. Freedom and meaning come to be realized in the actualization of an ethics that arises out of the very act of existing and thus transcends the mere natural voluntary distinction of a formal ethic. It is clear from his later work that he rejects any form of foundationalism including phenomenology as well as nihilism and easy skepticism. Through a sort of interdependent dialectic that goes beyond the more mechanical models of Hegelianism or Marxism, the self understands itself and is understood by the other in terms of its suffering and its moral actions.  Refs.: J. O. Urmson, “La pragmatique,” H. P. Grice, “The conflict of interpretations between me and Ricoeur, and vice versa.”

directus -- right: an advantageous position conferred on some possessor by law, morals, rule, or other norm. There is no agreement on the way in which a ‘right’ is an advantage. Will theories hold that rights favor the will of the possessor over the conflicting will of some other party; interest theories maintain that rights serve to protect or promote the interests of the right-holder. Hohfeld identified four legal advantages: liberties, claims, powers, and immunitiesThe concept of a right arose in Roman jurisprudence and was extended to ethics via natural law theory. Just as positive law, the law posited by human lawmakers, confers legal rights, so the natural law confers natural rights. Rights are classified by their specific sources in different sorts of rules. Legal rights are advantageous positions under the law of a society. Other species of institutional rights are conferred by the rules of private organizations, of the moral code of a society, or even of some game. Those who identify natural law with the moral law often identify natural rights with moral rights, but some limit natural rights to our most fundamental rights and contrast them with ordinary moral rights. Others deny that moral rights are natural because they believe that they are conferred by the mores or positive morality of one’s society. One always possesses any specific right by virtue of possessing some status. Thus, rights are also classified by status. Civil rights are those one possesses as a citizen; human rights are possessed by virtue of being human. Presumably women’s rights, children’s rights, patients’ rights, and the rights of blacks as such are analogous. Human rights play very much the same role in ethics once played by natural rights. This is partly because ontological doubts about the existence of God undermine the acceptance of any natural law taken to consist in divine commands, and epistemological doubts about self-evident moral truths lead many to reject any natural law conceived of as the dictates of reason. Although the Thomistic view that natural rights are grounded on the nature of man is often advocated, most moral philosophers reject its teleological conception of human nature defined by essential human purposes. It seems simpler to appeal instead to fundamental rights that must be universal among human beings because they are possessed merely by virtue of one’s status as a human being. Human rights are still thought of as natural in the very broad sense of existing independently of any human action or institution. This explains how they can be used as an independent standard in terms of which to criticize the laws and policies of governments and other organizations. Since human rights are classified by status rather than source, there is another species of human rights that are institutional rather than natural. These are the human rights that have been incorporated into legal systems by international agreements such as the European Convention on Human Rights. It is sometimes said that while natural rights were conceived as purely negative rights, such as the right not to be arbitrarily imprisoned, human rights are conceived more broadly to include positive social and economic rights, such as the right to social security or to an adequate standard of living. But this is surely not true by definition. Traditional natural law theorists such as Grotius and Locke spoke of natural rights as powers and associated them with liberties, rather than with claims against interference. And while modern declarations of human rights typically include social and economic rights, they assume that these are rights in the same sense that traditional political rights are. Rights are often classified by their formal properties. For example, the right not to be battered is a negative right because it imposes a negative duty not to batter, while the creditor’s right to be repaid is a positive right because it imposes a positive duty to repay. The right to be repaid is also a passive right because its content is properly formulated in the passive voice, while the right to defend oneself is an active right because its content is best stated in the active voice. Again, a right in rem is a right that holds against all second parties; a right in personam is a right that holds against one or a few others. This is not quite Hart’s distinction between general and special rights, rights of everyone against everyone, such as the right to free speech, and rights arising from special relations, such as that between creditor and debtor or husband and wife. Rights are conceptually contrasted with duties because rights are advantages while duties are disadvantages. Still, many jurists and philosophers have held that rights and duties are logical correlatives. This does seem to be true of claim rights; thus, the creditor’s right to be repaid implies the debtor’s duty to repay and vice versa. But the logical correlative of a liberty right, such as one’s right to park in front of one’s house, is the absence of any duty for one not to do so. This contrast is indicated by D. D. Raphael’s distinction between rights of recipience and rights of action. Sometimes to say that one has a right to do something is to say merely that it is not wrong for one to act in this way. This has been called the weak sense of ‘a right’. More often to assert that one has a right to do something does not imply that exercising this right is right. Thus, I might have a right to refuse to do a favor for a friend even though it would be wrong for me to do so. Finally, many philosophers distinguish between absolute and prima facie rights. An absolute right always holds, i.e., disadvantages some second party, within its scope; a prima facie right is one that holds unless the ground of the right is outweighed by some stronger contrary reason. Refs. H. P. Grice, “On the conceptual priority of the moral right over the legal right, and vice versa.”

rigorism, the view that morality consists in that single set of simple or unqualified moral rules, discoverable by reason, which applies to all human beings at all times. It is often said that Kant’s doctrine of the categorical imperative is rigoristic. Two main objections to rigorism are 1 some moral rules do not apply universally  e.g., ‘Promises should be kept’ applies only where there is an institution of promising; and 2 some rules that could be universally kept are absurd  e.g., that everyone should stand on one leg while the sun rises. Recent interpreters of Kant defend him against these objections by arguing, e.g., that the “rules” he had in mind are general guidelines for living well, which are in fact universal and practically relevant, or that he was not a rigorist at all, seeing moral worth as issuing primarily from the agent’s character rather than adherence to rules.

ring of Gyges, a ring that gives its wearer invisibility, discussed in Plato’s Republic II, 359b 360d. Glaucon tells the story of a man who discovered the ring and used it to usurp the throne to defend the claim that those who behave justly do so only because they lack the power to act unjustly. If they could avoid paying the penalty of injustice, Glaucon argues, everyone would be unjust.

roscelin de Compiègne: He made fun of Abelard having been ‘castrated’ for his philosophical dogmas on the universals. -- philosopher and logician who became embroiled in theological controversy when he applied his logical teachings to the doctrine of the Trinity. Since almost nothing survives of his written work, we must rely on hostile accounts of his views by Anselm of Canterbury and Peter Abelard, both of whom openly opposed his positions. Perhaps the most notorious view Roscelin is said to have held is that universals are merely the puffs of air produced when a word is pronounced. On this point he opposed views current among many theologians that a universal has an existence independent of language, and somehow is what many different particulars are. Roscelin’s aversion to any proposal that different things can be some one thing is probably what led him in his thinking about the three persons of God to a position that sounded suspiciously like the heresy of tritheism. Roscelin also evidently held that the qualities of things are not entities distinct from the subjects that possess them. This indicates that Roscelin probably denied that terms in the Aristotelian categories other than substance signified anything distinct from substances. Abelard, the foremost logician of the twelfth century, studied under Roscelin around 1095 and was undoubtedly influenced by him on the question of universals. Roscelin’s view that universals are linguistic entities remained an important option in medieval thought. Otherwise his positions do not appear to have had much currency in the ensuing decades.

rosmini: important Italian philosopher, Catholic priest, counselor to Pope Pius IX, and supporter of the supremacy of the church over civil government Neo-Guelphism. Rosmini had two major concerns: the objectivity of human knowledge and the synthesis of philosophical thought within the tradition of Catholic thought. In his Nuovo saggio sull’origine delle idee “New Essay on the Origin of Ideas,” 1830, he identifies the universal a priori intuitive component of all human knowledge with the idea of being that gives us the notion of a possible or ideal being. Everything in the world is known by intellectual perception, which is the synthesis of sensation and the idea of being. Except for the idea of being, which is directly given by God, all ideas derive from abstraction. The objectivity of human knowledge rests on its universal origin in the idea of being. The harmony between philosophy and religion comes from the fact that all human knowledge is the result of divine revelation. Rosmini’s thought was influenced by Augustine and Aquinas, and stimulated by the attempt to find a solution to the contrasting needs of rationalism and empiricism.

rousseau: philosopher, best known for his theories on social freedom and societal rights, education, and religion. Born in Geneva, he was largely self-educated and moved to France as a teenager. Throughout much of his life he moved between Paris and the provinces with several trips abroad including a Scottish stay with Hume and a return visit to Geneva, where he reconverted to Protestantism from his earlier conversion to Catholicism. For a time he was a friend of Diderot and other philosophes and was asked to contribute articles on music for the Encyclopedia. Rousseau’s work can be seen from at least three perspectives. As social contract theorist, he attempts to construct a hypothetical state of nature to explain the current human situation. This evolves a form of philosophical anthropology that gives us both a theory of human nature and a series of pragmatic claims concerning social organization. As a social commentator, he speaks of both practical and ideal forms of education and social organization. As a moralist, he continually attempts to unite the individual and the citizen through some form of universal political action or consent. In Discourse on the Origin and Foundation of Inequality Among Mankind 1755, Rousseau presents us with an almost idyllic view of humanity. In nature humans are first seen as little more than animals except for their special species sympathy. Later, through an explanation of the development of reason and language, he is able to suggest how humans, while retaining this sympathy, can, by distancing themselves from nature, understand their individual selves. This leads to natural community and the closest thing to what Rousseau considers humanity’s perfect moment. Private property quickly follows on the division of labor, and humans find themselves alienated from each other by the class divisions engendered by private property. Thus man, who was born in freedom, now finds himself in chains. The Social Contract or Principles of Political Right 1762 has a more ambitious goal. With an account of the practical role of the legislator and the introduction of the concept of the general will, Rousseau attempts to give us a foundation for good government by presenting a solution to the conflicts between the particular and the universal, the individual and the citizen, and the actual and the moral. Individuals, freely agreeing to a social pact and giving up their rights to the community, are assured of the liberties and equality of political citizenship found in the contract. It is only through being a citizen that the individual can fully realize his freedom and exercise his moral rights and duties. While the individual is naturally good, he must always guard against being dominated or dominating. Rousseau finds a solution to the problems of individual freedoms and interests in a superior form of moral/political action that he calls the general will. The individual as citizen substitutes “I must” for “I will,” which is also an “I shall” when it expresses assent to the general will. The general will is a universal force or statement and thus is more noble than any particular will. In willing his own interest, the citizen is at the same time willing what is communally good. The particular and the universal are united. The individual human participant realizes himself in realizing the good of all. As a practical political commentator Rousseau knew that the universal and the particular do not always coincide. For this he introduced the idea of the legislator, which allows the individual citizen to realize his fulfillment as social being and to exercise his individual rights through universal consent. In moments of difference between the majority will and the general will the legislator will instill the correct moral/political understanding. This will be represented in the laws. While sovereignty rests with the citizens, Rousseau does not require that political action be direct. Although all government should be democratic, various forms of government from representative democracy preferable in small societies to strong monarchies preferable in large nation-states may be acceptable. To shore up the unity and stability of individual societies, Rousseau suggests a sort of civic religion to which all citizens subscribe and in which all members participate. His earlier writings on education and his later practical treatises on the governments of Poland and Corsica reflect related concerns with natural and moral development and with historical and geographical considerations.

rule of law, the largely formal or procedural properties of a well-ordered legal system. Commonly, these properties are thought to include: a prohibition of arbitrary power the lawgiver is also subject to the laws; laws that are general, prospective, clear, and consistent capable of guiding conduct; and tribunals courts that are reasonably accessible and fairly structured to hear and determine legal claims. Contemporary discussions of the rule of law focus on two major questions: 1 to what extent is conformity to the rule of law essential to the very idea of a legal system; and 2 what is the connection between the rule of law and the substantive moral value of a legal system? 

Russell: “not really a philosopher,” as Grice puts it, by either education or practice, he was born of Celtic Highland stock into an aristocratic family in Wales (then part of England), Russell always divided his interests between politics, philosophy, and the ladies (he married six times). Orphaned at four, he was brought up by his grandmother, who educated him at home with the help of “rather dull” tutors. He studied mathematics at Cambridge and then, as his grandmother says, ‘out of the blue,’ he turned to philosophy. At home he had absorbed J. S. Mill’s liberalism, but not his empiricism. At Cambridge he came under the influence of neo-Hegelianism, especially the idealism of McTaggart, Ward his tutor, and Bradley. His earliest logical views were influenced most by Bradley, especially Bradley’s rejection of psychologism. But, like Ward and McTaggart, he rejected Bradley’s metaphysical monism in favor of pluralism or monadism. Even as an idealist, he held that scientific knowledge was the best available and that philosophy should be built around it. Through many subsequent changes, this belief about science, his pluralism, and his anti-psychologism remained constant. In 5, he conceived the idea of an idealist encyclopedia of the sciences to be developed by the use of transcendental arguments to establish the conditions under which the special sciences are possible. Russell’s first philosophical book, An Essay on the Foundations of Geometry 7, was part of this project, as were other mostly unfinished and unpublished pieces on physics and arithmetic written at this time see his Collected Papers, vols. 12. Russell claimed, in contrast to Kant, to use transcendental arguments in a purely logical way compatible with his anti-psychologism. In this case, however, it should be both possible and preferable to replace them by purely deductive arguments. Another problem arose in connection with asymmetrical relations, which led to contradictions if treated as internal relations, but which were essential for any treatment of mathematics. Russell resolved both problems in 8 by abandoning idealism including internal relations and his Kantian methodology. He called this the one real revolution in his philosophy. With his Cambridge contemporary Moore, he adopted an extreme Platonic realism, fully stated in The Principles of Mathematics 3 though anticipated in A Critical Exposition of the Philosophy of Leibniz 0. Russell’s work on the sciences was by then concentrated on pure mathematics, but the new philosophy yielded little progress until, in 0, he discovered Peano’s symbolic logic, which offered hope that pure mathematics could be treated without Kantian intuitions or transcendental arguments. On this basis Russell propounded logicism, the claim that the whole of pure mathematics could be derived deductively from logical principles, a position he came to independently of Frege, who held a similar but more restricted view but whose work Russell discovered only later. Logicism was announced in The Principles of Mathematics; its development occupied Russell, in collaboration with Whitehead, for the next ten years. Their results were published in Principia Mathematica 013, 3 vols., in which detailed derivations were given for Cantor’s set theory, finite and transfinite arithmetic, and elementary parts of measure theory. As a demonstration of Russell’s logicism, Principia depends upon much prior arithmetization of mathematics, e.g. of analysis, which is not explicitly treated. Even with these allowances much is still left out: e.g., abstract algebra and statistics. Russell’s unpublished papers Papers, vols. 45, however, contain logical innovations not included in Principia, e.g., anticipations of Church’s lambda-calculus. On Russell’s extreme realism, everything that can be referred to is a term that has being though not necessarily existence. The combination of terms by means of a relation results in a complex term, which is a proposition. Terms are neither linguistic nor psychological. The first task of philosophy is the theoretical analysis of propositions into their constituents. The propositions of logic are unique in that they remain true when any of their terms apart from logical constants are replaced by any other terms. In 1 Russell discovered that this position fell prey to self-referential paradoxes. For example, if the combination of any number of terms is a new term, the combination of all terms is a term distinct from any term. The most famous such paradox is called Russell’s paradox. Russell’s solution was the theory of types, which banned self-reference by stratifying terms and expressions into complex hierarchies of disjoint subclasses. The expression ‘all terms’, e.g., is then meaningless unless restricted to terms of specified types, and the combination of terms of a given type is a term of different type. A simple version of the theory appeared in Principles of Mathematics appendix A, but did not eliminate all the paradoxes. Russell developed a more elaborate version that did, in “Mathematical Logic as Based on the Theory of Types” 8 and in Principia. From 3 to 8 Russell sought to preserve his earlier account of logic by finding other ways to avoid the paradoxes  including a well-developed substitutional theory of classes and relations posthumously published in Essays in Analysis, 4, and Papers, vol. 5. Other costs of type theory for Russell’s logicism included the vastly increased complexity of the resulting sysRussell, Bertrand Arthur William Russell, Bertrand Arthur William 802    802 tem and the admission of the problematic axiom of reducibility. Two other difficulties with Russell’s extreme realism had important consequences: 1 ‘I met Quine’ and ‘I met a man’ are different propositions, even when Quine is the man I met. In the Principles, the first proposition contains a man, while the second contains a denoting concept that denotes the man. Denoting concepts are like Fregean senses; they are meanings and have denotations. When one occurs in a proposition the proposition is not about the concept but its denotation. This theory requires that there be some way in which a denoting concept, rather than its denotation, can be denoted. After much effort, Russell concluded in “On Denoting” 5 that this was impossible and eliminated denoting concepts as intermediaries between denoting phrases and their denotations by means of his theory of descriptions. Using firstorder predicate logic, Russell showed in a broad, though not comprehensive range of cases how denoting phrases could be eliminated in favor of predicates and quantified variables, for which logically proper names could be substituted. These were names of objects of acquaintance  represented in ordinary language by ‘this’ and ‘that’. Most names, he thought, were disguised definite descriptions. Similar techniques were applied elsewhere to other kinds of expression e.g. class names resulting in the more general theory of incomplete symbols. One important consequence of this was that the ontological commitments of a theory could be reduced by reformulating the theory to remove expressions that apparently denoted problematic entities. 2 The theory of incomplete symbols also helped solve extreme realism’s epistemic problems, namely how to account for knowledge of terms that do not exist, and for the distinction between true and false propositions. First, the theory explained how knowledge of a wide range of items could be achieved by knowledge by acquaintance of a much narrower range. Second, propositional expressions were treated as incomplete symbols and eliminated in favor of their constituents and a propositional attitude by Russell’s multiple relation theory of judgment. These innovations marked the end of Russell’s extreme realism, though he remained a Platonist in that he included universals among the objects of acquaintance. Russell referred to all his philosophy after 8 as logical atomism, indicating thereby that certain categories of items were taken as basic and items in other categories were constructed from them by rigorous logical means. It depends therefore upon reduction, which became a key concept in early analytic philosophy. Logical atomism changed as Russell’s logic developed and as more philosophical consequences were drawn from its application, but the label is now most often applied to the modified realism Russell held from 5 to 9. Logic was central to Russell’s philosophy from 0 onward, and much of his fertility and importance as a philosopher came from his application of the new logic to old problems. In 0 Russell became a lecturer at Cambridge. There his interests turned to epistemology. In writing a popular book, Problems of Philosophy 2, he first came to appreciate the work of the British empiricists, especially Hume and Berkeley. He held that empirical knowledge is based on direct acquaintance with sense-data, and that matter itself, of which we have only knowledge by description, is postulated as the best explanation of sense-data. He soon became dissatisfied with this idea and proposed instead that matter be logically constructed out of sensedata and unsensed sensibilia, thereby obviating dubious inferences to material objects as the causes of sensations. This proposal was inspired by the successful constructions of mathematical concepts in Principia. He planned a large work, “Theory of Knowledge,” which was to use the multiple relation theory to extend his account from acquaintance to belief and inference Papers, vol. 7. However, the project was abandoned as incomplete in the face of Vitters’s attacks on the multiple relation theory, and Russell published only those portions dealing with acquaintance. The construction of matter, however, went ahead, at least in outline, in Our Knowledge of the External World 4, though the only detailed constructions were undertaken later by Carnap. On Russell’s account, material objects are those series of sensibilia that obey the laws of physics. Sensibilia of which a mind is aware sense-data provide the experiential basis for that mind’s knowledge of the physical world. This theory is similar, though not identical, to phenomenalism. Russell saw the theory as an application of Ockham’s razor, by which postulated entities were replaced by logical constructions. He devoted much time to understanding modern physics, including relativity and quantum theory, and in The Analysis of Matter 7 he incorporated the fundamental ideas of those theories into his construction of the physical world. In this book he abandoned sensibilia as fundamental constituents of the world in favor Russell, Bertrand Arthur William Russell, Bertrand Arthur William 803    803 of events, which were “neutral” because intrinsically neither physical nor mental. In 6 Russell was dismissed from Cambridge on political grounds and from that time on had to earn his living by writing and public lecturing. His popular lectures, “The Philosophy of Logical Atomism” 8, were a result of this. These lectures form an interim work, looking back on the logical achievements of 510 and emphasizing their importance for philosophy, while taking stock of the problems raised by Vitters’s criticisms of the multiple relation theory. In 9 Russell’s philosophy of mind underwent substantial changes, partly in response to those criticisms. The changes appeared in “On Propositions: What They Are and How They Mean” 9 and The Analysis of Mind 1, where the influence of contemporary trends in psychology, especially behaviorism, is evident. Russell gave up the view that minds are among the fundamental constituents of the world, and adopted neutral monism, already advocated by Mach, James, and the  New Realists. On Russell’s neutral monism, a mind is constituted by a set of events related by subjective temporal relations simultaneity, successiveness and by certain special “mnemic” causal laws. In this way he was able to explain the apparent fact that “Hume’s inability to perceive himself was not peculiar.” In place of the multiple relation theory Russell identified the contents of beliefs with images “imagepropositions” and words “word-propositions”, understood as certain sorts of events, and analyzed truth qua correspondence in terms of resemblance and causal relations. From 8 to 4 Russell lived in the United States, where he wrote An Inquiry into Meaning and Truth 0 and his popular A History of Western Philosophy 5. His philosophical attention turned from metaphysics to epistemology and he continued to work in this field after he returned in 4 to Cambridge, where he completed his last major philosophical work, Human Knowledge: Its Scope and Limits 8. The framework of Russell’s early epistemology consisted of an analysis of knowledge in terms of justified true belief though it has been suggested that he unintentionally anticipated Edmund Gettier’s objection to this analysis, and an analysis of epistemic justification that combined fallibilism with a weak empiricism and with a foundationalism that made room for coherence. This framework was retained in An Inquiry and Human Knowledge, but there were two sorts of changes that attenuated the foundationalist and empiricist elements and accentuated the fallibilist element. First, the scope of human knowledge was reduced. Russell had already replaced his earlier Moorean consequentialism about values with subjectivism. Contrast “The Elements of Ethics,” 0, with, e.g., Religion and Science, 5, or Human Society in Ethics and Politics, 4. Consequently, what had been construed as self-evident judgments of intrinsic value came to be regarded as non-cognitive expressions of desire. In addition, Russell now reversed his earlier belief that deductive inference can yield new knowledge. Second, the degree of justification attainable in human knowledge was reduced at all levels. Regarding the foundation of perceptual beliefs, Russell came to admit that the object-knowledge “acquaintance with a sensedatum” was replaced by “noticing a perceptive occurrence” in An Inquiry that provides the non-inferential justification for a perceptual belief is buried under layers of “interpretation” and unconscious inference in even the earliest stages of perceptual processes. Regarding the superstructure of inferentially justified beliefs, Russell concluded in Human Knowledge that unrestricted induction is not generally truthpreserving anticipating Goodman’s “new riddle of induction”. Consideration of the work of Reichenbach and Keynes on probability led him to the conclusion that certain “postulates” are needed “to provide the antecedent probabilities required to justify inductions,” and that the only possible justification for believing these postulates lies, not in their self-evidence, but in the resultant increase in the overall coherence of one’s total belief system. In the end, Russell’s desire for certainty went unsatisfied, as he felt himself forced to the conclusion that “all human knowledge is uncertain, inexact, and partial. To this doctrine we have not found any limitation whatever.” Russell’s strictly philosophical writings of 9 and later have generally been less influential than his earlier writings. His influence was eclipsed by that of logical positivism and ordinary language philosophy. He approved of the logical positivists’ respect for logic and science, though he disagreed with their metaphysical agnosticism. But his dislike of ordinary language philosophy was visceral. In My Philosophical Development 9, he accused its practitioners of abandoning the attempt to understand the world, “that grave and important task which philosophy throughout the ages has hitherto pursued.” 

ryle: the waynflete professor of metaphysical philosophy, known especially for his contributions to the philosophy of mind and his attacks on Cartesianism. His best-known work is the masterpiece The Concept of Mind 9, an attack on what he calls “Cartesian dualism” and a defense of a type of logical behaviorism. This dualism he dubs “the dogma of the Ghost in the Machine,” the Machine being the body, which is physical and publicly observable, and the Ghost being the mind conceived as a private or secret arena in which episodes of sense perception, consciousness, and inner perception take place. A person, then, is a combination of such a mind and a body, with the mind operating the body through exercises of will called “volitions.” Ryle’s attack on this doctrine is both sharply focused and multifarious. He finds that it rests on a category mistake, namely, assimilating statements about mental processes to the same category as statements about physical processes. This is a mistake in the logic of mental statements and mental concepts and leads to the mistaken metaphysical theory that a person is composed of two separate and distinct though somehow related entities, a mind and a body. It is true that statements about the physical are statements about things and their changes. But statements about the mental are not, and in particular are not about a thing called “the mind.” These two types of statements do not belong to the same category. To show this, Ryle deploys a variety of arguments, including arguments alleging the impossibility of causal relations between mind and body and arguments alleging vicious infinite regresses. To develop his positive view on the nature of mind, Ryle studies the uses and hence the logic of mental terms and finds that mental statements tell us that the person performs observable actions in certain ways and has a disposition to perform other observable actions in specifiable circumstances. For example, to do something intelligently is to do something physical in a certain way and to adjust one’s behavior to the circumstances, not, as the dogma of the Ghost in the Machine would have it, to perform two actions, one of which is a mental action of thinking that eventually causes a separate physical action. Ryle buttresses this position with many acute and subtle analyses of the uses of mental terms. Much of Ryle’s other work concerns philosophical methodology, sustaining the thesis which is the backbone of The Concept of Mind that philosophical problems and doctrines often arise from conceptual confusion, i.e., from mistakes about the logic of language. Important writings in this vein include the influential article “Systematically Misleading Expressions” and the book Dilemmas. Ryle was also interested in Grecian philosophy throughout his life, and his last major work, Plato’s Progress, puts forward novel hypotheses about changes in Plato’s views, the role of the Academy, the purposes and uses of Plato’s dialogues, and Plato’s relations with the rulers of Syracuse.

