propositional opacity,
failure of a clause to express any particular proposition especially due to the
occurrence of pronouns or demonstratives. If having a belief about an
individual involves a relation to a proposition, and if a part of the
proposition is a way of representing the individual, then belief
characterizations that do not indicate the believer’s way of representing the
individual could be called propositionally opaque. They do not show all of the
propositional elements. For example, ‘My son’s clarinet teacher believes that
he should try the bass drum’ would be propositionally opaque because ‘he’ does
not indicate how my son John’s teacher represents John, e.g. as his student, as
my son, as the boy now playing, etc. This characterization of the example is
not appropriate if propositions are as Russell conceived them, sometimes
containing the individuals themselves as constituents, because then the propositional
constituent John has been referred to. Generally, a characterization of a
propositional 754 attitude is
propositionally opaque if the expressions in the embedded clause do not refer
to the propositional constituents. It is propositionally transparent if the
expressions in the embedded clause do so refer. As a rule, referentially opaque
contexts are used in propositionally transparent attributions if the referent
of a term is distinct from the corresponding propositional constituent.
proprietates terminorum
Latin, ‘properties of terms’, in medieval logic from the twelfth century on, a
cluster of semantic properties possessed by categorematic terms. For most
authors, these properties apply only when the terms occur in the context of a
proposition. The list of such properties and the theory governing them vary
from author to author, but always include 1 suppositio. Some authors add 2
appellatio ‘appellating’, ‘naming’, ‘calling’, often not sharply distinguishing
from suppositio, the property whereby a term in a certain proposition names or
is truly predicable of things, or in some authors of presently existing things.
Thus ‘philosophers’ in ‘Some philosophers are wise’ appellates philosophers
alive today. 3 Ampliatio ‘ampliation’, ‘broadening’, whereby a term refers to
past or future or merely possible things. The reference of ‘philosophers’ is
ampliated in ‘Some philosophers were wise’. 4 Restrictio ‘restriction’,
‘narrowing’, whereby the reference of a term is restricted to presently
existing things ‘philosophers’ is so restricted in ‘Some philosophers are
wise’, or otherwise narrowed from its normal range ‘philosophers’ in ‘Some
Grecian philosophers were wise’. 5 Copulatio ‘copulation’, ‘coupling’, which is
the type of reference adjectives have ‘wise’ in ‘Some philosophers are wise’,
or alternatively the semantic function of the copula. Other meanings too are
sometimes given to these terms, depending on the author. Appellatio especially
was given a wide variety of interpretations. In particular, for Buridan and
other fourteenth-century Continental authors, appellatio means ‘connotation’.
Restrictio and copulatio tended to drop out of the literature, or be treated
only perfunctorily, after the thirteenth century.

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.
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 statement, 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 theory, a
theory according to which human cognition involves the deployment of
“categories” organized around stereotypical exemplars. Prototype theory differs
from traditional theories that take the concepts with which we think to be
individuated by means of boundary-specifying necessary and sufficient
conditions. Advocates of prototypes hold that our concept of bird, for
instance, consists in an indefinitely bounded conceptual “space” in which
robins and sparrows are central, and chickens and penguins are peripheral though the category may be differently
organized in different cultures or groups. Rather than being all-ornothing,
category membership is a matter of degree. This conception of categories was
originally inspired by the notion, developed in a different context by Vitters,
of family resemblance. Prototypes were first discussed in detail and given
empirical credibility in the work of Eleanor Rosch see, e.g., “On the Internal
Structure of Perceptual and Semantic Categories,” 3.
Proudhon, Pierre-Joseph
180965, socialist theorist and father of
anarchism. He became well known following the publication of What Is Property?
1840, the work containing his main ideas. He argued that the owner of the means
of production deprives the workers of a part of their labor: “property is
theft.” In order to enable each worker to dispose of his labor, capital and
largescale property must be limited. The need to abolish large-scale private
property surpassed the immediate need for a state as a controlling agent over
chaotic social relationships. To this end he stressed the need for serious
reforms in the exchange system. Since the economy and society largely depended
on the credit system, Proudhon advocated establishing popular banks that would
approve interest-free loans to the poor. Such a mutualism would start the
transformation of the actual into a just and nonexploited society of free
individuals. Without class antagonism and political authorities, such a society
would tend toward an association of communal and industrial collectivities. It
would move toward a flexible world federation based on self-management. The
main task of social science, then, is to make manifest this immanent logic of
social processes. Proudhon’s ideas influenced anarchists, populists Bakunin,
Herzen, and syndicalists Jaurès. His conception of self-management was an
important inspiration for the later concept of soviets councils. He criticized
the inequalities of the contemporary society from the viewpoint of small
producers and peasants. Although eclectic and theoretically rather naive, his
work attracted the serious attention of his contemporaries and led to a strong
attack by Marx in The Holy Family and The Poverty of Philosophy.
prudens: practical reason: In “Epilogue” Grice states that the principle of
conversational rationality is a sub-principle of the principle of rationality,
simpliciter, which is not involved with ‘communication’ per se. This is an
application of Occam’s razor: Rationalities are not to be multiplied beyond
necessity.” This motto underlies his aequi-vocality thesis: one reason:
desiderative side, judicative side. Literally, ‘practical reason’ is the
buletic part of the soul (psyche) that deals with praxis, where the weighing is
central. We dont need means-end rationality, we need value-oriented
rationality. We dont need the rationality of the means – this is obvious --. We
want the rationality of the ends. The end may justify the means. But Grice is
looking for what justifies the end. The topic of freedom fascinated Grice,
because it merged the practical with the theoretical. Grice sees the
conception of freedom as crucial in his elucidation of a rational being. Conditions
of freedom are necessary for the very idea, as Kant was well aware. A thief who
is forced to steal is just a thief. Grice would engage in a bit of language
botany, when exploring the ways the adjective free is used, freely, in ordinary
language: free fall, alcohol-free, sugar-free, and his favourite: implicaturum-free.
Grices more systematic reflections deal with Pology, or creature construction.
A vegetals, for example is less free than an animal, but more free than a
stone! And Humans are more free than non-human. Grice wants to deal with some
of the paradoxes identified by Kant about freedom, and he succeeds in solving
some of them. There is a section on freedom in Action and events for PPQ where he expands on eleutheria and notes the
idiocy of a phrase like free fall. Grice was irritated by the fact that his
friend Hart wrote an essay on liberty and not on freedom, cf. praxis. Refs.:
essays on ‘practical reason,’ and “Aspects,” in BANC.
ψ-transmissum. Or ‘soul-to-soul transfer’ “Before we study
‘psi’-transmission we should study ‘transmission’ simpliciter. It is cognate
with ‘emission.’ So the emissor is a transmissor. And the emissee is a
transemissee. Grice would never have
thougth that he had to lecture on what conversation is all about! He would
never have lectured on this to his tutees at St. John’s – but at Brighton is
all different. So, to communicate, for an emissor is to intend his recipient to
be in a state with content “p.” The modality of the ‘state’ – desiderative or
creditative – is not important. In a one-off predicament, the emissor draws a
skull to indicate that there is danger. So his belief and desire were
successfully transmitted. A good way to formulate the point of communication.
Note that Grice is never sure about analsans and analysandum: Emissor
communicates THAT P iff Emissor M-INTENDS THAT addressee is to psi- that P.
Which seems otiose. “It is raining” can be INFORMATIVE, but it is surely
INDICATIVE first. So it’s moke like the emissor intends his addressee to
believe that he, the utterer believes that p (the belief itself NOT being part
of what is meant, of course). So, there is psi-transmission not necessarily
when the utterer convinces his addressee, but just when he gets his addressee
to BELIEF that he, the utterer, psi-s that p. So the psi HAS BEEN TRANSMITTED.
Surely when the Beatles say “HELP” they don’t expect that their addressee will
need help. They intend their addressee to HELP them! Used by Grice in WoW: 287,

pseudo-hallucination, a
non-deceptive hallucination. An ordinary hallucination might be thought to
comprise two components: i a sensory component, whereby one experiences an
image or sensory episode similar in many respects to a veridical perceiving
except in being non-veridical; and ii a cognitive component, whereby one takes
or is disposed to take the image or sensory episode to be veridical. A
pseudohallucination resembles a hallucination, but lacks this second component.
In experiencing a pseudohallucination, one appreciates that one is not
perceiving veridically. The source of the term seems to be the painter Wassily
Kandinsky, who employed it in 5 to characterize a series of apparently
drug-induced images experienced and pondered by a friend who recognized them,
at the very time they were occurring, not to be veridical. Kandinsky’s account
is discussed by Jaspers in his General Psychopathology, 6, and thereby entered
the clinical lore. Pseudohallucinations may be brought on by the sorts of
pathological condition that give rise to hallucinations, or by simple fatigue,
emotional adversity, or loneliness. Thus, a driver, late at night, may react to
non-existent objects or figures on the road, and immediately recognize his
error.
psycholinguistics, an
interdisciplinary research area that uses theoretical descriptions of language
taken from linguistics to investigate psychological processes underlying
language production, perception, and learning. There is considerable
disagreement as to the appropriate characterization of the field and the major
problems. Philosophers discussed many of the problems now studied in
psycholinguistics before either psychology or linguistics were spawned, but the
self-consciously interdisciplinary field combining psychology and linguistics
emerged not long after the birth of the two disciplines. Meringer used the
adjective ‘psycholingisch-linguistische’ in an 5 book. Various national
traditions of psycholinguistics continued at a steady but fairly low level of
activity through the 0s and declined somewhat during the 0s and 0s because of
the antimentalist attitudes in both linguistics and psychology. Psycholinguistic
researchers in the USSR, mostly inspired by L. S. Vygotsky Thought and
Language, 4, were more active during this period in spite of official
suppression. Numerous quasi-independent sources contributed to the rebirth of
psycholinguistics in the 0s; the most significant was a seminar held at a during the summer of 3 that led to the
publication of Psycholinguistics: A Survey of Theory and Research Problems 4,
edited by C. E. Osgood and T. A. Sebeok
a truly interdisciplinary book jointly written by more than a dozen
authors. The contributors attempted to analyze and reconcile three disparate
approaches: learning theory from psychology, descriptive linguistics, and
information theory which came mainly from engineering. The book had a wide
impact and led to many further investigations, but the nature of the field
changed rapidly soon after its publication with the Chomskyan revolution in
linguistics and the cognitive turn in psychology. The two were not unrelated:
Chomsky’s positive contribution, Syntactic Structures, was less broadly
influential than his negative review Language, 9 of B. F. Skinner’s Verbal
Behavior. Against the empiricist-behaviorist view of language understanding and
production, in which language is merely the exhibition of a more complex form
of behavior, Chomsky argued the avowedly rationalist position that the ability
to learn and use language is innate and unique to humans. He emphasized the
creative aspect of language, that almost all sentences one hears or produces
are novel. One of his premises was the alleged infinity of sentences in natural
languages, but a less controversial argument can be given: there are tens of
millions of five-word sentences in English, all of which are readily understood
by speakers who have never heard them. Chomsky’s work promised the possibility
of uncovering a very special characteristic of the human mind. But the promise
was qualified by the disclaimer that linguistic theory describes only the
competence of the ideal speaker. Many psycholinguists spent countless hours
during the 0s and 0s seeking the traces of underlying competence beneath the
untidy performances of actual speakers. During the 0s, as Chomsky frequently
revised his theories of syntax and semantics in significant ways, and numerous
alternative linguistic models were under consideration, psychologists generated
a range of productive research problems that are increasingly remote from the
Chomskyan beginnings. Contemporary psycholinguistics addresses phonetic,
phonological, syntactic, semantic, and pragmatic influences on language
processing. Few clear conclusions of philosophical import have been
established. For example, several decades of animal research have shown that
other species can use significant portions of human language, but controversy
abounds over how central those portions are to language. Studies now clearly
indicate the importance of word frequency and coarticulation, the dependency of
a hearer’s identification of a sound as a particular phoneme, or of a visual
pattern as a particular letter, not only on the physical features of the
pattern but on the properties of other patterns not necessarily adjacent.
Physically identical patterns may be heard as a d in one context and a t in
another. It is also accepted that at least some of the human lignuistic
abilities, particularly those involved in reading and speech perception, are
relatively isolated from other cognitive processes. Infant studies show that
children as young as eight months learn statistically important patterns characteristic
of their natural language suggesting a
complex set of mechanisms that are automatic and invisible to us.
Pufendorf, S., G.
historian and theorist of natural law. Pufendorf was influenced by both Grotius
and Hobbes. He portrayed people as contentious and quarrelsome, yet as needing
one another’s company and assistance. Natural law shows how people can live
with one another while pursuing their own conflicting projects. To minimize
religious disputes about morals, Pufendorf sought a way of deriving laws of
nature from observable facts alone. Yet he thought divine activity essential to
morality. He opened his massive Latin treatise On the Law of Nature and of
Nations 1672 with a voluntarist account of God’s creation of the essence of
mankind: given that we have the nature God gave us, certain laws must be valid
for us, but only God’s will determined our nature. As a result, our nature
indicates God’s will for us. Hence observable facts about ourselves show us
what laws God commands us to obey. Because we so obviously need one another’s
assistance, the first law is to increase our sociability, i.e. our willingness
to live together. All other laws indicate acts that would bring about this end.
In the course of expounding the laws he thought important for the development
of social life to the high cultural level our complex nature points us toward,
Pufendorf analyzed all the main points that a full legal system must cover. He
presented the rudiments of laws of marriage, property, inheritance, contract, and
international relations in both war and peace. He also developed the Grotian
theory of personal rights, asserting for the first time that rights are
pointless unless for each right there are correlative duties binding on others.
Taking obligation as his fundamental concept, he developed an important
distinction between perfect and imperfect duties and rights. And in working out
a theory of property he suggested the first outlines of a historical sociology
of wealth later developed by Adam Smith. Pufendorf’s works on natural law were
textbooks for all of Europe for over a century and were far more widely read
than any other treatments of the subject.
pulchrum -- beauty, an aesthetic property commonly
thought of as a species of aesthetic value. As such, it has been variously
thought to be 1 a simple, indefinable property that cannot be defined in terms
of any other properties; 2 a property or set of properties of an object that
makes the object capable of producing a certain sort of pleasurable experience in
any suitable perceiver; or 3 whatever produces a particular sort of pleasurable
experience, even though what produces the experience may vary from individual
to individual. It is in this last sense that beauty is thought to be “in the
eye of the beholder.” If beauty is a simple, indefinable property, as in 1,
then it cannot be defined conceptually and has to be apprehended by intuition
or taste. Beauty, on this account, would be a particular sort of aesthetic
property. If beauty is an object’s Bayle, Pierre beauty 75 75 capacity to produce a special sort of
pleasurable experience, as in 2, then it is necessary to say what properties
provide it with this capacity. The most favored candidates for these have been
formal or structural properties, such as order, symmetry, and proportion. In
the Philebus Plato argues that the form or essence of beauty is knowable,
exact, rational, and measurable. He also holds that simple geometrical shapes,
simple colors, and musical notes all have “intrinsic beauty,” which arouses a
pure, “unmixed” pleasure in the perceiver and is unaffected by context. In the
sixteenth and seventeenth centuries many treatises were written on individual
art forms, each allegedly governed by its own rules. In the eighteenth century,
Hutcheson held that ‘beauty’ refers to an “idea raised in us,” and that any
object that excites this idea is beautiful. He thought that the property of the
object that excites this idea is “uniformity in variety.” Kant explained the
nature of beauty by analyzing judgments that something is beautiful. Such
judgments refer to an experience of the perceiver. But they are not merely
expressions of personal experience; we claim that others should also have the
same experience, and that they should make the same judgment i.e., judgments
that something is beautiful have “universal validity”. Such judgments are
disinterested determined not by any
needs or wants on the part of the perceiver, but just by contemplating the mere
appearance of the object. These are judgments about an object’s free beauty,
and making them requires using only those mental capacities that all humans
have by virtue of their ability to communicate with one another. Hence the
pleasures experienced in response to such beauty can in principle be shared by
anyone. Some have held, as in 3, that we apply the term ‘beautiful’ to things
because of the pleasure they give us, and not on the basis of any specific
qualities an object has. Archibald Alison held that it is impossible to find
any properties common to all those things we call beautiful. Santayana believed
beauty is “pleasure regarded as a quality of a thing,” and made no pretense
that certain qualities ought to produce that pleasure. The Grecian term to
kalon, which is often tr. as ‘beauty’, did not refer to a thing’s autonomous
aesthetic value, but rather to its “excellence,” which is connected with its
moral worth and/or usefulness. This concept is closer to Kant’s notion of
dependent beauty, possessed by an object judged as a particular kind of thing such
as a beautiful cat or a beautiful horse, than it is to free beauty, possessed
by an object judged simply on the basis of its appearance and not in terms of
any concept of use
punishment, a distinctive
form of legal sanction, distinguished first by its painful or unpleasant nature
to the offender, and second by the ground on which the sanction is imposed,
which must be because the offender offended against the norms of a society.
None of these three attributes is a strictly necessary condition for proper use
of the word ‘punishment’. There may be unpleasant consequences visited by
nature upon an offender such that he might be said to have been “punished
enough”; the consequences in a given case may not be unpleasant to a particular
offender, as in the punishment of a masochist with his favorite form of
self-abuse; and punishment may be imposed for reasons other than offense
against society’s norms, as is the case with punishment inflicted in order to
deter others from like acts. The “definitional stop” argument in discussions of
punishment seeks to tie punishment analytically to retributivism. Retributivism
is the theory that punishment is justified by the moral desert of the offender;
on this view, a person who culpably does a wrongful action deserves punishment,
and this desert is a sufficient as well as a necessary condition of just
punishment. Punishment of the deserving, on this view, is an intrinsic good
that does not need to be justified by any other good consequences such
punishment may achieve, such as the prevention of crime. Retributivism is not
to be confused with the view that punishment satisfies the feelings of vengeful
citizens nor with the view that punishment preempts such citizens from taking
the law into their own hands by vigilante action these latter views being utilitarian.
Retributivism is also not the view sometimes called “weak” or “negative”
retributivism that only the deserving are to be punished, for desert on such a
view typically operates only as a limiting and not as a justifying condition of
punishment. The thesis known as the “definitional stop” says that punishment
must be retributive in its justification if it is to be punishment at all. Bad
treatment inflicted in order to prevent future crime is not punishment but
deserves another name, usually ‘telishment’. The dominant justification of
non-retributive punishment or telishment is deterrence. The good in whose name
the bad of punishing is justified, on this view, is prevention of future
criminal acts. If punishment is inflicted to prevent the offender from
committing future criminal acts, it is styled “specific” or “special”
deterrence; if punishment is inflicted to prevent others from committing future
criminal acts, it is styled “general” deterrence. In either case, punishment of
an action is justified by the future effect of that punishment in deterring
future actors from committing crimes. There is some vagueness in the notion of
deterrence because of the different mechanisms by which potential criminals are
influenced not to be criminals by the example of punishment: such punishment
may achieve its effects through fear or by more benignly educating those
would-be criminals out of their criminal desires.
Putnam, Hilary b.6, philosopher who has made significant
contributions to the philosophies of language, science, and mind, and to
mathematical logic and metaphysics. He completed his Ph.D. in 1 at the of California Los Angeles and has taught at
Northwestern, Princeton, MIT, and Harvard. In the late 0s he contributed with
Martin Davis and Julia Robinson to a proof of the unsolvability of Hilbert’s
tenth problem completed in 0 by Yuri Matiyasevich. Rejecting both Platonism and
conventionalism in mathematics, he explored the concepts of mathematical truth
and logical necessity on the assumption that logic is not entirely immune from
empirical revision e.g., quantum
mechanics may require a rejection of classical logic. In the 0s and 0s he
advanced functionalism, an original theory of mind in which human beings are
conceived as Turing machines computers and mental states are functional or 759 computational states. While this theory
is presupposed by much contemporary research in cognitive science, Putnam
himself in Representation and Reality, 8 abandoned the view, arguing that
genuine intentionality cannot be reduced to computational states because the
content of beliefs is a determined by facts external to the individual and b
individuatable only by interpreting our belief system as a whole meaning
holism. Putnam’s criticism of functionalism relies on the “new theory of
reference” sometimes called the “causal”
or “direct” theory that he and Kripke
working independently developed during the late 0s and early 0s and that is
today embraced by many philosophers and scientists. In “The Meaning of
‘Meaning’ ” 5 Putnam claims that the reference of natural kind terms like
‘water’ is determined by facts about the world
the microphysical structure of water H2O and the linguistic practices of
speakers and not by the internal mental states
of speakers. Early in his career, Putnam championed scientific realism,
rejecting conventionalism and arguing that without a realist commitment to
theoretical entities e.g., electrons the success of science would be a
“miracle.” In 6 he famously abandoned metaphysical realism in favor of
“internal realism,” which gives up commitment to mind-independent objects and
relativizes ontology to conceptual schemes. In a series of model-theoretic
arguments, Putnam challenged the metaphysical realist assumption that an
epistemically ideal theory might be false, claiming that it requires an
implausibly “magical” theory of reference. To the same end, he sought to
demonstrate tha
t we are not “brains in a
vat” and that radical skepticism is incoherent Reason, Truth and History, 1.
More recently, he has emphasized conceptual relativity in his attack on
metaphysical realism’s commitment to “one true theory” and, in his Dewey
Lectures 4, has defended direct perceptual realism, showing his allegiance to
everyday “realism.” There is growing appreciation of the underlying unity in
Putnam’s work that helps correct his reputation for “changing his mind.” He has
consistently sought to do justice both to the “real world” of common sense and
science and to distinctly human ways of representing that world. In the 0s his
energies were increasingly directed to our “moral image of the world.” Leading
a revival of pragmatism, he has attacked
the factvalue dichotomy, articulating a moral view that resists both relativism
and authoritarianism. Putnam’s influence now extends beyond philosophers and
scientists, to literary theorists, cognitive linguists, and theologians.
Pyrrho of Elis, Grecian
philosopher, regarded as the founder of Skepticism. Like Socrates, he wrote
nothing, but impressed many with provocative ideas and calm demeanor. His
equanimity was admired by Epicurus; his attitude of indifference influenced
early Stoicism; his attack on knowledge was taken over by the skeptical
Academy; and two centuries later, a revival of Skepticism adopted his name.
Many of his ideas were anticipated by earlier thinkers, notably Democritus. But
in denying the veracity of all sensations and beliefs, Pyrrho carried doubt to
new and radical extremes. According to ancient anecdote, which presents him as
highly eccentric, he paid so little heed to normal sensibilities that friends
often had to rescue him from grave danger; some nonetheless insisted he lived
into his nineties. He is also said to have emulated the “naked teachers” as the
Hindu Brahmans were called by Grecians whom he met while traveling in the
entourage of Alexander the Great. Pyrrho’s chief exponent and publicist was
Timon of Phlius c.325c.235 B.C.. His bestpreserved work, the Silloi “Lampoons”,
is a parody in Homeric epic verse that mocks the pretensions of numerous
philosophers on an imaginary visit to the underworld. According to Timon,
Pyrrho was a “negative dogmatist” who affirmed that knowledge is impossible,
not because our cognitive apparatus is flawed, but because the world is
fundamentally indeterminate: things themselves are “no more” cold than hot, or
good than bad. But Timon makes clear that the key to Pyrrho’s Skepticism, and a
major source of his impact, was the ethical goal he sought to achieve: by
training himself to disregard all perception and values, he hoped to attain
mental tranquility.
Pythagoras, the most
famous of the pre-Socratic Grecian philosophers. He emigrated from the island
of Samos off Asia Minor to Croton southern Italy in 530. There he founded societies
based on a strict way of life. They had great political impact in southern
Italy and aroused opposition that resulted in the burning of their meeting
houses and, ultimately, in the societies’ disappearance in the fourth century
B.C. Pythagoras’s fame grew exponentially with the pasage of time. Plato’s
immediate successors in the Academy saw true philosophy as an unfolding of the
original insight of Pythagoras. By the time of Iamblichus late third century
A.D., Pythagoreanism and Platonism had become virtually identified. Spurious
writings ascribed both to Pythagoras and to other Pythagoreans arose beginning
in the third century B.C. Eventually any thinker who saw the natural world as
ordered according to pleasing mathematical relations e.g., Kepler came to be
called a Pythagorean. Modern scholarship has shown that Pythagoras was not a
scientist, mathematician, or systematic philosopher. He apparently wrote
nothing. The early evidence shows that he was famous for introducing the
doctrine of metempsychosis, according to which the soul is immortal and is
reborn in both human and animal incarnations. Rules were established to purify
the soul including the prohibition against eating beans and the emphasis on
training of the memory. General reflections on the natural world such as
“number is the wisest thing” and “the most beautiful, harmony” were preserved
orally. A belief in the mystical power of number is also visible in the
veneration for the tetractys tetrad: the numbers 14, which add up to the sacred
number 10. The doctrine of the harmony of the spheres that the heavens move in accord with number
and produce music may go back to
Pythagoras. It is often assumed that there must be more to Pythagoras’s thought
than this, given his fame in the later tradition. However, Plato refers to him
only as the founder of a way of life Republic 600a9. In his account of
pre-Socratic philosophy, Aristotle refers not to Pythagoras himself, but to the
“so-called Pythagoreans” whom he dates in the fifth century.
quale: a property of a
mental state or event, in particular of a sensation and a perceptual state,
which determine “what it is like” to have them. Sometimes ‘phenomenal
properties’ and ‘qualitative features’ are used with the same meaning. The felt
difference between pains and itches is said to reside in differences in their
“qualitative character,” i.e., their qualia. For those who accept an
“actobject” conception of perceptual experience, qualia may include such
properties as “phenomenal redness” and “phenomenal roundness,” thought of as
properties of sense-data, “phenomenal objects,” or portions of the visual
field. But those who reject this conception do not thereby reject qualia; a
proponent of the adverbial analysis of perceptual experience can hold that an
experience of “sensing redly” is so in virtue of, in part, what qualia it has,
while denying that there is any sense in which the experience itself is red.
Qualia are thought of as non-intentional, i.e., non-representational, features
of the states that have them. So in a case of “spectrum inversion,” where one
person’s experiences of green are “qualitatively” just like another person’s
experiences of red, and vice versa, the visual experiences the two have when
viewing a ripe tomato would be alike in their intentional features both would
be of a red, round, bulgy surface, but would have different qualia. Critics of
physicalist and functionalist accounts of mind have argued from the possibility
of spectrum inversion and other kinds of “qualia inversion,” and from such
facts as that no physical or functional description will tell one “what it is
like” to smell coffee, that such accounts cannot accommodate qualia. Defenders
of such accounts are divided between those who claim that their accounts can
accommodate qualia and those who claim that qualia are a philosophical myth and
thus that there are none to accommodate.
qualitative predicate, a
kind of predicate postulated in some attempts to solve the grue paradox. 1 On
the syntactic view, a qualitative predicate is a syntactically more or less
simple predicate. Such simplicity, however, is relative to the choice of
primitives in a language. In English, ‘green’ and ‘blue’ are primitive, while
‘grue’ and ‘bleen’ must be introduced by definitions ‘green and first examined
before T, or blue otherwise’, ‘blue and first examined before T, or green
otherwise’, respectively. In other languages, ‘grue’ and ‘bleen’ may be
primitive and hence “simple,” while ‘green’ and ‘blue’ must be introduced by
definitions ‘grue and first examined before T, or bleen otherwise’, ‘bleen and
first examined before T, or grue otherwise’, respectively. 2 On the semantic
view, a qualitative predicate is a predicate to which there corresponds a
property that is “natural” to us or of easy semantic access. The quality of
greenness is easy and natural; the quality of grueness is strained. 3 On the
ontological view, a qualitative predicate is a predicate to which there
corresponds a property that is woven into the causal or modal structure of
reality in a way that gruesome properties are not.
qualities, properties or
characteristics. There are three specific philosophical senses. 1 Qualities are
physical properties, logical constructions of physical properties, or
dispositions. Physical properties, such as mass, shape, and electrical charge,
are properties in virtue of which objects can enter into causal relations.
Logical constructions of physical properties include conjunctions and
disjunctions of them; being 10 # .02 cm long is a disjunctive property. A
disposition of an object is a potential for the object to enter into a causal
interaction of some specific kind under some specific condition; e.g., an
object is soluble in water if and only if it would dissolve were it in enough
pure water. Locke held a very complex theory of powers. On Locke’s theory, the
dispositions of objects are a kind of power and the human will is a kind of
power. However, the human will is not part of the modern notion of disposition.
So, predicating a disposition of an object implies a subjunctive conditional of
the form: if such-and-such were to happen to the object, then so-and-so would
happen to it; that my vase is fragile implies that if my vase were to be hit
sufficiently hard then it would break. Whether physical properties are distinct
from dispositions is disputed. Three sorts of qualities are often
distinguished. Primary qualities are physical properties or logical
constructions from physical properties. Secondary qualities are dispositions to
produce sensory experiences of certain phenomenal sorts under appropriate
conditions. The predication of a secondary quality, Q, to an object implies
that if the object were to be perceived under normal conditions then the object
would appear to be Q to the perceivers: if redness is a secondary quality, then
that your coat is red implies that if your coat were to be seen under normal
conditions, it would look red. Locke held that the following are secondary
qualities: colors, tastes, smells, sounds, and warmth or cold. Tertiary qualities
are dispositions that are not secondary qualities, e.g. fragility. Contrary to
Locke, the color realist holds that colors are either primary or tertiary
qualities; so that x is yellow is logically independent of the fact that x
looks yellow under normal conditions. Since different spectral reflectances
appear to be the same shade of yellow, some color realists hold that any shade
of yellow is a disjunctive property whose components are spectral reflectances.
2 Assuming a representative theory of perception, as Locke did, qualities have
two characteristics: qualities are powers or dispositions of objects to produce
sensory experiences sensedata on some theories in humans; and, in sensory
experience, qualities are represented as intrinsic properties of objects.
Instrinsic properties of objects are properties that objects have independently
of their environment. Hence an exact duplicate of an object has all the
intrinsic properties of the original, and an intrinsic property of x never has
the form, x-stands-in-suchand-such-a-relation-to-y. Locke held that the primary
qualities are extension size, figure shape, motion or rest, solidity
impenetrability, and number; the primary qualities are correctly represented in
perception as intrinsic features of objects, and the secondary qualities listed
in 1 are incorrectly represented in perception as intrinsic features of
objects. Locke seems to have been mistaken in holding that number is a quality
of objects. Positional qualities are qualities defined in terms of the relative
positions of points in objects and their surrounding: shape, size, and motion
and rest. Since most of Locke’s primary qualities are positional, some
non-positional quality is needed to occupy positions. On Locke’s account,
solidity fulfills this role, although some have argued Hume that solidity is
not a primary quality. 3 Primary qualities are properties common to and
inseparable from all matter; secondary qualities are not really qualities in
objects, but only powers of objects to produce sensory effects in us by means
of their primary qualities. This is another use of ‘quality’ by Locke, where
‘primary’ functions much like ‘real’ and real properties are given by the
metaphysical assumptions of the science of Locke’s time. Qualities are distinct
from representations of them in predications. Sometimes the same quality is
represented in different ways by different predications: ‘That is water’ and
‘That is H2O’. The distinction between qualities and the way they are
represented in predications opens up the Lockean possibility that some
qualities are incorrectly represented in some predications. Features of
predications are sometimes used to define a quality; dispositions are sometimes
defined in terms of subjunctive conditionals see definition of ‘secondary
qualities’ in 1, and disjunctive properties are defined in terms of disjunctive
predications. Features of predications are also used in the following
definition of ‘independent qualities’: two qualities, P and Q, are independent
if and only if, for any object x, the predication of P and of Q to x are
logically independent i.e., that x is P and that x is Q are logically
independent; circularity and redness are independent, circularity and
triangularity are dependent. If two determinate qualities, e.g., circularity
and triangularity, belong to the same determinable, say shape, then they are
dependent, but if two determinate qualities, e.g., squareness and redness,
belong to different determinables, say shape and color, they are independent.
Quantification: H. P.
Grice, “Every nice girl loves a sailor.” -- the application of one or more
quantifiers e.g., ‘for all x’, ‘for some y’ to an open formula. A
quantification or quantified sentence results from first forming an open
formula from a sentence by replacing expressions belonging to a certain class
of expressions in the sentences by variables whose substituends are the
expressions of that class and then prefixing the formula with quantifiers using
those variables. For example, from ‘Bill hates Mary’ we form ‘x hates y’, to
which we prefix the quantifiers ‘for all x’ and ‘for some y’, getting the
quantification sentence ‘for all x, for some y, x hates y’ ‘Everyone hates
someone’. In referential quantification only terms of reference may be replaced
by variables. The replaceable terms of reference are the substituends of the
variables. The values of the variables are all those objects to which reference
could be made by a term of reference of the type that the variables may
replace. Thus the previous example ‘for all x, for some y, x hates y’ is a
referential quantification. Terms standing for people ‘Bill’, ‘Mary’, e.g. are
the substituends of the variables ‘x’ and ‘y’. And people are the values of the
variables. In substitutional quantification any type of term may be replaced by
variables. A variable replacing a term has as its substituends all terms of the
type of the replaced term. For example, from ‘Bill married Mary’ we may form
‘Bill R Mary’, to which we prefix the quantifier ‘for some R’, getting the
substitutional quantification ‘for some R, Bill R Mary’. This is not a
referential quantification, since the substituends of ‘R’ are binary predicates
such as ‘marries’, which are not terms of reference. Referential quantification
is a species of objectual quantification. The truth conditions of
quantification sentences objectually construed are understood in terms of the
values of the variable bound by the quantifier. Thus, ‘for all v, fv’ is true
provided ‘fv’ is true for all values of the variable ‘v’; ‘for some v, fv’ is
true provided ‘fv’ is true for some value of the variable ‘v’. The truth or
falsity of a substitutional quantification turns instead on the truth or
falsity of the sentences that result from the quantified formula by replacing
variables by their substituends. For example, ‘for some R, Bill R Mary’ is true
provided some sentence of the form ‘Bill R Mary’ is true. In classical logic
the universal quantifier ‘for all’ is definable in terms of negation and the
existential quantifier ‘for some’: ‘for all x’ is short for ‘not for some x
not’. The existential quantifier is similarly definable in terms of negation
and the universal quantifier. In intuitionistic logic, this does not hold. Both
quantifiers are regarded as primitive.
quantifying in, use of a
quantifier outside of an opaque construction to attempt to bind a variable
within it, a procedure whose legitimacy was first questioned by Quine. An
opaque construction is one that resists substitutivity of identity. Among
others, the constructions of quotation, the verbs of propositional attitude,
and the logical modalities can give rise to opacity. For example, the position
of ‘six’ in: 1 ‘six’ contains exactly three letters is opaque, since the
substitution for ‘six’ by its codesignate ‘immediate successor of five’ renders
a truth into a falsehood: 1H ‘the immediate successor of five’ contains exactly
three letters. Similarly, the position of ‘the earth’ in: 2 Tom believes that
the earth is habitable is opaque, if the substitution of ‘the earth’ by its
codesignate ‘the third planet from the sun’ renders a sentence that Tom would
affirm into one that he would deny: 2H Tom believes that the third planet from
the sun is habitable. Finally, the position of ‘9’ and of ‘7’ in: 3 Necessarily
9 7 is opaque, since the substitution of
‘the number of major planets’ for its codesignate ‘9’ renders a truth into a
falsehood: 3H Necessarily the number of major planets 7. Quine argues that since the positions
within opaque constructions resist substitutivity of identity, they cannot
meaningfully be quantified. Accordingly, the following three quantified
sentences are meaningless: 1I Ex ‘x’ 7,
2I Ex Tom believes that x is habitable, 3I Ex necessarily x 7. 1I, 2I, and 3I are meaningless, since the
second occurrence of ‘x’ in each of them does not function as a variable in the
ordinary nonessentialist quantificational way. The second occurrence of ‘x’ in
1I functions as a name that names the twenty-fourth letter of the alphabet. The
second occurrences of ‘x’ in 2I and in 3I do not function as variables, since
they do not allow all codesignative terms as substituends without change of
truth-value. Thus, they may take objects as values but only objects designated
in certain ways, e.g., in terms of their intensional or essential properties.
So, short of acquiescing in an intensionalist or essentialist metaphysics,
Quine argues, we cannot in general quantify into opaque contexts.
quantum logic, the logic
of which the models are certain non-Boolean algebras derived from the
mathematical representation of quantum mechanical systems. The models of
classical logic are, formally, Boolean algebras. This is the central notion of
quantum logic in the literature, although the term covers a variety of modal
logics, dialogics, and operational logics proposed to elucidate the structure
of quantum mechanics and its relation to classical mechanics. The dynamical
quantities of a classical mechanical system position, momentum, energy, etc.
form a commutative algebra, and the dynamical properties of the system e.g.,
the property that the position lies in a specified range, or the property that
the momentum is greater than zero, etc. form a Boolean algebra. The transition
from classical to quantum mechanics involves the transition from a commutative
algebra of dynamical quantities to a noncommutative algebra of so-called
observables. One way of understanding the conceptual revolution from classical
to quantum mechanics is in terms of a shift from the class of Boolean algebras
to a class of non-Boolean algebras as the appropriate relational structures for
the dynamical properties of mechanical systems, hence from a Boolean classical
logic to a non-Boolean quantum logic as the logic applicable to the fundamental
physical processes of our universe. This conception of quantum logic was
developed formally in a classic 6 paper by G. Birkhoff and J. von Neumann
although von Neumann first proposed the idea in 7. The features that
distinguish quantum logic from classical logic vary with the formulation. In
the Birkhoffvon Neumann logic, the distributive law of classical logic fails,
but this is by no means a feature of all versions of quantum logic. It follows
from Gleason’s theorem 7 that the non-Boolean models do not admit two-valued
homomorphisms in the general case, i.e., there is no partition of the dynamical
properties of a quantum mechanical system into those possessed by the system
and those not possessed by the system that preserves algebraic structure, and
equivalently no assignment of values to the observables of the system that
preserves algebraic structure. This result was proved independently for finite
sets of observables by S. Kochen and E. P. Specker 7. It follows that the
probabilities specified by the Born interpretation of the state function of a
quantum mechanical system for the results of measurements of observables cannot
be derived from a probability distribution over the different possible sets of
dynamical properties of the system, or the different possible sets of values
assignable to the observables of which one set is presumed to be actual,
determined by hidden variables in addition to the state function, if these sets
of properties or values are required to preserve algebraic structure. While
Bell’s theorem 4 excludes hidden variables satisfying a certain locality
condition, the Kochen-Specker theorem relates the non-Booleanity of quantum
logic to the impossibility of hidden variable extensions of quantum mechanics,
in which value assignments to the observables satisfy constraints imposed by
the algebraic structure of the observables.
quantum mechanics, also
called quantum theory, the science governing objects of atomic and subatomic
dimensions. Developed independently by Werner Heisenberg as matrix mechanics, 5
and Erwin Schrödinger as wave mechanics, 6, quantum mechanics breaks with
classical treatments of the motions and interactions of bodies by introducing
probability and acts of measurement in seemingly irreducible ways. In the
widely used Schrödinger version, quantum mechanics associates with each
physical system a time-dependent function, called the state function
alternatively, the state vector or Y function. The evolution of the system is
represented by the temporal transformation of the state function in accord with
a master equation, known as the Schrödinger equation. Also associated with a
system are “observables”: in principle measurable quantities, such as position,
momentum, and energy, including some with no good classical analogue, such as
spin. According to the Born interpretation 6, the state function is understood
instrumentally: it enables one to calculate, for any possible value of an
observable, the probability that a measurement of that observable would find
that particular value. The formal properties of observables and state functions
imply that certain pairs of observables such as linear momentum in a given
direction, and position in the same direction are incompatible in the sense
that no state function assigns probability 1 to the simultaneous determination
of exact values for both observables. This is a qualitative statement of the
Heisenberg uncertainty principle alternatively, the indeterminacy principle, or
just the uncertainty principle. Quantitatively, that principle places a precise
limit on the accuracy with which one may simultaneously measure a pair of
incompatible observables. There is no corresponding limit, however, on the
accuracy with which a single observable say, position alone, or momentum alone
may be measured. The uncertainty principle is sometimes understood in terms of
complementarity, a general perspective proposed by Niels Bohr according to
which the connection between quantum phenomena and observation forces our
classical concepts to split into mutually exclusive packages, both of which are
required for a complete understanding but only one of which is applicable under
any particular experimental conditions. Some take this to imply an ontology in
which quantum objects do not actually possess simultaneous values for
incompatible observables; e.g., do not have simultaneous position and momentum.
Others would hold, e.g., that measuring the position of an object causes an
uncontrollable change in its momentum, in accord with the limits on
simultaneous accuracy built into the uncertainty principle. These ways of
treating the principle are not uncontroversial. Philosophical interest arises
in part from where the quantum theory breaks with classical physics: namely,
from the apparent breakdown of determinism or causality that seems to result
from the irreducibly statistical nature of the theory, and from the apparent
breakdown of observer-independence or realism that seems to result from the
fundamental role of measurement in the theory. Both features relate to the
interpretation of the state function as providing only a summary of the
probabilities for various measurement outcomes. Einstein, in particular,
criticized the theory on these grounds, and in 5 suggested a striking thought
experiment to show that, assuming no action-at-a-distance, one would have to
consider the state function as an incomplete description of the real physical
state for an individual system, and therefore quantum mechanics as merely a
provisional theory. Einstein’s example involved a pair of systems that interact
briefly and then separate, but in such a way that the outcomes of various
measurements performed on each system, separately, show an uncanny correlation.
In 1 the physicist David Bohm simplified Einstein’s example, and later 7
indicated that it may be realizable experimentally. The physicist John S. Bell
then formulated a locality assumption 4, similar to Einstein’s, that constrains
factors which might be used in describing the state of an individual system,
so-called hidden variables. Locality requires that in the EinsteinBohm
experiment hidden variables not allow the measurement performed on one system
in a correlated pair immediately to influence the outcome obtained in measuring
the other, spatially separated system. Bell demonstrated that locality in conjunction
with other assumptions about hidden variables restricts the probabilities for
measurement outcomes according to a system of inequalities known as the Bell
inequalities, and that the probabilities of certain quantum systems violate
these inequalities. This is Bell’s theorem. Subsequently several experiments of
the Einstein-Bohm type have been performed to test the Bell inequalities.
Although the results have not been univocal, the consensus is that the
experimental data support the quantum theory and violate the inequalities.
Current research is trying to evaluate the implications of these results,
including the extent to which they rule out local hidden variables. See J.
Cushing and E. McMullin, eds., Philosophical Consequences of Quantum Theory, 9.
The descriptive incompleteness with which Einstein charged the theory suggests
other problems. A particularly dramatic one arose in correspondence between
Schrödinger and Einstein; namely, the “gruesome” Schrödinger cat paradox. Here
a cat is confined in a closed chamber containing a radioactive atom with a
fifty-fifty chance of decaying in the next hour. If the atom decays it triggers
a relay that causes a hammer to fall and smash a glass vial holding a quantity
of 766 prussic acid sufficient to kill
the cat. According to the Schrödinger equation, after an hour the state
function for the entire atom ! relay ! hammer ! glass vial ! cat system is such
that if we observe the cat the probability for finding it alive dead is 50
percent. However, this evolved state function is one for which there is no
definite result; according to it, the cat is neither alive nor dead. How then
does any definite fact of the matter arise, and when? Is the act of observation
itself instrumental in bringing about the observed result, does that result
come about by virtue of some special random process, or is there some other
account compatible with definite results of measurements? This is the so-called
quantum measurement problem and it too is an active area of research.
quasi-demonstratum: The use of ‘quasi-‘ is implicatural. Grice is
implicating this is NOT a demonstratum. By a demonstratum he is having in mind
a Kaplanian ‘dthis’ or ‘dthat.’ Grice was obsessed with this or that. An
abstractum (such as “philosopher”) needs to be attached in a communicatum by
what Grice calls a ‘quasi-demonstrative,’ and for which he uses “φ.” Consider,
Grice says, an utterance, out of the blue, such as ‘The philosopher in the
garden seems bored,’ involving two iota-operators. As there may be more that a
philosopher in a garden in the great big world, the utterer intends his
addressee to treat the utterance as expandable into ‘The A which is φ is
B,’ where “φ” is a quasi-demonstrative epithet to be identified in a particular
context of utterance. The utterer intends that, to identify the denotatum
of “φ” for a particular utterance of ‘The philosopher in the garden seems
bored,’ the addressee wil proceed via the identification of a particular
philosopher, say Grice, as being a good candidate for being the philosopher
meant. The addressee is also intended to identify the candidate for a denotatum
of φ by finding in the candidate a feature, e. g., that of being the garden at
St. John’s, which is intended to be used to yield a composite epithet (‘philosopher
in St. John’s garden’), which in turn fills the bill of being the epithet which
the utterer believes is being uniquely satisfied by the philosopher selected as
the candidate. Determining the denotatum of “φ” standardly involve determining
what feature the utterer believes is uniquely instantiated by the predicate
“philosopher.” This in turn involves satisfying oneself that some particular
feature is in fact uniquely satisfied by a particular actual item, viz. a
particular philosopher such as Grice seeming bored in the garden of St. John’s.
quasi-indicator,
Castañeda’s term for an expression used to ascribe indexical reference to a
speaker or thinker. If John says “I am hungry” it is incorrect to report what
he said with ‘John claims that I am hungry’, since ‘I’, being an indexical,
expresses speaker’s reference, not John’s. However, ‘John claims that John is
hungry’ fails to represent the indexical element of his assertion. Instead, we
use ‘John claims that he himself is hungry’, where ‘he himself’ is a
quasiindicator depicting John’s reference to himself qua self. Because of its
subjective and perspectival character, we cannot grasp the exact content of
another’s indexical reference, yet quasi-indexical representations are possible
since we confront the world through generically the same indexical modes of
presentation. If these modes are irreducible, then quasi-indicators are
indispensable for describing the thoughts and experiences of others. As such,
they are not equivalent to or replaceable by any antecedents occurring outside
the scope of psychological verbs to which they are subordinated.
Quineianism: corners,
also called corner quotes, quasi-quotes, a notational device ] ^ introduced by
Quine Mathematical Logic, 0 to provide a conveniently brief way of speaking
generally about unspecified expressions of such and such kind. For example, a
logician might want a conveniently brief way of saying in the metalanguage that
the result of writing a wedge ‘7’ the dyadic logical connective for a truth-functional
use of ‘or’ between any two well-formed formulas wffs in the object language is
itself a wff. Supposing the Grecian letters ‘f’ and ‘y’ available in the
metalanguage as variables ranging over wffs in the object language, it is
tempting to think that the formation rule stated above can be succinctly
expressed simply by saying that if f and y are wffs, then ‘f 7 y’ is a wff. But
this will not do, for ‘f 7 y’ is not a wff. Rather, it is a hybrid expression
of two variables of the metalanguage and a dyadic logical connective of the
object language. The problem is that putting quotation marks around the Grecian
letters merely results in designating those letters themselves, not, as
desired, in designating the context of the unspecified wffs. Quine’s device of
corners allows one to transcend this limitation of straight quotation since
quasi-quotation, e.g., ]f 7 y^, amounts to quoting the constant contextual
background, ‘# 7 #’, and imagining the unspecified expressions f and y written
in the blanks. Quine, Willard Van Orman
– see Quine, “Reply to H. P. Grice,” --
philosopher and logician, renowned for his rejection of the
analyticsynthetic distinction and for his advocacy of extensionalism,
naturalism, physicalism, empiricism, and holism. Quine took his doctorate in
philosophy at Harvard in 2. After four years of postdoctoral fellowships, he
was appointed to the philosophy faculty at Harvard in 6. There he remained
until he retired from teaching in 8. During six decades Quine published scores
of journal articles and more than twenty books. His writings touch a number of
areas, including logic, philosophy of logic, set theory, philosophy of
language, philosophy of mind, philosophy of science, metaphysics, epistemology,
and ethics. Among his most influential articles and books are “New Foundations
for Mathematical Logic” 6, “Two Dogmas of Empiricism” 1, “Epistemology
Naturalized” 9, and Word and Object 0. In “New Foundations” he develops a set
theory that avoids Russell’s paradox without relying on Russell’s theory of
types. Rather, following Ernst Zermelo, Quine drops the presumption that every
membership condition determines a set. The system of “New Foundations”
continues to be widely discussed by mathematicians. “Two Dogmas” sets out to
repudiate what he sees as two dogmas of logical empiricism. The first is the
so-called analyticsynthetic distinction; the second is a weak form of
reductionism to the effect that each synthetic statement has associated with it
a unique set of confirming experiences and a unique set of infirming
experiences. Against the first dogma, Quine argues that none of the
then-current attempts to characterize analyticity e.g., “a statement is
analytic if and only if it is true solely in virtue of its meaning” do so with
sufficient clarity, and that any similar characterization is likewise doomed to
fail. Against the second dogma, Quine argues that a more accurate account of
the relation between the statements of a theory and experience is holistic
rather than reductionistic, that is, only as a corporate body do the statements
of a theory face the tribunal of experience. Quine concludes that the effects
of rejecting these two dogmas of empiricism are 1 a blurring of the supposed
boundary between speculative metaphysics and natural science and 2 a shift
toward pragmatism. In “Epistemology Naturalized” Quine argues in favor of
naturalizing epistemology: old-time epistemology first philosophy has failed in
its attempt to ground science on something firmer than science and should, therefore,
be replaced by a scientific account of how we acquire our overall theory of the
world and why it works so well. In Word and Object, Quine’s most famous book,
he argues in favor of 1 naturalizing epistemology, 2 physicalism as against
phenomenalism and mindbody dualism, and 3 extensionality as against
intensionality. He also 4 develops a behavioristic conception of
sentence-meaning, 5 theorizes about language learning, 6 speculates on the
ontogenesis of reference, 7 explains various forms of ambiguity and vagueness,
8 recommends measures for regimenting language so as to eliminate ambiguity and
vagueness as well as to make a theory’s logic and ontic commitments perspicuous
“to be is to be the value of a bound variable”, 9 argues against quantified modal
logic and the essentialism it presupposes, 10 argues for Platonic realism in
mathematics, 11 argues for scientific realism and against instrumentalism, 12
develops a view of philosophical analysis as explication, 13 argues against
analyticity and for holism, 14 argues against countenancing propositions, and
15 argues that the meanings of theoretical sentences are indeterminate and that
the reference of terms is inscrutable. Quine’s subsequent writings have largely
been devoted to summing up, clarifying, and expanding on themes found in Word
and Object.
A.M. Quinton’s
Gedanke Experiment: from “Spaces and
Times,” Philosophy.“hardly Thought Out” – Is this apriori or a posteriori? H.
P. Grice. Space is ordinarily seen to be a
unique individual. All real things are contained in one and the same space, and
all spaces are part of the one space. In principle, every place can be reached
from every other place by traveling through intermediate places. The spatial
relation is symmetrical. Grice’s friend, A. M. Quinton devised a thought
experiment to challenge this picture. Suppose that we have richly coherent and
connected experience in our dreams just as we have in waking life, so that it
becomes arbitrary to claim that our dream experience is not of an objectively
existing world like the world of our waking experience. If the space of my
waking world and my dream world are not mutually accessible, it is unlikely
that we are justified in claiming to be living in a single spatially isolated
world. Hence, space is not essentially singular. In assessing this account, we
might distinguish between systematic and public physical space and fragmentary
and private experiential space. The two-space myth raises questions about how
we can justify moving from experiential space to objective space in the world
as it is. “We can at least conceive circumstances in which we should have good
reason to say that we know of real things located in two distinct spaces.”
Quinton, “Spaces and Times,” Philosophy 37
Radix
-- Radix
-- Grice often talked about logical atomism and molecular propositions – and
radix – which is an atomic metaphor -- Democritus, Grecian preSocratic
philosopher. He was born at Abdera, in Thrace. Building on Leucippus and his
atomism, he developed the atomic theory in The Little World-system and numerous
other writings. In response to the Eleatics’ argument that the impossibility of
not-being entailed that there is no change, the atomists posited the existence
of a plurality of tiny indivisible beings
the atoms and not-being the void, or empty space. Atoms do not come
into being or perish, but they do move in the void, making possible the
existence of a world, and indeed of many worlds. For the void is infinite in
extent, and filled with an infinite number of atoms that move and collide with
one another. Under the right conditions a concentration of atoms can begin a
vortex motion that draws in other atoms and forms a spherical heaven enclosing
a world. In our world there is a flat earth surrounded by heavenly bodies
carried by a vortex motion. Other worlds like ours are born, flourish, and die,
but their astronomical configurations may be different from ours and they need
not have living creatures in them. The atoms are solid bodies with countless
shapes and sizes, apparently having weight or mass, and capable of motion. All
other properties are in some way derivative of these basic properties. The
cosmic vortex motion causes a sifting that tends to separate similar atoms as
the sea arranges pebbles on the shore. For instance heavier atoms sink to the
center of the vortex, and lighter atoms such as those of fire rise upward.
Compound bodies can grow by the aggregations of atoms that become entangled
with one another. Living things, including humans, originally emerged out of
slime. Life is caused by fine, spherical soul atoms, and living things die when
these atoms are lost. Human culture gradually evolved through chance
discoveries and imitations of nature. Because the atoms are invisible and the
only real properties are properties of atoms, we cannot have direct knowledge
of anything. Tastes, temperatures, and colors we know only “by convention.” In
general the senses cannot give us anything but “bastard” knowledge; but there
is a “legitimate” knowledge based on reason, which takes over where the senses
leave off presumably demonstrating that
there are atoms that the senses cannot testify of. Democritus offers a causal
theory of perception sometimes called
the theory of effluxes accounting for
tastes in terms of certain shapes of atoms and for sight in terms of
“effluences” or moving films of atoms that impinge on the eye. Drawing on both
atomic theory and conventional wisdom, Democritus develops an ethics of
moderation. The aim of life is equanimity euthumiê, a state of balance achieved
by moderation and proportionate pleasures. Envy and ambition are incompatible
with the good life. Although Democritus was one of the most prolific writers of
antiquity, his works were all lost. Yet we can still identify his atomic theory
as the most fully worked out of pre-Socratic philosophies. His theory of matter
influenced Plato’s Timaeus, and his naturalist anthropology became the
prototype for liberal social theories. Democritus had no immediate successors,
but a century later Epicurus transformed his ethics into a philosophy of
consolation founded on atomism. Epicureanism thus became the vehicle through
which atomic theory was transmitted to the early modern period.

philosopher of logic and mathematics. His primary interests were in logic and
philosophy, but decades after his untimely death two of his publications
sparked new branches of economics, and in pure mathematics his combinatorial
theorems gave rise to “Ramsey theory” Economic Journal 7, 8; Proc. London Math.
Soc., 8. During his lifetime Ramsey’s philosophical reputation outside
Cambridge was based largely on his architectural reparation of Whitehead and
Russell’s Principia Mathematica, strengthening its claim to reduce mathematics
to the new logic formulated in Volume 1
a reduction rounded out by Vitters’s assessment of logical truths as
tautologous. Ramsey clarified this logicist picture of mathematics by radically
simplifying Russell’s ramified theory of types, eliminating the need for the
unarguable axiom of reducibility Proc. London Math. Soc., 5. His philosophical
work was published mostly after his death. The canon, established by Richard
Braithwaite The Foundations of Mathematics . . . , 1, remains generally intact
in D. H. Mellor’s edition Philosophical Papers, 0. Further writings of varying
importance appear in his Notes on Philosophy, Probability and Mathematics M. C.
Galavotti, ed., 1 and On Truth Nicholas Rescher and Ulrich Majer, eds., 1. As
an undergraduate Ramsey observed that the redundancy account of truth “enables
us to rule out at once some theories of truth such as that ‘to be true’ means
‘to work’ or ‘to cohere’ since clearly ‘p works’ and ‘p coheres’ are not
equivalent to ‘p’.” Later, in the canonical “Truth and Probability” 6, he
readdressed to knowledge and belief the main questions ordinarily associated
with truth, analyzing probability as a mode of judgment in the framework of a
theory of choice under uncertainty. Reinvented and acknowledged by L. J. Savage
Foundations of Statistics, 4, this forms the theoretical basis of the currently
dominant “Bayesian” view of rational decision making. Ramsey cut his
philosophical teeth on Vitters’s Tractatus LogicoPhilosophicus. His translation
appeared in 2; a long critical notice of the work 3 was his first substantial
philosophical publication. His later role in Vitters’s rejection of the
Tractatus is acknowledged in the foreword to Philosophical Investigations 3.
The posthumous canon has been a gold mine. An example: “Propositions” 9,
reading the theoretical terms T, U, etc. of an axiomatized scientific theory as
variables, sees the theory’s content as conveyed by a “Ramsey sentence” saying
that for some T, U, etc., the theory’s axioms are true, a sentence in which all
extralogical terms are observational. Another example: “General Propositions
and Causality” 9, offering in a footnote the “Ramsey test” for acceptability of
conditionals, i.e., add the if-clause to your ambient beliefs minimally
modified to make the enlarged set self-consistent, and accept the conditional
if the then-clause follows. Refs:

Ramus, Petrus, in ,
Pierre de La Ramée, philosopher who questioned the authority of Aristotle and
influenced the methods and teaching of logic through the seventeenth century.
In 1543 he published his Dialecticae institutiones libri XV, and in 1555 reworked
it as Dialectique the first
philosophical work in . He was appointed by François I as the first Regius
Professor of the of Paris, where he
taught until he was killed in the St. Bartholomew’s Day Massacre in 1572. Ramus
doubted that we can apodictically intuit the major premises required for
Aristotle’s rational syllogism. Turning instead to Plato, Ramus proposed that a
“Socratizing” of logic would produce a more workable and fruitful result. As
had Agricola and Sturm, he reworked the rhetorical and liberal arts traditions’
concepts of “invention, judgment, and practice,” placing “method” in the center
of judgment. Proceeding in these stages, we can “read” nature’s “arguments,”
because they are modeled on natural reasoning, which in turn can emulate the
reasoning by which God creates. Often his results were depicted graphically in
tables as in chapter IX of Hobbes’s Leviathan. When carefully done they would
show both what is known and where gaps require further investigation; the
process from invention to judgment is continuous. Ramus’s works saw some 750
editions in one century, fostering the “Ramist” movement in emerging Protestant
universities and the colonies. He
influenced Bacon, Hobbes, Milton, Methodism, Cambridge Platonism, and Alsted in
Europe, and Hooker and Congregationalism in Puritan America. Inconsistencies
make him less than a major figure in the history of logic, but his many works
and their rapid popularity led to philosophical and educational efforts to
bring the world of learning to the “plain man” by using the vernacular, and by
more closely correlating the rigor of philosophy with the memorable and
persuasive powers of rhetoric; he saw this goal as Socratic.
Rashdall, Hastings 18584,
English historian, theologian, and personal idealist. While acknowledging that
Berkeley needed to be corrected by Kant, Rashdall defended Berkeley’s thesis
that objects only exist for minds. From this he concluded that there is a
divine mind that guarantees the existence of nature and the objectivity of morality.
In his most important philosophical work, The Theory of Good and Evil 7,
Rashdall argued that actions are right or wrong according to whether they
produce well-being, in which pleasure as well as a virtuous disposition are
constituents. Rashdall coined the name ‘ideal utilitarianism’ for this view.

