semantics – Grice, “Mathematics and the synthetic a priorir,” Grice on Warnock’s Oxford readings in philosophy, ‘The philosophy of mathematics,’ Austin on Frege’s arithmetic -- philosophical geometer, philosophical mathematician –  H. P. Grice, “ΑΓΕΩΜΕΤΡΗΤΟΣ ΜΗΔΕΙΣ ΕΙΣΙΤΩ; or, The school of Plato.”  philosophy of mathematics, the study of ontological and epistemological problems raised by the content and practice of mathematics. The present agenda in this field evolved from critical developments, notably the collapse of Pythagoreanism, the development of modern calculus, and an early twentieth-century foundational crisis, which forced mathematicians and philosophers to examine mathematical methods and presuppositions. Grecian mathematics. The Pythagoreans, who represented the height of early demonstrative Grecian mathematics, believed that all scientific relations were measureable by natural numbers 1, 2, 3, etc. or ratios of natural numbers, and thus they assumed discrete, atomic units for the measurement of space, time, and motion. The discovery of irrational magnitudes scotched the first of these beliefs. Zeno’s paradoxes showed that the second was incompatible with the natural assumption that space and time are infinitely divisible. The Grecian reaction, ultimately codified in Euclid’s Elements, included Plato’s separation of mathematics from empirical science and, within mathematics, distinguished number theory  a study of discretely ordered entities  from geometry, which concerns continua. Following Aristotle and employing methods perfected by Eudoxus, Euclid’s proofs used only “potentially infinite” geometric and arithmetic procedures. The Elements’ axiomatic form and its constructive proofs set a standard for future mathematics. Moreover, its dependence on visual intuition whose consequent deductive gaps were already noted by Archimedes, together with the challenge of Euclid’s infamous fifth postulate about parallel lines, and the famous unsolved problems of compass and straightedge construction, established an agenda for generations of mathematicians. The calculus. The two millennia following Euclid saw new analytical tools e.g., Descartes’s geometry that wedded arithmetic and geometric considerations and toyed with infinitesimally small quantities. These, together with the demands of physical application, tempted mathematicians to abandon the pristine Grecian dichotomies. Matters came to a head with Newton’s and Leibniz’s almost simultaneous discovery of the powerful computational techniques of the calculus. While these unified physical science in an unprecedented way, their dependence on unclear notions of infinitesimal spatial and temporal increments emphasized their shaky philosophical foundation. Berkeley, for instance, condemned the calculus for its unintuitability. However, this time the power of the new methods inspired a decidedly conservative response. Kant, in particular, tried to anchor the new mathematics in intuition. Mathematicians, he claimed, construct their objects in the “pure intuitions” of space and time. And these mathematical objects are the a priori forms of transcendentally ideal empirical objects. For Kant this combination of epistemic empiricism and ontological idealism explained the physical applicability of mathematics and thus granted “objective validity” i.e., scientific legitimacy to mathematical procedures. Two nineteenth-century developments undercut this Kantian constructivism in favor of a more abstract conceptual picture of mathematics. First, Jànos Bolyai, Carl F. Gauss, Bernhard Riemann, Nikolai Lobachevsky, and others produced consistent non-Euclidean geometries, which undid the Kantian picture of a single a priori science of space, and once again opened a rift between pure mathematics and its physical applications. Second, Cantor and Dedekind defined the real numbers i.e., the elements of the continuum as infinite sets of rational and ultimately natural numbers. Thus they founded mathematics on the concepts of infinite set and natural number. Cantor’s set theory made the first concept rigorously mathematical; while Peano and Frege both of whom advocated securing rigor by using formal languages did that for the second. Peano axiomatized number theory, and Frege ontologically reduced the natural numbers to sets indeed sets that are the extensions of purely logical concepts. Frege’s Platonistic conception of numbers as unintuitable objects and his claim that mathematical truths follow analytically from purely logical definitions  the thesis of logicism  are both highly anti-Kantian. Foundational crisis and movements. But antiKantianism had its own problems. For one thing, Leopold Kronecker, who following Peter Dirichlet wanted mathematics reduced to arithmetic and no further, attacked Cantor’s abstract set theory on doctrinal grounds. Worse yet, the discovery of internal antinomies challenged the very consistency of abstract foundations. The most famous of these, Russell’s paradox the set of all sets that are not members of themselves both is and isn’t a member of itself, undermined Frege’s basic assumption that every well-formed concept has an extension. This was a full-scale crisis. To be sure, Russell himself together with Whitehead preserved the logicist foundational approach by organizing the universe of sets into a hierarchy of levels so that no set can be a member of itself. This is type theory. However, the crisis encouraged two explicitly Kantian foundational projects. The first, Hilbert’s Program, attempted to secure the “ideal” i.e., infinitary parts of mathematics by formalizing them and then proving the resultant formal systems to be conservative and hence consistent extensions of finitary theories. Since the proof itself was to use no reasoning more complicated than simple numerical calculations  finitary reasoning  the whole metamathematical project belonged to the untainted “contentual” part of mathematics. Finitary reasoning was supposed to update Kant’s intuition-based epistemology, and Hilbert’s consistency proofs mimic Kant’s notion of objective validity. The second project, Brouwer’s intuitionism, rejected formalization, and was not only epistemologically Kantian resting mathematical reasoning on the a priori intuition of time, but ontologically Kantian as well. For intuitionism generated both the natural and the real numbers by temporally ordered conscious acts. The reals, in particular, stem from choice sequences, which exploit Brouwer’s epistemic assumptions about the open future. These foundational movements ultimately failed. Type theory required ad hoc axioms to express the real numbers; Hilbert’s Program foundered on Gödel’s theorems; and intuitionism remained on the fringes because it rejected classical logic and standard mathematics. Nevertheless the legacy of these movements  their formal methods, indeed their philosophical agenda  still characterizes modern research on the ontology and epistemology of mathematics. Set theory, e.g. despite recent challenges from category theory, is the lingua franca of modern mathematics. And formal languages with their precise semantics are ubiquitous in technical and philosophical discussions. Indeed, even intuitionistic mathematics has been formalized, and Michael Dummett has recast its ontological idealism as a semantic antirealism that defines truth as warranted assertability. In a similar semantic vein, Paul Benacerraf proposed that the philosophical problem with Hilbert’s approach is inability to provide a uniform realistic i.e., referential, non-epistemic semantics for the allegedly ideal and contentual parts of mathematics; and the problem with Platonism is that its semantics makes its objects unknowable. Ontological issues. From this modern perspective, the simplest realism is the outright Platonism that attributes a standard model consisting of “independent” objects to classical theories expressed in a first-order language i.e., a language whose quantifiers range over objects but not properties. But in fact realism admits variations on each aspect. For one thing, the Löwenheim-Skolem theorem shows that formalized theories can have non-standard models. There are expansive non-standard models: Abraham Robinson, e.g., used infinitary non-standard models of Peano’s axioms to rigorously reintroduce infinitesimals. Roughly, an infinitesimal is the reciprocal of an infinite element in such a model. And there are also “constructive” models, whose objects must be explicitly definable. Predicative theories inspired by Poincaré and Hermann Weyl, whose stage-by-stage definitions refer only to previously defined objects, produce one variety of such models. Gödel’s constructive universe, which uses less restricted definitions to model apparently non-constructive axioms like the axiom of choice, exemplifies another variety. But there are also views various forms of structuralism which deny that formal theories have unique standard models at all. These views  inspired by the fact, already sensed by Dedekind, that there are multiple equivalid realizations of formal arithmetic  allow a mathematical theory to characterize only a broad family of models and deny unique reference to mathematical terms. Finally, some realistic approaches advocate formalization in secondorder languages, and some eschew ordinary semantics altogether in favor of substitutional quantification. These latter are still realistic, for they still distinguish truth from knowledge. Strict finitists  inspired by Vitters’s more stringent epistemic constraints  reject even the open-futured objects admitted by Brouwer, and countenance only finite or even only “feasible” objects. In the other direction, A. A. Markov and his school in Russia introduced a syntactic notion of algorithm from which they developed the field of “constructive analysis.” And the  mathematician Errett Bishop, starting from a Brouwer-like disenchantment with mathematical realism and with strictly formal approaches, recovered large parts of classical analysis within a non-formal constructive framework. All of these approaches assume abstract i.e., causally isolated mathematical objects, and thus they have difficulty explaining the wide applicability of mathematics constructive or otherwise within empirical science. One response, Quine’s “indispensability” view, integrates mathematical theories into the general network of empirical science. For Quine, mathematical objects  just like ordinary physical objects  exist simply in virtue of being referents for terms in our best scientific theory. By contrast Hartry Field, who denies that any abstract objects exist, also denies that any purely mathematical assertions are literally true. Field attempts to recast physical science in a relational language without mathematical terms and then use Hilbert-style conservative extension results to explain the evident utility of abstract mathematics. Hilary Putnam and Charles Parsons have each suggested views according to which mathematics has no objects proper to itself, but rather concerns only the possibilities of physical constructions. Recently, Geoffrey Hellman has combined this modal approach with structuralism. Epistemological issues. The equivalence proved in the 0s of several different representations of computability to the reasoning representable in elementary formalized arithmetic led Alonzo Church to suggest that the notion of finitary reasoning had been precisely defined. Church’s thesis so named by Stephen Kleene inspired Georg Kreisel’s investigations in the 0s and 70s of the general conditions for rigorously analyzing other informal philosophical notions like semantic consequence, Brouwerian choice sequences, and the very notion of a set. Solomon Feferman has suggested more recently that this sort of piecemeal conceptual analysis is already present in mathematics; and that this rather than any global foundation is the true role of foundational research. In this spirit, the relative consistency arguments of modern proof theory a continuation of Hilbert’s Program provide information about the epistemic grounds of various mathematical theories. Thus, on the one hand, proofs that a seemingly problematic mathematical theory is a conservative extension of a more secure theory provide some epistemic support for the former. In the other direction, the fact that classical number theory is consistent relative to intuitionistic number theory shows contra Hilbert that his view of constructive reasoning must differ from that of the intuitionists. Gödel, who did not believe that mathematics required any ties to empirical perception, suggested nevertheless that we have a special nonsensory faculty of mathematical intuition that, when properly cultivated, can help us decide among formally independent propositions of set theory and other branches of mathematics. Charles Parsons, in contrast, has examined the place of perception-like intuition in mathematical reasoning. Parsons himself has investigated models of arithmetic and of set theory composed of quasi-concrete objects e.g., numerals and other signs. Others consistent with some of Parsons’s observations have given a Husserlstyle phenomenological analysis of mathematical intuition. Frege’s influence encouraged the logical positivists and other philosophers to view mathematical knowledge as analytic or conventional. Poincaré responded that the principle of mathematical induction could not be analytic, and Vitters also attacked this conventionalism. In recent years, various formal independence results and Quine’s attack on analyticity have encouraged philosophers and historians of mathematics to focus on cases of mathematical knowledge that do not stem from conceptual analysis or strict formal provability. Some writers notably Mark Steiner and Philip Kitcher emphasize the analogies between empirical and mathematical discovery. They stress such things as conceptual evolution in mathematics and instances of mathematical generalizations supported by individual cases. Kitcher, in particular, discusses the analogy between axiomatization in mathematics and theoretical unification. Penelope Maddy has investigated the intramathematical grounds underlying the acceptance of various axioms of set theory. More generally, Imre Lakatos argued that most mathematical progress stems from a concept-stretching process of conjecture, refutation, and proof. This view has spawned a historical debate about whether critical developments such as those mentioned above represent Kuhn-style revolutions or even crises, or whether they are natural conceptual advances in a uniformly growing science.  Semantics -- philosophical mathematics: Grice: “Not for nothing Plato’s academy motto was, “Lascite ogni non-geometria voi ch’entrate!” ΑΓΕΩΜΕΤΡΗΤΟΣ ΜΗΔΕΙΣ ΕΙΣΙΤΩ – “a-gemetretos medeis eiseto” Grice thought that “7 + 5 = 12” was either synthetic or analytic – “but hardly both”. Grice on real numbers -- continuum problem, an open question that arose in Cantor’s theory of infinite cardinal numbers. By definition, two sets have the same cardinal number if there is a one-to-one correspondence between them. For example, the function that sends 0 to 0, 1 to 2, 2 to 4, etc., shows that the set of even natural numbers has the same cardinal number as the set of all natural numbers, namely F0. That F0 is not the only infinite cardinal follows from Cantor’s theorem: the power set of any set i.e., the set of all its subsets has a greater cardinality than the set itself. So, e.g., the power set of the natural numbers, i.e., the set of all sets of natural numbers, has a cardinal number greater than F0. The first infinite number greater than F0 is F1; the next after that is F2, and so on. When arithmetical operations are extended into the infinite, the cardinal number of the power set of the natural numbers turns out to be 2F0. By Cantor’s theorem, 2F0 must be greater than F0; the conjecture that it is equal to F1 is Cantor’s continuum hypothesis in symbols, CH or 2F0 % F1. Since 2F0 is also the cardinality of the set of points on a continuous line, CH can also be stated in this form: any infinite set of points on a line can be brought into one-to-one correspondence either with the set of natural numbers or with the set of all points on the line. Cantor and others attempted to prove CH, without success. It later became clear, due to the work of Gödel and Cohen, that their failure was inevitable: the continuum hypothesis can neither be proved nor disproved from the axioms of set theory ZFC. The question of its truth or falsehood  the continuum problem  remains open.  Philosophical mathematics: Grice on “7 + 5 = 12” -- Dedekind, R. G. mathematician, one of the most important figures in the mathematical analysis of foundational questions that took place in the late nineteenth century. Philosophically, three things are interesting about Dedekind’s work: 1 the insistence that the fundamental numerical systems of mathematics must be developed independently of spatiotemporal or geometrical notions; 2 the insistence that the numbers systems rely on certain mental capacities fundamental to thought, in particular on the capacity of the mind to “create”; and 3 the recognition that this “creation” is “creation” according to certain key properties, properties that careful mathematical analysis reveals as essential to the subject matter. 1 is a concern Dedekind shared with Bolzano, Cantor, Frege, and Hilbert; 2 sets Dedekind apart from Frege; and 3 represents a distinctive shift toward the later axiomatic position of Hilbert and somewhat away from the concern with the individual nature of the central abstract mathematical objects which is a central concern of Frege. Much of Dedekind’s position is sketched in the Habilitationsrede of 1854, the procedure there being applied in outline to the extension of the positive whole numbers to the integers, and then to the rational field. However, the two works best known to philosophers are the monographs on irrational numbers Stetigkeit und irrationale Zahlen, 1872 and on natural numbers Was sind und was sollen die Zahlen?, 8, both of which pursue the procedure advocated in 1854. In both we find an “analysis” designed to uncover the essential properties involved, followed by a “synthesis” designed to show that there can be such systems, this then followed by a “creation” of objects possessing the properties and nothing more. In the 1872 work, Dedekind suggests that the essence of continuity in the reals is that whenever the line is divided into two halves by a cut, i.e., into two subsets A1 and A2 such that if p 1 A1 and q 1 A2, then p ‹ q and, if p 1 A1 and q ‹ p, then q 1 A1, and if p 1 A2 and q  p, then q 1 A2 as well, then there is real number r which “produces” this cut, i.e., such that A1 % {p; p ‹ r}, and A2 % {p: r m p}. The task is then to characterize the real numbers so that this is indeed true of them. Dedekind shows that, whereas the rationals themselves do not have this property, the collection of all cuts in the rationals does. Dedekind then “defines” the irrationals through this observation, not directly as the cuts in the rationals themselves, as was done later, but rather through the “creation” of “new irrational numbers” to correspond to those rational cuts not hitherto “produced” by a number. The 8 work starts from the notion of a “mapping” of one object onto another, which for Dedekind is necessary for all exact thought. Dedekind then develops the notion of a one-toone into mapping, which is then used to characterize infinity “Dedekind infinity”. Using the fundamental notion of a chain, Dedekind characterizes the notion of a “simply infinite system,” thus one that is isomorphic to the natural number sequence. Thus, he succeeds in the goal set out in the 1854 lecture: isolating precisely the characteristic properties of the natural number system. But do simply infinite systems, in particular the natural number system, exist? Dedekind now argues: Any infinite system must Dedekind, Richard Dedekind, Richard 210   210 contain a simply infinite system Theorem 72. Correspondingly, Dedekind sets out to prove that there are infinite systems Theorem 66, for which he uses an infamous argument reminiscent of Bolzano’s from thirty years earlier involving “my thought-world,” etc. It is generally agreed that the argument does not work, although it is important to remember Dedekind’s wish to demonstrate that since the numbers are to be free creations of the human mind, his proofs should rely only on the properties of the mental. The specific act of “creation,” however, comes in when Dedekind, starting from any simply infinite system, abstracts from the “particular properties” of this, claiming that what results is the simply infinite system of the natural numbers.  Philosophical mathematics -- mathematical analysis, also called standard analysis, the area of mathematics pertaining to the so-called real number system, i.e. the area that can be based on an axiom set whose intended interpretation (standard model) has the set of real numbers as its domain (universe of discourse). Thus analysis includes, among its many subbranches, elementary algebra, differential and integral calculus, differential equations, the calculus of variations, and measure theory. Analytic geometry involves the application of analysis to geometry. Analysis contains a large part of the mathematics used in mathematical physics. The real numbers, which are representable by the ending and unending decimals, are usefully construed as (or as corresponding to) distances measured, relative to an arbitrary unit length, positively to the right and negatively to the left of an arbitrarily fixed zero point along a geometrical straight line. In particular, the class of real numbers includes as increasingly comprehensive proper subclasses the natural numbers, the integers (positive, negative, and zero), the rational numbers (or fractions), and the algebraic numbers (such as the square root of two). Especially important is the presence in the class of real numbers of non-algebraic (or transcendental) irrational numbers such as pi. The set of real numbers includes arbitrarily small and arbitrarily large, finite quantities, while excluding infinitesimal and infinite quantities. Analysis, often conceived as the mathematics of continuous magnitude, contrasts with arithmetic (natural number theory), which is regarded as the mathematics of discrete magnitude. Analysis is often construed as involving not just the real numbers but also the imaginary (complex) numbers. Traditionally analysis is expressed in a second-order or higher-order language wherein its axiom set has categoricity; each of its models is isomorphic to (has the same structure as) the standard model. When analysis is carried out in a first-order language, as has been increasingly the case since the 1950s, categoricity is impossible and it has nonstandard mass noun mathematical analysis models in addition to its standard model. A nonstandard model of analysis is an interpretation not isomorphic to the standard model but nevertheless satisfying the axiom set. Some of the nonstandard models involve objects reminiscent of the much-despised “infinitesimals” that were essential to the Leibniz approach to calculus and that were subject to intense criticism by Berkeley and other philosophers and philosophically sensitive mathematicians. These non-standard models give rise to a new area of mathematics, non-standard analysis, within which the fallacious arguments used by Leibniz and other early analysts form the heuristic basis of new and entirely rigorous proofs. -- mathematical function, an operation that, when applied to an entity (set of entities) called its argument(s), yields an entity known as the value of the function for that argument(s). This operation can be expressed by a functional equation of the form y % f(x) such that a variable y is said to be a function of a variable x if corresponding to each value of x there is one and only one value of y. The x is called the independent variable (or argument of the function) and the y the dependent variable (or value of the function). (Some definitions consider the relation to be the function, not the dependent variable, and some definitions permit more than one value of y to correspond to a given value of x, as in x2 ! y2 % 4.) More abstractly, a function can be considered to be simply a special kind of relation (set of ordered pairs) that to any element in its domain relates exactly one element in its range. Such a function is said to be a one-to-one correspondence if and only if the set {x,y} elements of S and {z,y} elements of S jointly imply x % z. Consider, e.g., the function {(1,1), (2,4), (3,9), (4,16), (5,25), (6,36)}, each of whose members is of the form (x,x2) – the squaring function. Or consider the function {(0,1), (1,0)} – which we can call the negation function. In contrast, consider the function for exclusive alternation (as in you may have a beer or glass of wine, but not both). It is not a one-to-one correspondence. For, 0 is the value of (0,1) and of (1,0), and 1 is the value of (0,0) and of (1,1). If we think of a function as defined on the natural numbers – functions from Nn to N for various n (most commonly n % 1 or 2) – a partial function is a function from Nn to N whose domain is not necessarily the whole of Nn (e.g., not defined for all of the natural numbers). A total function from Nn to N is a function whose domain is the whole of Nn (e.g., all of the natural numbers). -- mathematical induction, a method of definition and a method of proof. A collection of objects can be defined inductively. All members of such a collection can be shown to have a property by an inductive proof. The natural numbers and the set of well-formed formulas of a formal language are familiar examples of sets given by inductive definition. Thus, the set of natural numbers is inductively defined as the smallest set, N, such that: (B) 0 is in N and (I) for any x in N the successor of x is in N. (B) is the basic clause and (I) the inductive clause of this definition. Or consider a propositional language built on negation and conjunction. We start with a denumerable class of atomic sentence symbols ATOM = {A1, A2, . . .}. Then we can define the set of well-formed formulas, WFF, as the smallest set of expressions such that: (B) every member of ATOM is in WFF and (I) if x is in WFF then (- x) is in WFF and if x and y are in WFF then (x & y) is in WFF. We show that all members of an inductively defined set have a property by showing that the members specified by the basis have that property and that the property is preserved by the induction. For example, we show that all WFFs have an even number of parentheses by showing (i) that all ATOMs have an even number of parentheses and (ii) that if x and y have an even number of parentheses then so do (- x) and (x & y). This shows that the set of WFFs with an even number of parentheses satisfies (B) and (I). The set of WFFs with an even number of parentheses must then be identical to WFF, since – by definition – WFF is the smallest set that satisfies (B) and (I). Ordinary proof by mathematical induction shows that all the natural numbers, or all members of some set with the order type of the natural numbers, share a property. Proof by transfinite induction, a more general form of proof by mathematical induction, shows that all members of some well-ordered set have a certain property. A set is well-ordered if and only if every non-empty subset of it has a least element. The natural numbers are well-ordered. It is a consequence of the axiom of choice that every set can be well-ordered. Suppose that a set, X, is well-ordered and that P is the subset of X whose mathematical constructivism mathematical induction 541 4065m-r.qxd 08/02/1999 7:42 AM Page 541 members have the property of interest. Suppose that it can be shown for any element x of X, if all members of X less that x are in P, then so is x. Then it follows by transfinite induction that all members of X have the property, that X % P. For if X did not coincide with P, then the set of elements of x not in P would be non-empty. Since X is well-ordered, this set would have a least element, x*. But then by definition, all members of X less than x* are in P, and by hypothesis x* must be in P after all.. -- mathematical intuitionism, a twentieth-century movement that reconstructs mathematics in accordance with an epistemological idealism and a Kantian metaphysics. Specifically, Brouwer, its founder, held that there are no unexperienced truths and that mathematical objects stem from the a priori form of those conscious acts which generate empirical objects. Unlike Kant, however, Brouwer rejected the apriority of space and based mathematics solely on a refined conception of the intuition of time. Intuitionistic mathematics. According to Brouwer, the simplest mathematical act is to distinguish between two diverse elements in the flow of consciousness. By repeating and concatenating such acts we generate each of the natural numbers, the standard arithmetical operations, and thus the rational numbers with their operations as well. Unfortunately, these simple, terminating processes cannot produce the convergent infinite sequences of rational numbers that are needed to generate the continuum (the nondenumerable set of real numbers, or of points on the line). Some “proto-intuitionists” admitted infinite sequences whose elements are determined by finitely describable rules. However, the set of all such algorithmic sequences is denumerable and thus can scarcely generate the continuum. Brouwer’s first attempt to circumvent this – by postulating a single intuition of an ever growing continuum – mirrored Aristotle’s picture of the continuum as a dynamic whole composed of inseparable parts. But this approach was incompatible with the set-theoretic framework that Brouwer accepted, and by 1918 he had replaced it with the concept of an infinite choice sequence. A choice sequence of rational numbers is, to be sure, generated by a “rule,” but the rule may leave room for some degree of freedom in choosing the successive elements. It might, e.g., simply require that the n ! 1st choice be a rational number that lies within 1/n of the nth choice. The set of real numbers generated by such semideterminate sequences is demonstrably non-denumerable. Following his epistemological beliefs, Brouwer admitted only those properties of a choice sequence which are determined by its rule and by a finite number of actual choices. He incorporated this restriction into his version of set theory and obtained a series of results that conflict with standard (classical) mathematics. Most famously, he proved that every function that is fully defined over an interval of real numbers is uniformly continuous. (Pictorially, the graph of the function has no gaps or jumps.) Interestingly, one corollary of this theorem is that the set of real numbers cannot be divided into mutually exclusive subsets, a property that rigorously recovers the Aristotelian picture of the continuum. The clash with classical mathematics. Unlike his disciple Arend Heyting, who considered intuitionistic and classical mathematics as separate and therefore compatible subjects, Brouwer viewed them as incompatible treatments of a single subject matter. He even occasionally accused classical mathematics of inconsistency at the places where it differed from intuitionism. This clash concerns the basic concept of what counts as a mathematical object. Intuitionism allows, and classical mathematics rejects, objects that may be indeterminate with respect to some of their properties. Logic and language. Because he believed that mathematical constructions occur in prelinguistic consciousness, Brouwer refused to limit mathematics by the expressive capacity of any language. Logic, he claimed, merely codifies already completed stages of mathematical reasoning. For instance, the principle of the excluded middle stems from an “observational period” during which mankind catalogued finite phenomena (with decidable properties); and he derided classical mathematics for inappropriately applying this principle to infinitary aspects of mathematics. Formalization. Brouwer’s views notwithstanding, in 1930 Heyting produced formal systems for intuitionistic logic (IL) and number theory. These inspired further formalizations (even of the theory of choice sequences) and a series of proof-theoretic, semantic, and algebraic studies that related intuitionistic and classical formal systems. Stephen Kleene, e.g., interpreted IL and other intuitionistic formal systems using the classical theory of recursive functions. Gödel, who showed that IL cannot coincide with any finite many-valued logic, demonstrated its relation to the modal logic, S4; and Kripke provided a formal semantics for IL similar to the possible worlds semantics for S4. For a while the study of intuitionistic formal systems used strongly classical methods, but since the 1970s intuitionistic methods have been employed as well. Meaning. Heyting’s formalization reflected a theory of meaning implicit in Brouwer’s epistemology and metaphysics, a theory that replaces the traditional correspondence notion of truth with the notion of constructive proof. More recently Michael Dummett has extended this to a warranted assertability theory of meaning for areas of discourse outside of mathematics. He has shown how assertabilism provides a strategy for combating realism about such things as physical objects, mental objects, and the past. -- mathematical structuralism, the view that the subject of any branch of mathematics is a structure or structures. The slogan is that mathematics is the science of structure. Define a “natural number system” to be a countably infinite collection of objects with one designated initial object and a successor relation that satisfies the principle of mathematical induction. Examples of natural number systems are the Arabic numerals and an infinite sequence of distinct moments of time. According to structuralism, arithmetic is about the form or structure common to natural number systems. Accordingly, a natural number is something like an office in an organization or a place in a pattern. Similarly, real analysis is about the real number structure, the form common to complete ordered fields. The philosophical issues concerning structuralism concern the nature of structures and their places. Since a structure is a one-over-many of sorts, it is something like a universal. Structuralists have defended analogues of some of the traditional positions on universals, such as realism and nominalism. Philosophical mathematics -- metamathematics, the study and establishment, by restricted (and, in particular, finitary) means, of the consistency or reliability of the various systems of classical mathematics. The term was apparently introduced, with pejorative overtones relating it to ‘metaphysics’, in the 1870s in connection with the discussion of non-Euclidean geometries. It was introduced in the sense given here, shorn of negative connotations, by Hilbert (see his “Neubegründung der Mathematik. Erste Mitteilung,” 1922), who also referred to it as Beweistheorie or proof theory. A few years later (specifically, in the 1930 papers “Über einige fundamentale Begriffe der Metamathematik” and “Fundamentale Begriffe der Methodologie der deduktiven Wissenschaften. I”) Tarski fitted it with a somewhat broader, less restricted sense: broader in that the scope of its concerns was increased to include not only questions of consistency, but also a host of other questions (e.g. questions of independence, completeness and axiomatizability) pertaining to what Tarski referred to as the “methodology of the deductive sciences” (which was his synonym for ‘metamathematics’); less restricted in that the standards of proof were relaxed so as to permit other than finitary – indeed, other than constructive – means. On this broader conception of Tarski’s, formalized deductive disciplines form the field of research of metamathematics roughly in the same sense in which spatial entities form the field of research in geometry or animals that of zoology. Disciplines, he said, are to be regarded as sets of sentences to be investigated from the point of view of their consistency, axiomatizability (of various types), completeness, and categoricity or degree of categoricity, etc. Eventually (see the 1935 and 1936 papers “Grundzüge des Systemenkalkül, Erster Teil” and “Grundzüge der Systemenkalkül, Zweiter Teil”) Tarski went on to include all manner of semantical questions among the concerns of metamathematics, thus diverging rather sharply from Hilbert’s original syntactical focus. Today, the terms ‘metatheory’ and ‘metalogic’ are used to signify that broad set of interests, embracing both syntactical and semantical studies of formal languages and systems, which Tarski came to include under the general heading of metamathematics. Those having to do specifically with semantics belong to that more specialized branch of modern logic known as model theory, while those dealing with purely syntactical questions belong to what has come to be known as proof theory (where this latter is now, however, permitted to employ other than finitary methods in the proofs of its theorems).