Saint Petersburg paradox, or the return/utility distinction: a puzzle about gambling that motivated the distinction between expected return and expected utility. Bernoulli published it in a St. Petersburg journal in 1738. It concerns a gamble like this: it pays $2 if heads appears on the first toss of a coin, $4 if heads does not appear until the second toss, $8 if heads does not appear until the third toss, and so on. The expected return from the gamble is ½2 ! ¼4 ! 1 /88 ! . . . , or 1 ! 1 ! 1 ! ..., i.e., it is infinite. But no one would pay much for the gamble. So it seems that expected returns do not govern rational preferences. Bernoulli argued that expected utilities govern rational preferences. He also held that the utility of wealth is proportional to the log of the amount of wealth. Given his assumptions, the gamble has finite 808 S    808 expected utility, and should not be preferred to large sums of money. However, a twentieth-century version of the paradox, attributed to Karl Menger, reconstructs the gamble, putting utility payoffs in place of monetary payoffs, so that the new gamble has infinite expected utility. Since no one would trade much utility for the new gamble, it also seems that expected utilities do not govern rational preferences. The resolution of the paradox is under debate. 

rouvroy -- Saint-Simon, Comte de, title of Claude-Henri de Rouvroy, social reformer. An aristocrat by birth, he initially joined the ranks of the enlightened and liberal bourgeoisie. His Newtonian Letters to an Inhabitant of Geneva and Introduction to Scientific Works of the Nineteenth Century championed Condorcet’s vision of scientific and technological progress. With Auguste Comte, he shared a positivistic philosophy of history: the triumph of science over metaphysics. Written in wartime, The Reorganization of European Society urged the creation of a European parliamentary system to secure peace and unity. Having moved from scientism to pacifism, Saint-Simon moved further to industrialism. In 1817, under the influence of two theocratic thinkers, de Maistre and Bonald, Saint-Simon turned away from classical economic liberalism and repudiated laissez-faire capitalism. The Industrial System 1820 drafts the program for a hierarchical state, a technocratic society, and a planned economy. The industrial society of the future is based on the principles of productivity and cooperation and led by a rational and efficient class, the industrialists artists, scientists, and technicians. He argued that the association of positivism with unselfishness, of techniques of rational production with social solidarity and interdependency, would remedy the plight of the poor. Industrialism prefigures socialism, and socialism paves the way for the rule of the law of love, the eschatological age of The New Christianity. This utopian treatise, which reveals Saint-Simon’s alternative to reactionary Catholicism and Protestant individualism, became the Bible of the Saint-Simonians, a sectarian school of utopian socialists.                 

idem, ipse, sui, de se -- Same -- Sameness -- Griceian – One of Grice’s favourite essays ever was Wiggins’s “Sameness and substance” -- Griceian différance, a  coinage deployed by Derrida in De la Grammatologie 7, where he defines it as “an economic concept designating the production of differing/deferring.” Différance is polysemic, but its key function is to name the prime condition for the functioning of all language and thought: differing, the differentiation of signs from each other that allows us to differentiate things from each other. Deferring is the process by which signs refer to each other, thus constituting the self-reference essential to language, without ever capturing the being or presence that is the transcendent entity toward which it is aimed. Without the concepts or idealities generated by the iteration of signs, we could never identify a dog as a dog, could not perceive a dog or any other thing as such. Perception presupposes language, which, in turn, presupposes the ideality generated by the repetition of signs. Thus there can be no perceptual origin for language; language depends upon an “original repetition,” a deliberate oxymoron that Derrida employs to signal the impossibility of conceiving an origin of language from within the linguistic framework in which we find ourselves. Différance is the condition for language, and language is the condition for experience: whatever meaning we may find in the world is attributed to the differing/ deferring play of signifiers. The notion of différance and the correlative thesis that meaning is language-dependent have been appropriated by radical thinkers in the attempt to demonstrate that political inequalities are grounded in nothing other than the conventions of sign systems governing differing cultures.

sanction, anything whose function is to penalize or reward. It is useful to distinguish between social sanctions, legal sanctions, internal sanctions, and religious sanctions. Social sanctions are extralegal pressures exerted upon the agent by others. For example, others might distrust us, ostracize us, or even physically attack us, if we behave in certain ways. Legal sanctions include corporal punishment, imprisonment, fines, withdrawal of the legal rights to run a business or to leave the area, and other penalties. Internal sanctions may include not only guilt feelings but also the sympathetic pleasures of helping others or the gratified conscience of doing right. Divine sanctions, if there are any, are rewards or punishments given to us by a god while we are alive or after we die. There are important philosophical questions concerning sanctions. Should law be defined as the rules the breaking of which elicits punishment by the state? Could there be a moral duty to behave in a given way if there were no social sanctions concerning such behavior? If not, then a conventionalist account of moral duty seems unavoidable. And, to what extent does the combined effect of external and internal sanctions make rational egoism or prudence or self-interest coincide with morality?

sanctis: essential philosopher. He considers philosophy as a branch of the belles lettres – and his field of expertise is when stylists stopped using an artificial Roman, and turned to ‘Italian.’ Refs.: Luigi Speranza, "Grice e de Sanctis," per Il Club Anglo-Italiano, The Swimming-Pool Library, Villa Grice, Liguria, Italia..

sapir’s and whorf’s hypothesis, broadly, the claim that one’s perception, thought, and behavior are influenced by one’s language. The hypothesis was named after Benjamin Lee Whorf 7 1 and his teacher Edward Sapir 4 9. We may discern different versions of this claim by distinguishing degrees of linguistic influence, the highest of which is complete and unalterable determination of the fundamental structures of perception, thought, and behavior. In the most radical form, the hypothesis says that one’s reality is constructed by one’s language and that differently structured languages give rise to different realities, which are incommensurable. 

sarpi: very important Italian philosopher. Refs.: Luigi Speranza, "Grice e Sarpi," per il Club Anglo-Italiano, The Swimming-Pool Library, Villa Grice, Liguria, Italia.

sartre: Grice: “The philosopher of “Le deux magots.” – “I’m surprised Mary Warnock dedicated his life to him!” -- philosopher and writer, the leading advocate of existentialism during the years following World War II. The heart of his philosophy was the precious notion of freedom and its concomitant sense of personal responsibility. He insisted, in an interview a few years before his death, that he never ceased to believe that “in the end one is always responsible for what is made of one,” only a slight revision of his earlier, bolder slogan, “man makes himself.” To be sure, as a student of Hegel, Marx, Husserl, and Heidegger  and because of his own physical frailty and the tragedies of the war  Sartre had to be well aware of the many constraints and obstacles to human freedom, but as a Cartesian, he never deviated from Descartes’s classical portrait of human consciousness as free and distinct from the physical universe it inhabits. One is never free of one’s “situation,” Sartre tells us, though one is always free to deny “negate” that situation and to try to change it. To be human, to be conscious, is to be free to imagine, free to choose, and responsible for one’s lot in life. As a student, Sartre was fascinated by Husserl’s new philosophical method, phenomenology. His first essays were direct responses to Husserl and applications of the phenomenological method. His essay on The Imagination in 6 established the groundwork for much of what was to follow: the celebration of our remarkable freedom to imagine the world other than it is and following Kant the way that this ability informs all of our experience. In The Transcendence of the Ego 7 he reconsidered Husserl’s central idea of a “phenomenological reduction” the idea of examining the essential structures of consciousness as such and argued following Heidegger that one cannot examine consciousness without at the same time recognizing the reality of actual objects in the world. In other words, there can be no such “reduction.” In his novel Nausea 8, Sartre made this point in a protracted example: his bored and often nauseated narrator confronts a gnarled chestnut tree in the park and recognizes with a visceral shock that its presence is simply given and utterly irreducible. In The Transcendence of the Ego Sartre also reconsiders the notion of the self, which Husserl and so many earlier philosophers had identified with consciousness. But the self, Sartre argues, is not “in” consciousness, much less identical to it. The self is out there “in the world, like the self of another.” In other words, the self is an ongoing project in the world with other people; it is not simply self-awareness or self-consciousness as such “I think, therefore I am”. This separation of self and consciousness and the rejection of the self as simply self-consciousness provide the framework for Sartre’s greatest philosophical treatise, L’être et le néant Being and Nothingness, 3. Its structure is unabashedly Cartesian, consciousness “being-for-itself” or pour soi on the one side, the existence of mere things “being-in-itself” or en soi on the other. The phraseology comes from Hegel. But Sartre does not fall into the Cartesian trap of designating these two types of being as separate “substances.” Instead, Sartre describes consciousness as “nothing’  “not a thing” but an activity, “a wind blowing from nowhere toward the world.” Sartre often resorts to visceral metaphors when developing this theme e.g., “a worm coiled in the heart of being”, but much of what he is arguing is familiar to philosophical readers in the more metaphor-free work of Kant, who also warned against the follies “paralogisms” of understanding consciousness as itself a possible object of consciousness rather than as the activity of constituting the objects of consciousness. As the lens of a camera can never see itself  and in a mirror only sees a reflection of itself  consciousness can never view itself as consciousness and is only aware of itself  “for itself”  through its experience of objects. Ontologically, one might think of “nothingness” as “no-thing-ness,” a much less outrageous suggestion than those that would make it an odd sort of a thing. It is through the nothingness of consciousness and its activities that negation comes into the world, our ability to imagine the world other than it is and the inescapable necessity of imagining ourselves other than we seem to be. And because consciousness is nothingness, it is not subject to the rules of causality. Central to the argument of L’être et le néant and Sartre’s insistence on the primacy of human freedom is his insistence that consciousness cannot be understood in causal terms. It is always self-determining and, as such, “it always is what it is not, and is not what it is”  a playful paradox that refers to the fact that we are always in the process of choosing. Consciousness is “nothing,” but the self is always on its way to being something. Throughout our lives we accumulate a body of facts that are true of us  our “facticity”  but during our lives we remain free to envision new possibilities, to reform ourselves and to reinterpret our facticity in the light of new projects and ambitions  our “transcendence.” This indeterminacy means that we can never be anything, and when we try to establish ourselves as something particular  whether a social role policeman, waiter or a certain character shy, intellectual, cowardly  we are in “bad faith.” Bad faith is erroneously viewing ourselves as something fixed and settled Sartre utterly rejects Freud and his theory of the unconscious determination of our personalities and behavior, but it is also bad faith to view oneself as a being of infinite possibilities and ignore the always restrictive facts and circumstances within which all choices must be made. On the one hand, we are always trying to define ourselves; on the other hand we are always free to break away from what we are, and always responsible for what we have made of ourselves. But there is no easy resolution or “balance” between facticity and freedom, rather a kind of dialectic or tension. The result is our frustrated desire to be God, to be both in-itself and for-itself. But this is not so much blasphemy as an expression of despair, a form of ontological original sin, the impossibility of being both free and what we want to be. Life for Sartre is yet more complicated. There is a third basic ontological category, on a par with the being-in-itself and being-for-itself and not derivative of them. He calls it “being-for-others.” To say that it is not derivative is to insist that our knowledge of others is not inferred, e.g. by some argument by analogy, from the behavior of others, and we ourselves are not wholly constituted by our self-determinations and the facts about us. Sartre gives us a brutal but familiar everyday example of our experience of being-for-others in what he calls “the look” le regard. Someone catches us “in the act” of doing something humiliating, and we find ourselves defining ourselves probably also resisting that definition in their terms. In his Saint Genet 3, Sartre describes such a conversion of the ten-year-old Jean Genet into a thief. So, too, we tend to “catch” one another in the judgments we make and define one another in terms that are often unflattering. But these judgments become an essential and ineluctible ingredient in our sense of ourselves, and they too lead to conflicts indeed, conflicts so basic and so frustrating that in his play Huis clos No Exit, 3 Sartre has one of his characters utter the famous line, “Hell is other people.” In his later works, notably his Critique of Dialectical Reason 859, Sartre turned increasingly to politics and, in particular, toward a defense of Marxism on existentialist principles. This entailed rejecting materialist determinism, but it also required a new sense of solidarity or what Sartre had wistfully called, following Heidegger, Mitsein or “being with others”. Thus in his later work he struggled to find a way of overcoming the conflict and insularity or the rather “bourgeois” consciousness he had described in Being and Nothingness. Not surprisingly given his constant political activities he found it in revolutionary engagement. Consonant with his rejection of bourgeois selfhood, Sartre turned down the 4 Nobel prize for literature. 

satisfactoriness-condition: a state of affairs or “way things are,” most commonly referred to in relation to something that implies or is implied by it. Let p, q, and r be schematic letters for declarative sentences; and let P, Q, and R be corresponding nominalizations; e.g., if p is ‘snow is white’, then P would be ‘snow’s being white’. P can be a necessary or sufficient condition of Q in any of several senses. In the weakest sense P is a sufficient condition of Q iff if and only if: if p then q or if P is actual then Q is actual  where the conditional is to be read as “material,” as amounting merely to not-p & not-q. At the same time Q is a necessary condition of P iff: if not-q then not-p. It follows that P is a sufficient condition of Q iff Q is a necessary condition of P. Stronger senses of sufficiency and of necessity are definable, in terms of this basic sense, as follows: P is nomologically sufficient necessary for Q iff it follows from the laws of nature, but not without them, that if p then q that if q then p. P is alethically or metaphysically sufficient necessary for Q iff it is alethically or metaphysically necessary that if p then q that if q then p. However, it is perhaps most common of all to interpret conditions in terms of subjunctive conditionals, in such a way that P is a sufficient condition of Q iff P would not occur unless Q occurred, or: if P should occur, Q would; and P is a necessary condition of Q iff Q would not occur unless P occurred, or: if Q should occur, P would.  -- satisfaction, an auxiliary semantic notion introduced by Tarski in order to give a recursive definition of truth for languages containing quantifiers. Intuitively, the satisfaction relation holds between formulas containing free variables such as ‘Buildingx & Tallx’ and objects or sequences of objects such as the Empire State Building if and only if the formula “holds of” or “applies to” the objects. Thus, ‘Buildingx & Tallx’, is satisfied by all and only tall buildings, and ‘-Tallx1 & Tallerx1, x2’ is satisfied by any pair of objects in which the first object corresponding to ‘x1’ is not tall, but nonetheless taller than the second corresponding to ‘x2’. Satisfaction is needed when defining truth for languages with sentences built from formulas containing free variables, because the notions of truth and falsity do not apply to these “open” formulas. Thus, we cannot characterize the truth of the sentences ‘Dx Buildingx & Tallx’ ‘Some building is tall’ in terms of the truth or falsity of the open formula ‘Buildingx & Tallx’, since the latter is neither true nor false. But note that the sentence is true if and only if the formula is satisfied by some object. Since we can give a recursive definition of the notion of satisfaction for possibly open formulas, this enables us to use this auxiliary notion in defining truth.  -- satisfiable, having a common model, a structure in which all the sentences in the set are true; said of a set of sentences. In modern logic, satisfiability is the semantic analogue of the syntactic, proof-theoretic notion of consistency, the unprovability of any explicit contradiction. The completeness theorem for first-order logic, that all valid sentences are provable, can be formulated in terms of satisfiability: syntactic consistency implies satisfiability. This theorem does not necessarily hold for extensions of first-order logic. For any sound proof system for secondorder logic there will be an unsatisfiable set of sentences without there being a formal derivation of a contradiction from the set. This follows from Gödel’s incompleteness theorem. One of the central results of model theory for first-order logic concerns satisfiability: the compactness theorem, due to Gödel in 6, says that if every finite subset of a set of sentences is satisfiable the set itself is satisfiable. It follows immediately from his completeness theorem for first-order logic, and gives a powerful method to prove the consistency of a set of sentences. 

satisfice: to choose or do the good enough rather than the most or the best. ‘Satisfice’, an obsolete variant of ‘satisfy’ (“much as ‘implicate’ is an explicated form of ‘imply’” – Grice) has been adopted by Simon and others to designate nonoptimizing choice or action. According to some economists, limitations of time or information may make it impossible or inadvisable for an individual, firm, or state body to attempt to maximize pleasure, profits, market share, revenues, or some other desired result, and satisficing with respect to such results is then said to be rational, albeit less than ideally rational. Although many orthodox economists think that choice can and always should be conceived in maximizing or optimizing terms, satisficing models have been proposed in economics, evolutionary biology, and philosophy. Biologists have sometimes conceived evolutionary change as largely consisting of “good enough” or satisficing adaptations to environmental pressures rather than as proceeding through optimal adjustments to such pressures, but in philosophy, the most frequent recent use of the idea of satisficing has been in ethics and rational choice theory. Economists typically regard satisficing as acceptable only where there are unwanted constraints on decision making; but it is also possible to see satisficing as entirely acceptable in itself, and in the field of ethics, it has recently been argued that there may be nothing remiss about moral satisficing, e.g., giving a good amount to charity, but less than one could give. It is possible to formulate satisficing forms of utilitarianism on which actions are morally right even if they contribute merely positively and/or in some large way, rather than maximally, to overall net human happiness. Bentham’s original formulation of the principle of utility and Popper’s negative utilitarianism are both examples of satisficing utilitarianism in this sense  and it should be noted that satisficing utilitarianism has the putative advantage over optimizing forms of allowing for supererogatory degrees of moral excellence. Moreover, any moral view that treats moral satisficing as permissible makes room for moral supererogation in cases where one optimally goes beyond the merely acceptable. But since moral satisficing is less than optimal moral behavior, but may be more meritorious than certain behavior that in the same circumstances would be merely permissible, some moral satisficing may actually count as supererogatory. In recent work on rational individual choice, some philosophers have argued that satisficing may often be acceptable in itself, rather than merely second-best. Even Simon allows that an entrepreneur may simply seek a satisfactory return on investment or share of the market, rather than a maximum under one of these headings. But a number of philosophers have made the further claim that we may sometimes, without irrationality, turn down the readily available better in the light of the goodness and sufficiency of what we already have or are enjoying. Independently of the costs of taking a second dessert, a person may be entirely satisfied with what she has eaten and, though willing to admit she would enjoy that extra dessert, turn it down, saying “I’m just fine as I am.” Whether such examples really involve an acceptable rejection of the momentarily better for the good enough has been disputed. However, some philosophers have gone on to say, even more strongly, that satisficing can sometimes be rationally required and optimizing rationally unacceptable. To keep on seeking pleasure from food or sex without ever being thoroughly satisfied with what one has enjoyed can seem compulsive and as such less than rational. If one is truly rational about such goods, one isn’t insatiable: at some point one has had enough and doesn’t want more, even though one could obtain further pleasure. The idea that satisficing is sometimes a requirement of practical reason is reminiscent of Aristotle’s view that moderation is inherently reasonable  rather than just a necessary means to later enjoyments and the avoidance of later pain or illness, which is the way the Epicureans conceived moderation. But perhaps the greatest advocate of satisficing is Plato, who argues in the Philebus that there must be measure or limit to our desire for pleasure in order for pleasure to count as a good thing for us. Insatiably to seek and obtain pleasure from a given source is to gain nothing good from it. And according to such a view, satisficing moderation is a necessary precondition of human good and flourishing, rather than merely being a rational restraint on the accumulation of independently conceived personal good or well-being.

saussure: founder of structuralism. His work in semiotics is a major influence on the later development of  structuralist philosophy, as well as structural anthropology, structuralist literary criticism, and modern semiology. He pursued studies in linguistics largely under Georg Curtius at the  of Leipzig, along with such future Junggrammatiker neogrammarians as Leskien and Brugmann. Following the publication of his important Mémoire sur le système primitif des voyelles dans les langues indo-européenes 1879, Saussure left for Paris, where he associated himself with the Société Linguistique and taught comparative grammar. In 1, he returned to Switzerland to teach Sanskrit, comparative grammar, and general linguistics at the  of Geneva. His major work, the Course in General Linguistics 6, was assembled from students’ notes and his original lecture outlines after his death. The Course in General Linguistics argued against the prevalent historical and comparative philological approaches to language by advancing what Saussure termed a scientific model for linguistics, one borrowed in part from Durkheim. Such a model would take the “social fact” of language la langue as its object, and distinguish this from the variety of individual speech events la parole, as well as from the collectivity of speech events and grammatical rules that form the general historical body of language as such le langage. Thus, by separating out the unique and accidental elements of practiced speech, Saussure distinguished language la langue as the objective set of linguistic elements and rules that, taken as a system, governs the language use specific to a given community. It was the systematic coherency and generality of language, so conceived, that inclined Saussure to approach linguistics principally in terms of its static or synchronic dimension, rather than its historical or diachronic dimension. For Saussure, the system of language is a “treasury” or “depository” of signs, and the basic unit of the linguistic sign is itself two-sided, having both a phonemic component “the signifier” and a semantic component “the signified”. He terms the former the “acoustical” or “sound” image  which may, in turn, be represented graphically, in writing  and the latter the “concept” or “meaning.” Saussure construes the signifier to be a representation of linguistic sounds in the imagination or memory, i.e., a “psychological phenomenon,” one that corresponds to a specifiable range of material phonetic sounds. Its distinctive property consists in its being readily differentiated from other signifiers in the particular language. It is the function of each signifier, as a distinct entity, to convey a particular meaning  or “signified” concept  and this is fixed purely by conventional association. While the relation between the signifier and signified results in what Saussure terms the “positive” fact of the sign, the sign ultimately derives its linguistic value its precise descriptive determination from its position in the system of language as a whole, i.e., within the paradigmatic and syntagmatic relations that structurally and functionally differentiate it. Signifiers are differentially identified; signifiers are arbitrarily associated with their respective signified concepts; and signs assume the determination they do only through their configuration within the system of language as a whole: these facts enabled Saussure to claim that language is largely to be understood as a closed formal system of differences, and that the study of language would be principally governed by its autonomous structural determinations. So conceived, linguistics would be but a part of the study of social sign systems in general, namely, the broader science of what Saussure termed semiology. Saussure’s insights would be taken up by the subsequent Geneva, Prague, and Copenhagen schools of linguistics and by the Russian formalists, and would be further developed by the structuralists in France and elsewhere, as well as by recent semiological approaches to literary criticism, social anthropology, and psychoanalysis. Grice was influenced by de Saussure via Ogden’s and Richard’s Meaning of Meaning and Gardiner’s “Theory of Speech and Language.”

saxonia: “Strictly, if we call William of Occam, Occam, we should call Albert of Saxony, Saxony.” “Saxonia sounds like a large place – but we do not know where in Saxony came from – I often wonder if Albertus of Saxony is not underinformative.” – Grice. Like Grice, a terminist logician, from lower Saxony who taught in the arts faculty at Paris. Under the influence of Buridan and Nicholas of Oresme, he turned to playful dialectics. He was a founder of the “Universitas Vienna” and was bishop of Halberstadt. His works on logic include Logic, Questions on the Posterior Analytics, Sophismata, Treatise on Obligations, and Insolubilia. He also wrote questions on Aristotle’s physical works and on John of Sacrobosco’s De Sphaera, and short treatises on squaring the circle and on the ratio of the diameter to the side of a square. His work is competent but rarely original. Grice read most of them, and was surprised that Albertus never coined ‘implicaturum’!