Teutonic kausjun passed

Slavonic. Insofar as a philosopher explains and predicts the actum as
consequences of a choice, which are themselves explained in terms of alleged
reasons, it must depict agents as to some extent rational. Rationality, like
reasons, involves evaluation, and just as one can assess the rationality of
individual choices, so one can assess the rationality of social choices and
examine how they are and ought to be related to the preferences and judgments
of the actor. In addition, there are intricate questions concerning rationality
in ‘strategic’ situations in which outcomes depend on the choices of multiple
individuals. Since rationality is a central concept in branches of philosophy
such as Grice’s pragmatics, action theory, epistemology, ethics, and philosophy
of mind, studies of rationality frequently cross the boundaries various
branches of philosophy. The barebones theory of rationality takes an
agent’s preferences,
i. e. his rankings of states of affairs, to be rational if they are complete
and transitive, and it takes the agent’s choice to be rational if the agent
does not prefer any feasible alternative to the one he chooses. Such a theory
of rationality is clearly too weak. It says nothing about belief or what
rationality implies when the agent does not know (with certainty) everything
relevant to his choice. It may also be too strong, since there is nothing
irrational about having incomplete preferences in situations involving
uncertainty. Sometimes it is rational to suspend judgment and to refuse to rank
alternatives that are not well understood. On the other hand, transitivity is a
plausible condition, and the so-called “money pump” argument demonstrates that
if one’s preferences are intransitive and one is willing to make exchanges,
then one can be exploited. Suppose an agent A prefers X to Y, Y to Z and Z to X,
and that A will pay some small amount of money $P to
exchange Y for X, Z for Y,
and X for Z. That means that, starting
with Z, A will pay $P for Y,
then $P again for X, then $P again
for Z and so on. An agent need not be this stupid. He will
instead refuse to trade or adjust his preferences to eliminate the
intransitivity. On the other hand, there is evidence that an agent’s
preferences are not in fact transitive. Such evidence does not establish that
transitivity is not a requirement of rationality. It may show instead that an
agent may sometimes not be rational. In, e. g. the case of preference
reversals,” it seems plausible that the agent in fact makes the ‘irrational
choice.’ Evidence of persistent violations of transitivity is disquieting,
since standards of rationality should not be impossibly high. A further difficulty with the barebones theory
of rationality concerns the individuation of the objects of preference or
choice. Consider e. g. data from a multi-stage ultimatum game. Suppose A can
propose any division of $10 between A and B. B can
accept or reject A’s proposal. If B rejects
the proposal, the amount of money drops to $5, and B gets to
offer a division of the $5 which A can accept or reject.
If A rejects B’s offer, both players get
nothing. Suppose that A proposes to divide the money with $7
for A and $3 for B. B declines
and offers to split the $5 evenly, with $2.50 for each. Behaviour such as this
is, in fact, common. Assuming that B prefers more money to
less, these choices appear to be a violation of transitivity. B prefers
$3 to $2.50, yet declines $3 for certain for $2.50 (with some slight chance
of A declining and B getting nothing).
But the objects of choice are not just quantities of money. B is
turning down $3 as part of “a raw deal” in favour of $2.50 as part of a fair
arrangement. If the objects of choice are defined in this way, there is no
failure of transitivity. This plausible
observation gives rise to a serious conceptual problem that Grice thinks he can
solve. Unless there are constraints on how the objects of choice are
individuated, conditions of rationality such as transitivity are empty. A’s
choice of X over Y, Y over Z and Z over X does
not violate transitivity if “X when the alternative is Y”
is not the same object of choice as “X when the alternative
is Z”. A further substantive principle of rationality isrequired
to limit how alternatives are individuated or to require that agents be
indifferent between alternatives such as “X when the alternative
is Y” and “X when the alternative is Z.”
To extend the theory of rationality to circumstances involving risk (where
the objects of choice are lotteries with known probabilities) and uncertainty
(where agents do not know the probabilities or even all the possible outcomes
of their choices) requires a further principle of rationality, as well as a
controversial technical simplification. Subjective Bayesians suppose that the
agent in circumstances of uncertainty has well-defined subjective probabilities
(degrees of belief) over all the payoffs and thus that the objects of choice
can be modeled as lotteries, just as in circumstances involving risk, though
with subjective probabilities in place of objective probabilities. The most
important of the axioms needed for the theory of rational choice under
conditions of risk and uncertainty is the independence condition. The
preferences of a rational agent between two lotteries that differ in only one
outcome should match his preferences between the differing outcomes. A
considerable part of Grice’s rational choice theory is concerned with
formalizations of conditions of rationality and investigation of their
implications. When they are complete and transitive and satisfy a further
continuity condition, the agent’s preferences can be represented by an ordinal
utility function, i. e. it is then possible to define a function that
represents an agent’s preferences so that U(X)
> U(Y) iff if the agent prefers X to Y,
and U(X) = U(Y) iff if the agent
is indifferent between X and Y. This function represents
the preference ranking, and contains no information beyond the ranking. When in
addition they satisfy the independence condition, the agent’s preferences can
be represented by an expected utility function (Ramsey 1926). Such a function
has two important properties. First, the expected utility of a lottery is equal
to the sum of the expected utilities of its prizes weighted by their
probabilities. Second, expected utility functions are unique up to a positive
affine transformation. If U and V are
both expected utility functions representing the preferences of an agent, for
all objects of preference, X, V(X) must be
equal to aU(X) + b, where a and b are
real numbers and a is positive. The axioms of rationality
imply that the agent’s degrees of belief will satisfy the axioms of the
probability calculus. A great deal of controversy surrounds Grice’s theory of
rationality, and there have been many formal investigations into amendeding it.
Although a conversational pair is very different from this agent and this other
agent, the pair has a mechanism to evaluate alternatives and make a choice. The
evaluation and the choice may be rational or irrational. Pace Grice’s fruitful
seminars on rational helpfulness in cooperation, t is not, however, obvious,
what principles of rationality should govern the choices and evaluations of the
conversational dyad. Transitivity is one plausible condition. It seems that a
conversational dyad that chooses X when faced with the
alternatives X or Y, Y when
faced with the alternatives Y or Z and Z when
faced with the alternatives X or Z, the
conversational dyad has had “a change of hearts” or is choosing ‘irrationally.’
Yet, purported irrationalities such as these can easily arise from a standard
mechanism that aims to link a ‘conversational choice’ and individual
preferences. Suppose there are two conversationalists in the dyad. Individual
One ranks the alternatives X, Y, Z.
Individual Two ranks them Y, Z, X. (An
Individual Three if he comes by, may ranks them Z, X, Y).
If decisions are made by pairwise majority voting, X will be
chosen from the pair (X, Y), Y will
be chosen from (Y, Z), and Z will be
chosen from (X, Z). Clearly this is unsettling. But is a
possible cycle in a ‘conversational choice’ “irrational”? Similar
problems affect what one might call the logical coherence of a conversational
judgment Suppose the dyad consists of two individuals who make the following
judgments concerning the truth or falsity of the propositions P and Q and
that “conversational” judgment follows the majority. P if P, Q Q
Conversationalist A true
true true Conversationalist B false true false (Conversationalist C, if he
passes by) true false
false “Conversation” as an Institution: true true false. The judgment of each
conversationalist is consistent with the principles of logic, while the
“conversational co-operative” judgment violates the principles of logic. The
“cooperative conversational,” “altruistic,” “joint judgment” need not be
consistent with the principles of egoist logic. Although conversational choice
theory bears on questions of conversational rationality, most work in conversational
choice theory explores the consequences of principles of rationality coupled
with this or that explicitly practical, or meta-ethical constraint.
Grice does not use ‘moral,’ since he distinguishes what he calls a
‘conversational maxim’ from a ‘moral maxim’ of the type Kant universalizes. Arrow’s
impossibility theorem assumes that an individual preference and a concerted,
joint preference are complete and transitive and that the method of forming a
conversational, concerted, joint preference (or making a conversational,
concerted, choice) issues in some joint preference ranking or joint choice for
any possible profile (or dossier, as Grice prefers) of each individual
preference. Arrow’s impossibility theorem imposes a weak UNANIMITY (one-soul)
condition. If A and B prefers X to Y, Y must
not jointly preferred. Arrow’s impossibility theorem requires that there be no
boss (call him Immanuel, the Genitor) whose preference determines a joint
preference or choice irrespective of the preferences of anybody else. Arrow’s
impossibility theorem imposes the condition that the joint concerted
conversational preference between X and Y should
depend on how A and B rank X and Y and on
nothing else. Arrow’s impossibility theorem proves that no method of co-relating
or linking conversational and a monogogic preference can satisfy all these
conditions. If an monopreference and a mono-evaluations both satisfy the axioms
of expected utility theory (with shared or objective probabilities) and that a
duo-preference conform to the unanimous mono-preference, a duo- evaluation is
determined by a weighted sum of individual utilities. A form of weighted futilitarianism,
which prioritizes the interests of the recipient, rather than the emissor,
uniquely satisfies a longer list of rational and practical constraints. When
there are instead disagreements in probability assignments, there is an
impossibility result. The unanimity (‘one-soul’) condition implies that for
some profiles of individual preferences, a joint or duo-evaluation will not
satisfy the axioms of expected utility theory. When outcomes depend on what at
least two autonomous free agents do, one agent’s best choice may depend on what
the other agent chooses. Although the principles of rationality governing
mono-choice still apply, there is a further principle of conversational rationality
governing the ‘expectation’ (to use Grice’s favourite term) of the action (or
conversational move) of one’s co-conversationalist (and obviously, via the
mutuality requirement of applicational universalizability) of the
co-conversationalist’s ‘expectation’ concerning the conversationalist’s action
and expectation, and so forth. Grice’s Conversational Game Theory plays a
protagonist role within philosophy, and it is relevant to inquiries concerning conversational
rationality and inquiries concerning conversational ethics. Rational choice --
Probability -- Dutch book, a bet or combination of bets whereby the bettor is
bound to suffer a net loss regardless of the outcome. A simple example would be
a bet on a proposition p at odds of 3 : 2 combined with a bet on not-p at the
same odds, the total amount of money at stake in each bet being five dollars.
Under this arrangement, if p turned out to be true one would win two dollars by
the first bet but lose three dollars by the second, and if p turned out to be
false one would win two dollars by the second bet but lose three dollars by the
first. Hence, whatever happened, one would lose a dollar. Dutch book argument, the argument that a
rational person’s degrees of belief must conform to the axioms of the
probability calculus, since otherwise, by the Dutch book theorem, he would be
vulnerable to a Dutch book. R.Ke. Dutch book theorem, the proposition that
anyone who a counts a bet on a proposition p as fair if the odds correspond to
his degree of belief that p is true and who b is willing to make any
combination of bets he would regard individually as fair will be vulnerable to
a Dutch book provided his degrees of belief do not conform to the axioms of the
probability calculus. Thus, anyone of whom a and b are true and whose degree of
belief in a disjunction of two incompatible propositions is not equal to the
sum of his degrees of belief in the two propositions taken individually would
be vulnerable to a Dutch book.
rational
decision theory -- decidability, as a property of sets,
the existence of an effective procedure a “decision procedure” which, when
applied to any object, determines whether or not the object belongs to the set.
A theory or logic is decidable if and only if the set of its theorems is.
Decidability is proved by describing a decision procedure and showing that it
works. The truth table method, for example, establishes that classical
propositional logic is decidable. To prove that something is not decidable
requires a more precise characterization of the notion of effective procedure.
Using one such characterization for which there is ample evidence, Church
proved that classical predicate logic is not decidable. decision theory, the theory
of rational decision, often called “rational choice theory” in political
science and other social sciences. The basic idea probably Pascal’s was
published at the end of Arnaud’s Port-Royal Logic 1662: “To judge what one must
do to obtain a good or avoid an evil one must consider not only the good and
the evil in itself but also the probability of its happening or not happening,
and view geometrically the proportion that all these things have together.”
Where goods and evils are monetary, Daniel Bernoulli 1738 spelled the idea out
in terms of expected utilities as figures of merit for actions, holding that
“in the absence of the unusual, the utility resulting from a fixed small
increase in wealth will be inversely proportional to the quantity of goods previously
possessed.” This was meant to solve the St. Petersburg paradox: Peter tosses a
coin . . . until it should land “heads” [on toss n]. . . . He agrees to give
Paul one ducat if he gets “heads” on the very first throw [and] with each
additional throw the number of ducats he must pay is doubled. . . . Although
the standard calculation shows that the value of Paul’s expectation [of gain]
is infinitely great [i.e., the sum of all possible gains $ probabilities, 2n/2
$ ½n], it has . . . to be admitted that any fairly reasonable man would sell
his chance, with great pleasure, for twenty ducats. In this case Paul’s
expectation of utility is indeed finite on Bernoulli’s assumption of inverse
proportionality; but as Karl Menger observed 4, Bernoulli’s solution fails if
payoffs are so large that utilities are inversely proportional to
probabilities; then only boundedness of utility scales resolves the paradox.
Bernoulli’s idea of diminishing marginal utility of wealth survived in the
neoclassical texts of W. S. Jevons 1871, Alfred Marshall 0, and A. C. Pigou 0,
where personal utility judgment was understood to cause preference. But in the
0s, operationalistic arguments of John Hicks and R. G. D. Allen persuaded
economists that on the contrary, 1 utility is no cause but a description, in
which 2 the numbers indicate preference order but not intensity. In their
Theory of Games and Economic Behavior 6, John von Neumann and Oskar Morgenstern
undid 2 by pushing 1 further: ordinal preferences among risky prospects were now
seen to be describable on “interval” scales of subjective utility like the
Fahrenheit and Celsius scales for temperature, so that once utilities, e.g., 0
and 1, are assigned to any prospect and any preferred one, utilities of all
prospects are determined by overall preferences among gambles, i.e.,
probability distributions over prospects. Thus, the utility midpoint between
two prospects is marked by the distribution assigning probability ½ to each. In
fact, Ramsey had done that and more in a little-noticed essay “Truth and
Probability,” 1 teasing subjective probabilities as well as utilities out of
ordinal preferences among gambles. In a form independently invented by L. J.
Savage Foundations of Statistics, 4, this approach is now widely accepted as a
basis for rational decision analysis. The 8 book of that title by Howard Raiffa
became a theoretical centerpiece of M.B.A. curricula, whose graduates diffused
it through industry, government, and the military in a simplified format for
defensible decision making, namely, “costbenefit analyses,” substituting
expected numbers of dollars, deaths, etc., for preference-based expected
utilities. Social choice and group decision form the native ground of
interpersonal comparison of personal utilities. Thus, John C. Harsanyi 5 proved
that if 1 individual and social preferences all satisfy the von
Neumann-Morgenstern axioms, and 2 society is indifferent between two prospects
whenever all individuals are, and 3 society prefers one prospect to another
whenever someone does and nobody has the opposite preference, then social
utilities are expressible as sums of individual utilities on interval scales
obtained by stretching or compressing the individual scales by amounts
determined by the social preferences. Arguably, the theorem shows how to derive
interpersonal comparisons of individual preference intensities from social
preference orderings that are thought to treat individual preferences on a par.
Somewhat earlier, Kenneth Arrow had written that “interpersonal comparison of
utilities has no meaning and, in fact, there is no meaning relevant to welfare
economics in the measurability of individual utility” Social Choice and
Individual Values, 1 a position later
abandoned P. Laslett and W. G. Runciman, eds., Philosophy, Politics and
Society, 7. Arrow’s “impossibility theorem” is illustrated by cyclic
preferences observed by Condorcet in 1785 among candidates A, B, C of voters 1,
2, 3, who rank them ABC, BCA, CAB, respectively, in decreasing order of
preference, so that majority rule yields intransitive preferences for the group
of three, of whom two 1, 3 prefer A to B and two 1, 2 prefer B to C but two 2,
3 prefer C to A. In general, the theorem denies existence of technically
democratic schemes for forming social preferences from citizens’ preferences. A
clause tendentiously called “independence of irrelevant alternatives” in the
definition of ‘democratic’ rules out appeal to preferences among non-candidates
as a way to form social preferences among candidates, thus ruling out the
preferences among gambles used in Harsanyi’s theorem. See John Broome, Weighing
Goods, 1, for further information and references. Savage derived the agent’s
probabilities for states as well as utilities for consequences from preferences
among abstract acts, represented by deterministic assignments of consequences
to states. An act’s place in the preference ordering is then reflected by its
expected utility, a probability-weighted average of the utilities of its
consequences in the various states. Savage’s states and consequences formed
distinct sets, with every assignment of consequences to states constituting an
act. While Ramsey had also taken acts to be functions from states to
consequences, he took consequences to be propositions sets of states, and assigned
utilities to states, not consequences. A further step in that direction
represents acts, too, by propositions see Ethan Bolker, Functions Resembling
Quotients of Measures, Microfilms, 5;
and Richard Jeffrey, The Logic of Decision, 5, 0. Bolker’s representation
theorem states conditions under which preferences between truth of propositions
determine probabilities and utilities nearly enough to make the position of a
proposition in one’s preference ranking reflect its “desirability,” i.e., one’s
expectation of utility conditionally on it. decision theory decision theory
208 208 Alongside such basic properties
as transitivity and connexity, a workhorse among Savage’s assumptions was the
“sure-thing principle”: Preferences among acts having the same consequences in
certain states are unaffected by arbitrary changes in those consequences. This
implies that agents see states as probabilistically independent of acts, and
therefore implies that an act cannot be preferred to one that dominates it in
the sense that the dominant act’s consequences in each state have utilities at
least as great as the other’s. Unlike the sure thing principle, the principle
‘Choose so as to maximize CEU conditional expectation of utility’ rationalizes
action aiming to enhance probabilities of preferred states of nature, as in
quitting cigarettes to increase life expectancy. But as Nozick pointed out in
9, there are problems in which choiceworthiness goes by dominance rather than
CEU, as when the smoker like R. A. Fisher in 9 believes that the statistical
association between smoking and lung cancer is due to a genetic allele,
possessors of which are more likely than others to smoke and to contract lung
cancer, although among them smokers are not especially likely to contract lung
cancer. In such “Newcomb” problems choices are ineffectual signs of conditions
that agents would promote or prevent if they could. Causal decision theories
modify the CEU formula to obtain figures of merit distinguishing causal
efficacy from evidentiary significance
e.g., replacing conditional probabilities by probabilities of
counterfactual conditionals; or forming a weighted average of CEU’s under all
hypotheses about causes, with agents’ unconditional probabilities of hypotheses
as weights; etc. Mathematical statisticians leery of subjective probability
have cultivated Abraham Wald’s Theory of Statistical Decision Functions 0,
treating statistical estimation, experimental design, and hypothesis testing as
zero-sum “games against nature.” For an account of the opposite assimilation,
of game theory to probabilistic decision theory, see Skyrms, Dynamics of
Rational Deliberation 0. The “preference logics” of Sören Halldén, The Logic of
‘Better’ 7, and G. H. von Wright, The Logic of Preference 3, sidestep probability.
Thus, Halldén holds that when truth of p is preferred to truth of q, falsity of
q must be preferred to falsity of p, and von Wright with Aristotle holds that
“this is more choiceworthy than that if this is choiceworthy without that, but
that is not choiceworthy without this” Topics III, 118a. Both principles fail
in the absence of special probabilistic assumptions, e.g., equiprobability of p
with q. Received wisdom counts decision theory clearly false as a description
of human behavior, seeing its proper status as normative. But some, notably
Davidson, see the theory as constitutive of the very concept of preference, so
that, e.g., preferences can no more be intransitive than propositions can be at
once true and false. Rational decision:
envelope paradox, an apparent paradox in decision theory that runs as follows.
You are shown two envelopes, M and N, and are reliably informed that each
contains some finite positive amount of money, that the amount in one
unspecified envelope is twice the amount in the unspecified other, and that you
may choose only one. Call the amount in M ‘m’ and that in N ‘n’. It might seem
that: there is a half chance that m % 2n and a half chance that m = n/2, so
that the “expected value” of m is ½2n ! ½n/2 % 1.25n, so that you should prefer
envelope M. But by similar reasoning it might seem that the expected value of n
is 1.25m, so that you should prefer envelope N.
rationality – while Grice
never used to employ ‘rationality’ he learned to! In “Retrospective epilogue”
in fact he refers to the principle of conversational helpfulness as ‘promoting
conversational rationality.’ Rationality as a faculty psychology, the view that
the mind is a collection of departments responsible for distinct psychological
functions. Related to faculty psychology is the doctrine of localization of
function, wherein each faculty has a specific brain location. Faculty
psychologies oppose theories of mind as a unity with one function e.g., those
of Descartes and associationism or as a unity with various capabilities e.g.,
that of Ockham, and oppose the related holistic distributionist or mass-action
theory of the brain. Faculty psychology began with Aristotle, who divided the
human soul into five special senses, three inner senses common sense,
imagination, memory and active and passive mind. In the Middle Ages e.g.,
Aquinas Aristotle’s three inner senses were subdivied, creating more elaborate
lists of five to seven inward wits. Islamic physicianphilosophers such as Avicenna
integrated Aristotelian faculty psychology with Galenic medicine by proposing
brain locations for the faculties. Two important developments in faculty
psychology occurred during the eighteenth century. First, Scottish philosophers
led by Reid developed a version of faculty psychology opposed to the empiricist
and associationist psychologies of Locke and Hume. The Scots proposed that
humans were endowed by God with a set of faculties permitting knowledge of the
world and morality. The Scottish system exerted considerable influence in the
United States, where it was widely taught as a moral, character-building
discipline, and in the nineteenth century this “Old Psychology” opposed the
experimental “New Psychology.” Second, despite then being called a charlatan,
Franz Joseph Gall 17581828 laid the foundation for modern neuropsychology in
his work on localization of function. Gall rejected existing faculty
psychologies as philosophical, unbiological, and incapable of accounting for
everyday behavior. Gall proposed an innovative behavioral and biological list
of faculties and brain localizations based on comparative anatomy, behavior
study, and measurements of the human skull. Today, faculty psychology survives
in trait and instinct theories of personality, Fodor’s theory that mental
functions are implemented by neurologically “encapsulated” organs, and
localizationist theories of the brain.
rationalism, the position
that reason has precedence over other ways of acquiring knowledge, or, more
strongly, that it is the unique path to knowledge. It is most often encountered
as a view in epistemology, where it is traditionally contrasted with
empiricism, the view that the senses are primary with respect to knowledge. It
is important here to distinguish empiricism with respect to knowledge from
empiricism with respect to ideas or concepts; whereas the former is opposed to
rationalism, the latter is opposed to the doctrine of innate ideas. The term is
also encountered in the philosophy of religion, where it may designate those
who oppose the view that revelation is central to religious knowledge; and in
ethics, where it may designate those who oppose the view that ethical
principles are grounded in or derive from emotion, empathy, or some other
non-rational foundation. The term ‘rationalism’ does not generally designate a
single precise philosophical position; there are several ways in which reason
can have precedence, and several accounts of knowledge to which it may be
opposed. Furthermore, the very term ‘reason’ is not altogether clear. Often it
designates a faculty of the soul, distinct from sensation, imagination, and
memory, which is the ground of a priori knowledge. But there are other
conceptions of reason, such as the narrower conception in which Pascal opposes
reason to “knowledge of the heart” Pensées, section 110, or the computational
conception of reason Hobbes advances in Leviathan I.5. The term might thus be
applied to a number of philosophical positions from the ancients down to the
present. Among the ancients, ‘rationalism’ and ‘empiricism’ especially denote
two schools of medicine, the former relying primarily on a theoretical
knowledge of the hidden workings of the human body, the latter relying on
direct clinical experience. The term might also be used to characterize the
views of Plato and later Neoplatonists, who argued that we have pure
intellectual access to the Forms and general principles that govern reality,
and rejected sensory knowledge of the imperfect realization of those Forms in
the material world. In recent philosophical writing, the term ‘rationalism’ is
most closely associated with the positions of a group of seventeenth-century
philosophers, Descartes, Spinoza, Leibniz, and sometimes Malebranche. These
thinkers are often referred to collectively as the Continental rationalists,
and are generally opposed to the socalled British empiricists, Locke, Berkeley,
and Hume. All of the former share the view that we have a non-empirical and
rational access to the truth about the way the world is, and all privilege
reason over knowledge derived from the senses. These philosophers are also
attracted to mathematics as a model for knowledge in general. But these common
views are developed in quite different ways. Descartes claims to take his
inspiration from mathematics not
mathematics as commonly understood, but the analysis of the ancients. According
to Descartes, we start from first principles known directly by reason the
cogito ergo sum of the Meditations, what he calls intuition in his Rules for
the Direction of the Mind; all other knowledge is deduced from there. A central
aim of his Meditations is to show that this faculty of reason is trustworthy.
The senses, on the other hand, are generally deceptive, leading us to mistake
sensory qualities for real qualities of extended bodies, and leading us to the
false philosophy of Aristotle and to Scholasticism. Descartes does not reject
the senses altogether; in Meditation VI he argues that the senses are most
often correct in circumstances concerning the preservation of life. Perhaps
paradoxically, experiment is important to Descartes’s scientific work. However,
his primary interest is in the theoretical account of the phenomena experiment
reveals, and while his position is unclear, he may have considered experiment
as an auxiliary to intuition and deduction, or as a second-best method that can
be used with problems too complex for pure reason. Malebranche, following
Descartes, takes similar views in his Search after Truth, though unlike
Descartes, he emphasizes original sin as the cause of our tendency to trust the
senses. Spinoza’s model for knowledge is Euclidean geometry, as realized in the
geometrical form of the Ethics. Spinoza explicitly argues that we cannot have
adequate ideas of the world through sensation Ethics II, propositions 1631. In
the Ethics he does see a role for the senses in what he calls knowledge of the
first and knowledge of the second kinds, and in the earlier Emendation of the
Intellect, he suggests that the senses may be auxiliary aids to genuine
knowledge. But the senses are imperfect and far less valuable, according to
Spinoza, than intuition, i.e., knowledge of the third kind, from which sensory
experience is excluded. Spinoza’s rationalism is implicit in a central
proposition of the Ethics, in accordance with which “the order and connection
of ideas is the same as the order and connection of things” Ethics II,
proposition 7, allowing one to infer causal connections between bodies and
states of the material world directly from the logical connections between
ideas. Leibniz, too, emphasizes reason over the senses in a number of ways. In
his youth he believed that it would be possible to calculate the truth-value of
every sentence by constructing a logical language whose structure mirrors the
structure of relations between concepts in the world. This view is reflected in
his mature thought in the doctrine that in every truth, the concept of the
predicate is contained in the concept of the subject, so that if one could take
the God’s-eye view which, he concedes, we cannot, one could determine the truth
or falsity of any proposition without appeal to experience Discourse on
Metaphysics, section 8. Leibniz also argues that all truths are based on two
basic principles, the law of non-contradiction for necessary truths, and the
principle of sufficient reason for contingent truths Monadology, section 31,
both of which can be known a priori. And so, at least in principle, the
truth-values of all propositions can be determined a priori. This reflects his
practice in physics, where he derives a number of laws of motion from the
principle of the equality of cause and effect, which can be known a priori on
the basis of the principle of sufficient reason. But, at the same time,
referring to the empirical school of ancient medicine, Leibniz concedes that
“we are all mere Empirics in three fourths of our actions” Monadology, section
28. Each of the so-called Continental rationalists does, in his own way,
privilege reason over the senses. But the common designation ‘Continental
rationalism’ arose only much later, probably in the nineteenth century. For
their contemporaries, more impressed with their differences than their common
doctrines, the Continental rationalists did not form a single homogeneous
school of thought.
rationality. In its
primary sense, rationality is a normative concept that philosophers have
generally tried to characterize in such a way that, for any action, belief, or
desire, if it is rational we ought to choose it. No such positive characterization
has achieved anything close to universal assent because, often, several
competing actions, beliefs, or desires count as rational. Equating what is
rational with what is rationally required eliminates the category of what is
rationally allowed. Irrationality seems to be the more fundamental normative
category; for although there are conflicting substantive accounts of
irrationality, all agree that to say of an action, belief, or desire that it is
irrational is to claim that it should always be avoided. Rationality is also a
descriptive concept that refers to those intellectual capacities, usually
involving the ability to use language, that distinguish persons from plants and
most other animals. There is some dispute about whether some non-human animals,
e.g., dolphins and chimpanzees, are rational in this sense. Theoretical
rationality applies to beliefs. An irrational belief is one that obviously
conflicts with what one should know. This characterization of an irrational
belief is identical with the psychiatric characterization of a delusion. It is
a personrelative concept, because what obviously conflicts with what should be
known by one person need not obviously conflict with what should be known by
another. On this account, any belief that is not irrational counts as rational.
Many positive characterizations of rational beliefs have been proposed, e.g., 1
beliefs that are either self-evident or derived from self-evident beliefs by a
reliable procedure and 2 beliefs that are consistent with the overwhelming
majority of one’s beliefs; but all of these positive characterizations have
encountered serious objections. Practical rationality applies to actions. For
some philosophers it is identical to instrumental rationality. On this view,
commonly called instrumentalism, acting rationally simply means acting in a way
that is maximally efficient in achieving one’s goals. However, most
philosophers realize that achieving one goal may conflict with achieving
another, and therefore require that a rational action be one that best achieves
one’s goals only when these goals are considered as forming a system. Others
have added that all of these goals must be ones that would be chosen given
complete knowledge and understanding of what it would be like to achieve these
goals. On the latter account of rational action, the system of goals is chosen
by all persons for themselves, and apart from consistency there is no external
standpoint from which to evaluate rationally any such system. Thus, for a
person with a certain system of goals it will be irrational to act morally.
Another account of rational action is not at all person-relative. On this
account, to act rationally is to act on universalizable principles, so that
what is a reason for one person must be a reason for everyone. One point of
such an account is to make it rationally required to act morally, thus making
all immoral action irrational. However, if to call an action irrational is to
claim that everyone would hold that it is always to be avoided, then it is
neither irrational to act immorally in order to benefit oneself or one’s
friends, nor irrational to act morally even when that goes against one’s system
of goals. Only a negative characterization of what is rational as what is not
irrational, which makes it rationally permissible to act either morally or in
accordance with one’s own system of goals, as long as these goals meet some
minimal objective standard, seems likely to be adequate.
rationalization, 1 an
apparent explanation of a person’s action or attitude by appeal to reasons that
would justify or exculpate the person for it
if, contrary to fact, those reasons were to explain it; 2 an explanation
or interpretation made from a rational perspective. In sense 1,
rationalizations are pseudo-explanations, often motivated by a desire to
exhibit an item in a favorable light. Such rationalizations sometimes involve
self-deception. Depending on one’s view of justification, a rationalization
might justify an action by adducing
excellent reasons for its performance
even if the agent, not having acted for those reasons, deserves no
credit for so acting. In sense 2 a sense popularized in philosophy by Donald
Davidson, rationalizations of intentional actions are genuine explanations in
terms of agents’ reasons. In this sense, we provide a rationalization for or “rationalize” Robert’s shopping at Zed’s by identifying the
reasons for which he does so: e.g., he wants to buy an excellent kitchen knife
and believes that Zed’s sells the best cutlery in town. Also, the reasons for
which an agent acts may themselves be said to rationalize the action. Beliefs,
desires, and intentions may be similarly rationalized. In each case, a
rationalization exhibits the rationalized item as, to some degree, rational
from the standpoint of the person to whom it is attributed.
rational psychology, the
a priori study of the mind. This was a large component of eighteenthand
nineteenth-century psychology, and was contrasted by its exponents with
empirical psychology, which is rooted in contingent experience. The term
‘rational psychology’ may also designate a mind, or form of mind, having the
property of rationality. Current philosophy of mind includes much discussion of
rational psychologies, but the notion is apparently ambiguous. On one hand,
there is rationality as intelligibility. This is a minimal coherence, say of
desires or inferences, that a mind must possess to be a mind. For instance,
Donald Davidson, many functionalists, and some decision theorists believe there
are principles of rationality of this sort that constrain the appropriate
attribution of beliefs and desires to a person, so that a mind must meet such
constraints if it is to have beliefs and desires. On another pole, there is
rationality as justification. For someone’s psychology to have this property is
for that psychology to be as reason requires it to be, say for that person’s
inferences and desires to be supported by proper reasons given their proper
weight, and hence to be justified. Rationality as justification is a normative
property, which it would seem some minds lack. But despite the apparent
differences between these two sorts of rationality, some important work in
philosophy of mind implies either that these two senses in fact collapse, or at
least that there are intervening and significant senses, so that things at
least a lot like normative principles constrain what our psychologies are.
rational reconstruction,
also called logical reconstruction, translation of a discourse of a certain
conceptual type into a discourse of another conceptual type with the aim of
making it possible to say everything or everything important that is
expressible in the former more clearly or perspicuously in the latter. The
best-known example is one in Carnap’s Der Logische Aufbau der Welt. Carnap
attempted to translate discourse concerning physical objects e.g., ‘There is a
round brown table’ into discourse concerning immediate objects of sense
experience ‘Color patches of such-and-such chromatic characteristics and shape
appear in such-and-such a way’. He was motivated by the empiricist doctrine
that immediate sense experience is conceptually prior to everything else,
including our notion of a physical object. In addition to talk of immediate
sense experience, Carnap relied on logic and set theory. Since their use is
difficult to reconcile with strict empiricism, his translation would not have
fully vindicated empiricism even if it had succeeded.
Rationality -- reasons
for action, considerations that call for or justify action. They may be
subjective or objective. A subjective reason is a consideration an agent
understands to support a course of action, whether or not it actually does. An
objective reason is one that does support a course of action, regardless of
whether the agent realizes it. What are cited as reasons may be matters either
of fact or of value, but when facts are cited values are also relevant. Thus
the fact that cigarette smoke contains nicotine is a reason for not smoking
only because nicotine has undesirable effects. The most important evaluative
reasons are normative reasons i.e.,
considerations having e.g. ethical force. Facts become obligating reasons when,
in conjunction with normative considerations, they give rise to an obligation.
Thus in view of the obligation to help the needy, the fact that others are
hungry is an obligating reason to see they are fed. Reasons for action enter
practical thinking as the contents of beliefs, desires, and other mental
states. But not all the reasons one has need motivate the corresponding
behavior. Thus I may recognize an obligation to pay taxes, yet do so only for
fear of punishment. If so, then only my fear is an explaining reason for my
action. An overriding reason is one that takes precedence over all others. It is
often claimed that moral reasons override all others objectively, and should do
so subjectively as well. Finally, one may speak of an all-things-considered
reason one that after due consideration
is taken as finally determinative of what shall be done. reasons for belief, roughly, bases of belief.
The word ‘belief’ is commonly used to designate both a particular sort of
psychological state, a state of believing, and a particular intentional content
or proposition believed. Reasons for belief exhibit an analogous duality. A
proposition, p, might be said to provide a normative reason to believe a
proposition, q, for instance, when p bears some appropriate warranting relation
to q. And p might afford a perfectly good reason to believe q, even though no
one, as a matter of fact, believes either p or q. In contrast, p is a reason
that I have for believing q, if I believe p and p counts as a reason in the
sense above to believe q. Undoubtedly, I have reason to believe countless
propositions that I shall never, as it happens, come to believe. Suppose,
however, that p is a reason for which I believe q. In that case, I must believe
both p and q, and p must be a reason to believe q or, at any rate, I must regard it as such. It
may be that I must, in addition, believe q at least in part because I believe
p. Reasons in these senses are inevitably epistemic; they turn on
considerations of evidence, truth-conduciveness, and the like. But not all
reasons for belief are of this sort. An explanatory reason, a reason why I believe
p, may simply be an explanation for my having or coming to have this belief.
Perhaps I believe p because I was brainwashed, or struck on the head, or
because I have strong non-epistemic motives for this belief. I might, of
course, hold the belief on the basis of unexceptionable epistemic grounds. When
this is so, my believing p may both warrant and explain my believing q.
Reflections of this sort can lead to questions concerning the overall or
“all-things-considered” reasonableness of a given belief. Some philosophers
e.g., Clifford argue that a belief’s reasonableness depends exclusively on its
epistemic standing: my believing p is reasonable for me provided it is
epistemically reasonable for me; where belief is concerned, epistemic reasons
are overriding. Others, siding with James, have focused on the role of belief
in our psychological economy, arguing that the reasonableness of my holding a
given belief can be affected by a variety of non-epistemic considerations.
Suppose I have some evidence that p is false, but that I stand to benefit in a
significant way from coming to believe p. If that is so, and if the practical
advantages of my holding p considerably outweigh the practical disadvantages,
it might seem obvious that my holding p is reasonable for me in some
all-embracing sense.
Rawls, John b.1, philosopher widely recognized as one of the
leading political philosophers of the twentieth century. His A Theory of
Justice 1 is one of the primary texts in political philosophy. Political
Liberalism 3 revises Rawls’s theory to make his conception of justice
compatible with liberal pluralism, but leaves the core of his conception
intact. Drawing on the liberal and democratic social contract traditions of
Locke, Rousseau, and Kant, Rawls argues that the most reasonable principles of
justice are those everyone would accept and agree to from a fair position.
Since these principles determine the justice of society’s political
constitution, economy, and property rules its “basic structure”, Rawls takes a fair
agreement situation to be one where everyone is impartially situated as equals.
In this so-called original position everyone is equally situated by a
hypothetical “veil of ignorance.” This veil requires individuals to set aside
their knowledge of their particular differences, including knowledge of their
talents, wealth, social position, religious and philosophical views, and
particular conceptions of value. Rawls argues that in the hypothetical original
position everyone would reject utilitarianism, perfectionism, and intuitionist
views. Instead they would unanimously accept justice as fairness. This
conception of justice consists mainly of two principles. The first principle
says that certain liberties are basic and are to be equally provided to all: liberty
of conscience, freedom of thought, freedom of association, equal political
liberties, freedom and integrity of the person, and the liberties that maintain
the rule of law. These are basic liberties, because they are necessary to
exercise one’s “moral powers.” The two moral powers are, first, the capacity to
be rational, to have a rational conception of one’s good; and second, the
capacity for a sense of justice, to understand, apply, and act from
requirements of justice. These powers constitute essential interests of free
and equal moral persons since they enable each person to be a free and
responsible agent taking part in social cooperation. Rawls’s second principle
of justice, the difference principle, regulates permissible differences in
rights, powers, and privileges. It defines the limits of inequalities in
wealth, income, powers, and positions that may exist in a just society. It
says, first, that social positions are to be open to all to compete for on
terms of fair equality of opportunity. Second, inequalities in wealth, income,
and social powers and positions are permissible only if they maximally benefit
the least advantaged class in society. The difference principle implies that a
just economic system distributes income and wealth so as to make the class of
least advantaged persons better off than they would be under any alternative
economic system. This principle is to be consistent with the “priority” of the
first principle, which requires that equal basic liberties cannot be traded for
other benefits. The least advantaged’s right to vote, for example, cannot be
limited for the sake of improving their relative economic position. Instead, a
basic liberty can be limited only for the sake of maintaining other basic
liberties. Rawls contends that, taking the two principles of justice together,
a just society maximizes the worth to the least advantaged of the basic
liberties shared by all Theory, p. 205. The priority of basic liberty implies a
liberal egalitarian society in which each person is ensured adequate resources
to effectively exercise her basic liberties and become independent and
self-governing. A just society is then governed by a liberal-democratic
constitution that protects the basic liberties and provides citizens with
equally effective rights to participate in electoral processes and influence
legislation. Economically a just society incorporates a modified market system
that extensively distributes income and wealth
either a “property-owning democracy” with widespread ownership of means
of production, or liberal socialism.
Ray, J. English
naturalist whose work on the structure and habits of plants and animals led to
important conclusions on the methodology of classification and gave a strong
impetus to the design argument in natural theology. In an early paper he argued
that the determining characteristics of a species are those transmitted by
seed, since color, scent, size, etc., vary with climate and nutriment.
Parallels from the animal kingdom suggested the correct basis for classification
would be structural. But we have no knowledge of real essences. Our experience
of nature is of a continuum, and for practical purposes kinships are best
identified by a plurality of criteria. His mature theory is set out in
Dissertatio Brevis 1696 and Methodus Emendata 1703. The Wisdom of God
Manifested in the Works of the Creation 1691 and three revisions was a
best-selling compendium of Ray’s own scientific learning and was imitated and
quarried by many later exponents of the design argument. Philosophically, he
relied on others, from Cicero to Cudworth, and was superseded by Paley.
Realism – causal realism
-- direct realism, the theory that perceiving is epistemically direct,
unmediated by conscious or unconscious inference. Direct realism is distinguished,
on the one hand, from indirect, or representative, realism, the view that
perceptual awareness of material objects is mediated by an awareness of sensory
representations, and, on the other hand, from forms of phenomenalism that
identify material objects with states of mind. It might be thought that direct
realism is incompatible with causal theories of perception. Such theories
invoke causal chains leading from objects perceived causes to perceptual states
of perceivers effects. Since effects must be distinct from causes, the relation
between an instance of perceiving and an object perceived, it would seem,
cannot be direct. This, however, confuses epistemic directness with causal
directness. A direct realist need only be committed to the former. In
perceiving a tomato to be red, the content of my perceptual awareness is the
tomato’s being red. I enter this state as a result of a complex causal process,
perhaps. But my perception may be direct in the sense that it is unmediated by
an awareness of a representational sensory state from which I am led to an
awareness of the tomato. Perceptual error, and more particularly,
hallucinations and illusions, are usually thought to pose special difficulties
for direct realists. My hallucinating a red tomato, for instance, is not my
being directly aware of a red tomato, since I may hallucinate the tomato even
when none is present. Perhaps, then, my hallucinating a red tomato is partly a
matter of my being directly aware of a round, red sensory representation. And
if my awareness in this case is indistinguishable from my perception of an
actual red tomato, why not suppose that I am aware of a sensory representation
in the veridical case as well? A direct realist may respond by denying that
hallucinations are in fact indistinguishable from veridical perceivings or by
calling into question the claim that, if sensory representations are required
to explain hallucinations, they need be postulated in the veridical case. reality, in standard philosophical usage, how
things actually are, in contrast with their mere appearance. Appearance has to
do with how things seem to a particular perceiver or group of perceivers.
Reality is sometimes said to be twoway-independent of appearance. This means
that appearance does not determine reality. First, no matter how much agreement
there is, based on appearance, about the nature of reality, it is always
conceivable that reality differs from appearance. Secondly, appearances are in
no way required for reality: reality can outstrip the range of all
investigations that we are in a position to make. It may be that reality always
brings with it the possibility of appearances, in the counterfactual sense that
if there were observers suitably situated, then if conditions were not conducive
to error, they would have experiences of such-and-such a kind. But the truth of
such a counterfactual seems to be grounded in the facts of reality.
Phenomenalism holds, to the contrary, that the facts of reality can be
explained by such counterfactuals, but phenomenalists have failed to produce
adequate non-circular analyses. The concept of reality on which it is
two-wayindependent of experience is sometimes called objective reality.
However, Descartes used this phrase differently, to effect a contrast with
formal or actual reality. He held that there must be at least as much reality
in the efficient and total cause of an effect as in the effect itself, and
applied this principle as follows: “There must be at least as much actual or
formal reality in the efficient and total cause of an idea as objective reality
in the idea itself.” The objective reality of an idea seems to have to do with
its having representational content, while actual or formal reality has to do
with existence independent of the mind. Thus the quoted principle relates
features of the cause of an idea to the representational content of the idea.
Descartes’s main intended applications were to God and material objects.
recursive function
theory, a relatively recent area of mathematics that takes as its point of
departure the study of an extremely limited class of arithmetic functions
called the recursive functions. Strictly speaking, recursive function theory is
a branch of higher arithmetic number theory, or the theory of natural numbers whose
universe of discourse is restricted to the nonnegative integers: 0, 1, 2, etc.
However, the techniques and results of the newer area do not resemble those
traditionally associated with number theory. The class of recursive functions
is defined in a way that makes evident that every recursive function can be
computed or calculated. The hypothesis that every calculable function is
recursive, which is known as Church’s thesis, is often taken as a kind of axiom
in recursive function theory. This theory has played an important role in
modern philosophy of mathematics, especially when epistemological issues are
studied.
redintegration, a
psychological process, similar to or involving classical conditioning, in which
one feature of a situation causes a person to recall, visualize, or recompose
an entire original situation. On opening a pack of cigarettes, a person may
visualize the entire process, including striking the match, lighting the
cigarette, and puffing. Redintegration is used as a technique in behavior
therapy, e.g. when someone trying to refrain from smoking is exposed to
unpleasant odors and vivid pictures of lungs caked with cancer, and then
permitted to smoke. If the unpleasantness of the odors and visualization
outweighs the reinforcement of smoking, the person may resist smoking.
Philosophically, redintegration is of interest for two reasons. First, the
process may be critical in prudence. By bringing long-range consequences of
behavior into focus in present deliberation, redintegration may help to protect
long-range interests. Second, redintegration offers a role for visual images in
producing behavior. Images figure in paradigmatic cases of redintegration. In
recollecting pictures of cancerous lungs, the person may refrain from smoking.
reductionism: The issue of reductionism is very much
twentieth-century. There was Wisdom’s boring contribtions to Mind on ‘logical
construction,’ Grice read the summary from Broad. One of the twelve –isms that
Grice finds on his ascent to the City of Eternal Truth. He makes the reductive-reductionist
distinction. Against J. M. Rountree. So, for Grice, the bad heathen vicious
Reductionism can be defeated by the good Christian virtuous Reductivism. A
reductivist tries to define, say, what an emissor communicates (that p) in
terms of the content of that proposition that he intends to transmit to his
recipient. Following Aristotle, Grice reduces the effect to a ‘pathemata
psucheos,’ i. e. a passio of the anima, as Boethius translates. This can be
desiderative (“Thou shalt not kill”) or creditativa (“The grass is green.”)
reductio ad absurdum. 1
The principles A / - A / -A and -A / A / A. 2 The argument forms ‘If A then B
and not-B; therefore, not-A’ and ‘If not-A then B and not-B; therefore, A’ and
arguments of these forms. Reasoning via such arguments is known as the method
of indirect proof. 3 The rules of inference that permit i inferring not-A
having derived a contradiction from A and ii inferring A having derived a
contradiction from not-A. Both rules hold in classical logic and come to the
same thing in any logic with the law of double negation. In intuitionist logic,
however, i holds but ii does not.
reduction, the
replacement of one expression by a second expression that differs from the
first in prima facie reference. So-called reductions have been meant in the
sense of uniformly applicable explicit definitions, contextual definitions, or
replacements suitable only in a limited range of contexts. Thus, authors have
spoken of reductive conceptual analyses, especially in the early days of
analytic philosophy. In particular, in the sensedatum theory talk of physical
objects was supposed to be reduced to talk of sense-data by explicit
definitions or other forms of conceptual analysis. Logical positivists talked
of the reduction of theoretical vocabulary to an observational vocabulary,
first by explicit definitions, and later by other devices, such as Carnap’s
reduction sentences. These appealed to a test condition predicate, T e.g., ‘is
placed in water’, and a display predicate, D e.g., ‘dissolves’, to introduce a
dispositional or other “non-observational” term, S e.g., ‘is water-soluble’: Ex
[Tx / Dx / Sx], with ‘/’ representing the material conditional. Negative
reduction sentences for non-occurrence of S took the form Ex [NTx / NDx / -
Sx]. For coinciding predicate pairs T and TD and -D and ND Carnap referred to
bilateral reduction sentences: Ex [Tx / Dx S Sx]. Like so many other attempted
reductions, reduction sentences did not achieve replacement of the “reduced”
term, S, since they do not fix application of S when the test condition, T,
fails to apply. In the philosophy of mathematics, logicism claimed that all of
mathematics could be reduced to logic, i.e., all mathematical terms could be
defined with the vocabulary of logic and all theorems of mathematics could be
derived from the laws of logic supplemented by these definitions. Russell’s
Principia Mathematica carried out much of such a program with a reductive base
of something much more like what we now call set theory rather than logic,
strictly conceived. Many now accept the reducibility of mathematics to set
theory, but only in a sense in which reductions are not unique. For example,
the natural numbers can equally well be modeled as classes of equinumerous sets
or as von Neumann ordinals. This non-uniqueness creates serious difficulties,
with suggestions that set-theoretic reductions can throw light on what numbers
and other mathematical objects “really are.” In contrast, we take scientific
theories to tell us, unequivocally, that water is H20 and that temperature is
mean translational kinetic energy. Accounts of theory reduction in science
attempt to analyze the circumstance in which a “reducing theory” appears to
tell us the composition of objects or properties described by a “reduced
theory.” The simplest accounts follow the general pattern of reduction: one
provides “identity statements” or “bridge laws,” with at least the form of
explicit definitions, for all terms in the reduced theory not already appearing
in the reducing theory; and then one argues that the reduced theory can be
deduced from the reducing theory augmented by the definitions. For example, the
laws of thermodynamics are said to be deducible from those of statistical
mechanics, together with statements such as ‘temperature is mean translational
kinetic energy’ and ‘pressure is mean momentum transfer’. How should the
identity statements or bridge laws be understood? It takes empirical
investigation to confirm statements such as that temperature is mean
translational kinetic energy. Consequently, some have argued, such statements
at best constitute contingent correlations rather than strict identities. On
the other hand, if the relevant terms and their extensions are not mediated by
analytic definitions, the identity statements may be analogized to identities
involving two names, such as ‘Cicero is Tully’, where it takes empirical
investigation to establish that the two names happen to have the same referent.
One can generalize the idea of theory reduction in a variety of ways. One may
require the bridge laws to suffice for the deduction of the reduced from the
reducing theory without requiring that the bridge laws take the form of
explicit identity statements or biconditional correlations. Some authors have
also focused on the fact that in practice a reducing theory T2 corrects or
refines the reduced theory T1, so that it is really only a correction or
refinement, T1*, that is deducible from T2 and the bridge laws. Some have
consequently applied the term ‘reduction’ to any pair of theories where the
second corrects and extends the first in ways that explain both why the first
theory was as accurate as it was and why it made the errors that it did. In
this extended sense, relativity is said to reduce Newtonian mechanics. Do the
social sciences, especially psychology, in principle reduce to physics? This
prospect would support the so-called identity theory of mind and body, in
particular resolving important problems in the philosophy of mind, such as the
mindbody problem and the problem of other minds. Many though by no means all
are now skeptical about the prospects for identifying mental properties, and
the properties of other special sciences, with complex physical properties. To
illustrate with an example from economics adapted from Fodor, in the right
circumstances just about any physical object could count as a piece of money.
Thus prospects seem dim for finding a closed and finite statement of the form
‘being a piece of money is . . .’, with only predicates from physics appearing
on the right though some would want to admit infinite definitions in providing
reductions. Similarly, one suspects that attributes, such as pain, are at best
functional properties with indefinitely many possible physical realizations.
Believing that reductions by finitely stable definitions are thus out of reach,
many authors have tried to express the view that mental properties are still
somehow physical by saying that they nonetheless supervene on the physical
properties of the organisms that have them. In fact, these same difficulties
that affect mental properties affect the paradigm case of temperature, and
probably all putative examples of theoretical reduction. Temperature is mean
translational temperature only in gases, and only idealized ones at that. In
other substances, quite different physical mechanisms realize temperature.
Temperature is more accurately described as a functional property, having to do
with the mechanism of heat transfer between bodies, where, in principle, the
required mechanism could be physically realized in indefinitely many ways. In
most and quite possibly all cases of putative theory reduction by strict
identities, we have instead a relation of physical realization, constitution,
or instantiation, nicely illustrated by the property of being a calculator
example taken from Cummins. The property of being a calculator can be
physically realized by an abacus, by devices with gears and levers, by ones
with vacuum tubes or silicon chips, and, in the right circumstances, by
indefinitely many other physical arrangements. Perhaps many who have used
‘reduction’, particularly in the sciences, have intended the term in this sense
of physical realization rather than one of strict identity. Let us restrict
attention to properties that reduce in the sense of having a physical
realization, as in the cases of being a calculator, having a certain
temperature, and being a piece of money. Whether or not an object counts as
having properties such as these will depend, not only on the physical
properties of that object, but on various circumstances of the context.
Intensions of relevant language users constitute a plausible candidate for
relevant circumstances. In at least many cases, dependence on context arises
because the property constitutes a functional property, where the relevant
functional system calculational practices, heat transfer, monetary systems are
much larger than the propertybearing object in question. These examples raise
the question of whether many and perhaps all mental properties depend
ineliminably on relations to things outside the organisms that have the mental
properties.
reduction sentence, for a
given predicate Q3 of space-time points in a first-order language, any
universal sentence S1 of the form: x [Q1x / Q2x / Q3 x], provided that the
predicates Q1 and Q2 are consistently applicable to the same space-time points.
If S1 has the form given above and S2 is of the form x [Q4x / Q5 / - Q6] and
either S1 is a reduction sentence for Q3 or S2 is a reduction sentence for -Q3,
the pair {S1, S2} is a reduction pair for Q3. If Q1 % Q4 and Q2 % - Q5, the
conjunction of S1 and S2 is equivalent to a bilateral reduction sentence for Q3
of the form x [Q1 / Q3 S Q2]. These concepts were introduced by Carnap in
“Testability and Meaning,” Philosophy of Science 637, to modify the
verifiability criterion of meaning to a confirmability condition where terms
can be introduced into meaningful scientific discourse by chains of reduction
pairs rather than by definitions. The incentive for this modification seems to
have been to accommodate the use of disposition predicates in scientific
discourse. Carnap proposed explicating a disposition predicate Q3 by bilateral
reduction sentences for Q3. An important but controversial feature of Carnap’s
approach is that it avoids appeal to nonextensional conditionals in explicating
disposition predicates.
RELATUM -- referentially
transparent. An occurrence of a singular term t in a sentence ‘. . . t . . .’
is referentially transparent or purely referential if and only if the
truth-value of ‘. . . t . . .’ depends on whether the referent of t satisfies
the open sentence ‘. . . x . . .’; the satisfaction of ‘. . . x . . .’ by the
referent of t would guarantee the truth of ‘. . . t . . .’, and failure of this
individual to satisfy ‘. . . x . . .’ would guarantee that ‘. . . t . . .’ was
not true. ‘Boston is a city’ is true if and only if the referent of ‘Boston’
satisfies the open sentence ‘x is a city’, so the occurrence of ‘Boston’ is
referentially transparent. But in ‘The expression “Boston” has six letters’,
the length of the word within the quotes, not the features of the city Boston,
determines the truth-value of the sentence, so the occurrence is not referentially
transparent. According to a Fregean theory of meaning, the reference of any
complex expression that is a meaningful unit is a function of the referents of
its parts. Within this context, an occurrence of a referential term t in a
meaningful expression ‘. . . t . . .’ is referentially transparent or purely
referential if and only if t contributes its referent to the reference of ‘. .
. t . . .’. The expression ‘the area around Boston’ refers to the particular
area it does because of the referent of ‘Boston’ and the reference or extension
of the function expressed by ‘the area around x’. An occurrence of a
referential term t in a meaningful expression ‘. . . t . . .’ is referentially
opaque if and only if it is not referentially transparent. Thus, if t has a
referentially opaque occurrence in a sentence ‘. . . t . . .’, then the
truth-value of ‘. . . t . . .’ depends on something reduction, phenomenological
referentially transparent 780 780
other than whether the referent of t satisfies ‘. . . x . . .’. Although these
definitions apply to occurrences of referential terms, the terms ‘referentially
opaque’ and ‘referentially transparent’ are used primarily to classify
linguistic contexts for terms as referentially opaque contexts. If t occurs
purely referentially in S but not in CS, then C is a referentially opaque context. But we
must qualify this: C is a referentially
opaque context for that occurrence of t in S. It would not follow without
further argument that C is a
referentially opaque context for other occurrences of terms in sentences that
could be placed into C . Contexts of quotation, propositional attitude, and
modality have been widely noted for their potential to produce referential
opacity. Consider: 1 John believes that the number of planets is less than
eight. 2 John believes that nine is less than eight. If 1 is true but 2 is not,
then either ‘the number of planets’ or ‘nine’ has an occurrence that is not
purely referential, because the sentences would differ in truth-value even
though the expressions are co-referential. But within the sentences: 3 The
number of planets is less than eight. 4 Nine is less than eight. the
expressions appear to have purely referential occurrence. In 3 and 4, the
truth-value of the sentence as a whole depends on whether the referent of ‘The
number of planets’ and ‘Nine’ satisfies ‘x is less than eight’. Because the
occurrences in 3 and 4 are purely referential but those in 1 and 2 are not, the
context ‘John believes that ’ is a
referentially opaque context for the relevant occurrence of at least one of the
two singular terms. Some argue that the occurrence of ‘nine’ in 2 is purely
referential because the truth-value of the sentence as a whole depends on
whether the referent, nine, satisfies the open sentence ‘John believes that x
is less than eight’. Saying so requires that we make sense of the concept of
satisfaction for such sentences belief sentences and others and that we show
that the concept of satisfaction applies in this way in the case at hand
sentence 2. There is controversy about whether these things can be done. In 1,
on the other hand, the truth-value is not determined by whether nine the
referent of ‘the number of planets’ satisfies the open sentence, so that
occurrence is not purely referential. Modal contexts raise similar questions. 5
Necessarily, nine is odd. 6 Necessarily, the number of planets is odd. If 5 is
true but 6 is not, then at least one of the expressions does not have a purely
referential occurrence, even though both appear to be purely referential in the
non-modal sentence that appears in the context ‘Necessarily, ———’. Thus the
context is referentially opaque for the occurrence of at least one of these
terms. On an alternative approach, genuinely singular terms always occur
referentially, and ‘the number of planets’ is not a genuinely singular term.
Russell’s theory of definite descriptions, e.g., provides an alternative
semantic analysis for sentences involving definite descriptions. This would
enable us to say that even simple sentences like 3 and 4 differ considerably in
syntactic and semantic structure, so that the similarity that suggests the
problem, the seemingly similar occurrences of co-referential terms, is merely
apparent.
Mise-en-abyme--
reflection principles, two varieties of internal statements related to
correctness in formal axiomatic systems. 1 Proof-theoretic reflection
principles are formulated for effectively presented systems S that contain a
modicum of elementary number theory sufficient to arithmetize their own syntactic
notions, as done by Kurt Gödel in his 1 work on incompleteness. Let ProvS x
express that x is the Gödel number of a statement provable in S, and let nA be
the number of A, for any statement A of S. The weakest reflection principle
considered for S is the collection RfnS of all statements of the form ProvS nA
P A, which express that if A is provable from S then A is true. The proposition
ConS expressing the consistency of S is a consequence of RfnS obtained by
taking A to be a disprovable statement. Thus, by Gödel’s second incompleteness
theorem, RfnS is stronger than S if S is consistent. Reflection principles are
used in the construction of ordinal logics as a systematic means of overcoming
incompleteness. 2 Set-theoretic reflection principles are formulated for
systems S of axiomatic set theory, such as ZF Zermelo-Fraenkel. In the simplest
form they express that any property A in the language of S that holds of the
universe of “all” sets, already holds of a portion of that universe coextensive
with some set x. This takes the form A P DxAx where in Ax all quantifiers of A
are relativized to x. In contrast to proof-theoretic reflection principles,
these may be established as theorems of ZF.
reflective equilibrium,
as usually conceived, a coherence method for justifying evaluative principles
and theories. The method was first described by Goodman, who proposed it be
used to justify deductive and inductive principles. According to Goodman Fact,
Fiction and Forecast, 5, a particular deductive inference is justified by its
conforming with deductive principles, but these principles are justified in
their turn by conforming with accepted deductive practice. The idea, then, is
that justified inferences and principles are those that emerge from a process
of mutual adjustment, with principles being revised when they sanction
inferences we cannot bring ourselves to accept, and particular inferences being
rejected when they conflict with rules we are unwilling to revise. Thus,
neither principles nor particular inferences are epistemically privileged. At
least in principle, everything is liable to revision. Rawls further articulated
the method of reflective equilibrium and applied it in ethics. According to
Rawls A Theory of Justice, 1, inquiry begins with considered moral judgments,
i.e., judgments about which we are confident and which are free from common
sources of error, e.g., ignorance of facts, insufficient reflection, or
emotional agitation. According to narrow reflective equilibrium, ethical
principles are justified by bringing them into coherence with our considered
moral judgments through a process of mutual adjustment. Rawls, however, pursues
a wide reflective equilibrium. Wide equilibrium is attained by proceeding to
consider alternatives to the moral conception accepted in narrow equilibrium,
along with philosophical arguments that might decide among these conceptions.
The principles and considered judgments accepted in narrow equilibrium are then
adjusted as seems appropriate. One way to conceive of wide reflective
equilibrium is as an effort to construct a coherent system of belief by a
process of mutual adjustment to considered moral judgments and moral principles
as in narrow equilibrium along with the background philosophical, social
scientific, and any other relevant beliefs that might figure in the arguments
for and against alternative moral conceptions, e.g., metaphysical views
regarding the nature of persons. As in Goodman’s original proposal, none of the
judgments, principles, or theories involved is privileged: all are open to
revision.
Griceian renaissance –
after J. L. Austin’s death -- Erasmus, D., philosopher who played an important
role in Renaissance humanism. Like his
forerunners Petrarch, Coluccio Salutati, Lorenzo Valla, Leonardo Bruni,
and others, Erasmus stressed within philosophy and theology the function of
philological precision, grammatical correctness, and rhetorical elegance. But
for Erasmus the virtues of bonae literarae which are cultivated by the study of
authors of Latin and Grecian antiquity must be decisively linked with Christian
spirituality. Erasmus has been called by Huizinga the first modern intellectual
because he tried to influence and reform the mentality of society by working
within the shadow of ecclesiastical and political leaders. He epistemology,
evolutionary Erasmus, Desiderius 278
278 became one of the first humanists to make efficient use of the then
new medium of printing. His writings embrace various forms, including diatribe,
oration, locution, comment, dialogue, and letter. After studying in Christian
schools and living for a time in the monastery of Steyn near Gouda in the
Netherlands, Erasmus worked for different patrons. He gained a post as
secretary to the bishop of Kamerijk, during which time he wrote his first
published book, the Adagia first edition 1500, a collection of annotated Latin
adages. Erasmus was an adviser to the Emperor Charles V, to whom he dedicated
his Institutio principii christiani 1516. After studies at the of Paris, where he attended lectures by the
humanist Faber Stapulensis, Erasmus was put in touch by his patron Lord
Mountjoy with the British humanists John Colet and Thomas More. Erasmus led a
restless life, residing in several European cities including London, Louvain, Basel,
Freiburg, Bologna, Turin where he was awarded a doctorate of theology in 1506,
and Rome. By using the means of modern philology, which led to the ideal of the
bonae literarae, Erasmus tried to reform the Christian-influenced mentality of
his times. Inspired by Valla’s Annotationes to the New Testament, he completed
a new Latin translation of the New Testament, edited the writings of the early
church fathers, especially St. Hieronymus, and wrote several commentaries on
psalms. He tried to regenerate the spirit of early Christianity by laying bare
its original sense against the background of scholastic interpretation. In his
view, the rituals of the existing church blocked the development of an
authentic Christian spirituality. Though Erasmus shared with Luther a critical
approach toward the existing church, he did not side with the Reformation. His
Diatribe de libero arbitrio 1524, in which he pleaded for the free will of man,
was answered by Luther’s De servo arbitrio. The historically most influential books
of Erasmus were Enchirion militis christiani 1503, in which he attacked
hirelings and soldiers; the Encomium moriae id est Laus stultitiae 1511, a
satire on modern life and the ecclesiastical pillars of society; and the
sketches of human life, the Colloquia first published in 1518, often enlarged
until 1553. In the small book Querela pacis 1517, he rejected the ideology of
justified wars propounded by Augustine and Aquinas. Against the madness of war
Erasmus appealed to the virtues of tolerance, friendliness, and gentleness. All
these virtues were for him the essence of Christianity.
regression analysis, a
part of statistical theory concerned with the analysis of data with the aim of
inferring a linear functional relationship between assumed independent
“regressor” variables and a dependent “response” variable. A typical example
involves the dependence of crop yield on the application of fertilizer. For the
most part, higher amounts of fertilizer are associated with higher yields. But
typically, if crop yield is plotted vertically on a graph with the horizontal
axis representing amount of fertilizer applied, the resulting points will not
fall in a straight line. This can be due either to random “stochastic”
fluctuations involving measurement errors, irreproducible conditions, or
physical indeterminism or to failure to take into account other relevant
independent variables such as amount of rainfall. In any case, from any
resulting “scatter diagram,” it is possible mathematically to infer a
“best-fitting” line. One method is, roughly, to find the line that minimizes
the average absolute distance between a line and the data points collected.
More commonly, the average of the squares of these distances is minimized this
is the “least squares” method. If more than one independent variable is
suspected, the theory of multiple regression, which takes into account multiple
regressors, can be applied: this can help to minimize an “error term” involved
in regression. Computers must be used for the complex computations typically
encountered. Care must be taken in connection with the possibility that a
lawlike, causal dependence is not really linear even approximately over all
ranges of the regressor variables e.g., in certain ranges of amounts of
application, more fertilizer is good for a plant, but too much is bad.
Reichenbach, Hans 13, G.
philosopher of science and a major leader of the movement known as logical
empiricism. Born in Hamburg, he studied engineering for a brief time, then
turned to mathematics, philosophy, and physics, which he pursued at the
universities of Berlin, Munich, and Göttingen. He took his doctorate in
philosophy at Erlangen 5 with a dissertation on mathematical and philosophical
aspects of probability, and a degree in mathematics and physics by state
examination at Göttingen 6. In 3, with Hitler’s rise to power, he fled to
Istanbul, then to the of California at
Los Angeles, where he remained until his death. Prior to his departure from G.y
he was professor of philosophy of science at the of Berlin, leader of the Berlin Group of
logical empiricists, and a close associate of Einstein. With Carnap he founded
Erkenntnis, the major journal of scientific philosophy before World War II.
After a short period early in his career as a follower of Kant, Reichenbach
rejected the synthetic a priori, chiefly because of considerations arising out
of Einstein’s general theory of relativity. He remained thereafter champion of
empiricism, adhering to a probabilistic version of the verifiability theory of
cognitive meaning. Never, however, did he embrace the logical positivism of the
Vienna Circle; indeed, he explicitly described his principal epistemological
work, Experience and Prediction 8, as his refutation of logical positivism. In
particular, his logical empiricism consisted in rejecting phenomenalism in
favor of physicalism; he rejected phenomenalism both in embracing scientific
realism and in insisting on a thoroughgoing probabilistic analysis of
scientific meaning and scientific knowledge. His main works span a wide range.
In Probability and Induction he advocated the frequency interpretation of
probability and offered a pragmatic justification of induction. In his
philosophy of space and time he defended conventionality of geometry and of
simultaneity. In foundations of quantum mechanics he adopted a three-valued
logic to deal with causal anomalies. He wrote major works on epistemology,
logic, laws of nature, counterfactuals, and modalities. At the time of his
death he had almost completed The Direction of Time, which was published
posthumously 6.
Reid, Thomas 171096,
Scottish philosopher, a defender of common sense and critic of the theory of
impressions and ideas articulated by Hume. Reid was born exactly one year
before Hume, in Strachan, Scotland. A bright lad, he went to Marischal in Aberdeen at the age of twelve, studying
there with Thomas Blackwell and George Turnbull. The latter apparently had
great influence on Reid. Turnbull contended that knowledge of the facts of
sense and introspection may not be overturned by reasoning and that volition is
the only active power known from experience. Turnbull defended common sense
under the cloak of Berkeley. Reid threw off that cloak with considerable
panache, but he took over the defense of common sense from Turnbull. Reid moved
to a position of regent and lecturer at King’s
in Aberdeen in 1751. There he formed, with John Gregory, the Aberdeen
Philosophical Society, which met fortnightly, often to discuss Hume. Reid
published his Inquiry into the Human Mind on the Principles of Common Sense in
1764, and, in the same year, succeeded Adam Smith in the chair of moral
philosophy at Old in Glasgow. After 1780
he no longer lectured but devoted himself to his later works, Essays on the
Intellectual Powers 1785 and Essays on the Active Powers 1788. He was highly
influential in Scotland and on the Continent in the eighteenth century and,
from time to time, in England and the United States thereafter. Reid thought
that one of his major contributions was the refutation of Hume’s theory of
impressions and ideas. Reid probably was convinced in his teens of the truth of
Berkeley’s doctrine that what the mind is immediately aware of is always some
idea, but his later study of Hume’s Treatise convinced him that, contrary to
Berkeley, it was impossible to reconcile this doctrine, the theory of ideas,
with common sense. Hume had rigorously developed the theory, Reid said, and
drew forth the conclusions. These, Reid averred, were absurd. They included the
denial of our knowledge of body and mind, and, even more strikingly, of our
conceptions of these things. The reason Reid thought that Hume’s theory of
ideas led to these conclusions was that for Hume, ideas were faded impressions
of sense, hence, sensations. No sensation is like a quality of a material
thing, let alone like the object that has the quality. Consider movement.
Movement is a quality of an object wherein the object changes from one place to
another, but the visual sensation that arises in us is not the change of place
of an object, it is an activity of mind. No two things could, in fact, be more
unalike. If what is before the mind is always some sensation, whether vivacious
or faded, we should never obtain the conception of something other than a
sensation. Hence, we could never even conceive of material objects and their
qualities. Even worse, we could not conceive of our own minds, for they are not
sensations either, and only sensations are immediately before the mind,
according to the theory of ideas. Finally, and even more absurdly, we could not
conceive of past sensations or anything that does not now exist. For all that
is immediately before the mind is sensations that exist presently. Thus, we
could not even conceive of qualities, bodies, minds, and things that do not now
exist. But this is absurd, since it is obvious that we do think of all these
things and even of things that have never existed. The solution, Reid
suggested, is to abandon the theory of ideas and seek a better one. Many have
thought Reid was unfair to Hume and misinterpreted him. Reid’s Inquiry was
presented to Hume by Dr. Blair in manuscript form, however, and in reply Hume
does not at all suggest that he has been misinterpreted or handled unfairly.
Whatever the merits of Reid’s criticism of Hume, it was the study of the
consequences of Hume’s philosophy that accounts for Reid’s central doctrine of
the human faculties and their first principles. Faculties are innate powers,
among them the powers of conception and conviction. Reid’s strategy in reply to
Hume is to build a nativist theory of conception on the failure of Hume’s
theory of ideas. Where the theory of ideas, the doctrine of impressions and
ideas, fails to account for our conception of something, of qualities, bodies,
minds, past things, nonexistent things, Reid hypothesizes that our conceptions
originate from a faculty of the mind, i.e., from an innate power of conception.
This line of argument reflects Reid’s respect for Hume, whom he calls the
greatest metaphysician of the age, because Hume drew forth the consequences of
a theory of conception, which we might call associationism, according to which
all our conceptions result from associating sensations. Where the
associationism of Hume failed, Reid hypothesized that conceptions arise from
innate powers of conception that manifest themselves in accordance with
original first principles of the mind. The resulting hypotheses were not
treated as a priori necessities but as empirical hypotheses. Reid notes,
therefore, that there are marks by which we can discern the operation of an
innate first principle, which include the early appearance of the operation,
its universality in mankind, and its irresistibility. The operations of the
mind that yield our conceptions of qualities, bodies, and minds all bear these
marks, Reid contends, and that warrants the conclusion that they manifest first
principles. It should be noted that Reid conjectured that nature would be
frugal in the implantation of innate powers, supplying us with no more than
necessary to produce the conceptions we manifest. Reid is, consequently, a
parsimonious empiricist in the development of his nativist psychology. Reid
developed his theory of perception in great detail and his development led,
surprisingly, to his articulation of non-Euclidean geometry. Indeed, while Kant
was erroneously postulating the a priori necessity of Euclidean space, Reid was
developing non-Euclidean geometry to account for the empirical features of
visual space. Reid’s theory of perception is an example of his empiricism. In
the Inquiry, he says that sensations, which are operations of the mind, and
impressions on the organs of sense, which are material, produce our conceptions
of primary and secondary qualities. Sensations produce our original conceptions
of secondary qualities as the causes of those sensations. They are signs that
suggest the existence of the qualities. A sensation of smell suggests the
existence of a quality in the object that causes the sensation, though the
character of the cause is otherwise unknown. Thus, our original conception of
secondary qualities is a relative conception of some unknown cause of a
sensation. Our conception of primary qualities differs not, as Locke suggested,
because of some resemblance between the sensation and the quality for, as
Berkeley noted, there is no resemblance between a sensation and quality, but
because our original conceptions of primary qualities are clear and distinct.
The sensation is a sign that suggests a definite conception of the primary
quality, e.g. a definite conception of the movement of the object, rather than
a mere conception of something, we know not what, that gives rise to the
sensation. These conceptions of qualities signified by sensations result from
the operations of principles of our natural constitution. These signs, which
suggest the conception of qualities, also suggest a conception of some object
that has them. This conception of the object is also relative, in that it is
simply a conception of a subject of the qualities. In the case of physical
qualities, the conception of the object is a conception of a material object.
Though sensations, which are activities of the mind, suggest the existence of
qualities, they are not the only signs of sense perception. Some impressions on
the organs of sense, the latter being material, also give rise to conceptions
of qualities, especially to our conception of visual figure, the seen shape of
the object. But Reid can discern no sensation of shape. There are, of course,
sensations of color, but he is convinced from the experience of those who have
cataracts and see color but not shape that the sensations of color are
insufficient to suggest our conceptions of visual figure. His detailed account
of vision and especially of the seeing of visual figure leads him to one of his
most brilliant moments. He asks what sort of data do we receive upon the eye
and answers that the data must be received at the round surface of the eyeball
and processed within. Thus, visual space is a projection in three dimensions of
the information received on the round surface of the eye, and the geometry of
this space is a non-Euclidean geometry of curved space. Reid goes on to derive
the properties of the space quite correctly, e.g., in concluding that the
angles of a triangle will sum to a figure greater than 180 degrees and thereby
violate the parallels postulate. Thus Reid discovered that a non-Euclidean
geometry was satisfiable and, indeed, insisted that it accurately described the
space of vision not, however, the space of touch, which he thought was
Euclidean. From the standpoint of his theory of perceptual signs, the example
of visual figure helps to clarify his doctrine of the signs of perception. We
do not perceive signs and infer what they signify. This inference, Reid was
convinced by Hume, would lack the support of reasoning, and Reid concluded that
reasoning was, in this case, superfluous. The information received on the
surface of the eye produces our conceptions of visual figure immediately.
Indeed, these signs pass unnoticed as they give rise to the conception of
visual figure in the mind. The relation of sensory signs to the external things
they signify originally is effected by a first principle of the mind without
the use of reason. The first principles that yield our conceptions of qualities
and objects yield convictions of the existence of these things at the same
time. A question naturally arises as to the evidence of these convictions.
First principles yield the convictions along with the conceptions, but do we
have evidence of the existence of the qualities and objects we are convinced
exist? We have the evidence of our senses, of our natural faculties, and that
is all the evidence possible here. Reid’s point is that the convictions in
questions resulting from the original principles of our faculties are
immediately justified. Our faculties are, however, all fallible, so the
justification that our original convictions possess may be refuted. We can now
better understand Reid’s reply to Hume. To account for our convictions of the
existence of body, we must abandon Hume’s theory of ideas, which cannot supply
even the conception of body. We must discover both the original first
principles that yield the conception and conviction of objects and their
qualities, and first principles to account for our convictions of the past, of
other thinking beings, and of morals. Just as there are first principles of
perception that yield convictions of the existence of presently existing
objects, so there are first principles of memory that yield the convictions of
the existence of past things, principles of testimony that yield the
convictions of the thoughts of others, and principles of morals that yield
convictions of our obligations. Reid’s defense of a moral faculty alongside the
faculties of perception and memory is striking. The moral faculty yields
conceptions of the justice and injustice of an action in response to our
conception of that action. Reid shrewdly notes that different people may
conceive of the same action in different ways. I may conceive of giving some
money as an action of gratitude, while you may consider it squandering money.
How we conceive of an action depends on our moral education, but the response
of our moral faculty to an action conceived in a specific way is original and
the same in all who have the faculty. Hence differences in moral judgment are
due, not to principles of the moral faculty, but to differences in how we
conceive of our actions. This doctrine of a moral faculty again provides a counterpoint
to the moral philosophy of Hume, for, according Reid, Thomas Reid, Thomas
785 785 to Reid, judgments of justice
and injustice pertaining to all matters, including promises, contracts, and
property, arise from our natural faculties and do not depend on anything
artificial. Reid’s strategy for defending common sense is clear enough. He
thinks that Hume showed that we cannot arrive at our convictions of external
objects, of past events, of the thoughts of others, of morals, or, for that
matter, of our own minds, from reasoning about impressions and ideas. Since
those convictions are a fact, philosophy must account for them in the only way
that remains, by the hypothesis of innate faculties that yield them. But do we
have any evidence for these convictions? Evidence, Reid says, is the ground of
belief, and our evidence is that of our faculties. Might our faculties deceive
us? Reid answers that it is a first principle of our faculties that they are
not fallacious. Why should we assume that our faculties are not fallacious?
First, the belief is irresistible. However we wage war with first principles,
the principles of common sense, they prevail in daily life. There we trust our
faculties whether we choose to or not. Second, all philosophy depends on the
assumption that our faculties are not fallacious. Here Reid employs an ad
hominem argument against Hume, but one with philosophical force. Reid says
that, in response to a total skeptic who decides to trust none of his
faculties, he puts his hand over his mouth in silence. But Hume trusted reason
and consciousness, and therefore is guilty of pragmatic inconsistency in
calling the other faculties into doubt. They come from the same shop, Reid
says, and he who calls one into doubt has no right to trust the others. All our
faculties are fallible, and, therefore, we must, to avoid arbitrary favoritism,
trust them all at the outset or trust none. The first principles of our
faculties are trustworthy. They not only account for our convictions, but are
the ground and evidence of those convictions. This nativism is the original
engine of justification. Reid’s theory of original perceptions is supplemented
by a theory of acquired perceptions, those which incorporate the effects of
habit and association, such as the perception of a passing coach. He
distinguishes acquired perceptions from effects of reasoning. The most
important way our original perceptions must be supplemented is by general
conceptions. These result from a process whereby our attention is directed to
some individual quality, e.g., the whiteness of a piece of paper, which he
calls abstraction, and a further process of generalizing from the individual
quality to the general conception of the universal whiteness shared by many
individuals. Reid is a sophisticated nominalist; he says that the only things
that exist are individual, but he includes individual qualities as well as
individual objects. The reason is that individual qualities obviously exist and
are needed as the basis of generalization. To generalize from an individual we
must have some conception of what it is like, and this conception cannot be
general, on pain of circularity or regress, but must be a conception of an
individual quality, e.g., the whiteness of this paper, which it uniquely possesses.
Universals, though predicated of objects to articulate our knowledge, do not
exist. We can think of universals, just as we can think of centaurs, but though
they are the objects of thought and predicated of individuals that exist, they
do not themselves exist. Generalization is not driven by ontology but by
utility. It is we and not nature that sort things into kinds in ways that are
useful to us. This leads to a division-of-labor theory of meaning because
general conceptions are the meanings of general words. Thus, in those domains
in which there are experts, in science or the law, we defer to the experts
concerning the general conceptions that are the most useful in the area in
question. Reid’s theory of the intellectual powers, summarized briefly above,
is supplemented by his theory of our active powers, those that lead to actions.
His theory of the active powers includes a theory of the principles of actions.
These include animal principles that operate without understanding, but the
most salient and philosophically important part of Reid’s theory of the active
powers is his theory of the rational principles of action, which involve
understanding and the will. These rational principles are those in which we
have a conception of the action to be performed and will its performance.
Action thus involves an act of will or volition, but volitions as Reid
conceived of them are not the esoteric inventions of philosophy but, instead,
the commonplace activities of deciding and resolving to act. Reid is a libertarian
and maintains that our liberty or freedom refutes the principle of necessity or
determinism. Freedom requires the power to will the action and also the power
not to will it. The principle of necessity tells us that our action was
necessitated and, therefore, that it was not in our power not to have willed as
we did. It is not sufficient for freedom, as Hume suggested, that we act as we
will. We must also have the Reid, Thomas Reid, Thomas 786 786 power to determine what we will. The
reason is that willing is the means to the end of action, and he who lacks
power over the means lacks power over the end. This doctrine of the active
power over the determinations of our will is founded on the central principle
of Reid’s theory of the active powers, the principle of agent causation. The
doctrine of acts of the will or volitions does not lead to a regress, as
critics allege, because my act of will is an exercise of the most basic kind of
causality, the efficient causality of an agent. I am the efficient cause of my
acts of will. My act of will need not be caused by an antecedent act of will
because my act of will is the result of my exercise of my causal power. This
fact also refutes an objection to the doctrine of liberty that if my action is not necessitated, then
it is fortuitous. My free actions are caused, not fortuitous, though they are
not necessitated, because they are caused by me. How, one might inquire, do we
know that we are free? The doubt that we are free is like other skeptical
doubts, and receives a similar reply, namely, that the conviction of our
freedom is a natural and original conviction arising from our faculties. It
occurs prior to instruction and it is irresistible in practical life. Any
person with two identical coins usable to pay for some item must be convinced
that she can pay with the one or the other; and, unlike the ass of Buridan, she
readily exercises her power to will the one or the other. The conviction of
freedom is an original one, not the invention of philosophy, and it arises from
the first principles of our natural faculties, which are trustworthy and not
fallacious. The first principles of our faculties hang together like links in a
chain, and one must either raise up the whole or the links prove useless.
Together, they are the foundation of true philosophy, science, and practical
life, and without them we shall lead ourselves into the coalpit of skepticism
and despair.
Reimarus, Hermann Samuel
16941768, G. philosopher, born in Hamburg and educated in philosophy and
theology at Jena. For most of his life he taught Oriental languages at a high
school in Hamburg. The most important writings he published were a treatise on
natural religion, Abhandlungen von den vornehmsten Wahrheiten der natürlichen
Religion 1754; a textbook on logic, Vernunftlehre 1756; and an interesting work
on instincts in animals, Allgemeine Betrachtungen über die Triebe der Tiere
1760. However, he is today best known for his Apologie oder Schutzschrift für
die vernünftigen Verehrer Gottes “Apology for or Defense of the Rational
Worshipers of God”, posthumously published in 177477. In it, Reimarus reversed
his stance on natural theology and openly advocated a deism in the British
tradition. The controversy created by its publication had a profound impact on
the further development of G. theology. Though Reimarus always remained
basically a follower of Wolff, he was often quite critical of Wolffian
rationalism in his discussion of logic and psychology.
Reinhold, Karl Leonhard
17431819, Austrian philosopher who was both a popularizer and a critic of Kant.
He was the first occupant of the chair of critical philosophy established at
the of Jena in 1787. His Briefe über die
Kantische Philosophie 1786/87 helped to popularize Kantianism. Reinhold also
proclaimed the need for a more “scientific” presentation of the critical
philosophy, in the form of a rigorously deductive system in which everything is
derivable from a single first principle “the principle of consciousness”. He
tried to satisfy this need with Elementarphilosophie “Elementary Philosophy” or
“Philosophy of the Elements”, expounded in his Versuch einer neuen Theorie des
menschlichen Vorstellungsvermögens “Attempt at a New Theory of the Human
Faculty of Representation,” 1789, Beyträge zur Berichtigung bisheriger
Missverständnisse der Philosophen I “Contributions to the Correction of the
Prevailing Misunderstandings of Philosophers,” 1790, and Ueber das Fundament
des philosophischen Wissens “On the Foundation of Philosophical Knowledge,”
1791. His criticism of the duality of Kant’s starting point and of the ad hoc
character of his deductions contributed to the demand for a more coherent
exposition of transcendental idealism, while his strategy for accomplishing
this task stimulated others above all, Fichte to seek an even more
“fundamental” first principle for philosophy. Reinhold later became an
enthusiastic adherent, first of Fichte’s Wissenschaftslehre and then of
Bardili’s “rational realism,” before finally adopting a novel “linguistic”
approach to philosophical problems.
reism, also called
concretism, the theory that the basic entities are concrete objects. Reism
differs from nominalism in that the problem of universals is not its only
motivation and often not the principal motivation for the theory. Three types
of reism can be distinguished. 1 Brentano held that every object is a concrete
or individual thing. He said that substances, aggregates of substances, parts
of substances, and individual properties of substances are the only things that
exist. There is no such thing as the existence or being of an object; and there
are no non-existent objects. One consequence of this doctrine is that the
object of thought what the thought is about is always an individual object and
not a proposition. For example, the thought that this paper is white is about
this paper and not about the proposition that this paper is white. Meinong
attacked Brentano’s concretism and argued that thoughts are about “objectives,”
not objects. 2 Kotarbigski, who coined the term ‘reism’, holds as a basic
principle that only concrete objects exist. Although things may be hard or
soft, red or blue, there is no such thing as hardness, softness, redness, or
blueness. Sentences that contain abstract words are either strictly meaningless
or can be paraphrased into sentences that do not contain any abstract words.
Kotarbinski is both a nominalist and a materialist. Brentano was a nominalist
and a dualist. 3 Thomas Garrigue Masaryk’s concretism is quite different from
the first two. For him, concretism is the theory that all of a person’s
cognitive faculties participate in every instance of knowing: reason, senses,
emotion, and will.
relation, a
two-or-more-place property e.g., loves or between, or the extension of such a
property. In set theory, a relation is any set of ordered pairs or triplets,
etc., but these are reducible to pairs. For simplicity, the formal exposition
here uses the language of set theory, although an intensional
property-theoretic view is later assumed. The terms of a relation R are the
members of the pairs constituting R, the items that R relates. The collection D
of all first terms of pairs in R is the domain of R; any collection with D as a
subcollection may also be so called. Similarly, the second terms of these pairs
make up or are a subcollection of the range counterdomain or converse domain of
R. One usually works within a set U such that R is a subset of the Cartesian
product U$U the set of all ordered pairs on U. Relations can be: 1 reflexive or
exhibit reflexivity: for all a, aRa. That is, a reflexive relation is one that,
like identity, each thing bears to itself. Examples: a weighs as much as b; or
the universal relation, i.e., the relation R such that for all a and b, aRb. 2
symmetrical or exhibit symmetry: for all a and b, aRb P bRa. In a symmetrical
relation, the order of the terms is reversible. Examples: a is a sibling of b;
a and b have a common divisor. Also symmetrical is the null relation, under
which no object is related to anything. 3 transitive or exhibit transitivity:
for all a, b, and c, aRb & bRc P aRc. Transitive relations carry across a
middle term. Examples: a is less than b; a is an ancestor of b. Thus, if a is
less than b and b is less than c, a is less than c: less than has carried across
the middle term, b. 4 antisymmetrical: for all a and b, aRb & bRa P a % b.
5 trichotomous, connected, or total trichotomy: for all a and b, aRb 7 bRa 7 a
% b. 6 asymmetrical: aRb & bRa holds for no a and b. 7 functional: for all
a, b, and c, aRb & aRc P b % c. In a functional relation which may also be
called a function, each first term uniquely determines a second term. R is
non-reflexive if it is not reflexive, i.e., if the condition 1 fails for at
least one object a. R is non-symmetric if 2 fails for at least one pair of
objects a, b. Analogously for non-transitive. R is irreflexive aliorelative if
1 holds for no object a and intransitive if 3 holds for no objects a, b, and c.
Thus understands is non-reflexive since some things do not understand themselves,
but not irreflexive, since some things do; loves is nonsymmetric but not
asymmetrical; and being a cousin of is non-transitive but not intransitive, as
being mother of is. 13 define an equivalence relation e.g., the identity
relation among numbers or the relation of being the same age as among people. A
class of objects bearing an equivalence relation R to each other is an
equivalence class under R. 1, 3, and 4 define a partial order; 3, 5, and 6 a
linear order. Similar properties define other important classifications, such
as lattice and Boolean algebra. The converse of a relation R is the set of all
pairs b, a such that aRb; the comreism relation 788 788 plement of R is the set of all pairs a,
b such that aRb i.e. aRb does not hold. A more complex example will show the
power of a relational vocabulary. The ancestral of R is the set of all a, b
such that either aRb or there are finitely many cI , c2, c3, . . . , cn such
that aRcI and c1Rc2 and c2Rc3 and . . . and cnRb. Frege introduced the ancestral
in his theory of number: the natural numbers are exactly those objects bearing
the ancestral of the successor-of relation to zero. Equivalently, they are the
intersection of all sets that contain zero and are closed under the successor
relation. This is formalizable in second-order logic. Frege’s idea has many
applications. E.g., assume a set U, relation R on U, and property F. An element
a of U is hereditarily F with respect to R if a is F and any object b which
bears the ancestral of R to a is also F. Hence F is here said to be a
hereditary property, and the set a is hereditarily finite with respect to the
membership relation if a is finite, its members are, as are the members of its
members, etc. The hereditarily finite sets or the sets hereditarily of cardinality
‹ k for any inaccessible k are an important subuniverse of the universe of
sets. Philosophical discussions of relations typically involve relations as
special cases of properties or sets. Thus nominalists and Platonists disagree
over the reality of relations, since they disagree about properties in general.
Similarly, one important connection is to formal semantics, where relations are
customarily taken as the denotations of relational predicates. Disputes about
the notion of essence are also pertinent. One says that a bears an internal
relation, R, to b provided a’s standing in R to b is an essential property of
a; otherwise a bears an external relation to b. If the essentialaccidental
distinction is accepted, then a thing’s essential properties will seem to
include certain of its relations to other things, so that we must admit
internal relations. Consider a point in space, which has no identity apart from
its place in a certain system. Similarly for a number. Or consider my hand,
which would perhaps not be the same object if it had not developed as part of
my body. If it is true that I could not have had other parents that possible persons similar to me but with
distinct parents would not really be me
then I, too, am internally related to other things, namely my parents.
Similar arguments would generate numerous internal relations for organisms,
artifacts, and natural objects in general. Internal relations will also seem to
exist among properties and relations themselves. Roundness is essentially a
kind of shape, and the relation larger than is essentially the converse of the
relation smaller than. In like usage, a relation between a and b is intrinsic
if it depends just on how a and b are; extrinsic if they have it in virtue of
their relation to other things. Thus, higher-than intrinsically relates the
Alps to the Appalachians. That I prefer viewing the former to the latter
establishes an extrinsic relation between the mountain ranges. Note that this
distinction is obscure as is internal-external. One could argue that the Alps
are higher than the Appalachians only in virtue of the relation of each to
something further, such as space, light rays, or measuring rods. Another issue
specific to the theory of relations is whether relations are real, given that
properties do exist. That is, someone might reject nominalism only to the
extent of admitting one-place properties. Although such doctrines have some
historical importance in, e.g., Plato and Bradley, they have disappeared. Since
relations are indispensable to modern logic and semantics, their inferiority to
one-place properties can no longer be seriously entertained. Hence relations
now have little independent significance in philosophy.
relational logic, the
formal study of the properties of and operations on binary relations that was
initiated by Peirce between 1870 and 2. Thus, in relational logic, one might
examine the formal properties of special kinds of relations, such as transitive
relations, or asymmetrical ones, or orderings of certain types. Or the focus
might be on various operations, such as that of forming the converse or
relative product. Formal deductive systems used in such studies are generally
known as calculi of relations.
relativism, the denial
that there are certain kinds of universal truths. There are two main types,
cognitive and ethical. Cognitive relativism holds that there are no universal
truths about the world: the world has no intrinsic characteristics, there are
just different ways of interpreting it. The Grecian Sophist Protagoras, the
first person on record to hold such a view, said, “Man is the measure of all
things; of things that are that they are, and of things that are not that they
are not.” Goodman, Putnam, and Rorty are contemporary philosophers who have held
versions of relativism. Rorty says, e.g., that “ ‘objective truth’ is no more
and no less than the best idea we currently have about how to explain what is
going on.” Critics of cognitive relativism contend that it is
self-referentially incoherent, since it presents its statements as universally
true, rather than simply relatively so. Ethical relativism is the theory that
there are no universally valid moral principles: all moral principles are valid
relative to culture or individual choice. There are two subtypes:
conventionalism, which holds that moral principles are valid relative to the
conventions of a given culture or society; and subjectivism, which maintains
that individual choices are what determine the validity of a moral principle.
Its motto is, Morality lies in the eyes of the beholder. As Ernest Hemingway
wrote, “So far, about morals, I know only that what is moral is what you feel
good after and what is immoral is what you feel bad after.” Conventionalist
ethical relativism consists of two theses: a diversity thesis, which specifies
that what is considered morally right and wrong varies from society to society,
so that there are no moral principles accepted by all societies; and a
dependency thesis, which specifies that all moral principles derive their
validity from cultural acceptance. From these two ideas relativists conclude
that there are no universally valid moral principles applying everywhere and at
all times. The first thesis, the diversity thesis, or what may simply be called
cultural relativism, is anthropological; it registers the fact that moral rules
differ from society to society. Although both ethical relativists and
non-relativists typically accept cultural relativism, it is often confused with
the normative thesis of ethical relativism. The opposite of ethical relativism
is ethical objectivism, which asserts that although cultures may differ in
their moral principles, some moral principles have universal validity. Even if,
e.g., a culture does not recognize a duty to refrain from gratuitous harm, that
principle is valid and the culture should adhere to it. There are two types of
ethical objectivism, strong and weak. Strong objectivism, sometimes called
absolutism, holds that there is one true moral system with specific moral rules.
The ethics of ancient Israel in the Old Testament with its hundreds of laws
exemplifies absolutism. Weak objectivism holds that there is a core morality, a
determinate set of principles that are universally valid usually including
prohibitions against killing the innocent, stealing, breaking of promises, and
lying. But weak objectivism accepts an indeterminate area where relativism is
legitimate, e.g., rules regarding sexual mores and regulations of property.
Both types of objectivism recognize what might be called application
relativism, the endeavor to apply moral rules where there is a conflict between
rules or where rules can be applied in different ways. For example, the ancient
Callactians ate their deceased parents but eschewed the impersonal practice of
burying them as disrespectful, whereas contemporary society has the opposite
attitudes about the care of dead relatives; but both practices exemplify the
same principle of the respect for the dead. According to objectivism, cultures
or forms of life can fail to exemplify an adequate moral community in at least
three ways: 1 the people are insufficiently intelligent to put constitutive
principles in order; 2 they are under considerable stress so that it becomes
too burdensome to live by moral principles; and 3 a combination of 1 and 2.
Ethical relativism is sometimes confused with ethical skepticism, the view that
we cannot know whether there are any valid moral principles. Ethical nihilism
holds that there are no valid moral principles. J. L. Mackie’s error theory is
a version of this view. Mackie held that while we all believe some moral
principles to be true, there are compelling arguments to the contrary. Ethical
objectivism must be distinguished from moral realism, the view that valid moral
principles are true, independently of human choice. Objectivism may be a form
of ethical constructivism, typified by Rawls, whereby objective principles are
simply those that impartial human beings would choose behind the veil of
ignorance. That is, the principles are not truly independent of hypothetical
human choices, but are constructs from those choices.
relativity, a term
applied to Einstein’s theories of electrodynamics special relativity, 5 and
gravitation general relativity, 6 because both hold that certain physical
quantities, formerly considered objective, are actually “relative to” the state
of motion of the observer. They are called “special” and “general” because, in
special relativity, electrodynamical laws determine a restricted class of
kinematical reference frames, the “inertial frames”; in general relativity, the
very distinction between inertial frames and others becomes a relative
distinction. Special relativity. Classical mechanics makes no distinction
between uniform motion and rest: not velocity, but acceleration is physically
detectable, and so different states of uniform motion are physically
equivalent. But classical electrodynamics describes light as wave motion with a
constant velocity through a medium, the “ether.” It follows that the measured
velocity of light should depend on the motion of the observer relative to the
medium. When interferometer experiments suggested that the velocity of light is
independent of the motion of the source, H. A. Lorentz proposed that objects in
motion contract in the direction of motion through the ether while their local
time “dilates”, and that this effect masks the difference in the velocity of
light. Einstein, however, associated the interferometry results with many other
indications that the theoretical distinction between uniform motion and rest in
the ether lacks empirical content. He therefore postulated that, in
electrodynamics as in mechanics, all states of uniform motion are equivalent.
To explain the apparent paradox that observers with different velocities can
agree on the velocity of light, he criticized the idea of an “absolute” or
frame-independent measure of simultaneity: simultaneity of distant events can
only be established by some kind of signaling, but experiment suggested that
light is the only signal with an invariant velocity, and observers in relative
motion who determine simultaneity with light signals obtain different results.
Furthermore, since objective measurement of time and length presupposes
absolute simultaneity, observers in relative motion will also disagree on time
and length. So Lorentz’s contraction and dilatation are not physical effects,
but consequences of the relativity of simultaneity, length, and time, to the
motion of the observer. But this relativity follows from the invariance of the
laws of electrodynamics, and the invariant content of the theory is expressed
geometrically in Minkowski spacetime. Logical empiricists took the theory as an
illustration of how epistemological analysis of a concept time could eliminate
empirically superfluous notions absolute simultaneity. General relativity.
Special relativity made the velocity of light a limit for all causal processes
and required revision of Newton’s theory of gravity as an instantaneous action
at a distance. General relativity incorporates gravity into the geometry of
space-time: instead of acting directly on one another, masses induce curvature
in space-time. Thus the paths of falling bodies represent not forced deviations
from the straight paths of a flat space-time, but “straightest” paths in a
curved space-time. While space-time is “locally” Minkowskian, its global
structure depends on mass-energy distribution. The insight behind this theory
is the equivalence of gravitational and inertial mass: since a given gravitational
field affects all bodies equally, weight is indistinguishable from the inertial
force of acceleration; freefall motion is indistinguishable from inertial
motion. This suggests that the Newtonian decomposition of free fall into
inertial and accelerated components is arbitrary, and that the freefall path
itself is the invariant basis for the structure of space-time. A philosophical
motive for the general theory was to extend the relativity of motion. Einstein
saw special relativity’s restricted class of equivalent reference frames as an
“epistemological defect,” and he sought laws that would apply to any frame. His
inspiration was Mach’s criticism of the Newtonian distinction between
“absolute” rotation and rotation relative to observable bodies like the “fixed
stars.” Einstein formulated Mach’s criticism as a fundamental principle: since
only relative motions are observable, local inertial effects should be
explained by the cosmic distribution of masses and by motion relative to them.
Thus not only velocity and rest, but motion in general would be relative.
Einstein hoped to effect this generalization by eliminating the distinction
between inertial frames and freely falling frames. Because free fall remains a
privileged state of motion, however, non-gravitational acceleration remains
detectable, and absolute rotation remains distinct from relative rotation.
Einstein also thought that relativity of motion would result from the general
covariance coordinate-independence of his theory i.e., that general equivalence of coordinate
systems meant general equivalence relativism, scientific relativity 791 791 of states of motion. It is now clear,
however, that general covariance is a mathematical property of physical theories
without direct implications about motion. So general relativity does not
“generalize” the relativity of motion as Einstein intended. Its great
accomplishments are the unification of gravity and geometry and the
generalization of special relativity to space-times of arbitrary curvature, which
has made possible the modern investigation of cosmological structure.
relevance logic, any of a
range of logics and philosophies of logic united by their insistence that the
premises of a valid inference must be relevant to the conclusion. Standard, or
classical, logic contains inferences that break this requirement, e.g., the
spread law, that from a contradiction any proposition whatsoever follows.
Relevance logic had its genesis in a system of strenge Implikation published by
Wilhelm Ackermann in 6. Ackermann’s idea for rejecting irrelevance was taken up
and developed by Alan Anderson and Nuel Belnap in a series of papers between 9
and Anderson’s death in 4. The first main summaries of these researches
appeared under their names, and those of many collaborators, in Entailment: The
Logic of Relevance and Necessity vol. 1, 5; vol. 2, 2. By the time of
Anderson’s death, a substantial research effort into relevance logic was under
way, and it has continued. Besides the rather vague unity of the idea of relevance
between premises and conclusion, there is a technical criterion often used to
mark out relevance logic, introduced by Belnap in 0, and applicable really only
to propositional logics the main focus of concern to date: a necessary
condition of relevance is that premises and conclusion should share a
propositional variable. Early attention was focused on systems E of entailment
and T of ticket entailment. Both are subsystems of C. I. Lewis’s system S4 of
strict implication and of classical truth-functional logic i.e., consequences
in E and T in ‘P’ are consequences in S4 in ‘ ’ and in classical logic in ‘/’.
Besides rejection of the spread law, probably the most notorious inference that
is rejected is disjunctive syllogism DS for extensional disjunction which is
equivalent to detachment for material implication: A 7 B,ÝA , B. The reason is
immediate, given acceptance of Simplification and Addition: Simplification
takes us from A & ÝA to each conjunct, and Addition turns the first
conjunct into A 7 B. Unless DS were rejected, the spread law would follow.
Since the late 0s, attention has shifted to the system R of relevant
implication, which adds permutation to E, to mingle systems which extend E and
R by the mingle law A P A P A, and to contraction-free logics, which
additionally reject contraction, in one form reading A P A P B P A P B. R minus
contraction RW differs from linear logic, much studied recently in computer
science, only by accepting the distribution of ‘&’ over ‘7’, which the
latter rejects. Like linear logic, relevance logic contains both
truth-functional and non-truth-functional connectives. Unlike linear logic,
however, R, E, and T are undecidable unusual among propositional logics. This
result was obtained only in 4. In the early 0s, relevance logics were given
possible-worlds semantics by several authors working independently. They also
have axiomatic, natural deduction, and sequent or consecution formulations. One
technical result that has attracted attention has been the demonstration that,
although relevance logics reject DS, they all accept Ackermann’s rule Gamma:
that if A 7 B and ÝA are theses, so is B. A recent result occasioning much
surprise was that relevant arithmetic consisting of Peano’s postulates on the
base of quantified R does not admit Gamma.
reliabilism, a type of
theory in epistemology that holds that what qualifies a belief as knowledge or
as epistemically justified is its reliable linkage to the truth. David
Armstrong motivates reliabilism with an analogy between a thermometer that
reliably indicates the temperature and a belief that reliably indicates the
truth. A belief qualifies as knowledge, he says, if there is a lawlike
connection in nature that guarantees that the belief is true. A cousin of the
nomic sufficiency account is the counterfactual approach, proposed by Dretske,
Goldman, and Nozick. A typical formulation of this approach says that a belief
qualifies relativity, general reliabilism 792
792 as knowledge if the belief is true and the cognizer has reasons for
believing it that would not obtain unless it were true. For example, someone
knows that the telephone is ringing if he believes this, it is true, and he has
a specific auditory experience that would not occur unless the telephone were
ringing. In a slightly different formulation, someone knows a proposition if he
believes it, it is true, and if it were not true he would not believe it. In
the example, if the telephone were not ringing, he would not believe that it
is, because he would not have the same auditory experience. These accounts are
guided by the idea that to know a proposition it is not sufficient that the
belief be “accidentally” true. Rather, the belief, or its mode of acquisition,
must “track,” “hook up with,” or “indicate” the truth. Unlike knowledge, justified
belief need not guarantee or be “hooked up” with the truth, for a justified
belief need not itself be true. Nonetheless, reliabilists insist that the
concept of justified belief also has a connection with truth acquisition.
According to Goldman’s reliable process account, a belief’s justificational
status depends on the psychological processes that produce or sustain it.
Justified beliefs are produced by appropriate psychological processes,
unjustified beliefs by inappropriate processes. For example, beliefs produced
or preserved by perception, memory, introspection, and “good” reasoning are
justified, whereas beliefs produced by hunch, wishful thinking, or “bad”
reasoning are unjustified. Why are the first group of processes appropriate and
the second inappropriate? The difference appears to lie in their reliability.
Among the beliefs produced by perception, introspection, or “good” reasoning, a
high proportion are true; but only a low proportion of beliefs produced by
hunch, wishful thinking, or “bad” reasoning are true. Thus, what qualifies a
belief as justified is its being the outcome of a sequence of reliable
belief-forming processes. Reliabilism is a species of epistemological
externalism, because it makes knowledge or justification depend on factors such
as truth connections or truth ratios that are outside the cognizer’s mind and
not necessarily accessible to him. Yet reliabilism typically emphasizes
internal factors as well, e.g., the cognitive processes responsible for a
belief. Process reliabilism is a form of naturalistic epistemology because it
centers on cognitive operations and thereby paves the way for cognitive
psychology to play a role in epistemology.
Renouvier, Charles
18153, philosopher influenced by Kant
and Comte, the latter being one of his teachers. Renouvier rejected many of the
views of both these philosophers, however, charting his own course. He
emphasized the irreducible plurality and individuality of all things against
the contemporary tendencies toward absolute idealism. Human individuality he
associated with indeterminism and freedom. To the extent that agents are
undetermined by other things and self-determining, they are unique individuals.
Indeterminism also extends to the physical world and to knowledge. He rejected
absolute certitude, but defended the universality of the laws of logic and
mathematics. In politics and religion, he emphasized individual freedom and
freedom of conscience. His emphasis on plurality, indeterminism, freedom,
novelty, and process influenced James and, through James, pragmatism.
re-praesentatum: Grice plays with this as a philosophical semanticist,
rather than a philosophical psychologist. But the re-praesentatum depends on
the ‘praesentatum,’ which corresponds to Grice’s sub-perceptum (not the
‘conceptus’). cf. Grice on Peirce’s representamen (“You don’t want to go
there,” – Grice to his tutees). It seems that in the one-off predicament,
iconicy plays a role: the drawing of a skull to indicate danger, the drawing of
an arrow at the fork of a road to indicate which way the emissor’s flowers, who
were left behind, are supposed to take (Carruthers). Suppose Grice joins the
Oxfordshire cricket club. He will represent Oxfordshire. He will do for
Oxfordshire what Oxfordshire cannot do for herself. Similarly, by uttering
“Smoke!,” the utterer means that there is fire somewhere. “Smoke!” is a
communication-device if it does for smoke what smoke cannot do for itself,
influence thoughts and behaviour. Or does it?! It MWheIGHT. But suppose that
the fire is some distant from the addresse. And the utterer HAS LEARNED That
there is fire in the distance. So he utters ‘Smoke!’ Where? Oh, you won’t see
it. But I was told there is smoke on the outskirts. Thanks for warning me!