philosophical theology: Grice: “At Oxford, pretentious as they are, they like ‘divinity’ – there are doctors in divinity!” -- philosophy of religion, the subfield of philosophy devoted to the study of religious phenomena. Although religions are typically complex systems of theory and practice, including both myths and rituals, philosophers tend to concentrate on evaluating religious truth claims. In the major theistic traditions, Judaism, Christianity, and Islam, the most important of these claims concern the existence, nature, and activities of God. Such traditions commonly understand God to be something like a person who is disembodied, eternal, free, all-powerful, all-knowing, the creator and sustainer of the universe, and the proper object of human obedience and worship. One important question is whether this conception of the object of human religious activity is coherent; another is whether such a being actually exists. Philosophers of religion have sought rational answers to both questions. The major theistic traditions draw a distinction between religious truths that can be discovered and even known by unaided human reason and those to which humans have access only through a special divine disclosure or revelation. According to Aquinas, e.g., the existence of God and some things about the divine nature can be proved by unaided human reason, but such distinctively Christian doctrines as the Trinity and Incarnation cannot be thus proved and are known to humans only because God has revealed them. Theists disagree about how such divine disclosures occur; the main candidates for vehicles of revelation include religious experience, the teachings of an inspired religious leader, the sacred scriptures of a religious community, and the traditions of a particular church. The religious doctrines Christian traditions take to be the content of revelation are often described as matters of faith. To be sure, such traditions typically affirm that faith goes beyond mere doctrinal belief to include an attitude of profound trust in God. On most accounts, however, faith involves doctrinal belief, and so there is a contrast within the religious domain itself between faith and reason. One way to spell out the contrast  though not the only way  is to imagine that the content of revelation is divided into two parts. On the one hand, there are those doctrines, if any, that can be known by human reason but are also part of revelation; the existence of God is such a doctrine if it can be proved by human reason alone. Such doctrines might be accepted by some people on the basis of rational argument, while others, who lack rational proof, accept them on the authority of revelation. On the other hand, there are those doctrines that cannot be known by human reason and for which the authority of revelation is the sole basis. They are objects of faith rather than reason and are often described as mysteries of faith. Theists disagree about how such exclusive objects of faith are related to reason. One prominent view is that, although they go beyond reason, they are in harmony with it; another is that they are contrary to reason. Those who urge that such doctrines should be accepted despite the fact that, or even precisely because, they are contrary to reason are known as fideists; the famous slogan credo quia absurdum ‘I believe because it is absurd’ captures the flavor of extreme fideism. Many scholars regard Kierkegaard as a fideist on account of his emphasis on the paradoxical nature of the Christian doctrine that Jesus of Nazareth is God incarnate. Modern philosophers of religion have, for the most part, confined their attention to topics treatable without presupposing the truth of any particular tradition’s claims about revelation and have left the exploration of mysteries of faith to the theologians of various traditions. A great deal of philosophical work clarifying the concept of God has been prompted by puzzles that suggest some incoherence in the traditional concept. One kind of puzzle concerns the coherence of individual claims about the nature of God. Consider the traditional affirmation that God is allpowerful omnipotent. Reflection on this doctrine raises a famous question: Can God make a stone so heavy that even God cannot lift it? No matter how this is answered, it seems that there is at least one thing that even God cannot do, i.e., make such a stone or lift such a stone, and so it appears that even God cannot be all-powerful. Such puzzles stimulate attempts by philosophers to analyze the concept of omnipotence in a way that specifies more precisely the scope of the powers coherently attributable to an omnipotent being. To the extent that such attempts succeed, they foster a deeper understanding of the concept of God and, if God exists, of the divine nature. Another sort of puzzle concerns the consistency of attributing two or more properties to philosophy of religion philosophy of religion 696    696 God. Consider the claim that God is both immutable and omniscient. An immutable being is one that cannot undergo internal change, and an omniscient being knows all truths, and believes no falsehoods. If God is omniscient, it seems that God must first know and hence believe that it is now Tuesday and not believe that it is now Wednesday and later know and hence believe that it is now Wednesday and not believe that it is now Tuesday. If so, God’s beliefs change, and since change of belief is an internal change, God is not immutable. So it appears that God is not immutable if God is omniscient. A resolution of this puzzle would further contribute to enriching the philosophical understanding of the concept of God. It is, of course, one thing to elaborate a coherent concept of God; it is quite another to know, apart from revelation, that such a being actually exists. A proof of the existence of God would yield such knowledge, and it is the task of natural theology to evaluate arguments that purport to be such proofs. As opposed to revealed theology, natural theology restricts the assumptions fit to serve as premises in its arguments to things naturally knowable by humans, i.e., knowable without special revelation from supernatural sources. Many people have hoped that such natural religious knowledge could be universally communicated and would justify a form of religious practice that would appeal to all humankind because of its rationality. Such a religion would be a natural religion. The history of natural theology has produced a bewildering variety of arguments for the existence of God. The four main types are these: ontological arguments, cosmological arguments, teleological arguments, and moral arguments. The earliest and most famous version of the ontological argument was set forth by Anselm of Canterbury in chapter 2 of his Proslogion. It is a bold attempt to deduce the existence of God from the concept of God: we understand God to be a perfect being, something than which nothing greater can be conceived. Because we have this concept, God at least exists in our minds as an object of the understanding. Either God exists in the mind alone, or God exists both in the mind and as an extramental reality. But if God existed in the mind alone, then we could conceive of a being greater than that than which nothing greater can be conceived, namely, one that also existed in extramental reality. Since the concept of a being greater than that than which nothing greater can be conceived is incoherent, God cannot exist in the mind alone. Hence God exists not only in the mind but also in extramental reality. The most celebrated criticism of this form of the argument was Kant’s, who claimed that existence is not a real predicate. For Kant, a real predicate contributes to determining the content of a concept and so serves as a part of its definition. But to say that something falling under a concept exists does not add to the content of a concept; there is, Kant said, no difference in conceptual content between a hundred real dollars and a hundred imaginary dollars. Hence whether or not there exists something that corresponds to a concept cannot be settled by definition. The existence of God cannot be deduced from the concept of a perfect being because existence is not contained in the concept or the definition of a perfect being. Contemporary philosophical discussion has focused on a slightly different version of the ontological argument. In chapter 3 of Proslogion Anselm suggested that something than which nothing greater can be conceived cannot be conceived not to exist and so exists necessarily. Following this lead, such philosophers as Charles Hartshorne, Norman Malcolm, and Alvin Plantinga have contended that God cannot be a contingent being who exists in some possible worlds but not in others. The existence of a perfect being is either necessary, in which case God exists in every possible world, or impossible, in which case God exists in no possible worlds. On this view, if it is so much as possible that a perfect being exists, God exists in every possible world and hence in the actual world. The crucial premise in this form of the argument is the assumption that the existence of a perfect being is possible; it is not obviously true and could be rejected without irrationality. For this reason, Plantinga concedes that the argument does not prove or establish its conclusion, but maintains that it does make it rational to accept the existence of God. The key premises of various cosmological arguments are statements of obvious facts of a general sort about the world. Thus, the argument to a first cause begins with the observation that there are now things undergoing change and things causing change. If something is a cause of such change only if it is itself caused to change by something else, then there is an infinitely long chain of causes of change. But, it is alleged, there cannot be a causal chain of infinite length. Therefore there is something that causes change, but is not caused to change by anything else, i.e., a first cause. Many critics of this form of the argument deny its assumption that there cannot be an infinite causal regress or chain of causes. This argument also fails to show that there is only one first cause and does not prove that a first cause must have such divine attributes as omniscience, omnipotence, and perfect goodness. A version of the cosmological argument that has attracted more attention from contemporary philosophers is the argument from contingency to necessity. It starts with the observation that there are contingent beings  beings that could have failed to exist. Since contingent beings do not exist of logical necessity, a contingent being must be caused to exist by some other being, for otherwise there would be no explanation of why it exists rather than not doing so. Either the causal chain of contingent beings has a first member, a contingent being not caused by another contingent being, or it is infinitely long. If, on the one hand, the chain has a first member, then a necessary being exists and causes it. After all, being contingent, the first member must have a cause, but its cause cannot be another contingent being. Hence its cause has to be non-contingent, i.e., a being that could not fail to exist and so is necessary. If, on the other hand, the chain is infinitely long, then a necessary being exists and causes the chain as a whole. This is because the chain as a whole, being itself contingent, requires a cause that must be noncontingent since it is not part of the chain. In either case, if there are contingent beings, a necessary being exists. So, since contingent beings do exist, there is a necessary being that causes their existence. Critics of this argument attack its assumption that there must be an explanation for the existence of every contingent being. Rejecting the principle that there is a sufficient reason for the existence of each contingent thing, they argue that the existence of at least some contingent beings is an inexplicable brute fact. And even if the principle of sufficient reason is true, its truth is not obvious and so it would not be irrational to deny it. Accordingly, William Rowe b.1 concludes that this version of the cosmological argument does not prove the existence of God, but he leaves open the question of whether it shows that theistic belief is reasonable. The starting point of teleological arguments is the phenomenon of goal-directedness in nature. Aquinas, e.g., begins with the claim that we see that things which lack intelligence act for an end so as to achieve the best result. Modern science has discredited this universal metaphysical teleology, but many biological systems do seem to display remarkable adaptations of means to ends. Thus, as William Paley 17431805 insisted, the eye is adapted to seeing and its parts cooperate in complex ways to produce sight. This suggests an analogy between such biological systems and human artifacts, which are known to be products of intelligent design. Spelled out in mechanical terms, the analogy grounds the claim that the world as a whole is like a vast machine composed of many smaller machines. Machines are contrived by intelligent human designers. Since like effects have like causes, the world as a whole and many of its parts are therefore probably products of design by an intelligence resembling the human but greater in proportion to the magnitude of its effects. Because this form of the argument rests on an analogy, it is known as the analogical argument for the existence of God; it is also known as the design argument since it concludes the existence of an intelligent designer of the world. Hume subjected the design argument to sustained criticism in his Dialogues Concerning Natural Religion. If, as most scholars suppose, the character Philo speaks for Hume, Hume does not actually reject the argument. He does, however, think that it warrants only the very weak conclusion that the cause or causes of order in the universe probably bear some remote analogy to human intelligence. As this way of putting it indicates, the argument does not rule out polytheism; perhaps different minor deities designed lions and tigers. Moreover, the analogy with human artificers suggests that the designer or designers of the universe did not create it from nothing but merely imposed order on already existing matter. And on account of the mixture of good and evil in the universe, the argument does not show that the designer or designers are morally admirable enough to deserve obedience or worship. Since the time of Hume, the design argument has been further undermined by the emergence of Darwinian explanations of biological adaptations in terms of natural selection that give explanations of such adaptations in terms of intelligent design stiff competition. Some moral arguments for the existence of God conform to the pattern of inference to the best explanation. It has been argued that the hypothesis that morality depends upon the will of God provides the best explanation of the objectivity of moral obligations. Kant’s moral argument, which is probably the best-known specimen of this type, takes a different tack. According to Kant, the complete good consists of perfect virtue rewarded with perfect happiness, and virtue deserves to be rewarded with proportional happiness because it makes one worthy to be happy. If morality is to command the allegiance of reason, the complete good must be a real possibility, and so practical reason is entitled to postulate that the conditions necessary to guarantee its possibility obtain. As far as anyone can tell, nature and its laws do not furnish such a guarantee; in this world, apparently, the virtuous often suffer while the vicious flourish. And even if the operation of natural laws were to produce happiness in proportion to virtue, this would be merely coincidental, and hence finite moral agents would not have been made happy just because they had by their virtue made themselves worthy of happiness. So practical reason is justified in postulating a supernatural agent with sufficient goodness, knowledge, and power to ensure that finite agents receive the happiness they deserve as a reward for their virtue, though theoretical reason can know nothing of such a being. Critics of this argument have denied that we must postulate a systematic connection between virtue and happiness in order to have good reasons to be moral. Indeed, making such an assumption might actually tempt one to cultivate virtue for the sake of securing happiness rather than for its own sake. It seems therefore that none of these arguments by itself conclusively proves the existence of God. However, some of them might contribute to a cumulative case for the existence of God. According to Richard Swinburne, cosmological, teleological, and moral arguments individually increase the probability of God’s existence even though none of them makes it more probable than not. But when other evidence such as that deriving from providential occurrences and religious experiences is added to the balance, Swinburne concludes that theism becomes more probable than its negation. Whether or not he is right, it does appear to be entirely correct to judge the rationality of theistic belief in the light of our total evidence. But there is a case to be made against theism too. Philosophers of religion are interested in arguments against the existence of God, and fairness does seem to require admitting that our total evidence contains much that bears negatively on the rationality of belief in God. The problem of evil is generally regarded as the strongest objection to theism. Two kinds of evil can be distinguished. Moral evil inheres in the wicked actions of moral agents and the bad consequences they produce. An example is torturing the innocent. When evil actions are considered theologically as offenses against God, they are regarded as sins. Natural evils are bad consequences that apparently derive entirely from the operations of impersonal natural forces, e.g. the human and animal suffering produced by natural catastrophes such as earthquakes and epidemics. Both kinds of evil raise the question of what reasons an omniscient, omnipotent, and perfectly good being could have for permitting or allowing their existence. Theodicy is the enterprise of trying to answer this question and thereby to justify the ways of God to humans. It is, of course, possible to deny the presuppositions of the question. Some thinkers have held that evil is unreal; others have maintained that the deity is limited and so lacks the power or knowledge to prevent the evils that occur. If one accepts the presuppositions of the question, the most promising strategy for theodicy seems to be to claim that each evil God permits is necessary for some greater good or to avoid some alternative to it that is at least as bad if not worse. The strongest form of this doctrine is the claim made by Leibniz that this is the best of all possible worlds. It is unlikely that humans, with their cognitive limitations, could ever understand all the details of the greater goods for which evils are necessary, assuming that such goods exist; however, we can understand how some evils contribute to achieving goods. According to the soul-making theodicy of John Hick b.2, which is rooted in a tradition going back to Irenaeus, admirable human qualities such as compassion could not exist except as responses to suffering, and so evil plays a necessary part in the formation of moral character. But this line of thought does not seem to provide a complete theodicy because much animal suffering occurs unnoticed by humans and child abuse often destroys rather than strengthens the moral character of its victims. Recent philosophical discussion has often focused on the claim that the existence of an omniscient, omnipotent, and perfectly good being is logically inconsistent with the existence of evil or of a certain quantity of evil. This is the logical problem of evil, and the most successful response to it has been the free will defense. Unlike a theodicy, this defense does not speculate about God’s reasons for permitting evil but merely argues that God’s existence is consistent with the existence of evil. Its key idea is that moral good cannot exist apart from libertarian free actions that are not causally determined. If God aims to produce moral good, God must create free creatures upon whose cooperation he must depend, and so divine omnipotence is limited by the freedom God confers on creatures. Since such creatures are also free to do evil, it is possible that God could not have created a world containing moral good but no moral evil. Plantinga extends the defense from moral to natural evil by suggesting that it is also possible that all natural evil is due to the free actions of non-human persons such as Satan and his cohorts. Plantinga and Swinburne have also addressed the probabilistic problem of evil, which is the claim that the existence of evil disconfirms or renders improbable the hypothesis that God exists. Both of them argue for the conclusion that this is not the case. Finally, it is worth mentioning three other topics on which contemporary philosophers of religion have worked to good effect. Important studies of the meaning and use of religious language were stimulated by the challenge of logical positivism’s claim that theological language is cognitively meaningless. Defenses of such Christian doctrines as the Trinity, Incarnation, and Atonement against various philosophical objections have recently been offered by people committed to elaborating an explicitly Christian philosophy. And a growing appreciation of religious pluralism has both sharpened interest in questions about the cultural relativity of religious rationality and begun to encourage progress toward a comparative philosophy of religions. Such work helps to make philosophy of religion a lively and diverse field of inquiry. Grice: “It is extremely important that in a dictionary entry we keep the ‘philosophical’ – surely we are not lower ourselves to the level of a theologian – if I am a theologican, I am a philosophical theologian. --  theodicy from Grecian theos, ‘God’, and dike, ‘justice’, a defense of the justice or goodness of God in the face of doubts or objections arising from the phenomena of evil in the world ‘evil’ refers here to bad states of affairs of any sort. Many types of theodicy have been proposed and vigorously debated; only a few can be sketched here. 1 It has been argued that evils are logically necessary for greater goods e.g., hardships for the full exemplification of certain virtues, so that even an omnipotent being roughly, one whose power has no logically contingent limits would have a morally sufficient reason to cause or permit the evils in order to obtain the goods. Leibniz, in his Theodicy 1710, proposed a particularly comprehensive theodicy of this type. On his view, God had adequate reason to bring into existence the actual world, despite all its evils, because it is the best of all possible worlds, and all actual evils are essential ingredients in it, so that omitting any of them would spoil the design of the whole. Aside from issues about whether actual evils are in fact necessary for greater goods, this approach faces the question whether it assumes wrongly that the end justifies the means. 2 An important type of theodicy traces some or all evils to sinful free actions of humans or other beings such as angels created by God. Proponents of this approach assume that free action in creatures is of great value and is logically incompatible with divine causal control of the creatures’ actions. It follows that God’s not intervening to prevent sins is necessary, though the sins themselves are not, to the good of created freedom. This is proposed as a morally sufficient reason for God’s not preventing them. It is a major task for this type of theodicy to explain why God would permit those evils that are not themselves free choices of creatures but are at most consequences of such choices. 3 Another type of theodicy, both ancient and currently influential among theologians, though less congenial to orthodox traditions in the major theistic religions, proposes to defend God’s goodness by abandoning the doctrine that God is omnipotent. On this view, God is causally, rather than logically, unable to prevent many evils while pursuing sufficiently great goods. A principal sponsor of this approach at present is the movement known as process theology, inspired by Whitehead; it depends on a complex metaphysical theory about the nature of causal relationships. 4 Other theodicies focus more on outcomes than on origins. Some religious beliefs suggest that God will turn out to have been very good to created persons by virtue of gifts especially religious gifts, such as communion with God as supreme Good that may be bestowed in a life Tetractys theodicy 910   910 after death or in religious experience in the present life. This approach may be combined with one of the other types of theodicy, or adopted by people who think that God’s reasons for permitting evils are beyond our finding out.  Then there’s heologia naturalis Latin, ‘natural theology’, theology that uses the methods of investigation and standards of rationality of any other area of philosophy. Traditionally, the central problems of natural theology are proofs for the existence of God and the problem of evil. In contrast with natural theology, supernatural theology uses methods that are supposedly revealed by God and accepts as fact beliefs that are similarly outside the realm of rational acceptability. Relying on a prophet or a pope to settle factual questions would be acceptable to supernatural, but not to natural, theology. Nothing prevents a natural theologian from analyzing concepts that can be used sanguinely by supernatural theologians, e.g., revelation, miracles, infallibility, and the doctrine of the Trinity. Theologians often work in both areas, as did, e.g., Anselm and Aquinas. For his brilliant critiques of traditional theology, Hume deserves the title of “natural anti-theologian.”  Grice was totally against “the philosophy of X” – never the philosophy of god – but philosophical theology -- theological naturalism, the attempt to develop a naturalistic conception of God. As a philosophical position, naturalism holds 1 that the only reliable methods of knowing what there is are methods continuous with those of the developed sciences, and 2 that the application of those methods supports the view that the constituents of reality are either physical or are causally dependent on physical things and their modifications. Since supernaturalism affirms that God is purely spiritual and causally independent of physical things, naturalists hold that either belief in God must be abandoned as rationally unsupported or the concept of God must be reconstituted consistently with naturalism. Earlier attempts to do the latter include the work of Feuerbach and Comte. In twentieth-century  naturalism the most significant attempts to develop a naturalistic conception of God are due to Dewey and Henry Nelson Wieman 45. In A Common Faith Dewey proposed a view of God as the unity of ideal ends resulting from human imagination, ends arousing us to desire and action. Supernaturalism, he argued, was the product of a primitive need to convert the objects of desire, the greatest ideals, into an already existing reality. In contrast to Dewey, Wieman insisted on viewing God as a process in the natural world that leads to the best that humans can achieve if they but submit to its working in their lives. In his earlier work he viewed God as a cosmic process that not only works for human good but is what actually produced human life. Later he identified God with creative interchange, a process that occurs only within already existing human communities. While Wieman’s God is not a human creation, as are Dewey’s ideal ends, it is difficult to see how love and devotion are appropriate to a natural process that works as it does without thought or purpose. Thus, while Dewey’s God ideal ends lacks creative power but may well qualify as an object of love and devotion, Wieman’s God a process in nature is capable of creative power but, while worthy of our care and attention, does not seem to qualify as an object of love and devotion. Neither view, then, satisfies the two fundamental features associated with the traditional idea of God: possessing creative power and being an appropriate object of supreme love and devotion.  H. P. Grice, “Why I never pursued a doctorate in divinity!” --. philosophical theology: Grice: “My mother was High Church, but my father was a non-conformist, and the fact that my resident paternal aunt was a converted Roman certainly did not help!” -- Philosophical theology -- deism, the view that true religion is natural religion. Some self-styled Christian deists accepted revelation although they argued that its content is essentially the same as natural religion. Most deists dismissed revealed religion as a fiction. God wants his creatures to be happy and has ordained virtue as the means to it. Since God’s benevolence is disinterested, he will ensure that the knowledge needed for happiness is universally accessible. Salvation cannot, then, depend on special revelation. True religion is an expression of a universal human nature whose essence is reason and is the same in all times and places. Religious traditions such as Christianity and Islam originate in credulity, political tyranny, and priestcraft, which corrupt reason and overlay natural religion with impurities. Deism is largely a seventeenth- and eighteenth-century phenomenon and was most prominent in England. Among the more important English deists were John Toland 16701722, Anthony Collins 16761729, Herbert of Cherbury 15831648, Matthew Tindal 16571733, and Thomas Chubb 16791747. Continental deists included Voltaire and Reimarus. Thomas Paine and Elihu Palmer 17641806 were prominent  deists. Orthodox writers in this period use ‘deism’ as a vague term of abuse. By the late eighteenth century, the term came to mean belief in an “absentee God” who creates the world, ordains its laws, and then leaves it to its own devices. Philosophical theology -- de Maistre, Joseph-Marie, political theorist, diplomat, and Roman Catholic exponent of theocracy. He was educated by the Jesuits in Turin. His counterrevolutionary political philosophy aimed at restoring the foundations of morality, the family, society, and the state in postrevolutionary Europe. Against Enlightenment ideals, he reclaimed Thomism, defended the hereditary and absolute monarchy, and championed ultramontanism The Pope, 1821. Considerations on France 1796 argues that the decline of moral and religious values was responsible for the “satanic” 1789 revolution. Hence Christianity and Enlightenment philosophy were engaged in a fight to the death that he claimed the church would eventually win. Deeply pessimistic about human nature, the Essay on the Generating Principle of Political Constitutions 1810 traces the origin of authority in the human craving for order and discipline. Saint Petersburg Evenings 1821 urges philosophy to surrender to religion and reason to faith. Philosophical theology -- divine attributes, properties of God; especially, those properties that are essential and unique to God. Among properties traditionally taken to be attributes of God, omnipotence, omniscience, and omnibenevolence are naturally taken to mean having, respectively, power, knowledge, and moral goodness to the maximum degree. Here God is understood as an eternal or everlasting being of immense power, knowledge, and goodness, who is the creator and sustainer of the universe and is worthy of human worship. Omnipotence is maximal power. Some philosophers, notably Descartes, have thought that omnipotence requires the ability to do absolutely anything, including the logically impossible. Most classical theists, however, understood omnipotence as involving vast powers, while nevertheless being subject to a range of limitations of ability, including the inability to do what is logically impossible, the inability to change the past or to do things incompatible with what has happened, and the inability to do things that cannot be done by a being who has other divine attributes, e.g., to sin or to lie. Omniscience is unlimited knowledge. According to the most straightforward account, omniscience is knowledge of all true propositions. But there may be reasons for recognizing a limitation on the class of true propositions that a being must know in order to be omniscient. For example, if there are true propositions about the future, omniscience would then include foreknowledge. But some philosophers have thought that foreknowledge of human actions is incompatible with those actions being free. This has led some to deny that there are truths about the future and others to deny that such truths are knowable. In the latter case, omniscience might be taken to be knowledge of all knowable truths. Or if God is eternal and if there are certain tensed or temporally indexical propositions that can be known only by someone who is in time, then omniscience presumably does not extend to such propositions. It is a matter of controversy whether omniscience includes middle knowledge, i.e., knowledge of what an agent would do if other, counterfactual, conditions were to obtain. Since recent critics of middle knowledge in contrast to Báñez and other sixteenth-century Dominican opponents of Molina usually deny that the relevant counterfactual conditionals alleged to be the object of such knowledge are true, denying the possibility of middle knowledge need not restrict the class of true propositions a being must know in order to be omniscient. Finally, although the concept of omniscience might not itself constrain how an omniscient being acquires its knowledge, it is usually held that God’s knowledge is neither inferential i.e., derived from premises or evidence nor dependent upon causal processes. Omnibenevolenceis, literally, complete desire for good; less strictly, perfect moral goodness. Traditionally it has been thought that God does not merely happen to be good but that he must be so and that he is unable to do what is wrong. According to the former claim God is essentially good; according to the latter he is impeccable. It is a matter of controversy whether God is perfectly good in virtue of complying with an external moral standard or whether he himself sets the standard for goodness. Divine sovereignty is God’s rule over all of creation. According to this doctrine God did not merely create the world and then let it run on its own; he continues to govern it in complete detail according to his good plan. Sovereignty is thus related to divine providence. A difficult question is how to reconcile a robust view of God’s control of the world with libertarian free will. Aseity or perseity is complete independence. In a straightforward sense, God is not dependent on anyone or anything for his existence. According to stronger interpretation of aseity, God is completely independent of everything else, including his properties. This view supports a doctrine of divine simplicity according to which God is not distinct from his properties. Simplicity is the property of having no parts of any kind. According to the doctrine of divine simplicity, God not only has no spatial or temporal parts, but there is no distinction between God and his essence, between his various attributes in him omniscience and omnipotence, e.g., are identical, and between God and his attributes. Attributing simplicity to God was standard in medieval theology, but the doctrine has seemed to many contemporary philosophers to be baffling, if not incoherent.  divine command ethics, an ethical theory according to which part or all of morality divine attributes divine command ethics 240   240 depends upon the will of God as promulgated by divine commands. This theory has an important place in the history of Christian ethics. Divine command theories are prominent in the Franciscan ethics developed by John Duns Scotus and William Ockham; they are also endorsed by disciples of Ockham such as d’Ailly, Gerson, and Gabriel Biel; both Luther and Calvin adopt divine command ethics; and in modern British thought, important divine command theorists include Locke, Berkeley, and Paley. Divine command theories are typically offered as accounts of the deontological part of morality, which consists of moral requirements obligation, permissions rightness, and prohibitions wrongness. On a divine command conception, actions forbidden by God are morally wrong because they are thus forbidden, actions not forbidden by God are morally right because they are not thus forbidden, and actions commanded by God are morally obligatory because they are thus commanded. Many Christians find divine command ethics attractive because the ethics of love advocated in the Gospels makes love the subject of a command. Matthew 22:3740 records Jesus as saying that we are commanded to love God and the neighbor. According to Kierkegaard, there are two reasons to suppose that Christian love of neighbor must be an obligation imposed by divine command: first, only an obligatory love can be sufficiently extensive to embrace everyone, even one’s enemies; second, only an obligatory love can be invulnerable to changes in its objects, a love that alters not when it alteration finds. The chief objection to the theory is that dependence on divine commands would make morality unacceptably arbitrary. According to divine command ethics, murder would not be wrong if God did not exist or existed but failed to forbid it. Perhaps the strongest reply to this objection appeals to the doctrines of God’s necessary existence and essential goodness. God could not fail to exist and be good, and so God could not fail to forbid murder. In short, divine commands are not arbitrary fiats.  divine foreknowledge, God’s knowledge of the future. It appears to be a straightforward consequence of God’s omniscience that he has knowledge of the future, for presumably omniscience includes knowledge of all truths and there are truths about the future. Moreover, divine foreknowledge seems to be required by orthodox religious commitment to divine prophecy and divine providence. In the former case, God could not reliably reveal what will happen if he does know what will happen. And in the latter case, it is difficult to see how God could have a plan for what happens without knowing what that will be. A problem arises, however, in that it has seemed to many that divine foreknowledge is incompatible with human free action. Some philosophers notably Boethius have reasoned as follows: If God knows that a person will do a certain action, then the person must perform that action, but if a person must perform an action, the person does not perform the action freely. So if God knows that a person will perform an action, the person does not perform the action freely. This reason for thinking that divine foreknowledge is incompatible with human free action commits a simple modal fallacy. What must be the case is the conditional that if God knows that a person will perform an action then the person will in fact perform the action. But what is required to derive the conclusion is the implausible claim that from the assumption that God knows that a person will perform an action it follows not simply that the person will perform the action but that the person must perform it. Perhaps other attempts to demonstrate the incompatibility, however, are not as easily dismissed. One response to the apparent dilemma is to say that there really are no such truths about the future, either none at all or none about events, like future free actions, that are not causally necessitated by present conditions. Another response is to concede that there are truths about the future but to deny that truths about future free actions are knowable. In this case omniscience may be understood as knowledge, not of all truths, but of all knowable truths. A third, and historically important, response is to hold that God is eternal and that from his perspective everything is present and thus not future. These responses implicitly agree that divine foreknowledge is incompatible with human freedom, but they provide different accounts of omniscience according to which it does not include foreknowledge, or, at any rate, not foreknowledge of future free actions.  Philosophical theology -- double truth, the theory that a thing can be true in philosophy or according to reason while its opposite is true in theology or according to faith. It serves as a response to conflicts between reason and faith. For example, on one interpretation of Aristotle, there is only one rational human soul, whereas, according to Christian theology, there are many rational human souls. The theory of double truth was attributed to Averroes and to Latin Averroists such as Siger of Brabant and Boethius of Dacia by their opponents, but it is doubtful that they actually held it. Averroes seems to have held that a single truth is scientifically formulated in philosophy and allegorically expressed in theology. Latin Averroists apparently thought that philosophy concerns what would have been true by natural necessity absent special divine intervention, and theology deals with what is actually true by virtue of such intervention. On this view, there would have been only one rational human soul if God had not miraculously intervened to multiply what by nature could not be multiplied. No one clearly endorsed the view that rational human souls are both only one and also many in number.  H. P. Grice, “Must the Articles be 39 – and if we add one more, what might it say?.”

