IMPLICATVRA, in 18 volumes -- vol. 13



open-close distinction, the: open formula: also called open sentence, a sentence with a free occurrence of a variable. A closed sentence, sometimes called a ‘statement,’ has no free occurrences of variables. In a language whose only variable-binding operators are quantifiers, an occurrence of a variable in a formula is bound provided that occurrence either is within the scope of a quantifier employing that variable or is the occurrence in that quantifier. An occurrence of a variable in a formula is free provided it is not bound. The formula ‘xy  O’ is open because both ‘x’ and ‘y’ occur as free variables. In ‘For some real number y, xy  O’, no occurrence of ‘y’ is free; but the occurrence of ‘x’ is free, so the formula is open. The sentence ‘For every real number x, for some real number y, xy  O’ is closed, since none of the variables occur free. Semantically, an open formula such as ‘xy  0’ is neither true nor false but rather true of or false of each assignment of values to its free-occurring variables. For example, ‘xy  0’ is true of each assignment of two positive or two negative real numbers to ‘x’ and to ‘y’ and it is false of each assignment of 0 to either and false at each assignment of a positive real to one of the variables and a negative to the other.

porosität: porosity -- open texture, the possibility of vagueness. Waismann “Verifiability,” Proceedings of the Aristotelian Society, introduced the metaphor, claiming that open texture is a universal property of empirical terms. Waismann claims that an inexhaustible source of vagueness remains even after measures are taken to make an expression precise. His grounds were, first, that there are an indefinite number of possibilities for which it is indeterminate whether the expression applies i.e., for which the expression is vague. There is, e.g., no definite answer whether a catlike creature that repeatedly vanishes into thin air, then reappears, is a cat. Waismann’s explanation is that when we define an empirical term, we frame criteria of its applicability only for foreseeable circumstances. Not all possible situations in which we may use the term, however, can be foreseen. Thus, in unanticipated circumstances, real or merely possible, a term’s criteria of applicability may yield no definite answer to whether it applies. Second, even for terms such as ‘gold’, for which there are several precise criteria of application specific gravity, X-ray spectrograph, solubility in aqua regia, applying different criteria can yield divergent verdicts, the result being vagueness. Waismann uses the concept of open texture to explain why experiential statements are not conclusively verifiable, and why phenomenalist attempts to translate material object statements fail.  Waismanns Konzept der offenen Struktur oder Porosität, hat in der ... πόρος , ὁ, (πείρω, περάω) A.means of passing a river, ford, ferry, Θρύον Ἀλφειοῖο π.

operationalism: a program in philosophy of science that aims to interpret scientific concepts via experimental procedures and observational outcomes. P. W. Bridgman introduced the terminology when he required that theoretical concepts be identified with the operations used to measure them. Logical positivism’s criteria of cognitive significance incorporated the notion: Bridgman’s operationalism was assimilated to the positivistic requirement that theoretical terms T be explicitly defined via logically equivalent to directly observable conditions O. Explicit definitions failed to accommodate alternative measurement procedures for the same concept, and so were replaced by reduction sentences that partially defined individual concepts in observational terms via sentences such as ‘Under observable circumstances C, x is T if and only if O’. Later this was weakened to allow ensembles of theoretical concepts to be partially defined via interpretative systems specifying collective observable effects of the concepts rather than effects peculiar to single concepts. These cognitive significance notions were incorporated into various behaviorisms, although the term ‘operational definition’ is rarely used by scientists in Bridgman’s or the explicit definition senses: intervening variables are theoretical concepts defined via reduction sentences and hypothetical constructs are definable by interpretative systems but not reduction sentences. In scientific contexts observable terms often are called dependent or independent variables. When, as in science, the concepts in theoretical assertions are only partially defined, observational consequences do not exhaust their content, and so observational data underdetermines the truth of such assertions in the sense that more than one theoretical assertion will be compatible with maximal observational data. 