sceptis: Cicero translated as ‘dubitatio.’ For some reason, Grice was irritated by Wood’s sobriquet of Russell as a “passionate sceptic”: ‘an oxymoron.” The most specific essay by Grice on this is an essay he kept after many years, that he delivered back in the day at Oxford, entitled, “Scepticism and common sense.” Both were traditional topics at Oxford at the time. Typically, as in the Oxonian manner, he chose two authors, New-World’s Malcolm’s treatment of Old-World Moore, and brings in Austin’s ‘ordinary-language’ into the bargain. He also brings in his own obsession with what an emissor communicates. In this case, the “p” is the philosopher’s sceptical proposition, such as “That pillar box is red.” Grice thinks ‘dogmatic’ is the opposite of ‘sceptic,’ and he is right! Liddell and Scott have “δόγμα,” from “δοκέω,” and which they render as “that which seems to one, opinion or belief;” Pl.R.538c; “δ. πόλεως κοινόν;” esp. of philosophical doctrines, Epicur.Nat.14.7; “notion,” Pl.Tht.158d; “decision, judgement,” Pl. Lg.926d; (pl.); public decree, ordinance,  esp. of Roman Senatus-consulta, “δ. συγκλήτου”  “δ. τῆς βουλῆς” So note that there is nothing ‘dogmatic’ about ‘dogma,’ as it derives from ‘dokeo,’ and is rendered as ‘that which seems to one.’ So the keyword should be later Grecian, and in the adjectival ‘dogmatic.’ Liddell and Scott have “δογματικός,” which they render as “of or for doctrines, didactic, [διάλογοι] Quint.Inst.2.15.26, and “of persons, δ. ἰατροί,” “physicians who go by general principles,” opp. “ἐμπειρικοί and μεθοδικοί,” Dsc.Ther.Praef., Gal.1.65; in Philosophy, S.E.M.7.1, D.L.9.70, etc.; “δ. ὑπολήψεις” Id.9.83; “δ. φιλοσοφία” S.E. P.1.4. Adv. “-κῶς” D.L.9.74, S.E.P.1.197: Comp. “-κώτερον” Id.M. 6.4. Why is Grice interested in scepticism. His initial concern, the one that Austin would authorize, relates to ‘ordinary language.’ What if ‘ordinary language’ embraces scepticism? What if it doesn’t? Strawso notes that the world of ordinary language is a world of things, causes, and stuff. None of the good stuff for the sceptic. what is Grice’s answer to the sceptic’s implicaturum? The sceptic’s implicaturum is a topic that always fascinated Girce. While Grice groups two essays as dealing with one single theme, strictly, only this or that philosopher’s paradox (not all) may count as sceptical. This or that philosopher’s paradox may well not be sceptical at all but rather dogmatic. In fact, Grice defines philosophers paradox as anything repugnant to common sense, shocking, or extravagant ‒ to Malcolms ears, that is! While it is, strictly, slightly odd to quote this as a given date just because, by a stroke of the pen, Grice writes that date in the Harvard volume, we will follow his charming practice. This is vintage Grice. Grice always takes the sceptics challenge seriously, as any serious philosopher should. Grices takes both the sceptics explicatum and the scepticss implicaturum as self-defeating, as a very affront to our idea of rationality, conversational or other. V: Conversations with a sceptic: Can he be slightly more conversational helpful? Hume’ sceptical attack is partial, and targeted only towards practical reason, though.  Yet, for Grice, reason is one. You cannot really attack practical or buletic reason without attacking theoretical or doxastic reason. There is such thing as a general rational acceptance, to use Grice’s term, that the sceptic is getting at. Grice likes to play with the idea that ultimately every syllogism is buletic or practical. If, say, a syllogism by Eddington looks doxastic, that is because Eddington cares to omit the practical tail, as Grice puts it. And Eddington is not even a philosopher, they say. Grice is here concerned with a Cantabrigian topic popularised by Moore. As Grice recollects, Some like Witters, but Moore’s my man. Unlike Cambridge analysts such as Moore, Grice sees himself as a linguistic-turn Oxonian analyst. So it is only natural that Grice would connect time-honoured scepticism of Pyrrhos vintage, and common sense with ordinary language, so mis-called, the elephant in Grices room. Lewis and Short have “σκέψις,” f. σκέπτομαι, which they render as “viewing, perception by the senses, ἡ διὰ τῶν ὀμμάτων ςκέψις, Pl. Phd. 83a; observation of auguries; also as examination, speculation, consideration, τὸ εὕρημα πολλῆς σκέψιος; βραχείας ςκέψις; ϝέμειν ςκέψις take thought of a thing; ἐνθεὶς τῇ τέχνῃ ςκέψις; ςκέψις ποιεῖσθαι; ςκέψις προβέβληκας; ςκέψις λόγων; ςκέψις περί τινος inquiry into, speculation on a thing; περί τι Id. Lg. 636d;ἐπὶ σκέψιν τινὸς ἐλθεῖν; speculation, inquiry,ταῦτα ἐξωτερικωτέρας ἐστὶ σκέψεως; ἔξω τῆς νῦν ςκέψεως; οὐκ οἰκεῖα τῆς παρούσης ςκέψις; also hesitation, doubt, esp. of the Sceptic or Pyrthonic philosophers, AP 7. 576 (Jul.); the Sceptic philosophy, S. E. P. 1.5; οἱ ἀπὸ τῆς ςκέψεως, the Sceptics, ib. 229. in politics, resolution, decree, συνεδρίον Hdn. 4.3.9, cf. Poll. 6.178. If scepticism attacks common sense and fails, Grice seems to be implicating, that ordinary language philosophy is a good antidote to scepticism. Since what language other than ordinary language does common sense speak? Well, strictly, common sense doesnt speak. The man in the street does. Grice addresses this topic in a Mooreian way in a later essay, also repr. in Studies, Moore and philosophers paradoxes, repr. in Studies. As with his earlier Common sense and scepticism, Grice tackles Moores and Malcolms claim that ordinary language, so-called, solves a few of philosophers paradoxes. Philosopher is Grices witty way to generalise over your common-or-garden, any, philosopher, especially of the type he found eccentric, the sceptic included. Grice finds this or that problem in this overarching Cantabrigian manoeuvre, as over-simplifying a pretty convoluted terrain. While he cherishes Austins Some like Witters, but Moores MY man! Grice finds Moore too Cantabrigian to his taste. While an Oxonian thoroughbred, Grice is a bit like Austin, Some like Witters, but Moores my man, with this or that caveat. Again, as with his treatment of Descartes or Locke, Grice is hardly interested in finding out what Moore really means. He is a philosopher, not a historian of philosophy, and he knows it. While Grice agrees with Austins implicaturum that Moore goes well above Witters, if that is the expression (even if some like him), we should find the Oxonian equivalent to Moore. Grice would not Names Ryle, since he sees him, and his followers, almost every day. There is something apostolic about Moore that Grice enjoys, which is just as well, seeing that Moore is one of the twelve. Grice found it amusing that the members of The Conversazione Society would still be nickNamesd apostles when their number exceeded the initial 12. Grice spends some time exploring what Malcolm, a follower of Witters, which does not help, as it were, has to say about Moore in connection with that particularly Oxonian turn of phrase, such as ordinary language is. For Malcolms Moore, a paradox by philosopher [sic], including the sceptic, arises when philosopher [sic], including the sceptic, fails to abide by the dictates of ordinary language. It might merit some exploration if Moore’s defence of common sense is against: the sceptic may be one, but also the idealist. Moore the realist, armed with ordinary language attacks the idealists claim. The idealist is sceptical of the realists claim. But empiricist idealism (Bradley) has at Oxford as good pedigree as empiricist realism (Cook Wilson). Malcolm’s simplifications infuriate Grice, and ordinary language has little to offer in the defense of common sense realism against sceptical empiricist idealism. Surely the ordinary man says ridiculous, or silly, as Russell prefers, things, such as Smith is lucky, Departed spirits walk along this road on their way to Paradise, I know there are infinite stars, and I wish I were Napoleon, or I wish that I had been Napoleon, which does not mean that the utterer wishes that he were like Napoleon, but that he wishes that he had lived not in the his century but in the XVIIIth century. Grice is being specific about this. It is true that an ordinary use of language, as Malcolm suggests, cannot be self-contradictory unless the ordinary use of language is defined by stipulation as not self-contradictory, in which case an appeal to ordinary language becomes useless against this or that paradox by Philosopher. I wish that I had been Napoleon seems to involve nothing but an ordinary use of language by any standard but that of freedom from absurdity. I wish that I had been Napoleon is not, as far as Grice can see, philosophical, but something which may have been said and meant by numbers of ordinary people. Yet, I wish that I had been Napoleon is open to the suspicion of self-contradictoriness, absurdity, or some other kind of meaninglessness. And in this context suspicion is all Grice needs. By uttering I wish that I had been Napoleon U hardly means the same as he would if he uttered I wish I were like Napoleon. I wish that I had been Napoleon is suspiciously self-contradictory, absurd, or meaningless, if, as uttered by an utterer in a century other than the XVIIIth century, say, the utterer is understood as expressing the proposition that the utterer wishes that he had lived in the XVIIIth century, and not in his century, in which case he-1 wishes that he had not been him-1? But blame it on the buletic. That Moore himself is not too happy with Malcolms criticism can be witnessed by a cursory glimpse at hi reply to Malcolm. Grice is totally against this view that Malcolm ascribes to Moore as a view that is too broad to even claim to be true. Grices implicaturum is that Malcolm is appealing to Oxonian turns of phrase, such as ordinary language, but not taking proper Oxonian care in clarifying the nuances and stuff in dealing with, admittedly, a non-Oxonian philosopher such as Moore. When dealing with Moore, Grice is not necessarily concerned with scepticism. Time is unreal, e.g. is hardly a sceptic utterance. Yet Grice lists it as one of Philosophers paradoxes. So, there are various to consider here. Grice would start with common sense. That is what he does when he reprints this essay in WOW, with his attending note in both the preface and the Retrospective epilogue on how he organizes the themes and strands. Common sense is one keyword there, with its attending realism. Scepticism is another, with its attending empiricist idealism. It is intriguing that in the first two essays opening Grices explorations in semantics and metaphysics it seems its Malcolm, rather than the dryer Moore, who interests Grice most. While he would provide exegeses of this or that dictum by Moore, and indeed, Moore’s response to Malcolm, Grice seems to be more concerned with applications of his own views. Notably in Philosophers paradoxes. The fatal objection Grice finds for the paradox propounder (not necessarily a sceptic, although a sceptic may be one of the paradox propounders) significantly rests on Grices reductive analysis of meaning that  as ascribed to this or that utterer U. Grice elaborates on circumstances that hell later take up in the Retrospective epilogue. I find myself not understanding what I mean is dubiously acceptable. If meaning, Grice claims, is about an utterer U intending to get his addressee A to believe that U ψ-s that p, U must think there is a good chance that A will recognise what he is supposed to believe, by, perhaps, being aware of the Us practice or by a supplementary explanation which might come from U. In which case, U should not be meaning what Malcolm claims U might mean. No utterer should intend his addressee to believe what is conceptually impossible, or incoherent, or blatantly false (Charles Is decapitation willed Charles Is death.), unless you are Queen in Through the Looking Glass. I believe five impossible things before breakfast, and I hope youll soon get the proper training to follow suit. Cf. Tertulian, Credo, quia absurdum est. Admittedly, Grice edits the Philosophers paradoxes essay. It is only Grices final objection which is repr. in WOW, even if he provides a good detailed summary of the previous sections. Grice appeals to Moore on later occasions. In Causal theory, Grice lists, as a third philosophical mistake, the opinion by Malcolm that Moore did not know how to use knowin a sentence. Grice brings up the same example again in Prolegomena. The use of factive know of Moore may well be a misuse. While at Madison, Wisconsin, Moore lectures at a hall eccentrically-built with indirect lighting simulating sun rays, Moore infamously utters, I know that there is a window behind that curtain, when there is not. But it is not the factiveness Grice is aiming at, but the otiosity Malcolm misdescribes in the true, if baffling, I know that I have two hands. In Retrospective epilogue, Grice uses M to abbreviate Moore’s fairy godmother – along with G (Grice), A (Austin), R (Ryle) and Q (Quine)! One simple way to approach Grices quandary with Malcolm’s quandary with Moore is then to focus on know. How can Malcolm claim that Moore is guilty of misusing know? The most extensive exploration by Grice on know is in Grices third James lecture (but cf. his seminar on Knowledge and belief, and his remarks on some of our beliefs needing to be true, in Meaning revisited. The examinee knows that the battle of Waterloo was fought in 1815. Nothing odd about that, nor about Moores uttering I know that these are my hands. Grice is perhaps the only one of the Oxonian philosophers of Austins play group who took common sense realsim so seriously, if only to crticise Malcoms zeal with it. For Grice, common-sense realism = ordinary language, whereas for the typical Austinian, ordinary language = the language of the man in the street. Back at Oxford, Grice uses Malcolm to contest the usual criticism that Oxford ordinary-language philosophers defend common-sense realist assumptions just because the way non-common-sense realist philosopher’s talk is not ordinary language, and even at Oxford. Cf. Flews reference to Joness philosophical verbal rubbish in using self as a noun. Grice is infuriated by all this unclear chatter, and chooses Malcolms mistreatment of Moore as an example. Grice is possibly fearful to consider Austins claims directly! In later essays, such as ‘the learned’ and ‘the lay,’ Grice goes back to the topic criticising now the scientists jargon as an affront to the ordinary language of the layman that Grice qua philosopher defends. scepticism, in the most common sense, the refusal to grant that there is any knowledge or justification. Skepticism can be either partial or total, either practical or theoretical, and, if theoretical, either moderate or radical, and either of knowledge or of justification. Skepticism is partial iff if and only if it is restricted to particular fields of beliefs or propositions, and total iff not thus restricted. And if partial, it may be highly restricted, as is the skepticism for which religion is only opium, or much more general, as when not only is religion called opium, but also history bunk and metaphysics meaningless. Skepticism is practical iff it is an attitude of deliberately withholding both belief and disbelief, accompanied perhaps but not necessarily by commitment to a recommendation for people generally, that they do likewise. Practical skepticism can of course be either total or partial, and if partial it can be more or less general. Skepticism is theoretical iff it is a commitment to the belief that there is no knowledge justified belief of a certain kind or of certain kinds. Such theoretical skepticism comes in several varieties. It is moderate and total iff it holds that there is no certain superknowledge superjustified belief whatsoever, not even in logic or mathematics, nor through introspection of one’s present experience. It is radical and total iff it holds that there isn’t even any ordinary knowledge justified belief at all. It is moderate and partial, on the other hand, iff it holds that there is no certain superknowledge superjustified belief of a certain specific kind K or of certain specific kinds K1, . . . , Kn less than the totality of such kinds. It is radical and partial, finally, iff it holds that there isn’t even any ordinary knowledge justified belief at all of that kind K or of those kinds K1, . . . , Kn. Grecian skepticism can be traced back to Socrates’ epistemic modesty. Suppressed by the prolific theoretical virtuosity of Plato and Aristotle, such modesty reasserted itself in the skepticism of the Academy led by Arcesilaus and later by Carneades. In this period began a long controversy pitting Academic Skeptics against the Stoics Zeno and later Chrysippus, and their followers. Prolonged controversy, sometimes heated, softened the competing views, but before agreement congealed Anesidemus broke with the Academy and reclaimed the arguments and tradition of Pyrrho, who wrote nothing, but whose Skeptic teachings had been preserved by a student, Timon in the third century B.C.. After enduring more than two centuries, neoPyrrhonism was summarized, c.200 A.D., by Sextus Empiricus Outlines of Pyrrhonism and Adversus mathematicos. Skepticism thus ended as a school, but as a philosophical tradition it has been influential long after that, and is so even now. It has influenced strongly not only Cicero Academica and De natura deorum, St. Augustine Contra academicos, and Montaigne “Apology for Raimund Sebond”, but also the great historical philosophers of the Western tradition, from Descartes through Hegel. Both on the Continent and in the Anglophone sphere a new wave of skepticism has built for decades, with logical positivism, deconstructionism, historicism, neopragmatism, and relativism, and the writings of Foucault knowledge as a mask of power, Derrida deconstruction, Quine indeterminacy and eliminativism, Kuhn incommensurability, and Rorty solidarity over objectivity, edification over inquiry. At the same time a rising tide of books and articles continues other philosophical traditions in metaphysics, epistemology, ethics, etc. It is interesting to compare the cognitive disengagement recommended by practical skepticism with the affective disengagement dear to stoicism especially in light of the epistemological controversies that long divided Academic Skepticism from the Stoa, giving rise to a rivalry dominant in Hellenistic philosophy. If believing and favoring are positive, with disbelieving and disfavoring their respective negative counterparts, then the magnitude of our happiness positive or unhappiness negative over a given matter is determined by the product of our belief/disbelief and our favoring/disfavoring with regard to that same matter. The fear of unhappiness may lead one stoically to disengage from affective engagement, on either side of any matter that escapes one’s total control. And this is a kind of practical affective “skepticism.” Similarly, if believing and truth are positive, with disbelieving and falsity their respective negative counterparts, then the magnitude of our correctness positive or error negative over a given matter is determined by the product of our belief/disbelief and the truth/falsity with regard to that same matter where the positive or negative magnitude of the truth or falsity at issue may be determined by some measure of “theoretical importance,” though alternatively one could just assign all truths a value of !1 and all falsehoods a value of †1. The fear of error may lead one skeptically to disengage from cognitive engagement, on either side of any matter that involves risk of error. And this is “practical cognitive skepticism.” We wish to attain happiness and avoid unhappiness. This leads to the disengagement of the stoic. We wish to attain the truth and avoid error. This leads to the disengagement of the skeptic, the practical skeptic. Each opts for a conservative policy, but one that is surely optional, given just the reasoning indicated. For in avoiding unhappiness the stoic also forfeits a corresponding possibility of happiness. And in avoiding error the skeptic also forfeits a corresponding possibility to grasp a truth. These twin policies appeal to conservatism in our nature, and will reasonably prevail in the lives of those committed to avoiding risk as a paramount objective. For this very desire must then be given its due, if we judge it rational. Skepticism is instrumental in the birth of modern epistemology, and modern philosophy, at the hands of Descartes, whose skepticism is methodological but sophisticated and well informed by that of the ancients. Skepticism is also a main force, perhaps the main force, in the broad sweep of Western philosophy from Descartes through Hegel. Though preeminent in the history of our subject, skepticism since then has suffered decades of neglect, and only in recent years has reclaimed much attention and even applause. Some recent influential discussions go so far as to grant that we do not know we are not dreaming. But they also insist one can still know when there is a fire before one. The key is to analyze knowledge as a kind of appropriate responsiveness to its object truth: what is required is that the subject “track” through his belief the truth of what he believes. S tracks the truth of P iff: S would not believe P if P were false. Such an analysis of tracking, when conjoined with the view of knowledge as tracking, enables one to explain how one can know about the fire even if for all one knows it is just a dream. The crucial fact here is that even if P logically entails Q, one may still be able to track the truth of P though unable to track the truth of Q. Nozick, Philosophical Explanations, 1. Many problems arise in the literature on this approach. One that seems especially troubling is that though it enables us to understand how contingent knowledge of our surroundings is possible, the tracking account falls short of enabling an explanation of how such knowledge on our part is actual. To explain how one knows that there is a fire before one F, according to the tracking account one presumably would invoke one’s tracking the truth of F. But this leads deductively almost immediately to the claim that one is not dreaming: Not D. And this is not something one can know, according to the tracking account. So how is one to explain one’s justification for making that claim? Most troubling of all here is the fact that one is now cornered by the tracking account into making combinations of claims of the following form: I am quite sure that p, but I have no knowledge at all as to whether p. And this seems incoherent. A Cartesian dream argument that has had much play in recent discussions of skepticism is made explicit by Barry Stroud, The Significance of Philosophical Scepticism, 4 as follows. One knows that if one knows F then one is not dreaming, in which case if one really knows F then one must know one is not dreaming. However, one does not know one is not dreaming. So one does not know F. Q.E.D. And why does one fail to know one is not dreaming? Because in order to know it one would need to know that one has passed some test, some empirical procedure to determine whether one is dreaming. But any such supposed test  say, pinching oneself  could just be part of a dream, and dreaming one passes the test would not suffice to show one was not dreaming. However, might one not actually be witnessing the fire, and passing the test  and be doing this in wakeful life, not in a dream  and would that not be compatible with one’s knowing of the fire and of one’s wakefulness? Not so, according to the argument, since in order to know of the fire one needs prior knowledge of one’s wakefulness. But in order to know of one’s wakefulness one needs prior knowledge of the results of the test procedure. But this in turn requires prior knowledge that one is awake and not dreaming. And we have a vicious circle. We might well hold that it is possible to know one is not dreaming even in the absence of any positive test result, or at most in conjunction with coordinate not prior knowledge of such a positive indication. How in that case would one know of one’s wakefulness? Perhaps one would know it by believing it through the exercise of a reliable faculty. Perhaps one would know it through its coherence with the rest of one’s comprehensive and coherent body of beliefs. Perhaps both. But, it may be urged, if these are the ways one might know of one’s wakefulness, does not this answer commit us to a theory of the form of A below? A The proposition that p is something one knows believes justifiably if and only if one satisfies conditions C with respect to it. And if so, are we not caught in a vicious circle by the question as to how we know  what justifies us in believing  A itself? This is far from obvious, since the requirement that we must submit to some test procedure for wakefulness and know ourselves to test positively, before we can know ourselves to be awake, is itself a requirement that seems to lead equally to a principle such as A. At least it is not evident why the proposal of the externalist or of the coherentist as to how we know we are awake should be any more closely related to a general principle like A than is the foundationalist? notion that in order to know we are awake we need epistemically prior knowledge that we test positive in a way that does not presuppose already acquired knowledge of the external world. The problem of how to justify the likes of A is a descendant of the infamous “problem of the criterion,” reclaimed in the sixteenth century and again in this century by Chisholm, Theory of Knowledge, 6, 7, and 8 but much used already by the Skeptics of antiquity under the title of the diallelus. About explanations of our knowledge or justification in general of the form indicated by A, we are told that they are inadequate in a way revealed by examples like the following. Suppose we want to know how we know anything at all about the external world, and part of the answer is that we know the location of our neighbor by knowing the location of her car in her driveway. Surely this would be at best the beginning of an answer that might be satisfactory in the end if recursive, e.g., but as it stands it cannot be satisfactory without supplementation. The objection here is based on a comparison between two appeals: the appeal of a theorist of knowledge to a principle like A in the course of explaining our knowledge or justification in general, on one side; and the appeal to the car’s location in explaining our knowledge of facts about the external world, on the other side. This comparison is said to be fatal to the ambition to explain our knowledge or justification in general. But are the appeals relevantly analogous? One important difference is this. In the example of the car, we explain the presence, in some subject S, of a piece of knowledge of a certain kind of the external world by appeal to the presence in S of some other piece of knowledge of the very same kind. So there is an immediate problem if it is our aim to explain how any knowledge of the sort in question ever comes to be unless the explication is just beginning, and is to turn recursive in due course. Now of course A is theoretically ambitious, and in that respect the theorist who gives an answer of the form of A is doing something similar to what must be done by the protagonist in our car example, someone who is attempting to provide a general explanation of how any knowledge of a certain kind comes about. Nevertheless, there is also an important difference, namely that the theorist whose aim it is to give a general account of the form of A need not attribute any knowledge whatsoever to a subject S in explaining how that subject comes to have a piece of knowledge or justified belief. For there is no need to require that the conditions C appealed to by principle A must be conditions that include attribution of any knowledge at all to the subject in question. It is true that in claiming that A itself meets conditions C, and that it is this which explains how one knows A, we do perhaps take ourselves to know A or at least to be justified in believing it. But if so, this is the inevitable lot of anyone who seriously puts forward any explanation of anything. And it is quite different from a proposal that part of what explains how something is known or justifiably believed includes a claim to knowledge or justified belief of the very same sort. In sum, as in the case of one’s belief that one is awake, the belief in something of the form of A may be said to be known, and in so saying one does not commit oneself to adducing an ulterior reason in favor of A, or even to having such a reason in reserve. One is of course committed to being justified in believing A, perhaps even to having knowledge that A. But it is not at all clear that the only way to be justified in believing A is by way of adduced reasons in favor of A, or that one knows A only if one adduces strong enough reasons in its favor. For we often know things in the absence of such adduced reasons. Thus consider one’s knowledge through memory of which door one used to come into a room that has more than one open door. Returning finally to A, in its case the explanation of how one knows it may, once again, take the form of an appeal to the justifying power of intellectual virtues or of coherence  or both. Recent accounts of the nature of thought and representation undermine a tradition of wholesale doubt about nature, whose momentum is hard to stop, and threatens to leave the subject alone and restricted to a solipsism of the present moment. But there may be a way to stop skepticism early  by questioning the possibility of its being sensibly held, given what is required for meaningful language and thought. Consider our grasp of observable shape and color properties that objects around us might have. Such grasp seems partly constituted by our discriminatory abilities. When we discern a shape or a color we do so presumably in terms of a distinctive impact that such a shape or color has on us. We are put systematically into a certain distinctive state X when we are appropriately related, in good light, with our eyes open, etc., to the presence in our environment of that shape or color. What makes one’s distinctive state one of thinking of sphericity rather than something else, is said to be that it is a state tied by systematic causal relations to skepticism skepticism 849   849 the presence of sphericity in one’s normal environment. A light now flickers at the end of the skeptic’s tunnel. In doubt now is the coherence of traditional skeptical reflection. Indeed, our predecessors in earlier centuries may have moved in the wrong direction when they attempted a reduction of nature to the mind. For there is no way to make sense of one’s mind without its contents, and there is no way to make sense of how one’s mind can have such contents except by appeal to how one is causally related to one’s environment. If the very existence of that environment is put in doubt, that cuts the ground from under one’s ability reasonably to characterize one’s own mind, or to feel any confidence about its contents. Perhaps, then, one could not be a “brain in a vat.” Much contemporary thought about language and the requirements for meaningful language thus suggests that a lot of knowledge must already be in place for us to be able to think meaningfully about a surrounding reality, so as to be able to question its very existence. If so, then radical skepticism answers itself. For if we can so much as understand a radical skepticism about the existence of our surrounding reality, then we must already know a great deal about that reality.  Sceptics, those ancient thinkers who developed sets of arguments to show either that no knowledge is possible Academic Skepticism or that there is not sufficient or adequate evidence to tell if any knowledge is possible. If the latter is the case then these thinkers advocated suspending judgment on all question concerning knowledge Pyrrhonian Skepticism. Academic Skepticism gets its name from the fact that it was formulated in Plato’s Academy in the third century B.C., starting from Socrates’ statement, “All I know is that I know nothing.” It was developed by Arcesilaus c.268241 and Carneades c.213129, into a series of arguments, directed principally against the Stoics, purporting to show that nothing can be known. The Academics posed a series of problems to show that what we think we know by our senses may be unreliable, and that we cannot be sure about the reliability of our reasoning. We do not possess a guaranteed standard or criterion for ascertaining which of our judgments is true or false. Any purported knowledge claim contains some element that goes beyond immediate experience. If this claim constituted knowledge we would have to know something that could not possibly be false. The evidence for the claim would have to be based on our senses and our reason, both of which are to some degree unreliable. So the knowledge claim may be false or doubtful, and hence cannot constitute genuine knowledge. So, the Academics said that nothing is certain. The best we can attain is probable information. Carneades is supposed to have developed a form of verification theory and a kind of probabilism, similar in some ways to that of modern pragmatists and positivists. Academic Skepticism dominated the philosophizing of Plato’s Academy until the first century B.C. While Cicero was a student there, the Academy turned from Skepticism to a kind of eclectic philosophy. Its Skeptical arguments have been preserved in Cicero’s works, Academia and De natura deorum, in Augustine’s refutation in his Contra academicos, as well as in the summary presented by Diogenes Laertius in his lives of the Grecian philosophers. Skeptical thinking found another home in the school of the Pyrrhonian Skeptics, probably connected with the Methodic school of medicine in Alexandria. The Pyrrhonian movement traces its origins to Pyrrho of Elis c.360275 B.C. and his student Timon c.315225 B.C.. The stories about Pyrrho indicate that he was not a theoretician but a practical doubter who would not make any judgments that went beyond immediate experience. He is supposed to have refused to judge if what appeared to be chariots might strike him, and he was often rescued by his students because he would not make any commitments. His concerns were apparently ethical. He sought to avoid unhappiness that might result from accepting any value theory. If the theory was at all doubtful, accepting it might lead to mental anguish. The theoretical formulation of Pyrrhonian Skepticism is attributed to Aenesidemus c.100 40 B.C.. Pyrrhonists regarded dogmatic philosophers and Academic Skeptics as asserting too much, the former saying that something can be known and the latter that nothing can be known. The Pyrrhonists suspended judgments on all questions on which there was any conflicting evidence, including whether or not anything could be known. The Pyrrhonists used some of the same kinds of arguments developed by Arcesilaus and Carneades. Aenesidemus and those who followed after him organized the arguments into sets of “tropes” or ways of leading to suspense of judgment on various questions. Sets of ten, eight, five, and two tropes appear in the only surviving writing of the Pyrrhonists, the works of Sextus Empiricus, a third-century A.D. teacher of Pyrrhonism. Each set of tropes offers suggestions for suspending judgment about any knowledge claims that go beyond appearances. The tropes seek to show that for any claim, evidence for and evidence against it can be offered. The disagreements among human beings, the variety of human experiences, the fluctuation of human judgments under differing conditions, illness, drunkenness, etc., all point to the opposition of evidence for and against each knowledge claim. Any criterion we employ to sift and weigh the evidence can also be opposed by countercriterion claims. Given this situation, the Pyrrhonian Skeptics sought to avoid committing themselves concerning any kind of question. They would not even commit themselves as to whether the arguments they put forth were sound or not. For them Skepticism was not a statable theory, but rather an ability or mental attitude for opposing evidence for and against any knowledge claim that went beyond what was apparent, that dealt with the non-evident. This opposing produced an equipollence, a balancing of the opposing evidences, that would lead to suspending judgment on any question. Suspending judgment led to a state of mind called “ataraxia,” quietude, peace of mind, or unperturbedness. In such a state the Skeptic was no longer concerned or worried or disturbed about matters beyond appearances. The Pyrrhonians averred that Skepticism was a cure for a disease called “dogmatism” or rashness. The dogmatists made assertions about the non-evident, and then became disturbed about whether these assertions were true. The disturbance became a mental disease or disorder. The Pyrrhonians, who apparently were medical doctors, offered relief by showing the patient how and why he should suspend judgment instead of dogmatizing. Then the disease would disappear and the patient would be in a state of tranquillity, the peace of mind sought by Hellenistic dogmatic philosophers. The Pyrrhonists, unlike the Academic Skeptics, were not negative dogmatists. The Pyrrhonists said neither that knowledge is possible nor that it is impossible. They remained seekers, while allowing the Skeptical arguments and the equipollence of evidences to act as a purge of dogmatic assertions. The purge eliminates all dogmas as well as itself. After this the Pyrrhonist lives undogmatically, following natural inclinations, immediate experience, and the laws and customs of his society, without ever judging or committing himself to any view about them. In this state the Pyrrhonist would have no worries, and yet be able to function naturally and according to law and custom. The Pyrrhonian movement disappeared during the third century A.D., possibly because it was not considered an alternative to the powerful religious movements of the time. Only scant traces of it appear before the Renaissance, when the texts of Sextus and Cicero were rediscovered and used to formulate a modern skeptical view by such thinkers as Montaigne and Charron.  Refs.: The obvious source is the essay on scepticism in WoW, but there are allusions in “Prejudices and predilections, and elsewhere, in The H.