Scientism: One of the twelve labours of H. P. Grice --. Grice: “When Cicero coined ‘scientia’ out of scire he didn’t know what he was doing!” -- philosophy of science, the branch of philosophy that is centered on a critical examination of the sciences: their methods and their results. One branch of the philosophy of science, methodology, is closely related to the theory of knowledge. It explores the methods by which science arrives at its posited truths concerning the world and critically explores alleged rationales for these methods. Issues concerning the sense in which theories are accepted in science, the nature of the confirmation relation between evidence and hypothesis, the degree to which scientific claims can be falsified by observational data, and the like, are the concern of methodology. Other branches of the philosophy of science are concerned with the meaning and content of the posited scientific results and are closely related to metaphysics and the philosophy of language. Typical problems examined are the nature of scientific laws, the cognitive content of scientific theories referring to unobservables, and the structure of scientific explanations. Finally, philosophy of science explores specific foundational questions arising out of the specific results of the sciences. Typical questions explored might be metaphysical presuppositions of space-time theories, the role of probability in statistical physics, the interpretation of measurement in quantum theory, the structure of explanations in evolutionary biology, and the like. Concepts of the credibility of hypotheses. Some crucial concepts that arise when issues of the credibility of scientific hypotheses are in question are the following: Inductivism is the view that hypotheses can receive evidential support from their predictive success with respect to particular cases falling under them. If one takes the principle of inductive inference to be that the future will be like the past, one is subject to the skeptical objection that this rule is empty of content, and even self-contradictory, if any kind of “similarity” of cases is permitted. To restore content and consistency to the rule, and for other methodological purposes as well, it is frequently alleged that only natural kinds, a delimited set of “genuine” properties, should be allowed in the formulation of scientific hypotheses. The view that theories are first arrived at as creative hypotheses of the scientist’s imagination and only then confronted, for justificatory purposes, with the observational predictions deduced from them, is called the hypotheticodeductive model of science. This model is contrasted with the view that the very discovery of hypotheses is somehow “generated” out of accumulated observational data. The view that hypotheses are confirmed to the degree that they provide the “best explanatory account” of the data is often called abduction and sometimes called inference to the best explanation. The alleged relation that evidence bears to hypothesis, warranting its truth but not, generally, guaranteeing that truth, is called confirmation. Methodological accounts such as inductivism countenance such evidential warrant, frequently speaking of evidence as making a hypothesis probable but not establishing it with certainty. Probability in the confirmational context is supposed to be a relationship holding between propositions that is quantitative and is described by the formal theory of probability. It is supposed to measure the “degree of support” that one proposition gives to another, e.g. the degree of support evidential statements give to a hypothesis allegedly supported by them. Scientific methodologists often claim that science is characterized by convergence. This is the claim that scientific theories in their historical order are converging to an ultimate, final, and ideal theory. Sometimes this final theory is said to be true because it corresponds to the “real world,” as in realist accounts of convergence. In pragmatist versions this ultimate theory is the defining standard of truth. It is sometimes alleged that one ground for choosing the most plausible theory, over and above conformity of the theory with the observational data, is the simplicity of the theory. Many versions of this thesis exist, some emphasizing formal elements of the theory and others, e.g., emphasizing paucity of ontological commitment by the theory as the measure of simplicity. It is sometimes alleged that in choosing which theory to believe, the scientific community opts for theories compatible with the data that make minimal changes in scientific belief necessary from those demanded by previously held theory. The believer in methodological conservatism may also try to defend such epistemic conservatism as normatively rational. An experiment that can decisively show a scientific hypothesis to be false is called a crucial experiment for the hypothesis. It is a thesis of many philosophers that for hypotheses that function in theories and can only confront observational data when conjoined with other theoretical hypotheses, no absolutely decisive crucial experiment can exist. Concepts of the structure of hypotheses. Here are some of the essential concepts encountered when it is the structure of scientific hypotheses that is being explored: In its explanatory account of the world, science posits novel entities and properties. Frequently these are alleged to be not accessible to direct observation. A theory is a set of hypotheses positing such entities and properties. Some philosophers of science divide the logical consequences of a theory into those referring only to observable things and features and those referring to the unobservables as well. Various reductionist, eliminationist, and instrumentalist approaches to theory agree that the full cognitive content of a theory is exhausted by its observational consequences reported by its observation sentences, a claim denied by those who espouse realist accounts of theories. The view that the parts of a theory that do not directly relate observational consequences ought not to be taken as genuinely referential at all, but, rather, as a “mere linguistic instrument” allowing one to derive observational results from observationally specifiable posits, is called instrumentalism. From this point of view terms putatively referring to unobservables fail to have genuine reference and individual non-observational sentences containing such terms are not individually genuinely true or false. Verificationism is the general name for the doctrine that, in one way or another, the semantic content of an assertion is exhausted by the conditions that count as warranting the acceptance or rejection of the assertion. There are many versions of verificationist doctrines that try to do justice both to the empiricist claim that the content of an assertion is its totality of empirical consequences and also to a wide variety of anti-reductionist intuitions about meaning. The doctrine that theoretical sentences must be strictly translatable into sentences expressed solely in observational terms in order that the theoretical assertions have genuine cognitive content is sometimes called operationalism. The “operation” by which a magnitude is determined to have a specified value, characterized observationally, is taken to give the very meaning of attributing that magnitude to an object. The doctrine that the meanings of terms in theories are fixed by the role the terms play in the theory as a whole is often called semantic holism. According to the semantic holist, definitions of theoretical terms by appeal to observational terms cannot be given, but all of the theoretical terms have their meaning given “as a group” by the structure of the theory as a whole. A related doctrine in confirmation theory is that confirmation accrues to whole theories, and not to their individual assertions one at a time. This is confirmational holism. To see another conception of cognitive content, conjoin all the sentences of a theory together. Then replace each theoretical term in the sentence so obtained with a predicate variable and existentially quantify over all the predicate variables so introduced. This is the Ramsey sentence for a finitely axiomatized theory. This sentence has the same logical consequences framable in the observational vocabulary alone as did the original theory. It is often claimed that the Ramsey sentence for a theory exhausts the cognitive content of the theory. The Ramsey sentence is supposed to “define” the meaning of the theoretical terms of the original theory as well as have empirical consequences; yet by asserting the existence of the theoretical properties, it is sometimes alleged to remain a realist construal of the theory. The latter claim is made doubtful, however, by the existence of “merely representational” interpretations of the Ramsey sentence. Theories are often said to be so related that one theory is reducible to another. The study of the relation theories bear to one another in this context is said to be the study of intertheoretic reduction. Such reductive claims can have philosophical origins, as in the alleged reduction of material objects to sense-data or of spatiotemporal relations to causal relations, or they can be scientific discoveries, as in the reduction of the theory of light waves to the theory of electromagnetic radiation. Numerous “models” of the reductive relation exist, appropriate for distinct kinds and cases of reduction. The term scientific realism has many and varied uses. Among other things that have been asserted by those who describe themselves as scientific realists are the claims that “mature” scientific theories typically refer to real features of the world, that the history of past falsifications of accepted scientific theories does not provide good reason for persistent skepticism as to the truth claims of contemporary theories, and that the terms of theories that putatively refer to unobservables ought to be taken at their referential face value and not reinterpreted in some instrumentalistic manner. Internal realism denies irrealist claims founded on the past falsification of accepted theories. Internal realists are, however, skeptical of “metaphysical” claims of “correspondence of true theories to the real world” or of any notion of truth that can be construed in radically non-epistemic terms. While theories may converge to some ultimate “true” theory, the notion of truth here must be understood in some version of a Peircian idea of truth as “ultimate warranted assertability.” The claim that any theory that makes reference to posited unobservable features of the world in its explanatory apparatus will always encounter rival theories incompatible with the original theory but equally compatible with all possible observational data that might be taken as confirmatory of the original theory is the claim of the underdetermination thesis. A generalization taken to have “lawlike force” is called a law of nature. Some suggested criteria for generalizations having lawlike force are the ability of the generalization to back up the truth of claims expressed as counterfactual conditions; the ability of the generalization to be confirmed inductively on the basis of evidence that is only a proper subset of all the particular instances falling under the generality; and the generalization having an appropriate place in the simple, systematic hierarchy of generalizations important for fundamental scientific theories of the world. The application of a scientific law to a given actual situation is usually hedged with the proviso that for the law’s predictions to hold, “all other, unspecified, features of the situation are normal.” Such a qualifying clause is called a ceteris paribus clause. Such “everything else being normal” claims cannot usually be “filled out,” revealing important problems concerning the “open texture” of scientific claims. The claim that the full specification of the state of the world at one time is sufficient, along with the laws of nature, to fix the full state of the world at any other time, is the claim of determinism. This is not to be confused with claims of total predictability, since even if determinism were true the full state of the world at a time might be, in principle, unavailable for knowledge. Concepts of the foundations of physical theories. Here, finally, are a few concepts that are crucial in discussing the foundations of physical theories, in particular theories of space and time and quantum theory: The doctrine that space and time must be thought of as a family of spatial and temporal relations holding among the material constituents of the universe is called relationism. Relationists deny that “space itself” should be considered an additional constituent of the world over and above the world’s material contents. The doctrine that “space itself” must be posited as an additional constituent of the world over and above ordinary material things of the world is substantivalism. Mach’s principle is the demand that all physical phenomena, including the existence of inertial forces used by Newton to argue for a substantivalist position, be explainable in purely relationist terms. Mach speculated that Newton’s explanation for the forces in terms of acceleration with respect to “space itself” could be replaced with an explanation resorting to the acceleration of the test object with respect to the remaining matter of the universe the “fixed stars”. In quantum theory the claim that certain “conjugate” quantities, such as position and momentum, cannot be simultaneously “determined” to arbitrary degrees of accuracy is the uncertainty principle. The issue of whether such a lack of simultaneous exact “determination” is merely a limitation on our knowledge of the system or is, instead, a limitation on the system’s having simultaneous exact values of the conjugate quantities, is a fundamental one in the interpretation of quantum mechanics. Bell’s theorem is a mathematical result aimed at showing that the explanation of the statistical correlations that hold between causally noninteractive systems cannot always rely on the positing that when the systems did causally interact in the past independent values were fixed for some feature of each of the two systems that determined their future observational behavior. The existence of such “local hidden variables” would contradict the correlational predictions of quantum mechanics. The result shows that quantum mechanics has a profoundly “non-local” nature. Can quantum probabilities and correlations be obtained as averages over variables at some deeper level than those specifying the quantum state of a system? If such quantities exist they are called hidden variables. Many different types of hidden variables have been proposed: deterministic, stochastic, local, non-local, etc. A number of proofs exist to the effect that positing certain types of hidden variables would force probabilistic results at the quantum level that contradict the predictions of quantum theory. Complementarity was the term used by Niels Bohr to describe what he took to be a fundamental structure of the world revealed by quantum theory. Sometimes it is used to indicate the fact that magnitudes occur in conjugate pairs subject to the uncertainty relations. Sometimes it is used more broadly to describe such aspects as the ability to encompass some phenomena in a wave picture of the world and other phenomena in a particle picture, but implying that no one picture will do justice to all the experimental results. The orthodox formalization of quantum theory posits two distinct ways in which the quantum state can evolve. When the system is “unobserved,” the state evolves according to the deterministic Schrödinger equation. When “measured,” however, the system suffers a discontinuous “collapse of the wave packet” into a new quantum state determined by the outcome of the measurement process. Understanding how to reconcile the measurement process with the laws of dynamic evolution of the system is the measurement problem. Conservation and symmetry. A number of important physical principles stipulate that some physical quantity is conserved, i.e. that the quantity of it remains invariant over time. Early conservation principles were those of matter mass, of energy, and of momentum. These became assimilated together in the relativistic principle of the conservation of momentum-energy. Other conservation laws such as the conservation of baryon number arose in the theory of elementary particles. A symmetry in physical theory expressed the invariance of some structural feature of the world under some transformation. Examples are translation and rotation invariance in space and the invariance under transformation from one uniformly moving reference frame to another. Such symmetries express the fact that systems related by symmetry transformations behave alike in their physical evolution. Some symmetries are connected with space-time, such as those noted above, whereas others such as the symmetry of electromagnetism under socalled gauge transformations are not. A very important result of the mathematician Emma Noether shows that each conservation law is derivable from the existence of an associated underlying symmetry. Chaos theory and chaotic systems. In the history of the scientific study of deterministic systems, the paradigm of explanation has been the prediction of the future states of a system from a specification of its initial state. In order for such a prediction to be useful, however, nearby initial states must lead to future states that are close to one another. This is now known to hold only in exceptional cases. In general deterministic systems are chaotic systems, i.e., even initial states very close to one another will lead in short intervals of time to future states that diverge quickly from one another. Chaos theory has been developed to provide a wide range of concepts useful for describing the structure of the dynamics of such chaotic systems. The theory studies the features of a system that will determine if its evolution is chaotic or non-chaotic and provides the necessary descriptive categories for characterizing types of chaotic motion. Randomness. The intuitive distinction between a sequence that is random and one that is orderly plays a role in the foundations of probability theory and in the scientific study of dynamical systems. But what is a random sequence? Subjectivist definitions of randomness focus on the inability of an agent to determine, on the basis of his knowledge, the future occurrences in the sequence. Objectivist definitions of randomness seek to characterize it without reference to the knowledge of any agent. Some approaches to defining objective randomness are those that require probability to be the same in the original sequence and in subsequences “mechanically” selectable from it, and those that define a sequence as random if it passes every “effectively constructible” statistical test for randomness. Another important attempt to characterize objective randomness compares the length of a sequence to the length of a computer program used to generate the sequence. The basic idea is that a sequence is random if the computer programs needed to generate the sequence are as long as the sequence itself.  H. P. Grice, “My labour with Scientism.”

scire – scitum -- scientism: Grice: “Winch is not only happy with natural science that he wants a social science – linguistics included!” -- philosophy of the social sciences, the study of the logic and methods of the social sciences. Central questions include: What are the criteria of a good social explanation? How if at all are the social sciences distinct from the natural sciences? Is there a distinctive method for social research? Through what empirical procedures are social science assertions to be evaluated? Are there irreducible social laws? Are there causal relations among social phenomena? Do social facts and regularities require some form of reduction to facts about individuals? What is the role of theory in social explanation? The philosophy of social science aims to provide an interpretation of the social sciences that answers these questions. The philosophy of social science, like that of natural science, has both a descriptive and a prescriptive side. On the one hand, the field is about the social sciences  the explanations, methods, empirical arguments, theories, hypotheses, etc., that actually occur in the social science literature. This means that the philosopher needs extensive knowledge of several areas of social science research in order to be able to formulate an analysis of the social sciences that corresponds appropriately to scientists’ practice. On the other hand, the field is epistemic: it is concerned with the idea that scientific theories and hypotheses are put forward as true or probable, and are justified on rational grounds empirical and theoretical. The philosopher aims to provide a critical evaluation of existing social science methods and practices insofar as these methods are found to be less truth-enhancing than they might be. These two aspects of the philosophical enterprise suggest that philosophy of social science should be construed as a rational reconstruction of existing social science practice  a reconstruction guided by existing practice but extending beyond that practice by identifying faulty assumptions, forms of reasoning, and explanatory frameworks. Philosophers have disagreed over the relation between the social and natural sciences. One position is naturalism, according to which the methods of the social sciences should correspond closely to those of the natural sciences. This position is closely related to physicalism, the doctrine that all higher-level phenomena and regularities  including social phenomena  are ultimately reducible to physical entities and the laws that govern them. On the other side is the view that the social sciences are inherently distinct from the natural sciences. This perspective holds that social phenomena are metaphysically distinguishable from natural phenomena because they are intentional  they depend on the meaningful actions of individuals. On this view, natural phenomena admit of causal explanation, whereas social phenomena require intentional explanation. The anti-naturalist position also maintains that there is a corresponding difference between the methods appropriate to natural and social science. Advocates of the Verstehen method hold that there is a method of intuitive interpretation of human action that is radically distinct from methods of inquiry in the natural sciences. One important school within the philosophy of social science takes its origin in this fact of the meaningfulness of human action. Interpretive sociology maintains that the goal of social inquiry is to provide interpretations of human conduct within the context of culturally specific meaningful arrangements. This approach draws an analogy between literary texts and social phenomena: both are complex systems of meaningful elements, and the goal of the interpreter is to provide an interpretation of the elements that makes sense of them. In this respect social science involves a hermeneutic inquiry: it requires that the interpreter should tease out the meanings underlying a particular complex of social behavior, much as a literary critic pieces together an interpretation of the meaning of a complex philosophy of the social sciences philosophy of the social sciences 704    704 literary text. An example of this approach is Weber’s treatment of the relation between capitalism and the Protestant ethic. Weber attempts to identify the elements of western European culture that shaped human action in this environment in such a way as to produce capitalism. On this account, both Calvinism and capitalism are historically specific complexes of values and meanings, and we can better understand the emergence of capitalism by seeing how it corresponds to the meaningful structures of Calvinism. Interpretive sociologists often take the meaningfulness of social phenomena to imply that social phenomena do not admit of causal explanation. However, it is possible to accept the idea that social phenomena derive from the purposive actions of individuals without relinquishing the goal of providing causal explanations of social phenomena. For it is necessary to distinguish between the general idea of a causal relation between two events or conditions and the more specific idea of “causal determination through strict laws of nature.” It is true that social phenomena rarely derive from strict laws of nature; wars do not result from antecedent political tensions in the way that earthquakes result from antecedent conditions in plate tectonics. However, since non-deterministic causal relations can derive from the choices of individual persons, it is evident that social phenomena admit of causal explanation, and in fact much social explanation depends on asserting causal relations between social events and processes  e.g., the claim that the administrative competence of the state is a crucial causal factor in determining the success or failure of a revolutionary movement. A central goal of causal explanation is to discover the conditions existing prior to the event that, given the law-governed regularities among phenomena of this sort, were sufficient to produce this event. To say that C is a cause of E is to assert that the occurrence of C, in the context of a field of social processes and mechanisms F, brought about E or increased the likelihood of the occurrence of E. Central to causal arguments in the social sciences is the idea of a causal mechanism  a series of events or actions leading from cause to effect. Suppose it is held that the extension of a trolley line from the central city to the periphery caused the deterioration of public schools in the central city. In order to make out such a claim it is necessary to provide some account of the social and political mechanisms that join the antecedent condition to the consequent. An important variety of causal explanation in social science is materialist explanation. This type of explanation attempts to explain a social feature in terms of features of the material environment in the context of which the social phenomenon occurs. Features of the environment that often appear in materialist explanations include topography and climate; thus it is sometimes maintained that banditry thrives in remote regions because the rugged terrain makes it more difficult for the state to repress bandits. But materialist explanations may also refer to the material needs of society  e.g., the need to produce food and other consumption goods to support the population. Thus Marx holds that it is the development of the “productive forces” technology that drives the development of property relations and political systems. In each case the materialist explanation must refer to the fact of human agency  the fact that human beings are capable of making deliberative choices on the basis of their wants and beliefs  in order to carry out the explanation; in the banditry example, the explanation depends on the fact that bandits are prudent enough to realize that their prospects for survival are better in the periphery than in the core. So materialist explanations too accept the point that social phenomena depend on the purposive actions of individuals. A central issue in the philosophy of social science involves the relation between social regularities and facts about individuals. Methodological individualism is the position that asserts the primacy of facts about individuals over facts about social entities. This doctrine takes three forms: a claim about social entities, a claim about social concepts, and a claim about social regularities. The first version maintains that social entities are reducible to ensembles of individuals  as an insurance company might be reduced to the ensemble of employees, supervisors, managers, and owners whose actions constitute the company. Likewise, it is sometimes held that social concepts must be reducible to concepts involving only individuals  e.g., the concept of a social class might be defined in terms of concepts pertaining only to individuals and their behavior. Finally, it is sometimes held that social regularities must be derivable from regularities of individual behavior. There are several positions opposed to methodological individualism. At the extreme there is methodological holism  the doctrine that social entities, facts, and laws are autonomous and irreducible; for example, that social structures such as the state have dynamic properties independent of the beliefs and purposes of the particular persons who occupy positions within the structure. A third position intermediate between these two holds that every social explanation requires microfoundations  an account of the circumstances at the individual level that led individuals to behave in such ways as to bring about the observed social regularities. If we observe that an industrial strike is successful over an extended period of time, it is not sufficient to explain this circumstance by referring to the common interest that members of the union have in winning their demands. Rather, we need information about the circumstances of the individual union member that induce him or her to contribute to this public good. The microfoundations dictum does not require, however, that social explanations be couched in non-social concepts; instead, the circumstances of individual agents may be characterized in social terms. Central to most theories of explanation is the idea that explanation depends on general laws governing the phenomena in question. Thus the discovery of the laws of electrodynamics permitted the explanation of a variety of electromagnetic phenomena. But social phenomena derive from the actions of purposive men and women; so what kinds of regularities are available on the basis of which to provide social explanations? A fruitful research framework in the social sciences is the idea that men and women are rational, so it is possible to explain their behavior as the outcome of a deliberation about means of achieving their individual ends. This fact in turn gives rise to a set of regularities about individual behavior that may be used as a ground for social explanation. We may explain some complex social phenomenon as the aggregate result of the actions of a large number of individual agents with a hypothesized set of goals within a structured environment of choice. Social scientists have often been inclined to offer functional explanations of social phenomena. A functional explanation of a social feature is one that explains the presence and persistence of the feature in terms of the beneficial consequences the feature has for the ongoing working of the social system as a whole. It might be held, e.g., that sports clubs in working-class Britain exist because they give working-class people a way of expending energy that would otherwise go into struggles against an exploitative system, thus undermining social stability. Sports clubs are explained, then, in terms of their contribution to social stability. This type of explanation is based on an analogy between biology and sociology. Biologists explain species traits in terms of their contribution to reproductive fitness, and sociologists sometimes explain social traits in terms of their contribution to “social” fitness. However, the analogy is misleading, because there is a general mechanism establishing functionality in the biological realm that is not present in the social realm. This is the mechanism of natural selection, through which a species arrives at a set of traits that are locally optimal. There is no analogous process at work in the social realm, however; so it is groundless to suppose that social traits exist because of their beneficial consequences for the good of society as a whole or important subsystems within society. So functional explanations of social phenomena must be buttressed by specific accounts of the causal processes that underlie the postulated functional relationships.

physicalism: One of the twelve labours of H. P. Grice. (“As different from Naturalism, you know.”) - Churchland, p. s., philosopher and advocate of neurophilosophy. She received her B.Phil. from Oxford in 9 and held positions at the Unichün-tzu Churchland, Patricia Smith 140   140 versity of Manitoba and the Institute for Advanced Studies at Princeton, settling at the ofCalifornia,SanDiego, with appointments in philosophy and the Institute for Neural Computation. Skeptical of philosophy’s a priori specification of mental categories and dissatisfied with computational psychology’s purely top-down approach to their function, Churchland began studying the brain at the  of Manitoba medical school. The result was a unique merger of science and philosophy, a “neurophilosophy” that challenged the prevailing methodology of mind. Thus, in a series of articles that includes “Fodor on Language Learning” 8 and “A Perspective on Mind-Brain Research” 0, she outlines a new neurobiologically based paradigm. It subsumes simple non-linguistic structures and organisms, since the brain is an evolved organ; but it preserves functionalism, since a cognitive system’s mental states are explained via high-level neurofunctional theories. It is a strategy of cooperation between psychology and neuroscience, a “co-evolutionary” process eloquently described in Neurophilosophy 6 with the prediction that genuine cognitive phenomena will be reduced, some as conceptualized within the commonsense framework, others as transformed through the sciences. The same intellectual confluence is displayed through Churchland’s various collaborations: with psychologist and computational neurobiologist Terrence Sejnowski in The Computational Brain 2; with neuroscientist Rodolfo Llinas in The Mind-Brain Continuum 6; and with philosopher and husband Paul Churchland in On the Contrary 8 she and Paul Churchland are jointly appraised in R. McCauley, The Churchlands and Their Critics, 6. From the viewpoint of neurophilosophy, interdisciplinary cooperation is essential for advancing knowledge, for the truth lies in the intertheoretic details. Churchland: Paul M. b.2, -born  philosopher, leading proponent of eliminative materialism. He received his Ph.D. from the  of Pittsburgh in 9 and held positions at the Universities of Toronto, Manitoba, and the Institute for Advanced Studies at Princeton. He is professor of philosophy and member of the Institute for Neural Computation at the  of California, San Diego. Churchland’s literary corpus constitutes a lucidly written, scientifically informed narrative where his neurocomputational philosophy unfolds. Scientific Realism and the Plasticity of Mind 9 maintains that, though science is best construed realistically, perception is conceptually driven, with no observational given, while language is holistic, with meaning fixed by networks of associated usage. Moreover, regarding the structure of science, higher-level theories should be reduced by, incorporated into, or eliminated in favor of more basic theories from natural science, and, in the specific case, commonsense psychology is a largely false empirical theory, to be replaced by a non-sentential, neuroscientific framework. This skepticism regarding “sentential” approaches is a common thread, present in earlier papers, and taken up again in “Eliminative Material
ism and the Propositional Attitudes” 1. When fully developed, the non-sentential, neuroscientific framework takes the form of connectionist network or parallel distributed processing models. Thus, with essays in A Neurocomputational Perspective 9, Churchland adds that genuine psychological processes are sequences of activation patterns over neuronal networks. Scientific theories, likewise, are learned vectors in the space of possible activation patterns, with scientific explanation being prototypical activation of a preferred vector. Classical epistemology, too, should be neurocomputationally naturalized. Indeed, Churchland suggests a semantic view whereby synonymy, or the sharing of concepts, is a similarity between patterns in neuronal state-space. Even moral knowledge is analyzed as stored prototypes of social reality that are elicited when an individual navigates through other neurocomputational systems. The entire picture is expressed in The Engine of Reason, the Seat of the Soul 6 and, with his wife Patricia Churchland, by the essays in On the Contrary 8. What has emerged is a neurocomputational embodiment of the naturalist program, a panphilosophy that promises to capture science, epistemology, language, and morals in one broad sweep of its connectionist net. Refs.: H. P. Grice, “Physicalism and naturalism.” physicalism: On second thoughts, Grice saw that naturalism and physicalism were synonymous, but kept both! One of the twelve labours of Grice. in the widest sense of the term, materialism applied to the question of the nature of mind. So construed, physicalism is the thesis  call it ontological physicalism  that whatever exists or occurs is ultimately constituted out of physical entities. But sometimes ‘physicalism’ is used to refer to the thesis that whatever exists or occurs can be completely described in the vocabulary of physics. Such a view goes with either reductionism or eliminativism about the mental. Here reductionism is the view that psychological explanations, including explanations in terms of “folk-psychological” concepts such as those of belief and desire, are reducible to explanations formulable in a physical vocabulary, which in turn would imply that entities referred to in psychological explanations can be fully described in physical terms; and elminativism is the view that nothing corresponds to the terms in psychological explanations, and that the only correct explanations are in physical terms. The term ‘physicalism’ appears to have originated in the Vienna Circle, and the reductionist version initially favored there was a version of behaviorism: psychological statements were held to be translatable into behavioral statements, mainly hypothetical conditionals, expressible in a physical vocabulary. The psychophysical identity theory held by Herbert Feigl, Smart, and others, sometimes called type physicalism, is reductionist in a somewhat different sense. This holds that mental states and events are identical with neurophysiological states and events. While it denies that there can be analytic, meaning-preserving translations of mental statements into physicalistic ones, it holds that by means of synthetic “bridge laws,” identifying mental types with physical ones, mental statements can in principle be tr. into physicalistic ones with which they are at least nomologically equivalent if the terms in the bridge laws are rigid designators, the equivalence will be necessary. The possibility of such a translation is typically denied by functionalist accounts of mind, on the grounds that the same mental state may have indefinitely many different physical realizations, and sometimes on the grounds that it is logically possible, even if it never happens, that mental states should be realized non-physically. In his classic paper “The ‘mental’ and the ‘physical’ “ 8, Feigl distinguishes two senses of ‘physical’: ‘physical1’ and ‘physical2’. ‘Physical1’ is practically synonymous with ‘scientific’, applying to whatever is “an essential part of the coherent and adequate descriptive and explanatory account of the spatiotemporal world.” ‘Physical2’ refers to “the type of concepts and laws which suffice in principle for the explanation and prediction of inorganic processes.” It would seem that if Cartesian dualism were true, supposing that possible, then once an integrated science of the interaction of immaterial souls and material bodies had been developed, concepts for describing the former would count as physical1. Construed as an ontological doctrine, physicalism says that whatever exists or occurs is entirely constituted out of those entities that constitute inorganic things and processes. Construed as a reductionist or elminativist thesis about description and explanation, it is the claim that a vocabulary adequate for describing and explaining inorganic things and processes is adequate for describing and explaining whatever exists. While the second of these theses seems to imply the first, the first does not imply the second. It can be questioned whether the notion of a “full” description of what exists makes sense. And many ontological physicalists materialists hold that a reduction to explanations couched in the terminology of physics is impossible, not only in the case of psychological explanations but also in the case of explanations couched in the terminology of such special sciences as biology. Their objection to such reduction is not merely that a purely physical description of e.g. biological or psychological phenomena would be unwieldy; it is that such descriptions necessarily miss important laws and generalizations, ones that can only be formulated in terms of biological, psychological, etc., concepts. If ontological physicalists materialists are not committed to the reducibility of psychology to physics, neither are they committed to any sort of identity theory claiming that entities picked out by mental or psychological descriptions are identical to entities fully characterizable by physical descriptions. As already noted, materialists who are functionalists deny that there are typetype identities between mental entities and physical ones. And some deny that materialists are even committed to token-token identities, claiming that any psychological event could have had a different physical composition and so is not identical to any event individuated in terms of a purely physical taxonomy.  Refs.: H.

natura: the Grecian equivalent is “physis,” – whereas the Roman idea has to do with ‘birth,’ cf. ‘renaissance,’ the Grecian idea has to do with ‘growth,’  Grecian term for nature, primarily used to refer to the nature or essence of a living thing Aristotle, Metaphysics V.4. Physis is defined by Aristotle in Physics II.1 as a source of movement and rest that belongs to something in virtue of itself, and identified by him primarily with the form, rather than the matter, of the thing. The term is also used to refer to the natural world as a whole. Physis is often contrasted with techne, art; in ethics it is also contrasted with nomos, convention, e.g. by Callicles in Plato’s Gorgias 482e ff., who distinguishes natural from conventional justice. 

physiologicum: Oddly, among the twelve isms that attack Grice on his ascent to the city of eternal truth, there is Naturalism and Physicalism – but Roman natura is Grecian physis. In “Some remarks about the senses,” Grice distinguishes a physicalist identification of the senses (in terms of the different stimuli and the mechanisms that connects the organs to the brain) versus other criteria, notably one involving introspection and the nature of ‘experience’ – “providing,” he adds, that ‘seeing’ is an experience! Grice would use ‘natural,’ relying on the idea that it’s Grecian ‘physis.’ Liddell and Scott have “φύσις,” from “φύω,” and which they render as “origin.” the natural form or constitution of a person or thing as the result of growth, and hence nature, constitution, and nature as an originating power, “φ. λέγεται . . ὅθεν ἡ κίνησις ἡ πρώτη ἐν ἑκάστῳ τῶν φύσει ὄντων” Arist.Metaph.1014b16; concrete, the creation, 'Nature.’ Grice is casual in his use of ‘natural’ versus ‘non-natural’ in 1948 for the Oxford Philosophical Society. In later works, there’s a reference to naturalism, which is more serious. Refs.: The keyword should be ‘naturalism,’ but also Grice’s diatribes against ‘physicalism,’ and of course the ‘natural’ and ‘non-natural,’ BANC.

lapis philosophorum: alchemy: a quasi-scientific practice and mystical art, mainly ancient and medieval, that had two broad aims: to change baser metals into gold and to develop the elixir of life, the means to immortality. Classical Western alchemy probably originated in Egypt in the first three centuries A.D. with earlier Chin. and later Islamic and  variants and was practiced in earnest in Europe by such figures as Paracelsus and Newton until the eighteenth century. Western alchemy addressed concerns of practical metallurgy, but its philosophical significance derived from an early Grecian theory of the relations among the basic elements and from a religious-allegorical understanding of the alchemical transmutation of ores into gold, an understanding that treats this process as a spiritual ascent from human toward divine perfection. The purification of crude ores worldly matter into gold material perfection was thought to require a transmuting agent, the philosopher’s stone, a mystical substance that, when mixed with alcohol and swallowed, was believed to produce immortality spiritual perfection. The alchemical search for the philosopher’s stone, though abortive, resulted in the development of ultimately useful experimental tools e.g., the steam pump and methods e.g., distillation.

piaget: philosopher who profoundly influenced questions, theories, and methods in the study of cognitive development. The philosophical interpretation and implications of his work, however, remain controversial. Piaget regarded himself as engaged in genetic epistemology, the study of what knowledge is through an empirical investigation of how our epistemic relations to objects are improved. Piaget hypothesized that our epistemic relations are constructed through the progressive organization of increasingly complex behavioral interactions with physical objects. The cognitive system of the adult is neither learned, in the Skinnerian sense, nor genetically preprogrammed. Rather, it results from the organization of specific interactions whose character is shaped both by the features of the objects interacted with a process called accommodation and by the current cognitive system of the child a process called assimilation. The tendency toward equilibrium results in a change in the nature of the interaction as well as in the cognitive system. Of particular importance for the field of cognitive development were Piaget’s detailed descriptions and categorizations of changes in the organization of the cognitive system from birth through adolescence. That work focused on changes in the child’s understanding of such things as space, time, cause, number, length, weight, and morality. Among his major works are The Child’s Conception of Number 1, Biology and Knowledge 7, Genetic Epistemology 0, and Psychology and Epistemology 0.

pico della mirandola -- philosopher who wrote a series of 900 theses which he hoped to dispute publicly in Rome. Thirteen of these theses are criticized by a papal commission. When Pico defends himself in his “Apologia,” the pope condemns all 900 theses. Pico flees to France, but is imprisoned. On his escape, he returns to Florence and devotes himself to private study at the swimming-pool at his villa. He hoped to write a Concord of Plato and Aristotle, but the only part he was able to complete was “On Being and the One,” – “Blame it on the Toscana!” -- in which he uses Aquinas and Christianity to reconcile Plato’s and Aristotle’s views about God’s being and unity. Mirandola is often described as a syncretist, but in fact he made it clear that the truth of Christianity has priority over the prisca theologia or ancient wisdom found in the hermetic corpus and the cabala. Though he was interested in magic and astrology, Mirandola adopts a guarded attitude toward them in his “Heptaplus,” which contains a mystical interpretation of Genesis; and in his Disputations Against Astrology, he rejects them both. The treatise is largely technical, and the question of human freedom is set aside as not directly relevant. This fact casts some doubt on the popular thesis that Pico’s philosophy is a celebration of man’s freedom and dignity. Great weight has been placed on Pico’s “On the Dignity of Man.” This is a short oration intended as an introduction to the disputation of his 900 theses – all condemned by the evil pope --, and the title was suggested by his wife (“She actually suggested, “On the dignity of woman,” but I found that otiose.””). Mirandola has been interpreted as saying that man (or woman) is set apart from the rest of creation, and is completely free to form his (or her) own nature. In fact, as The Heptaplus shows, Pico sees man as a microcosm containing elements of the angelic, celestial, and elemental worlds. Man (if not woman) is thus firmly within the hierarchy of nature, and is a bond and link between the worlds. In the oration, the emphasis on freedom is a moral one: man is free to choose between good and evil. Grice: “This irritated Nietzsche so much that he wrote ‘beyond good and evil.’ Refs.: H. P.