Response: Chomsky hated it. Grice changed it to
‘effect.’ Or not. “Stimulus and response,” Skinner's
behavioral theory was largely set forth in his first book, Behavior of
Organisms (1938).[9] Here, he gives a systematic description of the manner in
which environmental variables control behavior. He distinguished two sorts of
behavior which are controlled in different ways: Respondent behaviors are
elicited by stimuli, and may be modified through respondent conditioning, often
called classical (or pavlovian) conditioning, in which a neutral stimulus is
paired with an eliciting stimulus. Such behaviors may be measured by their
latency or strength. Operant behaviors are 'emitted,' meaning that initially
they are not induced by any particular stimulus. They are strengthened through
operant conditioning (aka instrumental conditioning), in which the occurrence
of a response yields a reinforcer. Such behaviors may be measured by their
rate. Both of these sorts of behavior had already been studied experimentally,
most notably: respondents, by Ivan Pavlov;[25] and operants, by Edward
Thorndike.[26] Skinner's account differed in some ways from earlier ones,[27]
and was one of the first accounts to bring them under one roof.
rerum natura Latin, ‘the
nature of things’, metaphysics. The phrase can also be used more narrowly to
mean the nature of physical reality, and often it presupposes a naturalistic
view of all reality. Lucretius’s epic poem De rerum natura is an Epicurean
physics, designed to underpin the Epicurean morality.
Responsibility – cited by
H. P. Grice in “The causal theory of perception” -- a condition that relates an
agent to actions of, and consequences connected to, that agent, and is always
necessary and sometimes sufficient for the appropriateness of certain kinds of
appraisals of that agent. Responsibility has no single definition, but is
several closely connected specific concepts. Role responsibility. Agents are
identified by social roles that they occupy, say parent or professor. Typically
duties are associated with such roles to
care for the needs of their children, to attend classes and publish research
papers. A person in a social role is “responsible for” the execution of those
duties. One who carries out such duties is “a responsible person” or “is
behaving responsibly.” Causal responsibility. Events, including but not limited
to human actions, cause other events. The cause is “responsible” for the
effect. Causal responsibility does not imply consciousness; objects and natural
phenomena may have causal responsibility. Liability responsibility. Practices
of praise and blame include constraints on the mental stance that an agent must
have toward an action or a consequence of action, in order for praise or blame
to be appropriate. To meet such constraints is to meet a fundamental necessary
condition for liability for praise or blame
hence the expression ‘liability responsibility’. These constraints
include such factors as intention, knowledge, recklessness toward consequences,
absence of mistake, accident, inevitability of choice. An agent with the
capability for liability responsibility may lack it on some occasion when mistaken, for example. Capacity
responsibility. Practices of praise and blame assume a level of intellectual
and emotional capability. The severely mentally disadvantaged or the very
young, for example, do not have the capacity to meet the conditions for
liability responsibility. They are not “responsible” in that they lack capacity
responsibility. Both morality and law embody and respect these distinctions,
though law institutionalizes and formalizes them. Final or “bottom-line” assignment
of responsibility equivalent to indeed deserving praise or blame standardly
requires each of the latter three specific kinds of responsibility. The first
kind supplies some normative standards for praise or blame.
resultance, a relation
according to which one property the resultant property, sometimes called the
consequential property is possessed by some object or event in virtue of and
hence as a result of that object or event possessing some other property or set
of properties. The idea is that properties of things can be ordered into
connected levels, some being more basic than and giving rise to others, the
latter resulting from the former. For instance, a figure possesses the property
of being a triangle in virtue of its possessing a collection of properties,
including being a plane figure, having three sides, and so on; the former
resulting from the latter. An object is brittle has the property of being
brittle in virtue of having a certain molecular structure. It is often claimed
that moral properties like rightness and goodness are resultant properties: an
action is right in virtue of its possessing other properties. These examples
make it clear that the nature of the necessary connection holding between a
resultant property and those base properties that ground it may differ from
case to case. In the geometrical example, the very concept of being a triangle
grounds the resultance relation in question, and while brittleness is
nomologically related to the base properties from which it results, in the
moral case, the resultance relation is arguably neither conceptual nor
causal.
Richard Rufus, also
called Richard of Cornwall d. c.1260, English philosopher-theologian who wrote
some of the earliest commentaries on Aristotle in the Latin West. His commentaries
were not cursory summaries; they included sustained philosophical discussions.
Richard was a master of arts at Paris, where he studied with Alexander of
Hales; he was also deeply influenced by Robert Grosseteste. He left Paris and
joined the Franciscan order in 1238; he was ordained in England. In 1256, he
became regent master of the Franciscan studium at Oxford; according to Roger
Bacon, he was the most influential philosophical theologian at Oxford in the
second half of the thirteenth century. In addition to his Aristotle
commentaries, Richard wrote two commentaries on Peter Lombard’s Sentences
c.1250, c.1254. In the first of these he borrowed freely from Robert
Grosseteste, Alexander of Hales, and Richard Fishacre; the second commentary
was a critical condensation of the lectures of his younger contemporary, St.
Bonaventure, presented in Paris. Richard Rufus was the first medieval proponent
of the theory of impetus; his views on projectile motion were cited by
Franciscus Meyronnes. He also advocated other arguments first presented by
Johannes Philoponus. Against the eternity of the world, he argued: 1 past time
is necessarily finite, since it has been traversed, and 2 the world is not
eternal, since if the world had no beginning, no more time would transpire
before tomorrow than before today. He also argued that if the world had not be
en created ex nihilo, the
first cause would be mutable. Robert Grosseteste cited one of Richard’s
arguments against the eternity of the world in his notes on Aristotle’s
Physics. In theology, Richard denied the validity of Anselm’s ontological
argument, but, anticipating Duns Scotus, he argued that the existence of an
independent being could be inferred from its possibility. Like Duns Scotus, he
employs the formal distinction as an explanatory tool; in presenting his own
views, Duns Scotus cited Richard’s definition of the formal distinction.
Richard stated his philosophical views briefly, even cryptically; his Latin
prose style is sometimes eccentric, characterized by interjections in which he
addresses questions to God, himself, and his readers. He was hesitant about the
value of systematic theology for the theologian, deferring to biblical
exposition as the primary forum for theological discussion. In systematic theology,
he emphasized Aristotelian philosophy and logic. He was a well-known logician;
some scholars believe he is the famous logician known as the Magister
Abstractionum. Though he borrowed freely from his contemporaries, he was a
profoundly original philosopher.
Ricoeur, P. hermeneuticist and phenomenologist who has
been a professor at several universities
as well as the of Naples, Yale , and the of Chicago. He has received major prizes from
France, G.y, and Italy. He is the author of twenty-some volumes tr. in a
variety of languages. Among his best-known books are Freedom and Nature: The
Voluntary and the Involuntary; Freud and Philosophy: An Essay of
Interpretation; The Conflict of Interpretations: Essay in Hermeneutics; The
Role of the Metaphor: Multi-Disciplinary Studies of the Creation of Meaning in
Language, Time and Narrative; and Oneself as Another. His early studies with
the existentialist Marcel resulted in a
book-length study of Marcel’s work and later a series of published dialogues
with him. Ricoeur’s philosophical enterprise is colored by a continuing tension
between faith and reason. His long-standing commitments to both the
significance of the individual and the Christian faith are reflected in his
hermeneutical voyage, his commitment to the Esprit movement, and his interest
in the writings of Emmanuel Mounier. This latter point is also seen in his
claim of the inseparability of action and discourse in our quest for meaning.
In our comprehension of both history and fiction one must turn to the text to
understand its plot as guideline if we are to comprehend experience of any
reflective sort. In the end there are no metaphysical or epistemological
grounds by which meaning can be verified, and yet our nature is such that
possibility must be present before us. Ricoeur attempts his explanation through
a hermeneutic phenomenology. The very hermeneutics of existence that follows is
itself limited by reason’s questioning of experience and its attempts to
transcend the limit through the language of symbols and metaphors. Freedom and
meaning come to be realized in the actualization of an ethics that arises out
of the very act of existing and thus transcends the mere natural voluntary
distinction of a formal ethic. It is clear from his later work that he rejects
any form of foundationalism including phenomenology as well as nihilism and
easy skepticism. Through a sort of interdependent dialectic that goes beyond
the more mechanical models of Hegelianism or Marxism, the self understands
itself and is understood by the other in terms of its suffering and its moral
actions.
rights, advantageous
positions conferred on some possessor by law, morals, rules, or other norms.
There is no agreement on the sense in which rights are advantages. Will
theories hold that rights favor the will of the possessor over the conflicting
will of some other party; interest theories maintain that rights serve to
protect or promote the interests of the right-holder. Hohfeld identified four
legal advantages: liberties, claims, powers, and immunities. The concept of a
right arose in Roman jurisprudence and was extended to ethics via natural law
theory. Just as positive law, the law posited by human lawmakers, confers legal
rights, so the natural law confers natural rights. Rights are classified by
their specific sources in different sorts of rules. Legal rights are
advantageous positions under the law of a society. Other species of
institutional rights are conferred by the rules of private organizations, of
the moral code of a society, or even of some game. Those who identify natural
law with the moral law often identify natural rights with moral rights, but
some limit natural rights to our most fundamental rights and contrast them with
ordinary moral rights. Others deny that moral rights are natural because they
believe that they are conferred by the mores or positive morality of one’s
society. One always possesses any specific right by virtue of possessing some
status. Thus, rights are also classified by status. Civil rights are those one
possesses as a citizen; human rights are possessed by virtue of being human.
Presumably women’s rights, children’s rights, patients’ rights, and the rights
of blacks as such are analogous. Human rights play very much the same role in
ethics once played by natural rights. This is partly because ontological doubts
about the existence of God undermine the acceptance of any natural law taken to
consist in divine commands, and epistemological doubts about self-evident moral
truths lead many to reject any natural law conceived of as the dictates of
reason. Although the Thomistic view that natural rights are grounded on the
nature of man is often advocated, most moral philosophers reject its
teleological conception of human nature defined by essential human purposes. It
seems simpler to appeal instead to fundamental rights that must be universal
among human beings because they are possessed merely by virtue of one’s status
as a human being. Human rights are still thought of as natural in the very
broad sense of existing independently of any human action or institution. This
explains how they can be used as an independent standard in terms of which to
criticize the laws and policies of governments and other organizations. Since
human rights are classified by status rather than source, there is another
species of human rights that are institutional rather than natural. These are
the human rights that have been incorporated into legal systems by
international agreements such as the European Convention on Human Rights. It is
sometimes said that while natural rights were conceived as purely negative
rights, such as the right not to be arbitrarily imprisoned, human rights are
conceived more broadly to include positive social and economic rights, such as
the right to social security or to an adequate standard of living. But this is
surely not true by definition. Traditional natural law theorists such as
Grotius and Locke spoke of natural rights as powers and associated them with
liberties, rather than with claims against interference. And while modern
declarations of human rights typically include social and economic rights, they
assume that these are rights in the same sense that traditional political
rights are. Rights are often classified by their formal properties. For
example, the right not to be battered is a negative right because it imposes a
negative duty not to batter, while the creditor’s right to be repaid is a
positive right because it imposes a positive duty to repay. The right to be
repaid is also a passive right because its content is properly formulated in
the passive voice, while the right to defend oneself is an active right because
its content is best stated in the active voice. Again, a right in rem is a
right that holds against all second parties; a right in personam is a right
that holds against one or a few others. This is not quite Hart’s distinction
between general and special rights, rights of everyone against everyone, such
as the right to free speech, and rights arising from special relations, such as
that between creditor and debtor or husband and wife. Rights are conceptually
contrasted with duties because rights are advantages while duties are
disadvantages. Still, many jurists and philosophers have held that rights and
duties are logical correlatives. This does seem to be true of claim rights;
thus, the creditor’s right to be repaid implies the debtor’s duty to repay and
vice versa. But the logical correlative of a liberty right, such as one’s right
to park in front of one’s house, is the absence of any duty for one not to do
so. This contrast is indicated by D. D. Raphael’s distinction between rights of
recipience and rights of action. Sometimes to say that one has a right to do
something is to say merely that it is not wrong for one to act in this way.
This has been called the weak sense of ‘a right’. More often to assert that one
has a right to do something does not imply that exercising this right is right.
Thus, I might have a right to refuse to do a favor for a friend even though it
would be wrong for me to do so. Finally, many philosophers distinguish between
absolute and prima facie rights. An absolute right always holds, i.e.,
disadvantages some second party, within its scope; a prima facie right is one
that holds unless the ground of the right is outweighed by some stronger
contrary reason.
rigorism, the view that
morality consists in that single set of simple or unqualified moral rules,
discoverable by reason, which applies to all human beings at all times. It is
often said that Kant’s doctrine of the categorical imperative is rigoristic.
Two main objections to rigorism are 1 some moral rules do not apply
universally e.g., ‘Promises should be
kept’ applies only where there is an institution of promising; and 2 some rules
that could be universally kept are absurd
e.g., that everyone should stand on one leg while the sun rises. Recent
interpreters of Kant defend him against these objections by arguing, e.g., that
the “rules” he had in mind are general guidelines for living well, which are in
fact universal and practically relevant, or that he was not a rigorist at all,
seeing moral worth as issuing primarily from the agent’s character rather than
adherence to rules.
ring of Gyges, a ring
that gives its wearer invisibility, discussed in Plato’s Republic II, 359b
360d. Glaucon tells the story of a man who discovered the ring and used it to
usurp the throne to defend the claim that those who behave justly do so only
because they lack the power to act unjustly. If they could avoid paying the
penalty of injustice, Glaucon argues, everyone would be unjust.