scheler: G. phenomenologist, social philosopher, and sociologist of knowledge. Born in Munich, he studied in Jena; when he returned to Munich in 7 he came in contact with phenomenology, especially the realist version of the early Husserl and his Munich School followers. Scheler’s first works were phenomenological studies in ethics leading to his ultimate theory of value: he described the moral feelings of sympathy and resentment and wrote a criticism of Kantian formalism and rationalism, Formalism in Ethics and a Non-Formal Ethics of Value 3. During the war, he was an ardent nationalist and wrote essays in support of the war that were also philosophical criticisms of modern culture, opposed to “Anglo-Saxon” naturalism and rational calculation. Although he later embraced a broader notion of community, such criticisms of modernity remained constant themes of his writings. His conversion to Catholicism after the war led him to apply phenomenological description to religious phenomena and feelings, and he later turned to themes of anthropology and natural science. The core of Scheler’s phenomenological method is his conception of the objectivity of essences, which, though contained in experience, are a priori and independent of the knower. For Scheler, values are such objective, though non-Platonic, essences. Their objectivity is intuitively accessible in immediate experience and feelings, as when we experience beauty in music and do not merely hear certain sounds. Scheler distinguished between valuations or value perspectives on the one hand, which are historically relative and variable, and values on the other, which are independent and invariant. There are four such values, the hierarchical organization of which could be both immediately intuited and established by various public criteria like duration and independence: pleasure, vitality, spirit, and religion. Corresponding to these values are various personalities who are not creators of value but their discoverers, historical disclosers, and exemplars: the “artist of consumption,” the hero, the genius, and the saint. A similar hierarchy of values applies to forms of society, the highest of which is the church, or a Christian community of solidarity and love. Scheler criticizes the leveling tendencies of liberalism for violating this hierarchy, leading to forms of resentment, individualism, and nationalism, all of which represent the false ordering of values.

schelling: G. philosopher whose metamorsphoses encompass the entire history of idealism. A Schwabian, Schelling studied at Tübingen, where he befriended Hölderlin and Hegel. Schelling was an enthusiastic exponent of Fichte’s Wissenschaftslehre and devoted several early essays to its exposition. After studying science and mathematics at Leipzig, he joins Fichte at Jena. Meanwhile, in such writings as Philosophische Briefe über Dogmatismus und Kritizismus Schelling betrays growing doubts concerning Fichte’s philosophy above all, its treatment of nature and a lively interest in Spinoza. He then turned to constructing a systematic Naturphilosophie within the context of which nature would be treated more holistically than by either Newtonian science or transcendental idealism. Of his many publications on this topic, two of the more important are Ideen zu einer Philosophie der Natur and Von der Weltseele. Whereas transcendental idealism attempts to derive objective experience from an initial act of free self-positing, Schelling’s philosophy of nature attempts to derive consciousness from objects. Beginning with “pure objectivity,” the Naturphilosophie purports to show how nature undergoes a process of unconscious self-development, culminating in the conditions for its own self-representation. The method of Naturphilosophie is fundamentally a priori: it begins with the concept of the unity of nature and accounts for its diversity by interpreting nature as a system of opposed forces or “polarities,” which manifest themselves in ever more complex levels of organization Potenzen. At Jena, Schelling came into contact with Tieck, Novalis, and the Schlegel brothers and became interested in art. This new interest is evident in his System des transzendentalen Idealismus 1800, which describes the path from pure subjectivity self-consciousness to objectivity the necessary positing of the Not-I, or of nature. The most innovative and influential portion of this treatise, which is otherwise closely modeled on Fichte’s Wissenschaftslehre, is its conclusion, which presents art as the concrete accomplishment of the philosophical task. In aesthetic experience the identity between the subjective and the objective, the ideal and the real, becomes an object to the experiencing I itself. For Schelling, transcendental idealism and Naturphilosophie are two complementary sides or subdivisions of a larger, more encompassing system, which he dubbed the System of Identity or Absolute Idealism and expounded in a series of publications, including the Darstellung meines Systems der Philosophie, Bruno  and Vorlesungen über die Methode des akademischen Studiums. The most distinctive feature of this system is that it begins with a bald assertion of the unity of thought and being, i.e., with the bare idea of the self-identical “Absolute,” which is described as the first presupposition of all knowledge. Since the identity with which this system commences transcends every conceivable difference, it is also described as the “point of indifference.” From this undifferentiated or “indifferent” starting point, Schelling proceeds to a description of reality as a whole, considered as a differentiated system within which unity is maintained by various synthetic relationships, such as substance and attribute, cause and effect, attraction and repulsion. Like his philosophy of nature, Schelling’s System of Identity utilizes the notion of various hierarchically related Potenzen as its basic organizing principle. The obvious question concerns the precise relationship between the “indifferent” Absolute and the real system of differentiated elements, a question that may be said to have set the agenda for Schelling’s subsequent philosophizing. Schelling was in Bavaria, where he continued to expound his System of Identity and to explore the philosophies of art and nature. The most distinctive feature of his thought during this period, however, was a new interest in religion and in the theosophical writings of Boehme, whose influence is prominent in the Philosophische Untersuchungen über das Wesen der menschlichen Freiheit “Philosophical Investigations concerning the Nature of Human Freedom,” 1809, a work often interpreted as anticipating existentialism. He also worked on a speculative interpretation of human history, Die Weltalter, which remained unpublished, and lectured regularly on the history of philosophy. Schelling moved to Berlin, where he lectured on his new philosophy of revelation and mythology, which he now characterized as “positive philosophy,” in contradistinction to the purely “negative” philosophy of Kant, Fichte, and Hegel. Some scholars have interpreted these posthumously published lectures as representing the culmination both of Schelling’s own protracted philosophical development and of G. idealism as a whole. 

schiller, G. philosopher. Signora Speranza’s favourite librettist for Verdi! -- Along with his colleagues Reinhold and Fichte, he participated in systematically revising Kant’s transcendental idealism. Though Schiller’s bestknown theoretical contributions were to aesthetics, his philosophical ambitions were more general, and he proposed a novel solution to the problem of the systematic unity, not merely of the critical philosophy, but of human nature. His most substantial philosophical work, Briefe über die äesthetische Erziehung des Menschen “Letters on the Aesthetic Education of Man,” 1794/95, examines the relationship between natural necessity and practical freedom and addresses two problems raised by Kant: How can a creature governed by natural necessity and desire ever become aware of its own freedom and thus capable of autonomous moral action? And how can these two sides of human nature  the natural, sensuous side and the rational, supersensuous one  be reconciled? In contradistinction both to those who subordinate principles to feelings “savages” and to those who insist that one should strive to subordinate feelings to principles “barbarians”, Schiller posited an intermediary realm between the sphere of nature and that of freedom, as well as a third basic human drive capable of mediating between sensuous and rational impulses. This third impulse is dubbed the “play impulse,” and the intermediary sphere to which it pertains is that of art and beauty. By cultivating the play impulse i.e., via “aesthetic education” one is not only freed from bondage to sensuality and granted a first glimpse of one’s practical freedom, but one also becomes capable of reconciling the rational and sensuous sides of one’s own nature. This idea of a condition in which opposites are simultaneously cancelled and preserved, as well as the specific project of reconciling freedom and necessity, profoundly influenced subsequent thinkers such as Schelling and Hegel and contributed to the development of G. idealism.

schlegel: Grice: “I’ve been reading Schlegel’s “On incomprehensibility,” in German, and found it surprisingly comprehensible!” -- G. philosopher, one of the principal representatives of G. Romanticism. In “On the Study of Grecian (or Griceian) Poetry Schlegel lays the foundations for the distinction between the classical and the romantic, e and a pronounced consciousness of literary modernity. Together with his brother August Wilhelm, he edited the Athenaeum,  the main theoretical organ of G. Romanticism, famous for its collection of fragments as a new means of critical communication. Schlegel is the originator of the Romantic theory of irony, a non-dialectical form of philosophizing and literary writing that takes its inspiration from Socratic irony and combines it with Fichte’s thought process of affirmation and negation, “self-creation” and “self-annihilation.” Closely connected wih Schlegel’s theory of irony is his theory of language and understanding hermeneutics. Critical reflection on language promotes an ironic awareness of the “necessity and impossibility of complete communication” Critical Fragments, No. 108; critical reflection on understanding reveals the amount of incomprehensibility, of “positive not-understanding” involved in every act of understanding On Incomprehensibility. Schlegel’s writings were essential for the rise of historical consciousness in G. Romanticism. His On Ancient and Modern Literature 1812 is reputed to represent the first literary history in a modern and broadly comparative fashion. His Philosophy of History, together with his Philosophy of Life and Philosophy of Language, confront Hegel’s philosophy from the point of view of a Christian and personalistic type of philosophizing. Schlegel converted to Catholicism in 1808. 

schleiermacher: G. philosopher, a “critical realist” working among post-Kantian idealists. In philosophy and science he presupposed transcendental features, noted in his dialectic lectures, and advocated integrative but historically contingent, empirical functions. Both develop, but, contra Hegel, not logically. Schleiermacher was a creator of modern general hermeneutics; a father of modern theological and religious studies; an advocate of women’s rights; the cofounder, with Humboldt, of the  at Berlin 180810, where he taught until 1834; and the classic translator of Plato into G.. Schleiermacher has had an undeservedly minor place in histories of philosophy. Appointed chiefly to theology, he published less philosophy, though he regularly lectured, in tightly argued discourse, in Grecian philosophy, history of philosophy, dialectic, hermeneutics and criticism, philosophy of mind “psychology”, ethics, politics, aesthetics, and philosophy of education. From the 0s, his collected writings and large correspondence began to appear in a forty-volume critical edition and in the larger Schleiermacher Studies and Translations series. Brilliant, newly available pieces from his twenties on freedom, the highest good, and values, previously known only in fragments but essential for understanding his views fully, were among the first to appear. Much of his outlook was formed before he became prominent in the early Romantic circle 17961806, distinguishable by his markedly religious, consistently liberal views.

schole – “The Grecian term for ‘otium.’” “Not to be confused with ‘studium’ as in ‘studium generale.’ Scholasticism, a set of scholarly and instructional techniques developed in Western European schools of the late medieval period, including the use of commentary and disputed question. ‘Scholasticism’ is derived from Latin scholasticus, which in the twelfth century meant the master of a school. The Scholastic method is usually presented as beginning in the law schools  notably at Bologna  and as being then transported into theology and philosophy by a series of masters including Abelard and Peter Lombard. Within the new universities of the thirteenth century the standardization of the curriculum and the enormous prestige of Aristotle’s work despite the suspicion with which it was initially greeted contributed to the entrenchment of the method and it was not until the educational reforms of the beginning of the sixteenth century that it ceased to be dominant. There is, strictly speaking, no such thing as Scholasticism. As the term was originally used it presupposed that a single philosophy was taught in the universities of late medieval Europe, but there was no such philosophy. The philosophical movements working outside the universities in the late sixteenth and early seventeenth centuries and the “neo-Scholastics” of the late nineteenth and early twentieth centuries all found such a presupposition useful, and their influence led scholars to assume it. At first this generated efforts to find a common core in the philosophies taught in the late medieval schools. More recently it has led to efforts to find methods characteristic of their teaching, and to an extension of the term to the schools of late antiquity and of Byzantium. Both among the opponents of the schools in the seventeenth century and among the “neoScholastics,” ‘Scholasticism’ was supposed to designate a doctrine whose core was the doctrine of substance and accidents. As portrayed by Descartes and Locke, the Scholastics accepted the view that among the components of a thing were a substantial form and a number of real accidental forms, many of which corresponded to perceptible properties of the thing  its color, shape, temperature. They were also supposed to have accepted a sharp distinction between natural and unnatural motion. 

schopenhauer: philosopher born in Danzig and schooled in G.y, France, and England during a welltraveled childhood, he became acquainted through his novelist mother with Goethe, Schlegel, and the brothers Grimm. He studied medicine at the  of Göttingen and philosophy at Berlin; received the doctorate from the  of Jena; and lived much of his adult life in Frankfurt, where he died. Schopenhauer’s dissertation, On the Fourfold Root of the Principle of Sufficient Reason lays the groundwork for all of his later philosophical work. The world of representation equivalent to Kant’s phenomenal world is governed by “the principle of sufficient reason.” “Every possible object  stands in a necessary relation to other objects, on the one hand as determined, on the other as determining” The World as Will and Representation. Thus, each object of consciousness can be explained in terms of its relations with other objects. The systematic statement of Schopenhauer’s philosophy appeared in The World as Will and Representation. His other works are On Vision and Colors,” “On the Will in Nature” conjoined with “On the Foundation of Morality” in The Two Fundamental Problems of Ethics. The second edition of The World as Will and Representation, which included a second volume of essays; an enlarged and revised edition of On the Fourfold Root of the Principle of Sufficient Reason; and Parerga and Paralipomena, a series of essays 1851. These are all consistent with the principal statement of his thought in The World as Will and Representation. The central postulate of Schopenhauer’s system is that the fundamental reality is will, which he equates with the Kantian thing-in-itself. Unlike Kant, Schopenhauer contends that one can immediately know the thing-in-itself through the experience of an inner, volitional reality within one’s own body. Every phenomenon, according to Schopenhauer, has a comparable inner reality. Consequently, ‘will’ can extend to the inner nature of all things. Moreover, because number pertains exclusively to the phenomenal world, the will, as thing-initself, is ONE. Nevertheless, different types of things manifest the will to different degrees. Schopenhauer accounts for these differences by invoking Plato’s Ideas or Forms. The Ideas are the universal prototypes for the various kinds of objects in the phenomenal world. Taken collectively, the Ideas constitute a hierarchy. We usually overlook them in everyday experience, focusing instead on particulars and their practical relationships to us. However, during aesthetic experience, we recognize the universal Idea within the particular; simultaneously, as aesthetic beholders, we become “the universal subject of knowledge.” Aesthetic experience also quiets the will within us. The complete silencing of the will is, for Schopenhauer, the ideal for human beings, though it is rarely attained. Because will is the fundamental metaphysical principle, our lives are dominated by willing  and, consequently, filled with struggle, conflict, and dissatisfaction. Schopenhauer contends that all of life is suffering, which only an end to desire can permanently eliminate as opposed to the respite of aesthetic experience. This is achieved only by the saint, who rejects desire in an inner act, a denial of the will to live. The saint fully grasps that the same will motivates all phenomena and, recognizing that nothing is gained through struggle and competition, achieves “resignation.” Such a person achieves the ethical ideal of all religions compassion toward all beings, resulting from the insight that all are, fundamentally, one.

schröder’s and bernstein’s theorem: “One of my favourite theorems.” – Grice. the theorem that mutually dominant sets are equinumerous. A set A is said to be dominated by a set B if and only if each element of A can be mapped to a unique element of B in such a way that no two elements of A are mapped to the same element of B possibly with some elements of B left over. Intuitively, if A is dominated by B, then B has at least as many members as A. Given this intuition, one would expect that if A is dominated by B and B is dominated by A, then A and B are equinumerous i.e., A can be mapped to B as described above with no elements of B left over. This is the Schröder-Bernstein theorem. Stated in terms of cardinal numbers, the theorem says that if k m l and l m k, then k % l. Despite the simplicity of the theorem’s statement, its proof is non-trivial, “but quadrivial.”

schrödinger: philosopher best known for five papers published in 6, in which he discovered the Schrödinger wave equation and created modern wave mechanics. For this achievement, he was awarded the Nobel prize in physics shared with Paul Dirac in 3. Like Einstein, Schrödinger was a resolute but ultimately unsuccessful critic of the Copenhagen interpretation of quantum mechanics. Schrödinger defended the view which he derived from Boltzmann that theories should give a picture, continuous in space and time, of the real processes that produce observable phenomena. Schrödinger’s realistic philosophy of science played an important role in his discovery of wave mechanics. Although his physical interpretation of the psi function was soon abandoned, his approach to quantum mechanics survives in the theories of Louis de Broglie and David Bohm. 

schulze: G. philosopher known mainly as an acute and influential early critic of Kant and Reinhold. He taught at Wittenberg, Helmstedt, and Göttingen; one of his most important students was Schopenhauer, whose view of Kant was definitely influenced by Schulze’s interpretation. Schulze’s most important work was his Aenesidemus, or “On the Elementary Philosophy Put Forward by Mr. Reinhold in Jena. Together with a Defense of Skepticism” 1792. It fundamentally changed the discussion of Kantian philosophy. Kant’s earliest critics had accused him of being a skeptic like Hume. Kantians, like Reinhold, had argued that critical philosophy was not only opposed to skepticism, but also contained the only possible refutation of skepticism. Schulze tried to show that Kantianism could not refute skepticism, construed as the doctrine that doubts the possibility of any knowledge concerning the existence or non-existence of “things-in-themselves,” and he argued that Kant and his followers begged the skeptic’s question by presupposing that such things exist and causally interact with us. Schulze’s Aenesidemus had a great impact on Fichte and Hegel, and it also influenced neoKantianism.

scire – sapio -- sapientia: wisdom, an understanding of the highest principles of things that functions as a guide for living a truly exemplary human life. From the preSocratics through Plato this was a unified notion. But Aristotle introduced a distinction between theoretical wisdom sophia and practical wisdom phronesis, the former being the intellectual virtue that disposed one to grasp the nature of reality in terms of its ultimate causes metaphysics, the latter being the ultimate practical virtue that disposed one to make sound judgments bearing on the conduct of life. The former invoked a contrast between deep understanding versus wide information, whereas the latter invoked a contrast between sound judgment and mere technical facility. This distinction between theoretical and practical wisdom persisted through the Middle Ages and continues to our own day, as is evident in our use of the term ‘wisdom’ to designate both knowledge of the highest kind and the capacity for sound judgment in matters of conduct. Grice: “The etymology of ‘sapientia’ is excellent – it’s like taste!” –  săpĭo , īvi or ĭi (sapui, Aug. Civ. Dei, 1, 10; id. Ep. 102, 10; but sapivi, Nov. ap. Prisc. p. 879 P.; id. ap.

res: reale: Grice: “Possibly the philosophically most important Roman neuter expression,” -- is res! "Unfortunately, the etymology is dubious." "Perhaps "res" comes from a root ra- of reor, ratus."- to reckon, calculate, believe, think, suppose, imagine, judge, deem, as in English 'ratify,' and 'reason.'  "I am reminded of German "ding;" English "thing," from "denken," to think; prop., that which is thought of." "I am also reminded of "λόγος," Lid. and Scott, 9, a thing, object, being; a matter, affair, event, fact, circumstance, occurrence, deed, condition, case, etc.; and sometimes merely = something (cf.: causa, ratio, negotium)." realism, the view that the subject matter of common sense or scientific research and scientific theories exists independently of our knowledge of it, and that the goal of science is the description and explanation of both observable and unobservable aspects of the world. Scientific realism is contrasted with logical empiricism and social constructivism. Early arguments for scientific realism simply stated that, in light of the impressive products and methods of science, realism is the only philosophy that does not make the success of science a miracle. Formulations of scientific realism focus on the objects of theoretical knowledge: theories, laws, and entities. One especially robust argument for scientific realism due to Putnam and Richard Boyd is that the instrumental reliability of scientific methodology in the mature sciences such as physics, chemistry, and some areas of biology can be explained adequately only if we suppose that theories in the mature sciences are at least approximately true and their central theoretical terms are at least partially referential Putnam no longer holds this view. More timid versions of scientific realism do not infer approximate truth of mature theories. For example, Ian Hacking’s “entity realism” 3 asserts that the instrumental manipulation of postulated entities to produce further effects gives us legitimate grounds for ontological commitment to theoretical entities, but not to laws or theories. Paul Humphreys’s “austere realism” 9 states that only theoretical commitment to unobserved structures or dispositions could explain the stability of observed outcomes of scientific inquiry. Distinctive versions of scientific realism can be found in works by Richard Boyd 3, Philip Kitcher 3, Richard Miller 7, William Newton-Smith 1, and J. D. Trout 8. Despite their differences, all of these versions of realism are distinguished  against logical empiricism  by their commitment that knowledge of unobservable phenomena is not only possible but actual. As well, all of the arguments for scientific realism are abductive; they argue that either the approximate truth of background theories or the existence of theoretical entities and laws provides the best explanation for some significant fact about the scientific theory or practice. Scientific realists address the difference between real entities and merely useful constructs, arguing that realism offers a better explanation for the success of science. In addition, scientific realism recruits evidence from the history and practice of science, and offers explanations for the success of science that are designed to honor the dynamic and uneven character of that evidence. Most arguments for scientific realism cohabit with versions of naturalism. Anti-realist opponents argue that the realist move from instrumental reliability to truth is question-begging. However, realists reply that such formal criticisms are irrelevant; the structure of explanationist arguments is inductive and their principles are a posteriori. 

applicatum, extensum -- extensio: scope, the “part” of the sentence or proposition to which a given term “applies” under a given interpretation of the sentence. If the sentence ‘Abe does not believe Ben died’ is interpreted as expressing the proposition that Abe believes that it is not the case that Ben died, the scope of ‘not’ is ‘Ben died’; interpreted as “It is not the case that Abe believes that Ben died,” the scope is the rest of the sentence, i.e., ‘Abe believes Ben died’. In the first case we have narrow scope, in the second wide scope. If ‘Every number is not even’ is interpreted with narrow scope, it expresses the false proposition that every number is non-even, which is logically equivalent to the proposition that no number is even. Taken with wide scope it expresses the truth that not every number is even, which is equivalent to the truth that some number is non-even. Under normal interpretations of the sentences, ‘hardened’ has narrow scope in ‘Carl is a hardened recidivist’, whereas ‘alleged’ has wide scope in ‘Dan is an alleged criminal’. Accordingly, ‘Carl is a hardened recidivist’ logically implies ‘Carl is a recidivist’, whereas ‘Dan is an alleged criminal’, being equivalent to ‘Allegedly, Dan is a criminal’, does not imply ‘Dan is a criminal’. Scope considerations are useful in analyzing structural ambiguity and in understanding the difference between the grammatical form of a sentence and the logical form of a proposition it expresses. In a logically perfect language grammatical form mirrors logical form, there is no scope ambiguity, and the scope of a given term is uniquely determined by its context. 

scots common sense philosophy, a comprehensive philosophical position developed by Reid in the latter part of the eighteenth century. Reid’s views were propagated by a succession of Scottish popularizers, of whom the most successful was Dugald Stewart. Through them common sense doctrine became nearly a philosophical orthodoxy in Great Britain during the first half of the nineteenth century. Brought to the United States through the s in Princeton and Philadelphia, common sensism continued to be widely taught until the later nineteenth century. The early Reidians Beattie and Oswald were, like Reid himself, read in G.y by Kant and others; and Reid’s views were widely taught in post-Napoleonic France. The archenemy for the common sense theorists was Hume. Reid saw in his skepticism the inevitable outcome of Descartes’s thesis, accepted by Locke, that we do not perceive external objects directly, but that the immediate object of perception is something in the mind. Against this he argued that perception involves both sensation and certain intuitively known general truths or principles that together yield knowledge of external objects. He also argued that there are many other intuitively known general principles, including moral principles, available to all normal humans. As a result he thought that whenever philosophical argument results in conclusions that run counter to common sense, the philosophy must be wrong. Stewart made some changes in Reid’s acute and original theory, but his main achievement was to propagate it through eloquent classes and widely used textbooks. Common sensism, defending the considered views of the ordinary man, was taken by many to provide a defense of the Christian religious and moral status quo. Reid had argued for free will, and presented a long list of self-evident moral axioms. If this might be plausibly presented as part of the common sense of his time, the same could not be said for some of the religious doctrines that Oswald thought equally self-evident. Reid had not given any rigorous tests for what might count as selfevident. The easy intuitionism of later common sensists was a natural target for those who, like J. S. Mill, thought that any appeal to self-evidence was simply a way of justifying vested interest. Whewell, in both his philosophy of science and his ethics, and Sidgwick, in his moral theory, acknowledged debts to Reid and tried to eliminate the abuses to which his method was open. But in doing so they transformed common sensism beyond the limits within which Reid and those shaped by him operated.

searleim, or “playing for the gallery,” as Grice calls it – after Oxonian Rhodes scholar philosopher of language and mind D. Phil., Oxford influenced by Frege, Vitters, and J. L. Austin; a founder of speech act theory and an important contributor to debates on intentionality, consciousness, and institutional facts. Language. In Speech Acts: An Essay in the Philosophy of Language 9, Searle brings together modified versions of Frege’s distinctions between the force F and content P of a sentence, and between singular reference and predication, Austin’s analysis of speech acts, and Grice’s analysis of speaker meaning. Searle explores the hypothesis that the semantics of a natural language can be regarded as a conventional realization of underlying constitutive rules and that illocutionary acts are acts performed in accordance with these rules. Expression and Meaning 9 extends this analysis to non-literal and indirect illocutionary acts, and attempts to explain Donnellan’s referential-attributive distinction in these terms and proposes an influential taxonomy of five basic types of illocutionary acts based on the illocutionary point or purpose of the act, and word-to-world versus world-toword direction of fit. Language and mind. Intentionality: An Essay in the Philosophy of Mind 3 forms the foundation for the earlier work on speech acts. Now the semantics of a natural language is seen as the result of the mind intrinsic intentionality imposing conditions of satisfaction or aboutness on objects expressions in a language, which have intentionality only derivatively. Perception and action rather than belief are taken as fundamental. Satisfaction conditions are essentially Fregean i.e. general versus singular and internal  meaning is in the head, relative to a background of non-intentional states, and relative to a network of other intentional states. The philosophy of language becomes a branch of the philosophy of mind. Mind. “Minds, Brains and Programs” 0 introduced the famous “Chin. room” argument against strong artificial intelligence  the view that appropriately programming a machine is sufficient for giving it intentional states. Suppose a monolingual English-speaker is working in a room producing Chin. answers to Chin. questions well enough to mimic a Chin.speaker, but by following an algorithm written in English. Such a person does not understand Chin. nor would a computer computing the same algorithm. This is true for any such algorithms because they are syntactically individuated and intentional states are semantically individuated. The Rediscovery of the Mind 2 continues the attack on the thesis that the brain is a digital computer, and develops a non-reductive “biological naturalism” on which intentionality, like the liquidity of water, is a high-level feature, which is caused by and realized in the brain. Society. The Construction of Social Reality 5 develops his realistic worldview, starting with an independent world of particles and forces, up through evolutionary biological systems capable of consciousness and intentionality, to institutions and social facts, which are created when persons impose status-features on things, which are collectively recognized and accepted.  Refs.: H.