Pur essendo Mirandola uno stato molto piccolo, i Pico governarono come sovrani indipendenti piuttosto che come nobili vassalli. I Pico della Mirandola erano strettamente imparentati agli Sforza, ai Gonzaga e agli Este, e i fratelli di Giovanni sposarono gli eredi al trono di Corsica, Ferrara, Bologna e Forlì.[2] Durante la sua vita Giovanni soggiornò in molte dimore. Tra queste, quando visse a Ferrara, quella che si trovava in via del Turco gli permetteva di essere vicino agli Strozzi ed ai Boiardo.   Epigrafe che ricorda Pico della Mirandola in via del Turco a Ferrara Gli studi e l'attività Pico compì i suoi studi fra Bologna, Pavia, Ferrara, Padova e Firenze; mostrò grandi doti nel campo della matematica e imparò molte lingue, tra cui perfettamente il latino, il greco, l'ebraico, l'aramaico, l'arabo e il francese. Ebbe anche modo di stringere rapporti di amicizia con numerose personalità dell'epoca come Girolamo Savonarola, Marsilio Ficino, Lorenzo il Magnifico, Angelo Poliziano, Egidio da Viterbo, Girolamo Benivieni, Girolamo Balbi, Yohanan Alemanno, Elia del Medigo. A Firenze in particolare entrò a far parte della nuova Accademia Platonica. Nel 1484 si recò a Parigi, ospite della Sorbona, allora centro internazionale di studi teologici, dove conobbe alcuni uomini di cultura come Lefèvre d'Étaples, Robert Gaguin e Georges Hermonyme. Ben presto divenne celebre in tutta Europa e si diceva che avesse una memoria talmente fuori dal comune che conosceva l'intera Divina Commedia a memoria.  Nel 1486 fu a Roma dove preparò 900 tesi in vista di un congresso filosofico universale (per la cui apertura compose il De hominis dignitate), che tuttavia non ebbe mai luogo. Subì infatti alcune accuse di eresia,[3] in seguito alle quali fuggì in Francia dove venne anche arrestato da Filippo II presso Grenoble e condotto a Vincennes, per essere tuttavia subito scarcerato. Con l'assoluzione di papa Alessandro VI, il quale vedeva di buon occhio la volontà di Pico di dimostrare la divinità di Cristo attraverso la magia e la cabala, nonché godendo della rete di protezioni dei Medici, dei Gonzaga e degli Sforza, si stabilì quindi definitivamente a Firenze, continuando a frequentare l'Accademia di Ficino. La morte Morì per avvelenamento[4] da arsenico[5] il 17 Novembre 1494, all'età di trentun anni,[6] mentre Firenze veniva occupata dalle truppe francesi di Carlo VIII[7][8] durante la Guerra d'Italia del 1494-1498. Fu sepolto nel cimitero dei domenicani dentro il convento di San Marco. Le sue ossa saranno rinvenute da padre Chiaroni nel 1933 accanto a quelle di Angelo Poliziano e dell'amico Girolamo Benivieni.  «Siamo vissuti celebri, o Ermolao, e tali vivremo in futuro, non nelle scuole dei grammatici, non là dove si insegna ai ragazzi, ma nelle accolte dei filosofi e nei circoli dei sapienti, dove non si tratta né si discute sulla madre di Andromaca, sui figli di Niobe e su fatuità del genere, ma sui principî delle cose umane e divine.»  (Pico della Mirandola) Nel novembre del 2018, più di 500 anni dopo, uno studio coordinato del dipartimento di Biologia dell'Università di Pisa, del Reparto Investigazioni Scientifiche dell'Arma dei Carabinieri di Parma e di studiosi spagnoli, britannici e tedeschi, ha dimostrato che Pico della Mirandola fu avvelenato con l'arsenico.[5][9]  Fama postuma  Il volto di Giovanni Pico ricostruito con le moderne tecniche forensi Di Pico della Mirandola è rimasta letteralmente proverbiale la prodigiosa memoria: si dice conoscesse a mente numerose opere su cui si fondava la sua vasta cultura enciclopedica, e che sapesse recitare la Divina Commedia al contrario, partendo dall'ultimo verso, impresa che pare gli riuscisse con qualunque poema appena terminato di leggere.[10]  Tutt'oggi è ancora in uso attribuire l'appellativo "Pico della Mirandola" a chiunque sia dotato di ottima memoria.[11]  Secondo una popolare diceria, Pico della Mirandola avrebbe avuto una amante o una concubina segreta[12]; tuttavia, si è sostenuto che potrebbe aver avuto un rapporto amoroso con l'umanista Girolamo Benivieni, sulla base di alcuni scritti, tra cui sonetti, che quest'ultimo aveva dedicato a Pico,[13] e di alcune allusioni poco chiare di Savonarola.[12] Pico era comunque un seguace dell'ideale dell'amor socratico,[12] privo cioè di contenuti erotici e passionali; anche la figura femminile ricorrente nei suoi versi viene celebrata su un piano prevalentemente filosofico.[14]  Ascendenza GenitoriNonniBisnonni Giovanni I PicoFrancesco II PicoGianfrancesco I Pico Caterina BevilacquaGuglielmo BevilacquaTaddea Tarlati Giovanni PicoFeltrino Boiardo Matteo BoiardoBernardina Lambertini.Giulia BoiardoGuiduccia da Correggio Gherardo VI da CorreggioDottrina  Marsilio Ficino, Giovanni Pico della Mirandola e Agnolo Poliziano, ritratti da Cosimo Rosselli nella Cappella del Miracolo del Sacramento a Firenze Il pensiero di Pico della Mirandola si riallaccia al pensiero neoplatonico di Marsilio Ficino, senza però occuparsi della polemica anti-aristotelica. Al contrario, egli cerca di riconciliare aristotelismo e platonismo in una sintesi superiore, fondendovi anche altri elementi culturali e religiosi, come per esempio la tradizione misterica di Ermete Trismegisto e della cabala.[15]  All'interno del testo delle Conclusiones Pico si scaglia duramente contro Ficino, considerando inefficace la sua magia naturale perché carente di un legame con le forze superiori nonché di un'adeguata conoscenza cabalistica.[16]  L'ideale di una filosofia universale Il proposito di Pico, esplicitamente dichiarato ad esempio nel De ente et uno, consiste infatti nel ricostruire i lineamenti di una filosofia universale, che nasca dalla concordia fra tutte le diverse correnti di pensiero sorte sin dall'antichità, accomunate dall'aspirazione al divino e alla sapienza, e culminanti nel messaggio della Rivelazione cristiana. In questo suo ecumenismo filosofico, oltre che religioso, vengono accolti non solo i teologi cristiani ed esoterici insieme a Platone, Aristotele, i neoplatonici e tutto il sapere gnostico ed ermetico proprio della filosofia greca, ma anche il pensiero islamico, quello ebraico e appunto cabbalistico, nonché dei mistici di ogni tempo e luogo.[17]  Il congresso da lui organizzato a Roma in vista di una tale "pace filosofica" avrebbe dovuto inserirsi proprio in questo progetto culturale basato su una concezione della verità come princìpio eterno ed universale, al quale ogni epoca della storia ha saputo attingere in misura in più o meno diversa. In seguito tuttavia ai vari contrasti che gli si presentarono, sorti a causa della difficoltà di una tale conciliazione, Pico si accorse che il suo ideale era difficilmente perseguibile; ad esso, a poco a poco, si sostituirà nella sua mente il proposito riformatore di Girolamo Savonarola, rivolto al rinnovamento morale, più che culturale, della città di Firenze. L'armonia universale da lui ricercata in ambito filosofico si trasformerà così nell'aspirazione religiosa ad una santità e una moralità meno generica e più attinente al suo particolare momento storico. A differenza di Ficino, nel Pico emergono dunque nei suoi ultimi anni un maggiore senso di irrequietezza e una visione più cupa ed esistenziale della vita.[17]  La dignità dell'uomo  Ritratto di Pico della Mirandola eseguito da un anonimo del XVII secolo: xilografia dal libro Della celestiale fisionomia, Padova 1616 Al centro del suo ideale di concordia universale risalta fortemente il tema della dignità e della libertà umana. L'uomo infatti, dice Pico, è l'unica creatura che non ha una natura predeterminata, poiché:  «[...] Già il Sommo Padre, Dio Creatore, aveva foggiato, [...] questa dimora del mondo quale ci appare, [...]. Ma, ultimata l'opera, l'Artefice desiderava che ci fosse qualcuno capace di afferrare la ragione di un'opera così grande, di amarne la bellezza, di ammirarne la vastità. [...] Ma degli archetipi non ne restava alcuno su cui foggiare la nuova creatura, né dei tesori [...] né dei posti di tutto il mondo [...]. Tutti erano ormai pieni, tutti erano stati distribuiti nei sommi, nei medi, negli infimi gradi. [...]»  (Giovanni Pico della Mirandola, Oratio de hominis dignitate,[18] 1486) Dunque, per Pico, l'uomo non ha affatto una natura determinata in un qualche grado (alto o basso), bensì:  «[...] Stabilì finalmente l'Ottimo Artefice che a colui cui nulla poteva dare di proprio fosse comune tutto ciò che aveva singolarmente assegnato agli altri. Perciò accolse l'uomo come opera di natura indefinita e, postolo nel cuore del mondo, così gli parlò: -non ti ho dato, o Adamo, né un posto determinato, né un aspetto proprio, né alcuna prerogativa tua, perché [...] tutto secondo il tuo desiderio e il tuo consiglio ottenga e conservi. La natura limitata degli altri è contenuta entro leggi da me prescritte. Tu te la determinerai senza essere costretto da nessuna barriera, secondo il tuo arbitrio, alla cui potestà ti consegnai. [...]»  (Giovanni Pico della Mirandola, Oratio de hominis dignitate[18]) Pico della Mirandola afferma, in sostanza, che Dio ha posto nell'uomo non una natura determinata, ma una indeterminatezza che è dunque la sua propria natura, e che si regola in base alla volontà, cioè all'arbitrio dell'uomo, che conduce tale indeterminatezza dove vuole.  Pico aggiunge poi:  «[...] Non ti ho fatto né celeste né terreno, né mortale né immortale, perché di te stesso quasi libero e sovrano artefice ti plasmassi e ti scolpissi nella forma che avresti prescelto. Tu potrai degenerare nelle cose inferiori che sono i bruti; tu potrai, secondo il tuo volere, rigenerarti nelle cose superiori che sono divine.- [...] Nell'uomo nascente il Padre ripose semi d'ogni specie e germi d'ogni vita. E a seconda di come ciascuno li avrà coltivati, quelli cresceranno e daranno in lui i loro frutti. [...] se sensibili, sarà bruto, se razionali, diventerà anima celeste, se intellettuali, sarà angelo, e si raccoglierà nel centro della sua unità, fatto uno spirito solo con Dio, [...].»  (Giovanni Pico della Mirandola, Oratio de hominis dignitate[18]) Giovanni Pico, quindi, sostiene che è l'uomo a «forgiare il proprio destino», secondo la propria volontà, e la sua libertà è massima, poiché non è né animale né angelo, ma può essere l'uno o l'altro secondo la «coltivazione» di alcuni tra i «semi d'ogni sorta» che vi sono in lui. Questa visione verrà, seppur solo in parte, ripresa nel 1600 dallo scienziato e filosofo Blaise Pascal, che afferma che l'uomo non è né «angelo né bestia», e che la sua propria posizione nel mondo è un punto mediano tra questi due estremi; tale punto mediano, però, per Pico non è una mediocrità (in parte angelo e in parte bruto) ma è la volontà (o l'arbitrio) che ci consente di scegliere la nostra posizione. Dunque l'uomo, per Pico, è la più dignitosa fra tutte le creature, anche più degli angeli, poiché può scegliere che creatura essere.[19] La sapienza della Cabala  Raffigurazione della Cabala con l'albero della vita Il secondo grande interesse di Pico è rivolto alla cabala, che viene da lui spiegata come una fonte di sapienza a cui attingere per decifrare il mistero del mondo, e nella quale Dio appare oscuro, in quanto apparentemente irraggiungibile dalla ragione; ma l'uomo può ricavare la massima luce da tale oscurità.[20]  (LA) «Nulla est scientia quae nos magis certificat de divinitate Christi, quam Magia et Cabala.»  (IT) «Non esiste alcuna scienza che possa attestare meglio la divinità di Cristo che la magia e la cabala.»  (Giovanni Pico della Mirandola, Novecento tesi[21]) Connessa alla sapienza cabbalistica è la magia: infatti, il mago, per Pico, opererebbe attraverso simboli e metafore di una realtà assoluta che è oltre il visibile, e dunque, partendo dalla natura, può giungere a conoscere tale sfera invisibile (ossia metafisica) attraverso la conoscenza della struttura matematica che è il fondamento simbolico-metaforico della natura stessa.[22]  Critica dell'astrologia Se la magia è giudicata positivamente da Pico della Mirandola, per quanto riguarda invece l'astrologia egli ebbe un atteggiamento diverso, che lo portò a distinguere nettamente tra «astrologia matematica o speculativa», cioè l'astronomia, e l'«astrologia giudiziale o divinatrice»; mentre la prima ci consente di conoscere la realtà armonica dell'universo, e dunque è giusta, la seconda crede di poter sottomettere l'avvenire degli uomini alle congiunture astrali.[23] Partendo dall'affermazione della piena dignità e libertà dell'uomo, che può scegliere cosa essere, Pico muove una forte critica a questo secondo tipo di credenze e di pratiche astrologiche, che costituirebbero una negazione proprio della dignità e della libertà umane.  Secondo Pico, questa scienza astrologica attribuisce erroneamente ai corpi celesti il potere di influire sulle vicende umane (fisiche e spirituali), sottraendo tale potere alla Provvidenza divina e togliendo agli uomini la libertà di scegliere. Egli non nega che un certo influsso vi possa essere, ma mette in guardia contro il pericolo insito nell'astrologia di subordinare il superiore (cioè l'uomo) all'inferiore (ossia la forza astrale). Le vicende dell'esistenza umana sono tanto intrecciate e complesse che non se ne può spiegare la ragione se non attraverso la piena libertà d'arbitrio dell'uomo.   Opera quae exstant omnia di Pico della Mirandola stampata nel 1601 Il suo Disputationes adversus astrologiam divinatricem (tale è il titolo dell'opera a cui Pico si dedicò nell'ultimo periodo della sua vita) rimase incompiuto e come tale fu pubblicato postumo, nel 1494, con il commento di Giovanni Manardo; tuttavia, alcuni concetti base furono ripresi e rielaborati da Girolamo Savonarola nel suo Trattato contra li astrologi.[24]  Opere Ad Hermolaum de genere dicendi philosophorum, (Lettera a Ermolao Barbaro sul modo di parlare dei filosofi), 1485.

pico della mirandola, Gianfranco: Important if unjustly neglected, murdered, Italian philosopher. Giovanni Francesco Pico della Mirandola (1470-1533) è stato un italiano nobile e il filosofo , il nipote di Giovanni Pico della Mirandola . Il suo nome è in genere troncato come Gianfrancesco Pico della Mirandola .   Contenuto  1                           Biografia 2Opere scelte 3Fonti 4Collegamenti esterni Biografia Gianfrancesco era figlio di Galeotto I Pico , signore di Mirandola , e Bianca Maria d'Este , figlia di Niccolò III d'Este .  Come lo zio si dedica principalmente alla filosofia, ma ha reso soggetto alla Bibbia, anche se nei suoi trattati, De monolocale divinae et Humanæ Sapientiæ e in particolare nei sei libri intitolati Examen doctrinæ Vanitatis gentium , si deprezza l'autorità dei filosofi, al di sopra tutti Aristotele . Ha scritto una biografia dettagliata di suo zio, pubblicato nel 1496, e un altro di Girolamo Savonarola , di cui era un seguace.  Avendo osservato i pericoli a cui la società italiana è stata esposta, al momento, ha lanciato un avvertimento in occasione del Concilio Lateranense : Joannis Francisci Pici Oratio ad Leonem X et concilium Lateranense de reformandis Ecclesiæ Moribus (Hagenau, 1512, dedicato a Willibald Pirckheimer ) .  Morì a Mirandola nel 1533, assassinato dal nipote Galeotto , insieme a suo figlio più giovane, Alessandro. L'altro figlio Giantommaso è stato ambasciatore a Papa Clemente VII . Charles B. Schmitt ha scritto:  Mentre Giovanni Pico aveva spesso sostenuto che tutte le filosofie e le religioni hanno raggiunto una parte della verità, Gianfrancesco detto, in effetti, che tutte le religioni e tutte le filosofie - salva la religione cristiana da soli - sono semplici raccolte di falsità confusi e internamente incoerenti. In possesso di un tale punto di vista, si schiera non solo con Savonarola, ma con alcuni dei padri e con i riformatori pure. Su questo punto, era insistente. Il cristianesimo è una realtà auto-sussistente e che ha poco o nulla da guadagnare dalla filosofia, le scienze e le arti. Questa tesi centrale si diffonde attraverso quasi l'intera produzione letteraria di Gianfrancesco. Egli scrive di non lodare o estendere il regno della filosofia, ma di demolirlo.  Steepto  Le opere selezionate De studio di Divinae et humanae philosophiae (1496) Ioannis Pici Mirandulae Vita (1496) De imaginatione (1501) De Providentia Dei (1508) De rerum praenotione (1506-1507) Quaestio de falsitate Astrologiae (ca. 1510) Examen Vanitatis gentium doctrinae, et veritatis Christianae disciplinae (1520) Libro Detto strega o delle illusioni del demonio (1524) Opera Omnia (1573) fonti Wikisource-logo.svg Herbermann, Charles, ed.

pigliucci: important Italian philosopher. Massimo Pigliucci Da Wikipedia, l'enciclopedia libera. Jump to navigationJump to search  Massimo Pigliucci Massimo Pigliucci (Monrovia, 16 gennaio 1964[1]) è un accademico, filosofo, blogger nonché divulgatore scientifico italiano naturalizzato statunitense.  Pigliucci è professore di filosofia al CUNY-City College di New York[2], è stato co-conduttore del podcast Rationally Speaking (Parlando razionalmente)[3] e redattore capo della rivista online Scientia Salon.[4] Pigliucci è un deciso critico della pseudoscienza[5][6] e del creazionismo[7] ed un sostenitore del secolarismo[8] e della educazione scientifica.[9]   Indice 1Biografia 2Pensiero critico e scetticismo scientifico 2.1Rationally Speaking 3Libri 3.1Articoli 4Note 5Voci correlate 6Altri progetti 7Collegamenti esterni Biografia Pigliucci è nato a Monrovia, Liberia, ma è cresciuto a Roma.[1] Ha conseguito il dottorato in genetica all'Università degli Studi di Ferrara, Italia, un Ph. D. in biologia dell'Università del Connecticut e un Ph. D. in filosofia della scienza dall'Università del Tennessee.[10]; è socio di American Association for the Advancement of Science (Associazione americana per l'avanzamento della scienza) e di Committee for Skeptical Inquiry.[1] Pigliucci è stato professore di ecologia e evoluzione all'Università di Stony Brook compiendo ricerche sulla plasticità fenotipica, le interazioni genotipo-ambiente, la selezione naturale e i vincoli imposti sulla selezione naturale da parte del corredo genetico e dello sviluppo degli organismi.[11] Nel 1997, ha ricevuto il premio Theodosius Dobzhansky,[12] conferito annualmente dalla Society for the Study of Evolution (Associazione per lo studio dell'evoluzione)[1]. Come filosofo, si è interessato alla struttura e ai fondamenti della teoria dell'evoluzione, alla relazione tra scienza e filosofia e alla relazione tra la scienza e la religione[10] ed è un sostenitore della sintesi evolutiva estesa.[13]  Pigliucci scrive regolarmente sullo Skeptical Inquirer sui temi di negazionismo o scetticismo del cambiamento climatico, disegno intelligente, pseudoscienza e filosofia.[14] Ha scritto per Philosophy Now e ha un blog intitolato "Rationally Speaking (Parlando razionalmente)". Ha contrastato "i negazionisti dell'evoluzione" (creazionismo della Terra Giovane e sostenitori del disegno intelligente), tra cui i creazionisti della terra giovane Duane Gish e Kent Hovind, i sostenitori del disegno intelligente William Dembski e Jonathan Wells, in molte occasioni.[15][16][17][18]  Pensiero critico e scetticismo scientifico  Michael Shermer, Julia Galef e Massimo Pigliucci durante una registrazione dal vivo a Northeast Conference on Science and Skepticism (Conferenza del nord-est sulla scienza e sullo scetticismo), 2013 Pur essendo ateo,[19] Pigliucci non crede che la scienza richieda di essere atei, se si ammettono due distinzioni: la distinzione tra naturalismo metodologico e naturalismo filosofico e la distinzione tra giudizi di valore e le questioni di fatto. Crede che molti scienziati ed insegnanti di scienze non apprezzino tali differenze.[9] Pigliucci ha criticato gli scrittori Nuovi Atei per aver sostenuto quello che lui considera scientismo (sebbene escluda il filosofo Daniel Dennett da questa accusa).[20] In una discussione del suo libro Answers for Aristotle: How science and philosophy can lead us to a more meaningful life (Risposte per Aristotele: come la scienza e la filosofia possono condurci ad una vita più ricca di significato), Pigliucci ha detto al conduttore del podcast Skepticality, Derek Colanduno, “Aristotele era il primo pensatore antico a prendere sul serio l'idea che hai bisogno di fatti empirici, e che hai bisogno di un approccio basato sull'evidenza nel mondo, e che devi essere in grado di riflettere sul significato di quei fatti....Se vuoi delle risposte a delle domande morali, non chiedi al neurobiologo, non chiedi al biologo dell'evoluzione, chiedi al filosofo.”[21]  Pigliucci descrive la missione degli scettici, facendo riferimento al libro di Carl Sagan Il mondo infestato dai demoni: La scienza e il nuovo oscurantismo dicendo “Ciò che fanno gli scettici è tenere accesa quella candela e cercare di diffonderla il più possibile.”[22] Pigliucci fa parte del consiglio di NYC Skpetics e fa parte del comitato consultivo di Secular Coalition for America (Coalizione secolare per l'America).[8]  Nel 2001, ha preso parte a un dibattito sull'esistenza di Dio con William Lane Craig.[23]  Massimo Pigliucci ha criticato l'articolo di giornale di Papa Francesco intitolato Un dialogo aperto con i non-credenti (An open dialogue with non-believers). Secondo Pigliucci l'articolo assomigliava più ad un monologo che ad un dialogo, e ha indirizzato una risposta personale a Papa Francesco nella quale ha scritto che il papa ha solo offerto ai non-credenti "una riaffermazione di fantasie senza fondamento riguardo a Dio e a suo Figlio...seguite da affermazioni confuse tra il concetto d'amore e di verità, il tutto condito da una significativa dose di revisionismo storico e negazione degli aspetti più brutti della tua Chiesa (noterai che non ho nemmeno menzionato la pedofilia!).”[24]  Rationally Speaking Nell'agosto 2000 Pigliucci ha iniziato una rubrica su internet intitolata Rationally Speaking (Parlando razionalmente). Nell'agosto 2005, la rubrica è diventata un blog,[25] dove ha scritto fino a marzo 2014.[26] Dal 1º febbraio 2010 Pigliucci co-conduce il podcast bi-settimanale Rationally Speaking con Juilia Galef, che ha conosciuto al Northeast Conference on Science and Skepticism (Conferenza del nord-est sulla scienza e sullo scetticismo), tenuta nel settembre 2009.[27] Il podcast è prodotto da New York City skeptics (Scettici della città di New York). Il programma vede la partecipazione di ricercatori, divulgatori scientifici ed insegnanti per presentare libri o discutere di temi di attualità su temi di filosofia e scienza. In una puntata del 2010, Neil deGrasse Tyson descrisse la necessità di finanziare con denaro pubblico i programmi spaziali. La trascrizione della puntata venne poi pubblicata nel libro Space Chronicles (Cronache Spaziali).[28] In un altro episodio Tyson spiegò la propria opinione sul significato di essere ateo, poi commentata in una trasmissione di NPR.[29] Pigliucci ha poi lasciato il podcast per dedicarsi ad altri interessi.[30]  Libri  Copertina di Philosophy of Pseudoscience (EN) Schlichting, Carl e Pigliucci, Massimo, Phenotypic evolution : a reaction norm perspective, Sunderland, Mass., Sinauer, 1998.