Rorty, R. philosopher,
notable for the breadth of his philosophical and cultural interests. He was
educated at the of Chicago and Yale and
has taught at Wellesley, Princeton, Virginia, and Stanford. His early work was
primarily in standard areas of analytic philosophy such as the philosophy of
mind, where, for example, he developed an important defense of eliminative
materialism. In 9, however, he published Philosophy and the Mirror of Nature,
which was both hailed and denounced as a fundamental critique of analytic
philosophy. Both the praise and the abuse were often based on misconceptions,
but there is no doubt that Rorty questioned fundamental presuppositions of many
Anglo- philosophers and showed affinities for Continental alternatives to
analytic philosophy. At root, however, Rorty’s position is neither analytic
except in its stylistic clarity nor Continental except in its cultural breadth.
His view is, rather, pragmatic, a contemporary incarnation of the
distinctively philosophizing of James,
Peirce, and Dewey. On Rorty’s reading, pragmatism involves a rejection of the
representationalism that has dominated modern philosophy from Descartes through
logical positivism. According to representationalism, we have direct access
only to ideas that represent the world, not to the world itself. Philosophy has
the privileged role of determining the criteria for judging that our
representations are adequate to reality. A main thrust of Philosophy and the
Mirror of Nature is to discredit representationalism, first by showing how it
has functioned as an unjustified presupposition in classical modern
philosophers such as Descartes, Locke, and Kant, and second by showing how
analytic philosophers such as Wilfrid Sellars and Quine have revealed the
incoherence of representationalist assumptions in contemporary epistemology.
Since, on Rorty’s view, representationalism defines the epistemological project
of modern philosophy, its failure requires that we abandon this project and,
with it, traditional pretensions to a privileged cognitive role for philosophy.
Rorty sees no point in seeking a non-representationalist basis for the
justification or the truth of our knowledge claims. It is enough to accept as
justified beliefs those on which our epistemic community agrees and to use
‘true’ as an honorific term for beliefs that we see as “justified to the hilt.”
Rorty characterizes his positive position as “liberal ironism.” His liberalism
is of a standard sort, taking as its basic value the freedom of all
individuals: first, their freedom from suffering, but then also freedom to form
their lives with whatever values they find most compelling. Rorty distinguishes
the “public sphere” in which we all share the liberal commitment to universal
freedom from the “private spheres” in which we all work out our own specific
conception of the good. His ironism reflects his realization that there is no
grounding for public or private values other than our deep but contingent
commitment to them and his appreciation of the multitude of private values that
he does not himself happen to share. Rorty has emphasized the importance of
literature and literary criticism as
opposed to traditional philosophy for
providing the citizens of a liberal society with appropriate sensitivities to
the needs and values of others.
Roscelin de Compiègne,
philosopher and logician who became embroiled in theological controversy when
he applied his logical teachings to the doctrine of the Trinity. Since almost
nothing survives of his written work, we must rely on hostile accounts of his
views by Anselm of Canterbury and Peter Abelard, both of whom openly opposed
his positions. Perhaps the most notorious view Roscelin is said to have held is
that universals are merely the puffs of air produced when a word is pronounced.
On this point he opposed views current among many theologians that a universal
has an existence independent of language, and somehow is what many different
particulars are. Roscelin’s aversion to any proposal that different things can
be some one thing is probably what led him in his thinking about the three
persons of God to a position that sounded suspiciously like the heresy of
tritheism. Roscelin also evidently held that the qualities of things are not
entities distinct from the subjects that possess them. This indicates that
Roscelin probably denied that terms in the Aristotelian categories other than
substance signified anything distinct from substances. Abelard, the foremost
logician of the twelfth century, studied under Roscelin around 1095 and was
undoubtedly influenced by him on the question of universals. Roscelin’s view
that universals are linguistic entities remained an important option in
medieval thought. Otherwise his positions do not appear to have had much
currency in the ensuing decades.
Rosenzweig, F. G.
philosopher and Jewish theologian known as one of the founders of religious
existentialism. His early relation to Judaism was tenuous, and at one point he
came close to converting to Christianity. A religious experience in a synagogue
made him change his mind and return to Judaism. His chief philosophic works are
a two-volume study, Hegel and the State 0, and his masterpiece, The Star of
Redemption 1. Rosenzweig’s experience in World War I caused him to reject
absolute idealism on the ground that it cannot account for the privacy and
finality of death. Instead of looking for a unifying principle behind
existence, Rosenzweig starts with three independent realities “given” in
experience: God, the self, and the world. Calling his method “radical
empiricism,” he explains how God, the self, and the world are connected by three
primary relations: creation, revelation, and redemption. In revelation, God
does not communicate verbal statements but merely a presence that calls for
love and devotion from worshipers.
Rosmini-Serbati, Antonio,
philosopher, Catholic priest, counselor to Pope Pius IX, and supporter of the
supremacy of the church over civil government Neo-Guelphism. Rosmini had two
major concerns: the objectivity of human knowledge and the synthesis of
philosophical thought within the tradition of Catholic thought. In his Nuovo
saggio sull’origine delle idee “New Essay on the Origin of Ideas,” 1830, he
identifies the universal a priori intuitive component of all human knowledge
with the idea of being that gives us the notion of a possible or ideal being.
Everything in the world is known by intellectual perception, which is the
synthesis of sensation and the idea of being. Except for the idea of being,
which is directly given by God, all ideas derive from abstraction. The
objectivity of human knowledge rests on its universal origin in the idea of
being. The harmony between philosophy and religion comes from the fact that all
human knowledge is the result of divine revelation. Rosmini’s thought was
influenced by Augustine and Aquinas, and stimulated by the attempt to find a solution
to the contrasting needs of rationalism and empiricism.
Ross: w. d. Aristotelian
scholar and moral philosopher. Born in Edinburgh and educated at the of Edinburgh and at Balliol , Oxford, he
became a fellow of Merton , then a fellow, tutor, and eventually provost at
Oriel . He was vice-chancellor of Oxford
144 and president of the British Academy 640. He was knighted in 8 in
view of national service. Ross was a distinguished classical scholar: he edited
the Oxford translations of Aristotle 831 and tr. the Metaphysics and the Ethics
himself. His Aristotle 3 is a judicious exposition of Aristotle’s work as a
whole. Kant’s Ethical Theory 4 is a commentary on Kant’s The Groundwork of
Ethics. His major contribution to philosophy was in ethics: The Right and the
Good 0 and Foundations of Ethics9. The view he expressed there was
controversial in English-speaking countries for ten years or so. He held that
‘right’ and ‘good’ are empirically indefinable terms that name objective
properties the presence of which is known intuitively by persons who are mature
and educated. We first cognize them in particular instances, then arrive at
general principles involving them by “intuitive induction.” He thought every
ethical theory must admit at least one intuition. The knowledge of moral
principles is thus rather like knowledge of the principles of geometry. ‘Right’
‘dutiful’ applies to acts, in the sense of what an agent brings about and there
is no duty to act from a good motive, and a right act can have a bad motive;
‘morally good’ applies primarily to the desires that bring about action. He
castigated utilitarianism as absorbing all duties into enhancing the wellbeing
of everyone affected, whereas in fact we have strong special obligations to
keep promises, make reparation for injuries, repay services done, distribute
happiness in accord with merit, benefit individuals generally and he concedes
this is a weighty matter and ourselves only in respect of knowledge and virtue,
and not injure others normally a stronger obligation than that to benefit. That
we have these “prima facie” duties is self-evident, but they are only prima
facie in the sense that they are actual duties only if there is no stronger
conflicting prima facie duty; and when prima facie duties conflict, what one
ought to do is what satisfies all of them best
although which this is is a matter of judgment, not self-evidence. He
conceded, however, in contrast to his general critique of utilitarianism, that
public support of these prima facie principles with their intuitive strength
can be justified on utilitarian grounds. To meet various counterexamples Ross
introduced complications, such as that a promise is not binding if discharge of
it will not benefit the promisee providing this was an implicit understanding,
and it is less binding if made long ago or in a casual manner. Only four states
of affairs are good in themselves: desire to do one’s duty virtue, knowledge,
pleasure, and the distribution of happiness in accordance with desert. Of
these, virtue is more valuable than any amount of knowledge or pleasure. In
Foundations of Ethics he held that virtue and pleasure are not good in the same
sense: virtue is “admirable” but pleasure only a “worthy object of
satisfaction” so ‘good’ does not name just one property.
Rousseau, Jean-Jacques,
philosopher, essayist, novelist, and musician, best known for his theories on
social freedom and societal rights, education, and religion. Born in Geneva, he
was largely self-educated and moved to France as a teenager. Throughout much of
his life he moved between Paris and the provinces with several trips abroad
including a Scottish stay with Hume and a return visit to Geneva, where he
reconverted to Protestantism from his earlier conversion to Catholicism. For a
time he was a friend of Diderot and other philosophes and was asked to
contribute articles on music for the Encyclopedia. Rousseau’s work can be seen
from at least three perspectives. As social contract theorist, he attempts to
construct a hypothetical state of nature to explain the current human
situation. This evolves a form of philosophical anthropology that gives us both
a theory of human nature and a series of pragmatic claims concerning social
organization. As a social commentator, he speaks of both practical and ideal
forms of education and social organization. As a moralist, he continually
attempts to unite the individual and the citizen through some form of universal
political action or consent. In Discourse on the Origin and Foundation of
Inequality Among Mankind 1755, Rousseau presents us with an almost idyllic view
of humanity. In nature humans are first seen as little more than animals except
for their special species sympathy. Later, through an explanation of the
development of reason and language, he is able to suggest how humans, while
retaining this sympathy, can, by distancing themselves from nature, understand
their individual selves. This leads to natural community and the closest thing
to what Rousseau considers humanity’s perfect moment. Private property quickly
follows on the division of labor, and humans find themselves alienated from
each other by the class divisions engendered by private property. Thus man, who
was born in freedom, now finds himself in chains. The Social Contract or
Principles of Political Right 1762 has a more ambitious goal. With an account
of the practical role of the legislator and the introduction of the concept of
the general will, Rousseau attempts to give us a foundation for good government
by presenting a solution to the conflicts between the particular and the
universal, the individual and the citizen, and the actual and the moral.
Individuals, freely agreeing to a social pact and giving up their rights to the
community, are assured of the liberties and equality of political citizenship
found in the contract. It is only through being a citizen that the individual
can fully realize his freedom and exercise his moral rights and duties. While
the individual is naturally good, he must always guard against being dominated
or dominating. Rousseau finds a solution to the problems of individual freedoms
and interests in a superior form of moral/political action that he calls the
general will. The individual as citizen substitutes “I must” for “I will,”
which is also an “I shall” when it expresses assent to the general will. The
general will is a universal force or statement and thus is more noble than any
particular will. In willing his own interest, the citizen is at the same time
willing what is communally good. The particular and the universal are united.
The individual human participant realizes himself in realizing the good of all.
As a practical political commentator Rousseau knew that the universal and the
particular do not always coincide. For this he introduced the idea of the
legislator, which allows the individual citizen to realize his fulfillment as
social being and to exercise his individual rights through universal consent.
In moments of difference between the majority will and the general will the
legislator will instill the correct moral/political understanding. This will be
represented in the laws. While sovereignty rests with the citizens, Rousseau
does not require that political action be direct. Although all government
should be democratic, various forms of government from representative democracy
preferable in small societies to strong monarchies preferable in large
nation-states may be acceptable. To shore up the unity and stability of
individual societies, Rousseau suggests a sort of civic religion to which all
citizens subscribe and in which all members participate. His earlier writings
on education and his later practical treatises on the governments of Poland and
Corsica reflect related concerns with natural and moral development and with
historical and geographical considerations.
Royce, J. philosopher
best known for his pragmatic idealism, his ethics of loyalty, and his theory of
community. Educated at Berkeley, at Johns Hopkins, and in G.y, he taught
philosophy at Harvard from 2. Royce held that a concept of the absolute or
eternal was needed to account for truth, ultimate meaning, and reality in the
face of very real evil in human experience. Seeking to reconcile individuals
with the Absolute, he postulated, in The World and the Individual 9,1, Absolute
Will and Thought as an expression of the concrete and differentiated
individuality of the world. Royce saw the individual self as both moral and
sinful, developing through social interaction, community experience, and
communal and self-interpretation. Self is constituted by a life plan, by
loyalty to an ultimate goal. Yet selflimitation and egoism, two human sins,
work against achievement of individual goals, perhaps rendering life a
senseless failure. The self needs saving and this is the message of religion,
argues Royce The Religious Aspects of Philosophy, 5; The Sources of Religious
Insight, 2. For Royce, the instrument of salvation is the community. In The
Philosophy of Loyalty 8, he develops an ethics of loyalty to loyalty, i.e., the
extension of loyalty throughout the human community. In The Problem of
Christianity 3, Royce presents a doctrine of community that overcomes the
individualismcollectivism dilemma and allows a genuine blending of individual
and social will. Community is built through interpretation, a mediative process
that reconciles two ideas, goals, and persons, bringing common meaning and
understanding. Interpretation involves respect for selves as dynamos of ideas
and purposes, the will to interpret, dissatisfaction with partial meanings and
narrowness of view, reciprocity, and mutuality. In this work, the Absolute is a
“Community of Interpretation and Hope,” in which there is an endlessly
accumulating series of interpretations and significant deeds. An individual
contribution thus is not lost but becomes an indispensable element in the
divine life. Among Royce’s influential students were C. I. Lewis, William
Ernest Hocking, Norbert Wiener, Santayana, and T. S. Eliot.
rule of law, the largely
formal or procedural properties of a well-ordered legal system. Commonly, these
properties are thought to include: a prohibition of arbitrary power the
lawgiver is also subject to the laws; laws that are general, prospective, clear,
and consistent capable of guiding conduct; and tribunals courts that are
reasonably accessible and fairly structured to hear and determine legal claims.
Contemporary discussions of the rule of law focus on two major questions: 1 to
what extent is conformity to the rule of law essential to the very idea of a
legal system; and 2 what is the connection between the rule of law and the
substantive moral value of a legal system?
Russell, Bertrand Arthur
William, philosopher, logician, social reformer, and man of letters, one of the
founders of analytic philosophy. Born of Celtic Highland stock into an
aristocratic family in Wales (then part of England), Russell always divided his
interests between politics, philosophy, and the ladies (he married six times). Orphaned
at four, he was brought up by his grandmother, who educated him at home with
the help of “rather dull” tutors. He studied mathematics at Cambridge and then,
as his grandmother says, ‘out of the blue,’ he turned to philosophy. At home he
had absorbed J. S. Mill’s liberalism, but not his empiricism. At Cambridge he
came under the influence of neo-Hegelianism, especially the idealism of
McTaggart, Ward his tutor, and Bradley. His earliest logical views were
influenced most by Bradley, especially Bradley’s rejection of psychologism.
But, like Ward and McTaggart, he rejected Bradley’s metaphysical monism in
favor of pluralism or monadism. Even as an idealist, he held that scientific
knowledge was the best available and that philosophy should be built around it.
Through many subsequent changes, this belief about science, his pluralism, and
his anti-psychologism remained constant. In 5, he conceived the idea of an
idealist encyclopedia of the sciences to be developed by the use of
transcendental arguments to establish the conditions under which the special
sciences are possible. Russell’s first philosophical book, An Essay on the
Foundations of Geometry 7, was part of this project, as were other mostly
unfinished and unpublished pieces on physics and arithmetic written at this
time see his Collected Papers, vols. 12. Russell claimed, in contrast to Kant,
to use transcendental arguments in a purely logical way compatible with his
anti-psychologism. In this case, however, it should be both possible and
preferable to replace them by purely deductive arguments. Another problem arose
in connection with asymmetrical relations, which led to contradictions if
treated as internal relations, but which were essential for any treatment of
mathematics. Russell resolved both problems in 8 by abandoning idealism
including internal relations and his Kantian methodology. He called this the
one real revolution in his philosophy. With his Cambridge contemporary Moore,
he adopted an extreme Platonic realism, fully stated in The Principles of
Mathematics 3 though anticipated in A Critical Exposition of the Philosophy of
Leibniz 0. Russell’s work on the sciences was by then concentrated on pure
mathematics, but the new philosophy yielded little progress until, in 0, he
discovered Peano’s symbolic logic, which offered hope that pure mathematics
could be treated without Kantian intuitions or transcendental arguments. On
this basis Russell propounded logicism, the claim that the whole of pure
mathematics could be derived deductively from logical principles, a position he
came to independently of Frege, who held a similar but more restricted view but
whose work Russell discovered only later. Logicism was announced in The
Principles of Mathematics; its development occupied Russell, in collaboration
with Whitehead, for the next ten years. Their results were published in
Principia Mathematica 013, 3 vols., in which detailed derivations were given
for Cantor’s set theory, finite and transfinite arithmetic, and elementary
parts of measure theory. As a demonstration of Russell’s logicism, Principia
depends upon much prior arithmetization of mathematics, e.g. of analysis, which
is not explicitly treated. Even with these allowances much is still left out:
e.g., abstract algebra and statistics. Russell’s unpublished papers Papers,
vols. 45, however, contain logical innovations not included in Principia, e.g.,
anticipations of Church’s lambda-calculus. On Russell’s extreme realism,
everything that can be referred to is a term that has being though not necessarily
existence. The combination of terms by means of a relation results in a complex
term, which is a proposition. Terms are neither linguistic nor psychological.
The first task of philosophy is the theoretical analysis of propositions into
their constituents. The propositions of logic are unique in that they remain
true when any of their terms apart from logical constants are replaced by any
other terms. In 1 Russell discovered that this position fell prey to
self-referential paradoxes. For example, if the combination of any number of
terms is a new term, the combination of all terms is a term distinct from any
term. The most famous such paradox is called Russell’s paradox. Russell’s
solution was the theory of types, which banned self-reference by stratifying
terms and expressions into complex hierarchies of disjoint subclasses. The
expression ‘all terms’, e.g., is then meaningless unless restricted to terms of
specified types, and the combination of terms of a given type is a term of
different type. A simple version of the theory appeared in Principles of
Mathematics appendix A, but did not eliminate all the paradoxes. Russell
developed a more elaborate version that did, in “Mathematical Logic as Based on
the Theory of Types” 8 and in Principia. From 3 to 8 Russell sought to preserve
his earlier account of logic by finding other ways to avoid the paradoxes including a well-developed substitutional
theory of classes and relations posthumously published in Essays in Analysis,
4, and Papers, vol. 5. Other costs of type theory for Russell’s logicism
included the vastly increased complexity of the resulting sysRussell, Bertrand
Arthur William Russell, Bertrand Arthur William 802 802 tem and the admission of the problematic
axiom of reducibility. Two other difficulties with Russell’s extreme realism
had important consequences: 1 ‘I met Quine’ and ‘I met a man’ are different
propositions, even when Quine is the man I met. In the Principles, the first
proposition contains a man, while the second contains a denoting concept that
denotes the man. Denoting concepts are like Fregean senses; they are meanings
and have denotations. When one occurs in a proposition the proposition is not
about the concept but its denotation. This theory requires that there be some way
in which a denoting concept, rather than its denotation, can be denoted. After
much effort, Russell concluded in “On Denoting” 5 that this was impossible and
eliminated denoting concepts as intermediaries between denoting phrases and
their denotations by means of his theory of descriptions. Using firstorder
predicate logic, Russell showed in a broad, though not comprehensive range of
cases how denoting phrases could be eliminated in favor of predicates and
quantified variables, for which logically proper names could be substituted.
These were names of objects of acquaintance
represented in ordinary language by ‘this’ and ‘that’. Most names, he
thought, were disguised definite descriptions. Similar techniques were applied
elsewhere to other kinds of expression e.g. class names resulting in the more
general theory of incomplete symbols. One important consequence of this was
that the ontological commitments of a theory could be reduced by reformulating
the theory to remove expressions that apparently denoted problematic entities.
2 The theory of incomplete symbols also helped solve extreme realism’s
epistemic problems, namely how to account for knowledge of terms that do not
exist, and for the distinction between true and false propositions. First, the
theory explained how knowledge of a wide range of items could be achieved by
knowledge by acquaintance of a much narrower range. Second, propositional
expressions were treated as incomplete symbols and eliminated in favor of their
constituents and a propositional attitude by Russell’s multiple relation theory
of judgment. These innovations marked the end of Russell’s extreme realism,
though he remained a Platonist in that he included universals among the objects
of acquaintance. Russell referred to all his philosophy after 8 as logical
atomism, indicating thereby that certain categories of items were taken as
basic and items in other categories were constructed from them by rigorous
logical means. It depends therefore upon reduction, which became a key concept
in early analytic philosophy. Logical atomism changed as Russell’s logic
developed and as more philosophical consequences were drawn from its
application, but the label is now most often applied to the modified realism
Russell held from 5 to 9. Logic was central to Russell’s philosophy from 0
onward, and much of his fertility and importance as a philosopher came from his
application of the new logic to old problems. In 0 Russell became a lecturer at
Cambridge. There his interests turned to epistemology. In writing a popular
book, Problems of Philosophy 2, he first came to appreciate the work of the
British empiricists, especially Hume and Berkeley. He held that empirical
knowledge is based on direct acquaintance with sense-data, and that matter
itself, of which we have only knowledge by description, is postulated as the
best explanation of sense-data. He soon became dissatisfied with this idea and
proposed instead that matter be logically constructed out of sensedata and
unsensed sensibilia, thereby obviating dubious inferences to material objects
as the causes of sensations. This proposal was inspired by the successful
constructions of mathematical concepts in Principia. He planned a large work,
“Theory of Knowledge,” which was to use the multiple relation theory to extend
his account from acquaintance to belief and inference Papers, vol. 7. However,
the project was abandoned as incomplete in the face of Vitters’s attacks on the
multiple relation theory, and Russell published only those portions dealing
with acquaintance. The construction of matter, however, went ahead, at least in
outline, in Our Knowledge of the External World 4, though the only detailed
constructions were undertaken later by Carnap. On Russell’s account, material
objects are those series of sensibilia that obey the laws of physics.
Sensibilia of which a mind is aware sense-data provide the experiential basis
for that mind’s knowledge of the physical world. This theory is similar, though
not identical, to phenomenalism. Russell saw the theory as an application of
Ockham’s razor, by which postulated entities were replaced by logical
constructions. He devoted much time to understanding modern physics, including
relativity and quantum theory, and in The Analysis of Matter 7 he incorporated
the fundamental ideas of those theories into his construction of the physical
world. In this book he abandoned sensibilia as fundamental constituents of the
world in favor Russell, Bertrand Arthur William Russell, Bertrand Arthur
William 803 803 of events, which were
“neutral” because intrinsically neither physical nor mental. In 6 Russell was
dismissed from Cambridge on political grounds and from that time on had to earn
his living by writing and public lecturing. His popular lectures, “The
Philosophy of Logical Atomism” 8, were a result of this. These lectures form an
interim work, looking back on the logical achievements of 510 and emphasizing
their importance for philosophy, while taking stock of the problems raised by
Vitters’s criticisms of the multiple relation theory. In 9 Russell’s philosophy
of mind underwent substantial changes, partly in response to those criticisms.
The changes appeared in “On Propositions: What They Are and How They Mean” 9
and The Analysis of Mind 1, where the influence of contemporary trends in
psychology, especially behaviorism, is evident. Russell gave up the view that
minds are among the fundamental constituents of the world, and adopted neutral
monism, already advocated by Mach, James, and the New Realists. On Russell’s neutral monism, a
mind is constituted by a set of events related by subjective temporal relations
simultaneity, successiveness and by certain special “mnemic” causal laws. In
this way he was able to explain the apparent fact that “Hume’s inability to
perceive himself was not peculiar.” In place of the multiple relation theory
Russell identified the contents of beliefs with images “imagepropositions” and
words “word-propositions”, understood as certain sorts of events, and analyzed
truth qua correspondence in terms of resemblance and causal relations. From 8
to 4 Russell lived in the United States, where he wrote An Inquiry into Meaning
and Truth 0 and his popular A History of Western Philosophy 5. His
philosophical attention turned from metaphysics to epistemology and he
continued to work in this field after he returned in 4 to Cambridge, where he
completed his last major philosophical work, Human Knowledge: Its Scope and
Limits 8. The framework of Russell’s early epistemology consisted of an
analysis of knowledge in terms of justified true belief though it has been
suggested that he unintentionally anticipated Edmund Gettier’s objection to
this analysis, and an analysis of epistemic justification that combined
fallibilism with a weak empiricism and with a foundationalism that made room
for coherence. This framework was retained in An Inquiry and Human Knowledge,
but there were two sorts of changes that attenuated the foundationalist and
empiricist elements and accentuated the fallibilist element. First, the scope
of human knowledge was reduced. Russell had already replaced his earlier
Moorean consequentialism about values with subjectivism. Contrast “The Elements
of Ethics,” 0, with, e.g., Religion and Science, 5, or Human Society in Ethics
and Politics, 4. Consequently, what had been construed as self-evident
judgments of intrinsic value came to be regarded as non-cognitive expressions
of desire. In addition, Russell now reversed his earlier belief that deductive
inference can yield new knowledge. Second, the degree of justification
attainable in human knowledge was reduced at all levels. Regarding the
foundation of perceptual beliefs, Russell came to admit that the
object-knowledge “acquaintance with a sensedatum” was replaced by “noticing a
perceptive occurrence” in An Inquiry that provides the non-inferential
justification for a perceptual belief is buried under layers of
“interpretation” and unconscious inference in even the earliest stages of
perceptual processes. Regarding the superstructure of inferentially justified
beliefs, Russell concluded in Human Knowledge that unrestricted induction is
not generally truthpreserving anticipating Goodman’s “new riddle of induction”.
Consideration of the work of Reichenbach and Keynes on probability led him to
the conclusion that certain “postulates” are needed “to provide the antecedent
probabilities required to justify inductions,” and that the only possible
justification for believing these postulates lies, not in their self-evidence,
but in the resultant increase in the overall coherence of one’s total belief
system. In the end, Russell’s desire for certainty went unsatisfied, as he felt
himself forced to the conclusion that “all human knowledge is uncertain,
inexact, and partial. To this doctrine we have not found any limitation
whatever.” Russell’s strictly philosophical writings of 9 and later have
generally been less influential than his earlier writings. His influence was
eclipsed by that of logical positivism and ordinary language philosophy. He
approved of the logical positivists’ respect for logic and science, though he
disagreed with their metaphysical agnosticism. But his dislike of ordinary
language philosophy was visceral. In My Philosophical Development 9, he accused
its practitioners of abandoning the attempt to understand the world, “that
grave and important task which philosophy throughout the ages has hitherto
pursued.”
Russian nihilism, a form
of nihilism, a phenomenon mainly of Russia in the 1860s, which, in contrast to
the general cultural nihilism that Nietzsche later criticized in the 0s as a
“dead-end” devaluing of all values, was futureoriented and “instrumental,”
exalting possibility over actuality. Russian nihilists urged the
“annihilation” figurative and literal of the past and present, i.e., of realized
social and cultural values and of such values in process of realization, in the
name of the future, i.e., for the sake of social and cultural values yet to be
realized. Bakunin, as early as 1842, had stated the basic nihilist theme: “the
negation of what exists . . . for the benefit of the future which does not yet
exist.” The bestknown literary exemplar of nihilism in Russia is the character
Bazarov in Turgenev’s novel Fathers and Sons 1862. Its most articulate
spokesman was Dmitri Pisarev 184068, who shared Bazarov’s cultural
anti-Romanticism, philosophical anti-idealism, and unquestioned trust in the
power of natural science to solve social and moral problems. Pisarev
proclaimed, “It is precisely in the [spread-eagled, laboratory] frog that the
salvation . . . of the Russian people is to be found.” And he formulated what
may serve as the manifesto of Russian nihilism: “What can be broken should be
broken; what will stand the blow is fit to live; what breaks into smithereens
is rubbish; in any case, strike right and left, it will not and cannot do any
harm.”
Russian philosophy, the
philosophy produced by Russian thinkers, both in Russia and in the countries to
which they emigrated, from the mideighteenth century to the present. There was
no Renaissance in Russia, but in the early eighteenth century Peter the Great,
in opening a “window to the West,” opened Russia up to Western philosophical
influences. The beginnings of Russian speculation date from that period, in the
dialogues, fables, and poems of the anti-Enlightenment thinker Gregory
Skovoroda 172294 and in the social tracts, metaphysical treatises, and poems of
the Enlightenment thinker Alexander Radishchev 17491802. Until the last quarter
of the nineteenth century the most original and forceful Russian thinkers stood
outside the academy. Since then, both in Russia and in Western exile, a number
of the most important Russian philosophers
including Berdyaev and Lev Shestov 1866 8 have been
professors. The nineteenth-century thinkers, though educated, lacked
advanced degrees. The only professor
among them, Peter Lavrov 18230, taught mathematics and science rather than
philosophy during the 1850s. If we compare Russian philosophy to G. philosophy
of this period, with its galaxy of
professors Wolff, Kant, Fichte,
Schelling, Hegel, Dilthey the contrast
is sharp. However, if we compare Russian philosophy to English or philosophy, the contrast fades. No professors
of philosophy appear in the line from Francis Bacon through Hobbes, Locke,
Berkeley, Hume, Bentham, and J. S. Mill, to Spencer. And in France Montaigne,
Descartes, Pascal, Rousseau, and Comte were all non-professors. True to their
non-professional, even “amateur” status, Russian philosophers until the late
nineteenth century paid little attention to the more technical disciplines:
logic, epistemology, philosophy of language, and philosophy of science. They
focused instead on philosophical anthropology, ethics, social and political
philosophy, philosophy of history, and philosophy of religion. In Russia, more
than in any other Western cultural tradition, speculation, fiction, and poetry
have been linked. On the one hand, major novelists such as Tolstoy and
Dostoevsky, and major poets such as Pasternak and Brodsky, have engaged in
wide-ranging philosophical reflection. On the other hand, philosophers such as
Skovoroda, Alexei Khomyakov 180460, and Vladimir Solovyov 18530 were gifted
poets, while thinkers such as Herzen, Konstantin Leontyev 183, and the
anti-Leninist Marxist Alexander Bogdanov 18738 made their literary mark with
novels, short stories, and memoirs. Such Russian thinkers as Vasily Rozanov
18569 and Shestov, although they wrote no belles lettres, were celebrated in
literary circles for their sparkling essayistic and aphoristic styles. Certain
preoccupations of nineteenth-century Russian thinkers especially Pyotr Chaadaev 17941856 during the
1820s and 1830s, the Slavophiles and Westernizers during the 1840s and 1850s,
and the Populists during the 1860s and 1870s
might appear to be distinctive but in fact were not. The controversial
questions of Russia’s relation to Western Europe and of Russell’s paradox
Russian philosophy 805 805 Russia’s
“special path” to modernity have their counterparts in the reflections of
thinkers in Spain “Spain and Europe”, G.y the Sonderweg a term of which the Russian osobyi put’ is a
translation, and Poland “the Polish Question”. The content of Russian
philosophy may be characterized in general terms as tending toward utopianism,
maximalism, moralism, and soteriology. To take the last point first:
Hegelianism was received in Russia in the 1830s not only as an allembracing
philosophical system but also as a vehicle of secular salvation. In the 1860s
Darwinism was similarly received, as was Marxism in the 0s. Utopianism appears
at the historical and sociopolitical level in two of Solovyov’s characteristic
doctrines: his early “free theocracy,” in which the spiritual authority of the
Roman pope was to be united with the secular authority of the Russian tsar; and
his later ecumenical project of reuniting the Eastern Russian Orthodox and
Western Roman Catholic churches in a single “universal [vselenskaia] church”
that would also incorporate the “Protestant principle” of free philosophical
and theological inquiry. Maximalism appears at the individual and religious
level in Shestov’s claim that God, for whom alone “all things are possible,”
can cause what has happened not to have happened and, in particular, can
restore irrecoverable human loss, such as that associated with disease,
deformity, madness, and death. Maximalism and moralism are united at the cosmic
and “scientific-technological” level in Nikolai Fyodorov’s 18293 insistence on
the overriding moral obligation of all men “the sons” to join the common cause
of restoring life to “the fathers,” those who gave them life rather than, as
sanctioned by the “theory of progress,” pushing them, figuratively if not
literally, into the grave. Certain doctrinal emphases and assumptions link
Russian thinkers from widely separated points on the political and ideological
spectrum: 1 Russian philosophers were nearly unanimous in dismissing the
notorious CartesianHumean “problem of other minds” as a nonproblem. Their
convictions about human community and conciliarity sobornost’, whether
religious or secular, were too powerful to permit Russian thinkers to raise
serious doubts as to whether their moaning and bleeding neighbor was “really”
in pain. 2 Most Russian thinkers the
Westernizers were a partial exception
viewed key Western philosophical positions and formulations, from the
Socratic “know thyself” to the Cartesian cogito, as overly individualistic and
overly intellectualistic, as failing to take into account the wholeness of the
human person. 3 Both such anti-Marxists as Herzen with his “philosophy of the
act” and Fyodorov with his “projective” common task and the early Russian
Marxists were in agreement about the unacceptability of the “Western” dichotomy
between thought and action. But when they stressed the unity of theory and
practice, a key question remained: Who is to shape this unity? And what is its
form? The threadbare MarxistLeninist “philosophy” of the Stalin years paid lip
service to the freedom involved in forging such a unity. Stalin in fact imposed
crushing restraints upon both thought and action. Since 2, works by and about
the previously abused or neglected religious and speculative thinkers of
Russia’s past have been widely republished and eagerly discussed. This applies
to Fyodorov, Solovyov, Leontyev, Rozanov, Berdyaev, Shestov, and the Husserlian
Shpet, among others.
Ryle, Gilbert, English
analytic philosopher known especially for his contributions to the philosophy
of mind and his attacks on Cartesianism. His best-known work is the masterpiece
The Concept of Mind 9, an attack on what he calls “Cartesian dualism” and a
defense of a type of logical behaviorism. This dualism he dubs “the dogma of
the Ghost in the Machine,” the Machine being the body, which is physical and
publicly observable, and the Ghost being the mind conceived as a private or
secret arena in which episodes of sense perception, consciousness, and inner
perception take place. A person, then, is a combination of such a mind and a
body, with the mind operating the body through exercises of will called
“volitions.” Ryle’s attack on this doctrine is both sharply focused and
multifarious. He finds that it rests on a category mistake, namely,
assimilating statements about mental processes to the same category as
statements about physical processes. This is a mistake in the logic of mental
statements and mental concepts and leads to the mistaken metaphysical theory
that a person is composed of two separate and distinct though somehow related
entities, a mind and a body. It is true that statements about the physical are
statements about things and their changes. But statements about the mental are
not, and in particular are not about a thing called “the mind.” These two types
of statements do not belong to the same category. To show this, Ryle deploys a
variety of arguments, including arguments alleging the impossibility of causal
relations between mind and body and arguments alleging vicious infinite
regresses. To develop his positive view on the nature of mind, Ryle studies the
uses and hence the logic of mental terms and finds that mental statements tell
us that the person performs observable actions in certain ways and has a
disposition to perform other observable actions in specifiable circumstances.
For example, to do something intelligently is to do something physical in a
certain way and to adjust one’s behavior to the circumstances, not, as the
dogma of the Ghost in the Machine would have it, to perform two actions, one of
which is a mental action of thinking that eventually causes a separate physical
action. Ryle buttresses this position with many acute and subtle analyses of
the uses of mental terms. Much of Ryle’s other work concerns philosophical
methodology, sustaining the thesis which is the backbone of The Concept of Mind
that philosophical problems and doctrines often arise from conceptual
confusion, i.e., from mistakes about the logic of language. Important writings
in this vein include the influential article “Systematically Misleading
Expressions” and the book Dilemmas 4. Ryle was also interested in Grecian
philosophy throughout his life, and his last major work, Plato’s Progress, puts
forward novel hypotheses about changes in Plato’s views, the role of the
Academy, the purposes and uses of Plato’s dialogues, and Plato’s relations with
the rulers of Syracuse.
Saadiah Gaon 882942,
Jewish exegete, philosopher, liturgist, grammarian, and lexicographer. Born in
the Fayyum in Egypt, Saadiah wrote his first Hebrew dictionary by age twenty.
He removed to Tiberias, probably fleeing the backlash of his polemic against
the Karaite biblicist, anti-Talmudic sect. There he mastered the inductive
techniques of semantic analysis pioneered by Muslim MuÅtazilites in defending
their rationalistic monotheism and voluntaristic theodicy. He learned philologically
from the Masoretes and liturgical poets, and philosophically from the
MuÅtazilite-influenced Jewish metaphysician Daud al-Muqammif of Raqqa in Iraq,
and Isaac Israeli of Qayrawan in Tunisia, a Neoplatonizing physician, with whom
the young philosopher attempted a correspondence. But his sense of system,
evidenced in his pioneering chronology, prayerbook, and scheme of tropes, and
nurtured by Arabic versions of Plato but seemingly not much Aristotle, allowed
him to outgrow and outshine his mentors. He came to prominence by successfully
defending the traditional Hebrew calendar, using astronomical, mathematical,
and rabbinic arguments. Called to Baghdad, he became Gaon Hebrew, ‘Eminence’ or
head of the ancient Talmudic academy of Pumpedita, then nearly defunct. His
commentaries on rabbinic property law and his letters to Jewish communities as
far away as Spain refurbished the authority of the academy, but a controversy
with the Exilarch, secular head of Mesopotamian Jewry, led to his deposition
and six years in limbo, deprived of his judicial authority. He delved into
scientific cosmology, tr. many biblical books into Arabic with philosophic
commentaries and thematic introductions, and around 933 completed The Book of
Critically Chosen Beliefs and Convictions, the first Jewish philosophical
summa. Unusual among medieval works for a lengthy epistemological introduction,
its ten Arabic treatises defend and define creation, monotheism, human
obligation and virtue, theodicy, natural retribution, resurrection, immortality
and recompense, Israel’s redemption, and the good life. Saadiah argues that no
single good suffices for human happiness; each in isolation is destructive. The
Torah prepares the optimal blend of the appetitive and erotic, procreative,
civilizational, ascetic, political, intellectual, pious, and tranquil.
Following al-Rhazi d. 925 or 932, Saadiah argues that since destruction always
overcomes organization in this world, sufferings will always outweigh
pleasures; therefore as in rabbinic and MuÅtazilite theodicy God must be
assumed to right the balances in the hereafter. Indeed, justice is the object
of creation not simply that the
righteous be rewarded but that all should earn their deserved requital: the very
light that is sown for the righteous is the fire that torments the wicked. But
if requital and even recompense must be earned, this life is much more than an
anteroom. Authenticity becomes a value in itself: the innocent are not told
directly that their sufferings are a trial, or their testing would be invalid.
Only by enduring their sufferings without interference can they demonstrate the
qualities that make them worthy of the highest reward. Movingly reconciled with
the Exilarch, Saadiah ended his life as Gaon. His voluntarism, naturalism, and
rationalism laid philosophical foundations for Maimonides, and his inductive
exegesis became a cornerstone of critical hermeneutics.
Saint Petersburg paradox,
a puzzle about gambling that motivated the distinction between expected return
and expected utility. Daniel Bernoulli published it in a St. Petersburg journal
in 1738. It concerns a gamble like this: it pays $2 if heads appears on the
first toss of a coin, $4 if heads does not appear until the second toss, $8 if
heads does not appear until the third toss, and so on. The expected return from
the gamble is ½2 ! ¼4 ! 1 /88 ! . . . , or 1 ! 1 ! 1 ! ..., i.e., it is
infinite. But no one would pay much for the gamble. So it seems that expected
returns do not govern rational preferences. Bernoulli argued that expected
utilities govern rational preferences. He also held that the utility of wealth
is proportional to the log of the amount of wealth. Given his assumptions, the
gamble has finite 808 S 808 expected
utility, and should not be preferred to large sums of money. However, a
twentieth-century version of the paradox, attributed to Karl Menger,
reconstructs the gamble, putting utility payoffs in place of monetary payoffs,
so that the new gamble has infinite expected utility. Since no one would trade
much utility for the new gamble, it also seems that expected utilities do not
govern rational preferences. The resolution of the paradox is under
debate.
Saint-Simon, Comte de,
title of Claude-Henri de Rouvroy 17601825,
social reformer. An aristocrat by birth, he initially joined the ranks
of the enlightened and liberal bourgeoisie. His Newtonian Letters to an
Inhabitant of Geneva 1803 and Introduction to Scientific Works of the
Nineteenth Century 1808 championed Condorcet’s vision of scientific and technological
progress. With Auguste Comte, he shared a positivistic philosophy of history:
the triumph of science over metaphysics. Written in wartime, The Reorganization
of European Society 1814 urged the creation of a European parliamentary system
to secure peace and unity. Having moved from scientism to pacifism, Saint-Simon
moved further to industrialism. In 1817, under the influence of two theocratic
thinkers, de Maistre and Bonald, Saint-Simon turned away from classical
economic liberalism and repudiated laissez-faire capitalism. The Industrial
System 1820 drafts the program for a hierarchical state, a technocratic
society, and a planned economy. The industrial society of the future is based
on the principles of productivity and cooperation and led by a rational and
efficient class, the industrialists artists, scientists, and technicians. He
argued that the association of positivism with unselfishness, of techniques of
rational production with social solidarity and interdependency, would remedy
the plight of the poor. Industrialism prefigures socialism, and socialism paves
the way for the rule of the law of love, the eschatological age of The New
Christianity 1825. This utopian treatise, which reveals Saint-Simon’s
alternative to reactionary Catholicism and Protestant individualism, became the
Bible of the Saint-Simonians, a sectarian school of utopian socialists.
Same -- Sameness --
Griceian – One of Grice’s favourite essays ever was Wiggins’s “Sameness and
substance” -- Griceian différance, a
coinage deployed by Derrida in De la Grammatologie 7, where he defines
it as “an economic concept designating the production of differing/deferring.”
Différance is polysemic, but its key function is to name the prime condition
for the functioning of all language and thought: differing, the differentiation
of signs from each other that allows us to differentiate things from each
other. Deferring is the process by which signs refer to each other, thus
constituting the self-reference essential to language, without ever capturing
the being or presence that is the transcendent entity toward which it is aimed.
Without the concepts or idealities generated by the iteration of signs, we
could never identify a dog as a dog, could not perceive a dog or any other
thing as such. Perception presupposes language, which, in turn, presupposes the
ideality generated by the repetition of signs. Thus there can be no perceptual
origin for language; language depends upon an “original repetition,” a
deliberate oxymoron that Derrida employs to signal the impossibility of
conceiving an origin of language from within the linguistic framework in which
we find ourselves. Différance is the condition for language, and language is
the condition for experience: whatever meaning we may find in the world is
attributed to the differing/ deferring play of signifiers. The notion of
différance and the correlative thesis that meaning is language-dependent have
been appropriated by radical thinkers in the attempt to demonstrate that
political inequalities are grounded in nothing other than the conventions of
sign systems governing differing cultures.
Sanches, F. c.15511623,
Portuguese born philosopher and physician. Raised in southern France, he took
his medical degree at the of
Montpellier. After a decade of medical practice he was professor of philosophy
at the of Toulouse and later professor
of medicine there. His most important work, Quod nihil sciturThat Nothing Is
Known, 1581, is a classic of skeptical argumentation. Written at the same time
that his cousin, Montaigne, wrote the “Apology for Raimund Sebond,” it
devastatingly criticized the Aristotelian theory of knowledge. He began by
declaring that he did not even know if he knew nothing. Then he examined the
Aristotelian view that science consists of certain knowledge gained by
demonstrations from true definitions. First of all, we do not possess such
definitions, since all our definitions are just arbitrary names of things. The
Aristotelian theory of demonstration is useless, since in syllogistic reasoning
the conclusion has to be part of the evidence for the premises. E.g., how can
one know that all men are mortal unless one knows that Socrates is mortal?
Also, anything can be proven by syllogistic reasoning if one chooses the right
premises. This does not produce real knowledge. Further we cannot know anything
through its causes, since one would have to know the causes of the causes, and
the causes of these, ad infinitum. Sanches also attacked the Platonic theory of
knowledge, since mathematical knowledge is about ideal rather than real
objects. Mathematics is only hypothetical. Its relevance to experience is not
known. True science would consist of perfect knowledge of a thing. Each
particular would be understood in and by itself. Such knowledge can be attained
only by God. We cannot study objects one by one, since they are all
interrelated and interconnected. Our faculties are also not reliable enough.
Hence genuine knowledge cannot be attained by humans. What we can do, using
“scientific method” a term first used by Sanches, is gather careful empirical
information and make cautious judgments about it. His views were well known in
the seventeenth century, and may have inspired the “mitigated skepticism” of
Gassendi and others.
sanction, anything whose
function is to penalize or reward. It is useful to distinguish between social
sanctions, legal sanctions, internal sanctions, and religious sanctions. Social
sanctions are extralegal pressures exerted upon the agent by others. For
example, others might distrust us, ostracize us, or even physically attack us,
if we behave in certain ways. Legal sanctions include corporal punishment,
imprisonment, fines, withdrawal of the legal rights to run a business or to
leave the area, and other penalties. Internal sanctions may include not only
guilt feelings but also the sympathetic pleasures of helping others or the
gratified conscience of doing right. Divine sanctions, if there are any, are
rewards or punishments given to us by a god while we are alive or after we die.
There are important philosophical questions concerning sanctions. Should law be
defined as the rules the breaking of which elicits punishment by the state?
Could there be a moral duty to behave in a given way if there were no social
sanctions concerning such behavior? If not, then a conventionalist account of
moral duty seems unavoidable. And, to what extent does the combined effect of
external and internal sanctions make rational egoism or prudence or
self-interest coincide with morality?
Santayana, G.,
philosopher and writer. Born in Spain, he arrived in the United States as a
child, received his education at Harvard, and rose to professor of philosophy
there. He first came to prominence for his view, developed in The Sense of
Beauty 6, that beauty is objectified pleasure. His The Life of Reason 5 vols.,
5, a celebrated expression of his naturalistic vision, traces human creativity
in ordinary life, society, art, religion, and science. He denied that his
philosophy ever changed, but the mature expression of his thought, in
Skepticism and Animal Faith 3 and The Realms of Being 4 vols., 740, is
deliberately ontological and lacks the phenomenological emphasis of the earlier
work. Human beings, according to Santayana, are animals in a material world contingent
to the core. Reflection must take as its primary datum human action aimed at
eating and fleeing. The philosophy of animal faith consists of disentangling
the beliefs tacit in such actions and yields a realism concerning both the
objects of immediate consciousness and the objects of belief. Knowledge is true
belief rendered in symbolic terms. As symbolism, it constitutes the hauntingly
beautiful worlds of the senses, poetry, and religion; as knowledge, it guides
and is tested by successful action. Santayana had been taught by William James,
and his insistence on the primacy of action suggests a close similarity to the
views of Dewey. He is, nevertheless, not a pragmatist in any ordinary sense: he
views nature as the fully formed arena of human activity and experience as a
flow of isolated, private sentience in this alien world. His deepest sympathy
is with Aristotle, though he agrees with Plato about the mind-independent
existence of Forms and with Schopenhauer about the dimness of human prospects.
His mature four-realm ontology turns on the distinction between essence and
matter. Essences are forms of definiteness. They are infinite in number and
encompass everything possible. Their eternity makes them causally
inefficacious: as possibilities, they cannot accomplish their own
actualization. Matter, a surd and formless force, generates the physical
universe by selecting essences for embodiment. Truth is the realm of being
created by the intersection of matter and form: it is the eternal record of
essences that have been, are being, and will be given actuality in the history
of the world. Spirit or consciousness cannot be reduced to the motions of the
physical organism that give rise to it. It is constituted by a sequence of acts
or intuitions whose objects are essences but whose time-spanning, synthetic
nature renders them impotent. Organic selectivity is the source of values.
Accordingly, the good of each organism is a function of its nature. Santayana
simply accepts the fact that some of these goods are incommensurable and the
tragic reality that they may be incompatible, as well. Under favorable
circumstances, a life of reason or of maximal harmonized satisfactions is
possible for a while. The finest achievement of human beings, however, is the
spiritual life in which we overcome animal partiality and thus all valuation in
order to enjoy the intuition of eternal essences. Santayana identifies such
spirituality with the best that religion and sound philosophy can offer. It
does not help us escape finitude and death, but enables us in this short life
to transcend care and to intuit the eternal. Santayana’s exquisite vision has
gained him many admirers but few followers. His system is a self-consistent and
sophisticated synthesis of elements, such as materialism and Platonism, that
have hitherto been thought impossible to reconcile. His masterful writing makes
his books instructive and pleasurable, even if many of his characteristic views
engender resistance among philosophers.
Sapir-Whorf hypothesis,
broadly, the claim that one’s perception, thought, and behavior are influenced
by one’s language. The hypothesis was named after Benjamin Lee Whorf 7 1 and
his teacher Edward Sapir 4 9. We may discern different versions of this claim
by distinguishing degrees of linguistic influence, the highest of which is
complete and unalterable determination of the fundamental structures of
perception, thought, and behavior. In the most radical form, the hypothesis
says that one’s reality is constructed by one’s language and that differently
structured languages give rise to different realities, which are
incommensurable.
Sartre, J.-P. philosopher
and writer, the leading advocate of existentialism during the years following
World War II. The heart of his philosophy was the precious notion of freedom
and its concomitant sense of personal responsibility. He insisted, in an
interview a few years before his death, that he never ceased to believe that
“in the end one is always responsible for what is made of one,” only a slight
revision of his earlier, bolder slogan, “man makes himself.” To be sure, as a
student of Hegel, Marx, Husserl, and Heidegger
and because of his own physical frailty and the tragedies of the war Sartre had to be well aware of the many
constraints and obstacles to human freedom, but as a Cartesian, he never
deviated from Descartes’s classical portrait of human consciousness as free and
distinct from the physical universe it inhabits. One is never free of one’s
“situation,” Sartre tells us, though one is always free to deny “negate” that
situation and to try to change it. To be human, to be conscious, is to be free
to imagine, free to choose, and responsible for one’s lot in life. As a
student, Sartre was fascinated by Husserl’s new philosophical method, phenomenology.
His first essays were direct responses to Husserl and applications of the
phenomenological method. His essay on The Imagination in 6 established the
groundwork for much of what was to follow: the celebration of our remarkable
freedom to imagine the world other than it is and following Kant the way that
this ability informs all of our experience. In The Transcendence of the Ego 7
he reconsidered Husserl’s central idea of a “phenomenological reduction” the
idea of examining the essential structures of consciousness as such and argued
following Heidegger that one cannot examine consciousness without at the same
time recognizing the reality of actual objects in the world. In other words,
there can be no such “reduction.” In his novel Nausea 8, Sartre made this point
in a protracted example: his bored and often nauseated narrator confronts a
gnarled chestnut tree in the park and recognizes with a visceral shock that its
presence is simply given and utterly irreducible. In The Transcendence of the
Ego Sartre also reconsiders the notion of the self, which Husserl and so many
earlier philosophers had identified with consciousness. But the self, Sartre
argues, is not “in” consciousness, much less identical to it. The self is out
there “in the world, like the self of another.” In other words, the self is an
ongoing project in the world with other people; it is not simply self-awareness
or self-consciousness as such “I think, therefore I am”. This separation of
self and consciousness and the rejection of the self as simply
self-consciousness provide the framework for Sartre’s greatest philosophical
treatise, L’être et le néant Being and Nothingness, 3. Its structure is
unabashedly Cartesian, consciousness “being-for-itself” or pour soi on the one
side, the existence of mere things “being-in-itself” or en soi on the other.
The phraseology comes from Hegel. But Sartre does not fall into the Cartesian
trap of designating these two types of being as separate “substances.” Instead,
Sartre describes consciousness as “nothing’
“not a thing” but an activity, “a wind blowing from nowhere toward the
world.” Sartre often resorts to visceral metaphors when developing this theme
e.g., “a worm coiled in the heart of being”, but much of what he is arguing is
familiar to philosophical readers in the more metaphor-free work of Kant, who
also warned against the follies “paralogisms” of understanding consciousness as
itself a possible object of consciousness rather than as the activity of
constituting the objects of consciousness. As the lens of a camera can never
see itself and in a mirror only sees a
reflection of itself consciousness can
never view itself as consciousness and is only aware of itself “for itself”
through its experience of objects. Ontologically, one might think of “nothingness”
as “no-thing-ness,” a much less outrageous suggestion than those that would
make it an odd sort of a thing. It is through the nothingness of consciousness
and its activities that negation comes into the world, our ability to imagine
the world other than it is and the inescapable necessity of imagining ourselves
other than we seem to be. And because consciousness is nothingness, it is not
subject to the rules of causality. Central to the argument of L’être et le
néant and Sartre’s insistence on the primacy of human freedom is his insistence
that consciousness cannot be understood in causal terms. It is always
self-determining and, as such, “it always is what it is not, and is not what it
is” a playful paradox that refers to the
fact that we are always in the process of choosing. Consciousness is “nothing,”
but the self is always on its way to being something. Throughout our lives we
accumulate a body of facts that are true of us
our “facticity” but during our
lives we remain free to envision new possibilities, to reform ourselves and to
reinterpret our facticity in the light of new projects and ambitions our “transcendence.” This indeterminacy means
that we can never be anything, and when we try to establish ourselves as
something particular whether a social
role policeman, waiter or a certain character shy, intellectual, cowardly we are in “bad faith.” Bad faith is
erroneously viewing ourselves as something fixed and settled Sartre utterly
rejects Freud and his theory of the unconscious determination of our
personalities and behavior, but it is also bad faith to view oneself as a being
of infinite possibilities and ignore the always restrictive facts and
circumstances within which all choices must be made. On the one hand, we are
always trying to define ourselves; on the other hand we are always free to
break away from what we are, and always responsible for what we have made of
ourselves. But there is no easy resolution or “balance” between facticity and
freedom, rather a kind of dialectic or tension. The result is our frustrated
desire to be God, to be both in-itself and for-itself. But this is not so much
blasphemy as an expression of despair, a form of ontological original sin, the
impossibility of being both free and what we want to be. Life for Sartre is yet
more complicated. There is a third basic ontological category, on a par with
the being-in-itself and being-for-itself and not derivative of them. He calls
it “being-for-others.” To say that it is not derivative is to insist that our knowledge
of others is not inferred, e.g. by some argument by analogy, from the behavior
of others, and we ourselves are not wholly constituted by our
self-determinations and the facts about us. Sartre gives us a brutal but
familiar everyday example of our experience of being-for-others in what he
calls “the look” le regard. Someone catches us “in the act” of doing something
humiliating, and we find ourselves defining ourselves probably also resisting
that definition in their terms. In his Saint Genet 3, Sartre describes such a
conversion of the ten-year-old Jean Genet into a thief. So, too, we tend to
“catch” one another in the judgments we make and define one another in terms
that are often unflattering. But these judgments become an essential and
ineluctible ingredient in our sense of ourselves, and they too lead to
conflicts indeed, conflicts so basic and so frustrating that in his play Huis
clos No Exit, 3 Sartre has one of his characters utter the famous line, “Hell
is other people.” In his later works, notably his Critique of Dialectical
Reason 859, Sartre turned increasingly to politics and, in particular, toward a
defense of Marxism on existentialist principles. This entailed rejecting
materialist determinism, but it also required a new sense of solidarity or what
Sartre had wistfully called, following Heidegger, Mitsein or “being with
others”. Thus in his later work he struggled to find a way of overcoming the
conflict and insularity or the rather “bourgeois” consciousness he had
described in Being and Nothingness. Not surprisingly given his constant
political activities he found it in revolutionary engagement. Consonant with
his rejection of bourgeois selfhood, Sartre turned down the 4 Nobel prize for
literature.
Satisfactoriness-condition,
a state of affairs or “way things are,” most commonly referred to in relation
to something that implies or is implied by it. Let p, q, and r be schematic
letters for declarative sentences; and let P, Q, and R be corresponding
nominalizations; e.g., if p is ‘snow is white’, then P would be ‘snow’s being
white’. P can be a necessary or sufficient condition of Q in any of several
senses. In the weakest sense P is a sufficient condition of Q iff if and only
if: if p then q or if P is actual then Q is actual where the conditional is to be read as
“material,” as amounting merely to not-p & not-q. At the same time Q is a
necessary condition of P iff: if not-q then not-p. It follows that P is a
sufficient condition of Q iff Q is a necessary condition of P. Stronger senses
of sufficiency and of necessity are definable, in terms of this basic sense, as
follows: P is nomologically sufficient necessary for Q iff it follows from the
laws of nature, but not without them, that if p then q that if q then p. P is
alethically or metaphysically sufficient necessary for Q iff it is alethically
or metaphysically necessary that if p then q that if q then p. However, it is
perhaps most common of all to interpret conditions in terms of subjunctive
conditionals, in such a way that P is a sufficient condition of Q iff P would
not occur unless Q occurred, or: if P should occur, Q would; and P is a
necessary condition of Q iff Q would not occur unless P occurred, or: if Q
should occur, P would. -- satisfaction,
an auxiliary semantic notion introduced by Tarski in order to give a recursive
definition of truth for languages containing quantifiers. Intuitively, the
satisfaction relation holds between formulas containing free variables such as
‘Buildingx & Tallx’ and objects or sequences of objects such as the Empire
State Building if and only if the formula “holds of” or “applies to” the
objects. Thus, ‘Buildingx & Tallx’, is satisfied by all and only tall
buildings, and ‘-Tallx1 & Tallerx1, x2’ is satisfied by any pair of objects
in which the first object corresponding to ‘x1’ is not tall, but nonetheless
taller than the second corresponding to ‘x2’. Satisfaction is needed when
defining truth for languages with sentences built from formulas containing free
variables, because the notions of truth and falsity do not apply to these
“open” formulas. Thus, we cannot characterize the truth of the sentences ‘Dx
Buildingx & Tallx’ ‘Some building is tall’ in terms of the truth or falsity
of the open formula ‘Buildingx & Tallx’, since the latter is neither true nor
false. But note that the sentence is true if and only if the formula is
satisfied by some object. Since we can give a recursive definition of the
notion of satisfaction for possibly open formulas, this enables us to use this
auxiliary notion in defining truth. -- satisfiable,
having a common model, a structure in which all the sentences in the set are
true; said of a set of sentences. In modern logic, satisfiability is the
semantic analogue of the syntactic, proof-theoretic notion of consistency, the
unprovability of any explicit contradiction. The completeness theorem for
first-order logic, that all valid sentences are provable, can be formulated in
terms of satisfiability: syntactic consistency implies satisfiability. This
theorem does not necessarily hold for extensions of first-order logic. For any
sound proof system for secondorder logic there will be an unsatisfiable set of
sentences without there being a formal derivation of a contradiction from the
set. This follows from Gödel’s incompleteness theorem. One of the central
results of model theory for first-order logic concerns satisfiability: the
compactness theorem, due to Gödel in 6, says that if every finite subset of a
set of sentences is satisfiable the set itself is satisfiable. It follows immediately
from his completeness theorem for first-order logic, and gives a powerful
method to prove the consistency of a set of sentences.
satisfice, to choose or
do the good enough rather than the most or the best. ‘Satisfice’, an obsolete
variant of ‘satisfy’, has been adopted by economist Herbert Simon and others to
designate nonoptimizing choice or action. According to some economists,
limitations of time or information may make it impossible or inadvisable for an
individual, firm, or state body to attempt to maximize pleasure, profits,
market share, revenues, or some other desired result, and satisficing with
respect to such results is then said to be rational, albeit less than ideally
rational. Although many orthodox economists think that choice can and always
should be conceived in maximizing or optimizing terms, satisficing models have
been proposed in economics, evolutionary biology, and philosophy. Biologists
have sometimes conceived evolutionary change as largely consisting of “good
enough” or satisficing adaptations to environmental pressures rather than as
proceeding through optimal adjustments to such pressures, but in philosophy,
the most frequent recent use of the idea of satisficing has been in ethics and
rational choice theory. Economists typically regard satisficing as acceptable
only where there are unwanted constraints on decision making; but it is also
possible to see satisficing as entirely acceptable in itself, and in the field
of ethics, it has recently been argued that there may be nothing remiss about
moral satisficing, e.g., giving a good amount to charity, but less than one
could give. It is possible to formulate satisficing forms of utilitarianism on
which actions are morally right even if they contribute merely positively
and/or in some large way, rather than maximally, to overall net human
happiness. Bentham’s original formulation of the principle of utility and
Popper’s negative utilitarianism are both examples of satisficing
utilitarianism in this sense and it
should be noted that satisficing utilitarianism has the putative advantage over
optimizing forms of allowing for supererogatory degrees of moral excellence.
Moreover, any moral view that treats moral satisficing as permissible makes
room for moral supererogation in cases where one optimally goes beyond the
merely acceptable. But since moral satisficing is less than optimal moral
behavior, but may be more meritorious than certain behavior that in the same
circumstances would be merely permissible, some moral satisficing may actually
count as supererogatory. In recent work on rational individual choice, some
philosophers have argued that satisficing may often be acceptable in itself,
rather than merely second-best. Even Simon allows that an entrepreneur may
simply seek a satisfactory return on investment or share of the market, rather
than a maximum under one of these headings. But a number of philosophers have
made the further claim that we may sometimes, without irrationality, turn down
the readily available better in the light of the goodness and sufficiency of
what we already have or are enjoying. Independently of the costs of taking a
second dessert, a person may be entirely satisfied with what she has eaten and,
though willing to admit she would enjoy that extra dessert, turn it down,
saying “I’m just fine as I am.” Whether such examples really involve an
acceptable rejection of the momentarily better for the good enough has been
disputed. However, some philosophers have gone on to say, even more strongly,
that satisficing can sometimes be rationally required and optimizing rationally
unacceptable. To keep on seeking pleasure from food or sex without ever being
thoroughly satisfied with what one has enjoyed can seem compulsive and as such
less than rational. If one is truly rational about such goods, one isn’t
insatiable: at some point one has had enough and doesn’t want more, even though
one could obtain further pleasure. The idea that satisficing is sometimes a
requirement of practical reason is reminiscent of Aristotle’s view that
moderation is inherently reasonable
rather than just a necessary means to later enjoyments and the avoidance
of later pain or illness, which is the way the Epicureans conceived moderation.
But perhaps the greatest advocate of satisficing is Plato, who argues in the
Philebus that there must be measure or limit to our desire for pleasure in
order for pleasure to count as a good thing for us. Insatiably to seek and
obtain pleasure from a given source is to gain nothing good from it. And
according to such a view, satisficing moderation is a necessary precondition of
human good and flourishing, rather than merely being a rational restraint on
the accumulation of independently conceived personal good or well-being.
Saussure, Ferdinand de,
founder of structuralism. His work in semiotics is a major influence on the
later development of structuralist
philosophy, as well as structural anthropology, structuralist literary
criticism, and modern semiology. He pursued studies in linguistics largely
under Georg Curtius at the of Leipzig,
along with such future Junggrammatiker neogrammarians as Leskien and Brugmann.
Following the publication of his important Mémoire sur le système primitif des
voyelles dans les langues indo-européenes 1879, Saussure left for Paris, where
he associated himself with the Société Linguistique and taught comparative
grammar. In 1, he returned to Switzerland to teach Sanskrit, comparative
grammar, and general linguistics at the
of Geneva. His major work, the Course in General Linguistics 6, was
assembled from students’ notes and his original lecture outlines after his
death. The Course in General Linguistics argued against the prevalent
historical and comparative philological approaches to language by advancing
what Saussure termed a scientific model for linguistics, one borrowed in part
from Durkheim. Such a model would take the “social fact” of language la langue
as its object, and distinguish this from the variety of individual speech
events la parole, as well as from the collectivity of speech events and
grammatical rules that form the general historical body of language as such le
langage. Thus, by separating out the unique and accidental elements of
practiced speech, Saussure distinguished language la langue as the objective
set of linguistic elements and rules that, taken as a system, governs the
language use specific to a given community. It was the systematic coherency and
generality of language, so conceived, that inclined Saussure to approach
linguistics principally in terms of its static or synchronic dimension, rather
than its historical or diachronic dimension. For Saussure, the system of
language is a “treasury” or “depository” of signs, and the basic unit of the
linguistic sign is itself two-sided, having both a phonemic component “the
signifier” and a semantic component “the signified”. He terms the former the
“acoustical” or “sound” image which may,
in turn, be represented graphically, in writing
and the latter the “concept” or “meaning.” Saussure construes the
signifier to be a representation of linguistic sounds in the imagination or
memory, i.e., a “psychological phenomenon,” one that corresponds to a
specifiable range of material phonetic sounds. Its distinctive property
consists in its being readily differentiated from other signifiers in the
particular language. It is the function of each signifier, as a distinct
entity, to convey a particular meaning
or “signified” concept and this
is fixed purely by conventional association. While the relation between the
signifier and signified results in what Saussure terms the “positive” fact of
the sign, the sign ultimately derives its linguistic value its precise
descriptive determination from its position in the system of language as a
whole, i.e., within the paradigmatic and syntagmatic relations that
structurally and functionally differentiate it. Signifiers are differentially
identified; signifiers are arbitrarily associated with their respective
signified concepts; and signs assume the determination they do only through their
configuration within the system of language as a whole: these facts enabled
Saussure to claim that language is largely to be understood as a closed formal
system of differences, and that the study of language would be principally
governed by its autonomous structural determinations. So conceived, linguistics
would be but a part of the study of social sign systems in general, namely, the
broader science of what Saussure termed semiology. Saussure’s insights would be
taken up by the subsequent Geneva, Prague, and Copenhagen schools of
linguistics and by the Russian formalists, and would be further developed by
the structuralists in France and elsewhere, as well as by recent semiological
approaches to literary criticism, social anthropology, and psychoanalysis.
scepticism: For some reason, Grice was irritated by Wood’s
sobriquet of Russell as a “passionate sceptic”: ‘an oxymoron.” The most
specific essay by Grice on this is an essay he kept after many years, that he
delivered back in the day at Oxford, entitled, “Scepticism and common sense.”
Both were traditional topics at Oxford at the time. Typically, as in the
Oxonian manner, he chose two authors, New-World’s Malcolm’s treatment of
Old-World Moore, and brings in Austin’s ‘ordinary-language’ into the bargain.
He also brings in his own obsession with what an emissor communicates. In this
case, the “p” is the philosopher’s sceptical proposition, such as “That pillar
box is red.” Grice thinks ‘dogmatic’ is the opposite of ‘sceptic,’ and he is
right! Liddell and Scott have “δόγμα,” from “δοκέω,” and which they
render as “that which seems to one, opinion or belief;” Pl.R.538c; “δ. πόλεως
κοινόν;” esp. of philosophical doctrines, Epicur.Nat.14.7; “notion,”
Pl.Tht.158d; “decision, judgement,” Pl. Lg.926d; (pl.); public decree,
ordinance, esp. of Roman
Senatus-consulta, “δ. συγκλήτου” “δ. τῆς
βουλῆς” So note that there is nothing ‘dogmatic’ about ‘dogma,’ as it derives
from ‘dokeo,’ and is rendered as ‘that which seems to one.’ So the keyword
should be later Grecian, and in the adjectival ‘dogmatic.’ Liddell and Scott
have “δογματικός,” which they render as “of or for doctrines, didactic,
[διάλογοι] Quint.Inst.2.15.26, and “of persons, δ. ἰατροί,” “physicians who go
by general principles,” opp. “ἐμπειρικοί and μεθοδικοί,” Dsc.Ther.Praef.,
Gal.1.65; in Philosophy, S.E.M.7.1, D.L.9.70, etc.; “δ. ὑπολήψεις” Id.9.83; “δ.
φιλοσοφία” S.E. P.1.4. Adv. “-κῶς” D.L.9.74, S.E.P.1.197: Comp. “-κώτερον”
Id.M. 6.4. Why is Grice
interested in scepticism. His initial concern, the one that Austin would
authorize, relates to ‘ordinary language.’ What if ‘ordinary language’ embraces
scepticism? What if it doesn’t? Strawso notes that the world of ordinary
language is a world of things, causes, and stuff. None of the good stuff for
the sceptic. what is Grice’s answer to the sceptic’s implicaturum? The
sceptic’s implicaturum is a topic that always fascinated Girce. While Grice
groups two essays as dealing with one single theme, strictly, only this or that
philosopher’s paradox (not all) may count as sceptical. This or that
philosopher’s paradox may well not be sceptical at all but rather dogmatic. In
fact, Grice defines philosophers paradox as anything repugnant to common sense,
shocking, or extravagant ‒ to Malcolms ears, that is! While it is,
strictly, slightly odd to quote this as a given date just because, by a stroke
of the pen, Grice writes that date in the Harvard volume, we will follow
his charming practice. This is vintage Grice. Grice always takes the
sceptics challenge seriously, as any serious philosopher should. Grices
takes both the sceptics explicatum and the scepticss implicaturum as
self-defeating, as a very affront to our idea of rationality, conversational or
other. V: Conversations with a sceptic: Can he be slightly more conversational
helpful? Hume’ sceptical attack is partial, and targeted only towards practical
reason, though. Yet, for Grice, reason is one. You cannot really attack
practical or buletic reason without attacking theoretical or doxastic reason.
There is such thing as a general rational acceptance, to use Grice’s term, that
the sceptic is getting at. Grice likes to play with the idea that ultimately
every syllogism is buletic or practical. If, say, a syllogism by Eddington
looks doxastic, that is because Eddington cares to omit the practical tail, as
Grice puts it. And Eddington is not even a philosopher, they say. Grice is here
concerned with a Cantabrigian topic popularised by Moore. As Grice
recollects, Some like Witters, but Moore’s my man. Unlike Cambridge
analysts such as Moore, Grice sees himself as a linguistic-turn Oxonian
analyst. So it is only natural that Grice would connect time-honoured
scepticism of Pyrrhos vintage, and common sense with ordinary language, so
mis-called, the elephant in Grices room. Lewis and Short have “σκέψις,” f. σκέπτομαι,
which they render as “viewing, perception by the senses, ἡ διὰ τῶν ὀμμάτων
ςκέψις, Pl. Phd. 83a; observation of auguries; also as examination,
speculation, consideration, τὸ εὕρημα πολλῆς σκέψιος; βραχείας ςκέψις; ϝέμειν
ςκέψις take thought of a thing; ἐνθεὶς τῇ τέχνῃ ςκέψις; ςκέψις ποιεῖσθαι;
ςκέψις προβέβληκας; ςκέψις λόγων; ςκέψις περί τινος inquiry
into, speculation on a thing; περί τι Id. Lg. 636d;ἐπὶ σκέψιν τινὸς ἐλθεῖν; speculation,
inquiry,ταῦτα ἐξωτερικωτέρας ἐστὶ σκέψεως; ἔξω τῆς νῦν ςκέψεως; οὐκ οἰκεῖα τῆς
παρούσης ςκέψις; also hesitation, doubt, esp. of the Sceptic or Pyrthonic
philosophers, AP 7. 576 (Jul.); the Sceptic philosophy, S. E. P. 1.5; οἱ ἀπὸ
τῆς ςκέψεως, the Sceptics, ib. 229. in politics, resolution, decree,
συνεδρίον Hdn. 4.3.9, cf. Poll. 6.178. If scepticism attacks common sense
and fails, Grice seems to be implicating, that ordinary language philosophy is
a good antidote to scepticism. Since what language other than ordinary language
does common sense speak? Well, strictly, common sense doesnt speak. The man in
the street does. Grice addresses this topic in a Mooreian way in a later essay,
also repr. in Studies, Moore and philosophers paradoxes, repr. in Studies.
As with his earlier Common sense and scepticism, Grice tackles Moores and
Malcolms claim that ordinary language, so-called, solves a few of philosophers
paradoxes. Philosopher is Grices witty way to generalise over your
common-or-garden, any, philosopher, especially of the type he found eccentric,
the sceptic included. Grice finds this or that problem in this overarching
Cantabrigian manoeuvre, as over-simplifying a pretty convoluted
terrain. While he cherishes Austins Some like Witters, but Moores MY man!
Grice finds Moore too Cantabrigian to his taste. While an Oxonian thoroughbred,
Grice is a bit like Austin, Some like Witters, but Moores my man, with this or
that caveat. Again, as with his treatment of Descartes or Locke, Grice is
hardly interested in finding out what Moore really means. He is a philosopher,
not a historian of philosophy, and he knows it. While Grice agrees with Austins
implicaturum that Moore goes well above Witters, if that is the expression
(even if some like him), we should find the Oxonian equivalent to Moore. Grice
would not Names Ryle, since he sees him, and his followers, almost every day.
There is something apostolic about Moore that Grice enjoys, which is just as
well, seeing that Moore is one of the twelve. Grice found it amusing that
the members of The Conversazione Society would still be nickNamesd apostles
when their number exceeded the initial 12. Grice spends some time exploring
what Malcolm, a follower of Witters, which does not help, as it were, has to
say about Moore in connection with that particularly Oxonian turn of phrase,
such as ordinary language is. For Malcolms Moore, a paradox by philosopher
[sic], including the sceptic, arises when philosopher [sic], including the
sceptic, fails to abide by the dictates of ordinary language. It might merit
some exploration if Moore’s defence of common sense is against: the sceptic may
be one, but also the idealist. Moore the realist, armed with ordinary language
attacks the idealists claim. The idealist is sceptical of the realists claim.
But empiricist idealism (Bradley) has at Oxford as good pedigree as empiricist
realism (Cook Wilson). Malcolm’s simplifications infuriate Grice, and ordinary
language has little to offer in the defense of common sense realism against
sceptical empiricist idealism. Surely the ordinary man says ridiculous, or
silly, as Russell prefers, things, such as Smith is lucky, Departed spirits
walk along this road on their way to Paradise, I know there are infinite stars,
and I wish I were Napoleon, or I wish that I had
been Napoleon, which does not mean that the utterer wishes that
he were like Napoleon, but that he wishes that he had lived
not in the his century but in the XVIIIth century. Grice is being specific
about this. It is true that an ordinary use of language, as Malcolm
suggests, cannot be self-contradictory unless the ordinary use of language is
defined by stipulation as not self-contradictory, in which case an appeal to
ordinary language becomes useless against this or that paradox by Philosopher.
I wish that I had been Napoleon seems to involve nothing but an ordinary use of
language by any standard but that of freedom from absurdity. I wish
that I had been Napoleon is not, as far as Grice can see, philosophical, but
something which may have been said and meant by numbers of ordinary
people. Yet, I wish that I had been Napoleon is open to the suspicion of
self-contradictoriness, absurdity, or some other kind of
meaninglessness. And in this context suspicion is all Grice needs. By
uttering I wish that I had been Napoleon U hardly means the same as he
would if he uttered I wish I were like Napoleon. I wish that I had been
Napoleon is suspiciously self-contradictory, absurd, or meaningless, if, as
uttered by an utterer in a century other than the XVIIIth century, say, the
utterer is understood as expressing the proposition that the utterer wishes
that he had lived in the XVIIIth century, and not in his century, in which case
he-1 wishes that he had not been him-1? But blame it on the
buletic. That Moore himself is not too happy with Malcolms criticism can
be witnessed by a cursory glimpse at hi reply to Malcolm. Grice is totally
against this view that Malcolm ascribes to Moore as a view that is too broad to
even claim to be true. Grices implicaturum is that Malcolm is appealing to
Oxonian turns of phrase, such as ordinary language, but not taking proper
Oxonian care in clarifying the nuances and stuff in dealing with, admittedly, a
non-Oxonian philosopher such as Moore. When dealing with Moore, Grice is not
necessarily concerned with scepticism. Time is unreal, e.g. is hardly a sceptic
utterance. Yet Grice lists it as one of Philosophers paradoxes. So, there are
various to consider here. Grice would start with common sense. That is what he
does when he reprints this essay in WOW, with his attending note in both the
preface and the Retrospective epilogue on how he organizes the themes and
strands. Common sense is one keyword there, with its attending realism.
Scepticism is another, with its attending empiricist idealism. It is intriguing
that in the first two essays opening Grices explorations in semantics and metaphysics
it seems its Malcolm, rather than the dryer Moore, who interests Grice most.
While he would provide exegeses of this or that dictum by Moore, and indeed,
Moore’s response to Malcolm, Grice seems to be more concerned with applications
of his own views. Notably in Philosophers paradoxes. The fatal objection Grice
finds for the paradox propounder (not necessarily a sceptic, although a sceptic
may be one of the paradox propounders) significantly rests on Grices reductive
analysis of meaning that as ascribed to
this or that utterer U. Grice elaborates on circumstances that hell later take
up in the Retrospective epilogue. I find myself not understanding what I mean
is dubiously acceptable. If meaning, Grice claims, is about an utterer U
intending to get his addressee A to believe that U ψ-s that p, U must think
there is a good chance that A will recognise what he is supposed to believe,
by, perhaps, being aware of the Us practice or by a supplementary explanation
which might come from U. In which case, U should not be meaning what Malcolm
claims U might mean. No utterer should intend his addressee to believe what is
conceptually impossible, or incoherent, or blatantly false (Charles Is
decapitation willed Charles Is death.), unless you are Queen in Through the
Looking Glass. I believe five impossible things before breakfast, and I hope
youll soon get the proper training to follow suit. Cf. Tertulian, Credo, quia
absurdum est. Admittedly, Grice edits the Philosophers paradoxes essay. It is
only Grices final objection which is repr. in WOW, even if he provides a good
detailed summary of the previous sections. Grice appeals to Moore on later
occasions. In Causal theory, Grice lists, as a third philosophical
mistake, the opinion by Malcolm that Moore did not know how to use knowin a
sentence. Grice brings up the same example again in Prolegomena. The use of
factive know of Moore may well be a misuse. While at Madison, Wisconsin, Moore
lectures at a hall eccentrically-built with indirect lighting simulating sun
rays, Moore infamously utters, I know that there is a window behind that
curtain, when there is not. But it is not the factiveness Grice is aiming at,
but the otiosity Malcolm misdescribes in the true, if baffling, I know that I
have two hands. In Retrospective epilogue, Grice uses M to abbreviate Moore’s
fairy godmother – along with G (Grice), A (Austin), R (Ryle) and Q (Quine)! One
simple way to approach Grices quandary with Malcolm’s quandary with Moore is
then to focus on know. How can Malcolm claim that Moore is guilty of misusing
know? The most extensive exploration by Grice on know is in Grices third James
lecture (but cf. his seminar on Knowledge and belief, and his remarks on some
of our beliefs needing to be true, in Meaning revisited. The examinee
knows that the battle of Waterloo was fought in 1815. Nothing odd about that,
nor about Moores uttering I know that these are my hands. Grice is perhaps the
only one of the Oxonian philosophers of Austins play group who took common
sense realsim so seriously, if only to crticise Malcoms zeal with it. For
Grice, common-sense realism = ordinary language, whereas for the typical
Austinian, ordinary language = the language of the man in the street. Back at
Oxford, Grice uses Malcolm to contest the usual criticism that Oxford
ordinary-language philosophers defend common-sense realist assumptions just
because the way non-common-sense realist philosopher’s talk is not ordinary
language, and even at Oxford. Cf. Flews reference to Joness philosophical
verbal rubbish in using self as a noun. Grice is infuriated by all this unclear
chatter, and chooses Malcolms mistreatment of Moore as an example. Grice is
possibly fearful to consider Austins claims directly! In later essays, such as
‘the learned’ and ‘the lay,’ Grice goes back to the topic criticising now the
scientists jargon as an affront to the ordinary language of the layman that
Grice qua philosopher defends. scepticism, in the most common sense,
the refusal to grant that there is any knowledge or justification. Skepticism
can be either partial or total, either practical or theoretical, and, if
theoretical, either moderate or radical, and either of knowledge or of
justification. Skepticism is partial iff if and only if it is restricted to
particular fields of beliefs or propositions, and total iff not thus
restricted. And if partial, it may be highly restricted, as is the skepticism
for which religion is only opium, or much more general, as when not only is
religion called opium, but also history bunk and metaphysics meaningless.
Skepticism is practical iff it is an attitude of deliberately withholding both
belief and disbelief, accompanied perhaps but not necessarily by commitment to
a recommendation for people generally, that they do likewise. Practical
skepticism can of course be either total or partial, and if partial it can be
more or less general. Skepticism is theoretical iff it is a commitment to the
belief that there is no knowledge justified belief of a certain kind or of
certain kinds. Such theoretical skepticism comes in several varieties. It is
moderate and total iff it holds that there is no certain superknowledge
superjustified belief whatsoever, not even in logic or mathematics, nor through
introspection of one’s present experience. It is radical and total iff it holds
that there isn’t even any ordinary knowledge justified belief at all. It is
moderate and partial, on the other hand, iff it holds that there is no certain
superknowledge superjustified belief of a certain specific kind K or of certain
specific kinds K1, . . . , Kn less than the totality of such kinds. It is
radical and partial, finally, iff it holds that there isn’t even any ordinary
knowledge justified belief at all of that kind K or of those kinds K1, . . . ,
Kn. Grecian skepticism can be traced back to Socrates’ epistemic modesty.
Suppressed by the prolific theoretical virtuosity of Plato and Aristotle, such
modesty reasserted itself in the skepticism of the Academy led by Arcesilaus
and later by Carneades. In this period began a long controversy pitting
Academic Skeptics against the Stoics Zeno and later Chrysippus, and their
followers. Prolonged controversy, sometimes heated, softened the competing
views, but before agreement congealed Anesidemus broke with the Academy and
reclaimed the arguments and tradition of Pyrrho, who wrote nothing, but whose
Skeptic teachings had been preserved by a student, Timon in the third century
B.C.. After enduring more than two centuries, neoPyrrhonism was summarized,
c.200 A.D., by Sextus Empiricus Outlines of Pyrrhonism and Adversus
mathematicos. Skepticism thus ended as a school, but as a philosophical
tradition it has been influential long after that, and is so even now. It has
influenced strongly not only Cicero Academica and De natura deorum, St. Augustine
Contra academicos, and Montaigne “Apology for Raimund Sebond”, but also the
great historical philosophers of the Western tradition, from Descartes through
Hegel. Both on the Continent and in the Anglophone sphere a new wave of
skepticism has built for decades, with logical positivism, deconstructionism,
historicism, neopragmatism, and relativism, and the writings of Foucault
knowledge as a mask of power, Derrida deconstruction, Quine indeterminacy and
eliminativism, Kuhn incommensurability, and Rorty solidarity over objectivity,
edification over inquiry. At the same time a rising tide of books and articles
continues other philosophical traditions in metaphysics, epistemology, ethics,
etc. It is interesting to compare the cognitive disengagement recommended by
practical skepticism with the affective disengagement dear to stoicism
especially in light of the epistemological controversies that long divided
Academic Skepticism from the Stoa, giving rise to a rivalry dominant in
Hellenistic philosophy. If believing and favoring are positive, with
disbelieving and disfavoring their respective negative counterparts, then the
magnitude of our happiness positive or unhappiness negative over a given matter
is determined by the product of our belief/disbelief and our
favoring/disfavoring with regard to that same matter. The fear of unhappiness
may lead one stoically to disengage from affective engagement, on either side
of any matter that escapes one’s total control. And this is a kind of practical
affective “skepticism.” Similarly, if believing and truth are positive, with
disbelieving and falsity their respective negative counterparts, then the
magnitude of our correctness positive or error negative over a given matter is
determined by the product of our belief/disbelief and the truth/falsity with
regard to that same matter where the positive or negative magnitude of the
truth or falsity at issue may be determined by some measure of “theoretical
importance,” though alternatively one could just assign all truths a value of
!1 and all falsehoods a value of †1. The fear of error may lead one skeptically
to disengage from cognitive engagement, on either side of any matter that
involves risk of error. And this is “practical cognitive skepticism.” We wish
to attain happiness and avoid unhappiness. This leads to the disengagement of
the stoic. We wish to attain the truth and avoid error. This leads to the
disengagement of the skeptic, the practical skeptic. Each opts for a
conservative policy, but one that is surely optional, given just the reasoning
indicated. For in avoiding unhappiness the stoic also forfeits a corresponding
possibility of happiness. And in avoiding error the skeptic also forfeits a
corresponding possibility to grasp a truth. These twin policies appeal to conservatism
in our nature, and will reasonably prevail in the lives of those committed to
avoiding risk as a paramount objective. For this very desire must then be given
its due, if we judge it rational. Skepticism is instrumental in the birth of
modern epistemology, and modern philosophy, at the hands of Descartes, whose
skepticism is methodological but sophisticated and well informed by that of the
ancients. Skepticism is also a main force, perhaps the main force, in the broad
sweep of Western philosophy from Descartes through Hegel. Though preeminent in
the history of our subject, skepticism since then has suffered decades of
neglect, and only in recent years has reclaimed much attention and even
applause. Some recent influential discussions go so far as to grant that we do
not know we are not dreaming. But they also insist one can still know when
there is a fire before one. The key is to analyze knowledge as a kind of
appropriate responsiveness to its object truth: what is required is that the
subject “track” through his belief the truth of what he believes. S tracks the
truth of P iff: S would not believe P if P were false. Such an analysis of
tracking, when conjoined with the view of knowledge as tracking, enables one to
explain how one can know about the fire even if for all one knows it is just a
dream. The crucial fact here is that even if P logically entails Q, one may
still be able to track the truth of P though unable to track the truth of Q.
Nozick, Philosophical Explanations, 1. Many problems arise in the literature on
this approach. One that seems especially troubling is that though it enables us
to understand how contingent knowledge of our surroundings is possible, the
tracking account falls short of enabling an explanation of how such knowledge
on our part is actual. To explain how one knows that there is a fire before one
F, according to the tracking account one presumably would invoke one’s tracking
the truth of F. But this leads deductively almost immediately to the claim that
one is not dreaming: Not D. And this is not something one can know, according
to the tracking account. So how is one to explain one’s justification for
making that claim? Most troubling of all here is the fact that one is now
cornered by the tracking account into making combinations of claims of the
following form: I am quite sure that p, but I have no knowledge at all as to
whether p. And this seems incoherent. A Cartesian dream argument that has had
much play in recent discussions of skepticism is made explicit by Barry Stroud,
The Significance of Philosophical Scepticism, 4 as follows. One knows that if
one knows F then one is not dreaming, in which case if one really knows F then
one must know one is not dreaming. However, one does not know one is not
dreaming. So one does not know F. Q.E.D. And why does one fail to know one is
not dreaming? Because in order to know it one would need to know that one has
passed some test, some empirical procedure to determine whether one is
dreaming. But any such supposed test
say, pinching oneself could just
be part of a dream, and dreaming one passes the test would not suffice to show
one was not dreaming. However, might one not actually be witnessing the fire,
and passing the test and be doing this
in wakeful life, not in a dream and
would that not be compatible with one’s knowing of the fire and of one’s
wakefulness? Not so, according to the argument, since in order to know of the
fire one needs prior knowledge of one’s wakefulness. But in order to know of
one’s wakefulness one needs prior knowledge of the results of the test
procedure. But this in turn requires prior knowledge that one is awake and not
dreaming. And we have a vicious circle. We might well hold that it is possible
to know one is not dreaming even in the absence of any positive test result, or
at most in conjunction with coordinate not prior knowledge of such a positive
indication. How in that case would one know of one’s wakefulness? Perhaps one
would know it by believing it through the exercise of a reliable faculty.
Perhaps one would know it through its coherence with the rest of one’s
comprehensive and coherent body of beliefs. Perhaps both. But, it may be urged,
if these are the ways one might know of one’s wakefulness, does not this answer
commit us to a theory of the form of A below? A The proposition that p is
something one knows believes justifiably if and only if one satisfies
conditions C with respect to it. And if so, are we not caught in a vicious
circle by the question as to how we know
what justifies us in believing A
itself? This is far from obvious, since the requirement that we must submit to
some test procedure for wakefulness and know ourselves to test positively,
before we can know ourselves to be awake, is itself a requirement that seems to
lead equally to a principle such as A. At least it is not evident why the
proposal of the externalist or of the coherentist as to how we know we are
awake should be any more closely related to a general principle like A than is
the foundationalist? notion that in order to know we are awake we need
epistemically prior knowledge that we test positive in a way that does not
presuppose already acquired knowledge of the external world. The problem of how
to justify the likes of A is a descendant of the infamous “problem of the
criterion,” reclaimed in the sixteenth century and again in this century by
Chisholm, Theory of Knowledge, 6, 7, and 8 but much used already by the
Skeptics of antiquity under the title of the diallelus. About explanations of
our knowledge or justification in general of the form indicated by A, we are
told that they are inadequate in a way revealed by examples like the following.
Suppose we want to know how we know anything at all about the external world,
and part of the answer is that we know the location of our neighbor by knowing
the location of her car in her driveway. Surely this would be at best the
beginning of an answer that might be satisfactory in the end if recursive,
e.g., but as it stands it cannot be satisfactory without supplementation. The
objection here is based on a comparison between two appeals: the appeal of a
theorist of knowledge to a principle like A in the course of explaining our
knowledge or justification in general, on one side; and the appeal to the car’s
location in explaining our knowledge of facts about the external world, on the
other side. This comparison is said to be fatal to the ambition to explain our
knowledge or justification in general. But are the appeals relevantly
analogous? One important difference is this. In the example of the car, we
explain the presence, in some subject S, of a piece of knowledge of a certain
kind of the external world by appeal to the presence in S of some other piece
of knowledge of the very same kind. So there is an immediate problem if it is
our aim to explain how any knowledge of the sort in question ever comes to be
unless the explication is just beginning, and is to turn recursive in due
course. Now of course A is theoretically ambitious, and in that respect the
theorist who gives an answer of the form of A is doing something similar to
what must be done by the protagonist in our car example, someone who is
attempting to provide a general explanation of how any knowledge of a certain
kind comes about. Nevertheless, there is also an important difference, namely
that the theorist whose aim it is to give a general account of the form of A
need not attribute any knowledge whatsoever to a subject S in explaining how
that subject comes to have a piece of knowledge or justified belief. For there
is no need to require that the conditions C appealed to by principle A must be
conditions that include attribution of any knowledge at all to the subject in
question. It is true that in claiming that A itself meets conditions C, and
that it is this which explains how one knows A, we do perhaps take ourselves to
know A or at least to be justified in believing it. But if so, this is the
inevitable lot of anyone who seriously puts forward any explanation of
anything. And it is quite different from a proposal that part of what explains
how something is known or justifiably believed includes a claim to knowledge or
justified belief of the very same sort. In sum, as in the case of one’s belief
that one is awake, the belief in something of the form of A may be said to be
known, and in so saying one does not commit oneself to adducing an ulterior
reason in favor of A, or even to having such a reason in reserve. One is of
course committed to being justified in believing A, perhaps even to having
knowledge that A. But it is not at all clear that the only way to be justified
in believing A is by way of adduced reasons in favor of A, or that one knows A
only if one adduces strong enough reasons in its favor. For we often know
things in the absence of such adduced reasons. Thus consider one’s knowledge
through memory of which door one used to come into a room that has more than
one open door. Returning finally to A, in its case the explanation of how one
knows it may, once again, take the form of an appeal to the justifying power of
intellectual virtues or of coherence or
both. Recent accounts of the nature of thought and representation undermine a
tradition of wholesale doubt about nature, whose momentum is hard to stop, and
threatens to leave the subject alone and restricted to a solipsism of the
present moment. But there may be a way to stop skepticism early by questioning the possibility of its being
sensibly held, given what is required for meaningful language and thought.
Consider our grasp of observable shape and color properties that objects around
us might have. Such grasp seems partly constituted by our discriminatory
abilities. When we discern a shape or a color we do so presumably in terms of a
distinctive impact that such a shape or color has on us. We are put
systematically into a certain distinctive state X when we are appropriately
related, in good light, with our eyes open, etc., to the presence in our
environment of that shape or color. What makes one’s distinctive state one of
thinking of sphericity rather than something else, is said to be that it is a
state tied by systematic causal relations to skepticism skepticism 849 849 the presence of sphericity in one’s
normal environment. A light now flickers at the end of the skeptic’s tunnel. In
doubt now is the coherence of traditional skeptical reflection. Indeed, our
predecessors in earlier centuries may have moved in the wrong direction when
they attempted a reduction of nature to the mind. For there is no way to make
sense of one’s mind without its contents, and there is no way to make sense of
how one’s mind can have such contents except by appeal to how one is causally
related to one’s environment. If the very existence of that environment is put
in doubt, that cuts the ground from under one’s ability reasonably to
characterize one’s own mind, or to feel any confidence about its contents.
Perhaps, then, one could not be a “brain in a vat.” Much contemporary thought
about language and the requirements for meaningful language thus suggests that
a lot of knowledge must already be in place for us to be able to think
meaningfully about a surrounding reality, so as to be able to question its very
existence. If so, then radical skepticism answers itself. For if we can so much
as understand a radical skepticism about the existence of our surrounding
reality, then we must already know a great deal about that reality. Sceptics, those ancient thinkers who
developed sets of arguments to show either that no knowledge is possible
Academic Skepticism or that there is not sufficient or adequate evidence to
tell if any knowledge is possible. If the latter is the case then these
thinkers advocated suspending judgment on all question concerning knowledge
Pyrrhonian Skepticism. Academic Skepticism gets its name from the fact that it
was formulated in Plato’s Academy in the third century B.C., starting from
Socrates’ statement, “All I know is that I know nothing.” It was developed by
Arcesilaus c.268241 and Carneades c.213129, into a series of arguments,
directed principally against the Stoics, purporting to show that nothing can be
known. The Academics posed a series of problems to show that what we think we
know by our senses may be unreliable, and that we cannot be sure about the
reliability of our reasoning. We do not possess a guaranteed standard or
criterion for ascertaining which of our judgments is true or false. Any
purported knowledge claim contains some element that goes beyond immediate
experience. If this claim constituted knowledge we would have to know something
that could not possibly be false. The evidence for the claim would have to be
based on our senses and our reason, both of which are to some degree
unreliable. So the knowledge claim may be false or doubtful, and hence cannot
constitute genuine knowledge. So, the Academics said that nothing is certain.
The best we can attain is probable information. Carneades is supposed to have
developed a form of verification theory and a kind of probabilism, similar in
some ways to that of modern pragmatists and positivists. Academic Skepticism
dominated the philosophizing of Plato’s Academy until the first century B.C.
While Cicero was a student there, the Academy turned from Skepticism to a kind
of eclectic philosophy. Its Skeptical arguments have been preserved in Cicero’s
works, Academia and De natura deorum, in Augustine’s refutation in his Contra
academicos, as well as in the summary presented by Diogenes Laertius in his
lives of the Grecian philosophers. Skeptical thinking found another home in the
school of the Pyrrhonian Skeptics, probably connected with the Methodic school
of medicine in Alexandria. The Pyrrhonian movement traces its origins to Pyrrho
of Elis c.360275 B.C. and his student Timon c.315225 B.C.. The stories about
Pyrrho indicate that he was not a theoretician but a practical doubter who
would not make any judgments that went beyond immediate experience. He is
supposed to have refused to judge if what appeared to be chariots might strike
him, and he was often rescued by his students because he would not make any
commitments. His concerns were apparently ethical. He sought to avoid
unhappiness that might result from accepting any value theory. If the theory
was at all doubtful, accepting it might lead to mental anguish. The theoretical
formulation of Pyrrhonian Skepticism is attributed to Aenesidemus c.100 40
B.C.. Pyrrhonists regarded dogmatic philosophers and Academic Skeptics as
asserting too much, the former saying that something can be known and the
latter that nothing can be known. The Pyrrhonists suspended judgments on all
questions on which there was any conflicting evidence, including whether or not
anything could be known. The Pyrrhonists used some of the same kinds of
arguments developed by Arcesilaus and Carneades. Aenesidemus and those who
followed after him organized the arguments into sets of “tropes” or ways of
leading to suspense of judgment on various questions. Sets of ten, eight, five,
and two tropes appear in the only surviving writing of the Pyrrhonists, the
works of Sextus Empiricus, a third-century A.D. teacher of Pyrrhonism. Each set
of tropes offers suggestions for suspending judgment about any knowledge claims
that go beyond appearances. The tropes seek to show that for any claim,
evidence for and evidence against it can be offered. The disagreements among
human beings, the variety of human experiences, the fluctuation of human
judgments under differing conditions, illness, drunkenness, etc., all point to
the opposition of evidence for and against each knowledge claim. Any criterion
we employ to sift and weigh the evidence can also be opposed by
countercriterion claims. Given this situation, the Pyrrhonian Skeptics sought
to avoid committing themselves concerning any kind of question. They would not
even commit themselves as to whether the arguments they put forth were sound or
not. For them Skepticism was not a statable theory, but rather an ability or
mental attitude for opposing evidence for and against any knowledge claim that
went beyond what was apparent, that dealt with the non-evident. This opposing
produced an equipollence, a balancing of the opposing evidences, that would
lead to suspending judgment on any question. Suspending judgment led to a state
of mind called “ataraxia,” quietude, peace of mind, or unperturbedness. In such
a state the Skeptic was no longer concerned or worried or disturbed about
matters beyond appearances. The Pyrrhonians averred that Skepticism was a cure
for a disease called “dogmatism” or rashness. The dogmatists made assertions
about the non-evident, and then became disturbed about whether these assertions
were true. The disturbance became a mental disease or disorder. The
Pyrrhonians, who apparently were medical doctors, offered relief by showing the
patient how and why he should suspend judgment instead of dogmatizing. Then the
disease would disappear and the patient would be in a state of tranquillity,
the peace of mind sought by Hellenistic dogmatic philosophers. The Pyrrhonists,
unlike the Academic Skeptics, were not negative dogmatists. The Pyrrhonists
said neither that knowledge is possible nor that it is impossible. They
remained seekers, while allowing the Skeptical arguments and the equipollence
of evidences to act as a purge of dogmatic assertions. The purge eliminates all
dogmas as well as itself. After this the Pyrrhonist lives undogmatically,
following natural inclinations, immediate experience, and the laws and customs
of his society, without ever judging or committing himself to any view about
them. In this state the Pyrrhonist would have no worries, and yet be able to
function naturally and according to law and custom. The Pyrrhonian movement
disappeared during the third century A.D., possibly because it was not
considered an alternative to the powerful religious movements of the time. Only
scant traces of it appear before the Renaissance, when the texts of Sextus and
Cicero were rediscovered and used to formulate a modern skeptical view by such
thinkers as Montaigne and Charron. Refs.: The obvious source is the