Operatum – “Unoriginally, I will use “O” to symbolise an ‘operator’” – Grice. if you have an operaturm, you also have an operator – operans, operaturum, operandum, operatum – The operans is like the operator: a one-place sentential connective; i.e., an expression that may be prefixed to an open or closed sentence to produce, respectively, a new open or closed sentence. Thus ‘it is not the case that’ is a truth-functional operator. The most thoroughly investigated operators are the intensional ones; an intensional operator O, when prefixed to an open or closed sentence E, produces an open or closed sentence OE, whose extension is determined not by the extension of E but by some other property of E, which varies with the choice of O. For example, the extension of a closed sentence is its truth-value A, but if the modal operator ‘it is necessary that’ is prefixed to A, the extension of the result depends on whether A’s extension belongs to it necessarily or contingently. This property of A is usually modeled by assigning to A a subset X of a domain of possible worlds W. If X % W then ‘it is necessary that A’ is true, but if X is a proper subset of W, it is false. Another example involves the epistemic operator ‘it is plausible that’. Since a true sentence may be either plausible or implausible, the truth-value of ‘it is plausible that A’ is not fixed by the truth-value of A, but rather by the body of evidence that supports A relative to a thinker in a given context. This may also be modeled in a possible worlds framework, by operant conditioning operator 632    632 stipulating, for each world, which worlds, if any, are plausible relative to it. The topic of intensional operators is controversial, and it is even disputable whether standard examples really are operators at the correct level of logical form. For instance, it can be argued that ‘it is necessary that’, upon analysis, turns out to be a universal quantifier over possible worlds, or a predicate of expressions. On the former view, instead of ‘it is necessary that A’ we should write ‘for every possible world w, Aw’, and, on the latter, ‘A is necessarily true’. 

adverb – for the speculative grammarian like Alcuin, or Occam, a part of speech – pars orationis – surely not one of Plato’s basic ones! -- operator theory of adverbs, a theory that treats adverbs and other predicate modifiers as predicate-forming operators on predicates. The theory expands the syntax of first-order predicate calculus of identity – Sytem G, Gricese -- by adding operators of various degrees, and makes corresponding additions to the semantics. Romane Clark, Terence Parsons, and Richard Montague with Hans Kamp developed the theory independently. Grice discusses it in “Actions and events.” For example: ‘John runs quickly through the kitchen’ contains a simple one-place predicate, ‘runs’ applied to John; a zero-place operator, ‘quickly’, and a one-place operator, ‘through ’ with ‘the kitchen’ filling its place. The semantics of the expression becomes [O1 1a [O2 0 [Pb]]], which can be read as “[through the kitchen [quickly [runs John]]]. Semantically ‘quickly’ will be associated with an operation that takes us from the extension of ‘runs’ to a subset of that extension. ‘John runs quickly’ entails, but does not implicate, ‘John runs’. ‘Through the kitchen’ and other operators are handled similarly. The wide variety of predicate modifiers complicates the inferential conditions and semantics of the operators. ‘John is finally done’ entails, but does not implicate, ‘John is done’. Oddly, ‘John is nearly done’ or “John is hardly done” entails, but does not implicate ‘John is not done’ (whereas “John is hardly done” entails that it is not the case that John is done. Clark tries to distinguish various types of predicate modifiers and provides a different semantic analysis for operators of different sorts. The theory can easily characterize syntactic aspects of predicate modifier iteration. In addition, after being modified the original predicates remain as predicates, and maintain their original degree. Further, there is no need to force John’s running into subject position as might be the case if we try to make ‘quickly’ an ordinary predicate. Refs.: Grice, “Actiosn and events,” H. P. Grice, “Why adverbs matter to philosophy,” Grice, “The semantics of action.” Grice, “Austin on Mly.” --

optimum. Grice: “We must distinguish between the optimum, the maximum, and the satisficing!” -- If (a) S accepts at t an alethic acceptability-conditional C 1 , the antecedent of which favours, to degree d, the consequent of C 1 , (b) S accepts at t the antecedent of C 1 , end p.81 (c) after due search by S for such a (further) conditional, there is no conditional C 2 such that (1) S accepts at t C 2 and its antecedent, (2) and the antecedent of C 2 is an extension of the antecedent of C 1 , (3) and the consequent of C 2 is a rival (incompatible with) of the consequent of C 1 , (4) and the antecedent of C 2 favours the consequent of C 2 more than it favours the consequent of C 1 : then S may judge (accept) at t that the consequent of C 1 is acceptable to degree d. For convenience, we might abbreviate the complex clause (C) in the antecedent of the above rule as 'C 1 is optimal for S at t'; with that abbreviation, the rule will run: "If S accepts at t an alethic acceptability-conditional C 1 , the antecedent of which favours its consequent to degree d, and S accepts at t the antecedent of C 1 , and C 1 is optimal for S at C 1 , then S may accept (judge) at t that the consequent of C 1 is acceptable to degree d." Before moving to the practical dimension, I have some observations to make.See validum. For Grice, the validum can attain different shapes or guises. One is the optimum. He uses it for “Emissor E communicates thata p” which ends up denotating an ‘ideal,’ that can only be deemed, titularily, to be present ‘de facto.’ The idea is that of the infinite, or rather self-reference regressive closure. Vide Blackburn on “open GAIIB.” Grice uses ‘optimality’ as one guise of value. Obviously, it is, as Short and Lewis have it, the superlative of ‘bonum,’ so one has to be careful. Optimum is used in value theory and decision theory, too.  Cf. Maximum, and minimax. In terms of the principle of least conversational effort, the optimal move is the least costly. To utter, “The pillar box seems red” when you can utter, “The pillar box IS red” is to go into the trouble when you shouldn’t. So this maximin regulates the conversational exchange. The utterer is meant to be optimally efficient, and the addressee is intended to recognise that.