pilgrimage: Grice’s pilgrimage. In his pilgrimage towards what he calls the city of Eternal Truth he finds twelve perils – which he lists. The first is Extensionalism (as opposed to Intensionalism – vide intentum -- consequentes rem intellectam: intendere est essentialiter ipsum esse intentio ... quam a concepto sibi adequato: Odint 226; esse intentum est esse non reale: The second is Nominalism (opposite Realism and Conceptualism – Universalism, Abstractionism). It is funny that Grice was criticised for representing each of the perils!The third is Positivism. Opposite to Negativism. Just kidding.  Opposite to anything Sir Freddie Ayer was opposite to!The fourth is Naturalism. Opposite Non-Naturalism. Just joking! But that’s the hateful word brought by G. E. Moore, whom Grice liked (“Some like Witters, but Moore’s MY man.”) The fifth is Mechanism. Opposite Libertarianism, or Finalism, But I guess one likes Libertarianism.The sixth is Phenomenalism. You cannot oppose it to Physicalism, beause that comes next. So this is G. A. Paul (“Is there a problem about sense data?). And the opposite is anything this Scots philosopher was against!The seventh is Reductionism. Opposite Reductivism. Grice was proud to teach J. M. Rountree the distinction between a benevolent reductionist and a malignant eliminationist reductionist. The eighth is physicalism.Opposite metaphysicalism.  The ninth is materialism. Hyleism. Opposite Formalism. Or Immaterialism. The tenth is Empiricism. Opposite Rationalism. The eleventh is Scepticism.Opposite Dogmatism.and the twelfth is functionalism. Opposite Grice! So now let’s order the twelve perils alphabetically. Empiricism. Extensionalism. Functionalism. MaterialismMechanism. Naturalism. Nominalism. Phenomenalism. Positivism. Physicalism. Reductionism. Scepticism. Now let us see how they apply to the theory of the conversational implicaturum and conversation as rational cooperation. Empiricism – Grice is an avowed rationalist.Extensionalism – His main concern is that the predicate in the proposition which is communicated is void, we yield the counterintuitive result that an emissor who communicates that the S is V, where V is vacuous communicates the same thing he would be communicating for any other vacuous predicate V’Functionalism – There is a purely experiential qualia in some emissor communicating that p that is not covered by the common-or-garden variety of functionalism. E.g. “I love myself.” Materialism – rationalism means dealing with a realm of noumena which goes beyond materialismMechanism – rationalism entails end-setting unweighed finality and freedom. Naturalism – communication involves optimality which is beyond naturalism Nominalism – a predicate is an abstractum. Phenomenalism – there is realism which gives priority to the material thing, not the sense datum. A sense datum of an apple does not nourish us. Positivism – an emissor may communicate a value, which is not positivistically reduced to something verifiable. Physicalism – there must be multiple realization, and many things physicalists say sound ‘harsh’ to Grice’s ears (“Smith’s brain being in state C doesn’t have adequate evidence”). Reductionism – We are not eliminating anything. Scepticism – there are dogmas which are derived from paradigm cases, even sophisticated ones.How to introduce the twelve entriesEmpiricism – from Greek empereia – cf. etymology for English ‘experience.’Extensionalism -- extensumFunctionalism – functum. Materialism  -- Mechanism Naturalism Nominalism Phenomenalism Positivism Physicalism Reductionism Scepticism.  this section events are reviewed according to principal scenes of action. Place names appear in the order in which major incidents occur. City of Destruction. The city stands as a symbol of the entire world as it is, with all of its sins, corruptions, and sorrows. No one living there can have any hope of salvation. Convinced that the city is about to be blasted by the wrath of God, Christian flees and sets out alone on a pilgrimage which he hopes will lead him to Mount Zion, to the Celestial City, where he can enjoy eternal life in the happy company of God and the Heavenly Host. Slough of Despond. A swamp, a bog, a quagmire, the first obstacle in Christian's course. Pilgrims are apt to get mired down here by their doubts and fears. After much difficulty and with some providential help, Christian finally manages to flounder across the treacherous bog and is on his way again. Village of Morality. Near the village Christian meets Mr. Worldly Wiseman, who, though not religiously inclined, is a friendly and well-disposed person. He tells Christian that it would be foolish of him to continue his pilgrimage, the end of which could only be hunger, pain, and death. Christian should be a sensible fellow and settle down in the Village of Morality. It would be a good place to raise a family, for living was cheap there and they would have honest, well-behaved people as neighbors — people who lived by the Ten Commandments. More than a little tempted by this, Christian decides that he should at least have a look at Morality. But along the way he is stopped by his friend Evangelist, who berates him sharply for having listened to anything Mr. Worldly Wiseman might have to say. If Christian is seriously interested in saving his soul, he would be well advised to get back as quickly as possible on the path to the Wicket Gate which Evangelist had pointed out to him before. Wicket Gate. Arriving almost out of breath, Christian reads the sign on the gate: "Knock and it shall be opened unto you." He knocks a number of times before arousing the gatekeeper, a "grave person" named Good-will, who comes out to ask what Christian wants. After the latter has explained his mission, he is let through the gate, which opens on the Holy Way, a straight and narrow path leading toward the Celestial City. Christian asks if he can now be relieved of the heavy burden — a sack filled with his sins and woes — that he has been carrying on his back for so long. Good-will replies that he cannot help him, but that if all goes well, Christian will be freed of his burden in due course. Interpreter's House. On Good-will's advice, Christian makes his first stop at the large house of Interpreter, a character symbolizing the Holy Spirit. Interpreter shows his guest a number of "excellent things." These include a portrait of the ideal pastor with the Bible in his hand and a crown of gold on his head; a dusty parlor which is like the human heart before it is cleansed with the Gospel; a sinner in an iron cage, an apostate doomed to suffer the torments of Hell through all eternity; a wall with a fire burning against it. A figure (the Devil himself) is busily throwing water on the fire to put it out. But he would never succeed, Interpreter explains, because the fire represents the divine spirit in the human heart and a figure on the far side of the wall keeps the fire burning brightly by secretly pouring oil on it — "the oil of Christ's Grace." The Cross. Beyond Interpreter's House, Christian comes to the Cross, which stands on higher ground beside the Holy Way. Below it, at the foot of the gentle slope, is an open sepulcher. When Christian stops by the Cross, the burden on his back suddenly slips from his shoulders, rolls down the slope, and falls into the open sepulcher, to be seen no more. As Christian stands weeping with joy, three Shining Ones (angels) appear. They tell him all his sins are now forgiven, give him bright new raiment to replace his old ragged clothes, and hand him a parchment, "a Roll with a seal upon it." For his edification and instruction, Christian is to read the Roll as he goes along, and when he reaches the Pearly Gates, he is to present it as his credentials a sort of passport to Heaven, as it were. Difficulty Hill. The Holy Way beyond the Cross is fenced in with a high wall on either side. The walls have been erected to force all aspiring Pilgrims to enter the Holy Way in the proper manner, through the Wicket Gate. As Christian is passing along, two men — Formalist and Hypocrisy — climb over the wall and drop down beside him. Christian finds fault with this and gives the wall-jumpers a lecture on the dangers of trying shortcuts. They have been successfully taking shortcuts all their lives, the intruders reply, and all will go well this time. Not too pleased with his company, Christian proceeds with Hypocrisy and Formalist to the foot of Difficulty Hill, where three paths join and they must make a choice. One path goes straight ahead up the steep slope of the hill; another goes around the base of the hill to the right; the third, around the hill to the left. Christian argues that the right path is the one leading straight ahead up Difficulty Hill. Not liking the prospect of much exertion, Formalist and Hypocrisy decide to take the easier way on the level paths going around the hill. Both get lost and perish. Halfway up Difficulty Hill, so steep in places that he has to inch forward on hands and knees, Christian comes to a pleasant arbor provided for the comfort of weary Pilgrims. Sitting down to rest, Christian reaches into his blouse and takes out his precious Roll. While reading it, he drops off to sleep, being awakened when he hears a voice saying sternly: "Go to the ant, thou sluggard; consider her ways, and be wise." Jumping up, Christian makes with all speed to the top of the hill, where he meets two Pilgrims coming toward him — Timorous and Mistrust. They have been up ahead, they say, and there are lions there. They are giving up their pilgrimage and returning home, and unsuccessfully try to persuade Christian to come with them. Their report about the lions disturbs Christian, who reaches into his blouse to get his Roll so that he may read it and be comforted. To his consternation, the Roll is not there. Carefully searching along the way, Christian retraces his steps to the arbor, where, as he recalls, he had been reading the Roll when he allowed himself to doze off in "sinful sleep." Not finding his treasure immediately, he sits down and weeps, considering himself utterly undone by his carelessness in losing "his pass into the Celestial City." When in deepest despair, he chances to see something lying half-covered in the grass. It is his precious Roll, which he tucks away securely in his blouse. Having offered a prayer of thanks "to God for directing his eye to the place where it lay," Christian wearily climbs back to the top of Difficulty Hill. From there he sees a stately building and as it is getting on toward dark, hastens there. Palace Beautiful. A narrow path leads off the Holy Way to the lodge in front of Palace Beautiful. Starting up the path, Christian sees two lions, stops, and turns around as if to retreat. The porter at the lodge, Watchful, who has been observing him, calls out that there is nothing to be afraid of if one has faith. The lions are chained, one on either side of the path, and anyone with faith can pass safely between them if he keeps carefully to the middle of the path, which Christian does. Arriving at the lodge, he asks if he can get lodging for the night. The porter, Watchful, replies that he will find out from those in charge of Palace Beautiful. Soon, four virgins come out to the lodge, all of them "grave and beautiful damsels": Discretion, Prudence, Piety, and Charity. Satisfied with Christian's answers to their questions, they invite him in, introduce him to the rest of the family, serve him supper, and assign him to a beautiful bedroom — Peace — for the night. Next morning, the virgins show him the "rarities" of the place: First, the library, filled with ancient documents dating back to the beginning of time; next, the armory, packed with swords, shields, helmets, breastplates, and other things sufficient to equip all servants of the Lord, even if they were as numerous as the stars in the sky. Leading their guest to the roof of the palace, the virgins point to mountains in the distance — the Delectable Mountains, which lie on the way to the Celestial City. Before allowing Christian to depart, the virgins give him arms and armor to protect himself during the next stretch of his journey, which they warn will be dangerous. Valley of Humiliation. Here Christian is attacked and almost overcome by a "foul fiend" named Apollyon — a hideous monster with scales like a fish, wings like a dragon, mouth like a lion, and feet like a bear; flames and smoke belch out of a hole in his belly. Christian, after a painful struggle, wounds the fiend with his sword and drives him off. Valley of the Shadow of Death. This is a wilderness, a land of deserts and pits, inhabited only by yowling hobgoblins and other dreadful creatures. The path here is very narrow, edged on one side by a deep, water-filled ditch in which many have drowned; on the other side, by a treacherous bog. Walking carefully, Christian goes on and soon finds himself close to the open mouth of Hell, the Burning Pit, out of which comes a cloud of noxious fumes, long fingers of fire, showers of sparks, and hideous noises. With flames flickering all around and smoke almost choking him, Christian manages to get through by use of "All-prayer." Nearing the end of the valley, he hears a shout raised by someone up ahead: "Though I walk through the Valley of the Shadow of Death, I will fear none ill, for Thou art with me." As only a Pilgrim could have raised that cry, Christian hastens forward to see who it might be. To his surprise and delight he finds that it is an old friend, Faithful, one of his neighbors in the City of Destruction. Vanity Fair. Happily journeying together, exchanging stories about their adventures and misadventures, the two Pilgrims come to the town of Vanity Fair, through which they must pass. Interested only in commerce and money-making, the town holds a year-round fair at which all kinds of things are bought and sold — "houses, lands, trades, titles, . . . lusts, pleasures, . . . bodies, souls, silver, gold, pearls, precious stones, and what not." Christian and Faithful infuriate the merchandisers by turning up their noses at the wares offered them, saying that they would buy nothing but the Truth. Their presence and their attitude cause a hubbub in the town, which leads the authorities to jail them for disturbing the peace. The prisoners conduct themselves so well that they win the sympathy of many townspeople, producing more strife and commotion in the streets, and the prisoners are held responsible for this, too, though they have done nothing. It is decided to indict them on the charge of disrupting trade, creating dissension, and treating with contempt the customs and laws laid down for the town by its prince, old Beelzebub himself. Brought to trial first, Faithful is convicted and sentenced to be executed in the manner prescribed by the presiding judge, Lord Hate-good. The hapless Faithful is scourged, brutally beaten, lanced with knives, stoned, and then burned to ashes at the stake. Thus, he becomes another of the Christian martyrs assured of enjoying eternal bliss up on high. Doubting Castle and Giant Despair. In a manner only vaguely explained, Christian gets free and goes on his way — but not alone, for he has been joined by Hopeful, a native of Vanity Fair who is fleeing in search of better things. After a few minor adventures, the two reach a sparkling stream, the River of the Water of Life, which meanders through beautiful meadows bright with flowers. For a time the Holy Way follows the river bank but then veers off into rougher ground which is hard on the sore tired feet of the travelers. Wishing there were an easier way, they plod along until they come to another meadow behind a high fence. Having climbed the fence to have a look, Christian persuades Hopeful that they should move over into By-path Meadow, where there is a soft grassy path paralleling theirs. Moving along, they catch up with Vain-confidence, who says that he is bound for the Celestial City and knows the way perfectly. Night comes on, but he continues to push ahead briskly, with Christian and Hopeful following. Suddenly, the latter hear a frightened cry and a loud thud. Vain-confidence has been dashed to pieces by falling into a deep pit dug by the owner of the meadow. Christian and Hopeful retreat, but as they can see nothing in the dark, they decide to lie down in the meadow to pass the night. Next morning, they are surprised and seized by the prince of By-path Meadow, a giant named Despair. Charging them with malicious trespassing, he hauls them to his stronghold, Doubting Castle, and throws them into a deep dark dungeon, where they lie for days without food or drink. At length, Giant Despair appears, beats them almost senseless, and advises them to take their own lives so that he will not have to come back to finish them off himself. When all seems hopeless, Christian suddenly brightens up, "as one half amazed," and exclaims: "What a fool am I, thus to lie in a stinking dungeon when I may as well walk at liberty. I have a key in my bosom called Promise which will (I am persuaded) open any lock in Doubting Castle." Finding that the magic key works, the prisoners are soon out in the open and running as fast as they can to get back onto the Holy Way, where they erect a sign warning other Pilgrims against being tempted by the apparent ease of traveling by way of By-path Meadow. Delectable Mountains. Christian and Hopeful next come to the Delectable Mountains, where they find gardens, orchards, vineyards, and fountains of water. Four shepherds — Experience, Knowledge, Watchful, and Sincere — come to greet them, telling them that the mountains are the Lord's, as are the flocks of sheep grazing there. Having been escorted around the mountains and shown the sights there, the two Pilgrims on the eve of their departure receive from the shepherds a paper instructing them on what to do and what to avoid on the journey ahead. For one thing, they should not lie down and sleep in the Enchanted Ground, for that would be fatal. Country of Beulah. This is a happy land where the sun shines day and night, flowers bloom continuously, and the sweet and pleasant air is filled with bird-song. There is no lack of grain and wine. Christian and Hopeful stop to rest and enjoy themselves here, pleased that the Celestial City is now within sight, which leads them to assume that the way there is now clear. Dark River. Proceeding, they are amazed when they come to the Dark River, a wide, swift-flowing stream. They look around for a bridge or boat on which to cross. A Shining One appears and tells them that they must make their way across as best they can, that fording the river is a test of faith, that those with faith have nothing to fear. Wading into the river, Hopeful finds firm footing, but Christian does not He is soon floundering in water over his head, fearing that he will be drowned, that he will never see "the land that flows with milk and honey." Hopeful helps Christian by holding his head above water, and the two finally achieve the crossing. Celestial City. On the far side of the river, two Shining Ones are waiting for the Pilgrims and take them by the arm to assist them in climbing the steep slope to the Celestial City, which stands on a "mighty hill . . . higher than the clouds." Coming to the gate of the city, built all of precious stones, Christian and Hopeful present their credentials, which are taken to the King (God). He orders the gate to be opened, and the two weary but elated Pilgrims go in, to find that the streets are paved with gold and that along them walk many men with crowns on their heads and golden harps in their hands.

Placitvm -- hedonism, the view that pleasure including the absence of pain is the sole intrinsic good in life. The hedonist may hold that, questions of morality aside, persons inevitably do seek pleasure psychological hedonism; that, questions of psychology aside, morally we should seek pleasure ethical hedonism; or that we inevitably do, and ought to, seek pleasure ethical and psychological hedonism combined. Psychological hedonism itself admits of a variety of possible forms. One may hold, e.g., that all motivation is based on the prospect of present or future pleasure. More plausibly, some philosophers have held that all choices of future actions are based on one’s presently taking greater pleasure in the thought of doing one act rather than another. Still a third type of hedonism  with roots in empirical psychology  is that the attainment of pleasure is the primary drive of a wide range of organisms including human beings and is responsible, through some form of conditioning, for all acquired motivations. Ethical hedonists may, but need not, appeal to some form of psychological hedonism to buttress their case. For, at worst, the truth of some form of psychological hedonism makes ethical hedonism empty or inescapable  but not false. As a value theory a theory of what is ultimately good, ethical hedonism has typically led to one or the other of two conceptions of morally correct action. Both of these are expressions of moral consequentialism in that they judge actions strictly by their consequences. On standard formulations of utilitarianism, actions are judged by the amount of pleasure they produce for all sentient beings; on some formulations of egoist views, actions are judged by their consequences for one’s own pleasure. Neither egoism nor utilitarianism, however, must be wedded to a hedonistic value theory. A hedonistic value theory admits of a variety of claims about the characteristic sources and types of pleasure. One contentious issue has been what activities yield the greatest quantity of pleasure  with prominent candidates including philosophical and other forms of intellectual discourse, the contemplation of beauty, and activities productive of “the pleasures of the senses.” Most philosophical hedonists, despite the popular associations of the word, have not espoused sensual pleasure. Another issue, famously raised by J. S. Mill, is whether such different varieties of pleasure admit of differences of quality as well as quantity. Even supposing them to be equal in quantity, can we say, e.g., that the pleasures of intellectual activity are superior in quality to those of watching sports on television? And if we do say such things, are we departing from strict hedonism by introducing a value distinction not really based on pleasure at all? Most philosophers have found hedonism  both psychological and ethical  exaggerated in its claims. One difficulty for both sorts of hedonism is the hedonistic paradox, which may be put as follows. Many of the deepest and best pleasures of life of love, of child rearing, of work seem to come most often to those who are engaging in an activity for reasons other than pleasure seeking. Hence, not only is it dubious that we always in fact seek or value only pleasure, but also dubious that the best way to achieve pleasure is to seek it. Another area of difficulty concerns happiness  and its relation to pleasure. In the tradition of Aristotle, happiness is broadly understood as something like well-being and has been viewed, not implausibly, as a kind of natural end of all human activities. But ‘happiness’ in this sense is broader than ‘pleasure’, insofar as the latter designates a particular kind of feeling, whereas ‘well-being’ does not. Attributions of happiness, moreover, appear to be normative in a way in which attributions of pleasure are not. It is thought that a truly happy person has achieved, is achieving, or stands to achieve, certain things respecting the “truly important” concerns of human life. Of course, such achievements will characteristically produce pleasant feelings; but, just as characteristically, they will involve states of active enjoyment of activities  where, as Aristotle first pointed out, there are no distinctive feelings of pleasure apart from the doing of the activity itself. In short, the Aristotelian thesis that happiness is the natural end of all human activities, even if it is true, does not seem to lend much support to hedonism  psychological or ethical.

plathegel and ariskant – Hegel, “one of the most influential and systematic of the idealists” (Grice), also well known for his philosophy of history and philosophy of religion. Life and works. Hegel, the eldest of three children, was born in Stuttgart, the son of a minor financial official in the court of the Duchy of Württemberg. His mother died when he was eleven. At eighteen, he began attending the theology seminary or Stift attached to the  at Tübingen; he studied theology and classical languages and literature and became friendly with his future colleague and adversary, Schelling, as well as the great genius of G. Romantic poetry, Hölderlin. In 1793, upon graduation, he accepted a job as a tutor for a family in Bern, and moved to Frankfurt in 1797 for a similar post. In 1799 his father bequeathed him a modest income and the freedom to resign his tutoring job, pursue his own work, and attempt to establish himself in a  position. In 1801, with the help of Schelling, he moved to the  town of Jena, already widely known as the home of Schiller, Fichte, and the Schlegel brothers. After lecturing for a few years, he became a professor in 1805. Prior to the move to Jena, Hegel’s essays had been chiefly concerned with problems in morality, the theory of culture, and the philosophy of religion. Hegel shared with Rousseau and the G. Romantics many doubts about the political and moral implications of the European Enlightenment and modern philosophy in general, even while he still enthusiastically championed what he termed the principle of modernity, “absolute freedom.” Like many, he feared that the modern attack on feudal political and religious authority would merely issue in the reformulation of new internalized and still repressive forms of authority. And he was among that legion of G. intellectuals infatuated with ancient Greece and the superiority of their supposedly harmonious social life, compared with the authoritarian and legalistic character of the Jewish and later Christian religions. At Jena, however, he coedited a journal with Schelling, The Critical Journal of Philosophy, and came to work much more on the philosophic issues created by the critical philosophy or “transcendental idealism” of Kant, and its legacy in the work of Rheinhold, Fichte, and Schelling. His written work became much more influenced by these theoretical projects and their attempt to extend Kant’s search for the basic categories necessary for experience to be discriminated and evaluated, and for a theory of the subject that, in some non-empirical way, was responsible for such categories. Problems concerning the completeness, interrelation, and ontological status of such a categorial structure were quite prominent, along with a continuing interest in the relation between a free, self-determining agent and the supposed constraints of moral principles and other agents. In his early years at Jena especially before Schelling left in 1803, he was particularly preoccupied with this problem of a systematic philosophy, a way of accounting for the basic categories of the natural world and for human practical activity that would ground all such categories on commonly presupposed and logically interrelated, even interdeducible, principles. In Hegel’s terms, this was the problem of the relation between a “Logic” and a “Philosophy of Nature” and “Philosophy of Spirit.” After 1803, however, while he was preparing his own systematic philosophy for publication, what had been planned as a short introduction to this system took on a life of its own and grew into one of Hegel’s most provocative and influential books. Working at a furious pace, he finished hedonistic paradox Hegel, Georg Wilhelm Friedrich 365    AM  365 what would be eventually called The Phenomenology of Spirit in a period of great personal and political turmoil. During the final writing of the book, he had learned that Christina Burkhard would give birth to his illegitimate son. Ludwig was born in February 1807. And he is supposed to have completed the text on October 13, 1807, the day Napoleon’s armies captured Jena. It was certainly an unprecedented work. In conception, it is about the human race itself as a developing, progressively more self-conscious subject, but its content seems to take in a vast, heterogeneous range of topics, from technical issues in empiricist epistemology to the significance of burial rituals. Its range is so heterogeneous that there is controversy to this day about whether it has any overall unity, or whether it was pieced together at the last minute. Adding to the interpretive problem, Hegel often invented his own striking language of “inverted worlds,” “struggles to the death for recognition,” “unhappy consciousness,” “spiritual animal kingdoms,” and “beautiful souls.” Continuing his  career at Jena in those times looked out of the question, so Hegel accepted a job at Bamberg editing a newspaper, and in the following year began an eight-year stint 180816 as headmaster and philosophy teacher at a Gymnasium or secondary school at Nürnberg. During this period, at forty-one, he married the twenty-year-old Marie von Tucher. He also wrote what is easily his most difficult work, and the one he often referred to as his most important, a magisterial two-volume Science of Logic, which attempts to be a philosophical account of the concepts necessary in all possible kinds of account-givings. Finally, in 1816, Hegel was offered a chair in philosophy at the  of Heidelberg, where he published the first of several versions of his Encyclopedia of the Philosophical Sciences, his own systematic account of the relation between the “logic” of human thought and the “real” expression of such interrelated categories in our understanding of the natural world and in our understanding and evaluation of our own activities. In 1818, he accepted the much more prestigious post in philosophy at Berlin, where he remained until his death in 1831. Soon after his arrival in Berlin, he began to exert a powerful influence over G. letters and intellectual life. In 1821, in the midst of a growing political and nationalist crisis in Prussia, he published his controversial book on political philosophy, The Philosophy of Right. His lectures at the  were later published as his philosophy of history, of aesthetics, and of religion, and as his history of philosophy. Philosophy. Hegel’s most important ideas were formed gradually, in response to a number of issues in philosophy and often in response to historical events. Moreover, his language and approach were so heterodox that he has inspired as much controversy about the meaning of his position as about its adequacy. Hence any summary will be as much a summary of the controversies as of the basic position. His dissatisfactions with the absence of a public realm, or any forms of genuine social solidarity in the G. states and in modernity generally, and his distaste with what he called the “positivity” of the orthodox religions of the day their reliance on law, scripture, and abstract claims to authority, led him to various attempts to make use of the Grecian polis and classical art, as well as the early Christian understanding of love and a renewed “folk religion,” as critical foils to such tendencies. For some time, he also regarded much traditional and modern philosophy as itself a kind of lifeless classifying that only contributed to contemporary fragmentation, myopia, and confusion. These concerns remained with him throughout his life, and he is thus rightly known as one of the first modern thinkers to argue that what had come to be accepted as the central problem of modern social and political life, the legitimacy of state power, had been too narrowly conceived. There are now all sorts of circumstances, he argued, in which people might satisfy the modern criterion of legitimacy and “consent” to the use of some power, but not fully understand the terms within which such issues are posed, or assent in an attenuated, resentful, manipulated, or confused way. In such cases they would experience no connection between their individual will and the actual content of the institutions they are supposed to have sanctioned. The modern problem is as much alienation Entfremdung as sovereignty, an exercise of will in which the product of one’s will appears “strange” or “alien,” “other,” and which results in much of modern life, however chosen or willed, being fundamentally unsatisfying. However, during the Jena years, his views on this issue changed. Most importantly, philosophical issues moved closer to center stage in the Hegelian drama. He no longer regarded philosophy as some sort of self-undermining activity that merely prepared one for some leap into genuine “speculation” roughly Schelling’s position and began to champion a unique kind of comprehensive, very determinate reflection on the interrelations among all the various classical alternatives in philosophy. Much more controversially, he also attempted to understand the way in which such relations and transitions were also reflected in the history of the art, politics, and religions of various historical communities. He thus came to think that philosophy should be some sort of recollection of its past history, a realization of the mere partiality, rather than falsity, of its past attempts at a comprehensive teaching, and an account of the centrality of these continuously developing attempts in the development of other human practices.Through understanding the “logic” of such a development, a reconciliation of sorts with the implications of such a rational process in contemporary life, or at least with the potentialities inherent in contemporary life, would be possible. In all such influences and developments, one revolutionary aspect of Hegel’s position became clearer. For while Hegel still frequently argued that the subject matter of philosophy was “reason,” or “the Absolute,” the unconditioned presupposition of all human account-giving and evaluation, and thereby an understanding of the “whole” within which the natural world and human deeds were “parts,” he also always construed this claim to mean that the subject matter of philosophy was the history of human experience itself. Philosophy was about the real world of human change and development, understood by Hegel to be the collective self-education of the human species about itself. It could be this, and satisfy the more traditional ideals because, in one of his most famous phrases, “what is actual is rational,” or because some full account could be given of the logic or teleological order, even the necessity, for the great conceptual and political changes in human history. We could thereby finally reassure ourselves that the way our species had come to conceptualize and evaluate is not finite or contingent, but is “identical” with “what there is, in truth.” This identity theory or Absolute Knowledgemeans that we will then be able to be “at home” in the world and so will have understood what philosophers have always tried to understand, “how things in the broadest possible sense of the term hang together in the broadest possible sense of the term.” The way it all hangs together is, finally, “due to us,” in some collective and historical and “logical” sense. In a much disputed passage in his Philosophy of Religion lectures, Hegel even suggested that with such an understanding, history itself would be over. Several elements in this general position have inspired a good deal of excitement and controversy. To advance claims such as these Hegel had to argue against a powerful, deeply influential assumption in modern thought: the priority of the individual, self-conscious subject. Such an assumption means, for example, that almost all social relations, almost all our bonds to other human beings, exist because and only because they are made, willed into existence by individuals otherwise naturally unattached to each other. With respect to knowledge claims, while there may be many beliefs in a common tradition that we unreflectively share with others, such shared beliefs are also taken primarily to be the result of individuals continuously affirming such beliefs, however implicitly or unreflectively. Their being shared is simply a consequence of their being simultaneously affirmed or assented to by individuals. Hegel’s account requires a different picture, an insistence on the priority of some kind of collective subject, which he called human “spirit” or Geist. His general theory of conceptual and historical change requires the assumption of such a collective subject, one that even can be said to be “coming to self-consciousness” about itself, and this required that he argue against the view that so much could be understood as the result of individual will and reflection. Rather, he tried in many different ways to show that the formation of what might appear to an individual to be his or her own particular intention or desire or belief already reflected a complex social inheritance that could itself be said to be evolving, even evolving progressively, with a “logic” of its own. The completion of such collective attempts at self-knowledge resulted in what Hegel called the realization of Absolute Spirit, by which he either meant the absolute completion of the human attempt to know itself, or the realization in human affairs of some sort of extrahuman transcendence, or full expression of an infinite God. Hegel tried to advance all such claims about social subjectivity without in some way hypostatizing or reifying such a subject, as if it existed independently of the actions and thoughts of individuals. This claim about the deep dependence of individuals on one another even for their very identity, even while they maintain their independence, is one of the best-known examples of Hegel’s attempt at a dialectical resolution of many of the traditional oppositions and antinomies of past thought. Hegel often argued that what appeared to be contraries in philosophy, such as mind/body, freedom/determinism, idealism/materialism, universal/particular, the state/the individual, or even God/man, appeared such incompatible alternatives only because of the undeveloped and so incomplete perspective within which the oppositions were formulated. So, in one of his more famous attacks on such dualisms, human freedom according to Hegel could not be understood coherently as some purely rational self-determination, independent of heteronomous impulses, nor the human being as a perpetual opposition between reason and sensibility. In his moral theory, Kant had argued for the latter view and Hegel regularly returned to such Kantian claims about the opposition of duty and inclination as deeply typical of modern dualism. Hegel claimed that Kant’s version of a rational principle, the “categorical imperative,” was so formal and devoid of content as not to be action-guiding it could not coherently rule in or rule out the appropriate actions, and that the “moral point of view” rigoristically demanded a pure or dutiful motivation to which no human agent could conform. By contrast, Hegel claimed that the dualisms of morality could be overcome in ethical life Sittlichkeit, those modern social institutions which, it was claimed, provided the content or true “objects” of a rational will. These institutions, the family, civil society, and the state, did not require duties in potential conflict with our own substantive ends, but were rather experienced as the “realization” of our individual free will. It has remained controversial what for Hegel a truly free, rational self-determination, continuous with, rather than constraining, our desire for happiness and self-actualization, amounted to. Many commentators have noted that, among modern philosophers, only Spinoza, whom Hegel greatly admired, was as insistent on such a thoroughgoing compatibilism, and on a refusal to adopt the Christian view of human beings as permanently divided against themselves. In his most ambitious analysis of such oppositions Hegel went so far as to claim that, not only could alternatives be shown to be ultimately compatible when thought together within some higher-order “Notion” Begriff that resolved or “sublated” the opposition, but that one term in such opposition could actually be said to imply or require its contrary, that a “positing” of such a notion would, to maintain consistency, require its own “negating,” and that it was this sort of dialectical opposition that could be shown to require a sublation, or Aufhebung a term of art in Hegel that simultaneously means in G. ‘to cancel’, ‘to preserve’, and ‘to raise up’. This claim for a dialectical development of our fundamental notions has been the most severely criticized in Hegel’s philosophy. Many critics have doubted that so much basic conceptual change can be accounted for by an internal critique, one that merely develops the presuppositions inherent in the affirmation of some notion or position or related practice. This issue has especially attracted critics of Hegel’s Science of Logic, where he tries first to show that the attempt to categorize anything that is, simply and immediately, as “Being,” is an attempt that both “negates itself,” or ends up categorizing everything as “Nothing,” and then that this self-negation requires a resolution in the higher-order category of “Becoming.” This analysis continues into an extended argument that purports to show that any attempt to categorize anything at all must ultimately make use of the distinctions of “essence” and “appearance,” and elements of syllogistic and finally Hegel’s own dialectical logic, and both the details and the grand design of that project have been the subject of a good deal of controversy. Unfortunately, much of this controversy has been greatly confused by the popular association of the terms “thesis,” “antithesis,” and “synthesis” with Hegel’s theory of dialectic. These crude, mechanical notions were invented in 1837 by a less-than-sensitive Hegel expositor, Heinrich Moritz Chalybäus, and were never used as terms of art by Hegel. Others have argued that the tensions Hegel does identify in various positions and practices require a much broader analysis of the historical, especially economic, context within which positions are formulated and become important, or some more detailed attention to the empirical discoveries or paradoxes that, at the very least, contribute to basic conceptual change. Those worried about the latter problem have also raised questions about the logical relation between universal and particular implied in Hegel’s account. Hegel, following Fichte, radicalizes a Kantian claim about the inaccessibility of pure particularity in sensations Kant had written that “intuitions without concepts are blind”. Hegel charges that Kant did not draw sufficiently radical conclusions from such an antiempiricist claim, that he should have completely rethought the traditional distinction between “what was given to the mind” and “what the mind did with the given.” By contrast Hegel is confident that he has a theory of a “concrete universal,” concepts that cannot be understood as pale generalizations or abstract representations of given particulars, because they are required for particulars to Hegel, Georg Wilhelm Friedrich Hegel, Georg Wilhelm Friedrich 368    AM  368 be apprehended in the first place. They are not originally dependent on an immediate acquaintance with particulars; there is no such acquaintance. Critics wonder if Hegel has much of a theory of particularity left, if he does not claim rather that particulars, or whatever now corresponds to them, are only interrelations of concepts, and in which the actual details of the organization of the natural world and human history are deduced as conceptual necessities in Hegel’s Encyclopedia. This interpretation of Hegel, that he believes all entities are really the thoughts, expressions, or modes of a single underlying mental substance, and that this mind develops and posits itself with some sort of conceptual necessity, has been termed a panlogicism, a term of art coined by Hermann Glockner, a Hegel commentator in the first half of the twentieth century. It is a much-disputed reading. Such critics are especially concerned with the implications of this issue in Hegel’s political theory, where the great modern opposition between the state and the individual seems subjected to this same logic, and the individual’s true individuality is said to reside in and only in the political universal, the State. Thus, on the one hand, Hegel’s political philosophy is often praised for its early identification and analysis of a fundamental, new aspect of contemporary life  the categorically distinct realm of political life in modernity, or the independence of the “State” from the social world of private individuals engaged in competition and private association “civil society”. But, on the other hand, his attempt to argue for a completion of these domains in the State, or that individuals could only be said to be free in allegiance to a State, has been, at least since Marx, one of the most criticized aspects of his philosophy. Finally, criticisms also frequently target the underlying intention behind such claims: Hegel’s career-long insistence on finding some basic unity among the many fragmented spheres of modern thought and existence, and his demand that this unity be articulated in a discursive account, that it not be merely felt, or gestured at, or celebrated in edifying speculation. PostHegelian thinkers have tended to be suspicious of any such intimations of a whole for modern experience, and have argued that, with the destruction of the premodern world, we simply have to content ourselves with the disconnected, autonomous spheres of modern interests. In his lecture courses these basic themes are treated in wide-ranging accounts of the basic institutions of cultural history. History itself is treated as fundamentally political history, and, in typically Hegelian fashion, the major epochs of political history are claimed to be as they were because of the internal inadequacies of past epochs, all until some final political semiconsciousness is achieved and realized. Art is treated equally developmentally, evolving from symbolic, through “classical,” to the most intensely self-conscious form of aesthetic subjectivity, romantic art. The Lectures on the Philosophy of Religion embody these themes in some of the most controversial ways, since Hegel often treats religion and its development as a kind of picture or accessible “representation” of his own views about the relation of thought to being, the proper understanding of human finitude and “infinity,” and the essentially social or communal nature of religious life. This has inspired a characteristic debate among Hegel scholars, with some arguing that Hegel’s appropriation of religion shows that his own themes are essentially religious if an odd, pantheistic version of Christianity, while others argue that he has so Hegelianized religious issues that there is little distinctively religious left. Influence. This last debate is typical of that prominent in the post-Hegelian tradition. Although, in the decades following his death, there was a great deal of work by self-described Hegelians on the history of law, on political philosophy, and on aesthetics, most of the prominent academic defenders of Hegel were interested in theology, and many of these were interested in defending an interpretation of Hegel consistent with traditional Christian views of a personal God and personal immortality. This began to change with the work of “young Hegelians” such as D. F. Strauss 180874, Feuerbach 180472, Bruno Bauer 180982, and Arnold Ruge 180380, who emphasized the humanistic and historical dimensions of Hegel’s account of religion, rejected the Old Hegelian tendencies toward a reconciliation with contemporary political life, and began to reinterpret and expand Hegel’s account of the productive activity of human spirit eventually focusing on labor rather than intellectual and cultural life. Strauss himself characterized the fight as between “left,” “center,” and “right” Hegelians, depending on whether one was critical or conservative politically, or had a theistic or a humanistic view of Hegelian Geist. The most famous young or left Hegelian was Marx, especially during his days in Paris as coeditor, with Ruge, of the Deutsch-französischen Jahrbücher 1844. Hegel, Georg Wilhelm Friedrich Hegel, Georg Wilhelm Friedrich 369    AM  369 In Great Britain, with its long skeptical, empiricist, and utilitarian tradition, Hegel’s work had little influence until the latter part of the nineteenth century, when philosophers such as Green and Caird took up some of the holistic themes in Hegel and developed a neo-Hegelian reading of issues in politics and religion that began to have influence in the academy. The most prominent of the British neo-Hegelians of the next generation were Bosanquet, McTaggart, and especially Bradley, all of whom were interested in many of the metaphysical implications of Hegel’s idealism, what they took to be a Hegelian claim for the “internally related” interconnection of all particulars within one single, ideal or mental, substance. Moore and Russell waged a hugely successful counterattack in the name of traditional empiricism and what would be called “analytic philosophy” against such an enterprise and in this tradition largely finished off the influence of Hegel or what was left of the historical Hegel in these neo-Hegelian versions. In G.y, Hegel has continued to influence a number of different schools of neo-Marxism, sometimes itself simply called “Hegelian Marxism,” especially the Frankfurt School, or “critical theory” group especially Adorno, Horkheimer, and Marcuse. And he has been extremely influential in France, particularly thanks to the lectures of a brilliant if idiosyncratic Russian émigré, Alexander Kojève, who taught Hegel in the 0s at the École Pratique des Hautes Études to the likes of Merleau-Ponty and Lacan. Kojève was as much influenced by Marx and Heidegger as Hegel, but his lectures inspired many thinkers to turn again to Hegel’s account of human selfdefinition in time and to the historicity of all institutions and practices and so forged an unusual link between Hegel and postwar existentialism. Hegelian themes continue to resurface in contemporary hermeneutics, in “communitarianism” in ethics, and in the increasing attention given to conceptual change and history in the philosophy of science. This has meant for many that Hegel should now be regarded not only as the origin of a distinctive tradition in European philosophy that emphasizes the historical and social nature of human existence, but as a potential contributor to many new and often interdisciplinary approaches to philosophy.