Scheler, M.: G.
phenomenologist, social philosopher, and sociologist of knowledge. Born in
Munich, he studied in Jena; when he returned to Munich in 7 he came in contact
with phenomenology, especially the realist version of the early Husserl and his
Munich School followers. Scheler’s first works were phenomenological studies in
ethics leading to his ultimate theory of value: he described the moral feelings
of sympathy and resentment and wrote a criticism of Kantian formalism and
rationalism, Formalism in Ethics and a Non-Formal Ethics of Value 3. During the
war, he was an ardent nationalist and wrote essays in support of the war that
were also philosophical criticisms of modern culture, opposed to “Anglo-Saxon”
naturalism and rational calculation. Although he later embraced a broader
notion of community, such criticisms of modernity remained constant themes of
his writings. His conversion to Catholicism after the war led him to apply
phenomenological description to religious phenomena and feelings, and he later
turned to themes of anthropology and natural science. The core of Scheler’s
phenomenological method is his conception of the objectivity of essences,
which, though contained in experience, are a priori and independent of the
knower. For Scheler, values are such objective, though non-Platonic, essences.
Their objectivity is intuitively accessible in immediate experience and
feelings, as when we experience beauty in music and do not merely hear certain
sounds. Scheler distinguished between valuations or value perspectives on the
one hand, which are historically relative and variable, and values on the
other, which are independent and invariant. There are four such values, the
hierarchical organization of which could be both immediately intuited and
established by various public criteria like duration and independence:
pleasure, vitality, spirit, and religion. Corresponding to these values are
various personalities who are not creators of value but their discoverers,
historical disclosers, and exemplars: the “artist of consumption,” the hero,
the genius, and the saint. A similar hierarchy of values applies to forms of
society, the highest of which is the church, or a Christian community of
solidarity and love. Scheler criticizes the leveling tendencies of liberalism
for violating this hierarchy, leading to forms of resentment, individualism,
and nationalism, all of which represent the false ordering of values.
Schelling, Friedrich
Wilhelm Joseph, philosopher whose metamorscalar implicaturum Schelling,
Friedrich Wilhelm Joseph 816 816
phoses encompass the entire history of G. idealism. A Schwabian, Schelling
first studied at Tübingen, where he befriended Hölderlin and Hegel. The young
Schelling was an enthusiastic exponent of Fichte’s Wissenschaftslehre and
devoted several early essays to its exposition. After studying science and
mathematics at Leipzig, he joined Fichte at Jena in 1798. Meanwhile, in such
writings as Philosophische Briefe über Dogmatismus und Kritizismus
“Philosophical Letters on Dogmatism and Criticism,” 1795, Schelling betrayed
growing doubts concerning Fichte’s philosophy above all, its treatment of
nature and a lively interest in Spinoza. He then turned to constructing a
systematic Naturphilosophie philosophy of nature within the context of which
nature would be treated more holistically than by either Newtonian science or
transcendental idealism. Of his many publications on this topic, two of the
more important are Ideen zu einer Philosophie der Natur “Ideas concerning a
Philosophy of Nature,” 1797 and Von der Weltseele “On the World-Soul,” 1798.
Whereas transcendental idealism attempts to derive objective experience from an
initial act of free self-positing, Schelling’s philosophy of nature attempts to
derive consciousness from objects. Beginning with “pure objectivity,” the
Naturphilosophie purports to show how nature undergoes a process of unconscious
self-development, culminating in the conditions for its own
self-representation. The method of Naturphilosophie is fundamentally a priori:
it begins with the concept of the unity of nature and accounts for its
diversity by interpreting nature as a system of opposed forces or “polarities,”
which manifest themselves in ever more complex levels of organization Potenzen.
At Jena, Schelling came into contact with Tieck, Novalis, and the Schlegel
brothers and became interested in art. This new interest is evident in his
System des transzendentalen Idealismus 1800, which describes the path from pure
subjectivity self-consciousness to objectivity the necessary positing of the
Not-I, or of nature. The most innovative and influential portion of this
treatise, which is otherwise closely modeled on Fichte’s Wissenschaftslehre, is
its conclusion, which presents art as the concrete accomplishment of the
philosophical task. In aesthetic experience the identity between the subjective
and the objective, the ideal and the real, becomes an object to the experiencing
I itself. For Schelling, transcendental idealism and Naturphilosophie are two
complementary sides or subdivisions of a larger, more encompassing system,
which he dubbed the System of Identity or Absolute Idealism and expounded in a
series of publications, including the Darstellung meines Systems der
Philosophie “Presentation of My System of Philosophy,” 1801, Bruno 1802, and
Vorlesungen über die Methode des akademischen Studiums “Lectures on the Method
of Academic Study,” 1803. The most distinctive feature of this system is that
it begins with a bald assertion of the unity of thought and being, i.e., with
the bare idea of the self-identical “Absolute,” which is described as the first
presupposition of all knowledge. Since the identity with which this system
commences transcends every conceivable difference, it is also described as the
“point of indifference.” From this undifferentiated or “indifferent” starting
point, Schelling proceeds to a description of reality as a whole, considered as
a differentiated system within which unity is maintained by various synthetic
relationships, such as substance and attribute, cause and effect, attraction
and repulsion. Like his philosophy of nature, Schelling’s System of Identity
utilizes the notion of various hierarchically related Potenzen as its basic
organizing principle. The obvious question concerns the precise relationship
between the “indifferent” Absolute and the real system of differentiated
elements, a question that may be said to have set the agenda for Schelling’s
subsequent philosophizing. From 1803 to 1841 Schelling was in Bavaria, where he
continued to expound his System of Identity and to explore the philosophies of
art and nature. The most distinctive feature of his thought during this period,
however, was a new interest in religion and in the theosophical writings of
Boehme, whose influence is prominent in the Philosophische Untersuchungen über
das Wesen der menschlichen Freiheit “Philosophical Investigations concerning
the Nature of Human Freedom,” 1809, a work often interpreted as anticipating
existentialism. He also worked on a speculative interpretation of human
history, Die Weltalter, which remained unpublished, and lectured regularly on
the history of philosophy. In 1841 Schelling moved to Berlin, where he lectured
on his new philosophy of revelation and mythology, which he now characterized
as “positive philosophy,” in contradistinction to the purely “negative”
philosophy of Kant, Fichte, and Hegel. Some scholars have interpreted these posthumously
published lectures as representing the culmination both of Schelling’s own
protracted philosophical development and of G. idealism as a whole.
Schema (Latin ‘figura,’
as in Grice, ‘figure of speech’), also schema plural: schemata, a metalinguistic
frame or template used to specify an infinite set of sentences, its instances,
by finite means, often taken with a side condition on how its blanks or
placeholders are to be filled. The sentence ‘Either Abe argues or it is not the
case that Abe argues’ is an instance of the excluded middle scheme for English:
‘Either . . . or it is not the case that . . .’, where the two blanks are to be
filled with one and the same well-formed declarative English sentence. Since
first-order number theory cannot be finitely axiomatized, the mathematical
induction scheme is used to effectively specify an infinite set of axioms: ‘If
zero is such that . . . and the successor of every number such that . . . is
also such that . . . , then every number is such that . . .’, where the four
blanks are to be filled with one and the same arithmetic open sentence, such as
‘it precedes its own successor’ or ‘it is finite’. Among the best-known is
Tarski’s scheme T: ‘. . . is a true sentence if and only if . . .’, where the
second blank is filled with a sentence and the first blank by a name of the
sentence.
Schiller, Johann
Christoph Friedrich von, G. poet, dramatist, and philosopher. Along with his
colleagues Reinhold and Fichte, he participated in systematically revising
Kant’s transcendental idealism. Though Schiller’s bestknown theoretical
contributions were to aesthetics, his philosophical ambitions were more
general, and he proposed a novel solution to the problem of the systematic
unity, not merely of the critical philosophy, but of human nature. His most
substantial philosophical work, Briefe über die äesthetische Erziehung des
Menschen “Letters on the Aesthetic Education of Man,” 1794/95, examines the
relationship between natural necessity and practical freedom and addresses two
problems raised by Kant: How can a creature governed by natural necessity and
desire ever become aware of its own freedom and thus capable of autonomous
moral action? And how can these two sides of human nature the natural, sensuous side and the rational,
supersensuous one be reconciled? In
contradistinction both to those who subordinate principles to feelings
“savages” and to those who insist that one should strive to subordinate
feelings to principles “barbarians”, Schiller posited an intermediary realm
between the sphere of nature and that of freedom, as well as a third basic
human drive capable of mediating between sensuous and rational impulses. This
third impulse is dubbed the “play impulse,” and the intermediary sphere to
which it pertains is that of art and beauty. By cultivating the play impulse
i.e., via “aesthetic education” one is not only freed from bondage to
sensuality and granted a first glimpse of one’s practical freedom, but one also
becomes capable of reconciling the rational and sensuous sides of one’s own
nature. This idea of a condition in which opposites are simultaneously
cancelled and preserved, as well as the specific project of reconciling freedom
and necessity, profoundly influenced subsequent thinkers such as Schelling and
Hegel and contributed to the development of G. idealism.
Schlegel, Friedrich von,
G. literary critic and philosopher, one of the principal representatives of G.
Romanticism. In On the Study of Grecian Poetry 1795, Schlegel laid the
foundations for the distinction of classical and Romantic literature and a pronounced
consciousness of literary modernity. Together with his brother August Wilhelm,
he edited the Athenaeum 17981800, the main theoretical organ of G. Romanticism,
famous for its collection of fragments as a new means of critical
communication. Schlegel is the originator of the Romantic theory of irony, a
non-dialectical form of philosophizing and literary writing that takes its
inspiration from Socratic irony and combines it with Fichte’s thought process
of affirmation and negation, “self-creation” and “self-annihilation.” Closely
connected wih Schlegel’s theory of irony is his theory of language and
understanding hermeneutics. Critical reflection on language promotes an ironic
awareness of the “necessity and impossibility of complete communication” Critical
Fragments, No. 108; critical reflection on understanding reveals the amount of
incomprehensibility, of “positive not-understanding” involved in every act of
understanding On Incomprehensibility, 1800. Schlegel’s writings were essential
for the rise of historical consciousness in G. Romanticism. His On Ancient and
Modern Literature 1812 is reputed to represent the first literary history in a
modern and broadly comparative fashion. His Philosophy of History 1828,
together with his Philosophy of Life 1828 schema Schlegel, Friedrich von
818 818 and Philosophy of Language
1829, confront Hegel’s philosophy from the point of view of a Christian and
personalistic type of philosophizing. Schlegel converted to Catholicism in
1808.
Schleiermacher, F. G.
philosopher, a “critical realist” working among post-Kantian idealists. In
philosophy and science he presupposed transcendental features, noted in his
dialectic lectures, and advocated integrative but historically contingent,
empirical functions. Both develop, but, contra Hegel, not logically.
Schleiermacher was a creator of modern general hermeneutics; a father of modern
theological and religious studies; an advocate of women’s rights; the
cofounder, with Humboldt, of the at
Berlin 180810, where he taught until 1834; and the classic translator of Plato
into G.. Schleiermacher has had an undeservedly minor place in histories of
philosophy. Appointed chiefly to theology, he published less philosophy, though
he regularly lectured, in tightly argued discourse, in Grecian philosophy,
history of philosophy, dialectic, hermeneutics and criticism, philosophy of
mind “psychology”, ethics, politics, aesthetics, and philosophy of education.
From the 0s, his collected writings and large correspondence began to appear in
a forty-volume critical edition and in the larger Schleiermacher Studies and
Translations series. Brilliant, newly available pieces from his twenties on
freedom, the highest good, and values, previously known only in fragments but
essential for understanding his views fully, were among the first to appear.
Much of his outlook was formed before he became prominent in the early Romantic
circle 17961806, distinguishable by his markedly religious, consistently
liberal views.
Scholasticism, a set of
scholarly and instructional techniques developed in Western European schools of
the late medieval period, including the use of commentary and disputed
question. ‘Scholasticism’ is derived from Latin scholasticus, which in the
twelfth century meant the master of a school. The Scholastic method is usually
presented as beginning in the law schools
notably at Bologna and as being
then transported into theology and philosophy by a series of masters including
Abelard and Peter Lombard. Within the new universities of the thirteenth
century the standardization of the curriculum and the enormous prestige of
Aristotle’s work despite the suspicion with which it was initially greeted
contributed to the entrenchment of the method and it was not until the
educational reforms of the beginning of the sixteenth century that it ceased to
be dominant. There is, strictly speaking, no such thing as Scholasticism. As
the term was originally used it presupposed that a single philosophy was taught
in the universities of late medieval Europe, but there was no such philosophy.
The philosophical movements working outside the universities in the late
sixteenth and early seventeenth centuries and the “neo-Scholastics” of the late
nineteenth and early twentieth centuries all found such a presupposition
useful, and their influence led scholars to assume it. At first this generated
efforts to find a common core in the philosophies taught in the late medieval
schools. More recently it has led to efforts to find methods characteristic of
their teaching, and to an extension of the term to the schools of late
antiquity and of Byzantium. Both among the opponents of the schools in the
seventeenth century and among the “neoScholastics,” ‘Scholasticism’ was
supposed to designate a doctrine whose core was the doctrine of substance and
accidents. As portrayed by Descartes and Locke, the Scholastics accepted the
view that among the components of a thing were a substantial form and a number
of real accidental forms, many of which corresponded to perceptible properties
of the thing its color, shape,
temperature. They were also supposed to have accepted a sharp distinction
between natural and unnatural motion.
Schopenhauer, Arthur, G.
philosopher. Born in Danzig and schooled in G.y, France, and England during a
welltraveled childhood, he became acquainted through his novelist mother with
Goethe, Schlegel, and the brothers Grimm. He studied medicine at the of Göttingen and philosophy at the of Berlin; received the doctorate from
the of Jena in 1813; and lived much of
his adult life in Frankfurt, where he died. Schopenhauer’s dissertation, On the
Fourfold Root of the Principle of Sufficient Reason 1813, lays the groundwork
for all of his later philosophical work. The world of representation equivalent
to Kant’s phenomenal world is governed by “the principle of sufficient reason”:
“every possible object . . . stands in a necessary relation to other objects,
on the one hand as determined, on the other as determining” The World as Will
and Representation. Thus, each object of consciousness can be explained in
terms of its relations with other objects. The systematic statement of
Schopenhauer’s philosophy appeared in The World as Will and Representation
1818. His other works are On Vision and Colors 1815, “On the Will in Nature”
1836, conjoined with “On the Foundation of Morality” in The Two Fundamental
Problems of Ethics 1841; the second edition of The World as Will and
Representation, which included a second volume of essays 1844; an enlarged and
revised edition of On the Fourfold Root of the Principle of Sufficient Reason
1847; and Parerga and Paralipomena, a series of essays 1851. These are all
consistent with the principal statement of his thought in The World as Will and
Representation. The central postulate of Schopenhauer’s system is that the
fundamental reality is will, which he equates with the Kantian thing-in-itself.
Unlike Kant, Schopenhauer contends that one can immediately know the
thing-in-itself through the experience of an inner, volitional reality within
one’s own body. Every phenomenon, according to Schopenhauer, has a comparable
inner reality. Consequently, the term ‘will’ can extend to the inner nature of
all things. Moreover, because number pertains exclusively to the phenomenal
world, the will, as thing-initself, is one. Nevertheless, different types of
things manifest the will to different degrees. Schopenhauer accounts for these
differences by invoking Plato’s Ideas or Forms. The Ideas are the universal
prototypes for the various kinds of objects in the phenomenal world. Taken
collectively, the Ideas constitute a hierarchy. We usually overlook them in
everyday experience, focusing instead on particulars and their practical
relationships to us. However, during aesthetic experience, we recognize the
universal Idea within the particular; simultaneously, as aesthetic beholders,
we become “the universal subject of knowledge.” Aesthetic experience also
quiets the will within us. The complete silencing of the will is, for
Schopenhauer, the ideal for human beings, though it is rarely attained. Because
will is the fundamental metaphysical principle, our lives are dominated by
willing and, consequently, filled with
struggle, conflict, and dissatisfaction. Inspired by Buddhism, Schopenhauer
contends that all of life is suffering, which only an end to desire can
permanently eliminate as opposed to the respite of aesthetic experience. This
is achieved only by the saint, who rejects desire in an inner act termed
“denial of the will to live.” The saint fully grasps that the same will
motivates all phenomena and, recognizing that nothing is gained through
struggle and competition, achieves “resignation.” Such a person achieves the
ethical ideal of all religions
compassion toward all beings, resulting from the insight that all are,
fundamentally, one.
Schröder-Bernstein
theorem, the theorem that mutually dominant sets are equinumerous. A set A is
said to be dominated by a set B if and only if each element of A can be mapped
to a unique element of B in such a way that no two elements of A are mapped to
the same element of B possibly with some elements of B left over. Intuitively,
if A is dominated by B, then B has at least as many members as A. Given this
intuition, one would expect that if A is dominated by B and B is dominated by
A, then A and B are equinumerous i.e., A can be mapped to B as described above
with no elements of B left over. This is the Schröder-Bernstein theorem. Stated
in terms of cardinal numbers, the theorem says that if k m l and l m k, then k
% l. Despite the simplicity of the theorem’s statement, its proof is
non-trivial.
Schrödinger, Erwin, Austrian
physicist best known for five papers published in 6, in which he discovered the
Schrödinger wave equation and created modern wave mechanics. For this
achievement, he was awarded the Nobel prize in physics shared with Paul Dirac
in 3. Like Einstein, Schrödinger was a resolute but ultimately unsuccessful
critic of the Copenhagen interpretation of quantum mechanics. Schrödinger
defended the view which he derived from Boltzmann that theories should give a
picture, continuous in space and time, of the real processes that produce
observable phenomena. Schrödinger’s realistic philosophy of science played an
important role in his discovery of wave mechanics. Although his physical
interpretation of the psi function was soon abandoned, his approach to quantum
mechanics survives in the theories of Louis de Broglie and David Bohm.
.Schulze, Gottlob Ernst,
G. philosopher today known mainly as an acute and influential early critic of
Kant and Reinhold. He taught at Wittenberg, Helmstedt, and Göttingen; one of
his most important students was Schopenhauer, whose view of Kant was definitely
influenced by Schulze’s interpretation. Schulze’s most important work was his
Aenesidemus, or “On the Elementary Philosophy Put Forward by Mr. Reinhold in
Jena. Together with a Defense of Skepticism” 1792. It fundamentally changed the
discussion of Kantian philosophy. Kant’s earliest critics had accused him of
being a skeptic like Hume. Kantians, like Reinhold, had argued that critical
philosophy was not only opposed to skepticism, but also contained the only
possible refutation of skepticism. Schulze tried to show that Kantianism could
not refute skepticism, construed as the doctrine that doubts the possibility of
any knowledge concerning the existence or non-existence of
“things-in-themselves,” and he argued that Kant and his followers begged the
skeptic’s question by presupposing that such things exist and causally interact
with us. Schulze’s Aenesidemus had a great impact on Fichte and Hegel, and it
also influenced neoKantianism.
realism, the view that
the subject matter of common sense or scientific research and scientific
theories exists independently of our knowledge of it, and that the goal of
science is the description and explanation of both observable and unobservable
aspects of the world. Scientific realism is contrasted with logical empiricism
and social constructivism. Early arguments for scientific realism simply stated
that, in light of the impressive products and methods of science, realism is
the only philosophy that does not make the success of science a miracle.
Formulations of scientific realism focus on the objects of theoretical
knowledge: theories, laws, and entities. One especially robust argument for
scientific realism due to Putnam and Richard Boyd is that the instrumental
reliability of scientific methodology in the mature sciences such as physics,
chemistry, and some areas of biology can be explained adequately only if we
suppose that theories in the mature sciences are at least approximately true
and their central theoretical terms are at least partially referential Putnam
no longer holds this view. More timid versions of scientific realism do not
infer approximate truth of mature theories. For example, Ian Hacking’s “entity
realism” 3 asserts that the instrumental manipulation of postulated entities to
produce further effects gives us legitimate grounds for ontological commitment
to theoretical entities, but not to laws or theories. Paul Humphreys’s “austere
realism” 9 states that only theoretical commitment to unobserved structures or
dispositions could explain the stability of observed outcomes of scientific
inquiry. Distinctive versions of scientific realism can be found in works by
Richard Boyd 3, Philip Kitcher 3, Richard Miller 7, William Newton-Smith 1, and
J. D. Trout 8. Despite their differences, all of these versions of realism are
distinguished against logical
empiricism by their commitment that
knowledge of unobservable phenomena is not only possible but actual. As well,
all of the arguments for scientific realism are abductive; they argue that
either the approximate truth of background theories or the existence of
theoretical entities and laws provides the best explanation for some
significant fact about the scientific theory or practice. Scientific realists
address the difference between real entities and merely useful constructs,
arguing that realism offers a better explanation for the success of science. In
addition, scientific realism recruits evidence from the history and practice of
science, and offers explanations for the success of science that are designed
to honor the dynamic and uneven character of that evidence. Most arguments for
scientific realism cohabit with versions of naturalism. Anti-realist opponents
argue that the realist move from instrumental reliability to truth is
question-begging. However, realists reply that such formal criticisms are
irrelevant; the structure of explanationist arguments is inductive and their
principles are a posteriori.
scope, the “part” of the
sentence or proposition to which a given term “applies” under a given
interpretation of the sentence. If the sentence ‘Abe does not believe Ben died’
is interpreted as expressing the proposition that Abe believes that it is not
the case that Ben died, the scope of ‘not’ is ‘Ben died’; interpreted as “It is
not the case that Abe believes that Ben died,” the scope is the rest of the
sentence, i.e., ‘Abe believes Ben died’. In the first case we have narrow
scope, in the second wide scope. If ‘Every number is not even’ is interpreted
with narrow scope, it expresses the false proposition that every number is
non-even, which is logically equivalent to the proposition that no number is
even. Taken with wide scope it expresses the truth that not every number is
even, which is equivalent to the truth that some number is non-even. Under
normal interpretations of the sentences, ‘hardened’ has narrow scope in ‘Carl
is a hardened recidivist’, whereas ‘alleged’ has wide scope in ‘Dan is an
alleged criminal’. Accordingly, ‘Carl is a hardened recidivist’ logically
implies ‘Carl is a recidivist’, whereas ‘Dan is an alleged criminal’, being
equivalent to ‘Allegedly, Dan is a criminal’, does not imply ‘Dan is a
criminal’. Scope considerations are useful in analyzing structural ambiguity
and in understanding the difference between the grammatical form of a sentence
and the logical form of a proposition it expresses. In a logically perfect
language grammatical form mirrors logical form, there is no scope ambiguity,
and the scope of a given term is uniquely determined by its context.
Scottish common sense
philosophy, a comprehensive philosophical position developed by Reid in the
latter part of the eighteenth century. Reid’s views were propagated by a
succession of Scottish popularizers, of whom the most successful was Dugald
Stewart. Through them common sense doctrine became nearly a philosophical
orthodoxy in Great Britain during the first half of the nineteenth century.
Brought to the United States through the s in Princeton and Philadelphia,
common sensism continued to be widely taught until the later nineteenth
century. The early Reidians Beattie and Oswald were, like Reid himself, read in
G.y by Kant and others; and Reid’s views were widely taught in post-Napoleonic
France. The archenemy for the common sense theorists was Hume. Reid saw in his
skepticism the inevitable outcome of Descartes’s thesis, accepted by Locke,
that we do not perceive external objects directly, but that the immediate
object of perception is something in the mind. Against this he argued that
perception involves both sensation and certain intuitively known general truths
or principles that together yield knowledge of external objects. He also argued
that there are many other intuitively known general principles, including moral
principles, available to all normal humans. As a result he thought that
whenever philosophical argument results in conclusions that run counter to
common sense, the philosophy must be wrong. Stewart made some changes in Reid’s
acute and original theory, but his main achievement was to propagate it through
eloquent classes and widely used textbooks. Common sensism, defending the
considered views of the ordinary man, was taken by many to provide a defense of
the Christian religious and moral status quo. Reid had argued for free will,
and presented a long list of self-evident moral axioms. If this might be
plausibly presented as part of the common sense of his time, the same could not
be said for some of the religious doctrines that Oswald thought equally
self-evident. Reid had not given any rigorous tests for what might count as
selfevident. The easy intuitionism of later common sensists was a natural
target for those who, like J. S. Mill, thought that any appeal to self-evidence
was simply a way of justifying vested interest. Whewell, in both his philosophy
of science and his ethics, and Sidgwick, in his moral theory, acknowledged
debts to Reid and tried to eliminate the abuses to which his method was open.
But in doing so they transformed common sensism beyond the limits within which
Reid and those shaped by him operated.
Searle, John R. b.2, philosopher of language and mind D. Phil.,
Oxford influenced by Frege, Vitters, and J. L. Austin; a founder of speech act
theory and an important contributor to debates on intentionality,
consciousness, and institutional facts. Language. In Speech Acts: An Essay in
the Philosophy of Language 9, Searle brings together modified versions of
Frege’s distinctions between the force F and content P of a sentence, and
between singular reference and predication, Austin’s analysis of speech acts,
and Grice’s analysis of speaker meaning. Searle explores the hypothesis that
the semantics of a natural language can be regarded as a conventional
realization of underlying constitutive rules and that illocutionary acts are
acts performed in accordance with these rules. Expression and Meaning 9 extends
this analysis to non-literal and indirect illocutionary acts, and attempts to
explain Donnellan’s referential-attributive distinction in these terms and
proposes an influential taxonomy of five basic types of illocutionary acts
based on the illocutionary point or purpose of the act, and word-to-world
versus world-toword direction of fit. Language and mind. Intentionality: An
Essay in the Philosophy of Mind 3 forms the foundation for the earlier work on
speech acts. Now the semantics of a natural language is seen as the result of
the mind intrinsic intentionality imposing conditions of satisfaction or
aboutness on objects expressions in a language, which have intentionality only
derivatively. Perception and action rather than belief are taken as
fundamental. Satisfaction conditions are essentially Fregean i.e. general
versus singular and internal meaning is
in the head, relative to a background of non-intentional states, and relative
to a network of other intentional states. The philosophy of language becomes a
branch of the philosophy of mind. Mind. “Minds, Brains and Programs” 0
introduced the famous “Chin. room” argument against strong artificial
intelligence the view that appropriately
programming a machine is sufficient for giving it intentional states. Suppose a
monolingual English-speaker is working in a room producing Chin. answers to
Chin. questions well enough to mimic a Chin.speaker, but by following an
algorithm written in English. Such a person does not understand Chin. nor would
a computer computing the same algorithm. This is true for any such algorithms
because they are syntactically individuated and intentional states are
semantically individuated. The Rediscovery of the Mind 2 continues the attack
on the thesis that the brain is a digital computer, and develops a non-reductive
“biological naturalism” on which intentionality, like the liquidity of water,
is a high-level feature, which is caused by and realized in the brain. Society.
The Construction of Social Reality 5 develops his realistic worldview, starting
with an independent world of particles and forces, up through evolutionary
biological systems capable of consciousness and intentionality, to institutions
and social facts, which are created when persons impose status-features on
things, which are collectively recognized and accepted.
First-order predicate
calculus with time-relative identity -- second-order logic, the logic of
languages that contain, in addition to variables ranging over objects,
variables ranging over properties, relations, functions, or classes of those
objects. A model, or interpretation, of a formal language usually contains a
domain of discourse. This domain is what the language is about, in the model in
question. Variables that range over this domain are called first-order
variables. If the language contains only first-order variables, it is called a
first-order language, and it is within the purview of first-order logic. Some
languages also contain variables that range over properties, relations,
functions, or classes of members of the domain of discourse. These are
second-order variables. A language that contains first-order and second-order
variables, and no others, is a secondorder language. The sentence ‘There is a
property shared by all and only prime numbers’ is straightforwardly rendered in
a second-order language, because of the bound variable ranging over properties.
There are also properties of properties, relations of properties, and the like.
Consider, e.g., the property of properties expressed by ‘P has an infinite
extension’ or the relation expressed by ‘P has a smaller extension than Q’. A
language with variables ranging over such items is called thirdorder. This
construction can be continued, producing fourth-order languages, etc. A
language is called higher-order if it is at least second-order. Deductive
systems for second-order languages are obtained from those for first-order
languages by adding straightforward extensions of the axioms and rules
concerning quantifiers that bind first-order variables. There may also be an axiom
scheme of comprehension: DPExPx S Fx, one instance for each formula F that does
not contain P free. The scheme “asserts” that every formula determines the
extension of a property. If the language has variables ranging over functions,
there may also be a version of the axiom of choice: ERExDyRxy P DfExRxfx. In
standard semantics for second-order logic, a model of a given language is the
same as a model for the corresponding first-order language. The relation
variables range over every relation over the domain-of-discourse, the function
variables range over every function from the domain to the domain, etc. In
non-standard, or Henkin semantics, each model consists of a domain-ofdiscourse
and a specified collection of relations, functions, etc., on the domain. The
latter may not include every relation or function. The specified collections
are the range of the second-order variables in the model in question. In
effect, Henkin semantics regards second-order languages as multi-sorted,
first-order languages.
secundum quid, in a
certain respect, or with a qualification. Fallacies can arise from confusing
what is true only secundum quid with what is true simpliciter ‘without
qualification’, ‘absolutely’, ‘on the whole’, or conversely. Thus a strawberry
is red simpliciter on the whole. But it is black, not red, with respect to its
seeds, secundum quid. By ignoring the distinction, one might mistakenly infer
that the strawberry is both red and not red. Again, a certain thief is a good
cook, secundum quid; but it does not follow that he is good simpliciter without
qualification. Aristotle was the first to recognize the fallacy secundum quid
et simpliciter explicitly, in his Sophistical Refutations. On the basis of some
exceptionally enigmatic remarks in the same work, the liar paradox was often
regarded in the Middle Ages as an instance of this fallacy.
Auto-deception – D. F.
Pears -- self-deception, 1 purposeful action to avoid unpleasant truths and
painful topics about oneself or the world; 2 unintentional processes of denial,
avoidance, or biased perception; 3 mental states resulting from such action or
processes, such as ignorance, false belief, wishful thinking, unjustified
opinions, or lack of clear awareness. Thus, parents tend to exaggerate the
virtues of their children; lovers disregard clear signs of unreciprocated
affection; overeaters rationalize away the need to diet; patients dying of
cancer pretend to themselves that their health is improving. In some contexts
‘self-deception’ is neutral and implies no criticism. Deceiving oneself can
even be desirable, generating a vital lie that promotes happiness or the
ability to cope with difficulties. In other contexts ‘self-deception’ has
negative connotations, suggesting bad faith, false consciousness, or what Joseph
Butler called “inner hypocrisy” the
refusal to acknowledge our wrongdoing, character flaws, or onerous
responsibilities. Existentialist philosophers, like Kierkegaard, Heidegger, and
most notably Sartre Being and Nothingness, 3, denounced self-deception as an
inauthentic dishonest, cowardly refusal to confront painful though significant
truths, especially about freedom, responsibility, and death. Herbert
Fingarette, however, argued that self-deception is morally ambiguous neither clearly blameworthy nor clearly
faultless because of how it erodes
capacities for acting rationally Self-Deception, 9. The idea of intentionally
deceiving oneself seems paradoxical. In deceiving other people I usually know a
truth that guides me as I state the opposite falsehood, intending thereby to
mislead them into believing the falsehood. Five difficulties seem to prevent me
from doing anything like that to myself. 1 With interpersonal deception, one
person knows something that another person does not. Yet self-deceivers know
the truth all along, and so it seems they cannot use it to make themselves
ignorant. One solution is that self-deception occurs over time, with the
initial knowledge becoming gradually eroded. Or perhaps selfdeceivers only
suspect rather than know the truth, and then disregard relevant evidence. 2 If
consciousness implies awareness of one’s own conscious acts, then a conscious
intention to deceive myself would be self-defeating, for I would remain
conscious of the truth I wish to flee. Sartre’s solution was to view
self-deception as spontaneous and not explicitly reflected upon. Freud’s
solution was to conceive of self-deception as unconscious repression. 3 It
seems that self-deceivers believe a truth that they simultaneously get
themselves not to believe, but how is that possible? Perhaps they keep one of
two conflicting beliefs unconscious or not fully conscious. 4 Self-deception
suggests willfully creating beliefs, but that seems impossible since beliefs
cannot voluntarily be chosen. Perhaps beliefs can be indirectly manipulated by
selectively ignoring and attending to evidence. 5 It seems that one part of a
person the deceiver manipulates another part the victim, but such extreme
splits suggest multiple personality disorders rather than self-deception.
Perhaps we are composed of “subselves”
relatively unified clusters of elements in the personality. Or perhaps
at this point we should jettison interpersonal deception as a model for
understanding self-deception. .
auto-determination -- self-determination,
the autonomy possessed by a community when it is politically independent; in a
strict sense, territorial sovereignty. Within international law, the principle
of self-determination appears to grant every people a right to be
self-determining, but there is controversy over its interpretation. Applied to
established states, the principle calls for recognition of state sovereignty
and non-intervention in internal affairs. By providing for the
self-determination of subordinate communities, however, it can generate demands
for secession that conflict with existing claims of sovereignty. Also, what
non-self-governing groups qualify as beneficiaries? The national interpretation
of the principle treats cultural or national units as the proper claimants,
whereas the regional interpretation confers the right of self-determination
upon the populations of well-defined regions regardless of cultural or national
affiliations. This difference reflects the roots of the principle in the
doctrines of nationalism and popular sovereignty, respectively, but complicates
its application.
self-evidence, the
property of being self-evident. Only true propositions or truths are
self-evident, though false propositions can appear to be self-evident. It is
widely held that a true proposition is self-evident if and only if one would be
justified in believing it if one adequately understood it. Some would also
require that self-evident propositions are known if believed on the basis of
such an understanding. Some self-evident propositions are obvious, such as the
proposition that all stags are male, but others are not, since it may take
considerable reflection to achieve an adequate understanding of them. That
slavery is wrong and that there is no knowledge of falsehoods are perhaps examples
of the latter. Not all obvious propositions are self-evident, e.g., it is
obvious that a stone will fall if dropped, but adequate understanding of that
claim does not by itself justify one in believing it. An obvious proposition is
one that immediately seems true for anyone who adequately understands it, but
its obviousness may rest on wellknown and commonly accepted empirical facts,
not on understanding. All analytic propositions are self-evident but not all
self-evident propositions are analytic. The propositions that if A is older
than B, then B is younger than A, and that no object can be red and green all
over at the same time and in the same respects, are arguably self-evident but
not analytic. All self-evident propositions are necessary, for one could not be
justified in believing a contingent proposition simply in virtue of
understanding it. However, not all necessary propositions are self-evident,
e.g., that water is H2O and that temperature is the measure of the molecular
activity in substances are necessary but not self-evident. A proposition can
appear to be selfevident even though it is not. For instance, the proposition
that all unmarried adult males are bachelors will appear self-evident to many
until they consider that the pope is such a male. A proposition may appear
self-evident to some but not to others, even though it must either have or lack
the property of being self-evident. Self-evident propositions are knowable
non-empirically, or a priori, but some propositions knowable a priori are not
self-evident, e.g., certain conclusions of long and difficult chains of
mathematical reasoning.
self-presenting, in the
philosophy of Meinong, having the ability
common to all mental states to be
immediately present to our thought. In Meinong’s view, no mental state can be
presented to our thought in any other way
e.g., indirectly, via a Lockean “idea of reflection.” The only way to
apprehend a mental state is to experience or “live through” it. The experience
involved in the apprehension of an external object has thus a double
presentational function: 1 via its “content” it presents the object to our
thought; 2 as its own “quasi-content” it presents itself immediately to our
thought. In the contemporary era, Roderick Chisholm has based his account of
empirical knowledge in part on a related concept of the self-presenting. In
Chisholm’s sense the definition of which
we omit here all self-presenting states
are mental, but not conversely; for instance, being depressed because of the
death of one’s spouse would not be self-presenting. In Chisholm’s epistemology,
self-presenting states are a source of certainty in the following way: if F is
a self-presenting state, then to be certain that one is in state F it is
sufficient that one is, and believes oneself to be in state F.
auto-phoric -- self-referential
incoherence, an internal defect of an assertion or theory, which it possesses
provided that a it establishes some requirement that must be met by assertions
or theories, b it is itself subject to this requirement, and c it fails to meet
the requirement. The most famous example is logical positivism’s meaning
criterion, which requires that all meaningful assertions be either tautological
or empirically verifiable, yet is itself neither. A possible early example is
found in Hume, whose own writings might have been consigned to the flames had
librarians followed his counsel to do so with volumes that contain neither
“abstract reasoning concerning quantity or number” nor “experimental reasoning
concerning matter of fact and existence.” Bold defiance was shown by Vitters,
who, realizing that the propositions of the Tractatus did not “picture” the
world, advised the reader to “throw away the ladder after he has climbed up
it.” An epistemological example is furnished by any foundationalist theory that
establishes criteria for rational acceptability that the theory itself cannot
meet.
self-reproducing
automaton, a formal model of self-reproduction of a kind introduced by von
Neumann. He worked with an intuitive robot model and then with a well-defined
cellular automaton model. Imagine a class of robotic automata made of robot
parts and operating in an environment of such parts. There are computer parts
switches, memory elements, wires, input-output parts sensing elements, display
elements, action parts grasping and moving elements, joining and cutting
elements, and straight bars to maintain structure and to employ in a storage
tape. There are also energy sources that enable the robots to operate and move
around. These five categories of parts are sufficient for the construction of
robots that can make objects of various kinds, including other robots. These
parts also clearly suffice for making a robot version of any finite automaton.
Sensing and acting parts can then be added to this robot so that it can make an
indefinitely expandable storage tape from straight bars. A “blank tape”
consists of bars joined in sequence, and the robot stores information on this
tape by attaching bars or not at the junctions. If its finite automaton part
can execute programs and is sufficiently powerful, such a robot is a universal
computing robot cf. a universal Turing machine. A universal computing robot can
be augmented to form a universal constructing robot a robot that can construct any robot, given
its description. Let r be any robot with an indefinitely expandable tape, let
Fr be the description of its finite part, and let Tr be the information on its
tape. Now take a universal computing robot and augment it with sensing and
acting devices and with programs so that when Fr followed by Tr is written on
its tape, this augmented universal computer performs as follows. First, it
reads the description Fr, finds the needed parts, and constructs the finite
part of r. Second, it makes a blank tape, attaches it to the finite part of r,
and then copies the information Tr from its own tape onto the new tape. This
augmentation of a universal computing robot is a universal constructor. For
when it starts with the information Fr,Tr written on its tape, it will
construct a copy of r with Tr on its tape. Robot self-reproduction results from
applying the universal constructor to itself. Modify the universal constructor
slightly so that when only a description Fr is written on its tape, it constructs
the finite part of r and then attaches a tape with Fr written on it. Call this
version of the universal constructor Cu. Now place Cu’s description FCu on its
own tape and start it up. Cu first reads this description and constructs a copy
of the finite part of itself in an empty region of the cellular space. Then it
adds a blank tape to the new construction and copies FCu onto it. Hence Cu with
FCu on its tape has produced another copy of Cu with FCu on its tape. This is
automaton self-reproduction. This robot model of self-reproduction is very
general. To develop the logic of self-reproduction further, von Neumann first
extended the concept of a finite automaton to that of an infinite cellular
automaton consisting of an array or “space” of cells, each cell containing the
same finite automaton. He chose an infinite checkerboard array for modeling
self-reproduction, and he specified a particular twenty-nine-state automaton
for each square cell. Each automaton is connected directly to its four
contiguous neighbors, and communication between neighbors takes one or two
time-steps. The twenty-nine states of a cell fall into three categories. There
is a blank state to represent the passivity of an empty area. There are twelve
states for switching, storage, and communication, from which any finite
automaton can be constructed in a sufficiently large region of cells. And there
are sixteen states for simulating the activities of construction and
destruction. Von Neumann chose these twenty-nine states in such a way that an
area of non-blank cells could compute and grow, i.e., activate a path of cells
out to a blank region and convert the cells of that region into a cellular
automaton. A specific cellular automaton is embedded in this space by the
selection of the initial states of a finite area of cells, all other cells
being left blank. A universal computer consists of a sufficiently powerful
finite automaton with a tape. The tape is an indefinitely long row of cells in
which bits are represented by two different cell states. The finite automaton
accesses these cells by means of a construction arm that it extends back and
forth in rows of cells contiguous to the tape. When activated, this finite
automaton will execute programs stored on its tape. A universal constructor
results from augmenting the universal computer cf. the robot model. Another
construction arm is added, together with a finite automaton controller to
operate it. The controller sends signals into the arm to extend it out to a
blank region of the cellular space, to move around that region, and to change
the states of cells in that region. After the universal constructor has
converted the region into a cellular automaton, it directs the construction arm
to activate the new automaton and then withdraw from it. Cellular automaton
selfreproduction results from applying the universal constructor to itself, as
in the robot model. Cellular automata are now studied extensively by humans
working interactively with computers as abstract models of both physical and organic
systems. See Arthur W. Burks, “Von Neumann’s Self-Reproducing Automata,” in
Papers of John von Neumann on Computers and Computer Theory, edited by William
Aspray and Arthur Burks, 7. The study of artificial life is an outgrowth of
computer simulations of cellular automata and related automata. Cellular
automata organizations are sometimes used in highly parallel computers.
Sellars, W., philosopher,
son of Roy Wood Sellars, and one of the great systematic philosophers of the
century. His most influential and representative works are “Empiricism and the
Philosophy of Mind” 6 and “Philosophy and the Scientific Image of Man” 0. The
Sellarsian system may be outlined as follows. The myth of the given. Thesis 1:
Classical empiricism foundationalism maintains that our belief in the
commonsense, objective world of physical objects is ultimately justified only
by the way that world presents itself in sense experience. Thesis 2: It also
typically maintains that sense experience a is not part of that world and b is
not a form of conceptual cognition like thinking or believing. Thesis 3: From 1
and 2a classical empiricism concludes that our knowledge of the physical world
is inferred from sense experience. Thesis 4: Since inferences derive knowledge
from knowledge, sense experience itself must be a form of knowledge. Theses 14
collectively are the doctrine of the given. Each thesis taken individually is
plausible. However, Sellars argues that 2b and 4 are incompatible if, as he
thinks, knowledge is a kind of conceptual cognition. Concluding that the
doctrine of the given is false, he maintains that classical empiricism is a
myth. The positive system. From an analysis of theoretical explanation in the
physical sciences, Sellars concludes that postulating theoretical entities is
justified only if theoretical laws
nomological generalizations referring to theoretical entities are needed to explain particular observable
phenomena for which explanation in terms of exceptionless observation laws is
unavailable. While rejecting any classical empiricist interpretation of
observation, Sellars agrees that some account of non-inferential knowledge is
required to make sense of theoretical explanation thus conceived. He thinks
that utterances made in direct response to sensory stimuli observational
reports count as non-inferential knowledge when a they possess authority, i.e.,
occur in conditions ensuring that they reliably indicate some physical property
say, shape in the environment and are accepted by the linguistic community as
possessing this quality; and b the utterer has justified belief that they
possess this authority. Sellars claims that some perceptual conditions induce
ordinary people to make observation reports inconsistent with established
explanatory principles of the commonsense framework. We thus might tend to
report spontaneously that an object is green seen in daylight and blue seen
indoors, and yet think it has not undergone any process that could change its
color. Sellars sees in such conflicting tendencies vestiges of a primitive
conceptual framework whose tensions have been partially resolved by introducing
the concept of sense experiences. These experiences count as theoretical
entities, since they are postulated to account for observational phenomena for
which no exceptionless observation laws exist. This example may serve as a
paradigm for a process of theoretical explanation occurring in the framework of
commonsense beliefs that Sellars calls the manifest image, a process that
itself is a model for his theory of the rational dynamics of conceptual change
in both the manifest image and in science
the scientific image. Because the actual process of conceptual evolution
in Homo sapiens may not fit this pattern of rational dynamics, Sellars treats
these dynamics as occurring within certain hypothetical ideal histories myths
of the way in which, from certain conceptually primitive beginnings, one might
have come to postulate the requisite theoretical explanations. The manifest
image, like the proto-theories from which it arose, is itself subject to
various tensions ultimately resolved in the scientific image. Because this
latter image contains a metaphysical theory of material objects and persons
that is inconsistent with that of its predecessor framework, Sellars regards
the manifest image as replaced by its successor. In terms of the Peircean
conception of truth that Sellars endorses, the scientific image is the only
true image. In this sense Sellars is a scientific realist. There is, however,
also an important sense in which Sellars is not a scientific realist: despite
discrediting classical empiricism, he thinks that the intrinsic nature of sense
experience gives to conceptualization more than simply sensory stimulus yet
less than the content of knowledge claims. Inspired by Kant, Sellars treats the
manifest image as a Kantian phenomenal world, a world that exists as a
cognitive construction which, though lacking ideal factual truth, is guided in
part by intrinsic features of sense experience. This is not analytic
phenomenalism, which Sellars rejects. Moreover, the special methodological role
for sense experience has effects even within the scientific image itself.
Theories of mind, perception, and semantics. Mind: In the manifest image
thoughts are private episodes endowed with intentionality. Called inner speech,
they are theoretical entities whose causal and intentional properties are
modeled, respectively, on inferential and semantic properties of overt speech.
They are introduced within a behaviorist proto-theory, the Rylean framework, to
provide a theoretical explanation for behavior normally accompanied by
linguistically overt reasons. Perception: In the manifest image sense
experiences are sense impressions states
of persons modeled on two-dimensional, colored physical replicas and introduced
in the theoretical language of the adverbial theory of perception to explain
why it can look as if some perceptible quality is present when it is not.
Semantics: The meaning of a simple predicate p in a language L is the role
played in L by p defined in terms of three sets of linguistic rules: language
entry rules, intralinguistic rules, and language departure rules. This account
also supports a nominalist treatment of abstract entities. Identification of a
role for a token of p in L can be effected demonstratively in the speaker’s
language by saying that p in L is a member of the class of predicates playing
the same role as a demonstrated predicate. Thus a speaker of English might say
that ‘rot’ in G. plays the semantic role ‘red’ has in English. Sellars sees
science and metaphysics as autonomous strands in a single web of philosophical
inquiry. Sellarsianism thus presents an important alternative to the view that
what is fundamentally real is determined by the logical structure of scientific
language alone. Sellars also sees ordinary language as expressing a commonsense
framework of beliefs constituting a kind of proto-theory with its own methods,
metaphysics, and theoretical entities. Thus, he also presents an important alternative
to the view that philosophy concerns not what is ultimately real, but what
words like ‘real’ ultimately mean in ordinary language.
semantics:
Grice was careful with what he felt was an abuse of ‘semantic’ – v. Evans:
“Meaning and truth: essayis in semantics.” “Well, that’s what ‘meaning’ means,
right?” The semantics is more reated to the signatum than to the significatum.
The Grecians did not have anything remotely similar to the significatum, which
is all about the making (facere) of a sign (as in Grice’s example of the
handwave). This is the meaning Grice gives to ‘semantics.’ There is no need for
the handwave to be part of a system of communication, or have syntactic
structure, or be ‘arbitrary.’ Still, one thing is communicated from the emissor
to his recipient, and that is all count. “I know the route” is the message, or
“I will leave you soon.” The handwave may be ambiguous. Grice is aware that
formalists like Hilbert and Gentzen think that they can do without semantics –
but as long as there is something ‘transmitted,’ or ‘messaged,’ it cannot. In
the one-off predicament, Emissor E emits x and communicates that p. Since an
intention with a content involving a psychological state is involved and
attached, even in a one-off, to ‘x,’ we can legitimately say the scenario may
be said to describe a ‘semantic’ phenomenon. Grice would freely use ‘semantic,’
and the root for ‘semantics,’ that Grice does use, involves the richest root of
all Grecian roots: the ‘semion.’ Liddell and Scott have “τό σημεῖον,” Ion.