order: the level of a system as determined by the type of entity over which the free variables of that logic range. Entities of the lowest type, usually called type O, are known as individuals, and entities of higher type are constructed from entities of lower type. For example, type 1 entities are i functions from individuals or n-tuples of individuals to individuals, and ii n-place relations on individuals. First-order logic is that logic whose variables range over individuals, and a model for first-order logic includes a domain of individuals. The other logics are known as higher-order logics, and the first of these is second-order logic, in which there are variables that range over type 1 entities. In a model for second-order logic, the first-order domain determines the second-order domain. For every sentence to have a definite truth-value, only totally defined functions are allowed in the range of second-order function variables, so these variables range over the collection of total functions from n-tuples of individuals to individuals, for every value of n. The second-order predicate variables range over all subsets of n-tuples of individuals. Thus if D is the domain of individuals of a model, the type 1 entities are the union of the two sets {X: Dn: X 0 Dn$D}, {X: Dn: X 0 Dn}. Quantifiers may bind second-order variables and are subject to introduction and elimination rules. Thus whereas in first-order logic one may infer ‘Someone is wise, ‘DxWx’, from ‘Socrates is wise’, ‘Ws’, in second-order logic one may also infer ‘there is something that Socrates is’, ‘DXXs’. The step from first- to second-order logic iterates: in general, type n entities are the domain of n ! 1thorder variables in n ! 1th order logic, and the whole hierarchy is known as the theory of types.

ordering: an arrangement of the elements of a set so that some of them come before others. If X is a set, it is useful to identify an ordering R of X with a subset R of X$X, the set of all ordered pairs with members in X. If ‹ x,y  1 R then x comes before y in the ordering of X by R, and if ‹ x,y  2 R and ‹ y,x  2 R, then x and y are incomparable. Orders on X are therefore relations on X, since a relation on a set X is any subset of X $ X. Some minimal conditions a relation must meet to be an ordering are i reflexivity: ExRxx; ii antisymmetry: ExEyRxy & Ryx / x % y; and iii transitivity: ExEyEzRxy & Ryz / Rxz. A relation meeting these three conditions is known as a partial order also less commonly called a semi-order, and if reflexivity is replaced by irreflexivity, Ex-Rxx, as a strict partial order. Other orders are strengthenings of these. Thus a tree-ordering of X is a partial order with a distinguished root element a, i.e. ExRax, and that satisfies the backward linearity condition that from any element there is a unique path back to a: ExEyEzRyx & Rzx / Ryz 7 Rzy. A total order on X is a partial order satisfying the connectedness requirement: ExEyRxy 7 Ryx. Total orderings are sometimes known as strict linear orderings, contrasting with weak linear orderings, in which the requirement of antisymmetry is dropped. The natural number line in its usual order is a strict linear order; a weak linear ordering of a set X is a strict linear order of levels on which various members of X may be found, while adding antisymmetry means that each level contains only one member. Two other important orders are dense partial or total orders, in which, between any two elements, there is a third; and well-orders. A set X is said to be well-ordered by R if R is total and every non-empty subset of Y of X has an R-least member: EY 0 X[Y & / / Dz 1 YEw 1 YRzw]. Well-ordering rules out infinite descending sequences, while a strict well-ordering, which is irreflexive rather than reflexive, rules out loops. The best-known example is the membership relation of axiomatic set theory, in which there are no loops such as x 1 y 1 x or x 1 x, and no infinite descending chains . . . x2 1 x1 1 x0. 