platonic --: Grice: “At Oxford you HAVE to be platonic! Aristotelian is jaded!” -- H. P. Grice as a Platonian commentator – vide his “Metaphysics, Philosophical Eschatology, and Plato’s Republic” -- commentaries on Plato, a term designating the works in the tradition of commentary hypomnema on Plato that may go back to the Old Academy Crantor is attested by Proclus to have been the first to have “commented” on the Timaeus. More probably, the tradition arises in the first century B.C. in Alexandria, where we find Eudorus commenting, again, on the Timaeus, but possibly also if the scholars who attribute to him the Anonymous Theaetetus Commentary are correct on the Theaetetus. It seems also as if the Stoic Posidonius composed a commentary of some sort on the Timaeus. The commentary form such as we can observe in the biblical commentaries of Philo of Alexandria owes much to the Stoic tradition of commentary on Homer, as practiced by the second-century B.C. School of Pergamum. It was normal to select usually consecutive portions of text lemmata for general, and then detailed, comment, raising and answering “problems” aporiai, refuting one’s predecessors, and dealing with points of both doctrine and philology. By the second century A.D. the tradition of Platonic commentary was firmly established. We have evidence of commentaries by the Middle Platonists Gaius, Albinus, Atticus, Numenius, and Cronius, mainly on the Timaeus, but also on at least parts of the Republic, as well as a work by Atticus’s pupil Herpocration of Argos, in twentyfour books, on Plato’s work as a whole. These works are all lost, but in the surviving works of Plutarch we find exegesis of parts of Plato’s works, such as the creation of the soul in the Timaeus 35a36d. The Latin commentary of Calcidius fourth century A.D. is also basically Middle Platonic. In the Neoplatonic period after Plotinus, who did not indulge in formal commentary, though many of his essays are in fact informal commentaries, we have evidence of much more comprehensive exegetic activity. Porphyry initiated the tradition with commentaries on the Phaedo, commentaries on Plato commentaries on Plato 160   160 Cratylus, Sophist, Philebus, Parmenides of which the surviving anonymous fragment of commentary is probably a part, and the Timaeus. He also commented on the myth of Er in the Republic. It seems to have been Porphyry who is responsible for introducing the allegorical interpretation of the introductory portions of the dialogues, though it was only his follower Iamblichus who also commented on all the above dialogues, as well as the Alcibiades and the Phaedrus who introduced the principle that each dialogue should have only one central theme, or skopos. The tradition was carried on in the Athenian School by Syrianus and his pupils Hermeias on the Phaedrus  surviving and Proclus Alcibiades, Cratylus, Timaeus, Parmenides  all surviving, at least in part, and continued in later times by Damascius Phaedo, Philebus, Parmenides and Olympiodorus Alcibiades, Phaedo, Gorgias  also surviving, though sometimes only in the form of pupils’ notes. These commentaries are not now to be valued primarily as expositions of Plato’s thought though they do contain useful insights, and much valuable information; they are best regarded as original philosophical treatises presented in the mode of commentary, as is so much of later Grecian philosophy, where it is not originality but rather faithfulness to an inspired master and a great tradition that is being striven for.  Platonism Platonism -- Damascius c.462c.550, Grecian Neoplatonist philosopher, last head of the Athenian Academy before its closure by Justinian in A.D. 529. Born probably in Damascus, he studied first in Alexandria, and then moved to Athens shortly before Proclus’s death in 485. He returned to Alexandria, where he attended the lectures of Ammonius, but came back again to Athens in around 515, to assume the headship of the Academy. After the closure, he retired briefly with some other philosophers, including Simplicius, to Persia, but left after about a year, probably for Syria, where he died. He composed many works, including a life of his master Isidorus, which survives in truncated form; commentaries on Aristotle’s Categories, On the Heavens, and Meteorologics I all lost; commentaries on Plato’s Alcibiades, Phaedo, Philebus, and Parmenides, which survive; and a surviving treatise On First Principles. His philosophical system is a further elaboration of the scholastic Neoplatonism of Proclus, exhibiting a great proliferation of metaphysical entities.  Platonism -- Eudoxus, Grecian astronomer and mathematician, a student of Plato. He created a test of the equality of two ratios, invented the method of exhaustion for calculating areas and volumes within curved boundaries, and introduced an astronomical system consisting of homocentric celestial spheres. This system views the visible universe as a set of twenty-seven spheres contained one inside the other and each concentric to the earth. Every celestial body is located on the equator of an ideal eudaimonia Eudoxus of Cnidus 291   291 sphere that revolves with uniform speed on its axis. The poles are embedded in the surface of another sphere, which also revolves uniformly around an axis inclined at a constant angle to that of the first sphere. In this way enough spheres are introduced to capture the apparent motions of all heavenly bodies. Aristotle adopted the system of homocentric spheres and provided a physical interpretation for it in his cosmology. R.E.B. Euler diagram, a logic diagram invented by the mathematician Euler that represents standard form statements in syllogistic logic by two circles and a syllogism by three circles. In modern adaptations of Euler diagrams, distributed terms are represented by complete circles and undistributed terms by partial circles circle segments or circles made with dotted lines: Euler diagrams are more perspicuous ways of showing validity and invalidity of syllogisms than Venn diagrams, but less useful as a mechanical test of validity since there may be several choices of ways to represent a syllogism in Euler diagrams, only one of which will show that the syllogism is invalid.  Plato: preeminent Grecian philosopher whose chief contribution consists in his conception of the observable world as an imperfect image of a realm of unobservable and unchanging “Forms,” and his conception of the best life as one centered on the love of these divine objects. Life and influences. Born in Athens to a politically powerful and aristocratic family, Plato came under the influence of Socrates during his youth and set aside his ambitions for a political career after Socrates was executed for impiety. His travels in southern Italy and Sicily brought him into closer contact with the followers of Pythagoras, whose research in mathematics played an important role in his intellectual development. He was also acquainted with Cratylus, a follower of Heraclitus, and was influenced by their doctrine that the world is in constant flux. He wrote in opposition to the relativism of Protagoras and the purely materialistic mode of explanation adopted by Democritus. At the urging of a devoted follower, Dion, he became involved in the politics of Syracuse, the wealthiest city of the Grecian world, but his efforts to mold the ideas of its tyrant, Dionysius II, were unmitigated failures. These painful events are described in Plato’s Letters Epistles, the longest and most important of which is the Seventh Letter, and although the authenticity of the Letters is a matter of controversy, there is little doubt that the author was well acquainted with Plato’s life. After returning from his first visit to Sicily in 387, Plato established the Academy, a fraternal association devoted to research and teaching, and named after the sacred site on the outskirts of Athens where it was located. As a center for political training, it rivaled the school of Isocrates, which concentrated entirely on rhetoric. The bestknown student of the Academy was Aristotle, who joined at the age of seventeen when Plato was sixty and remained for twenty years. Chronology of the works. Plato’s works, many of which take the form of dialogues between Socrates and several other speakers, were composed over a period of about fifty years, and this has led scholars to seek some pattern of philosophical development in them. Increasingly sophisticated stylometric tests have been devised to calculate the linguistic similarities among the dialogues. Ancient sources indicate that the Laws was Plato’s last work, and there is now consensus that many affinities exist between the style of this work and several others, which can therefore also be safely regarded as late works; these include the Sophist, Statesman, and Philebus perhaps written in that order. Stylometric tests also support a rough division of Plato’s other works into early and middle periods. For example, the Apology, Charmides, Crito, Euthyphro, Hippias Minor, Ion, Laches, and Protagoras listed alphabetically are widely thought to be early; while the Phaedo, Symposium, Republic, and Phaedrus perhaps written in that order are agreed to belong to his middle period. But in some cases it is difficult or impossible to tell which of two works belonging to the same general period preceded the other; this is especially true of the early dialogues. The most controversial chronological question concerns the Timaeus: stylometric tests often place it with the later dialogues, though some scholars think that its philosophical doctrines are discarded in the later dialogues, and they therefore assign it to Plato’s middle period. The underlying issue is whether he abandoned some of the main doctrines of this middle period. Early and middle dialogues. The early dialogues typically portray an encounter between Socrates and an interlocutor who complacently assumes that he understands a common evaluative concept like courage, piety, or beauty. For example, Euthyphro, in the dialogue that bears his name, denies that there is any impiety in prosecuting his father, but repeated questioning by Socrates shows that he cannot say what single thing all pious acts have in common by virtue of which they are rightly called pious. Socrates professes to have no answer to these “What is X?” questions, and this fits well with the claim he makes in the Apology that his peculiarly human form of wisdom consists in realizing how little he knows. In these early dialogues, Socrates seeks but fails to find a philosophically defensible theory that would ground our use of normative terms. The Meno is similar to these early dialogues  it asks what virtue is, and fails to find an answer  but it goes beyond them and marks a transition in Plato’s thinking. It raises for the first time a question about methodology: if one does not have knowledge, how is it possible to acquire it simply by raising the questions Socrates poses in the early dialogues? To show that it is possible, Plato demonstrates that even a slave ignorant of geometry can begin to learn the subject through questioning. The dialogue then proposes an explanation of our ability to learn in this way: the soul acquired knowledge before it entered the body, and when we learn we are really recollecting what we once knew and forgot. This bold speculation about the soul and our ability to learn contrasts with the noncommittal position Socrates takes in the Apology, where he is undecided whether the dead lose all consciousness or continue their activities in Hades. The confidence in immortality evident in the Meno is bolstered by arguments given in the Phaedo, Republic, and Phaedrus. In these dialogues, Plato uses metaphysical considerations about the nature of the soul and its ability to learn to support a conception of what the good human life is. Whereas the Socrates of the early dialogues focuses almost exclusively on ethical questions and is pessimistic about the extent to which we can answer them, Plato, beginning with the Meno and continuing throughout the rest of his career, confidently asserts that we can answer Socratic questions if we pursue ethical and metaphysical inquiries together. The Forms. The Phaedo is the first dialogue in which Plato decisively posits the existence of the abstract objects that he often called “Forms” or “Ideas.” The latter term should be used with caution, since these objects are not creations of a mind, but exist independently of thought; the singular Grecian terms Plato often uses to name these abstract objects are eidos and idea. These Forms are eternal, changeless, and incorporeal; since they are imperceptible, we can come to have knowledge of them only through thought. Plato insists that it would be an error to identify two equal sticks with what Equality itself is, or beautiful bodies with what Beauty itself is; after all, he says, we might mistakenly take two equal sticks to be unequal, but we would never suffer from the delusion that Equality itself is unequal. The unchanging and incorporeal Form is the sort of object that is presupposed by Socratic inquiry; what every pious act has in common with every other is that it bears a certain relationship  called “participation”  to one and the same thing, the Form of Piety. In this sense, what makes a pious act pious and a pair of equal sticks equal are the Forms Piety and Equality. When we call sticks equal or acts pious, we are implicitly appealing to a standard of equality or piety, just as someone appeals to a standard when she says that a painted portrait of someone is a man. Of course, the pigment on the canvas is not a man; rather, it is properly called a man because it bears a certain relationship to a very different sort of object. In precisely this way, Plato claims that the Forms are what many of our words refer to, even though they are radically different sorts of objects from the ones revealed to the senses. For Plato the Forms are not merely an unusual item to be added to our list of existing objects. Rather, they are a source of moral and religious inspiration, and their discovery is therefore a decisive turning point in one’s life. This process is described by a fictional priestess named Diotima in the Symposium, a dialogue containing a series of speeches in praise of love and concluding with a remarkable description of the passionate response Socrates inspired in Alcibiades, his most notorious admirer. According to Diotima’s account, those who are in love are searching for something they do not yet understand; whether they realize it or not, they seek the eternal possession of the good, and they can obtain it only through productive activity of some sort. Physical love perpetuates the species and achieves a lower form of immortality, but a more beautiful kind of offspring is produced by those who govern cities and shape the moral characteristics of future generations. Best of all is the kind of love that eventually attaches itself to the Form of Beauty, since this is the most beautiful of all objects and provides the greatest happiness to the lover. One develops a love for this Form by ascending through various stages of emotional attachment and understanding. Beginning with an attraction to the beauty of one person’s body, one gradually develops an appreciation for the beauty present in all other beautiful bodies; then one’s recognition of the beauty in people’s souls takes on increasing strength, and leads to a deeper attachment to the beauty of customs, laws, and systems of knowledge; and this process of emotional growth and deepening insight eventually culminates in the discovery of the eternal and changeless beauty of Beauty itself. Plato’s theory of erotic passion does not endorse “Platonic love,” if that phrase designates a purely spiritual relationship completely devoid of physical attraction or expression. What he insists on is that desires for physical contact be restrained so that they do not subvert the greater good that can be accomplished in human relationships. His sexual orientation like that of many of his Athenian contemporaries is clearly homosexual, and he values the moral growth that can occur when one man is physically attracted to another, but in Book I of the Laws he condemns genital activity when it is homosexual, on the ground that such activity should serve a purely procreative purpose. Plato’s thoughts about love are further developed in the Phaedrus. The lover’s longing for and physical attraction to another make him disregard the norms of commonplace and dispassionate human relationships: love of the right sort is therefore one of four kinds of divine madness. This fourfold classificatory scheme is then used as a model of proper methodology. Starting with the Phaedrus, classification  what Plato calls the “collection and division of kinds”  becomes the principal method to be used by philosophers, and this approach is most fully employed in such late works as the Sophist, Statesman, and Philebus. Presumably it contributed to Aristotle’s interest in categories and biological classification. The Republic. The moral and metaphysical theory centered on the Forms is most fully developed in the Republic, a dialogue that tries to determine whether it is in one’s own best interests to be a just person. It is commonly assumed that injustice pays if one can get away with it, and that just behavior merely serves the interests of others. Plato attempts to show that on the contrary justice, properly understood, is so great a good that it is worth any sacrifice. To support this astonishing thesis, he portrays an ideal political community: there we will see justice writ large, and so we will be better able to find justice in the individual soul. An ideal city, he argues, must make radical innovations. It should be ruled by specially trained philosophers, since their understanding of the Form of the Good will give them greater insight into everyday affairs. Their education is compared to that of a prisoner who, having once gazed upon nothing but shadows in the artificial light of a cave, is released from bondage, leaves the cave, eventually learns to see the sun, and is thereby equipped to return to the cave and see the images there for what they are. Everything in the rulers’ lives is designed to promote their allegiance to the community: they are forbidden private possessions, their sexual lives are regulated by eugenic considerations, and they are not to know who their children are. Positions of political power are open to women, since the physical differences between them and men do not in all cases deprive them of the intellectual or moral capacities needed for political office. The works of poets are to be carefully regulated, for the false moral notions of the traditional poets have had a powerful and deleterious impact on the general public. Philosophical reflection is to replace popular poetry as the force that guides moral education. What makes this city ideally just, according to Plato, is the dedication of each of its components to one task for which it is naturally suited and specially trained. The rulers are ideally equipped to rule; the soldiers are best able to enforce their commands; and the economic class, composed of farmers, craftsmen, builders, and so on, are content to do their work and to leave the tasks of making and enforcing the laws to others. Accordingly what makes the soul of a human being just is the same principle: each of its components must properly perform its own task. The part of us that is capable of understanding and reasoning is the part that must rule; the assertive part that makes us capable of anger and competitive spirit must give our understanding the force it needs; and our appetites for food and sex must be trained so that they seek only those objects that reason approves. It is not enough to educate someone’s reason, for unless the emotions and appetites are properly trained they will overpower it. Just individuals are those who have fully integrated these elements of the soul. They do not unthinkingly follow a list of rules; rather, their just treatment of others flows from their own balanced psychological condition. And the paradigm of a just person is a philosopher, for reason rules when it becomes passionately attached to the most intelligible objects there are: the Forms. It emerges that justice pays because attachment to these supremely valuable objects is part of what true justice of the soul is. The worth of our lives depends on the worth of the objects to which we devote ourselves. Those who think that injustice pays assume that wealth, domination, or the pleasures of physical appetite are supremely valuable; their mistake lies in their limited conception of what sorts of objects are worth loving. Late dialogues. The Republic does not contain Plato’s last thoughts on moral or metaphysical matters. For example, although he continues to hold in his final work, the Laws, that the family and private wealth should ideally be abolished, he describes in great detail a second-best community that retains these and many other institutions of ordinary political life. The sovereignty of law in such a state is stressed continually; political offices are to be filled by elections and lots, and magistrates are subject to careful scrutiny and prosecution. Power is divided among several councils and offices, and philosophical training is not a prerequisite for political participation. This second-best state is still worlds apart from a modern liberal democracy  poetic works and many features of private life are carefully regulated, and atheism is punished with death  but it is remarkable that Plato, after having made no concessions to popular participation in the Republic, devoted so much energy to finding a proper place for it in his final work. Plato’s thoughts about metaphysics also continued to evolve, and perhaps the most serious problem in interpreting his work as a whole is the problem of grasping the direction of these further developments. One notorious obstacle to understanding his later metaphysics is presented by the Parmenides, for here we find an unanswered series of criticisms of the theory of Forms. For example, it is said that if there is reason to posit one Form of Largeness to select an arbitrary example then there is an equally good reason to posit an unlimited number of Forms of this type. The “first” Form of Largeness must exist because according to Plato whenever a number of things are large, there is a Form of Largeness that makes them large; but now, the argument continues, if we consider this Form together with the other large things, we should recognize still another Form, which makes the large things and Largeness itself large. The argument can be pursued indefinitely, but it seems absurd that there should be an unlimited number of Forms of this one type. In antiquity the argument was named the Third Man, because it claims that in addition to a second type of object called “man”  the Form of Man  there is even a third. What is Plato’s response to this and other objections to his theory? He says in the Parmenides that we must continue to affirm the existence of such objects, for language and thought require them; but instead of responding directly to the criticisms, he embarks on a prolonged examination of the concept of unity, reaching apparently conflicting conclusions about it. Whether these contradictions are merely apparent and whether this treatment of unity contains a response to the earlier critique of the Forms are difficult matters of interpretation. But in any case it is clear that Plato continues to uphold the existence of unchanging realities; the real difficulty is whether and how he modifies his earlier views about them. In the Timaeus, there seem to be no modifications at all  a fact that has led some scholars to believe, in spite of some stylometric evidence to the contrary, that this work was written before Plato composed the critique of the Forms in the Parmenides. This dialogue presents an account of how a divine but not omnipotent craftsman transformed the disorderly materials of the universe into a harmonious cosmos by looking to the unchanging Forms as paradigms and creating, to the best of his limited abilities, constantly fluctuating images of those paradigms. The created cosmos is viewed as a single living organism governed by its own divinely intelligent soul; time itself came into existence with the cosmos, being an image of the timeless nature of the Forms; space, however, is not created by the divine craftsman but is the characterless receptacle in which all change takes place. The basic ingredients of the universe are not earth, air, fire, and water, as some thinkers held; rather, these elements are composed of planes, which are in turn made out of elementary triangular shapes. The Timaeus is an attempt to show that although many other types of objects besides the Forms must be invoked in order to understand the orderly nature of the changing universe  souls, triangles, space  the best scientific explanations will portray the physical world as a purposeful and very good approximation to a perfect pattern inherent in these unchanging and eternal objects. But Forms do not play as important a role in the Philebus, a late dialogue that contains Plato’s fullest answer to the question, What is the good? He argues that neither pleasure not intelligence can by itself be identified with the good, since no one would be satisfied with a life that contained just one of these but totally lacked the other. Instead, goodness is identified with proportion, beauty, and truth; and intelligence is ranked a superior good to pleasure because of its greater kinship to these three. Here, as in the middle dialogues, Plato insists that a proper understanding of goodness requires a metaphysical grounding. To evaluate the role of pleasure in human life, we need a methodology that applies to all other areas of understanding. More specifically, we must recognize that everything can be placed in one of four categories: the limited, the unlimited, the mixture of these two, and the intelligent creation of this mixture. Where Forms are to be located in this scheme is unclear. Although metaphysics is invoked to answer practical questions, as in the Republic, it is not precisely the same metaphysics as before. Though we naturally think of Plato primarily as a writer of philosophical works, he regards the written word as inferior to spoken interchange as an instrument for learning and teaching. The drawbacks inherent in written composition are most fully set forth in the Phaedrus. There is no doubt that in the Academy he participated fully in philosophical debate, and on at least one occasion he lectured to a general audience. We are told by Aristoxenus, a pupil of Aristotle, that many in Plato’s audience were baffled and disappointed by a lecture in which he maintained that Good is one. We can safely assume that in conversation Plato put forward important philosophical ideas that nonetheless did not find their way into his writings. Aristotle refers in Physics IV.2 to one of Plato’s doctrines as unwritten, and the enigmatic positions he ascribes to Plato in Metaphysics I.6  that the Forms are to be explained in terms of number, which are in turn generated from the One and the dyad of great and small  seem to have been expounded solely in discussion. Some scholars have put great weight on the statement in the Seventh Letter that the most fundamental philosophical matters must remain unwritten, and, using later testimony about Plato’s unwritten doctrines, they read the dialogues as signs of a more profound but hidden truth. The authenticity of the Seventh Letter is a disputed question, however. In any case, since Aristotle himself treats the middle and late dialogues as undissembling accounts of Plato’s philosophy, we are on firm ground in adopting the same approach. Cf. Plato and Platonism by Pater, an early philosophical reading by Grice. Refs.: H. P. Grice, “Commentary on Plato’s Republic,” H. P. Grice, “Semantics as footnotes to Cratylus.” H. P. Grice, “Plato and Cassirer, Aristotle and I.” Luigi Speranza, “The Aristotle-Plato polemic at Oxford and how Grice suffered iit.”

playgroup: Grice: “Strictly, a playgroup is institutional – I wouldn’t say that Tom and Jerry form a playgroup if they played chess together only once!” -- The motivation for the three playgroups were different. Austin’s first playgroup was for fun. Grice never attended. Austin’s new playgroup, or ‘second’ playgroup, if you must, was a sobriquet Grice gave because it was ANYTHING BUT. Grice’s playgroup upon Austin’s death was for fun, like the ‘first’ playgroup. Since Grice participated in the second and third, he expanded. The second playgroup was for ‘philosophical hacks’ who needed ‘para-philosophy.’ The third playgroup was for fun fun. While Austin belonged to the first and the second playgroups, there were notorious differences. In the first playgroup, he was not the master, and his resentment towards Ayer can be seen in “Sense and Sensibilia.” The second playgroup had Austin as the master. It is said that the playgroup survived Austin’s demise with Grice’s leadership – But Grice’s playgroup was still a different thing – some complained about the disorderly and rambling nature – Austin had kept a very tidy organisation and power structure. Since Grice does NOT mention his own playgroup, it is best to restrict playgroup as an ironic sobriquet by Grice to anything but a playgroup, conducted after the war by Austin, by invitation only, to full-time university lecturers in philosophy. Austin would hold a central position, and Austin’s motivation was to ‘reach’ agreement. Usually, when agreement was not reached, Austin could be pretty impolite. Grice found himself IN THE PLAYGROUP. He obviously preferred a friendlier atmosphere, as his own group later testified. But he was also involved in philosophical activity OTHER than the play group. Notably his joint endeavours with Strawson, Warnock, Pears, and Thomson. For some reason he chose each for a specific area: Warnock for the philosophy of perception (Grice’s implicaturum is that he would not explore meta-ethics with Warnock – he wouldn’t feel like, nor Warnock would). Philosophy of action of all things, with J. F. Thomson. Philosophical psychology with D. F. Pears – so this brings Pears’s observations on intending, deciding, predicting, to the fore. And ontology with P. F. Strawson. Certainlty he would not involve with Strawson on endless disagreements about the alleged divergence or lack thereof between truth-functional devices and their vernacular counterparts! Grice also mentions collaboration with Austin in teaching – “an altogether flintier experience,” as Warnock knows and “Grice can testify.” – There was joint seminars with A. M. Quinton, and a few others. One may add the tutorials. Some of his tutees left Griceian traces: A. G. N. Flew, David Bostock, J. L. Ackrill, T. C. Potts.  The term was meant ironically. The playgroup activities smack of military or civil service!  while this can be safely called Grice’s playgroup, it was founded by Austin at All Souls, where it had only seven members. After the war, Grice joined in. The full list is found elsewhere. With Austin’s death, Grice felt the responsibility to continue with it, and plus, he enjoyed it! In alphabetical order. It is this group that made history.  J. L. Austin, A. G. N. Flew, P. L. Gardiner, H. P. Grice, S. N. Hampshire, R. M. Hare, H. L. A. Hart,  P. H. Nowell-Smith, G. A. Paul, D. F. Pears, P. F. Strawson, J. F. Thomson, J. O. Urmson, G. J. Warnock, A. D. Woozley. Grice distinguishes it very well from Ryle’s group, and the group of neo-Wittgensteinians. And those three groups were those only involved with ‘ordinary language.’

plotino: Greco-Roman Neoplatonist philosopher. Born in Egypt, though doubtless of Grecian ancestry, and thus “more of a Roman than a ‘gypsy’”– Grice – Plotinus studied Platonic philosophy in Alexandria with Ammonius Saccas 23243; then, after a brief adventure on the staff of the Emperor Gordian III on an unsuccessful expedition against the Persians, he came to Rome in 244 and continued teaching philosophy there until his death. He enjoyed the support of many prominent people, including even the Emperor Gallienus and his wife. His chief pupils were Amelius and Porphyry, the latter of whom collected and edited his philosophical essays, the Enneads so called because arranged by Porphyry in six groups of nine. The first three groups concern the physical world and our relation to it, the fourth concerns Soul, the fifth Intelligence, and the sixth the One. Porphyry’s arrangement is generally followed today, though a chronological sequence of tractates, which he also provides in his introductory Life of Plotinus, is perhaps preferable. The most important treatises are I.1; I.2; I.6; II.4; II.8; III.23; III.6; III.7; IV.34; V.1; V.3; VI.45; VI.7; VI.8; VI.9; and the group III.8, V.8, V.5, and II.9 a single treatise, split up by Porphyry, that is a wide-ranging account of Plotinus’s philosophical position, culminating in an attack on gnosticism. Plotinus saw himself as a faithful exponent of Plato see especially Enneads V.1, but he is far more than that. Platonism had developed considerably in the five centuries that separate Plato from Plotinus, taking on much from both Aristotelianism and Stoicism, and Plotinus is the heir to this process. He also adds much himself.  Grice was fascinated by Plotinus’s use of ‘hyper,’ or supra. If God is hyper-good, that does mean that he is not good? For Grice, Plotinus means ‘hyper’ implicaturally. So, if God is hypergood, this does  not yield the negation that God is good. Only that if Plotinus KNOWS that God is hyper-good he is right in thus saying, but he would never reprimand his co-conversationalists were he to say that God is good.