Cat. But the next, De Int. As Arsitotle puts it, an expression is a symbol
(symbolon) or sign (semeion) of an affections or impression (pathematon) of the
soul (psyche). An affection of the soul, of which a word is primarily a sign, are the same for the whole
of mankind, as is also objects (pragmaton) of which the affections is a
representation or likenes, image, or copiy (homoiomaton). [De Int., 1.16a4] while
Grice is NOT concerned about the semantics of utterers meaning (how could he,
when he analyses means in terms of
intends , he is about the semantics of
expression-meaning. Grices second stage (expression meaing) of his
programme about meaning begins with specifications of means as applied to x, a token
of X. He is having Tarski and Davidson in their elaborations of schemata
like ‘p’ ‘means’ that p. ‘Snow is white’ ‘means’ that snow is white,
and stuff! Grice was especially concerned with combinatories, for both unary
and dyadic operators, and with multiple quantifications within a first-order
predicate calculus with identity. Since in Grice’s initial elaboration on
meaning he relies on Stevenson, it is worth exploring how ‘semantics’ and
‘semiotics’ were interpreted by Peirce and the emotivists. Stevenson’s main
source is however in the other place, though, under Stevenson. Semantics –
communication – H. P. Grice, “Implicaturum and Explicature: The basis of
communication” – “Communication and Intention” -- philosophy of language, the
philosophical study of natural language and its workings, particularly of linguistic
meaning and the use of language. A natural language is any one of the thousands
of various tongues that have developed historically among populations of human
beings and have been used for everyday purposes
including English, , Swahili, and Latin
as opposed to the formal and other artificial “languages” invented by
mathematicians, logicians, and computer scientists, such as arithmetic, the
predicate calculus, and LISP or COBOL. There are intermediate cases, e.g.,
Esperanto, Pig Latin, and the sort of “philosophese” that mixes English words
with logical symbols. Contemporary philosophy of language centers on the theory
of meaning, but also includes the theory of reference, the theory of truth,
philosophical pragmatics, and the philosophy of linguistics. The main question
addressed by the theory of meaning is: In virtue of what are certain physical
marks or noises meaningful linguistic expressions, and in virtue of what does
any particular set of marks or noises have the distinctive meaning it does? A
theory of meaning should also give a comprehensive account of the “meaning
phenomena,” or general semantic properties of sentences: synonymy, ambiguity,
entailment, and the like. Some theorists have thought to express these
questions and issues in terms of languageneutral items called propositions: ‘In
virtue of what does a particular set of marks or noises express the proposition
it does?’; cf. ‘ “La neige est blanche” expresses the proposition that snow is
white’, and ‘Synonymous sentences express the same proposition’. On this view,
to understand a sentence is to “grasp” the proposition expressed by that
sentence. But the explanatory role and even the existence of such entities are
disputed. It has often been maintained that certain special sentences are true
solely in virtue of their meanings and/or the meanings of their component
expressions, without regard to what the nonlinguistic world is like ‘No
bachelor is married’; ‘If a thing is blue it is colored’. Such vacuously true
sentences are called analytic. However, Quine and others have disputed whether
there really is such a thing as analyticity. Philosophers have offered a number
of sharply competing hypotheses as to the nature of meaning, including: 1 the
referential view that words mean by standing for things, and that a sentence
means what it does because its parts correspond referentially to the elements
of an actual or possible state of affairs in the world; 2 ideational or
mentalist theories, according to which meanings are ideas or other psychological
phenomena in people’s minds; 3 “use” theories, inspired by Vitters and to a
lesser extent by J. L. Austin: a linguistic expression’s “meaning” is its
conventionally assigned role as a game-piece-like token used in one or more
existing social practices; 4 H. P. Grice’s hypothesis that a sentence’s or
word’s meaning is a function of what audience response a typical utterer would
intend to elicit in uttering it. 5 inferential role theories, as developed by
Wilfrid Sellars out of Carnap’s and Vitters’s views: a sentence’s meaning is
specified by the set of sentences from which it can correctly be inferred and
the set of those which can be inferred from it Sellars himself provided for
“language-entry” and “language-exit” moves as partly constitutive of meaning,
in addition to inferences; 6 verificationism, the view that a sentence’s
meaning is the set of possible experiences that would confirm it or provide
evidence for its truth; 7 the truth-conditional theory: a sentence’s meaning is
the distinctive condition under which it is true, the situation or state of
affairs that, if it obtained, would make the sentence true; 8 the null
hypothesis, or eliminativist view, that “meaning” is a myth and there is no
such thing a radical claim that can stem
either from Quine’s doctrine of the indeterminacy of translation or from
eliminative materialism in the philosophy of mind. Following the original work
of Carnap, Alonzo Church, Hintikka, and Richard Montague in the 0s, the theory
of meaning has made increasing use of “possible worlds”based intensional logic
as an analytical apparatus. Propositions sentence meanings considered as
entities, and truth conditions as in 7 above, are now commonly taken to be
structured sets of possible worlds e.g.,
the set of worlds in which Aristotle’s maternal grandmother hates broccoli. And
the structure imposed on such a set, corresponding to the intuitive constituent
structure of a proposition as the concepts ‘grandmother’ and ‘hate’ are
constituents of the foregoing proposition, accounts for the meaning-properties
of sentences that express the proposition. Theories of meaning can also be
called semantics, as in “Gricean semantics” or “Verificationist semantics,”
though the term is sometimes restricted to referential and/or truth-conditional
theories, which posit meaning-constitutive relations between words and the
nonlinguistic world. Semantics is often contrasted with syntax, the structure
of grammatically permissible ordering relations between words and other words
in well-formed sentences, and with pragmatics, the rules governing the use of
meaningful expressions in particular speech contexts; but linguists have found
that semantic phenomena cannot be kept purely separate either from syntactic or
from pragmatic phenomena. In a still more specialized usage, linguistic
semantics is the detailed study typically within the truth-conditional format
of particular types of construction in particular natural languages, e.g.,
belief-clauses in English or adverbial phrases in Kwakiutl. Linguistic
semantics in that sense is practiced by some philosophers of language, by some
linguists, and occasionally by both working together. Montague grammar and
situation semantics are common formats for such work, both based on intensional
logic. The theory of referenceis pursued whether or not one accepts either the
referential or the truthconditional theory of meaning. Its main question is: In
virtue of what does a linguistic expression designate one or more things in the
world? Prior to theorizing and defining of technical uses, ‘designate’,
‘denote’, and ‘refer’ are used interchangeably. Denoting expressions are
divided into singular terms, which purport to designate particular individual
things, and general terms, which can apply to more than one thing at once.
Singular terms include proper names ‘Cindy’, ‘Bangladesh’, definite
descriptions ‘my brother’, ‘the first baby born in the New World’, and singular
pronouns of various types ‘this’, ‘you’, ‘she’. General terms include common
nouns ‘horse’, ‘trash can’, mass terms ‘water’, ‘graphite’, and plural pronouns
‘they’, ‘those’. The twentieth century’s dominant theory of reference has been
the description theory, the view that linguistic terms refer by expressing
descriptive features or properties, the referent being the item or items that
in fact possess those properties. For example, a definite description does that
directly: ‘My brother’ denotes whatever person does have the property of being
my brother. According to the description theory of proper names, defended most
articulately by Russell, such names express identifying properties indirectly
by abbreviating definite descriptions. A general term such as ‘horse’ was
thought of as expressing a cluster of properties distinctive of horses; and so
forth. But the description theory came under heavy attack in the late 0s, from
Keith Donnellan, Kripke, and Putnam, and was generally abandoned on each of
several grounds, in favor of the causal-historical theory of reference. The
causal-historical idea is that a particular use of a linguistic expression
denotes by being etiologically grounded in the thing or group that is its
referent; a historical causal chain of a certain shape leads backward in time
from the act of referring to the referents. More recently, problems with the
causal-historical theory as originally formulated have led researchers to
backpedal somewhat and incorporate some features of the description theory.
Other views of reference have been advocated as well, particularly analogues of
some of the theories of meaning listed above
chiefly 26 and 8. Modal and propositional-attitude contexts create
special problems in the theory of reference, for referring expressions seem to
alter their normal semantic behavior when they occur within such contexts. Much
ink has been spilled over the question of why and how the substitution of a
term for another term having exactly the same referent can change the
truth-value of a containing modal or propositional-attitude sentence.
Interestingly, the theory of truth historically predates articulate study of
meaning or of reference, for philosophers have always sought the nature of
truth. It has often been thought that a sentence is true in virtue of
expressing a true belief, truth being primarily a property of beliefs rather
than of linguistic entities; but the main theories of truth have also been
applied to sentences directly. The correspondence theory maintains that a
sentence is true in virtue of its elements’ mirroring a fact or actual state of
affairs. The coherence theory instead identifies truth as a relation of the
true sentence to other sentences, usually an epistemic relation. Pragmatic
theories have it that truth is a matter either of practical utility or of
idealized epistemic warrant. Deflationary views, such as the traditional
redundancy theory and D. Grover, J. Camp, and N. D. Belnap’s prosentential
theory, deny that truth comes to anything more important or substantive than
what is already codified in a recursive Tarskian truth-definition for a
language. Pragmatics studies the use of language in context, and the
context-dependence of various aspects of linguistic interpretation. First, one
and the same sentence can express different meanings or propositions from
context to context, owing to ambiguity or to indexicality or both. An ambiguous
sentence has more than one meaning, either because one of its component words
has more than one meaning as ‘bank’ has or because the sentence admits of more
than one possible syntactic analysis ‘Visiting doctors can be tedious’, ‘The
mouse tore up the street’. An indexical sentence can change in truth-value from
context to context owing to the presence of an element whose reference
fluctuates, such as a demonstrative pronoun ‘She told him off yesterday’, ‘It’s
time for that meeting now’. One branch of pragmatics investigates how context
determines a single propositional meaning for a sentence on a particular
occasion of that sentence’s use. Speech act theory is a second branch of
pragmatics that presumes the propositional or “locutionary” meanings of
utterances and studies what J. L. Austin called the illocutionary forces of
those utterances, the distinctive types of linguistic act that are performed by
the speaker in making them. E.g., in uttering ‘I will be there tonight’, a
speaker might be issuing a warning, uttering a threat, making a promise, or
merely offering a prediction, depending on conventional and other social
features of the situation. A crude test of illocutionary force is the “hereby”
criterion: one’s utterance has the force of, say, a warning, if it could fairly
have been paraphrased by the corresponding “explicitly performative” sentence
beginning ‘I hereby warn you that . . .’..Speech act theory interacts to some
extent with semantics, especially in the case of explicit performatives, and it
has some fairly dramatic syntactic effects as well. A third branch of
pragmatics not altogether separate from the second is the theory of
conversation or theory of implicaturum, founded by H. P. Grice. Grice notes
that sentences, when uttered in particular contexts, often generate
“implications” that are not logical consequences of those sentences ‘Is Jones a
good philosopher?’ ’He has very neat
handwriting’. Such implications can usually be identified as what the speaker meant
in uttering her sentence; thus for that reason and others, what Grice calls
utterer’s meaning can diverge sharply from sentence-meaning or “timeless”
meaning. To explain those non-logical implications, Grice offered a now widely
accepted theory of conversational implicaturum. Conversational implicaturums
arise from the interaction of the sentence uttered with mutually shared
background assumptions and certain principles of efficient and cooperative
conversation. The philosophy of linguistics studies the academic discipline of
linguistics, particularly theoretical linguistics considered as a science or
purported science; it examines methodology and fundamental assumptions, and
also tries to incorporate linguists’ findings into the rest of philosophy of language.
Theoretical linguistics concentrates on syntax, and took its contemporary form
in the 0s under Zellig Harris and Chomsky: it seeks to describe each natural
language in terms of a generative grammar for that language, i.e., a set of
recursive rules for combining words that will generate all and only the
“well-formed strings” or grammatical sentences of that language. The set must
be finite and the rules recursive because, while our informationprocessing
resources for recognizing grammatical strings as such are necessarily finite
being subagencies of our brains, there is no limit in any natural language
either to the length of a single grammatical sentence or to the number of
grammatical sentences; a small device must have infinite generative and parsing
capacity. Many grammars work by generating simple “deep structures” a kind of
tree diagram, and then producing multiple “surface structures” as variants of
those deep structures, by means of rules that rearrange their parts. The
surface structures are syntactic parsings of natural-language sentences, and
the deep structures from which they derive encode both basic grammatical
relations between the sentences’ major constituents and, on some theories, the
sentences’ main semantic properties as well; thus, sentences that share a deep
structure will share some fundamental grammatical properties and all or most of
their semantics. As Paul Ziff and Davidson saw in the 0s, the foregoing
syntactic problem and its solution had semantic analogues. From small resources,
human speakers understand compute the
meanings of arbitrarily long and novel
sentences without limit, and almost instantaneously. This ability seems to
require semantic compositionality, the thesis that the meaning of a sentence is
a function of the meanings of its semantic primitives or smallest meaningful
parts, built up by way of syntactic compounding. Compositionality also seems to
be required by learnability, since a normal child can learn an infinitely
complex dialect in at most two years, but must learn semantic primitives one at
a time. A grammar for a natural language is commonly taken to be a piece of
psychology, part of an explanation of speakers’ verbal abilities and behavior.
As such, however, it is a considerable idealization: it is a theory of
speakers’ linguistic “competence” rather than of their actual verbal
performance. The latter distinction is required by the fact that speakers’
considered, reflective judgments of grammatical correctness do not line up very
well with the class of expressions that actually are uttered and understood
unreflectively by those same speakers. Some grammatical sentences are too hard
for speakers to parse quickly; some are too long to finish parsing at all;
speakers commonly utter what they know to be formally ungrammatical strings;
and real speech is usually fragmentary, interspersed with vocalizations, false
starts, and the like. Actual departures from formal grammaticality are ascribed
by linguists to “performance limitations,” i.e., psychological factors such as
memory failure, weak computational capacity, or heedlessness; thus, actual
verbal behavior is to be explained as resulting from the perturbation of
competence by performance limitations. Refs.: The main sources are his lectures on language and reality

holism, a metaphysical thesis about the nature of representation on which the
meaning of a symbol is relative to the entire system of representations
containing it. Thus, a linguistic expression can have meaning only in the
context of a language; a hypothesis can have significance only in the context
of a theory; a concept can have intentionality only in the context of the
belief system. Holism about content has profoundly influenced virtually every
aspect of contemporary theorizing about language and mind, not only in
philosophy, but in linguistics, literary theory, artificial intelligence,
psychology, and cognitive science. Contemporary semantic holists include
Davidson, Quine, Gilbert Harman, Hartry Field, and Searle. Because semantic
holism is a metaphysical and not a semantic thesis, two theorists might agree
about the semantic facts but disagree about semantic holism. So, e.g., nothing
in Tarski’s writings determines whether the semantic facts expressed by the
theorems of an absolute truth semantic atomism semantic holism 829 829 theory are holistic or not. Yet
Davidson, a semantic holist, argued that the correct form for a semantic theory
for a natural language L is an absolute truth theory for L. Semantic theories,
like other theories, need not wear their metaphysical commitments on their
sleeves. Holism has some startling consequences. Consider this. Franklin D.
Roosevelt who died when the United States still had just forty-eight states did
not believe there were fifty states, but I do; semantic holism says that what
‘state’ means in our mouths depends on the totality of our beliefs about
states, including, therefore, our beliefs about how many states there are. It
seems to follow that he and I must mean different things by ‘state’; hence, if
he says “Alaska is not a state” and I say “Alaska is a state” we are not
disagreeing. This line of argument leads to such surprising declarations as
that natural langauges are not, in general, intertranslatable Quine, Saussure;
that there may be no fact of the matter about the meanings of texts Putnam,
Derrida; and that scientific theories that differ in their basic postulates are
“empirically incommensurable” Paul Feyerabend, Kuhn. For those who find these
consequences of semantic holism unpalatable, there are three mutually exclusive
responses: semantic atomism, semantic molecularism, or semantic nihilism.
Semantic atomists hold that the meaning of any representation linguistic,
mental, or otherwise is not determined by the meaning of any other representation.
Historically, Anglo- philosophers in the eighteenth and nineteenth centuries
thought that an idea of an X was about X’s in virtue of this idea’s physically
resembling X’s. Resemblance theories are no longer thought viable, but a number
of contemporary semantic atomists still believe that the basic semantic
relation is between a concept and the things to which it applies, and not one
among concepts themselves. These philosophers include Dretske, Dennis Stampe,
Fodor, and Ruth Millikan. Semantic molecularism, like semantic holism, holds
that the meaning of a representation in a language L is determined by its
relationships to the meanings of other expressions in L, but, unlike holism,
not by its relationships to every other expression in L. Semantic molecularists
are committed to the view, contrary to Quine, that for any expression e in a
language L there is an in-principle way of distinguishing between those
representations in L the meanings of which determine the meaning of e and those
representations in L the meanings of which do not determine the meaning of e.
Traditionally, this inprinciple delimitation is supported by an
analytic/synthetic distinction. Those representations in L that are
meaning-constituting of e are analytically connected to e and those that are
not meaning-constituting are synthetically connected to e. Meaning molecularism
seems to be the most common position among those philosophers who reject
holism. Contemporary meaning molecularists include Michael Devitt, Dummett, Ned
Block, and John Perry. Semantic nihilism is perhaps the most radical response
to the consequences of holism. It is the view that, strictly speaking, there
are no semantic properties. Strictly speaking, there are no mental states;
words lack meanings. At least for scientific purposes and perhaps for other
purposes as well we must abandon the notion that people are moral or rational
agents and that they act out of their beliefs and desires. Semantic nihilists
include among their ranks Patricia and Paul Churchland, Stephen Stich, Dennett,
and, sometimes, Quine. -- semantic
paradoxes, a collection of paradoxes involving the semantic notions of truth,
predication, and definability. The liar paradox is the oldest and most widely
known of these, having been formulated by Eubulides as an objection to
Aristotle’s correspondence theory of truth. In its simplest form, the liar
paradox arises when we try to assess the truth of a sentence or proposition
that asserts its own falsity, e.g.: A Sentence A is not true. It would seem that
sentence A cannot be true, since it can be true only if what it says is the
case, i.e., if it is not true. Thus sentence A is not true. But then, since
this is precisely what it claims, it would seem to be true. Several alternative
forms of the liar paradox have been given their own names. The postcard
paradox, also known as a liar cycle, envisions a postcard with sentence B on
one side and sentence C on the other: B The sentence on the other side of this
card is true. semantic molecularism semantic paradoxes 830 830 C The sentence on the other side of
this card is false. Here, no consistent assignment of truth-values to the pair
of sentences is possible. In the preface paradox, it is imagined that a book
begins with the claim that at least one sentence in the book is false. This
claim is unproblematically true if some later sentence is false, but if the
remainder of the book contains only truths, the initial sentence appears to be
true if and only if false. The preface paradox is one of many examples of
contingent liars, claims that can either have an unproblematic truth-value or
be paradoxical, depending on the truth-values of various other claims in this
case, the remaining sentences in the book. Related to the preface paradox is
Epimenedes’ paradox: Epimenedes, himself from Crete, is said to have claimed
that all Cretans are liars. This claim is paradoxical if interpreted to mean
that Cretans always lie, or if interpreted to mean they sometimes lie and if no
other claim made by Epimenedes was a lie. On the former interpretation, this is
a simple variation of the liar paradox; on the latter, it is a form of
contingent liar. Other semantic paradoxes include Berry’s paradox, Richard’s
paradox, and Grelling’s paradox. The first two involve the notion of definability
of numbers. Berry’s paradox begins by noting that names or descriptions of
integers consist of finite sequences of syllables. Thus the three-syllable
sequence ‘twenty-five’ names 25, and the seven-syllable sequence ‘the sum of
three and seven’ names ten. Now consider the collection of all sequences of
English syllables that are less than nineteen syllables long. Of these, many
are nonsensical ‘bababa’ and some make sense but do not name integers
‘artichoke’, but some do ‘the sum of three and seven’. Since there are only
finitely many English syllables, there are only finitely many of these
sequences, and only finitely many integers named by them. Berry’s paradox
arises when we consider the eighteen-syllable sequence ‘the smallest integer
not nameable in less than nineteen syllables’. This phrase appears to be a
perfectly well-defined description of an integer. But if the phrase names an
integer n, then n is nameable in less than nineteen syllables, and hence is not
described by the phrase. Richard’s paradox constructs a similarly paradoxical
description using what is known as a diagonal construction. Imagine a list of
all finite sequences of letters of the alphabet plus spaces and punctuation,
ordered as in a dictionary. Prune this list so that it contains only English
definitions of real numbers between 0 and 1. Then consider the definition: “Let
r be the real number between 0 and 1 whose kth decimal place is if the kth decimal place of the number named
by the kth member of this list is 1, and 0 otherwise’. This description seems
to define a real number that must be different from any number defined on the
list. For example, r cannot be defined by the 237th member of the list, because
r will differ from that number in at least its 237th decimal place. But if it
indeed defines a real number between 0 and 1, then this description should
itself be on the list. Yet clearly, it cannot define a number different from
the number defined by itself. Apparently, the definition defines a real number
between 0 and 1 if and only if it does not appear on the list of such
definitions. Grelling’s paradox, also known as the paradox of heterologicality,
involves two predicates defined as follows. Say that a predicate is
“autological” if it applies to itself. Thus ‘polysyllabic’ and ‘short’ are
autological, since ‘polysyllabic’ is polysyllabic, and ‘short’ is short. In
contrast, a predicate is “heterological” if and only if it is not autological.
The question is whether the predicate ‘heterological’ is heterological. If our
answer is yes, then ‘heterological’ applies to itself and so is autological, not heterological. But
if our answer is no, then it does not apply to itself and so is heterological, once again
contradicting our answer. The semantic paradoxes have led to important work in
both logic and the philosophy of language, most notably by Russell and Tarski.
Russell developed the ramified theory of types as a unified treatment of all
the semantic paradoxes. Russell’s theory of types avoids the paradoxes by introducing
complex syntactic conditions on formulas and on the definition of new
predicates. In the resulting language, definitions like those used in
formulating Berry’s and Richard’s paradoxes turn out to be ill-formed, since
they quantify over collections of expressions that include themselves,
violating what Russell called the vicious circle principle. The theory of types
also rules out, on syntactic grounds, predicates that apply to themselves, or
to larger expressions containing those very same predicates. In this way, the
liar paradox and Grelling’s paradox cannot be constructed within a language
conforming to the theory of types. Tarski’s attention to the liar paradox made
two fundamental contributions to logic: his development of semantic techniques
for defining the truth predicate for formalized languages and his proof of
Tarski’s theorem. Tarskian semantics avoids the liar paradox by starting with a
formal language, call it L, in which no semantic notions are expressible, and
hence in which the liar paradox cannot be formulated. Then using another
language, known as the metalanguage, Tarski applies recursive techniques to
define the predicate true-in-L, which applies to exactly the true sentences of
the original language L. The liar paradox does not arise in the metalanguage,
because the sentence D Sentence D is not true-in-L. is, if expressible in the
metalanguage, simply true. It is true because D is not a sentence of L, and so
a fortiori not a true sentence of L. A truth predicate for the metalanguage can
then be defined in yet another language, the metametalanguage, and so forth,
resulting in a sequence of consistent truth predicates. Tarski’s theorem uses
the liar paradox to prove a significant result in logic. The theorem states
that the truth predicate for the first-order language of arithmetic is not
definable in arithmetic. That is, if we devise a systematic way of representing
sentences of arithmetic by numbers, then it is impossible to define an
arithmetical predicate that applies to all and only those numbers that
represent true sentences of arithmetic. The theorem is proven by showing that
if such a predicate were definable, we could construct a sentence of arithmetic
that is true if and only if it is not true: an arithmetical version of sentence
A, the liar paradox. Both Russell’s and Tarski’s solutions to the semantic
paradoxes have left many philosophers dissatisfied, since the solutions are
basically prescriptions for constructing languages in which the paradoxes do
not arise. But the fact that paradoxes can be avoided in artificially
constructed languages does not itself give a satisfying explanation of what is
going wrong when the paradoxes are encountered in natural language, or in an
artificial language in which they can be formulated. Most recent work on the
liar paradox, following Kripke’s “Outline of a Theory of Truth” 5, looks at
languages in which the paradox can be formulated, and tries to provide a
consistent account of truth that preserves as much as possible of the intuitive
notion.
Semeiotics: semiological: or is it semiotics? Cf.