order type omega: in mathematics, the order type of the infinite set of natural numbers. The last letter of the Grecian alphabet, w, is used to denote this order type; w is thus the first infinite ordinal number. It can be defined as the set of all finite ordinal numbers ordered by magnitude; that is, w % {0,1,2,3 . . . }. A set has order type w provided it is denumerably infinite, has a first element but not a last element, has for each element a unique successor, and has just one element with no immediate predecessor. The set of even numbers ordered by magnitude, {2,4,6,8 . . . }, is of order type w. The set of natural numbers listing first all even numbers and then all odd numbers, {2,4,6,8 . . .; 1,3,5,7 . . . }, is not of order type w, since it has two elements, 1 and 2, with no immediate predecessor. The set of negative integers ordered by magnitude, { . . . 3,2,1}, is also not of order type w, since it has no first element. V.K. ordinal logic, any means of associating effectively and uniformly a logic in the sense of a formal axiomatic system Sa with each constructive ordinal notation a. This notion and term for it was introduced by Alan Turing in his paper “Systems of Logic Based on Ordinals” 9. Turing’s aim was to try to overcome the incompleteness of formal systems discovered by Gödel in 1, by means of the transfinitely iterated, successive adjunction of unprovable but correct principles. For example, according to Gödel’s second incompleteness theorem, for each effectively presented formal system S containing a modicum of elementary number theory, if S is consistent then S does not prove the purely universal arithmetical proposition Cons expressing the consistency of S via the Gödelnumbering of symbolic expressions, even though Cons is correct. However, it may be that the result S’ of adjoining Cons to S is inconsistent. This will not happen if every purely existential statement provable in S is correct; call this condition E-C. Then if S satisfies E-C, so also does S; % S ! Cons ; now S; is still incomplete by Gödel’s theorem, though it is more complete than S. Clearly the passage from S to S; can be iterated any finite number of times, beginning with any S0 satisfying E-C, to form S1 % S; 0, S2 % S; 1, etc. But this procedure can also be extended into the transfinite, by taking Sw to be the union of the systems Sn for n % 0,1, 2 . . . and then Sw!1 % S;w, Sw!2 % S;w!1, etc.; condition EC is preserved throughout. To see how far this and other effective extension procedures of any effectively presented system S to another S; can be iterated into the transfinite, one needs the notion of the set O of constructive ordinal notations, due to Alonzo Church and Stephen C. Kleene in 6. O is a set ordering ordinal logic 634    634 of natural numbers, and each a in O denotes an ordinal a, written as KaK. There is in O a notation for 0, and with each a in O is associated a notation sca in O with KscaK % KaK ! 1; finally, if f is a number of an effective function {f} such that for each n, {f}n % an is in O and KanK < Kan!1K, then we have a notation øf in O with KøfK % limnKanK. For quite general effective extension procedures of S to S; and for any given S0, one can associate with each a in O a formal system Sa satisfying Ssca % S;a and Søf % the union of the S{f}n for n % 0,1, 2. . . . However, as there might be many notations for each constructive ordinal, this ordinal logic need not be invariant, in the sense that one need not have: if KaK % KbK then Sa and Sb have the same consequences. Turing proved that an ordinal logic cannot be both complete for true purely universal statements and invariant. Using an extension procedure by certain proof-theoretic reflection principles, he constructed an ordinal logic that is complete for true purely universal statements, hence not invariant. The history of this and later work on ordinal logics is traced by the undersigned in “Turing in the Land of Oz,” in The Universal Turing Machine: A Half Century Survey, edited by Rolf Herken.

‘ordinary’-language philosophy: “I never knew what language Austin meant – Greek most likely, given his background!” – Grice prefers ‘vernacular,’ which is charming. Back in Oxford, Occam had to struggle against his vernacular (“Englysse”) and speak Roman! Then Latin was the lingua franca, i.e . tongue of the Franks!  vide, H. P. Grice, “Post-War Oxford Philosophy,” a loosely structured philosophical movement holding that the significance of concepts, including those central to traditional philosophy  e.g., the concepts of truth and knowledge  is fixed by linguistic practice. Philosophers, then, must be attuned to the actual uses of words associated with these concepts. The movement enjoyed considerable prominence chiefly among English-speaking philosophers between the mid-0s and the early 0s. It was initially inspired by the work of Vitters, and later by John Wisdom, Gilbert Ryle, Norman Malcolm, J. L. Austin and H. P. Grice, though its roots go back at least to Moore and arguably to Socrates. ‘Ordinary’-language philosophers do not mean to suggest that, to discover what truth is, we are to poll our fellow speakers or consult dictionaries (“Naess philosopher is not” – Grice). Rather, we are to ask how the word ‘truth’ functions in everyday, nonphilosophical settings. A philosopher whose theory of truth is at odds with ordinary usage has simply misidentified the concept. Philosophical error, ironically, was thought by Vitters to arise from our “bewitchment” by language. When engaging in philosophy, we may easily be misled by superficial linguistic similarities. We suppose minds to be special sorts of entity, for instance, in part because of grammatical parallels between ‘mind’ and ‘body’. When we fail to discover any entity that might plausibly count as a mind, we conclude that minds must be nonphysical entities. The cure requires that we remind ourselves how ‘mind’ and its cognates are actually used by ordinary speakers. Refs.: H. P. Grice, “Post-war Oxford philosophy,” “Conceptual analysis and the province of philosophy.”