first-order predicate calculus with time-relative identity: - second-order logic, the logic of languages that contain, in addition to variables ranging over objects, variables ranging over properties, relations, functions, or classes of those objects. A model, or interpretation, of a formal language usually contains a domain of discourse. This domain is what the language is about, in the model in question. Variables that range over this domain are called first-order variables. If the language contains only first-order variables, it is called a first-order language, and it is within the purview of first-order logic. Some languages also contain variables that range over properties, relations, functions, or classes of members of the domain of discourse. These are second-order variables. A language that contains first-order and second-order variables, and no others, is a secondorder language. The sentence ‘There is a property shared by all and only prime numbers’ is straightforwardly rendered in a second-order language, because of the bound variable ranging over properties. There are also properties of properties, relations of properties, and the like. Consider, e.g., the property of properties expressed by ‘P has an infinite extension’ or the relation expressed by ‘P has a smaller extension than Q’. A language with variables ranging over such items is called thirdorder. This construction can be continued, producing fourth-order languages, etc. A language is called higher-order if it is at least second-order. Deductive systems for second-order languages are obtained from those for first-order languages by adding straightforward extensions of the axioms and rules concerning quantifiers that bind first-order variables. There may also be an axiom scheme of comprehension: DPExPx S Fx, one instance for each formula F that does not contain P free. The scheme “asserts” that every formula determines the extension of a property. If the language has variables ranging over functions, there may also be a version of the axiom of choice: ERExDyRxy P DfExRxfx. In standard semantics for second-order logic, a model of a given language is the same as a model for the corresponding first-order language. The relation variables range over every relation over the domain-of-discourse, the function variables range over every function from the domain to the domain, etc. In non-standard, or Henkin semantics, each model consists of a domain-ofdiscourse and a specified collection of relations, functions, etc., on the domain. The latter may not include every relation or function. The specified collections are the range of the second-order variables in the model in question. In effect, Henkin semantics regards second-order languages as multi-sorted, first-order languages. 

secundum quid: in a certain respect, or with a qualification. Fallacies can arise from confusing what is true only secundum quid with what is true simpliciter ‘without qualification’, ‘absolutely’, ‘on the whole’, or conversely. Thus a strawberry is red simpliciter on the whole. But it is black, not red, with respect to its seeds, secundum quid. By ignoring the distinction, one might mistakenly infer that the strawberry is both red and not red. Again, a certain thief is a good cook, secundum quid; but it does not follow that he is good simpliciter without qualification. Aristotle was the first to recognize the fallacy secundum quid et simpliciter explicitly, in his Sophistical Refutations. On the basis of some exceptionally enigmatic remarks in the same work, the liar paradox was often regarded in the Middle Ages as an instance of this fallacy. 

deceptum sui: Auto-deception – D. F. Pears -- self-deception, 1 purposeful action to avoid unpleasant truths and painful topics about oneself or the world; 2 unintentional processes of denial, avoidance, or biased perception; 3 mental states resulting from such action or processes, such as ignorance, false belief, wishful thinking, unjustified opinions, or lack of clear awareness. Thus, parents tend to exaggerate the virtues of their children; lovers disregard clear signs of unreciprocated affection; overeaters rationalize away the need to diet; patients dying of cancer pretend to themselves that their health is improving. In some contexts ‘self-deception’ is neutral and implies no criticism. Deceiving oneself can even be desirable, generating a vital lie that promotes happiness or the ability to cope with difficulties. In other contexts ‘self-deception’ has negative connotations, suggesting bad faith, false consciousness, or what Joseph Butler called “inner hypocrisy”  the refusal to acknowledge our wrongdoing, character flaws, or onerous responsibilities. Existentialist philosophers, like Kierkegaard, Heidegger, and most notably Sartre Being and Nothingness, 3, denounced self-deception as an inauthentic dishonest, cowardly refusal to confront painful though significant truths, especially about freedom, responsibility, and death. Herbert Fingarette, however, argued that self-deception is morally ambiguous  neither clearly blameworthy nor clearly faultless  because of how it erodes capacities for acting rationally Self-Deception, 9. The idea of intentionally deceiving oneself seems paradoxical. In deceiving other people I usually know a truth that guides me as I state the opposite falsehood, intending thereby to mislead them into believing the falsehood. Five difficulties seem to prevent me from doing anything like that to myself. 1 With interpersonal deception, one person knows something that another person does not. Yet self-deceivers know the truth all along, and so it seems they cannot use it to make themselves ignorant. One solution is that self-deception occurs over time, with the initial knowledge becoming gradually eroded. Or perhaps selfdeceivers only suspect rather than know the truth, and then disregard relevant evidence. 2 If consciousness implies awareness of one’s own conscious acts, then a conscious intention to deceive myself would be self-defeating, for I would remain conscious of the truth I wish to flee. Sartre’s solution was to view self-deception as spontaneous and not explicitly reflected upon. Freud’s solution was to conceive of self-deception as unconscious repression. 3 It seems that self-deceivers believe a truth that they simultaneously get themselves not to believe, but how is that possible? Perhaps they keep one of two conflicting beliefs unconscious or not fully conscious. 4 Self-deception suggests willfully creating beliefs, but that seems impossible since beliefs cannot voluntarily be chosen. Perhaps beliefs can be indirectly manipulated by selectively ignoring and attending to evidence. 5 It seems that one part of a person the deceiver manipulates another part the victim, but such extreme splits suggest multiple personality disorders rather than self-deception. Perhaps we are composed of “subselves”  relatively unified clusters of elements in the personality. Or perhaps at this point we should jettison interpersonal deception as a model for understanding self-deception.  .

determinatum sui: auto-determination -- self-determination, the autonomy possessed by a community when it is politically independent; in a strict sense, territorial sovereignty. Within international law, the principle of self-determination appears to grant every people a right to be self-determining, but there is controversy over its interpretation. Applied to established states, the principle calls for recognition of state sovereignty and non-intervention in internal affairs. By providing for the self-determination of subordinate communities, however, it can generate demands for secession that conflict with existing claims of sovereignty. Also, what non-self-governing groups qualify as beneficiaries? The national interpretation of the principle treats cultural or national units as the proper claimants, whereas the regional interpretation confers the right of self-determination upon the populations of well-defined regions regardless of cultural or national affiliations. This difference reflects the roots of the principle in the doctrines of nationalism and popular sovereignty, respectively, but complicates its application. 

evidens sui: (after ‘causa sui’), self-evidence, the property of being self-evident. Only true propositions or truths are self-evident, though false propositions can appear to be self-evident. It is widely held that a true proposition is self-evident if and only if one would be justified in believing it if one adequately understood it. Some would also require that self-evident propositions are known if believed on the basis of such an understanding. Some self-evident propositions are obvious, such as the proposition that all stags are male, but others are not, since it may take considerable reflection to achieve an adequate understanding of them. That slavery is wrong and that there is no knowledge of falsehoods are perhaps examples of the latter. Not all obvious propositions are self-evident, e.g., it is obvious that a stone will fall if dropped, but adequate understanding of that claim does not by itself justify one in believing it. An obvious proposition is one that immediately seems true for anyone who adequately understands it, but its obviousness may rest on wellknown and commonly accepted empirical facts, not on understanding. All analytic propositions are self-evident but not all self-evident propositions are analytic. The propositions that if A is older than B, then B is younger than A, and that no object can be red and green all over at the same time and in the same respects, are arguably self-evident but not analytic. All self-evident propositions are necessary, for one could not be justified in believing a contingent proposition simply in virtue of understanding it. However, not all necessary propositions are self-evident, e.g., that water is H2O and that temperature is the measure of the molecular activity in substances are necessary but not self-evident. A proposition can appear to be selfevident even though it is not. For instance, the proposition that all unmarried adult males are bachelors will appear self-evident to many until they consider that the pope is such a male. A proposition may appear self-evident to some but not to others, even though it must either have or lack the property of being self-evident. Self-evident propositions are knowable non-empirically, or a priori, but some propositions knowable a priori are not self-evident, e.g., certain conclusions of long and difficult chains of mathematical reasoning. 

auto-present: self-presenting, in the philosophy of Meinong, having the ability  common to all mental states  to be immediately present to our thought. “Meinong was too German to be English – take ‘wahrnehmen,’ to perceive, to take notice, to ‘verum’-sit.!” Warhnehmungvorstellung is perceptual representation – Chisholm, alas, never gives, typically in a second-tier varsity, to give the correct citation, when he claims, to impress, that he is ‘borrowing’ from Meinong, never to return! (“also typical of a second-tier!” -- Grice). In Meinong’s view, no mental state can be presented to our thought in any other way  e.g., indirectly, via a Lockean “idea of reflection.” The only way to apprehend a mental state is to experience or “live through” it. The experience involved in the apprehension of an external object has thus a double presentational function: 1 via its “content” it presents the object to our thought; 2 as its own “quasi-content” it presents itself immediately to our thought. In the contemporary era, Roderick Chisholm has based his account of empirical knowledge in part on a related concept of the self-presenting. In Chisholm’s sense  the definition of which we omit here  all self-presenting states are mental, but not conversely; for instance, being depressed because of the death of one’s spouse would not be self-presenting. In Chisholm’s epistemology, self-presenting states are a source of certainty in the following way: if F is a self-presenting state, then to be certain that one is in state F it is sufficient that one is, and believes oneself to be in state F. Cf. untranslatable, ‘sui,’ ‘ipse,’ ‘idem’. Presentatum de se.

self-reproducing automaton: a formal model of self-reproduction of a kind introduced by von Neumann. He worked with an intuitive robot model and then with a well-defined cellular automaton model. Imagine a class of robotic automata made of robot parts and operating in an environment of such parts. There are computer parts switches, memory elements, wires, input-output parts sensing elements, display elements, action parts grasping and moving elements, joining and cutting elements, and straight bars to maintain structure and to employ in a storage tape. There are also energy sources that enable the robots to operate and move around. These five categories of parts are sufficient for the construction of robots that can make objects of various kinds, including other robots. These parts also clearly suffice for making a robot version of any finite automaton. Sensing and acting parts can then be added to this robot so that it can make an indefinitely expandable storage tape from straight bars. A “blank tape” consists of bars joined in sequence, and the robot stores information on this tape by attaching bars or not at the junctions. If its finite automaton part can execute programs and is sufficiently powerful, such a robot is a universal computing robot cf. a universal Turing machine. A universal computing robot can be augmented to form a universal constructing robot  a robot that can construct any robot, given its description. Let r be any robot with an indefinitely expandable tape, let Fr be the description of its finite part, and let Tr be the information on its tape. Now take a universal computing robot and augment it with sensing and acting devices and with programs so that when Fr followed by Tr is written on its tape, this augmented universal computer performs as follows. First, it reads the description Fr, finds the needed parts, and constructs the finite part of r. Second, it makes a blank tape, attaches it to the finite part of r, and then copies the information Tr from its own tape onto the new tape. This augmentation of a universal computing robot is a universal constructor. For when it starts with the information Fr,Tr written on its tape, it will construct a copy of r with Tr on its tape. Robot self-reproduction results from applying the universal constructor to itself. Modify the universal constructor slightly so that when only a description Fr is written on its tape, it constructs the finite part of r and then attaches a tape with Fr written on it. Call this version of the universal constructor Cu. Now place Cu’s description FCu on its own tape and start it up. Cu first reads this description and constructs a copy of the finite part of itself in an empty region of the cellular space. Then it adds a blank tape to the new construction and copies FCu onto it. Hence Cu with FCu on its tape has produced another copy of Cu with FCu on its tape. This is automaton self-reproduction. This robot model of self-reproduction is very general. To develop the logic of self-reproduction further, von Neumann first extended the concept of a finite automaton to that of an infinite cellular automaton consisting of an array or “space” of cells, each cell containing the same finite automaton. He chose an infinite checkerboard array for modeling self-reproduction, and he specified a particular twenty-nine-state automaton for each square cell. Each automaton is connected directly to its four contiguous neighbors, and communication between neighbors takes one or two time-steps. The twenty-nine states of a cell fall into three categories. There is a blank state to represent the passivity of an empty area. There are twelve states for switching, storage, and communication, from which any finite automaton can be constructed in a sufficiently large region of cells. And there are sixteen states for simulating the activities of construction and destruction. Von Neumann chose these twenty-nine states in such a way that an area of non-blank cells could compute and grow, i.e., activate a path of cells out to a blank region and convert the cells of that region into a cellular automaton. A specific cellular automaton is embedded in this space by the selection of the initial states of a finite area of cells, all other cells being left blank. A universal computer consists of a sufficiently powerful finite automaton with a tape. The tape is an indefinitely long row of cells in which bits are represented by two different cell states. The finite automaton accesses these cells by means of a construction arm that it extends back and forth in rows of cells contiguous to the tape. When activated, this finite automaton will execute programs stored on its tape. A universal constructor results from augmenting the universal computer cf. the robot model. Another construction arm is added, together with a finite automaton controller to operate it. The controller sends signals into the arm to extend it out to a blank region of the cellular space, to move around that region, and to change the states of cells in that region. After the universal constructor has converted the region into a cellular automaton, it directs the construction arm to activate the new automaton and then withdraw from it. Cellular automaton selfreproduction results from applying the universal constructor to itself, as in the robot model. Cellular automata are now studied extensively by humans working interactively with computers as abstract models of both physical and organic systems. See Arthur W. Burks, “Von Neumann’s Self-Reproducing Automata,” in Papers of John von Neumann on Computers and Computer Theory, edited by William Aspray and Arthur Burks, 7. The study of artificial life is an outgrowth of computer simulations of cellular automata and related automata. Cellular automata organizations are sometimes used in highly parallel computers. 

sellars: philosopher, son of Roy Wood Sellars, and one of the great systematic New-World (“as opposed to the Old World to which I belong” – Grice)  philosophers of the century. His most influential and representative works are “Empiricism and the Philosophy of Mind” 6 and “Philosophy and the Scientific Image of Man” 0. The Sellarsian system may be outlined as follows. The myth of the given. Thesis 1: Classical empiricism foundationalism maintains that our belief in the commonsense, objective world of physical objects is ultimately justified only by the way that world presents itself in sense experience. Thesis 2: It also typically maintains that sense experience a is not part of that world and b is not a form of conceptual cognition like thinking or believing. Thesis 3: From 1 and 2a classical empiricism concludes that our knowledge of the physical world is inferred from sense experience. Thesis 4: Since inferences derive knowledge from knowledge, sense experience itself must be a form of knowledge. Theses 14 collectively are the doctrine of the given. Each thesis taken individually is plausible. However, Sellars argues that 2b and 4 are incompatible if, as he thinks, knowledge is a kind of conceptual cognition. Concluding that the doctrine of the given is false, he maintains that classical empiricism is a myth. The positive system. From an analysis of theoretical explanation in the physical sciences, Sellars concludes that postulating theoretical entities is justified only if theoretical laws  nomological generalizations referring to theoretical entities  are needed to explain particular observable phenomena for which explanation in terms of exceptionless observation laws is unavailable. While rejecting any classical empiricist interpretation of observation, Sellars agrees that some account of non-inferential knowledge is required to make sense of theoretical explanation thus conceived. He thinks that utterances made in direct response to sensory stimuli observational reports count as non-inferential knowledge when a they possess authority, i.e., occur in conditions ensuring that they reliably indicate some physical property say, shape in the environment and are accepted by the linguistic community as possessing this quality; and b the utterer has justified belief that they possess this authority. Sellars claims that some perceptual conditions induce ordinary people to make observation reports inconsistent with established explanatory principles of the commonsense framework. We thus might tend to report spontaneously that an object is green seen in daylight and blue seen indoors, and yet think it has not undergone any process that could change its color. Sellars sees in such conflicting tendencies vestiges of a primitive conceptual framework whose tensions have been partially resolved by introducing the concept of sense experiences. These experiences count as theoretical entities, since they are postulated to account for observational phenomena for which no exceptionless observation laws exist. This example may serve as a paradigm for a process of theoretical explanation occurring in the framework of commonsense beliefs that Sellars calls the manifest image, a process that itself is a model for his theory of the rational dynamics of conceptual change in both the manifest image and in science  the scientific image. Because the actual process of conceptual evolution in Homo sapiens may not fit this pattern of rational dynamics, Sellars treats these dynamics as occurring within certain hypothetical ideal histories myths of the way in which, from certain conceptually primitive beginnings, one might have come to postulate the requisite theoretical explanations. The manifest image, like the proto-theories from which it arose, is itself subject to various tensions ultimately resolved in the scientific image. Because this latter image contains a metaphysical theory of material objects and persons that is inconsistent with that of its predecessor framework, Sellars regards the manifest image as replaced by its successor. In terms of the Peircean conception of truth that Sellars endorses, the scientific image is the only true image. In this sense Sellars is a scientific realist. There is, however, also an important sense in which Sellars is not a scientific realist: despite discrediting classical empiricism, he thinks that the intrinsic nature of sense experience gives to conceptualization more than simply sensory stimulus yet less than the content of knowledge claims. Inspired by Kant, Sellars treats the manifest image as a Kantian phenomenal world, a world that exists as a cognitive construction which, though lacking ideal factual truth, is guided in part by intrinsic features of sense experience. This is not analytic phenomenalism, which Sellars rejects. Moreover, the special methodological role for sense experience has effects even within the scientific image itself. Theories of mind, perception, and semantics. Mind: In the manifest image thoughts are private episodes endowed with intentionality. Called inner speech, they are theoretical entities whose causal and intentional properties are modeled, respectively, on inferential and semantic properties of overt speech. They are introduced within a behaviorist proto-theory, the Rylean framework, to provide a theoretical explanation for behavior normally accompanied by linguistically overt reasons. Perception: In the manifest image sense experiences are sense impressions  states of persons modeled on two-dimensional, colored physical replicas and introduced in the theoretical language of the adverbial theory of perception to explain why it can look as if some perceptible quality is present when it is not. Semantics: The meaning of a simple predicate p in a language L is the role played in L by p defined in terms of three sets of linguistic rules: language entry rules, intralinguistic rules, and language departure rules. This account also supports a nominalist treatment of abstract entities. Identification of a role for a token of p in L can be effected demonstratively in the speaker’s language by saying that p in L is a member of the class of predicates playing the same role as a demonstrated predicate. Thus a speaker of English might say that ‘rot’ in G. plays the semantic role ‘red’ has in English. Sellars sees science and metaphysics as autonomous strands in a single web of philosophical inquiry. Sellarsianism thus presents an important alternative to the view that what is fundamentally real is determined by the logical structure of scientific language alone. Sellars also sees ordinary language as expressing a commonsense framework of beliefs constituting a kind of proto-theory with its own methods, metaphysics, and theoretical entities. Thus, he also presents an important alternative to the view that philosophy concerns not what is ultimately real, but what words like ‘real’ ultimately mean in ordinary language. 