‘philosopical biology,’ it may do to use ‘semiology,’ indeed ‘philosophical
semiology,’ here. Oxonian semiotics is
unique. Holloway published his “Language and Intelligence” and everyone was
excited. It is best to see this as Grices psychologism. Grice would rarely use
‘intelligent,’ less so the more pretentious, ‘intelligence,’ as a keyword. If
he is doing it, it is because what he saw as the misuse of it by Ryle and
Holloway. Holloway, a PPE, is a tutorial fellow in philosophy at All Souls. He
acknowledges Ryle as his mentor. (Holloway also quotes from Austin). Grice was
amused that J. N. Findlay, in his review of Holloway’s essay in “Mind,”
compares Holloway to C. W. Morris, and cares to cite the two relevant essay by
Morris: The Foundation in the theory of signs, and Signs, Language, and
Behaviour. Enough for Grice to feel warmly justified in having chosen another
New-World author, Peirce, for his earlier Oxford seminar. Morris studied under
G. H. Mead. But is ‘intelligence’ part of The Griceian Lexicon?Well, Lewis and

tenacity, and such. Grices approach is Pological. If Locke had used
intelligent to refer to Prince Maurices parrot, Grice wants to find criteria
for intelligent as applied to his favourite type of P, rather (intelligent,

‘observation of signs’, the relation of signification involving the three relata
of sign, object, and mind. Semiotic is the science or study of semiosis. The
semiotic of John of Saint Thomas and of Peirce includes two distinct
components: the relation of signification and the classification of signs. The
relation of signification is genuinely triadic and cannot be reduced to the sum
of its three subordinate dyads: sign-object, sign-mind, object-mind. A sign
represents an object to a mind just as A gives a gift to B. Semiosis is not, as
it is often taken to be, a mere compound of a sign-object dyad and a sign-mind
dyad because these dyads lack the essential intentionality that unites mind
with object; similarly, the gift relation involves not just A giving and B
receiving but, crucially, the intention uniting A and B. In the Scholastic
logic of John of Saint Thomas, the sign-object dyad is a categorial relation
secundum esse, that is, an essential relation, falling in Aristotle’s category
of relation, while the sign-mind dyad is a transcendental relation secundum
dici, that is, a relation only in an analogical sense, in a manner of speaking;
thus the formal rationale of semiosis is constituted by the sign-object dyad.
By contrast, in Peirce’s logic, the sign-object dyad and the sign-mind dyad are
each only potential semiosis: thus, the hieroglyphs of ancient Egypt were
merely potential signs until the discovery of the Rosetta Stone, just as a
road-marking was a merely potential sign to the driver who overlooked it.
Classifications of signs typically follow from the logic of semiosis. Thus John
of Saint Thomas divides signs according to their relations to their objects
into natural signs smoke as a sign of fire, customary signs napkins on the
table as a sign that dinner is imminent, and stipulated signs as when a
neologism is coined; he also divides signs according to their relations to a
mind. An instrumental sign must first be cognized as an object before it can
signify e.g., a written word or a symptom; a formal sign, by contrast, directs
the mind to its object without having first been cognized e.g., percepts and
concepts. Formal signs are not that which we cognize but that by which we
cognize. All instrumental signs presuppose the action of formal signs in the
semiosis of cognition. Peirce similarly classified signs into three trichotomies
according to their relations with 1 themselves, 2 their objects, and 3 their
interpretants usually minds; and Charles Morris, who followed Peirce closely,
called the relationship of signs to one another the syntactical dimension of
semiosis, the relationship of signs to their objects the semantical dimension
of semiosis, and the relationship of signs to their interpreters the pragmatic
dimension of semiosis. Refs.: The most specific essay is

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

set-theoretic paradoxes,
a collection of paradoxes that reveal difficulties in certain central notions
of set theory. The best-known of these are Russell’s paradox, Burali-Forti’s
paradox, and Cantor’s paradox. Russell’s paradox, discovered in 1 by Bertrand
Russell, is the simplest and so most problematic of the set-theoretic
paradoxes. Using it, we can derive a contradiction directly from Cantor’s
unrestricted comprehension schema. This schema asserts that for any formula Px
containing x as a free variable, there is a set {x _ Px} whose members are
exactly those objects that satisfy Px. To derive the contradiction, take Px to
be the formula x 1 x, and let z be the set {x _ x 2 x} whose existence is
guaranteed by the comprehension schema. Thus z is the set whose members are
exactly those objects that are not members of themselves. We now ask whether z
is, itself, a member of z. If the answer is yes, then we can conclude that z
must satisfy the criterion of membership in z, i.e., z must not be a member of
z. But if the answer is no, then since z is not a member of itself, it
satisfies the criterion for membership in z, and so z is a member of z. All
modern axiomatizations of set theory avoid Russell’s paradox by restricting the
principles that assert the existence of sets. The simplest restriction replaces
unrestricted comprehension with the separation schema. Separation asserts that,
given any set A and formula Px, there is a set {x 1 A _ Px}, whose members are
exactly those members of A that satisfy Px. If we now take Px to be the formula
x 2 x, then separation guarantees the existence of a set zA % {x 1 A _ x 2 x}.
We can then use Russell’s reasoning to prove the result that zA cannot be a
member of the original set A. If it were a member of A, then we could prove
that it is a member of itself if and only if it is not a member of itself.
Hence it is not a member of A. But this result is not problematic, and so the
paradox is avoided. The Burali-Forte paradox and Cantor’s paradox are sometimes
known as paradoxes of size, since they show that some collections are too large
to be considered sets. The Burali-Forte paradox, discovered by Cesare
Burali-Forte, is concerned with the set of all ordinal numbers. In Cantor’s set
theory, an ordinal number can be assigned to any well-ordered set. A set is
wellordered if every subset of the set has a least element. But Cantor’s set
theory also guarantees the existence of the set of all ordinals, again due to
the unrestricted comprehension schema. This set of ordinals is well-ordered,
and so can be associated with an ordinal number. But it can be shown that the
associated ordinal is greater than any ordinal in the set, hence greater than
any ordinal number. Cantor’s paradox involves the cardinality of the set of all
sets. Cardinality is another notion of size used in set theory: a set A is said
to have greater cardinality than a set B if and only if B can be mapped
one-to-one onto a subset of A but A cannot be so mapped onto B or any of its
subsets. One of Cantor’s fundamental results was that the set of all subsets of
a set A known as the power set of A has greater cardinality than the set A.
Applying this result to the set V of all sets, we can conclude that the power
set of V has greater cardinality than V. But every set in the power set of V is
also in V since V contains all sets, and so the power set of V cannot have
greater cardinality than V. We thus have a contradiction. Like Russell’s
paradox, both of these paradoxes result from the unrestricted comprehension
schema, and are avoided by replacing it with weaker set-existence principles.
Various principles stronger than the separation schema are needed to get a
reasonable set theory, and many alternative axiomatizations have been proposed.
But the lesson of these paradoxes is that no setexistence principle can entail
the existence of the Russell set, the set of all ordinals, or the set of all
sets, on pain of contradiction.
set theory – “I
distinguish between a class and a set, but Strawson does not.” – Grice -- the study of collections, ranging from
familiar examples like a set of encyclopedias or a deck of cards to
mathematical examples like the set of natural numbers or the set of points on a
line or the set of functions from a set A to another set B. Sets can be specified
in two basic ways: by a list e.g., {0, 2, 4, 6, 8} and as the extension of a
property e.g., {x _ x is an even natural number less than 10}, where this is
read ‘the set of all x such that x is an even natural number less than 10’. The
most fundamental relation in set theory is membership, as in ‘2 is a member of
the set of even natural numbers’ in symbols: 2 1 {x _ x is an even natural
number}. Membership is determinate, i.e., any candidate for membership in a
given set is either in the set or not in the set, with no room for vagueness or
ambiguity. A set’s identity is completely determined by its members or elements
i.e., sets are extensional rather than intensional. Thus {x _ x is human} is
the same set as {x _ x is a featherless biped} because they have the same
members. The smallest set possible is the empty or null set, the set with no
members. There cannot be more than one empty set, by extensionality. It can be
specified, e.g., as {x _ x & x}, but it is most often symbolized as / or {
}. A set A is called a subset of a set B and B a superset of A if every member
of A is also a member of B; in symbols, A 0 B. So, the set of even natural
numbers is a subset of the set of all natural numbers, and any set is a
superset of the empty set. The union of two sets A and B is the set whose
members are the members of A and the members of B in symbols, A 4 B % {x _ x 1 A or x 1 B} so the union of the set of even natural
numbers and the set of odd natural numbers is the set of all natural numbers.
The intersection of two sets A and B is the set whose members are common to
both A and B in symbols, A 3 B % {x _ x
1 A and x 1 B} so the intersection of
the set of even natural numbers and the set of prime natural numbers is the
singleton set {2}, whose only member is the number 2. Two sets whose
intersection is empty are called disjoint, e.g., the set of even natural
numbers and the set of odd natural numbers. Finally, the difference between a
set A and a set B is the set whose members are members of A but not members of
B in symbols, A B % {x _ x 1 A and x 2 B} so the set of odd numbers between 5 and 20
minus the set of prime natural numbers is {9, 15}. By extensionality, the order
in which the members of a set are listed is unimportant, i.e., {1, 2, 3} % {2,
3, 1}. To introduce the concept of ordering, we need the notion of the ordered
pair of a and b in symbols, a, b or .
All that is essential to ordered pairs is that two of them are equal only when
their first entries are equal and their second entries are equal. Various sets
can be used to simulate this behavior, but the version most commonly used is
the Kuratowski ordered pair: a, b is defined to be {{a}, {a, b}}. On this
definition, it can indeed be proved that a, b % c, d if and only if a % c and b
% d. The Cartesian product of two sets A and B is the set of all ordered pairs
whose first entry is in A and whose second entry is B in symbols, A $ B % {x _ x % a, b for some a
1 A and some b 1 B}. This set-theoretic reflection principles set theory
836 836 same technique can be used to
form ordered triples a, b, c % a, b, c;
ordered fourtuples a, b, c, d % a, b, c,
d; and by extension, ordered n-tuples for all finite n. Using only these simple
building blocks, substitutes for all the objects of classical mathematics can
be constructed inside set theory. For example, a relation is defined as a set
of ordered pairs so the successor
relation among natural numbers becomes {0, 1, 1, 2, 2, 3 . . . } and a function is a relation containing no
distinct ordered pairs of the form a, b and a, c so the successor relation is a function. The
natural numbers themselves can be identified with various sequences of sets,
the most common of which are finite von Neumann ordinal numbers: /, {/}, {/,
{/}, {/}, {/}, {/, {/}}}, . . . . On this definition, 0 % /, 1 % {/}, 2 % {/,
{/}}, etc., each number n has n members, the successor of n is n 4 {n}, and n ‹
m if and only if n 1 m. Addition and multiplication can be defined for these
numbers, and the Peano axioms proved from the axioms of set theory; see below.
Negative, rational, real, and complex numbers, geometric spaces, and more
esoteric mathematical objects can all be identified with sets, and the standard
theorems about them proved. In this sense, set theory provides a foundation for
mathematics. Historically, the theory of sets arose in the late nineteenth
century. In his work on the foundations of arithmetic, Frege identified the
natural numbers with the extensions of certain concepts; e.g., the number two
is the set of all concepts C under which two things fall in symbols, 2 % {x _ x is a concept, and
there are distinct things a and b which fall under x, and anything that falls
under x is either a or b}. Cantor was led to consider complex sets of points in
the pursuit of a question in the theory of trigonometric series. To describe
the properties of these sets, Cantor introduced infinite ordinal numbers after
the finite ordinals described above. The first of these, w, is {0, 1, 2, . .
.}, now understood in von Neumann’s terms as the set of all finite ordinals.
After w, the successor function yields w ! 1 % w 4 {w} % {0, 1, 2, . . . n, n +
1, . . . , w}, then w ! 2 % w ! 1 ! 1 % {0, 1, 2, . . . , w , w ! 1}, w ! 3 % w
! 2 ! 1 % {0, 1, 2, . . . , w, w ! 1, w ! 2}, and so on; after all these comes
w ! w % {0, 1, 2, . . . , w, w ! 1, w ! 2, . . . , w ! n, w ! n ! 1, . . .},
and the process begins again. The ordinal numbers are designed to label the
positions in an ordering. Consider, e.g., a reordering of the natural numbers
in which the odd numbers are placed after the evens: 0, 2, 4, 6, . . . 1, 3, 5,
7, . . . . The number 4 is in the third position of this sequence, and the
number 5 is in the w + 2nd. But finite numbers also perform a cardinal
function; they tell us how many so-andso’s there are. Here the infinite
ordinals are less effective. The natural numbers in their usual order have the
same structure as w, but when they are ordered as above, with the evens before
the odds, they take on the structure of a much larger ordinal, w ! w. But the
answer to the question, How many natural numbers are there? should be the same
no matter how they are arranged. Thus, the transfinite ordinals do not provide
a stable measure of the size of an infinite set. When are two infinite sets of
the same size? On the one hand, the infinite set of even natural numbers seems
clearly smaller than the set of all natural numbers; on the other hand, these
two sets can be brought into one-to-one correspondence via the mapping that
matches 0 to 0, 1 to 2, 2 to 4, 3 to 6, and in general, n to 2n. This puzzle
had troubled mathematicians as far back as Galileo, but Cantor took the
existence of a oneto-one correspondence between two sets A and B as the
definition of ‘A is the same size as B’. This coincides with our usual
understanding for finite sets, and it implies that the set of even natural
numbers and the set of all natural numbers and w ! 1 and w! 2 and w ! w and w !
w and many more all have the same size. Such infinite sets are called
countable, and the number of their elements, the first infinite cardinal
number, is F0. Cantor also showed that the set of all subsets of a set A has a
size larger than A itself, so there are infinite cardinals greater than F0,
namely F1, F2, and so on. Unfortunately, the early set theories were prone to
paradoxes. The most famous of these, Russell’s paradox, arises from
consideration of the set R of all sets that are not members of themselves: is R
1 R? If it is, it isn’t, and if it isn’t, it is. The Burali-Forti paradox
involves the set W of all ordinals: W itself qualifies as an ordinal, so W 1 W,
i.e., W ‹ W. Similar difficulties surface with the set of all cardinal numbers
and the set of all sets. At fault in all these cases is a seemingly innocuous
principle of unlimited comprehension: for any property P, there is a set {x _ x
has P}. Just after the turn of the century, Zermelo undertook to systematize
set theory by codifying its practice in a series of axioms from which the known
derivations of the paradoxes could not be carried out. He proposed the axioms
of extensionality two sets with the same members are the same; pairing for any
a and b, there is a set {a, b}; separation for any set A and property P, there
is a set {x _ x 1 A and x has P}; power set for any set A, there is a set {x _
x0 A}; union for any set of sets F, there is a set {x _ x 1 A for some A 1
F} this yields A 4 B, when F % {A, B}
and {A, B} comes from A and B by pairing; infinity w exists; and choice for any
set of non-empty sets, there is a set that contains exactly one member from
each. The axiom of choice has a vast number of equivalents, including the
well-ordering theorem every set can be
well-ordered and Zorn’s lemma if every chain in a partially ordered set has
an upper bound, then the set has a maximal element. The axiom of separation
limits that of unlimited comprehension by requiring a previously given set A
from which members are separated by the property P; thus troublesome sets like
Russell’s that attempt to collect absolutely all things with P cannot be
formed. The most controversial of Zermelo’s axioms at the time was that of
choice, because it posits the existence of a choice set a set that “chooses” one from each of
possibly infinitely many non-empty sets
without giving any rule for making the choices. For various
philosophical and practical reasons, it is now accepted without much debate.
Fraenkel and Skolem later formalized the axiom of replacement if A is a set,
and every member a of A is replaced by some b, then there is a set containing
all the b’s, and Skolem made both replacement and separation more precise by
expressing them as schemata of first-order logic. The final axiom of the
contemporary theory is foundation, which guarantees that sets are formed in a
series of stages called the iterative hierarchy begin with some non-sets, then
form all possible sets of these, then form all possible sets of the things
formed so far, then form all possible sets of these, and so on. This iterative
picture of sets built up in stages contrasts with the older notion of the
extension of a concept; these are sometimes called the mathematical and the
logical notions of collection, respectively. The early controversy over the
paradoxes and the axiom of choice can be traced to the lack of a clear distinction
between these at the time. Zermelo’s first five axioms all but choice plus
foundation form a system usually called Z; ZC is Z with choice added. Z plus
replacement is ZF, for Zermelo-Fraenkel, and adding choice makes ZFC, the
theory of sets in most widespread use today. The consistency of ZFC cannot be
proved by standard mathematical means, but decades of experience with the
system and the strong intuitive picture provided by the iterative conception
suggest that it is. Though ZFC is strong enough for all standard mathematics,
it is not enough to answer some natural set-theoretic questions e.g., the
continuum problem. This has led to a search for new axioms, such as large
cardinal assumptions, but no consensus on these additional principles has yet
been reached.
Sextus Empiricus, the
sixth son of Empiricus the Elder – “My five brothers were not philosophers” -- Grecian
Skeptic philosopher whose writings are the chief source of our knowledge about
the extreme Skeptic view, Pyrrhonism. Practically nothing is known about him as
a person. He was apparently a medical doctor and a teacher in a Skeptical
school, probably in Alexandria. What has survived are his Hypotoposes, Outlines
of Pyrrhonism, and a series of Skeptical critiques, Against the Dogmatists, questioning
the premises and conclusions in many disciplines, such as physics, mathematics,
rhetoric, and ethics. In these works, Sextus summarized and organized the views
of Skeptical arguers before him. The Outlines starts with an attempt to
indicate what Skepticism is, to explain the terminology employed by the
Skeptics, how Pyrrhonian Skepticism differs from other so-called Skeptical
views, and how the usual answers to Skepticism are rebutted. Sextus points out
that the main Hellenistic philosophies, Stoicism, Epicureanism, and Academic
Skepticism which is presented as a negative dogmatism, claimed that they would
bring the adherent peace of mind, ataraxia. Unfortunately the dogmatic adherent
would only become more perturbed by seeing the Skeptical objections that could
be brought against his or her view. Then, by suspending judgment, epoche, one
would find the tranquillity being sought. Pyrrhonian Skepticism is a kind of
mental hygiene or therapy that cures one of dogmatism or rashness. It is like a
purge that cleans out foul matter as well as itself. To bring about this state
of affairs there are sets of Skeptical arguments that should bring one to
suspense of judgment. The first set are the ten tropes of the earlier Skeptic,
Anesidemus. The next are the five tropes about causality. And lastly are the
tropes about the criterion of knowledge. The ten tropes stress the variability
of sense experience among men and animals, among men, and within one
individual. The varying and conflicting experiences present conflicts about
what the perceived object is like. Any attempt to judge beyond appearances, to
ascertain that which is non-evident, requires some way of choosing what data to
accept. This requires a criterion. Since there is disagreement about what
criterion to employ, we need a criterion of a criterion, and so on. Either we
accept an arbitrary criterion or we get into an infinite regress. Similarly if
we try to prove anything, we need a criterion of what constitutes a proof. If
we offer a proof of a theory of proof, this will be circular reasoning, or end
up in another infinite regress. Sextus devotes most of his discussion to
challenging Stoic logic, which claimed that evident signs could reveal what is
non-evident. There might be signs that suggested what is temporarily
non-evident, such as smoke indicating that there is a fire, but any supposed
linkage between evident signs and what is non-evident can be challenged and
questioned. Sextus then applies the groups of Skeptical arguments to various
specific subjects physics, mathematics,
music, grammar, ethics showing that one
should suspend judgment on any knowledge claims in these areas. Sextus denies
that he is saying any of this dogmatically: he is just stating how he feels at
given moments. He hopes that dogmatists sick with a disease, rashness, will be
cured and led to tranquillity no matter how good or bad the Skeptical arguments
might be.
Shaftesbury, Lord, in
full, Third Earl of Shaftesbury, title of Anthony Ashley Cooper, English
philosopher and politician who originated the moral sense theory. He was born
at Wimborne St. Giles, Dorsetshire. As a Country Whig he served in the House of
Commons for three years and later, as earl, monitored meetings of the House of
Lords. Shaftesbury introduced into British moral philosophy the notion of a
moral sense, a mental faculty unique to human beings, involving reflection and
feeling and constituting their ability to discern right and wrong. He sometimes
represents the moral sense as analogous to a purported aesthetic sense, a
special capacity by which we perceive, through our emotions, the proportions
and harmonies of which, on his Platonic view, beauty is composed. For
Shaftesbury, every creature has a “private good or interest,” an end to which
it is naturally disposed by its constitution. But there are other goods as
well notably, the public good and the
good without qualification of a sentient being. An individual creature’s
goodness is defined by the tendency of its “natural affections” to contribute
to the “universal system” of nature of which it is a part i.e., their tendency to promote the public
good. Because human beings can reflect on actions and affections, including
their own and others’, they experience emotional responses not only to physical
stimuli but to these mental objects as well e.g., to the thought of one’s
compassion or kindness. Thus, they are capable of perceiving and acquiring through their actions a particular species of goodness, namely,
virtue. In the virtuous person, the person of integrity, natural appetites and
affections are in harmony with each other wherein lies her private good and in
harmony with the public interest. Shaftesbury’s attempted reconciliation of
selflove and benevolence is in part a response to the egoism of Hobbes, who
argued that everyone is in fact motivated by self-interest. His defining
morality in terms of psychological and public harmony is also a reaction to the
divine voluntarism of his former tutor, Locke, who held that the laws of nature
and morality issue from the will of God. On Shaftesbury’s view, morality exists
independently of religion, but belief in God serves to produce the highest
degree of virtue by nurturing a love for the universal system. Shaftesbury’s
theory led to a general refinement of eighteenth-century ideas about moral
feelings; a theory of the moral sense emerged, whereby sentiments are under certain conditions perceptions of, or constitutive of, right and
wrong. In addition to several essays collected in three volumes under the title
Characteristics of Men, Manners, Opinions, Times second edition, 1714,
Shaftesbury also wrote stoical moral and religious meditations reminiscent of
Epictetus and Marcus Aurelius. His ideas on moral sentiments exercised
considerable influence on the ethical theories of Hutcheson and Hume, who later
worked out in detail their own accounts of the moral sense.
Sheffer stroke – see
abdicatum, Grice, “Negation and privation” and “Lectures on negation” -- also
called alternative denial, a binary truth-functor represented by the symbol
‘_’, the logical force of which can be expressed contextually in terms of ‘-’
and ‘&’ by the following definition: p_q % Df -p & q. The importance of
the Sheffer stroke lies in the fact that it by itself can express any well-formed
expression of truth-functional logic. Thus, since {-,7} forms an expressively
complete set, defining -p as p_p and p 7 q as p_p _q_q provides for the
possibility of a further reduction of primitive functors to one. This system of
symbols is commonly called the stroke notation.
Shepherd, Mary d.1847,
Scottish philosopher whose main philosophical works are An Essay on the
Relation of Cause and Effect 1824 and Essays on the Perception of an External
Universe 1827. The first addresses what she takes to be the skeptical
consequences of Hume’s account of causation, but a second target is the use
William Lawrence 17831867 made of Hume’s associative account of causation to
argue that mental functions are reducible to physiological ones. The second
work focuses on Hume’s alleged skepticism with regard to the existence of the
external world, but she is also concerned to distinguish her position from
Berkeley’s. Shepherd was drawn into a public controversy with John Fearn, who
published some remarks she had sent him on a book of his, together with his
extensive reply. Shepherd replied in an article in Fraser’s magazine 1832,
“Lady Mary Shepherd’s Metaphysics,” which deftly refuted Fearn’s rather
condescending attack.
Shyreswood -- Sherwood,
William, also called William Shyreswood, English logician who taught logic at
Oxford and at Paris between 1235 and 1250. He was the earliest of the three
great “summulist” writers, the other two whom he influenced strongly being
Peter of Spain and Lambert of Auxerre. His main works are “Introductiones in
Logicam,” “Syncategoremata,” “De insolubilibus,” and “Obligationes.” Some
serious doubts have recently arisen about the authorship of the latter work.
Since M. Grabmann published Sherwood’s Introductiones, philosophers have paid
considerable attention to this seminal Griceian. While the first part of
Introductiones offer the basic ideas of Aristotle’s Organon, and the latter
part neatly lays out the Sophistical Refutations, the final tract expounds the doctrine
of the four properties of a term. First, signification. Second, supposition.
Third, conjunction, Fourth, appellation -- hence the label ‘terminist’ for this
sort of logic. These logico-semantic discussions, together with the discussions
of syncategorematic words, constitute the “logica moderna,” (Grice’s
‘mdoernism’) as opposed to the more strictly Aristotelian contents of the
earlier logica vetus (Grice’s neo-traditionalism) and logica nova (“It took me
quite a while to explain to Strawson the distinction between ‘logica nova’ and
‘logica moderna,’ only to have him tell me, “worry not, Grice – I’ll be into
‘logica vetus’ anyways!””. The doctrine of properties of terms and the analysis
of syncategorematic terms, especially those of ‘all’ (or every) ‘no’ (or not or
it is not the case) and ‘nothing’, ‘only’, ‘not’, ‘begins’ and ‘ceases (to eat
iron) ‘necessarily’, ‘if’ (Latin ‘si,’ Grecian ‘ei’), ‘and’ (Latin ‘et’,
Grecian ‘kai’) and ‘or’ (Latin ‘vel’) may be said to constitute Sherwood’s or
Shyrewood’s philosophy of logic. Shyrewood not only distinguishes categorematic
descriptive and syncategorematic logical words but also shows how some terms
are used categorematically in some contexts and syncategorematically in others
– “he doesn’t explain which, and that’s one big map in his opus.”– Grice. He
recognizes the importance of the order of words (hence Grice, ‘be orderly’) and
of the scope of logical functors; he also anticipates the variety of composite
and divided senses of propositions. Obligationes, if indeed his, attempts to
state conditions under which a formal disputation may take place. De
Insolubilibus deals with paradoxes of self-reference and with ways of solving
them. Understanding Sherwood’s logic is important for understanding the later
medieval developments of logica moderna down to Occam whom Grice laughed at
(“modified Occam’s razor.”).
ship of Theseus, the ship
of the Grecian hero Theseus, which, according to Plutarch “Life of Theseus,”
23, the Athenians preserved by gradually replacing its timbers. A classic debate
ensued concerning identity over time. Suppose a ship’s timbers are replaced one
by one over a period of time; at what point, if any, does it cease to be the
same ship? What if the ship’s timbers, on removal, are used to build a new
ship, identical in structure with the first: which ship has the best claim to
be the original ship?
Shpet, Gustav Gustavovich
18797, leading Russian phenomenologist and highly regarded student and friend
of Husserl. He played a major role in the development of phenomenology in
Russia prior to the revolution. Graduating from Kiev in 6, Shpet accompanied his mentor Chelpanov
to Moscow in 7, commencing graduate studies at Moscow M.A., 0; Ph.D., 6. He attended Husserl’s
seminars at Göttingen during 213, out of which developed a continuing
friendship between the two, recorded in correspondence extending through 8. In
4 Shpet published a meditation, Iavlenie i smysl Appearance and Sense, inspired
by Husserl’s Logical Investigations and, especially, Ideas I, which had
appeared in 3. Between 4 and 7 he published six additional books on such
disparate topics as the concept of history, Herzen, Russian philosophy,
aesthetics, ethnic psychology, and language. He founded and edited the
philosophical yearbook Mysl’ i slovo Thought and Word between 8 and 1,
publishing an important article on skepticism in it. He was arrested in 5 and
sentenced to internal exile. Under these conditions he completed a fine new
translation of Hegel’s Phenomenology into Russian, which was published in 9. He
was executed in November 7. .
Sidgwick: h. English
philosopher, economist, and educator. Best known for The Methods of Ethics1874,
he also wrote the still valuable Outlines of the History of Ethics 6, as well
as studies of economics, politics, literature, and alleged psychic phenomena.
He was deeply involved in the founding of the first for women at Cambridge , where he was a
professor. In the Methods Sidgwick tried to assess the rationality of the main
ways in which ordinary people go about making moral decisions. He thought that
our common “methods of ethics” fall into three main patterns. One is
articulated by the philosophical theory known as intuitionism. This is the view
that we can just see straight off either what particular act is right or what
binding rule or general principle we ought to follow. Another common method is
spelled out by philosophical egoism, the view that we ought in each act to get
as much good as we can for ourselves. The third widely used method is
represented by utilitarianism, the view that we ought in each case to bring
about as much good as possible for everyone affected. Can any or all of the
methods prescribed by these views be rationally defended? And how are they
related to one another? By framing his philosophical questions in these terms,
Sidgwick made it centrally important to examine the chief philosophical
theories of morality in the light of the commonsense morals of his time. He
thought that no theory wildly at odds with commonsense morality would be
acceptable. Intuitionism, a theory originating with Butler, transmitted by
Reid, and most systematically expounded during the Victorian era by Whewell,
was widely held to be the best available defense of Christian morals. Egoism
was thought by many to be the clearest pattern of practical rationality and was
frequently said to be compatible with Christianity. And J. S. Mill had argued
that utilitarianism was both rational and in accord with common sense. But
whatever their relation to ordinary morality, the theories seemed to be
seriously at odds with one another. Examining all the chief commonsense
precepts and rules of morality, such as that promises ought to be kept,
Sidgwick argued that none is truly self-evident or intuitively certain. Each
fails to guide us at certain points where we expect it to answer our practical
questions. Utilitarianism, he found, could provide a complicated method for
filling these gaps. But what ultimately justifies utilitarianism is certain
very general axioms seen intuitively to be true. Among them are the principles
that what is right in one case must be right in any similar case, and that we
ought to aim at good generally, not just at some particular part of it. Thus
intuitionism and utilitarianism can be reconciled. When taken together they yield
a complete and justifiable method of ethics that is in accord with common
sense. What then of egoism? It can provide as complete a method as
utilitarianism, and it also involves a self-evident axiom. But its results
often contradict those of utilitarianism. Hence there is a serious problem. The
method that instructs us to act always for the good generally and the method
that tells one to act solely for one’s own good are equally rational. Since the
two methods give contradictory directions, while each method rests on
self-evident axioms, it seems that practical reason is fundamentally
incoherent. Sidgwick could see no way to solve the problem. Sidgwick’s bleak
conclusion has not been generally accepted, but his Methods is widely viewed as
one of the best works of moral philosophy ever written. His account of
classical utilitarianism is unsurpassed. His discussions of the general status
of morality and of particular moral concepts are enduring models of clarity and
acumen. His insights about the relations between egoism and utilitarianism have
stimulated much valuable research. And his way of framing moral problems, by
asking about the relations between commonsense beliefs and the best available
theories, has set much of the agenda for twentiethcentury ethics.
Siger of Brabant, philosopher,
an activist in the philosophical and political struggles both within the arts
faculty and between arts and theology at Paris during the 1260s and 1270s. He
is usually regarded as a leader of a “radical Aristotelianism” that owed much
to Liber de causis, to Avicenna, and to Averroes. He taught that everything
originates through a series of emanations from a first cause. The world and
each species including the human species are eternal. Human beings share a
single active intellect. There is no good reason to think that Siger advanced
the view that there was a double truth, one in theology and another in natural
philosophy. It is difficult to distinguish Siger’s own views from those he
attributes to “the Philosophers” and thus to know the extent to which he held
the heterodox views he taught as the best interpretation of the prescribed
texts in the arts curriculum. In any case, Siger was summoned before the Inquisition in 1276, but fled Paris. He was
never convicted of heresy, but it seems that the condemnations at Paris in 1277
were partially directed at his teaching. He was stabbed to death by his clerk
in Orvieto then the papal seat in 1284. .
signatum: Cf. “to sign” as a verb – from French. Grice uses
designatum, too – but more specifically within the ‘propositio’ as a compound
of a subjectum and a predicatum. The subject-item indicates a thing; and the
predicate-item designates a property. As Grice notes, there is a distinction
between Aristotle’s use, in De Int., of ‘sumbolon,’ for which Aristotle
sometimes means ‘semeion,’ and their Roman counterparts, ‘signum’ sounds otiose
enough. But ‘significo’ does not. There is this –fico thing that sounds
obtrusive. The Romans, however, were able to distinguish between ‘make a sign,’
and just ‘signal.’ The point is important when Grice tries to apply the
Graeco-Roman philosophical terminology to a lexeme which does not belong in
there: “mean.” His example is someone in pain, uttering “Oh.” If he later gains
voluntary control, by uttering “Oh” he means that he is in pain, and even at a
later stage, provided he learns ‘lupe,’ he may utter the expression which is
somewhat correlated in a non-iconic fashion with something which iconically is
a vehicle for U to mean that he is in pain. In this way, in a
communication-system, a communication-device, such as “Oh” does for the state
of affairs something that the state of affairs cannot do for itself, govern the
addresee’s thoughts and behaviour (very much as the Oxfordshire cricket team
does for Oxfordshire what Oxfordshire cannot do for herself, viz. to engage in
a game of cricket. There’s rae-presentatum, for you! Short and Lewis have