pluralism: -- versus singularism, dualigm, bi-dualism, and monism – the one and the many --  a philosophical perspective on the world that emphasizes diversity rather than homogeneity, multiplicity rather than unity, difference rather than sameness. The philosophical consequences of pluralism were addressed by Grecian antiquity in its preoccupation with the problem of the one and the many. The proponents of pluralism, represented principally by Empedocles, Anaxagoras, and the Atomists Leucippus and Democritus, maintained that reality was made up of a multiplicity of entities. Adherence to this doctrine set them in opposition to the monism of the Eleatic School Parmenides, which taught that reality was an impermeable unity and an unbroken solidarity. It was thus that pluralism came to be defined as a philosophical alternative to monism. In the development of Occidental thought, pluralism came to be contrasted not only with monism but also with dualism, the philosophical doctrine that there are two, and only two, kinds of existents. Descartes, with his doctrine of two distinct substances  extended non-thinking substance versus non-extended thinking substance  is commonly regarded as having provided the clearest example of philosophical dualism. Pluralism thus needs to be understood as marking out philosophical alternatives to both monism and dualism. Pluralism as a metaphysical doctrine requires that we distinguish substantival from attributive pluralism. Substantival pluralism views the world as containing a multiplicity of substances that remain irreducible to each other. Attributive pluralism finds the multiplicity of kinds not among the furniture of substances that make up the world but rather among a diversity of attributes and distinguishing properties. However, pluralism came to be defined not only as a metaphysical doctrine but also as a regulative principle of explanation that calls upon differing explanatory principles and conceptual schemes to account for the manifold events of nature and the varieties of human experience. Recent philosophical thought has witnessed a resurgence of interest in pluralism. This was evident in the development of  pragmatism, where pluralism received piquant expression in James’s A Pluralistic Universe 9. More recently pluralism was given a voice in the thought of the later Vitters, with its heavy accent on the plurality of language games displayed in our ordinary discourse. Also, in the current developments of philosophical postmodernism Jean-François Lyotard, one finds an explicit pluralistic orientation. Here the emphasis falls on the multiplicity of signifiers, phrase regimens, genres of discourse, and narrational strategies. The alleged unities and totalities of thought, discourse, and action are subverted in the interests of reclaiming the diversified and heterogeneous world of human experience. Pluralism in contemporary thought initiates a move into a postmetaphysical age. It is less concerned with traditional metaphysical and epistemological issues, seeking answers to questions about the nature and kinds of substances and attributes; and it is more attuned to the diversity of social practices and the multiple roles of language, discourse, and narrative in the panoply of human affairs. 

singular-dual-bidual-plural quartet, the: pluralitive logic, also called pleonetetic logic, the logic of ‘many’, ‘most’, ‘few’, and similar terms including ‘four out of five’, ‘over 45 percent’ and so on. Consider 1 ‘Almost all F are G’ 2 ‘Almost all F are not G’ 3 ‘Most F are G’ 4 ‘Most F are not G’ 5 ‘Many F are G’ 6 ‘Many F are not G’ 1 i.e., ‘Few F are not G’ and 6 are contradictory, as are 2 and 5 and 3 and 4. 1 and 2 cannot be true together i.e., they are contraries, nor can 3 and 4, while 5 and 6 cannot be false together i.e., they are subcontraries. Moreover, 1 entails 3 which entails 5, and 2 entails 4 which entails 6. Thus 16 form a generalized “square of opposition” fitting inside the standard one. Sometimes 3 is said to be true if more than half the F’s are G, but this makes ‘most’ unnecessarily precise, for ‘most’ does not literally mean ‘more than half’. Although many pluralitive terms are vague, their interrelations are logically precise. Again, one might define ‘many’ as ‘There are at least n’, for some fixed n, at least relative to context. But this not only erodes the vagueness, it also fails to work for arbitrarily large and infinite domains. ‘Few’, ‘most’, and ‘many’ are binary quantifiers, a type of generalized quantifier. A unary quantifier, such as the standard quantifiers ‘some’ and ‘all’, connotes a second-level property, e.g., ‘Something is F’ means ‘F has an instance’, and ‘All F’s are G’ means ‘F and not G has no instance’. A generalized quantifier connotes a second-level relation. ‘Most F’s are G’ connotes a binary relation between F and G, one that cannot be reduced to any property of a truth-functional compound of F and G. In fact, none of the standard pluralitive terms can be defined in first-order logic. Grice lists (x) and (Ex) as “all” and “the,” and of course (Ex), “some (at least one).” So his approach welcomes the pluralitive logic – o pleonetetic. There may be a scale, as Urmson calls it, involving ‘few’ and ‘most.’ ‘Many’ may bring many a trick. Quine deals with numerical quantifiers, in “The logical form of ‘The apostles were twelve.” – In Grice, this is a clear case of what he calls the principle of conversational fortitude: in a scale (alla Urmson) involving a and b, the conversationalist’s preference for one item in the ordered pair yields that the utterer implicates the negation of the other item. These implicatura are defeasible. Refs.: Luigi Speranza, “Grice and Altham on Geach’s pleoretetics, with and without implicatura.”

Causans – causaturum -- Causatum: plurality of causes, as used by Mill, more than one cause of a single effect; i.e., tokens of different event types causing different tokens of the same event type. Plurality of causes is distinct from overdetermination of an event by more than one actual or potential token cause. For example, an animal’s death has a plurality of causes: it may die of starvation, of bleeding, of a blow to the head, and so on. Mill thought these cases were important because he saw that the existence of a plurality of causes creates problems for his four methods for determining causes. Mill’s method of agreement is specifically vulnerable to the problem: the method fails to reveal the cause of an event when the event has more than one type of cause, because the method presumes that causes are necessary for their effects. Actually, plurality of causes is a commonplace fact about the world because very few causes are necessary for their effects. Unless the background conditions are specified in great detail, or the identity of the effect type is defined very narrowly, almost all cases involve a plurality of causes. For example, flipping the light switch is a necessary cause of the light’s going on, only if one assumes that there will be no short circuit across the switch, that the wiring will remain as it is, and so on, or if one assumes that by ‘the light’s going on’ one means the light’s going on in the normal way. 

poiesis Grecian, ‘production’, behavior aimed at an external end. In Aristotle, poiesis is opposed to praxis action. It is characteristic of crafts  e.g. building, the end of which is houses. It is thus a kinesis process. For Aristotle, exercising the virtues, since it must be undertaken for its own sake, cannot be poiesis. The knowledge involved in virtue is therefore not the same as that involved in crafts. R.C. Grice, who liked opera, was fascinated by the history of the Bardi camerata, and their idea of the ‘melopea,’ or music making.

polarity, the relation between distinct phenomena, terms, or concepts such that each inextricably requires, though it is opposed to, the other, as in the relation between the north and south poles of a magnet. In application to terms or concepts, polarity entails that the meaning of one involves the meaning of the other. This is conceptual polarity. Terms are existentially polar provided an instance of one cannot exist unless there exists an instance of the other. The second sense implies the first. Supply and demand and good and evil are instances of conceptual polarity. North and south and buying and selling are instances of existential polarity. Some polar concepts are opposites, such as truth and falsity. Some are correlative, such as question and answer: an answer is always an answer to a question; a question calls for an answer, but a question can be an answer, and an answer can be a question. The concept is not restricted to pairs and can be extended to generate mutual interdependence, multipolarity.

civis -- political philosophy, the study of the nature and justification of coercive institutions. Coercive institutions range in size from the family to the nation-state and world organizations like the United Nations. They are institutions that at least sometimes employ force or the threat of force to control the behavior of their members. Justifying such coercive institutions requires showing that the authorities within them have a right to be obeyed and that their members have a corresponding obligation to obey them, i.e., that these institutions have legitimate political authority over their members. Classical political philosophers, like Plato and Aristotle, were primarily interested in providing a justification for city-states like Athens or Sparta. But historically, as larger coercive institutions became possible and desirable, political philosophers sought to justify them. After the seventeenth century, most political philosophers focused on providing a justification for nationstates whose claim to legitimate authority is restricted by both geography and nationality. But from time to time, and more frequently in the nineteenth and twentieth centuries, some political philosophers have sought to provide a justification for various forms of world government with even more extensive powers than those presently exercised by the United Nations. And quite recently, feminist political philosophers have raised important challenges to the authority of the family as it is presently constituted. Anarchism from Grecian an archos, ‘no government’ rejects this central task of political philosophy. It maintains that no coercive institutions are justified. Proudhon, the first self-described anarchist, believed that coercive institutions should be replaced by social and economic organizations based on voluntary contractual agreement, and he advocated peaceful change toward anarchism. Others, notably Blanqui and Bakunin, advocated the use of violence to destroy the power of coercive institutions. Anarchism inspired the anarcho-syndicalist movement, Makhno and his followers during the Russian Civil War, the  anarchists during the  Civil War, and the anarchist gauchistes during the 8 “May Events” in France. Most political philosophers, however, have sought to justify coercive institutions; they have simply disagreed over what sort of coercive institutions are justified. Liberalism, which derives from the work of Locke, is the view that coercive institutions are justified when they promote liberty. For Locke, liberty requires a constitutional monarchy with parliamentary government. Over time, however, the ideal of liberty became subject to at least two interpretations. The view that seems closest to Locke’s is classical liberalism, which is now more frequently called political libertarianism. This form of liberalism interprets constraints on liberty as positive acts i.e., acts of commission that prevent people from doing what they otherwise could do. According to this view, failing to help people in need does not restrict their liberty. Libertarians maintain that when liberty is so interpreted only a minimal or night-watchman state that protects against force, theft, and fraud can be justified. In contrast, in welfare liberalism, a form of liberalism that derives from the work of T. H. Green, constraints on liberty are interpreted to include, in addition, negative acts i.e., acts of omission that prevent people from doing what they otherwise could do. According to this view, failing to help people in need does restrict their liberty. Welfare liberals maintain that when liberty is interpreted in this fashion, coercive institutions of a welfare state requiring a guaranteed social minimum and equal opportunity are justified. While no one denies that when liberty is given a welfare liberal interpretation some form of welfare state is required, there is considerable debate over whether a minimal state is required when liberty is given a libertarian interpretation. At issue is whether the liberty of the poor is constrained when they are prevented from taking from the surplus possessions of the rich what they need for survival. If such prevention does constrain the liberty of the poor, it could be argued that their liberty should have priority over the liberty of the rich not to be interfered with when using their surplus possessions for luxury purposes. In this way, it could be shown that even when the ideal of liberty is given a libertarian interpretation, a welfare state, rather than a minimal state, is justified. Both libertarianism and welfare liberalism are committed to individualism. This view takes the rights of individuals to be basic and justifies the actions of coercive institutions as promoting those rights. Communitarianism, which derives from the writings of Hegel, rejects individualism. It maintains that rights of individuals are not basic and that the collective can have rights that are independent of and even opposed to what liberals claim are the rights of individuals. According to communitarians, individuals are constituted by the institutions and practices of which they are a part, and their rights and obligations derive from those same institutions and practices. Fascism is an extreme form of communitarianism that advocates an authoritarian state with limited rights for individuals. In its National Socialism Nazi variety, fascism was also antiSemitic and militarist. In contrast to liberalism and communitarianism, socialism takes equality to be the basic ideal and justifies coercive institutions insofar as they promote equality. In capitalist societies where the means of production are owned and controlled by a relatively small number of people and used primarily for their benefit, socialists favor taking control of the means of production and redirecting their use to the general welfare. According to Marx, the principle of distribution for a socialist society is: from each according to ability, to each according to needs. Socialists disagree among themselves, however, over who should control the means of production in a socialist society. In the version of socialism favored by Lenin, those who control the means of production are to be an elite seemingly differing only in their ends from the capitalist elite they replaced. In other forms of socialism, the means of production are to be controlled democratically. In advanced capitalist societies, national defense, police and fire protection, income redistribution, and environmental protection are already under democratic control. Democracy or “government by the people” is thought to apply in these areas, and to require some form of representation. Socialists simply propose to extend the domain of democratic control to include control of the means of production, on the ground that the very same arguments that support democratic control in these recognized areas also support democratic control of the means of production. In addition, according to Marx, socialism will transform itself into communism when most of the work that people perform in society becomes its own reward, making differential monetary reward generally unnecessary. Then distribution in society can proceed according to the principle, from each according to ability, to each according to needs. It so happens that all of the above political views have been interpreted in ways that deny that women have the same basic rights as men. By contrast, feminism, almost by definition, is the political view that women and men have the same basic rights. In recent years, most political philosophers have come to endorse equal basic rights for women and men, but rarely do they address questions that feminists consider of the utmost importance, e.g., how responsibilities and duties are to be assigned in family structures. Each of these political views must be evaluated both internally and externally by comparison with the other views. Once this is done, their practical recommendations may not be so different. For example, if welfare liberals recognize that the basic rights of their view extend to distant peoples and future generations, they may end up endorsing the same degree of equality socialists defend. Whatever their practical requirements, each of these political views justifies civil disobedience, even revolution, when certain of those requirements have not been met. Civil disobedience is an illegal action undertaken to draw attention to a failure by the relevant authorities to meet basic moral requirements, e.g., the refusal of Rosa Parks to give up her seat in a bus to a white man in accord with the local ordinance in Montgomery, Alabama, in 5. Civil disobedience is justified when illegal action of this sort is the best way to get the relevant authorities to bring the law into better correspondence with basic moral requirements. By contrast, revolutionary action is justified when it is the only way to correct a radical failure of the relevant authorities to meet basic moral requirements. When revolutionary action is justified, people no longer have a political obligation to obey the relevant authorities; that is, they are no longer morally required to obey them, although they may still continue to do so, e.g. out of habit or fear. Recent contemporary political philosophy has focused on the communitarianliberal debate. In defense of the communitarian view, Alasdair MacIntyre has argued that virtually all forms of liberalism attempt to separate rules defining right action from conceptions of the human good. On this account, he contends, these forms of liberalism must fail because the rules defining right action cannot be adequately grounded apart from a conception of the good. Responding to this type of criticism, some liberals have openly conceded that their view is not grounded independently of some conception of the good. Rawls, e.g., has recently made clear that his liberalism requires a conception of the political good, although not a comprehensive conception of the good. It would seem, therefore, that the debate between communitarians and liberals must turn on a comparative evaluation of their competing conceptions of the good. Unfortunately, contemporary communitarians have not yet been very forthcoming about what particular conception of the good their view requires. 

res publica: -- political theory, reflection concerning the empirical, normative, and conceptual dimensions of political life. There are no topics that all political theorists do or ought to address, no required procedures, no doctrines acknowledged to be authoritative. The meaning of ‘political theory’ resides in its fluctuating uses, not in any essential property. It is nevertheless possible to identify concerted tendencies among those who have practiced this activity over twenty-five centuries. Since approximately the seventeenth century, a primary question has been how best to justify the political rule of some people over others. This question subordinated the issue that had directed and organized most previous political theory, namely, what constitutes the best form of political regime. Assuming political association to be a divinely ordained or naturally necessary feature of the human estate, earlier thinkers had asked what mode of political association contributes most to realizing the good for humankind. Signaling the variable but intimate relationship between political theory and political practice, the change in question reflected and helped to consolidate acceptance of the postulate of natural human equality, the denial of divinely or naturally given authority of some human beings over others. Only a small minority of postseventeenth-century thinkers have entertained the possibility, perhaps suggested by this postulate, that no form of rule can be justified, but the shift in question altered the political theory agenda. Issues concerning consent, individual liberties and rights, various forms of equality as integral to justice, democratic and other controls on the authority and power of government  none of which were among the first concerns of ancient or medieval political thinkers  moved to the center of political theory. Recurrent tendencies and tensions in political theory may also be discerned along dimensions that cross-cut historical divisions. In its most celebrated representations, political theory is integral to philosophy. Systematic thinkers such as Plato and Aristotle, Augustine and Aquinas, Hobbes and Hegel, present their political thoughts as supporting and supported by their ethics and theology, metaphysics and epistemology. Political argumentation must satisfy the same criteria of logic, truth, and justification as any other; a political doctrine must be grounded in the nature of reality. Other political theorists align themselves with empirical science rather than philosophy. Often focusing on questions of power, they aim to give accurate accounts and factually grounded assessments of government and politics in particular times and places. Books IVVI of Aristotle’s Politics inaugurate this conception of political theory; it is represented by Montesquieu, Marx, and much of utilitarianism, and it is the numerically predominant form of academic political theorizing in the twentieth century. Yet others, e.g., Socrates, Machiavelli, Rousseau, and twentieth-century thinkers such as Rawls, mix the previously mentioned modes but understand themselves as primarily pursuing the practical objective of improving their owpolitical societies.

pro-epi distinction, the: polysyllogism: a series of syllogisms connected by the fact that the conclusion of one syllogism becomes a premise of another. The syllogism whose conclusion is used as a premise in another syllogism within the chain is called the pro-syllogism; the syllogism is which the conclusion of another syllogism within the chain is used as a premise is called the epi-syllogism. To illustrate, take the standard form of the simplest polysyllogism: “All  B is A,”All C is B, “All C is A,” “All C is A,” “ All D is C,” “All D is A. The first member of this polysyllogism is the pro-syllogism, since its conclusion occurs as a premise in the epi-syllogism. Grice: “Part of the charm of my conversations with Strawson was that they were polysyllogistical, my episyllogism invariably following his prosyllogism.””Part of the charm of my conversations with Strawson was that they were polysyllogistical, my episyllogism explicating at what his prosyllogism merely hinted.” Refs.: Grice, “Robbing peter to pay paul.”

pomponazzi: important Italian philosopher. an Aristotelian who taught at the universities of Padua and Bologna. In De incantationibus “On Incantations,” 1556, he regards the world as a system of natural causes that can explain apparently miraculous phenomena. Human beings are subject to the natural order of the world, yet divine predestination and human freedom are compatible De fato, “On Fate,” 1567. Furthermore, he distinguishes between what is proved by natural reason and what is accepted by faith, and claims that, since there are arguments for and against the immortality of the human individual soul, this belief is to be accepted solely on the basis of faith De immortalitate animae, “On the Immortality of the Soul,” He defended his view of immortality in the Apologia 1518 and in the Defensorium 1519. These three works were reprinted as Tractatus acutissimi 1525. Pomponazzi’s work was influential until the seventeenth century, when Aristotelianism ceased to be the main philosophy taught at the universities. The eighteenth-century freethinkers showed new interest in his distinction between natural reason and faith. P.Gar. pons asinorum Latin, ‘asses’ bridge’, a methodological device based upon Aristotle’s description of the ways in which one finds a suitable middle term to demonstrate categorical propositions. Thus, to prove the universal affirmative, one should consider the characters that entail the predicate P and the characters entailed by the subject S. If we find in the two groups of characters a common member, we can use it as a middle term in the syllogistic proof of say ‘All S are P’. Take ‘All men are mortal’ as the contemplated conclusion. We find that ‘organism’ is among the characters entailing the predicate ‘mortal’ and is also found in the group of characters entailed by the subject ‘men’, and thus it may be used in a syllogistic proof of ‘All men are mortal’. To prove negative propositions we must, in addition, consider characters incompatible with the predicate, or incompatible with the subject. Finally, proofs of particular propositions require considering characters that entail the subject. Pietro Pomponazzi Da Wikipedia, l'enciclopedia libera. Jump to navigationJump to search  Pietro Pomponazzi Pietro Pomponazzi, noto anche col soprannome di Peretto Mantovano (Mantova, 16 settembre 1462 – Bologna, 18 maggio 1525), è stato un filosofo e umanista italiano.   Indice 1La vita e l'opera 2Il De immortalitate animae 3La critica dei miracoli 4Il destino dell'uomo 5Conclusioni 6Note 7Bibliografia 8Altri progetti 9Collegamenti esterni La vita e l'opera Di famiglia agiata, nasce a Mantova nel 1462. A ventidue anni si iscrive (1484) all'Università di Padova, dove frequenta le lezioni di metafisica del domenicano Francesco Securo da Nardò, le lezioni di medicina di Pietro Riccobonella e quelle di filosofia naturale di Pietro Trapolino, laureandosi come Magister artium nel 1487. Dal 1488 al 1496 è professore di filosofia nello stesso ateneo e ottiene la cattedra di filosofia naturale dopo la morte del suo maestro Nicoletto Vernia (1420-1499), massimo esponente dell'averroismo locale, di spirito laico e spregiudicato sino alla miscredenza.  A Padova pubblica il trattato De maximo et minimo, in polemica con le teorie di Guglielmo Heytesbury. Passa poi a Carpi (nel 1496) per insegnare logica alla corte di Alberto III Pio, principe di Carpi, seguendolo nel 1498 nel suo esilio a Ferrara e restandovi fino al 1499. Nel frattempo, nel 1497, sposa a Mantova Cornelia Dondi, dalla quale ha due figlie.  Morto Vernia, e succeduto a lui nel 1499, il Pomponazzi rimane poi vedovo nel 1507 e si risposa con Ludovica di Montagnana. Chiude lo studio di Padova nel 1509 e si trasferisce a Ferrara dove redige un commento al De anima aristotelico. Questo avviene in seguito all'occupazione di Padova nel giugno 1509 da parte della Lega di Cambrai nella guerra con la Repubblica veneziana. Quando Venezia rioccupa la città il mese dopo, le lezioni universitarie vengono sospese ed egli, con altri insegnanti, lascia la città trasferendosi, come si è visto, a Ferrara su invito di Alfonso I d'Este per insegnare nella locale università. Chiusa anche questa nel 1510, si trasferisce fino al 1511 a Mantova e dal 1512 all'università di Bologna. Nuovamente vedovo, si risposa con Adriana della Scrofa.  A Bologna scrive le opere maggiori, il Tractatus de immortalitate animae, il De fato e il De incantationibus, oltre a commenti delle opere di Aristotele, conservati grazie agli appunti dei suoi studenti.  Il Tractatus de immortalitate animae, del 1516, in cui sostiene che l'immortalità dell'anima non può essere dimostrata razionalmente, fece scandalo: attaccato da più parti, il libro è pubblicamente bruciato a Venezia. Denunciato dall'agostiniano Ambrogio Fiandino per eresia, la difesa del cardinale Pietro Bembo gli permette di evitare terribili conseguenze ma nel 1518 è condannato da papa Leone X a ritrattare le sue tesi. Pomponazzi non ritratta ma si difende con la sua Apologia del 1518 e con il Defensorium adversus Augustinum Niphum del 1519, una risposta al De immortalitate animae libellus di Agostino Nifo, in cui sostiene la distinzione tra verità di fede e verità di ragione, idea ripresa dal filosofo Roberto Ardigò.  Queste controversie gli impediscono di pubblicare due opere che aveva completato nel 1520: il De naturalium effectuum causis sive de incantationibus e i Libri quinque de fato, de libero arbitrio et de praedestinatione, pubblicati postumi rispettivamente nel 1556 e 1557, con alcune modifiche, a Basilea, da Guglielmo Grataroli. Evita ogni problema teologico pubblicando nel 1521 il De nutritione et augmentatione, il De partibus animalium nel 1521 e il De sensu nel 1524.  Malato di calcoli renali, stende il proprio testamento nel 1524 e muore l'anno dopo. Secondo i suoi allievi Antonio Brocardo ed Ercole Strozzi (1473-1508) egli si sarebbe suicidato.  Il De immortalitate animae  Aristotele nella Scuola di Atene di Raffaello Per Aristotele l'anima è l'atto (entelechia) primo di un corpo che ha la vita in potenza, è la sostanza che realizza le funzioni vitali del corpo. Tre sono le funzioni dell'anima: la funzione vegetativa per la quale gli esseri vegetali, animali e umani si nutrono e si riproducono; la funzione sensitiva per la quale gli esseri animali e umani hanno sensazioni e immagini; la funzione intellettiva, per la quale gli esseri umani comprendono.  L'intelletto è la capacità di giudicare le immagini fornite dai sensi. L'atto dell'intendere si identifica con l'oggetto intelligibile, cioè con la sostanza dell'oggetto, ossia con la verità.  Aristotele distingue l'intelletto potenziale o possibile o passivo, che è la capacità umana di intendere, dall'intelletto attuale o attivo o agente, che è la luce intellettuale. Quest'ultimo contiene in atto tutti gli intelligibili, e agisce sull'intelletto potenziale come - l'esempio è di Aristotele - la luce mostra, mette in atto i colori che al buio non sono visibili ma pure esistono e dunque sono in potenza: l'intelletto agente mette in atto le verità che nell'intelletto potenziale sono soltanto in potenza. L'intelletto agente è separato, non composto, impassibile, per sua essenza atto…separato, esso è solo quel che è realmente, e questo solo è immortale ed eterno.  Che ne è dunque dell'anima? Nella Metafisica Aristotele dice solo che "Bisogna esaminare se la forma esista anche dopo la dissoluzione del composto; per alcune cose nulla lo impedisce, come, ad esempio nel caso dell'anima, ma non dell'anima nella sua interezza, bensì dell'intelletto, poiché è forse impossibile l'esistenza separata dell'anima intera".[1]  L'aristotelismo a Padova si era diviso in due correnti fondamentali, gli averroisti e gli alessandrini, seguaci questi delle interpretazioni aristoteliche di Alessandro di Afrodisia.  Averroè, secondo una concezione influenzata dal platonismo, sosteneva l'unicità e la trascendenza non solo dell'intelletto agente, ma anche dell'intelletto potenziale, che per lui non appartiene ai singoli uomini ma è unico e comune all'intera specie umana. .  La dottrina di Alessandro mantiene l'unicità dell'intelletto agente, che egli fa coincidere con Dio, ma attribuisce a ciascun uomo un intelletto potenziale individuale, mortale insieme con il corpo.   Tommaso d'Aquino ritratto dal Beato Angelico Infine, va ricordato che per Tommaso d'Aquino nell'uomo è presente un'unica anima per sua natura (simpliciter) immortale, ma per un certo aspetto (secundum quid) mortale, in quanto anche legata alle funzioni più materiali dell'essere umano.  Il Trattato dell'immortalità dell'anima, terminato il 24 settembre 1516 ed edito a Bologna il 6 novembre 1516, trae spunto da una discussione con il domenicano Girolamo Raguseo il quale, avendo il Pomponazzi sostenuto che la teoria di Tommaso sull'anima non si accorda con quella aristotelica, lo aveva pregato di provare le sue affermazioni mediante prove puramente razionali.  "Fecero bene gli antichi a porre l'uomo tra le cose eterne e quelle temporali, cosicché egli, né puramente eterno né semplicemente temporale, partecipa delle due nature e stando a metà fra loro, può vivere quella che vuole. Così, alcuni uomini sembrano dei perché, dominando il proprio essere vegetativo e sensitivo, sono quasi completamente razionali. Altri, sommersi nei sensi, sembrano bestie. Altri ancora, uomini nel vero senso della parola, vivono mediamente secondo la virtù, senza concedersi completamente né all'intelletto e né ai piaceri del corpo."[2]  L'uomo dunque, "è di natura non semplice ma molteplice, non determinata ma bifronte (ancipitis), media fra il mortale e l'immortale"ref>Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo I, 5. e questa medietà non è il provvisorio incontro di due nature, una corporea e l'altra spirituale, che si divideranno con la morte, ma è la dimostrazione della reale unità dell'uomo: "La natura procede per gradi: i vegetali hanno un poco di anima, gli animali hanno i sensi e una certa immaginazione…alcuni animali arrivano a costruirsi case e a organizzarsi civilmente tanto che molti uomini sembrano avere un'intelligenza molto inferiore alla loro…vi sono animali intermedi fra la pianta e la bestia, come la spugna…della scimmia non sai se sia uomo o bruto, analogamente l'anima intellettiva è media fra il temporale e l'eterno."[3]  Polemizza con Averroè che ha scisso dalla naturale unità umana il principio razionale da quello sensitivo e con Tommaso d'Aquino, rilevando che l'anima, essendo unica, non può avere due modi di intendere, uno dipendente e un altro indipendente dalle funzioni del corpo; la dipendenza dell'intelligenza dalla fantasia, che dipende a sua volta dai sensi, lega l'anima indissolubilmente al corpo e ne fa seguire lo stesso destino di morte. È capovolta la tesi fondamentale di Tommaso: per Pomponazzi l'anima è per sé mortale e secundum quid, in un certo senso, immortale, e non il contrario, perché "nobilissima fra le cose materiali e al confine con le immateriali, profuma di immortalità ma non in senso assoluto" (aliquid immortalitatis odorat, sed non simpliciter).[4]E ricorda che per Aristotele l'anima non è creata da Dio, "Un uomo infatti è generato da un uomo e anche dal sole".[5]  Riguardo al problema del rapporto fra ragione e fede, per Pomponazzi solo la fede, non le ragioni naturali, può affermare l'immortalità dell'anima e "coloro che camminano per le vie dei credenti sono fermi e saldi",[6] mentre per quanto attiene i problemi etici che la mortalità dell'anima potrebbe suscitare, afferma che per comportarsi virtuosamente non è affatto necessario credere all'immortalità dell'anima e alle ricompense ultraterrene, perché la virtù è premio a sé stessa e chi afferma che l'anima è mortale salva il principio della virtù meglio di chi la considera immortale, perché la speranza di un premio e il terrore della pena provoca comportamenti servili contrari alla virtù.  Il Tractatus provocò clamore e polemiche alle quale rispose nel 1518, ribadendo le sue tesi con l'Apologia, dove nel primo libro risponde alle critiche amichevoli del suo allievo e futuro cardinale Gaspare Contarini e negli altri due al domenicano Vincenzo Colzade e all'agostiniano Ambrogio Fiandino. Nel 1519 replica con il Defensorium adversus Agostinum Niphum alle critiche di Agostino Nifo, professore di filosofia nell'università di Padova. La critica dei miracoli Nel 1520 il medico mantovano Ludovico Panizza avrebbe chiesto a Pomponazzi se possono esserci cause soprannaturali di eventi naturali, in contrasto con le affermazioni di Aristotele, e se si debba ammettere l'esistenza di demoni, come sostiene la Chiesa, anche per spiegare molti fenomeni che si sono verificati.  Per Pomponazzi "dobbiamo spiegare questi fenomeni con cause naturali, senza ricorrere ai demoni…è ridicolo lasciare l'evidenza per cercare quello che non è né evidente né credibile". D'altra parte, poiché l'intelletto percepisce dati sensibili, un puro spirito non potrebbe esercitare un'azione qualunque su qualcosa di materiale: gli spiriti non possono entrare in contatto con il nostro mondo; "in realtà vi sono uomini che, pur agendo per mezzo della scienza, hanno prodotto effetti che, mal compresi, li hanno fatti ritenere opera di santi o di maghi, com'è successo con Pietro d'Abano o con Cecco d'Ascoli…altri, ritenuti santi dal volgo che pensava avessero rapporti con gli angeli…erano magari dei mascalzoni…io credo che facessero tutto questo per ingannare il prossimo".  Ma, a parte casi di incomprensione o di malafede, è possibile che fenomeni mirabolanti abbiano la loro causa nell'influsso degli astri: "È assurdo che i corpi celesti, che reggono tutto l'universo…non possano produrre effetti che di per sé sono nulla considerando l'insieme dell'universo". Cause naturali, comunque, secondo la scienza del tempo: il determinismo astrologico governa anche le religioni: "al tempo degli idoli non c'era maggior vergogna della croce, nell'età successiva non c'è nulla di più venerato...ora si curano i languori con un segno di croce nel nome di Gesù, mentre un tempo ciò non accadeva perché non era giunta la Sua ora".  Ogni religione ha i suoi miracoli "quali quelli che si leggono e si ricordano nella legge di Cristo ed è logico, perché non ci possono essere profonde trasformazioni senza grandi miracoli. Ma non sono miracoli perché contrari all'ordine dei corpi celesti ma perché sono inconsueti e rarissimi".  Nessun fenomeno ha dunque cause non naturali: l'astrologo che abbia colto la natura delle forze celesti, può spiegare tanto le cause di fenomeni che sembrano soprannaturali che realizzare opere straordinarie che il popolino considererà miracolose solo perché incapace di individuarne la causa. L'ignoranza del volgo è del resto sfruttata da politici e da sacerdoti per tenerlo in soggezione, presentandosi ad esso come personaggi straordinari o addirittura inviati da Dio stesso.  Inoltre Pomponazzi sostiene la sua tesi conducendo un discorso di questo tipo:"se Dio ha creato l'universo ponendo su di esso leggi fisiche precise, sarebbe paradossale che egli stesso agisse contro queste leggi utilizzando eventi sovrannaturali come i miracoli". Per Pomponazzi appunto l'universo è controllato e determinato dall'agire degli astri e Dio agisce indirettamente muovendo questi ultimi; Pomponazzi sviluppa quindi una concezione dell'universo deterministica.  Il destino dell'uomo Se tali sono le forze che governano il mondo, se anche i fenomeni soprannaturali hanno una spiegazione nell'esistenza di forze naturali così potenti, esiste ancora una libertà nelle scelte individuali dell'uomo? In Dio, conoscenza e causa delle cose coincidono e dunque egli è veramente libero; l'uomo si esprime invece in un mondo dove tutto è già determinato. Rifiutato il contingentismo di Alessandro di Afrodisia, che salva la libertà umana criticando gli stoici per i quali non esiste né contingenza né libertà umana, Pomponazzi è costretto dalla sua concezione strettamente deterministica, ove tutto è regolato da forze naturali superiori all'uomo, a propendere per l'impossibilità del libero arbitrio:"...l'argomento è per me difficilissimo. Gli stoici sfuggono facilmente alle difficoltà facendo dipendere da Dio l'atto di volontà. Per questo l'opinione stoica appare molto probabile".  Nel cristianesimo c'è maggiore difficoltà a risolvere il problema del libero arbitrio e della predestinazione: "Se Dio odia ab aeterno i peccatori e li condanna, è impossibile che non li odi e non li condanni; e questi, così odiati e reietti, è impossibile che non pecchino e non si perdano. Che rimane, allora, se non una somma crudeltà e ingiustizia divina, e odio e bestemmia contro Dio? E questa è una posizione molto peggiore di quella stoica. Gli stoici dicono infatti che Dio si comporta così perché la necessità e la natura lo impongono. Secondo il cristianesimo il fato dipende invece dalla cattiveria di Dio, che potrebbe fare diversamente ma non vuole, mentre secondo gli stoici Dio fa così perché non può fare altrimenti".  Conclusioni  Lo scrittore Matteo Bandello Chiamato anche Peretto per la piccola statura, secondo Matteo Bandello (Novelle, III, 38) Pietro Pomponazzi "era un omicciolo molto piccolo, con un viso che nel vero aveva più del giudeo che del cristiano e vestiva anco ad una certa foggia che teneva più del rabbi che del filosofo, e andava sempre raso e toso; parlava anche in certo modo che parea un giudeo tedesco che volesse imparar a parlar italiano". Ma lo storico Paolo Giovio dirà che egli "esponeva Aristotele e Averroè con voce dolce e limpidissima; il suo discorso era preciso e pacato nella trattazione, mobile e concitato nella polemica; quando poi giungeva a definire e a trarre le conclusioni, era così grave e posato che gli studenti dai loro posti potevano annotarsi le spiegazioni".  Per nulla tenero con gli uomini di chiesa, "isti fratres truffaldini, domenichini, franceschini, vel diabolini" riassumeva il suo spirito ironico e motteggiante consigliando "alla filosofia credete fin dove vi detta la ragione, alla teologia credete quel che vogliono i teologi e i prelati con tutta la chiesa romana, perché altrimenti farete la fine delle castagne" ma fu serio e senza compromessi nelle sue convinzioni scrivendo nel De fato che "Prometeo è il filosofo che, nello sforzo di scoprire i segreti divini, è continuamente tormentato da pensieri affannosi, non ha sete, non ha fame, non dorme, non mangia, non spurga, deriso, dileggiato, insultato, perseguitato dagli inquisitori, ludibrio del volgo. Questo è il guadagno dei filosofi, questa la loro ricompensa". Epperò i filosofi sono per lui "come Dei terreni, tanto lontani dagli altri come gli uomini veri lo sono dalle figure dipinte" e lui sarebbe pronto, per amore della verità, anche a "ritrattare quel che ho detto. Chi dice che polemizzo per il gusto di contrastare, mente. In filosofia, chi vuol trovare la verità, dev'essere eretico".  Note ^ Aristotele, Metafisica, XII, 1070a, 2-27. ^ Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo I, 3-4. ^ Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo IX. ^ Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo IX, 20. ^ Aristotele, Fisica, II, 194b 11-15; Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo VII. ^ Pietro Pomponazzi, Trattato sull'immortalità dell'anima, Capitolo XV.