organic: having parts that are organized and interrelated in a way that is the same as, or analogous to, the way in which the parts of a living animal or other biological organism are organized and interrelated. Thus, an organic unity or organic whole is a whole that is organic in the above sense. These terms are primarily used of entities that are not literally organisms but are supposedly analogous to them. Among the applications of the concept of an organic unity are: to works of art, to the state e.g., by Hegel, and to the universe as a whole e.g., in absolute idealism. The principal element in the concept is perhaps the notion of an entity whose parts cannot be understood except by reference to their contribution to the whole entity. Thus to describe something as an organic unity is typically to imply that its properties cannot be given a reductive explanation in terms of those of its parts; rather, at least some of the properties of the parts must themselves be explained by reference to the properties of the whole. Hence it usually involves a form of holism. Other features sometimes attributed to organic unities include a mutual dependence between the existence of the parts and that of the whole and the need for a teleological explanation of properties of the parts in terms of some end or purpose associated with the whole. To what extent these characteristics belong to genuine biological organisms is disputed. 

organicism, a theory that applies the notion of an organic unity, especially to things that are not literally organisms. G. E. Moore, in Principia Ethica, proposed a principle of organic unities, concerning intrinsic value: the intrinsic value of a whole need not be equivalent to the sum of the intrinsic values of its parts. Moore applies the principle in arguing that there is no systematic relation between the intrinsic value of an element of a complex whole and the difference that the presence of that element makes to the value of the whole. E.g., he holds that although a situation in which someone experiences pleasure in the contemplation of a beautiful object has far greater intrinsic goodness than a situation in which the person contemplates the same object without feeling pleasure, this does not mean that the pleasure itself has much intrinsic value.

organism, a carbon-based living thing or substance, e.g., a paramecium, a tree, or an ant. Alternatively, ‘organism’ can mean, as in a typical Gricean gedenke experiment,  a hypothetical living thing of another natural kind, e.g., a silicon-based living thing, in sum, a pirot – “Pirots karulise elatically.” -- Defining conditions of a carbon-based living thing, x, are as follows. 1 x has a layer made of m-molecules, i.e., carbonbased macromolecules of repeated units that have a high capacity for selective reactions with other similar molecules. x can absorb and excrete through this layer. 2 x can metabolize m-molecules. 3 x can synthesize m-molecular parts of x by means of activities of a proper part of x that is a nuclear molecule, i.e., an m-molecule that can copy itself. 4 x can exercise the foregoing capacities in such a way that the corresponding activities are causally interrelated as follows: x’s absorption and excretion causally contribute to x’s metabolism; these processes jointly causally contribute to x’s synthesizing; and x’s synthesizing causally contributes to x’s absorption, excretion, and metabolism. 5 x belongs to a natural kind of compound physical substance that can have a member, y, such that: y has a proper part, z; z is a nuclear molecule; and y reproduces by means of z’s copying itself. 6 x is not possibly a proper part of something that satisfies 16. The last condition expresses the independence and autonomy of an organism. For example, a part of an organism, e.g., a heart cell, is not an organism. It also follows that a colony of organisms, e.g., a colony of ants, is not an organism. 

Origen (vide Patrologia – series Graeca – Migne) -- he became head of the catechetical school in Alexandria. Like his mentor, Clement of Alexandria, he was influenced by Middle Platonism. His principal works were Hexapla, On First Principles, and Contra Celsum. The Hexapla, little of which survives, consisted of six Hebrew and two Grecian versions of the Old Testament with Origen’s commentary. On First Principles sets forth the most systematic Christian theology of the early church, including some doctrines subsequently declared heretical, such as the subordination of the Son “a secondary god” and Spirit to the Father, preexisting human souls but not their transmigration, and a premundane fall from grace of each human soul. The most famous of his views was the notion of apocatastasis, universal salvation, the universal restoration of all creation to God in which evil is defeated and the devil and his minions repent of their sins. He interpreted hell as a temporary purgatory in which impure souls were purified and made ready for heaven. His notion of subordination of the Son of God to the Father was condemned by the church in 533. Origen’s Contra Celsum is the first sustained work in Christian apologetics. It defends Christianity before the pagan world. Origen was a leading exponent of the allegorical interpretation of the Scriptures, holding that the text had three levels of meaning corresponding to the three parts of human nature: body, soul, and spirit. The first was the historical sense, sufficient for simple people; the second was the moral sense; and the third was the mystical sense, open only to the deepest souls.