semantic: semantic – Grice saw ‘semantics’ (he detested the pretentious ‘pragmatics’) as a branch of philosophy. “Surely we cannot expect someone whose training includes phonetics, a totally physical science, to have any saying on the nuances of the communicatum, which is all semantics is about!” -- H. P. Grice, “Logic and conversation” – “Meaning,” in P. F. Strawson, “Philosophical Logic,” Oxford -- the arena of philosophy devoted to examining the scope and nature of logic. Aristotle considered logic an organon, or foundation, of knowledge. Certainly, inference is the source of much human knowledge. Logic judges inferences good or bad and tries to justify those that are good. One need not agree with Aristotle, therefore, to see logic as essential to epistemology. Philosophers such as Vitters, additionally, have held that the structure of language reflects the structure of the world. Because inferences have elements that are themselves linguistic or are at least expressible in language, logic reveals general features of the structure of language. This makes it essential to linguistics, and, on a Vittersian view, to metaphysics. Moreover, many philosophical battles have been fought with logical weaponry. For all these reasons, philosophers have tried to understand what logic is, what justifies it, and what it tells us about reason, language, and the world. The nature of logic. Logic might be defined as the science of inference; inference, in turn, as the drawing of a conclusion from premises. A simple argument is a sequence, one element of which, the conclusion, the others are thought to support. A complex argument is a series of simple arguments. Logic, then, is primarily concerned with arguments. Already, however, several questions arise. 1 Who thinks that the premises support the conclusion? The speaker? The audience? Any competent speaker of the language? 2 What are the elements of arguments? Thoughts? Propositions? Philosophers following Quine have found these answers unappealing for lack of clear identity criteria. Sentences are more concrete and more sharply individuated. But should we consider sentence tokens or sentence types? Context often affects interpretation, so it appears that we must consider tokens or types-in-context. Moreover, many sentences, even with contextual information supplied, are ambiguous. Is a sequence with an ambiguous sentence one argument which may be good on some readings and bad on others or several? For reasons that will become clear, the elements of arguments should be the primary bearers of truth and falsehood in one’s general theory of language. 3 Finally, and perhaps most importantly, what does ‘support’ mean? Logic evaluates inferences by distinguishing good from bad arguments. This raises issues about the status of logic, for many of its pronouncements are explicitly normative. The philosophy of logic thus includes problems of the nature and justification of norms akin to those arising in metaethics. The solutions, moreover, may vary with the logical system at hand. Some logicians attempt to characterize reasoning in natural language; others try to systematize reasoning in mathematics or other sciences. Still others try to devise an ideal system of reasoning that does not fully correspond to any of these. Logicians concerned with inference in natural, mathematical, or scientific languages tend to justify their norms by describing inferential practices in that language as actually used by those competent in it. These descriptions justify norms partly because the practices they describe include evaluations of inferences as well as inferences themselves. The scope of logic. Logical systems meant to account for natural language inference raise issues of the scope of logic. How does logic differ from semantics, the science of meaning in general? Logicians have often treated only inferences turning on certain commonly used words, such as ‘not’, ‘if’, ‘and’, ‘or’, ‘all’, and ‘some’, taking them, or items in a symbolic language that correspond to them, as logical constants. They have neglected inferences that do not turn on them, such as My brother is married. Therefore, I have a sister-in-law. Increasingly, however, semanticists have used ‘logic’ more broadly, speaking of the logic of belief, perception, abstraction, or even kinship.  Such uses seem to treat logic and semantics as coextensive. Philosophers who have sought to maintain a distinction between the semantics and logic of natural language have tried to develop non-arbitrary criteria of logical constancy. An argument is valid provided the truth of its premises guarantees the truth of its conclusion. This definition relies on the notion of truth, which raises philosophical puzzles of its own. Furthermore, it is natural to ask what kind of connection must hold between the premises and conclusion. One answer specifies that an argument is valid provided replacing its simple constituents with items of similar categories while leaving logical constants intact could never produce true premises and a false conclusion. On this view, validity is a matter of form: an argument is valid if it instantiates a valid form. Logic thus becomes the theory of logical form. On another view, an argument is valid if its conclusion is true in every possible world or model in which its premises are true. This conception need not rely on the notion of a logical constant and so is compatible with the view that logic and semantics are coextensive. Many issues in the philosophy of logic arise from the plethora of systems logicians have devised. Some of these are deviant logics, i.e., logics that differ from classical or standard logic while seeming to treat the same subject matter. Intuitionistic logic, for example, which interprets the connectives and quantifiers non-classically, rejecting the law of excluded middle and the interdefinability of the quantifiers, has been supported with both semantic and ontological arguments. Brouwer, Heyting, and others have defended it as the proper logic of the infinite; Dummett has defended it as the correct logic of natural language. Free logic allows non-denoting referring expressions but interprets the quantifiers as ranging only over existing objects. Many-valued logics use at least three truthvalues, rejecting the classical assumption of bivalence  that every formula is either true or false. Many logical systems attempt to extend classical logic to incorporate tense, modality, abstraction, higher-order quantification, propositional quantification, complement constructions, or the truth predicate. These projects raise important philosophical questions. Modal and tense logics. Tense is a pervasive feature of natural language, and has become important to computer scientists interested in concurrent programs. Modalities of several sorts  alethic possibility, necessity and deontic obligation, permission, for example  appear in natural language in various grammatical guises. Provability, treated as a modality, allows for revealing formalizations of metamathematics. Logicians have usually treated modalities and tenses as sentential operators. C. I. Lewis and Langford pioneered such approaches for alethic modalities; von Wright, for deontic modalities; and Prior, for tense. In each area, many competing systems developed; by the late 0s, there were over two hundred axiom systems in the literature for propositional alethic modal logic alone. How might competing systems be evaluated? Kripke’s semantics for modal logic has proved very helpful. Kripke semantics in effect treats modal operators as quantifiers over possible worlds. Necessarily A, e.g., is true at a world if and only if A is true in all worlds accessible from that world. Kripke showed that certain popular axiom systems result from imposing simple conditions on the accessibility relation. His work spawned a field, known as correspondence theory, devoted to studying the relations between modal axioms and conditions on models. It has helped philosophers and logicians to understand the issues at stake in choosing a modal logic and has raised the question of whether there is one true modal logic. Modal idioms may be ambiguous or indeterminate with respect to some properties of the accessibility relation. Possible worlds raise additional ontological and epistemological questions. Modalities and tenses seem to be linked in natural language, but attempts to bring tense and modal logic together remain young. The sensitivity of tense to intra- and extralinguistic context has cast doubt on the project of using operators to represent tenses. Kamp, e.g., has represented tense and aspect in terms of event structure, building on earlier work by Reichenbach. Truth. Tarski’s theory of truth shows that it is possible to define truth recursively for certain languages. Languages that can refer to their own sentences, however, permit no such definition given Tarski’s assumptions  for they allow the formulation of the liar and similar paradoxes. Tarski concluded that, in giving the semantics for such a language, we must ascend to a more powerful metalanguage. Kripke and others, however, have shown that it is possible for a language permitting self-reference to contain its own truth    680 predicate by surrendering bivalence or taking the truth predicate indexically. Higher-order logic. First-order predicate logic allows quantification only over individuals. Higher-order logics also permit quantification over predicate positions. Natural language seems to permit such quantification: ‘Mary has every quality that John admires’. Mathematics, moreover, may be expressed elegantly in higher-order logic. Peano arithmetic and Zermelo-Fraenkel set theory, e.g., require infinite axiom sets in firstorder logic but are finitely axiomatizable  and categorical, determining their models up to isomorphism  in second-order logic. Because they quantify over properties and relations, higher-order logics seem committed to Platonism. Mathematics reduces to higher-order logic; Quine concludes that the latter is not logic. Its most natural semantics seems to presuppose a prior understanding of properties and relations. Also, on this semantics, it differs greatly from first-order logic. Like set theory, it is incomplete; it is not compact. This raises questions about the boundaries of logic. Must logic be axiomatizable? Must it be possible, i.e., to develop a logical system powerful enough to prove every valid argument valid? Could there be valid arguments with infinitely many premises, any finite fragment of which would be invalid? With an operator for forming abstract terms from predicates, higher-order logics easily allow the formulation of paradoxes. Russell and Whitehead for this reason adopted type theory, which, like Tarski’s theory of truth, uses an infinite hierarchy and corresponding syntactic restrictions to avoid paradox. Type-free theories avoid both the restrictions and the paradoxes, as with truth, by rejecting bivalence or by understanding abstraction indexically. Refs.: H. P. Grice, “Why I don’t use ‘logic,’ but I use ‘semantic.’”Grice was careful with what he felt was an abuse of ‘semantic’ – v. Evans: “Meaning and truth: essayis in semantics.” “Well, that’s what ‘meaning’ means, right?” The semantics is more reated to the signatum than to the significatum. The Grecians did not have anything remotely similar to the significatum, which is all about the making (facere) of a sign (as in Grice’s example of the handwave). This is the meaning Grice gives to ‘semantics.’ There is no need for the handwave to be part of a system of communication, or have syntactic structure, or be ‘arbitrary.’ Still, one thing is communicated from the emissor to his recipient, and that is all count. “I know the route” is the message, or “I will leave you soon.” The handwave may be ambiguous. Grice is aware that formalists like Hilbert and Gentzen think that they can do without semantics – but as long as there is something ‘transmitted,’ or ‘messaged,’ it cannot. In the one-off predicament, Emissor E emits x and communicates that p. Since an intention with a content involving a psychological state is involved and attached, even in a one-off, to ‘x,’ we can legitimately say the scenario may be said to describe a ‘semantic’ phenomenon. Grice would freely use ‘semantic,’ and the root for ‘semantics,’ that Grice does use, involves the richest root of all Grecian roots: the ‘semion.’ Liddell and Scott have “τό σημεῖον,” Ion. σημήϊον , Dor. σα_μήϊον IG12(3).452 (Thera, iv B.C.), σα_μεῖον IPE12.352.25 (Chersonesus, ii B.C.), IG5(1).1390.16 (Andania, i B.C.), σα_μᾶον CIG5168 (Cyrene); = σῆμα in all senses, and more common in Prose, but never in Hom. or Hes.; and which they render as “mark by which a thing is known,” Hdt.2.38;” they also have “τό σῆμα,” Dor. σᾶμα Berl.Sitzb.1927.161 (Cyrene), etc.; which they render as “sign, mark, token,” “ Il.10.466, 23.326, Od.19.250, etc.” Grice lectured not only on Cat. But the next, De Int. As Arsitotle puts it, an expression is a symbol (symbolon) or sign (semeion) of an affections or impression (pathematon) of the soul (psyche). An affection of the soul, of which a word is  primarily a sign, are the same for the whole of mankind, as is also objects (pragmaton) of which the affections is a representation or likenes, image, or copiy (homoiomaton).  [De Int., 1.16a4]  while Grice is NOT concerned about the semantics of utterers meaning (how could he, when he analyses  means  in terms of  intends , he is about the semantics of  expression-meaning. Grices second stage (expression meaing) of his programme about meaning begins with specifications of means as applied to x, a token of X. He is having Tarski and Davidson in their elaborations of schemata like ‘p’ ‘means’ that p. ‘Snow is white’ ‘means’ that snow is white, and stuff! Grice was especially concerned with combinatories, for both unary and dyadic operators, and with multiple quantifications within a first-order predicate calculus with identity. Since in Grice’s initial elaboration on meaning he relies on Stevenson, it is worth exploring how ‘semantics’ and ‘semiotics’ were interpreted by Peirce and the emotivists. Stevenson’s main source is however in the other place, though, under Stevenson. Semantics – communication – H. P. Grice, “Implicaturum and Explicature: The basis of communication” – “Communication and Intention” -- philosophy of language, the philosophical study of natural language and its workings, particularly of linguistic meaning and the use of language. A natural language is any one of the thousands of various tongues that have developed historically among populations of human beings and have been used for everyday purposes  including English, , Swahili, and Latin  as opposed to the formal and other artificial “languages” invented by mathematicians, logicians, and computer scientists, such as arithmetic, the predicate calculus, and LISP or COBOL. There are intermediate cases, e.g., Esperanto, Pig Latin, and the sort of “philosophese” that mixes English words with logical symbols. Contemporary philosophy of language centers on the theory of meaning, but also includes the theory of reference, the theory of truth, philosophical pragmatics, and the philosophy of linguistics. The main question addressed by the theory of meaning is: In virtue of what are certain physical marks or noises meaningful linguistic expressions, and in virtue of what does any particular set of marks or noises have the distinctive meaning it does? A theory of meaning should also give a comprehensive account of the “meaning phenomena,” or general semantic properties of sentences: synonymy, ambiguity, entailment, and the like. Some theorists have thought to express these questions and issues in terms of languageneutral items called propositions: ‘In virtue of what does a particular set of marks or noises express the proposition it does?’; cf. ‘ “La neige est blanche” expresses the proposition that snow is white’, and ‘Synonymous sentences express the same proposition’. On this view, to understand a sentence is to “grasp” the proposition expressed by that sentence. But the explanatory role and even the existence of such entities are disputed. It has often been maintained that certain special sentences are true solely in virtue of their meanings and/or the meanings of their component expressions, without regard to what the nonlinguistic world is like ‘No bachelor is married’; ‘If a thing is blue it is colored’. Such vacuously true sentences are called analytic. However, Quine and others have disputed whether there really is such a thing as analyticity. Philosophers have offered a number of sharply competing hypotheses as to the nature of meaning, including: 1 the referential view that words mean by standing for things, and that a sentence means what it does because its parts correspond referentially to the elements of an actual or possible state of affairs in the world; 2 ideational or mentalist theories, according to which meanings are ideas or other psychological phenomena in people’s minds; 3 “use” theories, inspired by Vitters and to a lesser extent by J. L. Austin: a linguistic expression’s “meaning” is its conventionally assigned role as a game-piece-like token used in one or more existing social practices; 4 H. P. Grice’s hypothesis that a sentence’s or word’s meaning is a function of what audience response a typical utterer would intend to elicit in uttering it. 5 inferential role theories, as developed by Wilfrid Sellars out of Carnap’s and Vitters’s views: a sentence’s meaning is specified by the set of sentences from which it can correctly be inferred and the set of those which can be inferred from it Sellars himself provided for “language-entry” and “language-exit” moves as partly constitutive of meaning, in addition to inferences; 6 verificationism, the view that a sentence’s meaning is the set of possible experiences that would confirm it or provide evidence for its truth; 7 the truth-conditional theory: a sentence’s meaning is the distinctive condition under which it is true, the situation or state of affairs that, if it obtained, would make the sentence true; 8 the null hypothesis, or eliminativist view, that “meaning” is a myth and there is no such thing  a radical claim that can stem either from Quine’s doctrine of the indeterminacy of translation or from eliminative materialism in the philosophy of mind. Following the original work of Carnap, Alonzo Church, Hintikka, and Richard Montague in the 0s, the theory of meaning has made increasing use of “possible worlds”based intensional logic as an analytical apparatus. Propositions sentence meanings considered as entities, and truth conditions as in 7 above, are now commonly taken to be structured sets of possible worlds  e.g., the set of worlds in which Aristotle’s maternal grandmother hates broccoli. And the structure imposed on such a set, corresponding to the intuitive constituent structure of a proposition as the concepts ‘grandmother’ and ‘hate’ are constituents of the foregoing proposition, accounts for the meaning-properties of sentences that express the proposition. Theories of meaning can also be called semantics, as in “Gricean semantics” or “Verificationist semantics,” though the term is sometimes restricted to referential and/or truth-conditional theories, which posit meaning-constitutive relations between words and the nonlinguistic world. Semantics is often contrasted with syntax, the structure of grammatically permissible ordering relations between words and other words in well-formed sentences, and with pragmatics, the rules governing the use of meaningful expressions in particular speech contexts; but linguists have found that semantic phenomena cannot be kept purely separate either from syntactic or from pragmatic phenomena. In a still more specialized usage, linguistic semantics is the detailed study typically within the truth-conditional format of particular types of construction in particular natural languages, e.g., belief-clauses in English or adverbial phrases in Kwakiutl. Linguistic semantics in that sense is practiced by some philosophers of language, by some linguists, and occasionally by both working together. Montague grammar and situation semantics are common formats for such work, both based on intensional logic. The theory of referenceis pursued whether or not one accepts either the referential or the truthconditional theory of meaning. Its main question is: In virtue of what does a linguistic expression designate one or more things in the world? Prior to theorizing and defining of technical uses, ‘designate’, ‘denote’, and ‘refer’ are used interchangeably. Denoting expressions are divided into singular terms, which purport to designate particular individual things, and general terms, which can apply to more than one thing at once. Singular terms include proper names ‘Cindy’, ‘Bangladesh’, definite descriptions ‘my brother’, ‘the first baby born in the New World’, and singular pronouns of various types ‘this’, ‘you’, ‘she’. General terms include common nouns ‘horse’, ‘trash can’, mass terms ‘water’, ‘graphite’, and plural pronouns ‘they’, ‘those’. The twentieth century’s dominant theory of reference has been the description theory, the view that linguistic terms refer by expressing descriptive features or properties, the referent being the item or items that in fact possess those properties. For example, a definite description does that directly: ‘My brother’ denotes whatever person does have the property of being my brother. According to the description theory of proper names, defended most articulately by Russell, such names express identifying properties indirectly by abbreviating definite descriptions. A general term such as ‘horse’ was thought of as expressing a cluster of properties distinctive of horses; and so forth. But the description theory came under heavy attack in the late 0s, from Keith Donnellan, Kripke, and Putnam, and was generally abandoned on each of several grounds, in favor of the causal-historical theory of reference. The causal-historical idea is that a particular use of a linguistic expression denotes by being etiologically grounded in the thing or group that is its referent; a historical causal chain of a certain shape leads backward in time from the act of referring to the referents. More recently, problems with the causal-historical theory as originally formulated have led researchers to backpedal somewhat and incorporate some features of the description theory. Other views of reference have been advocated as well, particularly analogues of some of the theories of meaning listed above  chiefly 26 and 8. Modal and propositional-attitude contexts create special problems in the theory of reference, for referring expressions seem to alter their normal semantic behavior when they occur within such contexts. Much ink has been spilled over the question of why and how the substitution of a term for another term having exactly the same referent can change the truth-value of a containing modal or propositional-attitude sentence. Interestingly, the theory of truth historically predates articulate study of meaning or of reference, for philosophers have always sought the nature of truth. It has often been thought that a sentence is true in virtue of expressing a true belief, truth being primarily a property of beliefs rather than of linguistic entities; but the main theories of truth have also been applied to sentences directly. The correspondence theory maintains that a sentence is true in virtue of its elements’ mirroring a fact or actual state of affairs. The coherence theory instead identifies truth as a relation of the true sentence to other sentences, usually an epistemic relation. Pragmatic theories have it that truth is a matter either of practical utility or of idealized epistemic warrant. Deflationary views, such as the traditional redundancy theory and D. Grover, J. Camp, and N. D. Belnap’s prosentential theory, deny that truth comes to anything more important or substantive than what is already codified in a recursive Tarskian truth-definition for a language. Pragmatics studies the use of language in context, and the context-dependence of various aspects of linguistic interpretation. First, one and the same sentence can express different meanings or propositions from context to context, owing to ambiguity or to indexicality or both. An ambiguous sentence has more than one meaning, either because one of its component words has more than one meaning as ‘bank’ has or because the sentence admits of more than one possible syntactic analysis ‘Visiting doctors can be tedious’, ‘The mouse tore up the street’. An indexical sentence can change in truth-value from context to context owing to the presence of an element whose reference fluctuates, such as a demonstrative pronoun ‘She told him off yesterday’, ‘It’s time for that meeting now’. One branch of pragmatics investigates how context determines a single propositional meaning for a sentence on a particular occasion of that sentence’s use. Speech act theory is a second branch of pragmatics that presumes the propositional or “locutionary” meanings of utterances and studies what J. L. Austin called the illocutionary forces of those utterances, the distinctive types of linguistic act that are performed by the speaker in making them. E.g., in uttering ‘I will be there tonight’, a speaker might be issuing a warning, uttering a threat, making a promise, or merely offering a prediction, depending on conventional and other social features of the situation. A crude test of illocutionary force is the “hereby” criterion: one’s utterance has the force of, say, a warning, if it could fairly have been paraphrased by the corresponding “explicitly performative” sentence beginning ‘I hereby warn you that . . .’..Speech act theory interacts to some extent with semantics, especially in the case of explicit performatives, and it has some fairly dramatic syntactic effects as well. A third branch of pragmatics not altogether separate from the second is the theory of conversation or theory of implicaturum, founded by H. P. Grice. Grice notes that sentences, when uttered in particular contexts, often generate “implications” that are not logical consequences of those sentences ‘Is Jones a good philosopher?’  ’He has very neat handwriting’. Such implications can usually be identified as what the speaker meant in uttering her sentence; thus for that reason and others, what Grice calls utterer’s meaning can diverge sharply from sentence-meaning or “timeless” meaning. To explain those non-logical implications, Grice offered a now widely accepted theory of conversational implicaturum. Conversational implicaturums arise from the interaction of the sentence uttered with mutually shared background assumptions and certain principles of efficient and cooperative conversation. The philosophy of linguistics studies the academic discipline of linguistics, particularly theoretical linguistics considered as a science or purported science; it examines methodology and fundamental assumptions, and also tries to incorporate linguists’ findings into the rest of philosophy of language. Theoretical linguistics concentrates on syntax, and took its contemporary form in the 0s under Zellig Harris and Chomsky: it seeks to describe each natural language in terms of a generative grammar for that language, i.e., a set of recursive rules for combining words that will generate all and only the “well-formed strings” or grammatical sentences of that language. The set must be finite and the rules recursive because, while our informationprocessing resources for recognizing grammatical strings as such are necessarily finite being subagencies of our brains, there is no limit in any natural language either to the length of a single grammatical sentence or to the number of grammatical sentences; a small device must have infinite generative and parsing capacity. Many grammars work by generating simple “deep structures” a kind of tree diagram, and then producing multiple “surface structures” as variants of those deep structures, by means of rules that rearrange their parts. The surface structures are syntactic parsings of natural-language sentences, and the deep structures from which they derive encode both basic grammatical relations between the sentences’ major constituents and, on some theories, the sentences’ main semantic properties as well; thus, sentences that share a deep structure will share some fundamental grammatical properties and all or most of their semantics. As Paul Ziff and Davidson saw in the 0s, the foregoing syntactic problem and its solution had semantic analogues. From small resources, human speakers understand  compute the meanings of  arbitrarily long and novel sentences without limit, and almost instantaneously. This ability seems to require semantic compositionality, the thesis that the meaning of a sentence is a function of the meanings of its semantic primitives or smallest meaningful parts, built up by way of syntactic compounding. Compositionality also seems to be required by learnability, since a normal child can learn an infinitely complex dialect in at most two years, but must learn semantic primitives one at a time. A grammar for a natural language is commonly taken to be a piece of psychology, part of an explanation of speakers’ verbal abilities and behavior. As such, however, it is a considerable idealization: it is a theory of speakers’ linguistic “competence” rather than of their actual verbal performance. The latter distinction is required by the fact that speakers’ considered, reflective judgments of grammatical correctness do not line up very well with the class of expressions that actually are uttered and understood unreflectively by those same speakers. Some grammatical sentences are too hard for speakers to parse quickly; some are too long to finish parsing at all; speakers commonly utter what they know to be formally ungrammatical strings; and real speech is usually fragmentary, interspersed with vocalizations, false starts, and the like. Actual departures from formal grammaticality are ascribed by linguists to “performance limitations,” i.e., psychological factors such as memory failure, weak computational capacity, or heedlessness; thus, actual verbal behavior is to be explained as resulting from the perturbation of competence by performance limitations.  Refs.: The main sources are his lectures on language and reality – part of them repr. in WOW. The keywords under ‘communication,’ and ‘signification,’ that Grice occasionally uses ‘the total signification’ of a remark, above, BANC. -- semantic holism, a metaphysical thesis about the nature of representation on which the meaning of a symbol is relative to the entire system of representations containing it. Thus, a linguistic expression can have meaning only in the context of a language; a hypothesis can have significance only in the context of a theory; a concept can have intentionality only in the context of the belief system. Holism about content has profoundly influenced virtually every aspect of contemporary theorizing about language and mind, not only in philosophy, but in linguistics, literary theory, artificial intelligence, psychology, and cognitive science. Contemporary semantic holists include Davidson, Quine, Gilbert Harman, Hartry Field, and Searle. Because semantic holism is a metaphysical and not a semantic thesis, two theorists might agree about the semantic facts but disagree about semantic holism. So, e.g., nothing in Tarski’s writings determines whether the semantic facts expressed by the theorems of an absolute truth semantic atomism semantic holism 829    829 theory are holistic or not. Yet Davidson, a semantic holist, argued that the correct form for a semantic theory for a natural language L is an absolute truth theory for L. Semantic theories, like other theories, need not wear their metaphysical commitments on their sleeves. Holism has some startling consequences. Consider this. Franklin D. Roosevelt who died when the United States still had just forty-eight states did not believe there were fifty states, but I do; semantic holism says that what ‘state’ means in our mouths depends on the totality of our beliefs about states, including, therefore, our beliefs about how many states there are. It seems to follow that he and I must mean different things by ‘state’; hence, if he says “Alaska is not a state” and I say “Alaska is a state” we are not disagreeing. This line of argument leads to such surprising declarations as that natural langauges are not, in general, intertranslatable Quine, Saussure; that there may be no fact of the matter about the meanings of texts Putnam, Derrida; and that scientific theories that differ in their basic postulates are “empirically incommensurable” Paul Feyerabend, Kuhn. For those who find these consequences of semantic holism unpalatable, there are three mutually exclusive responses: semantic atomism, semantic molecularism, or semantic nihilism. Semantic atomists hold that the meaning of any representation linguistic, mental, or otherwise is not determined by the meaning of any other representation. Historically, Anglo- philosophers in the eighteenth and nineteenth centuries thought that an idea of an X was about X’s in virtue of this idea’s physically resembling X’s. Resemblance theories are no longer thought viable, but a number of contemporary semantic atomists still believe that the basic semantic relation is between a concept and the things to which it applies, and not one among concepts themselves. These philosophers include Dretske, Dennis Stampe, Fodor, and Ruth Millikan. Semantic molecularism, like semantic holism, holds that the meaning of a representation in a language L is determined by its relationships to the meanings of other expressions in L, but, unlike holism, not by its relationships to every other expression in L. Semantic molecularists are committed to the view, contrary to Quine, that for any expression e in a language L there is an in-principle way of distinguishing between those representations in L the meanings of which determine the meaning of e and those representations in L the meanings of which do not determine the meaning of e. Traditionally, this inprinciple delimitation is supported by an analytic/synthetic distinction. Those representations in L that are meaning-constituting of e are analytically connected to e and those that are not meaning-constituting are synthetically connected to e. Meaning molecularism seems to be the most common position among those philosophers who reject holism. Contemporary meaning molecularists include Michael Devitt, Dummett, Ned Block, and John Perry. Semantic nihilism is perhaps the most radical response to the consequences of holism. It is the view that, strictly speaking, there are no semantic properties. Strictly speaking, there are no mental states; words lack meanings. At least for scientific purposes and perhaps for other purposes as well we must abandon the notion that people are moral or rational agents and that they act out of their beliefs and desires. Semantic nihilists include among their ranks Patricia and Paul Churchland, Stephen Stich, Dennett, and, sometimes, Quine.  -- semantic paradoxes, a collection of paradoxes involving the semantic notions of truth, predication, and definability. The liar paradox is the oldest and most widely known of these, having been formulated by Eubulides as an objection to Aristotle’s correspondence theory of truth. In its simplest form, the liar paradox arises when we try to assess the truth of a sentence or proposition that asserts its own falsity, e.g.: A Sentence A is not true. It would seem that sentence A cannot be true, since it can be true only if what it says is the case, i.e., if it is not true. Thus sentence A is not true. But then, since this is precisely what it claims, it would seem to be true. Several alternative forms of the liar paradox have been given their own names. The postcard paradox, also known as a liar cycle, envisions a postcard with sentence B on one side and sentence C on the other: B The sentence on the other side of this card is true. semantic molecularism semantic paradoxes 830    830 C The sentence on the other side of this card is false. Here, no consistent assignment of truth-values to the pair of sentences is possible. In the preface paradox, it is imagined that a book begins with the claim that at least one sentence in the book is false. This claim is unproblematically true if some later sentence is false, but if the remainder of the book contains only truths, the initial sentence appears to be true if and only if false. The preface paradox is one of many examples of contingent liars, claims that can either have an unproblematic truth-value or be paradoxical, depending on the truth-values of various other claims in this case, the remaining sentences in the book. Related to the preface paradox is Epimenedes’ paradox: Epimenedes, himself from Crete, is said to have claimed that all Cretans are liars. This claim is paradoxical if interpreted to mean that Cretans always lie, or if interpreted to mean they sometimes lie and if no other claim made by Epimenedes was a lie. On the former interpretation, this is a simple variation of the liar paradox; on the latter, it is a form of contingent liar. Other semantic paradoxes include Berry’s paradox, Richard’s paradox, and Grelling’s paradox. The first two involve the notion of definability of numbers. Berry’s paradox begins by noting that names or descriptions of integers consist of finite sequences of syllables. Thus the three-syllable sequence ‘twenty-five’ names 25, and the seven-syllable sequence ‘the sum of three and seven’ names ten. Now consider the collection of all sequences of English syllables that are less than nineteen syllables long. Of these, many are nonsensical ‘bababa’ and some make sense but do not name integers ‘artichoke’, but some do ‘the sum of three and seven’. Since there are only finitely many English syllables, there are only finitely many of these sequences, and only finitely many integers named by them. Berry’s paradox arises when we consider the eighteen-syllable sequence ‘the smallest integer not nameable in less than nineteen syllables’. This phrase appears to be a perfectly well-defined description of an integer. But if the phrase names an integer n, then n is nameable in less than nineteen syllables, and hence is not described by the phrase. Richard’s paradox constructs a similarly paradoxical description using what is known as a diagonal construction. Imagine a list of all finite sequences of letters of the alphabet plus spaces and punctuation, ordered as in a dictionary. Prune this list so that it contains only English definitions of real numbers between 0 and 1. Then consider the definition: “Let r be the real number between 0 and 1 whose kth decimal place is  if the kth decimal place of the number named by the kth member of this list is 1, and 0 otherwise’. This description seems to define a real number that must be different from any number defined on the list. For example, r cannot be defined by the 237th member of the list, because r will differ from that number in at least its 237th decimal place. But if it indeed defines a real number between 0 and 1, then this description should itself be on the list. Yet clearly, it cannot define a number different from the number defined by itself. Apparently, the definition defines a real number between 0 and 1 if and only if it does not appear on the list of such definitions. Grelling’s paradox, also known as the paradox of heterologicality, involves two predicates defined as follows. Say that a predicate is “autological” if it applies to itself. Thus ‘polysyllabic’ and ‘short’ are autological, since ‘polysyllabic’ is polysyllabic, and ‘short’ is short. In contrast, a predicate is “heterological” if and only if it is not autological. The question is whether the predicate ‘heterological’ is heterological. If our answer is yes, then ‘heterological’ applies to itself  and so is autological, not heterological. But if our answer is no, then it does not apply to itself  and so is heterological, once again contradicting our answer. The semantic paradoxes have led to important work in both logic and the philosophy of language, most notably by Russell and Tarski. Russell developed the ramified theory of types as a unified treatment of all the semantic paradoxes. Russell’s theory of types avoids the paradoxes by introducing complex syntactic conditions on formulas and on the definition of new predicates. In the resulting language, definitions like those used in formulating Berry’s and Richard’s paradoxes turn out to be ill-formed, since they quantify over collections of expressions that include themselves, violating what Russell called the vicious circle principle. The theory of types also rules out, on syntactic grounds, predicates that apply to themselves, or to larger expressions containing those very same predicates. In this way, the liar paradox and Grelling’s paradox cannot be constructed within a language conforming to the theory of types. Tarski’s attention to the liar paradox made two fundamental contributions to logic: his development of semantic techniques for defining the truth predicate for formalized languages and his proof of Tarski’s theorem. Tarskian semantics avoids the liar paradox by starting with a formal language, call it L, in which no semantic notions are expressible, and hence in which the liar paradox cannot be formulated. Then using another language, known as the metalanguage, Tarski applies recursive techniques to define the predicate true-in-L, which applies to exactly the true sentences of the original language L. The liar paradox does not arise in the metalanguage, because the sentence D Sentence D is not true-in-L. is, if expressible in the metalanguage, simply true. It is true because D is not a sentence of L, and so a fortiori not a true sentence of L. A truth predicate for the metalanguage can then be defined in yet another language, the metametalanguage, and so forth, resulting in a sequence of consistent truth predicates. Tarski’s theorem uses the liar paradox to prove a significant result in logic. The theorem states that the truth predicate for the first-order language of arithmetic is not definable in arithmetic. That is, if we devise a systematic way of representing sentences of arithmetic by numbers, then it is impossible to define an arithmetical predicate that applies to all and only those numbers that represent true sentences of arithmetic. The theorem is proven by showing that if such a predicate were definable, we could construct a sentence of arithmetic that is true if and only if it is not true: an arithmetical version of sentence A, the liar paradox. Both Russell’s and Tarski’s solutions to the semantic paradoxes have left many philosophers dissatisfied, since the solutions are basically prescriptions for constructing languages in which the paradoxes do not arise. But the fact that paradoxes can be avoided in artificially constructed languages does not itself give a satisfying explanation of what is going wrong when the paradoxes are encountered in natural language, or in an artificial language in which they can be formulated. Most recent work on the liar paradox, following Kripke’s “Outline of a Theory of Truth” 5, looks at languages in which the paradox can be formulated, and tries to provide a consistent account of truth that preserves as much as possible of the intuitive notion.