significatum: or better ‘signatum.’ Grice knew that in old Roman,
signatum was intransitive, as originally ‘significatum’ was – “He is
signifying,” i. e. making signs. In the Middle Ages it was applied to ‘utens’
of this or that expression, as was an actum, ‘agitur,’ Thus an expression was
not said to ‘signify’ in the same way. Grice plays with the
expression-communication distinction. When dealing with a lexeme that does NOT
belong in the Graeco-Roman tradition, that of “mean,” he is never sure. His
doubts were hightlighted in essays on “Grice without an audience.” While Grice
explicitly says that a ‘word’ is not a sign, he would use ‘signify’ at a later
stage, including the implicaturum as part of the significatum. There is indeed
an entry for signĭfĭcātĭo, f. significare. L and S render it, unhelpfully,
as “a pointing out, indicating, denoting, signifying; an
expression, indication, mark, sign, token, = indicium,
signum, ἐπισημασία, etc., freq. and class. As with Stevenson’s ‘communico,’
Grice goes sraight to ‘signĭfĭco,’ also dep. “signĭfĭcor,” f.
‘significare,’ from signum-facere, to make sign, signum-facio, I make sign,
which L and S render as to signify, which is perhaps not too helpful. Grice, if
not the Grecians, knew that. Strictly, L and S render significare as to show by
signs; to show, point out, express, publish, make known, indicate; to intimate,
notify, signify, etc. Note that the cognate signify almost comes last, but not
least, if not first. Enough to want to coin a word to do duty for them all.
Which is what Grice (and the Grecians) can, but the old Romans cannot, with
mean. If that above were not enough, L and S go on, also, to betoken,
prognosticate, foreshow, portend, mean (syn. praedico), as in to betoken a
change of weather (post-Aug.): “ventus Africus tempestatem significat,
etc.,”cf. Grice on those dark clouds mean a storm is coming. Short
and Lewis go on, to say that significare may be rendered as to call, name; to
mean, import, signify. Hence, ‘signĭfĭcans,’ in rhet. lang., of speech, full
of meaning, expressive, significant; graphic, distinct, clear: adv.:
signĭfĭcanter, clearly, distinctly, expressly, significantly, graphically:
“breviter ac significanter ordinem rei protulisse;” “rem indicare (with
proprie),” “dicere (with ornate),” “apertius, significantius dignitatem alicujus
defendere,” “narrare,”“disponere,” “appellare aliquid (with consignatius);”
“dicere (with probabilius).” -- signifier, a vocal sound or a written symbol. The
concept owes its modern formulation to the Swiss linguist Saussure. Rather than
using the older conception of sign and referent, he divided the sign itself
into two interrelated parts, a signifier and a signified. The signified is the
concept and the signifier is either a vocal sound or writing. The relation
between the two, according to Saussure, is entirely arbitrary, in that
signifiers tend to vary with different languages. We can utter or write
‘vache’, ‘cow’, or ‘vaca’, depending on our native language, and still come up
with the same signified i.e., concept.
Simmel, Georg 18588, G.
philosopher and one of the founders of sociology as a distinct discipline. Born
and educated in Berlin, he was a popular lecturer at its university. But the
unorthodoxy of his interests and unprofessional writing style probably kept him
from being offered a regular professorship until 4, and then only at the
provincial of Strasbourg. He died four
years later. His writings ranged from conventional philosophical topics with books on ethics, philosophy of history,
education, religion, and the philosophers Kant, Schopenhauer, and
Nietzsche to books on Rembrandt, Goethe,
and the philosophy of money. He wrote numerous essays on various artists and
poets, on different cities, and on such themes as love, adventure, shame, and
on being a stranger, as well as on many specifically sociological topics.
Simmel was regarded as a Kulturphilosoph who meditated on his themes in an
insightful and digressive rather than scholarly and systematic style. Though
late in life he sketched a unifying Lebensphilosophie philosophy of life that
considers all works and structures of culture as products of different forms of
human experience, Simmel has remained of interest primarily for a multiplicity
of insights into specific topics.
Simplicius sixth century
A.D., Grecian Neoplatonist philosopher born in Cilicia on the southeast coast
of modern Turkey. His surviving works are extensive commentaries on Aristotle’s
On the Heavens, Physics, and Categories, and on the Encheiridion of Epictetus.
The authenticity of the commentary on Aristotle’s On the Soul attributed to
Simplicius has been disputed. He studied with Ammonius in Alexandria, and with
Damascius, the last known head of the Platonist school in Athens. Justinian
closed the school in 529. Two or three years later a group of philosophers,
including Damascius and Simplicius, visited the court of the Sassanian king
Khosrow I Chosroes but soon returned to the Byzantine Empire under a guarantee
of their right to maintain their own beliefs. It is generally agreed that most,
if not all, of Simplicius’s extant works date from the period after his stay
with Khosrow. But there is no consensus about where Simplicius spent his last
years both Athens and Harran have been proposed recently, or whether he resumed
teaching philosophy; his commentaries, unlike most of the others that survive
from that period, are scholarly treatises rather than classroom expositions.
Simplicius’s Aristotle commentaries are the most valuable extant works in the
genre. He is our source for many of the fragments of the preSocratic
philosophers, and he frequently invokes material from now-lost commentaries and
philosophical works. He is a deeply committed Neoplatonist, convinced that
there is no serious conflict between the philosophies of Plato and Aristotle.
The view of earlier scholars that his Encheiridion commentary embodies a more
moderate Platonism associated with Alexandria is now generally rejected.
Simplicius’s virulent defense of the eternity of the world in response to the
attack of the Christian John Philoponus illustrates the intellectual vitality
of paganism at a time when the Mediterranean world had been officially
Christian for about three centuries.
simulation theory, the
view that one represents the mental activities and processes of others by
mentally simulating them, i.e., generating similar activities and processes in
oneself. By simulating them, one can anticipate their product or outcome; or,
where this is already known, test hypotheses about their starting point. For
example, one anticipates the product of another’s theoretical or practical
inferences from given premises by making inferences from the same premises
oneself; or, knowing what the product is, one retroduces the premises. In the
case of practical reasoning, to reason from the same premises would typically
require indexical adjustments, such as shifts in spatial, temporal, and
personal “point of view,” to place oneself in the other’s physical and
epistemic situation insofar as it differs from one’s own. One may also compensate
for the other’s reasoning capacity and level of expertise, if possible, or
modify one’s character and outlook as an actor might, to fit the other’s
background. Such adjustments, even when insufficient for making decisions in
the role of the other, allow one to discriminate between action options likely
to be attractive or unattractive to the agent. One would be prepared for the
former actions and surprised by the latter. The simulation theory is usually
considered an alternative to an assumption sometimes called the “theory theory”
that underlies much recent philosophy of mind: that our commonsense
understanding of people rests on a speculative theory, a “folk psychology” that
posits mental states, events, and processes as unobservables that explain
behavior. Some hold that the simulation theory undercuts the debate between
philosophers who consider folk psychology a respectable theory and those the
eliminative materialists who reject it. Unlike earlier writing on empathic
understanding and historical reenactment, discussions of the simulation theory
often appeal to empirical findings, particularly experimental results in
developmental psychology. They also theorize about the mechanism that would
accomplish simulation: presumably one that calls up computational resources
ordinarily used for engagement with the world, but runs them off-line, so that
their output is not “endorsed” or acted upon and their inputs are not limited
to those that would regulate one’s own behavior. Although simulation theorists
agree that the ascription of mental states to others relies chiefly on
simulation, they differ on the nature of selfascription. Some especially Robert
Gordon and simple supposition simulation theory 845 845 Jane Heal, who independently proposed
the theory give a non-introspectionist account, while others especially Goldman
lean toward a more traditional introspectionist account. The simulation theory
has affected developmental psychology as well as branches of philosophy outside
the philosophy of mind, especially aesthetics and philosophy of the social
sciences. Some philosophers believe it sheds light on traditional topics such
as the problem of other minds, referential opacity, broad and narrow content,
and the peculiarities of self-knowledge.
singular term, an
expression, such as ‘Zeus’, ‘the President’, or ‘my favorite chair’, that can
be the grammatical subject of what is semantically a subject-predicate
sentence. By contrast, a general term, such as ‘table’ or ‘swam’ is one that
can serve in predicative position. It is also often said that a singular term
is a word or phrase that could refer or ostensibly refer, on a given occasion
of use, only to a single object, whereas a general term is predicable of more
than one object. Singular terms are thus the expressions that replace, or are
replaced by, individual variables in applications of such quantifier rules as
universal instantiation and existential generalization or flank ‘%’ in identity
statements.
situation ethics, a kind
of anti-theoretical, caseby-case applied ethics in vogue largely in some
European and religious circles for
twenty years or so following World War II. It is characterized by the
insistence that each moral choice must be determined by one’s particular
context or situation i.e., by a
consideration of the outcomes that various possible courses of action might
have, given one’s situation. To that degree, situation ethics has affinities to
both act utilitarianism and traditional casuistry. But in contrast to
utilitarianism, situation ethics rejects the idea that there are universal or
even fixed moral principles beyond various indeterminate commitments or ideals
e.g., to Christian love or humanism. In contrast to traditional casuistry, it
rejects the effort to construct general guidelines from a case or to classify
the salient features of a case so that it can be used as a precedent. The
anti-theoretical stance of situation ethics is so thoroughgoing that writers
identified with the position have not carefully described its connections to
consequentialism, existentialism, intuitionism, personalism, pragmatism,
relativism, or any other developed philosophical view to which it appears to
have some affinity.
st. john’s: st. john’s keeps a record of all of H. P. Grice’s tutees. It
is fascinating that Strawson’s closest collaboration, as Plato with Socrates,
and Aristotle with Plato, was with his tutee Strawson – whom Grice calls a
‘pupil,’ finding ‘tutee’ too French to his taste. G. J. Warnock recalls that,
of all the venues that the play group held, their favourite one was the room
overlooking the garden at st. john’s. “It’s one of the best gardens in England,
you know. Very peripathetic.” In alphabetical order, some of his English
‘gentlemanly’ tutees include: London-born J. L. Ackrill, London-born David
Bostock, London-born A. G. N. Flew, Leeds-born T. C. Potts, London-born P. F.
Strawson. They were happy to have Grice as a tutorial fellow, since he, unlike
Mabbot, was English, and did not instill on the tutees a vernacular furrin to
the area.
Skolem, Thoralf 73,
Norwegian mathematician. A pioneer of mathematical logic, he made fundamental
contributions to recursion theory, set theory in particular, the proposal and
formulation in 2 of the axiom of replacement, and model theory. His most
important results for the philosophy of mathematics are the Downward
Löwenheim-Skolem theorem 9, 2, whose first proof involved putting formulas into
Skolem normal form; and a demonstration 334 of the existence of models of
first-order arithmetic not isomorphic to the standard model. Both results
exhibit the extreme non-categoricity that can occur with formulations of
mathematical theories in firstorder logic, and caused Skolem to be skeptical
about the use of formal systems, particularly for set theory, as a foundation
for mathematics. The existence of non-standard models is actually a consequence
of the completeness and first incompleteness theorems Gödel, 0, 1, for these
together show that there must be sentences of arithmetic if consistent that are
true in the standard model, but false in some other, nonisomorphic model.
However, Skolem’s result describes a general technique for constructing such
models. Skolem’s theorem is now more easily proved using the compactness
theorem, an easy consequence of the completeness theorem. The Löwenheim-Skolem
theorem produces a similar problem of characterization, the Skolem paradox,
pointed out by Skolem in 2. Roughly, this says that if first-order set theory
has a model, it must also have a countable model whose continuum is a countable
set, and thus apparently non-standard. This does not contradict Cantor’s
theorem, which merely demands that the countable model contain as an element no
function that maps its natural numbers one-toone onto its continuum, although
there must be such a function outside the model. Although usually seen as
limiting first-order logic, this result is extremely fruitful technically,
providing one basis of the proof of the independence of the continuum
hypothesis from the usual axioms of set theory given by Gödel in 8 and Cohen in
3. This connection between independence results and the existence of countable
models was partially foreseen by Skolem in 2.
slippery slope argument,
an argument that an action apparently unobjectionable in itself would set in
motion a train of events leading ultimately to an undesirable outcome. The
metaphor portrays one on the edge of a slippery slope, where taking the first
step down will inevitably cause sliding to the bottom. For example, it is
sometimes argued that voluntary euthanasia should not be legalized because this
will lead to killing unwanted people, e.g. the handicapped or elderly, against
their will. In some versions the argument aims to show that one should
intervene to stop an ongoing train of events; e.g., it has been argued that
suppressing a Communist revolution in one country was necessary to prevent the
spread of Communism throughout a whole region via the so-called domino effect.
Slippery slope arguments with dubious causal assumptions are often classed as
fallacies under the general heading of the fallacy of the false cause. This
argument is also sometimes called the wedge argument. There is some
disagreement concerning the breadth of the category of slippery slope
arguments. Some would restrict the term to arguments with evaluative
conclusions, while others construe it more broadly so as to include other
sorites arguments.
Smart, John Jamieson
Carswell b.0, British-born Australian philosopher whose name is associated with
three doctrines in particular: the mindbody identity theory, scientific
realism, and utilitarianism. A student of Ryle’s at Oxford, he rejected logical
behaviorism in favor of what came to be known as Australian materialism. This
is the view that mental processes and,
as Armstrong brought Smart to see, mental states cannot be explained simply in terms of
behavioristic dispositions. In order to make good sense of how the ordinary
person talks of them we have to see them as brain processes and states
under other names. Smart developed this identity theory of mind and
brain, under the stimulus of his colleague, U. T. Place, in “Sensations and
Brain Processes” Philosophical Review, 9. It became a mainstay of
twentieth-century philosophy. Smart endorsed the materialist analysis of mind
on the grounds that it gave a simple picture that was consistent with the
findings of science. He took a realist view of the claims of science, rejecting
phenomenalism, instrumentalism, and the like, and he argued that commonsense
beliefs should be maintained only so far as they are plausible in the light of
total science. Philosophy and Scientific Realism 3 gave forceful expression to
this physicalist picture of the world, as did some later works. He attracted
attention in particular for his argument that if we take science seriously then
we have to endorse the four-dimensional picture of the universe and recognize
as an illusion the experience of the passing of time. He published a number of
defenses of utilitarianism, the best known being his contribution to J. J. C.
Smart and Bernard Williams, Utilitarianism, For and Against 3. He gave new life
to act utilitarianism at a time when utilitarians were few and most were
attached to rule utilitarianism or other restricted forms of the doctrine.
Smith, Adam 172390,
Scottish economist and philosopher, a founder of modern political economy and a
major contributor to ethics and the psychology of morals. His first published
work was The Theory of Moral Sentiments 1759. This book immediately made him
famous, and earned the praise of thinkers of the stature of Hume, Burke, and
Kant. It sought to answer two questions: Wherein does virtue consist, and by
means of what psychological principles do we determine this or that to be
virtuous or the contrary? His answer to the first combined ancient Stoic and
Aristotelian views of virtue with modern views derived from Hutcheson and
others. His answer to the second built on Hume’s theory of sympathy our ability to put ourselves imaginatively in
the situation of another as well as on
the notion of the “impartial spectator.” Smith throughout is skeptical about
metaphysical and theological views of virtue and of the psychology of morals.
The self-understanding of reasonable moral actors ought to serve as the moral
philosopher’s guide. Smith’s discussion ranges from the motivation of wealth to
the psychological causes of religious and political fanaticism. Smith’s second
published work, the immensely influential An Inquiry into the Nature and Causes
of the Wealth of Nations 1776, attempts to explain why free economic,
political, and religious markets are not only more efficient, when properly
regulated, but also more in keeping with nature, more likely to win the
approval of an impartial spectator, than monopolistic alternatives. Taken
together, Smith’s two books attempt to show how virtue and liberty can
complement each other. He shows full awareness of the potentially dehumanizing
force of what was later called “capitalism,” and sought remedies in schemes for
liberal education and properly organized religion. Smith did not live to
complete his system, which was to include an analysis of “natural
jurisprudence.” We possess student notes of his lectures on jurisprudence and
on rhetoric, as well as several impressive essays on the evolution of the
history of science and on the fine arts.
social action, a subclass
of human action involving the interaction among agents and their mutual
orientation, or the action of groups. While all intelligible actions are in
some sense social, social actions must be directed to others. Talcott Parsons
279 captured what is distinctive about social action in his concept of “double
contingency,” and similar concepts have been developed by other philosophers
and sociologists, including Weber, Mead, and Vitters. Whereas in monological
action the agents’ fulfilling their purposes depends only on contingent facts
about the world, the success of social action is also contingent on how other
agents react to what the agent does and how that agent reacts to other agents,
and so on. An agent successfully communicates, e.g., not merely by finding some
appropriate expression in an existing symbol system, but also by understanding
how other agents will understand him. Game theory describes and explains
another type of double contingency in its analysis of the interdependency of
choices and strategies among rational agents. Games are also significant in two
other respects. First, they exemplify the cognitive requirements for social
interaction, as in Mead’s analysis of agents’ perspective taking: as a subject
“I”, I am an object for others “me”, and can take a third-person perspective
along with others on the interaction itself “the generalized other”. Second,
games are regulated by shared rules and mediated through symbolic meanings;
Vitters’s private language argument establishes that rules cannot be followed
“privately.” Some philosophers, such as Peter Winch, conclude from this
argument that rule-following is a basic feature of distinctively social action.
Some actions are social in the sense that they can only be done in groups.
Individualists such as Weber, Jon Elster, and Raimo Tuomela believe that these
can be analyzed as the sum of the actions of each individual. But holists such
as Marx, Durkheim, and Margaret Gilbert reject this reduction and argue that in
social actions agents must see themselves as members of a collective agent.
Holism has stronger or weaker versions: strong holists, such as Durkheim and
Hegel, see the collective subject as singular, the collective consciousness of
a society. Weak holists, such as Gilbert and Habermas, believe that social
actions have plural, rather than singular, collective subjects. Holists
generally establish the plausibility of their view by referring to larger
contexts and sequences of action, such as shared symbol systems or social
institutions. Explanations of social actions thus refer not only to the mutual
expectations of agents, but also to these larger causal contexts, shared
meanings, and mechanisms of coordination. Theories of social action must then
explain the emergence of social order, and proposals range from Hobbes’s
coercive authority to Talcott Parsons’s value consensus about shared goals
among the members of groups. -- social
biology, the understanding of social behavior, especially human social
behavior, from a biological perspective; often connected with the political
philosophy of social Darwinism. Charles Darwin’s Origin of Species highlighted
the significance of social behavior in organic evolution, and in the Descent of
Man, he showed how significant such behavior is for humans. He argued that it
is a product of natural selection; but it was not until 4 that the English
biologist William Hamilton showed precisely how such behavior could evolve,
namely through “kin selection” as an aid to the biological wellbeing of close
relatives. Since then, other models of explanation have been proposed,
extending the theory to non-relatives. Best known is the self-describing
“reciprocal altruism.” Social biology became notorious in 5 when Edward O.
Wilson published a major treatise on the subject: Sociobiology: The New
Synthesis. Accusations of sexism and racism were leveled because Wilson
suggested that Western social systems are biologically innate, and that in some
respects males are stronger, more aggressive, more naturally promiscuous than
females. Critics argued that all social biology is in fact a manifestation of
social Darwinism, a nineteenthcentury philosophy owing more to Herbert Spencer
than to Charles Darwin, supposedly legitimating extreme laissez-faire economics
and an unbridled societal struggle for existence. Such a charge is extremely
serious, for as Moore pointed out in his Principia Ethica 3, Spencer surely
commits the naturalistic fallacy, inasmuch as he is attempting to derive the
way that the world ought to be from the way that it is. Naturally enough,
defenders of social biology, or “sociobiology” as it is now better known,
denied vehemently that their science is mere right-wing ideology by another
name. They pointed to many who have drawn very different social conclusions on
the basis of biology. Best known is the Russian anarchist Kropotkin, who argued
that societies are properly based on a biological propensity to mutual aid. With
respect to contemporary debate, it is perhaps fairest to say that sociobiology,
particularly that pertaining to humans, did not always show sufficient
sensitivity toward all societal groups
although certainly there was never the crude racism of the fascist
regimes of the 0s. However, recent work is far more careful in these respects.
Now, indeed, the study of social behavior from a biological perspective is one
of the most exciting and forward-moving branches of the life sciences. -- social choice theory, the theory of the
rational action of a group of agents. Important social choices are typically
made over alternative means of collectively providing goods. These might be
goods for individual members of the group, or more characteristically, public
goods, goods such that no one can be excluded from enjoying their benefits once
they are available. Perhaps the most central aspect of social choice theory
concerns rational individual choice in a social context. Since what is rational
for one agent to do will often depend on what is rational for another to do and
vice versa, these choices take on a strategic dimension. The prisoner’s dilemma
illustrates how it can be very difficult to reconcile individual and
collectively rational decisions, especially in non-dynamic contexts. There are
many situations, particularly in the provision of public goods, however, where
simple prisoner’s dilemmas can be avoided and more manageable coordination
problems remain. In these cases, individuals may find it rational to contractually
or conventionally bind themselves to courses of action that lead to the greater
good of all even though they are not straightforwardly utility-maximizing for
particular individuals. Establishing the rationality of these contracts or
conventions is one of the leading problems of social choice theory, because
coordination can collapse if a rational agent first agrees to cooperate and
then reneges and becomes a free rider on the collective efforts of others.
Other forms of uncooperative behaviors such as violating rules established by
society or being deceptive about one’s preferences pose similar difficulties.
Hobbes attempted to solve these problems by proposing that people would agree
to submit to the authority of a sovereign whose punitive powers would make
uncooperative behavior an unattractive option. It has also been argued that
cooperation is rational if the concept of rationality is extended beyond
utility-maximizing in the right way. Other arguments stress benefits beyond
selfinterest that accrue to cooperators. Another major aspect of social choice
theory concerns the rational action of a powerful central authority, or social
planner, whose mission is to optimize the social good. Although the central
planner may be instituted by rational individual choice, this part of the
theory simply assumes the institution. The planner’s task of making a onetime
allocation of resources to the production of various commodities is tractable
if social good or social utility is known as a function of various commodities.
When the planner must take into account dynamical considerations, the technical
problems are more difficult. This economic growth theory raises important
ethical questions about intergenerational conflict. The assumption of a social
analogue of the individual utility functions is particularly worrisome. It can
be shown formally that taking the results of majority votes can lead to
intransitive social orderings of possible choices and it is, therefore, a
generally unsuitable procedure for the planner to follow. Moreover, under very
general conditions there is no way of aggregating individual preferences into a
consistent social choice function of the kind needed by the planner. -- social constructivism, also called social
constructionism, any of a variety of views which claim that knowledge in some
area is the product of our social practices and institutions, or of the
interactions and negotiations between relevant social groups. Mild versions
hold that social factors shape interpretations of the world. Stronger versions
maintain that the world, or some significant portion of it, is somehow
constituted by theories, practices, and institutions. Defenders often move from
mild to stronger versions by insisting that the world is accessible to us only
through our interpretations, and that the idea of an independent reality is at
best an irrelevant abstraction and at worst incoherent. This philosophical
position is distinct from, though distantly related to, a view of the same name
in social and developmental psychology, associated with such figures as Piaget
and Lev Vygotsky, which sees learning as a process in which subjects actively
construct knowledge. Social constructivism has roots in Kant’s idealism, which
claims that we cannot know things in themselves and that knowledge of the world
is possible only by imposing pre-given categories of thought on otherwise
inchoate experience. But where Kant believed that the categories with which we
interpret and thus construct the world are given a priori, contemporary
constructivists believe that the relevant concepts and associated practices
vary from one group or historical period to another. Since there are no
independent standards for evaluating conceptual schemes, social constructivism
leads naturally to relativism. These views are generally thought to be present
in Kuhn’s The Structure of Scientific Revolutions, which argues that
observation and methods in science are deeply theory-dependent and that
scientists with fundamentally different assumptions or paradigms effectively
live in different worlds. Kuhn thus offers a view of science in opposition to
both scientific realism which holds that theory-dependent methods can give us
knowledge of a theory-independent world and empiricism which draws a sharp line
between theory and observation. Kuhn was reluctant to accept the apparently
radical consequences of his views, but his work has influenced recent social
studies of science, whose proponents frequently embrace both relativism and
strong constructivism. Another influence is the principle of symmetry advocated
by David Bloor and Barry Barnes, which holds that sociologists should explain
the acceptance of scientific views in the same way whether they believe those
views to be true or to be false. This approach is elaborated in the work of
Harry Collins, Steve Woolgar, and others. Constructivist themes are also
prominent in the work of feminist critics of science such as Sandra Harding and
Donna Haraway, and in the complex views of Bruno Latour. Critics, such as Richard
Boyd and Philip Kitcher, while applauding the detailed case studies produced by
constructivists, claim that the positive arguments for constructivism are
fallacious, that it fails to account satisfactorily for actual scientific
practice, and that like other versions of idealism and relativism it is only
dubiously coherent. -- social contract,
an agreement either between the people and their ruler, or among the people in
a community. The idea of a social contract has been used in arguments that
differ in what they aim to justify or explain e.g., the state, conceptions of
justice, morality, what they take the problem of justification to be, and
whether or not they presuppose a moral theory or purport to be a moral theory.
Traditionally the term has been used in arguments that attempt to explain the
nature of political obligation and/or the kind of responsibility that rulers
have to their subjects. Philosophers such as Plato, Hobbes, Locke, Rousseau,
and Kant argue that human beings would find life in a prepolitical “state of
nature” a state that some argue is also presocietal so difficult that they
would agree either with one another or
with a prospective ruler to the creation
of political institutions that each believes would improve his or her lot. Note
that because the argument explains political or social cohesion as the product
of an agreement among individuals, it makes these individuals conceptually
prior to political or social units. Marx and other socialist and communitarian
thinkers have argued against conceptualizing an individual’s relationship to
her political and social community in this way. Have social contracts in
political societies actually taken place? Hume ridicules the idea that they are
real, and questions what value makebelieve agreements can have as explanations
of actual political obligations. Although many social contract theorists admit
that there is almost never an explicit act of agreement in a community,
nonetheless they maintain that such an agreement is implicitly made when members
of the society engage in certain acts through which they give their tacit
consent to the ruling regime. It is controversial what actions constitute
giving tacit consent: Plato and Locke maintain that the acceptance of benefits
is sufficient to give such consent, but some have argued that it is wrong to
feel obliged to those who foist upon us benefits for which we have not asked.
It is also unclear how much of an obligation a person can be under if he gives
only tacit consent to a regime. How are we to understand the terms of a social
contract establishing a state? When the people agree to obey the ruler, do they
surrender their own power to him, as Hobbes tried to argue? Or do they merely
lend him that power, reserving the right to take it from him if and when they
see fit, as Locke maintained? If power is merely on loan to the ruler,
rebellion against him could be condoned if he violates the conditions of that
loan. But if the people’s grant of power is a surrender, there are no such
conditions, and the people could never be justified in taking back that power
via revolution. Despite controversies surrounding their interpretation, social
contract arguments have been important to the development of modern democratic
states: the idea of the government as the creation of the people, which they
can and should judge and which they have the right to overthrow if they find it
wanting, contributed to the development of democratic forms of polity in the
eighteenth and nineteenth centuries.
and revolutionaries explicitly
acknowledged their debts to social contract theorists such as Locke and
Rousseau. In the twentieth century, the social contract idea has been used as a
device for defining various moral conceptions e.g. theories of justice by those
who find its focus on individuals useful in the development of theories that
argue against views e.g. utilitarianism that allow individuals to be sacrificed
for the benefit of the group -- social epistemology, the study of the social
dimensions or determinants of knowledge, or the ways in which social factors
promote or perturb the quest for knowledge. Some writers use the term
‘knowledge’ loosely, as designating mere belief. On their view social
epistemology should simply describe how social factors influence beliefs, without
concern for the rationality or truth of these beliefs. Many historians and
sociologists of science, e.g., study scientific practices in the same spirit
that anthropologists study native cultures, remaining neutral about the
referential status of scientists’ constructs or the truth-values of their
beliefs. Others try to show that social factors like political or professional
interests are causally operative, and take such findings to debunk any
objectivist pretensions of science. Still other writers retain a normative,
critical dimension in social epistemology, but do not presume that social
practices necessarily undermine objectivity. Even if knowledge is construed as
true or rational belief, social practices might enhance knowledge acquisition.
One social practice is trusting the opinions of authorities, a practice that
can produce truth if the trusted authorities are genuinely authoritative. Such
trust may also be perfectly rational in a complex world, where division of
epistemic labor is required. Even a scientist’s pursuit of extra-epistemic
interests such as professional rewards may not be antithetical to truth in
favorable circumstances. Institutional provisions, e.g., judicial rules of
evidence, provide another example of social factors. Exclusionary rules might
actually serve the cause of truth or accuracy in judgment if the excluded
evidence would tend to mislead or prejudice jurors. -- social philosophy, broadly the philosophy
of socisocial Darwinism social philosophy 856
856 ety, including the philosophy of social science and many of its
components, e.g., economics and history, political philosophy, most of what we
now think of as ethics, and philosophy of law. But we may distinguish two
narrower senses. In one, it is the conceptual theory of society, including the
theory of the study of society the
common part of all the philosophical studies mentioned. In the other, it is a
normative study, the part of moral philosophy that concerns social action and
individual involvement with society in general. The central job of social
philosophy in the first of these narrower senses is to articulate the correct
notion or concept of society. This would include formulating a suitable
definition of ‘society’; the question is then which concepts are better for
which purposes, and how they are related. Thus we may distinguish “thin” and
“thick” conceptions of society. The former would identify the least that can be
said before we cease talking about society at all say, a number of people who interact, whose
actions affect the behavior of their fellows. Thicker conceptions would then
add such things as community rules, goals, customs, and ideals. An important
empirical question is whether any interacting groups ever do lack such things
and what if anything is common to the rules, etc., that actual societies have.
Descriptive social philosophy will obviously border on, if not merge into,
social science itself, e.g. into sociology, social psychology, or economics.
And some outlooks in social philosophy will tend to ally with one social
science as more distinctively typical than others e.g., the individualist view looks to
economics, the holist to sociology. A major methodological controversy concerns
holism versus individualism. Holism maintains that at least some social groups
must be studied as units, irreducible to their members: we cannot understand a
society merely by understanding the actions and motivations of its members.
Individualism denies that societies are “organisms,” and holds that we can
understand society only in that way. Classic G. sociologists e.g., Weber
distinguished between Gesellschaft, whose paradigm is the voluntary
association, such as a chess club, whose activities are the coordinated actions
of a number of people who intentionally join that group in order to pursue the
purposes that identify it; and Gemeinschaft, whose members find their
identities in that group. Thus, the are
not a group whose members teamed up with like-minded people to form society. They were before they had separate individual purposes.
The holist views society as essentially a Gemeinschaft. Individualists agree
that there are such groupings but deny that they require a separate kind of
irreducibly collective explanation: to understand the we must understand how typical individuals behave compared, say, with the G.s, and so on. The
methods of Western economics typify the analytical tendencies of methodological
individualism, showing how we can understand large-scale economic phenomena in
terms of the rational actions of particular economic agents. Cf. Adam Smith’s
invisible hand thesis: each economic agent seeks only his own good, yet the
result is the macrophenomenal good of the whole. Another pervasive issue
concerns the role of intentional characterizations and explanations in these
fields. Ordinary people explain behavior by reference to its purposes, and they
formulate these in terms that rely on public rules of language and doubtless
many other rules. To understand society, we must hook onto the selfunderstanding
of the people in that society this view is termed Verstehen. Recent work in
philosophy of science raises the question whether intentional concepts can
really be fundamental in explaining anything, and whether we must ultimately
conceive people as in some sense material systems, e.g. as computer-like. Major
questions for the program of replicating human intelligence in data-processing
terms cf. artificial intelligence are raised by the symbolic aspects of
interaction. Additionally, we should note the emergence of sociobiology as a
potent source of explanations of social phenomena. Normative social philosophy,
in turn, tends inevitably to merge into either politics or ethics, especially
the part of ethics dealing with how people ought to treat others, especially in
large groups, in relation to social institutions or social structures. This
contrasts with ethics in the sense concerned with how individual people may
attain the good life for themselves. All such theories allot major importance
to social relations; but if one’s theory leaves the individual wide freedom of
choice, then a theory of individually chosen goods will still have a
distinctive subject matter. The normative involvements of social philosophy
have paralleled the foregoing in important ways. Individualists have held that
the good of a society must be analyzed in terms of the goods of its individual
members. Of special importance has been the view that society must respect
indisocial philosophy social philosophy 857
857 vidual rights, blocking certain actions alleged to promote social
good as a whole. Organicist philosophers such as Hegel hold that it is the
other way around: the state or nation is higher than the individual, who is
rightly subordinated to it, and individuals have fundamental duties toward the
groups of which they are members. Outrightly fascist versions of such views are
unpopular today, but more benign versions continue in modified form, notably by
communitarians. Socialism and especially communism, though focused originally
on economic aspects of society, have characteristically been identified with
the organicist outlook. Their extreme opposite is to be found in the
libertarians, who hold that the right to individual liberty is fundamental in
society, and that no institutions may override that right. Libertarians hold
that society ought to be treated strictly as an association, a Gesellschaft,
even though they might not deny that it is ontogenetically Gemeinschaft. They
might agree that religious groups, e.g., cannot be wholly understood as
separate individuals. Nevertheless, the libertarian holds that religious and
cultural practices may not be interfered with or even supported by society.
Libertarians are strong supporters of free-market economic methods, and
opponents of any sort of state intervention into the affairs of individuals.
Social Darwinism, advocating the “survival of the socially fittest,” has
sometimes been associated with the libertarian view. Insofar as there is any
kind of standard view on these matters, it combines elements of both
individualism and holism. Typical social philosophers today accept that society
has duties, not voluntary for individual members, to support education, health,
and some degree of welfare for all. But they also agree that individual rights
are to be respected, especially civil rights, such as freedom of speech and
religion. How to combine these two apparently disparate sets of ideas into a
coherent whole is the problem. John Rawls’s celebrated Theory of Justice, 1, is
a contemporary classic that attempts to do just that.
Socinianism, an
unorthodox Christian religious movement originating in the sixteenth century
from the work of reformer Laelius
Socinus “Sozzini” in ; 152562 and his nephew Faustus Socinus 15391603. Born in
Siena of a patrician family, Laelius was widely read in theology. Influenced by
the evangelical movement in Italy, he made contact with noted Protestant
reformers, including Calvin and Melanchthon, some of whom questioned his
orthodoxy. In response, he wrote a confession of faith one of a small number of
his writings to have survived. After Laelius’s death, his work was carried on
by his nephew, Faustus, whose writings including On the Authority of Scripture,
1570; On the Savior Jesus Christ, 1578; and On Predestination, 1578 expressed
heterodox views. Faustus believed that Christ’s nature was entirely human, that
souls did not possess immortality by nature though there would be selective
resurrection for believers, that invocation of Christ in prayer was permissible
but not required, and he argued against predestination. After publication of
his 1578 writings, Faustus was invited to Transylvania and Poland to engage in
a dispute within the Reformed churches there. He decided to make his permanent
residence in Poland, which, through his tireless efforts, became the center of
the Socinian movement. The most important document of this movement was the
Racovian Catechism, published in 1605 shortly after Faustus’s death. The Minor
church of Poland, centered at Racov, became the focal point of the movement.
Its academy attracted hundreds of students and its publishing house produced
books in many languages defending Socinian ideas. Socinianism, as represented
by the Racovian Catechism and other writings collected by Faustus’s Polish
disciples, involves the views of Laelius and especially Faustus Socinus,
aligned with the anti-Trinitarian views of the Polish Minor church founded in
1556. It accepts Christ’s message as the definitive revelation of God, but
regards Christ as human, not divine; rejects the natural immortality of the
soul, but argues for the selective resurrection of the faithful; rejects the
doctrine of the Trinity; emphasizes human free will against predestinationism;
defends pacifism and the separation of church and state; and argues that
reason not creeds, dogmatic tradition,
or church authority must be the final
interpreter of Scripture. Its view of God is temporalistic: God’s eternity is
existence at all times, not timelessness, and God knows future free actions
only when they occur. In these respects, the Socinian view of God anticipates
aspects of modern process theology. Socinianism was suppressed in Poland in
1658, but it had already spread to other European social sciences, philosophy
of the Socinianism 858 858 countries,
including Holland where it appealed to followers of Arminius and England, where
it influenced the Cambridge Platonists, Locke, and other philosophers, as well
as scientists like Newton. In England, it also influenced and was closely
associated with the development of Unitarianism.
Socrates 469399 B.C.,
Grecian philosopher, the exemplar of the examined life, best known for his
dictum that only such a life is worth living. Although he wrote nothing, his
thoughts and way of life had a profound impact on many of his contemporaries,
and, through Plato’s portrayal of him in his early writings, he became a major
source of inspiration and ideas for later generations of philosophers. His
daily occupation was adversarial public conversation with anyone willing to
argue with him. A man of great intellectual brilliance, moral integrity,
personal magnetism, and physical self-command, he challenged the moral
complacency of his fellow citizens, and embarrassed them with their inability
to answer such questions as What is virtue?
questions that he thought we must answer, if we are to know how best to
live our lives. His ideas and personality won him a devoted following among the
young, but he was far from universally admired. Formal charges were made
against him for refusing to recognize the gods of the city, introducing other
new divinities, and corrupting the youth. Tried on a single day before a large
jury 500 was a typical size, he was found guilty by a small margin: had thirty
jurors voted differently, he would have been acquitted. The punishment selected
by the jury was death and was administered by means of poison, probably
hemlock. Why was he brought to trial and convicted? Part of the answer lies in
Plato’s Apology, which purports to be the defense Socrates gave at his trial.
Here he says that he has for many years been falsely portrayed as someone whose
scientific theories dethrone the traditional gods and put natural forces in
their place, and as someone who charges a fee for offering private instruction
on how to make a weak argument seem strong in the courtroom. This is the
picture of Socrates drawn in a play of Aristophanes, the Clouds, first
presented in 423. It is unlikely that Aristophanes intended his play as an
accurate depiction of Socrates, and the unscrupulous buffoon found in the
Clouds would never have won the devotion of so serious a moralist as Plato.
Aristophanes drew together the assorted characteristics of various
fifth-century thinkers and named this amalgam “Socrates” because the real
Socrates was one of several controversial intellectuals of the period.
Nonetheless, it is unlikely that the charges against Socrates or Aristophanes’
caricature were entirely without foundation. Both Xenophon’s Memorabilia and
Plato’s Euthyphro say that Socrates aroused suspicion because he thought a
certain divine sign or voice appeared to him and gave him useful instruction
about how to act. By claiming a unique and private source of divine
inspiration, Socrates may have been thought to challenge the city’s exclusive
control over religious matters. His willingness to disobey the city is admitted
in Plato’s Apology, where he says that he would have to disobey a hypothetical
order to stop asking his philosophical questions, since he regards them as
serving a religious purpose. In the Euthyphro he seeks a rational basis for
making sacrifices and performing other services to the gods; but he finds none,
and implies that no one else has one. Such a challenge to traditional religious
practice could easily have aroused a suspicion of atheism and lent credibility
to the formal charges against him. Furthermore, Socrates makes statements in
Plato’s early dialogues and in Xenophon’s Memorabilia that could easily have
offended the political sensibilities of his contemporaries. He holds that only
those who have given special study to political matters should make decisions.
For politics is a kind of craft, and in all other crafts only those who have
shown their mastery are entrusted with public responsibilities. Athens was a
democracy in which each citizen had an equal legal right to shape policy, and
Socrates’ analogy between the role of an expert in politics and in other crafts
may have been seen as a threat to this egalitarianism. Doubts about his political
allegiance, though not mentioned in the formal charges against him, could
easily have swayed some jurors to vote against him. Socrates is the subject not
only of Plato’s early dialogues but also of Xenophon’s Memorabilia, Socinus,
Faustus Socrates 859 859 and in many
respects their portraits are consistent with each other. But there are also
some important differences. In the Memorabilia, Socrates teaches whatever a
gentleman needs to know for civic purposes. He is filled with platitudinous
advice, and is never perplexed by the questions he raises; e.g., he knows what
the virtues are, equating them with obedience to the law. His views are not
threatening or controversial, and always receive the assent of his
interlocutors. By contrast, Plato’s Socrates presents himself as a perplexed
inquirer who knows only that he knows nothing about moral matters. His
interlocutors are sometimes annoyed by his questions and threatened by their
inability to answer them. And he is sometimes led by force of argument to controversial
conclusions. Such a Socrates could easily have made enemies, whereas Xenophon’s
Socrates is sometimes too “good” to be true. But it is important to bear in
mind that it is only the early works of Plato that should be read as an
accurate depiction of the historical Socrates. Plato’s own theories, as
presented in his middle and late dialogues, enter into philosophical terrain
that had not been explored by the historical Socrates even though in the middle and some of the
late dialogues a figure called Socrates remains the principal speaker. We are
told by Aristotle that Socrates confined himself to ethical questions, and that
he did not postulate a separate realm of imperceptible and eternal abstract
objects called “Forms” or “Ideas.” Although the figure called Socrates affirms
the existence of these objects in such Platonic dialogues as the Phaedo and the
Republic, Aristotle takes this interlocutor to be a vehicle for Platonic
philosophy, and attributes to Socrates only those positions that we find in
Plato’s earlier writing, e.g. in the Apology, Charmides, Crito, Euthyphro,
Hippias Minor, Hippias Major, Ion, Laches, Lysis, and Protagoras. Socrates
focused on moral philosophy almost exclusively; Plato’s attention was also
devoted to the study of metaphysics, epistemology, physical theory,
mathematics, language, and political philosophy. When we distinguish the
philosophies of Socrates and Plato in this way, we find continuities in their
thought for instance, the questions
posed in the early dialogues receive answers in the Republic but there are important differences. For
Socrates, being virtuous is a purely intellectual matter: it simply involves
knowing what is good for human beings; once we master this subject, we will act
as we should. Because he equates virtue with knowledge, Socrates frequently
draws analogies between being virtuous and having mastered any ordinary
subject cooking, building, or geometry,
e.g. For mastery of these subjects does not involve a training of the emotions.
By contrast, Plato affirms the existence of powerful emotional drives that can
deflect us from our own good, if they are not disciplined by reason. He denies
Socrates’ assumption that the emotions will not resist reason, once one comes
to understand where one’s own good lies. Socrates says in Plato’s Apology that
the only knowledge he has is that he knows nothing, but it would be a mistake
to infer that he has no convictions about moral matters convictions arrived at through a difficult
process of reasoning. He holds that the unexamined life is not worth living,
that it is better to be treated unjustly than to do injustice, that
understanding of moral matters is the only unconditional good, that the virtues
are all forms of knowledge and cannot be separated from each other, that death
is not an evil, that a good person cannot be harmed, that the gods possess the
wisdom human beings lack and never act immorally, and so on. He does not accept
these propositions as articles of faith, but is prepared to defend any of them;
for he can show his interlocutors that their beliefs ought to lead them to
accept these conclusions, paradoxical though they may be. Since Socrates can
defend his beliefs and has subjected them to intellectual scrutiny, why does he
present himself as someone who has no knowledge
excepting the knowledge of his own ignorance? The answer lies in his
assumption that it is only a fully accomplished expert in any field who can
claim knowledge or wisdom of that field; someone has knowledge of navigational
matters, e.g., only if he has mastered the art of sailing, can answer all
inquiries about this subject, and can train others to do the same. Judged by
this high epistemic standard, Socrates can hardly claim to be a moral expert,
for he lacks answers to the questions he raises, and cannot teach others to be
virtuous. Though he has examined his moral beliefs and can offer reasons for
them an accomplishment that gives him an
overbearing sense of superiority to his contemporaries he takes himself to be quite distant from the
ideal of moral perfection, which would involve a thorough understanding of all
moral matters. This keen sense of the moral and intellectual deficiency of all
human beings accounts for a great deal of Socrates’ appeal, just as his
arrogant disdain for his fellow citizens no doubt contributed to his demise.
Socrates Socrates 860 860 -- Socratic intellectualism, the claim that
moral goodness or virtue consists exclusively in a kind of knowledge, with the
implication that if one knows what is good and evil, one cannot fail to be a
good person and to act in a morally upright way. The claim and the term derive
from Socrates; a corollary is another claim of Socrates: there is no moral
weakness or akrasia all wrong action is
due to the agent’s ignorance. Socrates defends this view in Plato’s dialogue
Protagoras. There are two ways to understand Socrates’ view that knowledge of
the good is sufficient for right action. 1 All desires are rational, being
focused on what is believed to be good; thus, an agent who knows what is good
will have no desire to act contrary to that knowledge. 2 There are non-rational
desires, but knowledge of the good has sufficient motivational power to
overcome them. Socratic intellectualism was abandoned by Plato and Aristotle, both
of whom held that emotional makeup is an essential part of moral character.
However, they retained the Socratic idea that there is a kind of knowledge or
wisdom that ensures right action but
this knowledge presupposes antecedent training and molding of the passions.
Socratic intellectualism was later revived and enjoyed a long life as a key
doctrine of the Stoics. -- Socratic
irony, a form of indirect communication frequently employed by Socrates in
Plato’s early dialogues, chiefly to praise insincerely the abilities of his
interlocutors while revealing their ignorance; or, to disparage his own
abilities, e.g. by denying that he has knowledge. Interpreters disagree whether
Socrates’ self-disparagement is insincere.
-- Socratic paradoxes, a collection of theses associated with Socrates
that contradict opinions about moral or practical matters shared by most
people. Although there is no consensus on the precise number of Socratic
paradoxes, each of the following theses has been identified as one. 1 Because
no one desires evil things, anyone who pursues evil things does so
involuntarily. 2 Because virtue is knowledge, anyone who does something morally
wrong does so involuntarily. 3 It is better to be unjustly treated than to do
what is unjust. The first two theses are associated with weakness of will or
akrasia. It is sometimes claimed that the topic of the first thesis is
prudential weakness, whereas that of the second is moral weakness; the
reference to “evil things” in 1 is not limited to things that are morally evil.
Naturally, various competing interpretations of these theses have been
offered.
solipsism, the doctrine
that there exists a firstperson perspective possessing privileged and
irreducible characteristics, in virtue of which we stand in various kinds of
isolation from any other persons or external things that may exist. This
doctrine is associated with but distinct from egocentricism. On one variant of
solipsism Thomas Nagel’s we are isolated from other sentient beings because we
can never adequately understand their experience empathic solipsism. Another
variant depends on the thesis that the meanings or referents of all words are
mental entities uniquely accessible only to the language user semantic
solipsism. A restricted variant, due to Vitters, asserts that first-person
ascriptions of psychological states have a meaning fundamentally different from
that of second- or thirdperson ascriptions psychological solipsism. In extreme
forms semantic solipsism can lead to the view that the only things that can be
meaningfully said to exist are ourselves or our mental states ontological
solipsism. Skepticism about the existence of the world external to our minds is
sometimes considered a form of epistemological solipsism, since it asserts that
we stand in epistemological isolation from that world, partly as a result of
the epistemic priority possessed by firstperson access to mental states. In
addition to these substantive versions of solipsism, several variants go under
the rubric methodological solipsism. The idea is that when we seek to explain
why sentient beings behave in certain ways by looking to what they believe,
desire, hope, and fear, we should identify these psychological states only with
events that occur inside the mind or brain, not with external events, since the
former alone are the proximate and sufficient causal explanations of bodily
behavior. Socratic intellectualism solipsism 861 861
Solovyov, Vladimir 18530,
Russian philosopher, theologian, essayist, and poet. In addition to major
treatises and dialogues in speculative philosophy, Solovyov wrote sensitive
literary criticism and influential essays on current social, political, and
ecclesiastical questions. His serious verse is subtle and delicate; his light
verse is rich in comic invention. The mystical image of the “Divine Sophia,”
which Solovyov articulated in theoretical concepts as well as poetic symbols,
powerfully influenced the Russian symbolist poets of the early twentieth
century. His stress on the human role in the “divine-human process” that
creates both cosmic and historical being led to charges of heresy from Russian
Orthodox traditionalists. Solovyov’s rationalistic “justification of the good”
in history, society, and individual life was inspired by Plato, Spinoza, and
especially Hegel. However, at the end of his life Solovyov offered in Three
Conversations on War, Progress, and the End of History, 0 a contrasting
apocalyptic vision of historical and cosmic disaster, including the appearance,
in the twenty-first century, of the Antichrist. In ethics, social philosophy,
philosophy of history, and theory of culture, Solovyov was both a vigorous
ecumenist and a “good European” who affirmed the intrinsic value of both the
“individual human person” Russian lichnost’ and the “individual nation or
people” narodnost’, but he decisively repudiated the perversions of these
values in egoism and nationalism, respectively. He contrasted the fruits of
English narodnost’ the works of Shakespeare
and Byron, Berkeley and Newton with the
fruits of English nationalism the
repressive and destructive expansion of the British Empire. In opposing ethnic,
national, and religious exclusiveness and self-centeredness, Solovyov also, and
quite consistently, opposed the growing xenophobia and antiSemitism of his own
time. Since 8 long-suppressed works by and about Solovyov have been widely
republished in Russia, and fresh interpretations of his philosophy and theology
have begun to appear.
sophisma, a sentenca
illustrating a semantic or logical issue associated with the analysis of a
syncategorematic term, or a term lacking independent signification. Typically a
sophisma was used from the thirteenth century into the sixteenth century to
analyze relations holding between logic or semantics and broader philosophical
issues. For example, the syncategorematic term ‘besides’ praeter in ‘Socrates
twice sees every man besides Plato’ is ambiguous, because it could mean ‘On two
occasions Socrates sees every-man-but-Plato’ and also ‘Except for overlooking
Plato once, on two occasions Socrates sees every man’. Roger Bacon used this
sophisma to discuss the ambiguity of distribution, in this case, of the scope
of the reference of ‘twice’ and ‘besides’. Sherwood used the sophisma to
illustrate the applicability of his rule of the distribution of ambiguous
syncategoremata, while Pseudo-Peter of Spain uses it to establish the truth of
the rule, ‘If a proposition is in part false, it can be made true by means of
an exception, but not if it is completely false’. In each case, the philosopher
uses the ambiguous signification of the syncategorematic term to analyze
broader logical problems. The sophisma ‘Every man is of necessity an animal’
has ambiguity through the syncategorematic ‘every’ that leads to broader philosophical
problems. In the 1270s, Boethius of Dacia analyzed this sophisma in terms of
its applicability when no man exists. Is the knowledge derived from
understanding the proposition destroyed when the object known is destroyed?
Does ‘man’ signify anything when there are no men? If we can correctly
predicate a genus of a species, is the nature of the genus in that species
something other than, or distinct from, what finally differentiates the
species? In this case, the sophisma proves a useful approach to addressing
metaphysical and epistemological problems central to Scholastic discourse.
sophisma: any of a number
of ancient Grecians, roughly contemporaneous with Socrates, who professed to
teach, for a fee, rhetoric, philosophy, and how to succeed in life. They
typically were itinerants, visiting much of the Grecian world, and gave public
exhibitions at Olympia and Delphi. They were part of the general expansion of
Grecian learning and of the changing culture in which the previous informal
educational methods were inadequate. For example, the growing litigiousness of
Athenian society demanded Solovyov, Vladimir Sophists 862 862 instruction in the art of speaking well,
which the Sophists helped fulfill. The Sophists have been portrayed as
intellectual charlatans hence the pejorative use of ‘sophism’, teaching their
sophistical reasoning for money, and at the other extreme as Victorian
moralists and educators. The truth is more complex. They were not a school, and
shared no body of opinions. They were typically concerned with ethics unlike
many earlier philosophers, who emphasized physical inquiries and about the
relationship between laws and customs nomos and nature phusis. Protagoras of
Abdera c.490c.420 B.C. was the most famous and perhaps the first Sophist. He
visited Athens frequently, and became a friend of its leader, Pericles; he
therefore was invited to draw up a legal code for the colony of Thurii 444.
According to some late reports, he died in a shipwreck as he was leaving
Athens, having been tried for and found guilty of impiety. He claimed that he
knew nothing about the gods, because of human limitations and the difficulty of
the question. We have only a few short quotations from his works. His “Truth”
also known as the “Throws,” i.e., how to overthrow an opponent’s arguments
begins with his most famous claim: “Humans are the measure of all things of things that are, that they are, of things
that are not, that they are not.” That is, there is no objective truth; the
world is for each person as it appears to that person. Of what use, then, are
skills? Skilled people can change others’ perceptions in useful ways. For
example, a doctor can change a sick person’s perceptions so that she is
healthy. Protagoras taught his students to “make the weaker argument the
stronger,” i.e., to alter people’s perceptions about the value of arguments.
Aristophanes satirizes Protagoras as one who would make unjust arguments defeat
just arguments. This is true for ethical judgments, too: laws and customs are
simply products of human agreement. But because laws and customs result from
experiences of what is most useful, they should be followed rather than nature.
No perception or judgment is more true than another, but some are more useful,
and those that are more useful should be followed. Gorgias c.483376 was a
student of Empedocles. His town, Leontini in Sicily, sent him as an ambassador
to Athens in 427; his visit was a great success, and the Athenians were amazed
at his rhetorical ability. Like other Sophists, he charged for instruction and
gave speeches at religious festivals. Gorgias denied that he taught virtue;
instead, he produced clever speakers. He insisted that different people have
different virtues: for example, women’s virtue differs from men’s. Since there
is no truth and if there were we couldn’t know it, we must rely on opinion, and
so speakers who can change people’s opinions have great power greater than the power produced by any other
skill. In his “Encomium on Helen” he argues that if she left Menelaus and went
with Paris because she was convinced by speech, she wasn’t responsible for her
actions. Two paraphrases of Gorgias’s “About What Doesn’t Exist” survive; in
this he argues that nothing exists, that even if something did, we couldn’t
know it, and that even if we could know anything we couldn’t explain it to
anyone. We can’t know anything, because some things we think of do not exist,
and so we have no way of judging whether the things we think of exist. And we
can’t express any knowledge we may have, because no two people can think of the
same thing, since the same thing can’t be in two places, and because we use
words in speech, not colors or shapes or objects. This may be merely a parody
of Parmenides’ argument that only one thing exists. Antiphon the Sophist fifth
century is probably although not certainly to be distinguished from Antiphon
the orator d. 411, some of whose speeches we possess. We know nothing about his
life if he is distinct from the orator. In addition to brief quotations in later
authors, we have two papyrus fragments of his “On Truth.” In these he argues
that we should follow laws and customs only if there are witnesses and so our
action will affect our reputation; otherwise, we should follow nature, which is
often inconsistent with following custom. Custom is established by human
agreement, and so disobeying it is detrimental only if others know it is
disobeyed, whereas nature’s demands unlike those of custom can’t be ignored
with impunity. Antiphon assumes that rational actions are selfinterested, and
that justice demands actions contrary to self-interest a position Plato attacks in the Republic.
Antiphon was also a materialist: the nature of a bed is wood, since if a buried
bed could grow it would grow wood, not a bed. His view is one of Aristotle’s
main concerns in the Physics, since Aristotle admits in the Categories that
persistence through change is the best test for substance, but won’t admit that
matter is substance. Hippias fifth century was from Elis, in the Peloponnesus,
which used him as an ambasSophists Sophists 863 863 sador. He competed at the festival of
Olympus with both prepared and extemporaneous speeches. He had a phenomenal
memory. Since Plato repeatedly makes fun of him in the two dialogues that bear
his name, he probably was selfimportant and serious. He was a polymath who
claimed he could do anything, including making speeches and clothes; he wrote a
work collecting what he regarded as the best things said by others. According
to one report, he made a mathematical discovery the quadratrix, the first curve
other than the circle known to the Grecians. In the Protagoras, Plato has
Hippias contrast nature and custom, which often does violence to nature.
Prodicus fifth century was from Ceos, in the Cyclades, which frequently
employed him on diplomatic missions. He apparently demanded high fees, but had
two versions of his lecture one cost
fifty drachmas, the other one drachma. Socrates jokes that if he could have
afforded the fifty-drachma lecture, he would have learned the truth about the
correctness of words, and Aristotle says that when Prodicus added something
exciting to keep his audience’s attention he called it “slipping in the
fifty-drachma lecture for them.” We have at least the content of one lecture of
his, the “Choice of Heracles,” which consists of banal moralizing. Prodicus was
praised by Socrates for his emphasis on the right use of words and on
distinguishing between synonyms. He also had a naturalistic view of the origin
of theology: useful things were regarded as gods.
Sorel: G. socialist
activist and philosopher best known for his Reflections on Violence 6, which
develops the notion of revolutionary syndicalism as seen through proletarian
violence and the interpretation of myth. An early proponent of the quasiMarxist
position of gradual democratic reformism, Sorel eventually developed a highly
subjective interpretation of historical materialism that, while retaining a
conception of proletarian revolution, now understood it through myth rather
than reason. He was in large part reacting to the empiricism of the Enlightenment and the statistical structuring
of sociological studies. In contrast to Marx and Engels, who held that
revolution would occur when the proletariat attained its own class consciousness
through an understanding of its true relationship to the means of production in
capitalist society, Sorel introduced myth rather than reason as the correct way
to interpret social totality. Myth allows for the necessary reaction to
bourgeois rationalism and permits the social theorist to negate the status quo
through the authenticity of revolutionary violence. By acknowledging the
irrationality of the status quo, myth permits the possibility of social
understanding and its necessary reaction, human emancipation through
proletarian revolution. Marxism is myth because it juxtaposes the
irreducibility of capitalist organization to its negation violent proletarian revolution. The
intermediary stage in this development is radical syndicalism, which organizes
workers into groups opposed to bourgeois authority, instills the myth of
proletarian revolution in the workers, and allows them in postrevolutionary
times to work toward a social arrangement of worker and peasant governance and
collaboration. The vehicle through which all this is accomplished is the
general strike, whose aim, through the justified violence of its ends, is to
facilitate the downfall and ultimate elimination of the bourgeoisie. In doing
so the proletariat will lead society to a classless and harmonious stage in
history. By stressing the notion of spontaneity Sorel thought he had solved the
vexing problems of party and future bureaucracy found in much of the
revolutionary literature of his day. In his later years he was interested in the
writings of both Lenin and Mussolini.
sorites, an argument
consisting of categorical propositions that can be represented as or decomposed
into a sequence of categorical syllogisms such that the conclusion of each
syllogism except the last one in the sequence is a premise of the next syllogism
in the sequence. An example is ‘All cats are felines; all felines are mammals;
all mammals are warm-blooded animals; therefore, all cats are warm-blooded
animals’. This sorites may be viewed as composed of the two syllogisms ‘All
cats are felines; all felines are mammals; therefore, all cats are mammals’ and
‘All cats are mammals; all mammals are warm-blooded animals; therefore, all
cats are warm-blooded animals’. A sorites is valid if and only if each
categorical syllogism into which it decomposes is valid. In the example, the
sorites decomposes into two syllogisms in the mood Barbara; since any syllogism
in Barbara is valid, the sorites is valid.
sorites paradox from
Grecian soros, ‘heap’, any of a number of paradoxes about heaps and their
Sorel, Georges sorites paradox 864 864
elements, and more broadly about gradations. A single grain of sand cannot be
arranged so as to form a heap. Moreover, it seems that given a number of grains
insufficient to form a heap, adding just one more grain still does not make a
heap. If a heap cannot be formed with one grain, it cannot be formed with two;
if a heap cannot be formed with two, it cannot be formed with three; and so on.
But this seems to lead to the absurdity that however large the number of
grains, it is not large enough to form a heap. A similar paradox can be
developed in the opposite direction. A million grains of sand can certainly be
arranged so as to form a heap, and it is always possible to remove a grain from
a heap in such a way that what is left is also a heap. This seems to lead to
the absurdity that a heap can be formed even from just a single grain. These
paradoxes about heaps were known in antiquity they are associated with
Eubulides of Miletus, fourth century B.C., and have since given their name to a
number of similar paradoxes. The loss of a single hair does not make a man
bald, and a man with a million hairs is certainly not bald. This seems to lead
to the absurd conclusion that even a man with no hairs at all is not bald. Or
consider a long painted wall hundreds of yards or hundreds of miles long. The
left-hand region is clearly painted red, but there is a subtle gradation of
shades and the right-hand region is clearly yellow. A small double window
exposes a small section of the wall at any one time. It is moved progressively
rightward, in such a way that at each move after the initial position the
left-hand segment of the window exposes just the area that was in the previous
position exposed by the right-hand segment. The window is so small relative to
the wall that in no position can you tell any difference in color between the
exposed areas. When the window is at the extreme left, both exposed areas are
certainly red. But as the window moves to the right, the area in the right
segment looks just the same color as the area in the left, which you have
already pronounced to be red. So it seems that one must call it red too. But
then one is led to the absurdity of calling a clearly yellow area red. As some
of these cases suggest, there is a connection with dynamic processes. A tadpole
turns gradually into a frog. Yet if you analyze a motion picture of the
process, it seems that there are no two adjacent frames of which you can say
the earlier shows a tadpole, the later a frog. So it seems that you could
argue: if something is a tadpole at a given moment, it must also be a tadpole
and not a frog a millionth of a second later, and this seems to lead to the
absurd conclusion that a tadpole can never turn into a frog. Most responses to
this paradox attempt to deny the “major premise,” the one corresponding to the
claim that if you cannot make a heap with n grains of sand then you cannot make
a heap with n ! 1. The difficulty is that the negation of this premise is
equivalent, in classical logic, to the proposition that there is a sharp
cutoff: that, e.g., there is some number n of grains that are not enough to
make a heap, where n ! 1 are enough to make a heap. The claim of a sharp cutoff
may not be so very implausible for heaps perhaps for things like grains of
sand, four is the smallest number which can be formed into a heap but is very
implausible for colors and tadpoles. There are two main kinds of response to
sorites paradoxes. One is to accept that there is in every such case a sharp
cutoff, though typically we do not, and perhaps cannot, know where it is.
Another kind of response is to evolve a non-classical logic within which one
can refuse to accept the major premise without being committed to a sharp
cutoff. At present, no such non-classical logic is entirely free of
difficulties. So sorites paradoxes are still taken very seriously by
contemporary philosophers.
sortal predicate,
roughly, a predicate whose application to an object says what kind of object it
is and implies conditions for objects of that kind to be identical. Person,
green apple, regular hexagon, and pile of coal would generally be regarded as
sortal predicates, whereas tall, green thing, and coal would generally be
regarded as non-sortal predicates. An explicit and precise definition of the
distinction is hard to come by. Sortal predicates are sometimes said to be
distinguished by the fact that they provide a criterion of counting or that
they do not apply to the parts of the objects to which they apply, but there
are difficulties with each of these characterizations. The notion figures in
recent philosophical discussions on various topics. Robert Ackermann and others
have suggested that any scientific law confirmable by observation might require
the use of sortal predicates. Thus ‘all non-black things are non-ravens’, while
logically equivalent to the putative scientific law ‘all ravens are black’, is
not itself confirmable by observation because ‘non-black’ is not a sortal
predicate. David Wiggins and others have discussed the sortal sortal predicate
865 865 idea that all identity claims
are sortal-relative in the sense that an appropriate response to the claim a %
b is always “the same what as b?” John Wallace has argued that there would be
advantages in relativizing the quantifiers of predicate logic to sortals. ‘All
humans are mortal’ would be rendered Ex[m]Dx, rather than ExMxPDx. Crispin
Wright has suggested that the view that natural number is a sortal concept is
central to Frege’s or any other number-theoretic platonism. The word ‘sortal’
as a technical term in philosophy apparently first occurs in Locke’s Essay
Concerning Human Understanding. Locke argues that the so-called essence of a
genus or sort unlike the real essence of a thing is merely the abstract idea
that the general or sortal name stands for. But ‘sortal’ has only one
occurrence in Locke’s Essay. Its currency in contemporary philosophical idiom
probably should be credited to P. F. Strawson’s Individuals. The general idea
may be traced at least to the notion of second substance in Aristotle’s
Categories.
Soto, Domingo de
14941560, Dominican theologian and
philosopher. Born in Segovia, he studied in Alcalá de Henares and Paris, taught
at Segovia and Salamanca, and was named official representative of the Holy Roman
Empire at the Council of Trent by Charles V. Among Soto’s many works, his
commentaries on Aristotle’s Physics and On the Soul stand out. He also wrote a
book on the nature of grace and an important treatise on law. Soto was one of
the early members of the school of
Thomism, but he did not always follow Aquinas. He rejected the doctrine
of the real distinction between essence and existence and adopted Duns Scotus’s
position that the primary object of human understanding is indeterminate being
in general. Apart from metaphysics and theology, Soto’s philosophy of law and
political theory are historically important. He maintained, contrary to his
teacher Vitoria, that law originates in the understanding rather than in the
will of the legislator. He also distinguished natural from positive law: the
latter arises from the decision of legislators, whereas the former is based on
nature. Soto was a founder of the general theory of international law.
soul, -- cf. Grice on
“soul-to-soul transfer” -- also called spirit, an entity supposed to be present
only in living things, corresponding to the Grecian psyche and Latin anima.
Since there seems to be no material difference between an organism in the last
moments of its life and the organism’s newly dead body, many philosophers since
the time of Plato have claimed that the soul is an immaterial component of an
organism. Because only material things are observed to be subject to
dissolution, Plato took the soul’s immateriality as grounds for its
immortality. Neither Plato nor Aristotle thought that only persons had souls:
Aristotle ascribed souls to animals and plants since they all exhibited some
living functions. Unlike Plato, Aristotle denied the transmigration of souls
from one species to another or from one body to another after death; he was
also more skeptical about the soul’s capacity for disembodiment roughly, survival and functioning without a
body. Descartes argued that only persons had souls and that the soul’s immaterial
nature made freedom possible even if the human body is subject to deterministic
physical laws. As the subject of thought, memory, emotion, desire, and action,
the soul has been supposed to be an entity that makes self-consciousness
possible, that differentiates simultaneous experiences into experiences either
of the same person or of different persons, and that accounts for personal
identity or a person’s continued identity through time. Dualists argue that
soul and body must be distinct in order to explain consciousness and the
possibility of immortality. Materialists argue that consciousness is entirely
the result of complex physical processes.
soundness, 1 of an
argument the property of being valid and having all true premises; 2 of a logic
the property of being not too strong in a certain respect. A logic L has weak
soundness provided every theorem of L is valid. And L has strong soundness if
for every set G of sentences, every sentence deducible from G using L is a
logical consequence of G.
space, an extended
manifold of several dimensions, where the number of dimensions corresponds to
the number of variable magnitudes Soto, Domingo de space 866 866 needed to specify a location in the
manifold; in particular, the three-dimensional manifold in which physical
objects are situated and with respect to which their mutual positions and
distances are defined. Ancient Grecian atomism defined space as the infinite
void in which atoms move; but whether space is finite or infinite, and whether
void spaces exist, have remained in question. Aristotle described the universe
as a finite plenum and reduced space to the aggregate of all places of physical
things. His view was preeminent until Renaissance Neoplatonism, the Copernican
revolution, and the revival of atomism reintroduced infinite, homogeneous space
as a fundamental cosmological assumption. Further controversy concerned whether
the space assumed by early modern astronomy should be thought of as an
independently existing thing or as an abstraction from the spatial relations of
physical bodies. Interest in the relativity of motion encouraged the latter
view, but Newton pointed out that mechanics presupposes absolute distinctions
among motions, and he concluded that absolute space must be postulated along
with the basic laws of motion Principia, 1687. Leibniz argued for the
relational view from the identity of indiscernibles: the parts of space are
indistinguishable from one another and therefore cannot be independently
existing things. Relativistic physics has defused the original controversy by revealing
both space and spatial relations as merely observer-dependent manifestations of
the structure of spacetime. Meanwhile, Kant shifted the metaphysical
controversy to epistemological grounds by claiming that space, with its
Euclidean structure, is neither a “thing-in-itself” nor a relation of
thingsin-themselves, but the a priori form of outer intuition. His view was
challenged by the elaboration of non-Euclidean geometries in the nineteenth
century, by Helmholtz’s arguments that both intuitive and physical space are
known through empirical investigation, and finally by the use of non-Euclidean
geometry in the theory of relativity. Precisely what geometrical
presuppositions are inherent in human spatial perception, and what must be
learned from experience, remain subjects of psychological investigation.
space-time, a
four-dimensional continuum combining the three dimensions of space with time in
order to represent motion geometrically. Each point is the location of an
event, all of which together represent “the world” through time; paths in the
continuum worldlines represent the dynamical histories of moving particles, so
that straight worldlines correspond to uniform motions; three-dimensional
sections of constant time value “spacelike hypersurfaces” or “simultaneity
slices” represent all of space at a given time. The idea was foreshadowed when
Kant represented “the phenomenal world” as a plane defined by space and time as
perpendicular axes Inaugural Dissertation, 1770, and when Joseph Louis Lagrange
17361814 referred to mechanics as “the analytic geometry of four dimensions.”
But classical mechanics assumes a universal standard of simultaneity, and so it
can treat space and time separately. The concept of space-time was explicitly
developed only when Einstein criticized absolute simultaneity and made the
velocity of light a universal constant. The mathematician Hermann Minkowski
showed in 8 that the observer-independent structure of special relativity could
be represented by a metric space of four dimensions: observers in relative
motion would disagree on intervals of length and time, but agree on a
fourdimensional interval combining spatial and temporal measurements.
Minkowski’s model then made possible the general theory of relativity, which
describes gravity as a curvature of spacetime in the presence of mass and the
paths of falling bodies as the straightest worldlines in curved
space-time.
spatio-temporal
continuity, a property of the careers, or space-time paths, of well-behaved
objects. Let a space-time path be a series of possible spatiotemporal
positions, each represented in a selected coordinate system by an ordered pair
consisting of a time its temporal component and a volume of space its spatial
component. Such a path will be spatiotemporally continuous provided it is such
that, relative to any inertial frame selected as coordinate system, space,
absolute spatiotemporal continuity 867
867 1 for every segment of the series, the temporal components of the
members of that segment form a continuous temporal interval; and 2 for any two
members ‹ti, Vi and ‹tj, Vj of the series that differ in their temporal
components ti and tj, if Vi and Vj the spatial components differ in either
shape, size, or location, then between these members of the series there will
be a member whose spatial component is more similar to Vi and Vj in these
respects than these are to each other. This notion is of philosophical interest
partly because of its connections with the notions of identity over time and
causality. Putting aside such qualifications as quantum considerations may
require, material objects at least macroscopic objects of familiar kinds
apparently cannot undergo discontinuous change of place, and cannot have
temporal gaps in their histories, and therefore the path through space-time
traced by such an object must apparently be spatiotemporally continuous. More
controversial is the claim that spatiotemporal continuity, together with some
continuity with respect to other properties, is sufficient as well as necessary
for the identity of such objects e.g.,
that if a spatiotemporally continuous path is such that the spatial component
of each member of the series is occupied by a table of a certain description at
the time that is the temporal component of that member, then there is a single
table of that description that traces that path. Those who deny this claim
sometimes maintain that it is further required for the identity of material
objects that there be causal and counterfactual dependence of later states on
earlier ones ceteris paribus, if the table had been different yesterday, it
would be correspondingly different now. Since it appears that chains of
causality must trace spatiotemporally continuous paths, it may be that insofar
as spatiotemporal continuity is required for transtemporal identity, this is
because it is required for transtemporal causality.
specious present, the
supposed time between past and future. The term was first offered by E. R. Clay
in The Alternative: A Study in Psychology 2, and was cited by James in Chapter
XV of his Principles of Psychology 0. Clay challenges the assumption that the
“present” as a “datum” is given as “present” to us in our experience. “The
present to which the datum refers is really a part of the past a recent past
delusively given as benign time that intervenes between the past and the
future. Let it be named the specious present, and let the past that is given as
being the past be known as the obvious past.” For James, this position is
supportive of his contention that consciousness is a stream and can be divided
into parts only by conceptual addition, i.e., only by our ascribing past,
present, and future to what is, in our actual experience, a seamless flow.
James holds that the “practically cognized present is no knife-edge but a
saddleback,” a sort of “ducatum” which we experience as a whole, and only upon
reflective attention do we “distinguish its beginning from its end.” Whereas
Clay refers to the datum of the present as “delusive,” one might rather say that
it is perpetually elusive, for as we have our experience, now, it is always
bathed retrospectively and prospectively. Contrary to common wisdom, no single
experience ever is had by our consciousness utterly alone, single and without
relations, fore and aft.
speculative philosophy, a
form of theorizing that goes beyond verifiable observation; specifically, a
philosophical approach informed by the impulse to construct a grand narrative
of a worldview that encompasses the whole of reality. Speculative philosophy
purports to bind together reflections on the existence and nature of the
cosmos, the psyche, and God. It sets for its goal a unifying matrix and an
overarching system wherespeaker’s meaning speculative philosophy 868 868 with to comprehend the considered
judgments of cosmology, psychology, and theology. Hegel’s absolute idealism,
particularly as developed in his later thought, paradigmatically illustrates
the requirements for speculative philosophizing. His system of idealism offered
a vision of the unity of the categories of human thought as they come to
realization in and through their opposition to each other. Speculative thought
tends to place a premium on universality, totality, and unity; and it tends to
marginalize the concrete particularities of the natural and social world. In
its aggressive use of the systematic principle, geared to a unification of
human experience, speculative philosophy aspires to a comprehensive
understanding and explanation of the structural interrelations of the culture
spheres of science, morality, art, and religion.
Austinianism -- speech
act theory, the theory of language use, sometimes called pragmatics, as opposed
to the theory of meaning, or semantics. Based on the meaninguse distinction, it
categorizes systematically the sorts of things that can be done with words and
explicates the ways these are determined, underdetermined, or undetermined by
the meanings of the words used. Relying further on the distinction between
speaker meaning and linguistic meaning, it aims to characterize the nature of
communicative intentions and how they are expressed and recognized. Speech acts
are a species of intentional action. In general, one and the same utterance may
comprise a number of distinct though related acts, each corresponding to a
different intention on the part of the speaker. Beyond intending to produce a
certain sequence of sounds forming a sentence in English, a person who utters
the sentence ‘The door is open’, e.g., is likely to be intending to perform, in
the terminology of J. L. Austin How to Do Things with Words, 2, 1 the
locutionary act of saying expressing the proposition that a certain door is
open, 2 the illocutionary act of making the statement expressing the belief
that it is open, and 3 the perlocutionary act of getting his listener to
believe that it is open. In so doing, he may be performing the indirect speech
act of requesting illocutionary the listener to close the door and of getting
perlocutionary the hearer to close the door. The primary focus of speech act
theory is on illocutionary acts, which may be classified in a variety of ways.
Statements, predictions, and answers exemplify constatives; requests, commands
and permissions are directives; promises, offers, and bets are commissives;
greetings, apologies, and congratulations are acknowledgments. These are all
communicative illocutionary acts, each distinguished by the type of
psychological state expressed by the speaker. Successful communication consists
in the audience’s recognition of the speaker’s intention to be expressing a
certain psychological state with a certain content. Conventional illocutionary
acts, on the other hand, effect or officially affect institutional states of
affairs. Examples of the former are appointing, resigning, sentencing, and
adjourning; examples of the latter are assessing, acquitting, certifying, and
grading. See Kent Bach and Robert M. Harnish, Linguistic Communication and
Speech Acts, 9. The type of act an utterance exemplifies determines its
illocutionary force. In the example ‘The door is open’, the utterance has the
force of both a statement and a request. The illocutionary force potential of a
sentence is the force or forces with which it can be used literally, e.g., in
the case of the sentence ‘The door is open’, as a statement but not as a
request. The felicity conditions on an illocutionary act pertain not only to
its communicative or institutional success but also to its sincerity,
appropriateness, and effectiveness. An explicit performative utterance is an illocutionary
act performed by uttering an indicative sentence in the simple present tense
with a verb naming the type of act being performed, e.g., ‘I apologize for
everything I did’ and ‘You are requested not to smoke’. The adverb ‘hereby’ may
be used before the performative verb ‘apologize’ and ‘request’ in these
examples to indicate that the very utterance being made is the vehicle of the
performance of the illocutionary act in question. A good test for
distinguishing illocutionary from perlocutionary acts is to determine whether a
verb naming the act can be used performatively. Austin exploited the phenomenon
of performative utterances to expose the common philosophical error of assuming
that the primary use of language is to make statements.
Spencer, Herbert 18203,
English philosopher, social reformer, and editor of The Economist. In
epistemology, Spencer adopted the ninespeculative reason Spencer, Herbert
869 869 teenth-century trend toward
positivism: the only reliable knowledge of the universe is to be found in the
sciences. His ethics were utilitarian, following Bentham and J. S. Mill:
pleasure and pain are the criteria of value as signs of happiness or
unhappiness in the individual. His Synthetic Philosophy, expounded in books
written over many years, assumed both in biology and psychology the existence
of Lamarckian evolution: given a characteristic environment, every animal
possesses a disposition to make itself into what it will, failing maladaptive
interventions, eventually become. The dispositions gain expression as inherited
acquired habits. Spencer could not accept that species originate by chance
variations and natural selection alone: direct adaptation to environmental
constraints is mainly responsible for biological changes. Evolution also
includes the progression of societies in the direction of a dynamical
equilibrium of individuals: the human condition is perfectible because human
faculties are completely adapted to life in society, implying that evil and
immorality will eventually disappear. His ideas on evolution predated
publication of the major works of Darwin; A. R. Wallace was influenced by his
writings.