porfirio: Grice preferred to read the Latin version by Boezio – “Perhaps not literal, but implicatural.” -- Grecian Neoplatonist philosopher, second to Plotinus in influence. He was born in Tyre, and is thus sometimes called Porphyry the Phoenician. As a young man he went to Athens, where he absorbed the Platonism of Cassius Longinus, who had in turn been influenced by Ammonius Saccas in Alexandria. Porphyry went to Rome in 263, where he became a disciple of Plotinus, who had also been influenced by Ammonius. Porphyry lived in Rome until 269, when, urged by Plotinus to pons asinorum Porphyry 722    722 travel as a cure for severe depression, he traveled to Sicily. He remained there for several years before returning to Rome to take over Plotinus’s school. He apparently died in Rome. Porphyry is not noted for original thought. He seems to have dedicated himself to explicating Aristotle’s logic and defending Plotinus’s version of Neoplatonism. During his years in Sicily, Porphyry wrote his two most famous works, the lengthy Against the Christians, of which only fragments survive, and the Isagoge, or “Introduction.” The Isagoge, which purports to give an elementary exposition of the concepts necessary to understand Aristotle’s Categories, was tr. into Latin by Boethius and routinely published in the Middle Ages with Latin editions of Aristotle’s Organon, or logical treatises. Its inclusion in that format arguably precipitated the discussion of the so-called problem of universals in the twelfth century. During his later years in Rome, Porphyry collected Plotinus’s writings, editing and organizing them into a scheme of his own  not Plotinus’s  design, six groups of nine treatises, thus called the Enneads. Porphyry prefaced his edition with an informative biography of Plotinus, written shortly before Porphyry’s own death. 

positive and negative freedom, respectively, the area within which the individual is self-determining and the area within which the individual is left free from interference by others. More specifically, one is free in the positive sense to the extent that one has control over one’s life, or rules oneself. In this sense the term is very close to that of ‘autonomy’. The forces that can prevent this self-determination are usually thought of as internal, as desires or passions. This conception of freedom can be said to have originated with Plato, according to whom a person is free when the parts of the soul are rightly related to each other, i.e. the rational part of the soul rules the other parts. Other advocates of positive freedom include Spinoza, Rousseau, Kant, and Hegel. One is free in the negative sense if one is not prevented from doing something by another person. One is prevented from doing something if another person makes it impossible for one to do something or uses coercion to prevent one from doing something. Hence persons are free in the negative sense if they are not made unfree in the negative sense. The term ‘negative liberty’ was coined by Bentham to mean the absence of coercion. Advocates of negative freedom include Hobbes, Locke, and Hume.  

Positivism: one of the twelve labours by Grice. Each has an entry in this alphabetum, even if conceptually, what they deal with is treated in other entries too.

posse --- 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.” 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. 

PARS-TOTUM -- partiale-impartialis – impartiality: Grice found this amusing. “Surely conversational maxims, constituting the conversational immanuel, are impartial – i.e. they are not part of any other part!” – “However, it’s only because they can be partial that’s the only way they can have a bite on us!” -- a state or disposition achieved to the degree that one’s actions or attitudes are not influenced in a relevant respect by which members of a relevant group are benefited or harmed by one’s actions or by the object of one’s attitudes. For example, a basketball referee and that referee’s calls are impartial when the referee’s applications of the rules are not affected by whether the calls help one team or the other. A fan’s approval of a call lacks impartiality if that attitude results from the fan’s preference for one team over the other. Impartiality in this general sense does not exclude arbitrariness or guarantee fairness; nor does it require neutrality among values, for a judge can be impartial between parties while favoring liberty and equality for all. Different situations might call for impartiality in different respects toward different groups, so disagreements arise, for example, about when morality requires or allows partiality toward friends or family or country. Moral philosophers have proposed various tests of the kind of impartiality required by morality, including role reversibility (Kurt Baier), universalizability (Hare), a veil of ignorance (Rawls), and a restriction to beliefs shared by all rational people (Bernard Gert).


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. 

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.

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. 

Praedicatum –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. Top.140b37; “τὸ κοινῇ -ούμενον ἐπὶ πᾶσιν” Id.SE179a8: abs., τὸ κατηγορούμενον the predicate, opp. τὸ ὑποκείμενον (the subject), Id.Cat.1b11, cf.Metaph.1043a6, al.; κατηγορεῖν καὶ -εῖσθαι to be subject and predicate, Id.APr.47b1. BANC.  Praedicatum -- 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.  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. 

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.  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: Grice: “I dislike the expression Old World if it means Eurasia – if it means just Europe, that’s OK.” -- 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. 

prae-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. 

prædicatum: Grice on the praedicatum/impraedicatum distinction – an impredicative definition is the definition of a concept in terms of the totality to which it belongs. Whitehead and Russell, in their “Principia Mathematica” introduce ‘im-predicative’ (earlier, ‘non-predicative,’ which Grice prefers) prohibiting an impredicative definition from conceptual analysis, on the grounds that an impredicative definition entails (to use Moore’s jargon) a paradox – which Grice loves. An impredicative definition of the set R of all sets that are not members of themselves leads to the self-contradictory conclusion that R is a member of itself if and only if it is not a member of itself. In Grice’s rewrite: “Austin’s paradoxical dream was to create a ‘class’ each of whose member was such that his class had no other member.” To avoid an antinomy of this kind in the formalization of logic, Whitehead and Russell first implement in their ramified type theory the vicious circle principle, that no whole (totum) may contain parts (pars) that are definable only in terms of that whole (totum). The limitation of ramified type theory is that without use of an impredicative definition it is impossible to quantify over every item, but only over every item of a certain order or type. Without being able to quantify over every item generally, many of the most important definitions and theorems of classical philosophy cannot be formulated. Whitehead and Russell for this reason later abandoned ramified in favour of simple type theory, which avoids a logical paradox without outlawing an impredicative definition by forbidding the predication of terms of any type (object, property and relation, higher-order propertiy and relations of properties and relations, etc.) to terms of the same type.
correctum: there’s‘corrigibility’ (=  correctum) and ‘incorrigibility’ – “The implicaturum is that something is incorrigibile it cannot be corrected – but Chisholm never explies ‘by whom’”! (Grice uses ‘exply’ as opposite of ‘imply’).  Who is corrigible? The emissor. “I am sorry I have to tell you you are wrong.” On WoW: 142, Grice refers to the ‘authority’ of the utterer as a ‘rational being’ to DEEM that an M-intention is an antecedent condition for his act of meaning. Grice uses ‘privilege’ as synonym for ‘authority’ here. But not in the phrase ‘privileged access.’ His point is not so much about the TRUTH (which ‘incorrigibility’ suggests), but about the DEEMING. It is part of the authority or privilege of the utterer as rational to provide an ACCEPTABLE assignment of an M-intention behind his utterance.


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.

Prae-latum -- 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.


Prae--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.

Prae-scriptivism, 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. 

prae-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. 

praesupposition, 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.

Prae-theoretical, 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. 

praescriptum: 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.

Viene cresciuto dalla nonna materna in lingua francese, e attraverso di lei inizia a conoscere la cultura e la lingua greca; come vedremo, entrambe queste circostanze avranno un grande rilievo nella vita di Preve. Personalmente non è credente, pur riconoscendo l'importanza del fenomeno religioso.[2] Studia a Torino, dove conseguirà la maturità classica nel 1962; durante i mesi estivi lavora in campagna nel Regno Unito. Dietro pressioni del padre, nel 1962 si iscrive alla facoltà di giurisprudenza dell'Università di Torino. Verificando il suo totale disinteresse per gli studi giuridici, nel 1963 decide di passare alla facoltà di Scienze politiche, che però non frequenterà mai; nel giugno 1967 ne conseguirà ugualmente la laurea, discutendo con il professor Alessandro Galante Garrone una tesi sui "Temi delle elezioni politiche italiane del 18 aprile 1948".  Sempre nel 1963 vince per concorso una borsa di studio all'Università di Parigi, dove si reca con il proposito di condurre studi filosofici; qui seguirà i corsi su Hegel tenuti da Jean Hyppolite, frequenterà i seminari di Louis Althusser e Jean-Paul Sartre, e sotto la guida di Roger Garaudy e di Gilbert Mury, si avvicinerà a Karl Marx. A Parigi segue soprattutto corsi di filosofia greca classica e di germanistica, e nel 1964 grazie ad una borsa di studio si reca per un semestre invernale alla Freie Universität di Berlino. Nel 1965 passa dal dipartimento di germanistica a quello di neoellenistica, e vince una borsa di studio per recarsi ad Atene; all'Università di Atene studia greco classico con Panagis Lekatsas e storia contemporanea con Nikos Psyroukhis, che esercitano su di lui un grande ascendente. Qui prepara una tesi di laurea in greco moderno sul tema: "L'illuminismo greco e le sue tendenze radicali e rivoluzionarie. Etnogenesi della nazione greca moderna fra Settecento e Ottocento. Il problema della discontinuità con la grecità classica e con la grecità bizantina”. Poliglotta dagli anni dell'università, e fermo sostenitore della lettura dei testi filosofici nella lingua originale, egli apprenderà inglese, portoghese, francese, tedesco, spagnolo, russo, greco antico e moderno, arabo, ebraico, e latino.  Nel 1967 ritorna a Torino e si sposa l'anno seguente; nello stesso 1968 consegue per concorso l'abilitazione all'insegnamento liceale di lingua e letteratura francese e di storia della filosofia mentre nel 1970 vince il concorso nazionale di ordinariato per l'insegnamento della filosofia e della storia nei licei. Insegnante dal 1967 fino alla pensione del 2002, per due anni (1967-69) insegna francese e inglese, mentre per trentatré anni (1969-2002) è docente di storia e filosofia al V Liceo Scientifico di Torino (oggi Liceo Alessandro Volta). Trascorre gli anni che vanno dal 1967 al 1978 in un'intensa attività politica, aderendo dal 1973 al 1975 al PCI per poi militare in vari gruppi della sinistra extraparlamentare; in questi anni, l'attività filosofica di Preve è incentrata nel tentativo di conciliare esistenzialmente il comunismo, il marxismo e la filosofia.  Nel 1978 Gianfranco La Grassa, Maria Turchetto ed Augusto Illuminati lo invitano a varie collaborazioni; con essi fonderà nel 1982 il CSMS (Centro Studi di Materialismo Storico) di Milano, del quale redigerà inoltre il manifesto programmatico. In questo contesto, e per finanziamento di questo centro, esce il suo primo volume indipendente (cfr. La filosofia imperfetta, Franco Angeli, Milano 1984). Questo testo testimonia la sua adesione di massima alla proposta filosofica dell'Ontologia dell'essere sociale dell'ultimo Lukács[3], ed anche, indirettamente, il suo distacco definitivo dalla scuola di Louis Althusser. Insieme con Franco Volpi, Maria Turchetto, Augusto Illuminati, Fabio Cioffi, Amedeo Vigorelli, ed altri fonda nel 1980 a Milano la rivista di dibattito “Metamorfosi”, che pubblicherà sedici numeri di tipo monografico per tutti gli anni ottanta.  In quasi tutti i fascicoli vi sono suoi contributi, che spaziano da un esame dell'operaismo italiano da Panzieri a Tronti e Negri, all'analisi del marxismo dissidente nei paesi socialisti, alla discussione sulla filosofia di Lukács, alla critica delle ideologie del progresso storico, all'indagine sullo statuto filosofico della critica marxiana dell'economia politica. Nel 1983 contribuisce ad organizzare, insieme con Emilio Agazzi, un congresso internazionale dedicato al centenario della morte di Marx (Milano, dicembre 1983), e vi svolge una relazione sulle categorie modali di necessità e di possibilità in Marx. Da quest'esperienza nasce una rivista chiamata “Marx 101”, che uscirà nei due decenni successivi in due serie di numeri monografici e di cui Preve sarà membro del comitato di redazione. Per tutti gli anni ottanta collabora al mensile teorico “Democrazia Proletaria”, organo dell'omonimo partito (1976-1991)[4], che poi diverrà insieme con i fuoriusciti dal PCI la seconda componente politica e militante del PRC (Partito della Rifondazione Comunista).  Sarà iscritto a DP soltanto per un breve periodo (1988-1991), facendo parte della direzione nazionale; nella battaglia politica fra i sostenitori di una scelta ecologista (Mario Capanna) e neocomunista, Preve sostiene la seconda con una serie di articoli. Nel 1991, quando le componenti di Democrazia Proletaria e dell'Associazione Culturale Marxista confluiscono nel Partito della Rifondazione Comunista, Preve abbandona la militanza politica diretta. Fra il 1989 ed il 1994, con la pubblicazione di otto volumi consecutivi usciti presso l'editore Vangelista di Milano, Preve affronta il suo “ultimo tentativo personale di coerentizzazione di un paradigma filosofico marxista globale”. A partire dalla seconda metà degli anni novanta si verifica infatti una discontinuità nella sua produzione; Preve opta per l'abbandono di ogni “ismo” di riferimento, uscendo del tutto “dalla cosiddetta Sinistra” e dalle sue procedure di “accoglimento e cooptazione”.  Ritenendo che la globalizzazione nata dall'implosione dell'Unione Sovietica non si lasci più “interrogare” attraverso le categorie di Destra e di Sinistra, ma richieda altre categorie interpretative, Preve diviene inoltre un convinto sostenitore della necessità di superare la dicotomia sinistra-destra[5]. Questa posizione, condivisa da alcuni intellettuali e movimenti internazionali, è stata criticata da molti, tra cui lo scrittore Valerio Evangelisti, che ne ha sottolineato l'ambiguità ideologica[6].  Autore e saggista molto prolifico, ha dedicato le sue ultime riflessioni a temi come il comunitarismo[7], la geopolitica[8], l'universalismo[9], la questione nazionale[10], oltre ovviamente ad un'ininterrotta attenzione al rapporto marxismo-filosofia.[11] Muore a Torino il 23 novembre 2013[12][13][14][15] per un male incurabile[16]; il Consiglio Comunale di Torino lo ha omaggiato sottolineando il ruolo di Preve e l'importante stimolo al dibattito culturale e politico da lui sviluppato, rilevante per la crescita politica collettiva in Italia[17]. Pensiero La sua riflessione può essere distinta in due periodi successivi. Nel primo periodo (1975-1991 circa), ha cercato di opporsi alla deriva post-moderna seguita dalla stragrande maggioranza della sinistra italiana (in particolare dagli intellettuali legati al PCI) con un recupero dei punti alti della tradizione marxista indipendente, del tutto estranea alle incorporazioni burocratiche del marxismo come ideologia di legittimazione di partiti e di stati (soprattutto l'ultimo Lukács, l'ultimo Althusser, Ernst Bloch, Adorno). In un secondo periodo, dopo la fine del socialismo reale (che Preve chiama comunismo storico novecentesco 1917-1991), ed in dissenso con tutti i tentativi di sua continuazione/rifondazione puramente politico-organizzativa, ha invece lavorato su di una generale rifondazione antropologica del comunismo, marcando sempre più la discontinuità teorica e politica con i conglomerati identitari della sinistra italiana[18] (Rifondazione Comunista in primis, ma anche la scuola operaista e Toni Negri in particolar modo).  Durante gli anni novanta i suoi interventi sono apparsi sia su riviste legate alla sinistra alternativa (L'Ernesto, Bandiera Rossa) che su riviste come Indipendenza e Koiné, dove Preve ha sostenuto l'esplicito superamento del dualismo Destra/Sinistra[19], approdando a posizioni antitetiche a quelle del filosofo Norberto Bobbio (con cui ebbe uno stretto rapporto per più di vent'anni). Nei primi anni del nuovo millennio ha collaborato con la rivista Comunitarismo, prima, e Comunità e Resistenza, poi. È stato fino alla morte redattore del quadrimestrale Comunismo e Comunità[20]. Al di là delle prese di posizione sulla congiuntura politica, tre cardini del pensiero di Costanzo Preve sono l'interpretazione della storia della filosofia, l'analisi filosofica del capitalismo e la proposta politica per un comunismo comunitario universalistico.  Interpretazione della storia della filosofia Rileggendo l'intera storia della filosofia soprattutto occidentale, Preve utilizza una deduzione sociale delle categorie del pensiero non riduzionistica, che gli permette di discernere la genesi particolare delle idee dalla loro validità universale. Infatti quello di Preve è un orizzonte aperto universalisticamente alla verità, intesa hegelianamente come processo di autocoscienza storica e sintesi di ontologia e assiologia, dell'esperienza umana nella storia. Nella sua proposta di ontologia dell'essere sociale riconosce razionalmente la natura solidale e comunitaria dell'anima umana e l'autonomia conoscitiva della filosofia, contrastando ogni forma di riduzionismo nichilistico, relativistico o partigianamente ideologico. Preve viene definito «strenuo difensore dello statuto veritativo della filosofia da una parte, e [...] deciso oppositore di ogni fraintendimento relativistico dall’altra»[21].  Analisi filosofica del capitalismo Preve intende il capitalismo come totalità economica, politica e culturale da indagare in tutte le sue dimensioni. Propone di suddividerlo filosoficamente e idealisticamente in tre fasi: astratta (XVII-XVIII secolo); dialettica (dal 1789 al 1991) con una protoborghesia illuministica o romantica, una medioborghesia dal 1848 positivistica e poi dal 1914 esistenzialistica, e una tardoborghesia dal 1968 al 1990 sempre più individualistica e libertaria; speculativa (post-borghese e post-proletaria, dal 1991 in poi) in cui il capitale si concretizza come assoluto, espandendosi al di là delle dicotomie precedenti a destra economicamente, al centro politicamente e a sinistra culturalmente.  Politicamente corretto Nell'analisi filosofica del capitalismo, più volte insiste sulla critica al politicamente corretto, dove riprende alcuni dei suoi temi già trattati; il concetto consterebbe dei seguenti punti nella concezione previana (dove è considerato un'arma del capitalismo per attrarre fasce deboli a sé, nonché un'ideologia di fondo dell'occidente imperialista)[22]:  americanismo come collocazione presupposta, anche sotto forma di benevola critica al governo statunitense; "religione olocaustica": Preve non aderisce al negazionismo dell'Olocausto e condanna i genocidi, ma considera la shoah un fatto non "unico", utilizzato dal sionismo per legittimare le azioni di Israele tramite il senso di colpa dell'Europa: «Auschwitz non può e non deve essere dimenticato, perché la memoria dei morti innocenti deve essere riscattata, e questo mondo nella sua interezza appartiene a tre tipi di esseri umani: coloro che sono già vissuti, coloro che sono tuttora in vita, e coloro che devono ancora nascere. Ma Auschwitz non deve diventare un simbolo di legittimazione del sionismo, che agita l'accusa di antisemitismo in tutti coloro che non lo accettano radicalmente, e che non sono disposti a derubricare a semplici errori i suoi veri e propri crimini[23]»  "teologia dei diritti umani", che Preve considera (come altri filosofi marxisti come Slavoj Žižek o Domenico Losurdo, o comunitaristi come Alain de Benoist) solo un grimaldello e un paravento del capitalismo per imporsi ed eliminare, in realtà, i diritti dei popoli e dei lavoratori, attuando il liberismo e l'imperialismo globali; antifascismo in assenza completa di fascismo: l'antifascismo, positivo un tempo, è considerato un fenomeno dannoso e a favore del sistema capitalistico, visto che il fascismo (da lui deprecato soprattutto per la colonizzazione imperialistica dell'Africa e la "mascalzonaggine imperdonabile" dell'invasione della Grecia) è stato ormai sconfitto, volto a creare tensioni tra le diverse forze anti-sistema, e a fungere da nuova ideologia della sinistra postcomunista e post-stalinista (dopo il graduale abbandono del marxismo-leninismo avvenuto secondo Preve a partire dal 1956 per gli effetti della destalinizzazione), che diviene così inutile; falsa dicotomia Sinistra/Destra come "protesi di manipolazione politologica": derivata dal precedente, questa teoria punterebbe a indebolire le critiche anticapitalistiche, impedendo l'unione tra comunisti, comunitaristi e socialisti nazionalitari contro il capitale. Al contempo, anche per le nette e costanti affermazioni contro i tribalismi, i razzismi e i nazionalismi soprattutto coloniali, è da ritenersi estranea al cosiddetto "rossobrunismo" (un termine coniato all'inizio per descrivere i cosiddetti nazionalboscevichi) di cui fu tacciato dal citato Valerio Evangelisti[6], che a suo dire si configurerebbe come una folle somma dei difetti degli estremismi opposti: «L'unione di sostenitori rasati del razzismo biologico con sostenitori barbuti della dittatura del proletariato sarebbe certamente un buon copione di pornografia hard, ma non potrebbe uscire dal piccolo circuito a luci rosse del sottobosco politico.[24]» nismo comunitario La proposta politica di Costanzo Preve va nella direzione di un comunismo comunitario universalistico, da intendersi come correzione democratica e umanistica del comunismo, dal momento che quello storico novecentesco sarebbe stato reo di non aver messo in comune innanzitutto la verità. Quello tratteggiato da Preve è un sistema sociale che costituisce una sintesi di individui liberati e comunità solidali. Non è inteso come inevitabile sbocco storicistico o positivistico di una storia che si svilupperebbe linearmente, né tuttavia in modo aleatorio in senso althusseriano, bensì aristotelicamente in potenza, a partire dalla resistenza alla dissoluzione comunitaria innescata dall'accumulazione individuale di merci. Qui il problema dell'auspicabile democrazia viene impostato su basi antropologiche, scommettendo sulle potenzialità ontologiche della bontà dell'anima umana, potenzialmente politico-comunitaria (zόon politikόn); razionale e valutativa della giusta misura sociale (zόon lόgon échon) e generica, in senso marxiano (Gattungswesen), cioè in grado di costruire diversi modelli di convivenza sociale, compreso quello in cui l'uomo, affermando la priorità etica e comunitaria per contenere i processi economici altrimenti dispiegantisi in modo illimitato e disumano, può realizzare le sue potenzialità ontologiche immanenti, attualmente alienate. La liberazione dell'individuo avverrebbe quindi a partire dal suo radicamento comunitario in cui agisce collettivamente, pur rimanendo l'individuo stesso l'unità minima di resistenza al potere.  Attività politica In gioventù aderì al PCI dal 1973 al 1975, ma presto si allontanò (essendo ostile al compromesso storico tra PCI e DC, promosso da Berlinguer e Moro), entrando poi a far parte della Commissione culturale di Lotta Continua. In seguito si iscrisse a Democrazia Proletaria durante la sua ultima fase (1988-1991)[25] Dopo lo scioglimento di DP, e in seguito alla confluenza di quest'ultima in Rifondazione Comunista, si è sempre più allontanato dall'attività politica in senso stretto[26]. In seguito manifestò critiche verso l'operaismo e il trotskismo che animavano talvolta queste esperienze della post-sinistra extraparlamentare.  Se dal punto di vista teorico si era già distanziato dalla sinistra italiana a seguito della dissoluzione dell'Unione Sovietica e della svolta della Bolognina (1989), il distacco emotivo definitivo dalla "sinistra" avvenne con il bombardamento NATO in Jugoslavia del marzo 1999 durante la guerra del Kosovo, che ricevette il beneplacito del governo italiano guidato da Massimo D'Alema; Preve ha considerato questo fatto come la fine della legalità costituzionale italiana riferendosi alla violazione dell'articolo 11 e un atto di tradimento verso i valori fondanti della Repubblica Italiana.[27] Sul tema scrisse Il bombardamento etico. Saggio sull'interventismo umanitario, l'embargo terapeutico e la menzogna evidente (2000).  Molto clamore ha suscitato (anche tra le file della sinistra alternativa) la sua adesione ad alcune tesi del Campo Antimperialista, nel 2003, per l'esplicito sostegno da questi fornito alla resistenza irachena[28]. È stato uno dei filosofi di riferimento del comunismo comunitario, nonché animatore della rivista Comunismo e Comunità.  Opere La classe operaia non va in paradiso: dal marxismo occidentale all'operaismo italiano, in Alla ricerca della produzione perduta, Bari, Dedalo, 1982.

Prichard: h. a. – H. P. Grice called himself a neo-Prichardian, but then “I used to be a neo-Stoutian before that!” – London-born Welshman and 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 – problem – “Philosophy is about problems” – Grice. 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.

Proprium – From ‘proprium’ you get the abstdract noun, “proprietas” – as in “proprietates terminorum,” each one being a “proprietas”-- 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.

(September 1972): ... vice versa. The proprium is a necessary, but non-essential, property. ... Alan Code pointed this out to me. ' Does Aristotle ...

(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: “The etymology is fascinating – if I knew it.” – Grice – Grice’s protocol. from Medieval Latin protocollum "draft," literally "the first sheet of a volume" (on which contents and errata were written), from Greek prōtokollon "first sheet glued onto a manuscript," from prōtos "first" (see proto-) + kolla "glue. -- 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. 


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.

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. 

Pitagora – or as Strawson would prefer, “Pythagoras.”La scuola pitagorica a Crotone -- Pythagoras, the most famous of the pre-Socratic Grecian philosophers. He emigrated from the island of Samos off Asia Minor to Crotone, in 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.