semeiotics: semiological: or is it semiotics? Cf. semiological, semotic. Since Grice uses ‘philosophical psychology’ and ‘philosopical biology,’ it may do to use ‘semiology,’ indeed ‘philosophical semiology,’ here.  Oxonian semiotics is unique. Holloway published his “Language and Intelligence” and everyone was excited. It is best to see this as Grices psychologism. Grice would rarely use ‘intelligent,’ less so the more pretentious, ‘intelligence,’ as a keyword. If he is doing it, it is because what he saw as the misuse of it by Ryle and Holloway. Holloway, a PPE, is a tutorial fellow in philosophy at All Souls. He acknowledges Ryle as his mentor. (Holloway also quotes from Austin). Grice was amused that J. N. Findlay, in his review of Holloway’s essay in “Mind,” compares Holloway to C. W. Morris, and cares to cite the two relevant essay by Morris: The Foundation in the theory of signs, and Signs, Language, and Behaviour. Enough for Grice to feel warmly justified in having chosen another New-World author, Peirce, for his earlier Oxford seminar. Morris studied under G. H. Mead. But is ‘intelligence’ part of The Griceian Lexicon?Well, Lewis and Short have ‘interlegere,’ to chose between. Lewis and Short have ‘interlĕgo , lēgi, lectum, 3, v. a., I’.which they render it as “to cull or pluck off here and there (poet. and postclass.).in tmesi) uncis Carpendae manibus frondes, interque legendae, Verg. G. 2, 366: “poma,” Pall. Febr. 25, 16; id. Jun. 5, 1.intellĕgo (less correctly intellĭgo), exi, ectum (intellexti for intellexisti, Ter. Eun. 4, 6, 30; Cic. Att. 13, 32, 3: I.“intellexes for intellexisses,” Plaut. Cist. 2, 3, 81; subj. perf.: “intellegerint,” Sall. H. Fragm. 1, 41, 23 Dietsch); “inter-lego,” “to see into, perceive, understand.” I. Lit. A. Lewis and Short render as “to perceive, understand, comprehend.” Cf. Grice on his handwriting being legible to few. And The child is an adult as being UNintelligible until the creature is produced. In “Aspects,” he mentions flat rationality, and certain other talents that are more difficult for the philosopher to conceptualise, such as nose (i.e. intuitiveness), acumen, tenacity, and such. Grices approach is Pological. If Locke had used intelligent to refer to Prince Maurices parrot, Grice wants to find criteria for intelligent as applied to his favourite type of P, rather (intelligent, indeed rational.). semiosis from Grecian semeiosis, ‘observation of signs’, the relation of signification involving the three relata of sign, object, and mind. Semiotic is the science or study of semiosis. The semiotic of John of Saint Thomas and of Peirce includes two distinct components: the relation of signification and the classification of signs. The relation of signification is genuinely triadic and cannot be reduced to the sum of its three subordinate dyads: sign-object, sign-mind, object-mind. A sign represents an object to a mind just as A gives a gift to B. Semiosis is not, as it is often taken to be, a mere compound of a sign-object dyad and a sign-mind dyad because these dyads lack the essential intentionality that unites mind with object; similarly, the gift relation involves not just A giving and B receiving but, crucially, the intention uniting A and B. In the Scholastic logic of John of Saint Thomas, the sign-object dyad is a categorial relation secundum esse, that is, an essential relation, falling in Aristotle’s category of relation, while the sign-mind dyad is a transcendental relation secundum dici, that is, a relation only in an analogical sense, in a manner of speaking; thus the formal rationale of semiosis is constituted by the sign-object dyad. By contrast, in Peirce’s logic, the sign-object dyad and the sign-mind dyad are each only potential semiosis: thus, the hieroglyphs of ancient Egypt were merely potential signs until the discovery of the Rosetta Stone, just as a road-marking was a merely potential sign to the driver who overlooked it. Classifications of signs typically follow from the logic of semiosis. Thus John of Saint Thomas divides signs according to their relations to their objects into natural signs smoke as a sign of fire, customary signs napkins on the table as a sign that dinner is imminent, and stipulated signs as when a neologism is coined; he also divides signs according to their relations to a mind. An instrumental sign must first be cognized as an object before it can signify e.g., a written word or a symptom; a formal sign, by contrast, directs the mind to its object without having first been cognized e.g., percepts and concepts. Formal signs are not that which we cognize but that by which we cognize. All instrumental signs presuppose the action of formal signs in the semiosis of cognition. Peirce similarly classified signs into three trichotomies according to their relations with 1 themselves, 2 their objects, and 3 their interpretants usually minds; and Charles Morris, who followed Peirce closely, called the relationship of signs to one another the syntactical dimension of semiosis, the relationship of signs to their objects the semantical dimension of semiosis, and the relationship of signs to their interpreters the pragmatic dimension of semiosis.  Refs.: The most specific essay is his lecture on Peirce, listed under ‘communication, above.

sender: Grice: “Surely, if there is a ‘recipient,’ there must be a ‘sender.’” Grice: “I prefer ‘sender’ as correlative for ‘recipient,’ since there is an embedded intentionality about it.” Cf. Sting, “Message in a bottle – sending out an S. O. S.” – Grice: “Addresser and addressee sound otiose.” – Grice: “Then there’s this jargon of the ‘target’ addressee’ – while we are in the metaphorical mode!” -- emissor: utterer: cf. emissum, emissor. Usually Homo sapiens sapiens – and usually Oxonian, the Homo sapiens sapiens Grice interactes with. Sometimes tutees, sometimes tutor. There is something dualistic about the ‘utterer.’ It is a vernacularism from English ‘out.’ So the French impressionists were into IM-pressing, out to in; the German expressionists were into EX-pressing, in to out. Or ‘man’. The important thing is for Grice to avoid ‘speaker.’ He notes that ‘utterance’ has a nice fuzziness about it. He still notes that he is using ‘utter’ in a ‘perhaps artificial’ way. He was already wedded to ‘utter’ in  his talk for the Oxford Philosopical Society. Grice does not elaborate much on general gestures or signals. His main example is a sort of handwave by which the emissor communicates that either he knows the route or that he is about to leave the addressee. Even this is complex. Let’s try to apply his final version of communication to the hand-wave. The question of “Homo sapiens sapiens” is an interesting one. Grice is all for ascribing predicates regarding the soul to what he calls the ‘lower animals’. He is not ready to ascribe emissor’s meaning to them. Why? Because of Schiffer! I mean, when it comes to the conditions of necessity of the reductive analysis, he seems okay. When it comes to the sufficiency, there are two types of objection. One by Urmson, easily dismissed. The second, first by Stampe and Strawson, not so easily. But Grice agrees to add a clause limiting intentions to be ‘in the open.’ Those who do not have a philosophical background usually wonder about this. So for their sake, it may be worth considering Grice’s synthetic a posteriori argument to refuse an emissor other than a Homo sapiens sapiens to be able to ‘mean,’ if not ‘communicate,’ or ‘signify.’ There is an objection which is not mentioned by his editors, which seems to Grice to be one to which Grice must respond. The objection may be stated thus. One of the leading strands in Grice’s reductive analysis of an emissor communicating that p is that communication is not to be regarded exclusively, or even primarily, as a ‘feature’ of emissors who use what philosophers of language call ‘language’ (Sprache, Taal, Langage, Linguaggio – to restrict to the philosophical lexicon, cf. Plato’s Cratylus), and a fortiori of an emissor who emits this or that “linguistic” ‘utterance.’ There are many instances of NOTABLY NON-“linguistic” vehicles or devices of communication, within a communication-system, which fulfil this or that communication-function; these vehicles or devices are mostly syntactically un-structured or amorphous. Sometimes, a device may exhibit at least some rudimentary syntactic structure, in that we may distinguish a totum from a pars and identify a ‘simplex’ within a ‘complexum.’ Grice’s intention-based reductive analysis of a communicatum, based on Aristotle, Locke, and Peirce, is designed to allow for the possibility that a non-“linguistic,” and, further, indeed a non-“conventional” 'utterance' token, perhaps even manifesting some degree of syntactic structure, and not just a block of an amorphous signal, may be within the ‘repertoire’ of ‘procedures’ of this or that organism, or creature, or agent, which, even if not relying on any apparatus for communication of the kind that that we may label ‘linguistic’ or otherwise ‘conventional,’  ‘do’ this or that ‘thing’ thereby ‘communicating’ that p, or q. To provide for this possibility, it is plainly necessary that the key ingredient in any representation of ‘communicating,’ viz. intending that p, should be a ‘state’ of the emissor’s soul the capacity for which does not require what we may label the ‘possession’ of, shall we say, a ‘faculty,’ of what philosophers call ‘a’ ‘language’ (Sprache, Taal, langue, lingua – note that in German we do not distinguish between ‘die Deutsche Sprache’ and ‘Sprache’ as ‘ein Facultat.’). Now a philosopher, relying on this or that neo-Prichardian reductive analysis of ‘intending that p,’ may not be willing to allow the possibility of such, shall we call it, pre-linguistic intending that p, or non-linguistic intending that p. Surely if the emissor realizes that his addressee does not share what the Germans call ‘die Deutsche Sprache,” the emissor may still communicate with his addresse this or that by doing this or that. E. g. he may simulate that he wants to smoke a cigarette and wonders if his addressee has one to spare. Against that objection, Grice surely wins the day. But Grice grants that winning the day on THAT front may not be enough. And that is because, as far as Grice’s Oxonian explorations on communication go, in a succession of increasingly elaborate moves – ending with a ‘closure’ clause which cut this succession of increasingly elaborate moves -- designed to thwart this or that scenario, later deemed illegitimate, involving two rational agents where the emissor relies on an ‘inference-element’ that it is not the case that he intends his addressee will recogise – Grice is led to restrict the ‘intending’ which is to constitute a case of an emissor communicating that p to C-intending. Grice suspects that whatever may be the case in general with regard to ‘intending,’ C-intending seems for some reason to Grice to be unsophisticatedly, viz. plainly, too sophisticated a ‘state’ of a soul to be found in an organism, ‘pirot,’ creature, that we may not want to deem ‘rational,’ or as the Germans would say, a creature that is destitute of “Die Deutsche Sprache.” We need the pirot to be “very intelligent, indeed rational.”Grice regrets that some may think that what he thought were unavoidable rear-guard actions (ending with a complex reductive analysis of C-intending) seem to have undermined the raison d'etre of the Griciean campaign.”Unfortunately, Grice provides what he admittedly labels “a brief reply” which “will have to suffice.” Why? Because “a full treatment would require delving deep into crucial problems concerning the boundaries between vicious and virtuous circularity.” Which is promising. It is not something totally UNATTAINABLE. It reduces to the philosopher being virtuously circular, only! Why is the ‘virtuous circle’ so crucial – vide ‘circulus virtuosus.’ virtŭōsus , a, um, adj. virtus, I.virtuousgood (late Lat.), Aug. c. Sec. Man. 10. A circle is virtuous if it is not that bad. In this case, we need the ‘virtuous circle’ because we are dealing with ‘a loop.’ This is exactly Schiffer’s way of putting it in his ‘Introduction’ to Meaning (second edition). There is a ‘conceptual loop.’ Schiffer is not interested in ‘communicating;’ only ‘meaning.’ But his point can be transferred. He is saying that ‘U means that p,’ may rely on ‘U intends that p,’ where ‘U intends that p’ relies on ‘U means that p.’ There is a loop. In more generic terms:We have a creature, call it a pirot P1 that, by doing thing T, communicates that p. Are we talking of the OBSERVER? I hope so, because Grice’s favourite pirot is the parrot. So we have Prince Maurice’s Parrot. Locke: Since I think I may be confident, that, whoever should see a CREATURE of his own shape or make, though it had no more reason all its life than a cat or a PARROT, would call him still A MAN; or whoever should hear a cat or a parrot discourse, reason, and philosophize, would call or think it nothing but a cat or a PARROT; and say, the one was A DULL IRRATIONAL MAN, and the other A VERY INTELLIGENT RATIONAL PARROT. A relation we have in an author of great note, is sufficient to countenance the supposition of A RATIONAL PARROT. The author’s words are: I had a mind to know, from Prince Maurice's own mouth, the account of a common, but much credited story, that I had heard so often from many others, of an old parrot he has, that speaks, and asks, and answers common questions, like A REASONABLE CREATURE. So that those of his train there generally conclude it to be witchery or possession; and one of his chaplains, would never from that time endure A PARROT, but says all PARROTS have a devil in them. I had heard many particulars of this story, and as severed by people hard to be discredited, which made me ask Prince Maurice what there is of it. Prince Maurice says, with his usual plainness and dryness in talk, there is something true, but a great deal false of what is reported. I desired to know of him what there was of the first. Prince Maurice tells me short and coldly, that he had HEARD of such A PARROT; and though he believes nothing of it, and it was a good way off, yet he had so much curiosity as to send for the parrot: that it was a very great parrot; and when the parrot comes first into the room where Prince Maurice is, with a great many men about him, the parrot says presently, What a nice company is here. One of the men asks the parrot, ‘What thinkest thou that man is?,’ ostending his finger, and pointing to Prince Maurice. The parrot answers, ‘Some general -- or other.’ When the man brings the parrot close to Prince Maurice, Prince Maurice asks the parrot., “D'ou venez-vous?” The parrot answers, “De Marinnan.” Then Prince Maurice goes on, and poses a second question to the parrot. “A qui estes-vous?” The Parrot answers: “A un Portugais.” Prince Maurice asks a third question. “Que fais-tu la?” The parrot answers: “Je garde les poulles.”Prince Maurice smiles, which pleases the Parrot. Prince Maurice, violating a Griceian maxim, and being just informed that p, asks whether p. This is his fourth question. “Vous gardez les poulles?” The Parrot answers, “Oui, moi; et je scai bien faire.” The Parrott appeals to Peirce’s iconic system and makes the chuck four or five times that a man uses to make to chickens when a man calls them. I set down the words of this worthy dialogue in French, just as Prince Maurice said them to me. I ask Prince Maurice in what ‘language’ the parrot speaks. Prince Maurice says that the parrot speaks in Brazilian. I ask Prince William whether he understands the Brazilian language. Prince Maurice says: No, but he has taken care to have TWO interpreters by him, the one a Dutchman that spoke Brazilian, and the other a Brazilian that spoke Dutch; that Prince Maurice asked them separatelyand privately, and both of them AGREED in telling Prince Maurice just the same thing that the parrot had said. I could not but tell this ODD story, because it is so much out of the way, and from the first hand, and what may pass for a good one; for I dare say Prince Maurice at least believed himself in all he told me, having ever passed for a very honest and pious man. I leave it to naturalists to reason, and to other men to believe, as they please upon it. However, it is not, perhaps, amiss to relieve or enliven a busy scene sometimes with such digressions, whether to the purpose or no.Locke takes care that the reader should have the story at large in the author's own words, because he seems to me not to have thought it incredible.For it cannot be imagined that so able a man as he, who had sufficiency enough to warrant all the testimonies he gives of himself, should take so much pains, in a place where it had nothing to do, to pin so close, not only on a man whom he mentions as his friend, but on a prince in whom he acknowledges very great honesty and piety, a story which, if he himself thought incredible, he could not but also think RIDICULOUS. Prince Maurice, it is plain, who vouches this story, and our author, who relates it from him, both of them call this talker A PARROT. And Locke asks any one else who thinks such a story fit to be told, whether, if this PARROT, and all of its kind, had always talked, as we have a prince's word for it this one did,- whether, I say, they would not have passed for a race of RATIONAL ANIMALS; but yet, whether, for all that, they would have been allowed to be MEN, and not PARROTS? For I presume it is not the idea of A THINKING OR RATIONAL BEING alone that makes the idea of A MAN in most people's sense: but of A BODY, so and so shaped, joined to it: and if that be the idea of a MAN, the same successive body not shifted all at once, must, as well as  THE SAME IMMATERIAL SPIRIT, go to the making of the same MAN. So back to Grice’s pirotology.But first a precis of the conversation, or languaging:PARROT: What a nice company is here.MAN (pointing to Prince Maurice): What thinkest thou that man is?PARROT: Some general -- or other. (i. e. the parrot displays what Grice calls ‘up-take.’ The parrot recognizes the man’s c-intention. So far is ability to display uptake.PRINCE MAURICE: D'ou venez-vous?PARROT: De Marinnan.PRINCE MAURICE: A qui estes-vous?PARROT: A un Portugais.PRINCE MAURICE: Que fais-tu la?PARROT: Je garde les poulles.PRINCE MAURICE SMILES and flouts a Griceian maxim: Vous gardez les poulles?PARROT (losing patience, and grasping the Prince’s implicaturum that he doubts it): Oui, moi. Et je scai bien faire.(The Parrott then appeals to Peirce’s iconic system and makes the chuck five times that a man uses to make to chickens when a man calls them.)So back to Grice:“According to my most recent speculations about communication, one should distinguish between what I call the ‘factual’ or ‘de facto’ character of behind the state of affairs that one might describe as ‘rational agent A communicates that p,’ for those communication-relevant features which obtain or are present in the circumstances) the ‘titular’ or ‘de jure’ character, viz. the nested C-intending which is only deemed to be present. And the reason Grice calls it ‘nested’ is that it involves three sub-intentions:(C) Emissor E communicates that (psi*) p iff Emissor E c-intends that A recognises that E psi-s that p iffC1: Emissor E intends A to recognise that A psi-s that p.C2: Emissor intends that A recognise C1 by A recognising C2C3: There is no inference-element which is C-constitutive such that Emissor relies on it and yet does not intend A to recognise.Grice:“The titular or de jure character of the state of affairs that is described as “Emissor communicates that p,” involves self-reference in the closure clause regarding the third intention, C3, may be thought as being ‘regressive,’ or involving what mathematicians mean when they use “, …;” and the translators of Aristotle, ‘eis apeiron,’ translated as ‘ad infinitum.’There may be ways of UNDEEMING this, i. e. of stating that self-reference and closure are meant to BLOCK an infinite regress. Hence the circle, if there is one – one feature of a virtuous circle is that it doesn’t look like a circle simpliciter --  would be virtuous. The ‘de jure’ character stands for a situation which, in Grice’s words, is “infinitely complex,” and so cannot be actually present in toto – only DEEMED to be.”“In which case,” Grice concludes pointing to the otiosity or rendering inoperative, “to point out that THE INCONCEIVABLE actual presence of the ‘de jure’ character of ‘Emissor communicates that p’ WOULD, still, be possible, or would be detectable, only via the ‘use’ of something like ‘die Deutsche Sprache’ seem to serve little, if any, purpose.”“At its most meagre, the factual or ‘de facto’ character consists merely in the pre-rational ‘counterpart’ of the state of affairs describable by “Emissor E communicates that p,” which might amount to no more than making a certain sort of utterance in order thereby to get some creature to think or want some particular thing.This meagre condition does not involve a reference to any expertise regarding anything like ‘die Deutsche Sprache.’Let’s reformulate the condition.It’s just a pirot, at a ‘pre-rational’ level. The pirot does a thing T IN ORDER THEREBY to get some other pirot to think or do some particular thing. To echo Hare,Die Tur ist geschlossen, ja.Die Tur ist geschlossen, bitte.Grice continues as a corollary: “Maybe in a less straightforward instance of “Emissor E communicates that p” there is actually present the C-intention whose feasibility as an ‘intention’ suggests some ability to use ‘die Deutsche Sprache.’But vide “non-verbal communication,” pre-verbal communication, languaging, pre-conventional communication, gestural communication – as in What Grice has as “a gesture (a signal).” Not necessary ‘conventional,’ and MAYBE ‘established’ – is one-off sufficient for ‘established’? I think so. By waving his hand in a particular way (“a particular sort of hand wave”), the emissor communicates that he knows the route (or is about to leave the addressee).  Grice concludes about the less straightforward instances, that there can be no advance guarantee when this will be so, i. e. that there is actually present the C-intention whose feasibility as an intention points to some capacity to use ‘die Deutsche Sprache.’Grice adds: “It is in any case arguable that the use of ‘die Deutsche Sprache’ would here be an indispensable aid to philosophising about communication, rather than it being an element in the PHILOSOPHISING about communication!  Philosophers of Grice’s generation use ‘man’ on purpose to mean ‘mankind’. What a man means. What a man utters. The utterer is the man. In semiotics one can use something more Latinate, like gesturer, or emitter – or profferer. The distinction is between what an utterer means and what the logical and necessary implication. He doesn’t need to say this since ‘imply’ in the logical usage does not take utterer as subject. It’s what the utterer SAYS that implies this or that. (Strawson and Wiggins, p. 519). The utterer is possibly the ‘expresser.’

senone: (or as Strawson would prefer, Zeno). "Senone *loved* his native Velia. Vivid evidence of the cultural impact of Senone's arguments in Italia is to be found in the interior of a red-figure drinking cup (Roma, Villa Giulia, inv. 3591) discovered in the Etrurian city of Falerii. It depicts a heroic figure racing nimbly ahead of a large tortoise and has every appearance of being the first known ‘response’ to the Achilles (or Mercurio, Ermete) paradox. “Was ‘Senone’ BORN in Velia?” – that is the question!” – Grice. Italian philosopher, as as such, or as Grice prefers, ‘senone’ -- Zenos paradoxes. “Since Elea is in Italy, we can say Zeno is Italian.” – H. P. Grice. “Linguistic puzzles, in nature.”  H. P. Grice. four paradoxes relating to space and motion attributed to Zeno of Elea fifth century B.C.: the racetrack, Achilles and the tortoise, the stadium, and the arrow. Zeno’s work is known to us through secondary sources, in particular Aristotle. The racetrack paradox. If a runner is to reach the end of the track, he must first complete an infinite number of different journeys: getting to the midpoint, then to the point midway between the midpoint and the end, then to the point midway between this one and the end, and so on. But it is logically impossible for someone to complete an infinite series of journeys. Therefore the runner cannot reach the end of the track. Since it is irrelevant to the argument how far the end of the track is  it could be a foot or an inch or a micron away  this argument, if sound, shows that all motion is impossible. Moving to any point will involve an infinite number of journeys, and an infinite number of journeys cannot be completed. The paradox of Achilles and the tortoise. Achilles can run much faster than the tortoise, so when a race is arranged between them the tortoise is given a lead. Zeno argued that Achilles can never catch up with the tortoise no matter how fast he runs and no matter how long the race goes on. For the first thing Achilles has to do is to get to the place from which the tortoise started. But the tortoise, though slow, is unflagging: while Achilles was occupied in making up his handicap, the tortoise has advanced a little farther. So the next thing Achilles has to do is to get to the new place the tortoise occupies. While he is doing this, the tortoise will have gone a little farther still. However small the gap that remains, it will take Achilles some time to cross it, and in that time the tortoise will have created another gap. So however fast Achilles runs, all that the tortoise has to do, in order not to be beaten, is not to stop. The stadium paradox. Imagine three equal cubes, A, B, and C, with sides all of length l, arranged in a line stretching away from one. A is moved perpendicularly out of line to the right by a distance equal to l. At the same time, and at the same rate, C is moved perpendicularly out of line to the left by a distance equal to l. The time it takes A to travel l/2 relative to B equals the time it takes A to travel to l relative to C. So, in Aristotle’s words, “it follows, Zeno thinks, that half the time equals its double” Physics 259b35. The arrow paradox. At any instant of time, the flying arrow “occupies a space equal to itself.” That is, the arrow at an instant cannot be moving, for motion takes a period of time, and a temporal instant is conceived as a point, not itself having duration. It follows that the arrow is at rest at every instant, and so does not move. What goes for arrows goes for everything: nothing moves. Scholars disagree about what Zeno himself took his paradoxes to show. There is no evidence that he offered any “solutions” to them. One view is that they were part of a program to establish that multiplicity is an illusion, and that reality is a seamless whole. The argument could be reconstructed like this: if you allow that reality can be successively divided into parts, you find yourself with these insupportable paradoxes; so you must think of reality as a single indivisible One.  Refs.: H.