Orphism – ovvero Orfeo a Crotone -- or as Grice preferred Orpheusianism --  a religious movement in ancient Graeco-Roman culture that may have influenced Plato and some of the pre-Socratics. Neither the nature of the movement nor the scope of its influence is adequately understood: ancient sources and modern scholars tend to confuse Orphism with the Pythagoreanism school led by the native Crotonian “Filolao” at Crotone, and with ancient mystery cults, especially the Bacchic or Dionysiac mysteries. “Orphic poems,” i.e., poems attributed to Orpheus a mythic figure, circulated as early as the mid-sixth century B.C. We have only indirect evidence of the early Orphic poems; but we do have a sizable body of fragments from poems composed in later antiquity. Central to both early and later versions is a theogonic-cosmogonic narrative that posits Night (Nox) as the primal entity  ostensibly a revision of the account offered by Hesiod  and gives major emphasis to the birth, death through dismemberment, and rebirth of the god Dionysus, that the Romans called Bacchus. Plato gives us clear evidence of the existence in his time of itinerant religious teachers who, drawing on the “books of Orpheus,” performed and taught rituals of initiation and purification intended to procure divine favor either in this life or in an afterlife. The extreme skepticism of such scholars as Ulrich von Wilamowitz-Moellendorff and I. M. Linforth concerning the importance of early Orphism for Graeco-Roman religion and Graeco-Roman philosophy has been undermined by archaeological findings in recent decades: the Derveni papyrus, which is a fragment of a philosophical commentary on an Orphic theogony; and inscriptions with Orphic instructions for the dead, from a funerary sites Crotone.

ostensum: In his analysis of the two basic procedures, one involving the subjectum, and another the praedicatum, Grice would play with the utterer OSTENDING that p. This relates to his semiotic approach to communication, and avoiding to the maximum any reference to a linguistic rule or capacity or faculty as different from generic rationality. In WoW:134 Grice explores what he calls ‘ostensive correlation.’ He is exploring communication scenarios where the Utterer is OSTENDING that p, or in predicate terms, that the A is B. He is not so much concerned with the B, but with the fact that “B” is predicated of a particular denotatum of “the A,” and by what criteria. He is having in mind his uncle’s dog, Fido, who is shaggy, i.e. fairy coated. So he is showing to Strawson that that dog over there is the one that belongs to his uncle, and that, as Strawson can see, is a shaggy dog, by which Grice means hairy coated. That’s the type of ‘ostensive correlation’ Grice is having in mind. In an attempted ostensive correlation of the predicate B (‘shaggy’) with the feature or property of being hairy coated, as per a standard act of communication in which Grice, uttering, “Fido is shaggy’ will have Strawson believe that Uncle Grice’s dog is hairy coated – (1) U will perform a number of acts in each of which he ostends a thing  (a1, a2, a3, etc.). (2) Simultaneously with each ostension, he utters a token of the predicate “shaggy.” (3) It is his intention TO OSTEND, and to be recognised as ostending, only things which are either, in his view, plainly hairy-coated, or are, in his view, plainly NOT hairy-coated. (4) In a model sequence these intentions are fulfilled. Grice grants that this does not finely distinguish between ‘being hairy-coated’ from ‘being such that the UTTERER believes to be unmistakenly hairy coated.’ But such is a problem of any explicit correlation, which are usually taken for granted – and deemed ‘implicit’ in standard acts of communication.