sensus: sensationalism, the belief that all mental states  particularly cognitive states  are derived, by composition or association, from sensation. It is often joined to the view that sensations provide the only evidence for our beliefs, or more rarely to the view that statements about the world can be reduced, without loss, to statements about sensation. Hobbes was the first important sensationalist in modern times. “There is no conception in man’s mind,” he wrote, “which hath not at first, totally, or by parts, been begotten upon the organs of sense. The rest are derived from that original.” But the belief gained prominence in the eighteenth century, due largely to the influence of Locke. Locke himself was not a sensationalist, because he took the mind’s reflection on its own operations to be an independent source of ideas. But his distinction between simple and complex ideas was used by eighteenthcentury sensationalists such as Condillac and Hartley to explain how conceptions that seem distant from sense might nonetheless be derived from it. And to account for the particular ways in which simple ideas are in fact combined, Condillac and Hartley appealed to a second device described by Locke: the association of ideas. “Elementary” sensations  the building blocks of our mental life  were held by the sensationalists to be non-voluntary, independent of judgment, free of interpretation, discrete or atomic, and infallibly known. Nineteenth-century sensationalists tried to account for perception in terms of such building blocks; they struggled particularly with the perception of space and time. Late nineteenth-century critics such as Ward and James advanced powerful arguments against the reduction of perception to sensation. Perception, they claimed, involves more than the passive reception or recombination and association of discrete pellets of incorrigible information. They urged a change in perspective  to a functionalist viewpoint more closely allied with prevailing trends in biology  from which sensationalism never fully recovered.  sensibile: Austin, “Sense and sensibile,” as used by Russell, those entities that no one is at the moment perceptually aware of, but that are, in every other respect, just like the objects of perceptual awareness. If one is a direct realist and believes that the objects one is aware of in sense perception are ordinary physical objects, then sensibilia are, of course, just physical objects of which no one is at the moment aware. Assuming with common sense that ordinary objects continue to exist when no one is aware of them, it follows that sensibilia exist. If, however, one believes as Russell did that what one is aware of in ordinary sense perception is some kind of idea in the mind, a so-called sense-datum, then sensibilia have a problematic status. A sensibile then turns out to be an unsensed sense-datum. On some the usual conceptions of sense-data, this is like an unfelt pain, since a sense-datum’s existence not as a sense-datum, but as anything at all depends on our someone’s perception of it. To exist for such things is to be perceived see Berkeley’s “esse est percipii“. If, however, one extends the notion of sense-datum as Moore was inclined to do to whatever it is of which one is directly aware in sense perception, then sensibilia may or may not exist. It depends on what  physical objects or ideas in the mind  we are directly aware of in sense perception and, of course, on the empirical facts about whether objects continue to exist when they are not being perceived. If direct realists are right, horses and trees, when unobserved, are sensibilia. So are the front surfaces of horses and trees things Moore once considered to be sensedata. If the direct realists are wrong, and what we are perceptually aware of are “ideas in the mind,” then whether or not sensibilia exist depends on whether or not such ideas can exist apart from any mind.  sensorium, the seat and cause of sensation in the brain of humans and other animals. The term is not part of contemporary psychological parlance; it belongs to prebehavioral, prescientific psychology, especially of the seventeenth and eighteenth centuries. Only creatures possessed of a sensorium were thought capable of bodily and perceptual sensations. Some thinkers believed that the sensorium, when excited, also produced muscular activity and motion. sensus communis, a cognitive faculty to which the five senses report. It was first argued for in Aristotle’s On the Soul II.12, though the term ‘common sense’ was first introduced in Scholastic thought. Aristotle refers to properties such as magnitude that are perceived by more than one sense as common sensibles. To recognize common sensibles, he claims, we must possess a single cognitive power to compare such qualities, received from the different senses, to one another. Augustine says the “inner sense” judges whether the senses are working properly, and perceives whether the animal perceives De libero arbitrio II.35. Aquinas In De anima II, 13.370 held that it is also by the common sense that we perceive we live. He says the common sense uses the external senses to know sensible forms, preparing the sensible species it receives for the operation of the cognitive power, which recognizes the real thing causing the sensible species.  sentential connective, also called sentential operator, propositional connective, propositional operator, a word or phrase, such as ‘and’, ‘or’, or ‘if . . . then’, that is used to construct compound sentences from atomic  i.e., non-compound  sentences. A sentential connective can be defined formally as an expression containing blanks, such that when the blanks are replaced with sentences the result is a compound sentence. Thus, ‘if ——— then ———’ and ‘——— or ———’ are sentential connectives, since we can replace the blanks with sentences to get the compound sentences ‘If the sky is clear then we can go swimming’ and ‘We can go swimming or we can stay home’. Classical logic makes use of truth-functional connectives only, for which the truth-value of the compound sentence can be determined uniquely by the truth-value of the sentences that replace the blanks. The standard truth-functional sensibilia sentential connective 834    834 connectives are ‘and’, ‘or’, ‘not’, ‘if . . . then’, and ‘if and only if’. There are many non-truth-functional connectives as well, such as ‘it is possible that ———’ and ‘——— because ———’.  sentimentalism, the theory, prominent in the eighteenth century, that epistemological or moral relations are derived from feelings. Although sentimentalism and sensationalism are both empiricist positions, the latter view has all knowledge built up from sensations, experiences impinging on the senses. Sentimentalists may allow that ideas derive from sensations, but hold that some relations between them are derived internally, that is, from sentiments arising upon reflection. Moral sentimentalists, such as Shaftesbury, Hutcheson, and Hume, argued that the virtue or vice of a character trait is established by approving or disapproving sentiments. Hume, the most thoroughgoing sentimentalist, also argued that all beliefs about the world depend on sentiments. On his analysis, when we form a belief, we rely on the mind’s causally connecting two experiences, e.g., fire and heat. But, he notes, such causal connections depend on the notion of necessity  that the two perceptions will always be so conjoined  and there is nothing in the perceptions themselves that supplies that notion. The idea of necessary connection is instead derived from a sentiment: our feeling of expectation of the one experience upon the other. Likewise, our notions of substance the unity of experiences in an object and of self the unity of experiences in a subject are sentimentbased. But whereas moral sentiments do not purport to represent the external world, these metaphysical notions of necessity, substance, and self are “fictions,” creations of the imagination purporting to represent something in the outside world.

sententia: For some reason, perhaps of his eccentricity, J. L. Austin was in love with Chomsky. He would read “Syntactic Structures” aloud to the Play Group. And Grice was listening. This stuck with Grice, who started to use ‘sentence,’ even in Polish, when translating Tarski. Hardie had taught him that ‘sententia’ was a Roman transliteration of ‘dia-noia,’ which helped. Since “Not when the the of dog” is NOT a sentence, not even an ‘ill-formed sentence,’ Grice concludes that like ‘reason,’ and ‘cabbage,’ sentence is a value-paradeigmatic concept. His favourite sentence was “Fido is shaggy,” uttered to communicate that Smith’s dog is hairy coated. One of Grice’s favourite sentences was Carnap’s “Pirots karulise elatically,” which Carnap borrowed from (but never returned to) Baron Russell. (“I later found out a ‘pirot’ is an extinct fish, which destroyed my whole implicaturum – talk of ichthyological necessity!” (Carnap contrasted, “Pirots karulise elatically,” with “The not not if not the dog the.”

shared experience: WoW: 286. Grice was fascinated by the etymology of ‘share,’ – “which is so difficult to translate to Grecian!” – “Co-operation can be regarded as a shared experience. You cooperate not just when you help, but, as the name indicates, when you operate along with another – when you SHARE some task – in this case influencing the other in the dyad, and being influenced by him.”

set: “Is the idea of a one-member set implicatural?” – Grice. “I distinguish between a class and a set, but Strawson does not.” – Grice --  the study of collections, ranging from familiar examples like a set of encyclopedias or a deck of cards to mathematical examples like the set of natural numbers or the set of points on a line or the set of functions from a set A to another set B. Sets can be specified in two basic ways: by a list e.g., {0, 2, 4, 6, 8} and as the extension of a property e.g., {x _ x is an even natural number less than 10}, where this is read ‘the set of all x such that x is an even natural number less than 10’. The most fundamental relation in set theory is membership, as in ‘2 is a member of the set of even natural numbers’ in symbols: 2 1 {x _ x is an even natural number}. Membership is determinate, i.e., any candidate for membership in a given set is either in the set or not in the set, with no room for vagueness or ambiguity. A set’s identity is completely determined by its members or elements i.e., sets are extensional rather than intensional. Thus {x _ x is human} is the same set as {x _ x is a featherless biped} because they have the same members. The smallest set possible is the empty or null set, the set with no members. There cannot be more than one empty set, by extensionality. It can be specified, e.g., as {x _ x & x}, but it is most often symbolized as / or { }. A set A is called a subset of a set B and B a superset of A if every member of A is also a member of B; in symbols, A 0 B. So, the set of even natural numbers is a subset of the set of all natural numbers, and any set is a superset of the empty set. The union of two sets A and B is the set whose members are the members of A and the members of B  in symbols, A 4 B % {x _ x 1 A or x 1 B}  so the union of the set of even natural numbers and the set of odd natural numbers is the set of all natural numbers. The intersection of two sets A and B is the set whose members are common to both A and B  in symbols, A 3 B % {x _ x 1 A and x 1 B}  so the intersection of the set of even natural numbers and the set of prime natural numbers is the singleton set {2}, whose only member is the number 2. Two sets whose intersection is empty are called disjoint, e.g., the set of even natural numbers and the set of odd natural numbers. Finally, the difference between a set A and a set B is the set whose members are members of A but not members of B  in symbols, A  B % {x _ x 1 A and x 2 B}  so the set of odd numbers between 5 and 20 minus the set of prime natural numbers is {9, 15}. By extensionality, the order in which the members of a set are listed is unimportant, i.e., {1, 2, 3} % {2, 3, 1}. To introduce the concept of ordering, we need the notion of the ordered pair of a and b  in symbols, a, b or . All that is essential to ordered pairs is that two of them are equal only when their first entries are equal and their second entries are equal. Various sets can be used to simulate this behavior, but the version most commonly used is the Kuratowski ordered pair: a, b is defined to be {{a}, {a, b}}. On this definition, it can indeed be proved that a, b % c, d if and only if a % c and b % d. The Cartesian product of two sets A and B is the set of all ordered pairs whose first entry is in A and whose second entry is B  in symbols, A $ B % {x _ x % a, b for some a 1 A and some b 1 B}. This set-theoretic reflection principles set theory 836    836 same technique can be used to form ordered triples  a, b, c % a, b, c; ordered fourtuples  a, b, c, d % a, b, c, d; and by extension, ordered n-tuples for all finite n. Using only these simple building blocks, substitutes for all the objects of classical mathematics can be constructed inside set theory. For example, a relation is defined as a set of ordered pairs  so the successor relation among natural numbers becomes {0, 1, 1, 2, 2, 3 . . . }  and a function is a relation containing no distinct ordered pairs of the form a, b and a, c  so the successor relation is a function. The natural numbers themselves can be identified with various sequences of sets, the most common of which are finite von Neumann ordinal numbers: /, {/}, {/, {/}, {/}, {/}, {/, {/}}}, . . . . On this definition, 0 % /, 1 % {/}, 2 % {/, {/}}, etc., each number n has n members, the successor of n is n 4 {n}, and n ‹ m if and only if n 1 m. Addition and multiplication can be defined for these numbers, and the Peano axioms proved from the axioms of set theory; see below. Negative, rational, real, and complex numbers, geometric spaces, and more esoteric mathematical objects can all be identified with sets, and the standard theorems about them proved. In this sense, set theory provides a foundation for mathematics. Historically, the theory of sets arose in the late nineteenth century. In his work on the foundations of arithmetic, Frege identified the natural numbers with the extensions of certain concepts; e.g., the number two is the set of all concepts C under which two things fall  in symbols, 2 % {x _ x is a concept, and there are distinct things a and b which fall under x, and anything that falls under x is either a or b}. Cantor was led to consider complex sets of points in the pursuit of a question in the theory of trigonometric series. To describe the properties of these sets, Cantor introduced infinite ordinal numbers after the finite ordinals described above. The first of these, w, is {0, 1, 2, . . .}, now understood in von Neumann’s terms as the set of all finite ordinals. After w, the successor function yields w ! 1 % w 4 {w} % {0, 1, 2, . . . n, n + 1, . . . , w}, then w ! 2 % w ! 1 ! 1 % {0, 1, 2, . . . , w , w ! 1}, w ! 3 % w ! 2 ! 1 % {0, 1, 2, . . . , w, w ! 1, w ! 2}, and so on; after all these comes w ! w % {0, 1, 2, . . . , w, w ! 1, w ! 2, . . . , w ! n, w ! n ! 1, . . .}, and the process begins again. The ordinal numbers are designed to label the positions in an ordering. Consider, e.g., a reordering of the natural numbers in which the odd numbers are placed after the evens: 0, 2, 4, 6, . . . 1, 3, 5, 7, . . . . The number 4 is in the third position of this sequence, and the number 5 is in the w + 2nd. But finite numbers also perform a cardinal function; they tell us how many so-andso’s there are. Here the infinite ordinals are less effective. The natural numbers in their usual order have the same structure as w, but when they are ordered as above, with the evens before the odds, they take on the structure of a much larger ordinal, w ! w. But the answer to the question, How many natural numbers are there? should be the same no matter how they are arranged. Thus, the transfinite ordinals do not provide a stable measure of the size of an infinite set. When are two infinite sets of the same size? On the one hand, the infinite set of even natural numbers seems clearly smaller than the set of all natural numbers; on the other hand, these two sets can be brought into one-to-one correspondence via the mapping that matches 0 to 0, 1 to 2, 2 to 4, 3 to 6, and in general, n to 2n. This puzzle had troubled mathematicians as far back as Galileo, but Cantor took the existence of a oneto-one correspondence between two sets A and B as the definition of ‘A is the same size as B’. This coincides with our usual understanding for finite sets, and it implies that the set of even natural numbers and the set of all natural numbers and w ! 1 and w! 2 and w ! w and w ! w and many more all have the same size. Such infinite sets are called countable, and the number of their elements, the first infinite cardinal number, is F0. Cantor also showed that the set of all subsets of a set A has a size larger than A itself, so there are infinite cardinals greater than F0, namely F1, F2, and so on. Unfortunately, the early set theories were prone to paradoxes. The most famous of these, Russell’s paradox, arises from consideration of the set R of all sets that are not members of themselves: is R 1 R? If it is, it isn’t, and if it isn’t, it is. The Burali-Forti paradox involves the set W of all ordinals: W itself qualifies as an ordinal, so W 1 W, i.e., W ‹ W. Similar difficulties surface with the set of all cardinal numbers and the set of all sets. At fault in all these cases is a seemingly innocuous principle of unlimited comprehension: for any property P, there is a set {x _ x has P}. Just after the turn of the century, Zermelo undertook to systematize set theory by codifying its practice in a series of axioms from which the known derivations of the paradoxes could not be carried out. He proposed the axioms of extensionality two sets with the same members are the same; pairing for any a and b, there is a set {a, b}; separation for any set A and property P, there is a set {x _ x 1 A and x has P}; power set for any set A, there is a set {x _ x0 A}; union for any set of sets F, there is a set {x _ x 1 A for some A 1 F}  this yields A 4 B, when F % {A, B} and {A, B} comes from A and B by pairing; infinity w exists; and choice for any set of non-empty sets, there is a set that contains exactly one member from each. The axiom of choice has a vast number of equivalents, including the well-ordering theorem  every set can be well-ordered  and Zorn’s lemma  if every chain in a partially ordered set has an upper bound, then the set has a maximal element. The axiom of separation limits that of unlimited comprehension by requiring a previously given set A from which members are separated by the property P; thus troublesome sets like Russell’s that attempt to collect absolutely all things with P cannot be formed. The most controversial of Zermelo’s axioms at the time was that of choice, because it posits the existence of a choice set  a set that “chooses” one from each of possibly infinitely many non-empty sets  without giving any rule for making the choices. For various philosophical and practical reasons, it is now accepted without much debate. Fraenkel and Skolem later formalized the axiom of replacement if A is a set, and every member a of A is replaced by some b, then there is a set containing all the b’s, and Skolem made both replacement and separation more precise by expressing them as schemata of first-order logic. The final axiom of the contemporary theory is foundation, which guarantees that sets are formed in a series of stages called the iterative hierarchy begin with some non-sets, then form all possible sets of these, then form all possible sets of the things formed so far, then form all possible sets of these, and so on. This iterative picture of sets built up in stages contrasts with the older notion of the extension of a concept; these are sometimes called the mathematical and the logical notions of collection, respectively. The early controversy over the paradoxes and the axiom of choice can be traced to the lack of a clear distinction between these at the time. Zermelo’s first five axioms all but choice plus foundation form a system usually called Z; ZC is Z with choice added. Z plus replacement is ZF, for Zermelo-Fraenkel, and adding choice makes ZFC, the theory of sets in most widespread use today. The consistency of ZFC cannot be proved by standard mathematical means, but decades of experience with the system and the strong intuitive picture provided by the iterative conception suggest that it is. Though ZFC is strong enough for all standard mathematics, it is not enough to answer some natural set-theoretic questions e.g., the continuum problem. This has led to a search for new axioms, such as large cardinal assumptions, but no consensus on these additional principles has yet been reached. Then there are the set-theoretica paradoxes, a collection of paradoxes that reveal difficulties in certain central notions of set theory. The best-known of these are Russell’s paradox, Burali-Forti’s paradox, and Cantor’s paradox. Russell’s paradox, discovered in 1 by Bertrand Russell, is the simplest and so most problematic of the set-theoretic paradoxes. Using it, we can derive a contradiction directly from Cantor’s unrestricted comprehension schema. This schema asserts that for any formula Px containing x as a free variable, there is a set {x _ Px} whose members are exactly those objects that satisfy Px. To derive the contradiction, take Px to be the formula x 1 x, and let z be the set {x _ x 2 x} whose existence is guaranteed by the comprehension schema. Thus z is the set whose members are exactly those objects that are not members of themselves. We now ask whether z is, itself, a member of z. If the answer is yes, then we can conclude that z must satisfy the criterion of membership in z, i.e., z must not be a member of z. But if the answer is no, then since z is not a member of itself, it satisfies the criterion for membership in z, and so z is a member of z. All modern axiomatizations of set theory avoid Russell’s paradox by restricting the principles that assert the existence of sets. The simplest restriction replaces unrestricted comprehension with the separation schema. Separation asserts that, given any set A and formula Px, there is a set {x 1 A _ Px}, whose members are exactly those members of A that satisfy Px. If we now take Px to be the formula x 2 x, then separation guarantees the existence of a set zA % {x 1 A _ x 2 x}. We can then use Russell’s reasoning to prove the result that zA cannot be a member of the original set A. If it were a member of A, then we could prove that it is a member of itself if and only if it is not a member of itself. Hence it is not a member of A. But this result is not problematic, and so the paradox is avoided. The Burali-Forte paradox and Cantor’s paradox are sometimes known as paradoxes of size, since they show that some collections are too large to be considered sets. The Burali-Forte paradox, discovered by Cesare Burali-Forte, is concerned with the set of all ordinal numbers. In Cantor’s set theory, an ordinal number can be assigned to any well-ordered set. A set is wellordered if every subset of the set has a least element. But Cantor’s set theory also guarantees the existence of the set of all ordinals, again due to the unrestricted comprehension schema. This set of ordinals is well-ordered, and so can be associated with an ordinal number. But it can be shown that the associated ordinal is greater than any ordinal in the set, hence greater than any ordinal number. Cantor’s paradox involves the cardinality of the set of all sets. Cardinality is another notion of size used in set theory: a set A is said to have greater cardinality than a set B if and only if B can be mapped one-to-one onto a subset of A but A cannot be so mapped onto B or any of its subsets. One of Cantor’s fundamental results was that the set of all subsets of a set A known as the power set of A has greater cardinality than the set A. Applying this result to the set V of all sets, we can conclude that the power set of V has greater cardinality than V. But every set in the power set of V is also in V since V contains all sets, and so the power set of V cannot have greater cardinality than V. We thus have a contradiction. Like Russell’s paradox, both of these paradoxes result from the unrestricted comprehension schema, and are avoided by replacing it with weaker set-existence principles. Various principles stronger than the separation schema are needed to get a reasonable set theory, and many alternative axiomatizations have been proposed. But the lesson of these paradoxes is that no setexistence principle can entail the existence of the Russell set, the set of all ordinals, or the set of all sets, on pain of contradiction. 

sextus empiricus: the sixth son of Empiricus the Elder – “My five brothers were not philosophers” -- Grecian Skeptic philosopher whose writings are the chief source of our knowledge about the extreme Skeptic view, Pyrrhonism. Practically nothing is known about him as a person. He was apparently a medical doctor and a teacher in a Skeptical school, probably in Alexandria. What has survived are his Hypotoposes, Outlines of Pyrrhonism, and a series of Skeptical critiques, Against the Dogmatists, questioning the premises and conclusions in many disciplines, such as physics, mathematics, rhetoric, and ethics. In these works, Sextus summarized and organized the views of Skeptical arguers before him. The Outlines starts with an attempt to indicate what Skepticism is, to explain the terminology employed by the Skeptics, how Pyrrhonian Skepticism differs from other so-called Skeptical views, and how the usual answers to Skepticism are rebutted. Sextus points out that the main Hellenistic philosophies, Stoicism, Epicureanism, and Academic Skepticism which is presented as a negative dogmatism, claimed that they would bring the adherent peace of mind, ataraxia. Unfortunately the dogmatic adherent would only become more perturbed by seeing the Skeptical objections that could be brought against his or her view. Then, by suspending judgment, epoche, one would find the tranquillity being sought. Pyrrhonian Skepticism is a kind of mental hygiene or therapy that cures one of dogmatism or rashness. It is like a purge that cleans out foul matter as well as itself. To bring about this state of affairs there are sets of Skeptical arguments that should bring one to suspense of judgment. The first set are the ten tropes of the earlier Skeptic, Anesidemus. The next are the five tropes about causality. And lastly are the tropes about the criterion of knowledge. The ten tropes stress the variability of sense experience among men and animals, among men, and within one individual. The varying and conflicting experiences present conflicts about what the perceived object is like. Any attempt to judge beyond appearances, to ascertain that which is non-evident, requires some way of choosing what data to accept. This requires a criterion. Since there is disagreement about what criterion to employ, we need a criterion of a criterion, and so on. Either we accept an arbitrary criterion or we get into an infinite regress. Similarly if we try to prove anything, we need a criterion of what constitutes a proof. If we offer a proof of a theory of proof, this will be circular reasoning, or end up in another infinite regress. Sextus devotes most of his discussion to challenging Stoic logic, which claimed that evident signs could reveal what is non-evident. There might be signs that suggested what is temporarily non-evident, such as smoke indicating that there is a fire, but any supposed linkage between evident signs and what is non-evident can be challenged and questioned. Sextus then applies the groups of Skeptical arguments to various specific subjects  physics, mathematics, music, grammar, ethics  showing that one should suspend judgment on any knowledge claims in these areas. Sextus denies that he is saying any of this dogmatically: he is just stating how he feels at given moments. He hopes that dogmatists sick with a disease, rashness, will be cured and led to tranquillity no matter how good or bad the Skeptical arguments might be.

shaftesbury, Lord, in full, Third Earl of Shaftesbury, title of Anthony Ashley Cooper, English philosopher and politician who originated the moral sense theory. He was born at Wimborne St. Giles, Dorsetshire. As a Country Whig he served in the House of Commons for three years and later, as earl, monitored meetings of the House of Lords. Shaftesbury introduced into British moral philosophy the notion of a moral sense, a mental faculty unique to human beings, involving reflection and feeling and constituting their ability to discern right and wrong. He sometimes represents the moral sense as analogous to a purported aesthetic sense, a special capacity by which we perceive, through our emotions, the proportions and harmonies of which, on his Platonic view, beauty is composed. For Shaftesbury, every creature has a “private good or interest,” an end to which it is naturally disposed by its constitution. But there are other goods as well  notably, the public good and the good without qualification of a sentient being. An individual creature’s goodness is defined by the tendency of its “natural affections” to contribute to the “universal system” of nature of which it is a part  i.e., their tendency to promote the public good. Because human beings can reflect on actions and affections, including their own and others’, they experience emotional responses not only to physical stimuli but to these mental objects as well e.g., to the thought of one’s compassion or kindness. Thus, they are capable of perceiving  and acquiring through their actions  a particular species of goodness, namely, virtue. In the virtuous person, the person of integrity, natural appetites and affections are in harmony with each other wherein lies her private good and in harmony with the public interest. Shaftesbury’s attempted reconciliation of selflove and benevolence is in part a response to the egoism of Hobbes, who argued that everyone is in fact motivated by self-interest. His defining morality in terms of psychological and public harmony is also a reaction to the divine voluntarism of his former tutor, Locke, who held that the laws of nature and morality issue from the will of God. On Shaftesbury’s view, morality exists independently of religion, but belief in God serves to produce the highest degree of virtue by nurturing a love for the universal system. Shaftesbury’s theory led to a general refinement of eighteenth-century ideas about moral feelings; a theory of the moral sense emerged, whereby sentiments are  under certain conditions  perceptions of, or constitutive of, right and wrong. In addition to several essays collected in three volumes under the title Characteristics of Men, Manners, Opinions, Times second edition, 1714, Shaftesbury also wrote stoical moral and religious meditations reminiscent of Epictetus and Marcus Aurelius. His ideas on moral sentiments exercised considerable influence on the ethical theories of Hutcheson and Hume, who later worked out in detail their own accounts of the moral sense.  H. P. Grice, “My favourite Cooper.”

sheffer stroke – see abdicatum, Grice, “Negation and privation” and “Lectures on negation” -- also called alternative denial, a binary truth-functor represented by the symbol ‘_’, the logical force of which can be expressed contextually in terms of ‘-’ and ‘&’ by the following definition: p_q % Df -p & q. The importance of the Sheffer stroke lies in the fact that it by itself can express any well-formed expression of truth-functional logic. Thus, since {-,7} forms an expressively complete set, defining -p as p_p and p 7 q as p_p _q_q provides for the possibility of a further reduction of primitive functors to one. This system of symbols is commonly called the stroke notation.

shyreswood: “I prefer the spelling shyreswood, since it SAYS what ‘sherwood’ merely implicates.” -- Sherwood, William, also called William Shyreswood, English logician who taught logic at Oxford and at Paris between 1235 and 1250. He was the earliest of the three great “summulist” writers, the other two whom he influenced strongly being Peter of Spain and Lambert of Auxerre. His main works are “Introductiones in Logicam,” “Syncategoremata,” “De insolubilibus,” and “Obligationes.” Some serious doubts have recently arisen about the authorship of the latter work. Since M. Grabmann published Sherwood’s Introductiones, philosophers have paid considerable attention to this seminal Griceian. While the first part of Introductiones offer the basic ideas of Aristotle’s Organon, and the latter part neatly lays out the Sophistical Refutations, the final tract expounds the doctrine of the four properties of a term. First, signification. Second, supposition. Third, conjunction, Fourth, appellation -- hence the label ‘terminist’ for this sort of logic. These logico-semantic discussions, together with the discussions of syncategorematic words, constitute the “logica moderna,” (Grice’s ‘mdoernism’) as opposed to the more strictly Aristotelian contents of the earlier logica vetus (Grice’s neo-traditionalism) and logica nova (“It took me quite a while to explain to Strawson the distinction between ‘logica nova’ and ‘logica moderna,’ only to have him tell me, “worry not, Grice – I’ll be into ‘logica vetus’ anyways!””. The doctrine of properties of terms and the analysis of syncategorematic terms, especially those of ‘all’ (or every) ‘no’ (or not or it is not the case) and ‘nothing’, ‘only’, ‘not’, ‘begins’ and ‘ceases (to eat iron) ‘necessarily’, ‘if’ (Latin ‘si,’ Grecian ‘ei’), ‘and’ (Latin ‘et’, Grecian ‘kai’) and ‘or’ (Latin ‘vel’)  may be said to constitute Sherwood’s or Shyrewood’s philosophy of logic. Shyrewood not only distinguishes categorematic descriptive and syncategorematic logical words but also shows how some terms are used categorematically in some contexts and syncategorematically in others – “he doesn’t explain which, and that’s one big map in his opus.”– Grice. He recognizes the importance of the order of words (hence Grice, ‘be orderly’) and of the scope of logical functors; he also anticipates the variety of composite and divided senses of propositions. Obligationes, if indeed his, attempts to state conditions under which a formal disputation may take place. De Insolubilibus deals with paradoxes of self-reference and with ways of solving them. Understanding Sherwood’s logic is important for understanding the later medieval developments of logica moderna down to Occam whom Grice laughed at (“modified Occam’s razor.”).