merton: Oxford Calculators, a group of philosophers who flourished at Oxford. The name derives from the “Liber calculationum.”. The author of this work, often called “Calculator” by later Continental authors, is Richard Swineshead. The “Liber calculationum” discussed a number of issues related to the quantification or measurement of local motion, alteration, and augmentation for a fuller description – v. Murdoch and Sylla, “Swineshead” in Dictionary of Scientific Biography. The “Liber calculationum” has been studied mainly by historians of science and grouped together with a number of other works discussing natural philosophical topics by such authors as Bradwardine, Heytesbury, and Dumbleton. In earlier histories many of the authors now referred to as Oxford Calculators are referred to as “The Merton School,” since many of them were fellows of Merton . But since some authors whose oeuvre appears to fit into the same intellectual tradition e.g., Kilvington, whose “Sophismata” represents an earlier stage of the tradition later epitomized by Heytesbury’s Sophismata have no known connection with Merton , ‘Oxford Calculators’ would appear to be a more accurate appellation. The works of the Oxford Calculators or Mertonians – Grice: “I rather deem Kilvington a Mertonian than change the name of his school!” -- were produced in the context of education in the Oxford arts faculty – Sylla --  “The Oxford Calculators,” in Kretzmann, Kenny, and Pinborg, eds., The Cambridge History of Later Medieval Philosophy. At Oxford semantics is the centerpiece of the Lit. Hum. curriculum. After semantics, Oxford came to be known for its work in mathematics, astronomy, and natural philosophy. Students studying under the Oxford faculty of arts not only heard lectures on the seven liberal arts and on natural philosophy, moral philosophy, and metaphysics. They were also required to take part in disputations. Heytesbury’s “Regule solvendi sophismatum” explicitly and Swineshead’s “Liber calculationum” implicitly are written to prepare students for these disputations. The three influences most formative on the work of the Oxford Calculators were the tradition of commentaries on the works of Aristotle; the developments in semantics, particularly the theories of categorematic and syncategorematic terms and the theory of conseequentia, implicate, and supposition; and and the theory of ratios as developed in Bradwardine’s De proportionibus velocitatum in motibus. In addition to Swineshead, Heytesbury, Bradwardine, Dumbleton, and Kilvington, other authors and works related to the work of the Oxford Calculators are Burleigh, “De primo et ultimo instanti, Tractatus Primus De formis accidentalibus, Tractatus Secundus De intensione et remissione formarum; Swineshead, Descriptiones motuum; and Bode, “A est unum calidum.” These and other works had a considerable later influence on the Continent.  Refs.: H. P. Grice, “Sophismata in the Liber calculationum,” H. P. Grice, “My days at Merton.” – H. P. Grice, “Merton made me.” – H. P. Grice, “Merton and post-war Oxford philosophy.”

esse -- ousia: The abstractum behind Grice’s ‘izz’ --. Grecian term traditionally tr. as ‘substance,’ although the strict transliteration is ‘essentia,’ a feminine abstract noun out of the verb ‘esse.’ Formed from the participle for ‘being’, the term ousia refers to the character of being, beingness, as if this were itself an entity. Just as redness is the character that red things have, so ousia is the character that beings have. Thus, the ousia of something is the character that makes it be, its nature. But ousia also refers to an entity that possesses being in its own right; for consider a case where the ousia of something is just the thing itself. Such a thing possesses being by virtue of itself; because its being depends on nothing else, it is self-subsistent and has a higher degree of being than things whose being depends on something else. Such a thing would be an ousia. Just which entities meet the criteria for ousia is a question addressed by Aristotle. Something such as redness that exists only as an attribute would not have being in its own right. An individual person is an ousia, but Aristotle also argues that his form is more properly an ousia; and an unmoved mover is the highest type of ousia. The traditional rendering of the term into Latin as substantia and English as ‘substance’ is appropriate only in contexts like Aristotle’s Categories where an ousia “stands under” attributes. In his Metaphysics, where Aristotle argues that being a substrate does not characterize ousia, and in other Grecian writers, ‘substance’ is often not an apt translation. 

outweighed rationality – the grammar – rationality of the end, not just the means – extrinsic rationality – not intrinsic to the means.  -- The intrinsic-extrinsic – outweigh -- extrinsic desire, a desire of something for its conduciveness to something else that one desires. An extrinsic desire is distinguished from an intrinsic desire, a desire of items for their own sake, or as an end. Thus, an individual might desire financial security extrinsically, as a means to her happiness, and desire happiness intrinsically, as an end. Some desires are mixed: their objects are desired both for themselves and for their conduciveness to something else. Jacques may desire to jog, e.g., both for its own sake as an end and for the sake of his health. A desire is strictly intrinsic if and only if its object is desired for itself alone. A desire is strictly extrinsic if and only if its object is not desired, even partly, for its own sake. Desires for “good news”  e.g., a desire to hear that one’s child has survived a car accident  are sometimes classified as extrinsic desires, even if the information is desired only because of what it indicates and not for any instrumental value that it may have. Desires of each kind help to explain action. Owing partly to a mixed desire to entertain a friend, Martha might acquire a variety of extrinsic desires for actions conducive to that goal. Less happily, intrinsically desiring to be rid of his toothache, George might extrinsically desire to schedule a dental appointment. If all goes well for Martha and George, their desires will be satisfied, and that will be due in part to the effects of the desires upon their behavior. 


ordinary language – There are two topics about ordinary language, as anyone who ever consulted a philosophical dictionary will realise. Words like ‘know’ and words like “transcendental deduction.” Is Austin promoting that we stick with ‘know’ and that no technical terms are even allowed for their analysis. We don’t thnk so.. The phatic and the rhetic and the phemic and the illocution and the perlocution are not ‘ordinary’. –as  opposed to ‘ideal’ language -- ideal language, a system of notation that would correct perceived deficiencies of ordinary language by requiring the structure of expressions to mirror the structure of that which they represent. The notion that conceptual errors can be corrected and philosophical problems solved (or dissolved) by properly representing them in some such system figured prominently in the writings of Leibniz, Carnap, Russell, Wittgenstein, and Frege, among others. For Russell, the ideal, or “logically perfect,” language is one in which grammatical form coincides with logical form, there are no vague or ambiguous expres sions, and no proper names that fail to denote. Frege’s Begriffsschrift is perhaps the most thorough and successful execution of the ideal language project. Deductions represented within this system (or its modern descendants) can be effectively checked for correctness.

Oxford idealism: Grice is a member of “The F. H. Bradley Society,” at Mansfield. -- ideal market, a hypothetical market, used as a tool of economic analysis, in which all relevant agents are perfectly informed of the price of the good in question and the cost of its production, and all economic transactions can be undertaken with no cost. A specific case is a market exemplifying perfect competition. The term is sometimes extended to apply to an entire economy consisting of ideal markets for every good.  -- ideal observer, a hypothetical being, possessed of various qualities and traits, whose moral reactions (judgments or attitudes) to actions, persons, and states of affairs figure centrally in certain theories of ethics. There are two main versions of ideal observer theory: (a) those that take the reactions of ideal observers as a standard of the correctness of moral judgments, and (b) those that analyze the meanings of moral judgments in terms of the reactions of ideal observers. Theories of the first sort – ideal observer theories of correctness – hold, e.g., that judgments like ‘John’s lying to Brenda about her father’s death was wrong (bad)’ are correct provided any ideal observer would have a negative attitude toward John’s action. Similarly, ‘Alison’s refusal to divulge confidential information about her patient was right (good)’ is correct provided any ideal observer would have a positive attitude toward that action. This version of the theory can be traced to Adam Smith, who is usually credited with introducing the concept of an ideal observer into philosophy, though he used the expression ‘impartial spectator’ to refer to the concept. Regarding the correctness of moral judgments, Smith wrote: “That precise and distinct measure can be found nowhere but in the sympathetic feelings of the impartial and well-informed spectator” (A Theory of Moral Sentiments, 1759). Theories of a second sort – ideal observer theories of meaning – take the concept of an ideal observer as part of the very meaning of ordinary moral judgments. Thus, according to Roderick Firth (“Ethical Absolutism and the Ideal Observer,” Philosophy and Phenomenological Research, 1952), moral judgments of the form ‘x is good (bad)’, on this view, mean ‘All ideal observers would feel moral approval (disapproval) toward x’, and similarly for other moral judgments (where such approvals and disapprovals are characterized as felt desires having a “demand quality”). Different conceptions of an ideal observer result from variously specifying those qualities and traits that characterize such beings. Smith’s characterization includes being well informed and impartial. However, according to Firth, an ideal observer must be omniscient; omnipercipient, i.e., having the ability to imagine vividly any possible events or states of affairs, including the experiences and subjective states of others; disinterested, i.e., having no interests or desires that involve essential reference to any particular individuals or things; dispassionate; consistent; and otherwise a “normal” human being. Both versions of the theory face a dilemma: on the one hand, if ideal observers are richly characterized as impartial, disinterested, and normal, then since these terms appear to be moral-evaluative terms, appeal to the reactions of ideal observers (either as a standard of correctness or as an analysis of meaning) is circular. On the other hand, if ideal observers receive an impoverished characterization in purely non-evaluative terms, then since there is no reason to suppose that such ideal observers will often all agree in their reactions to actions, people, and states of affairs, most moral judgments will turn out to be incorrect. Grice: “We have to distinguish between idealism and hegelianism; but the English being as they are, they don’t! And being English, I shouldn’t, either!” – “There is so-called ‘idealist’ logic; if so, there is so called ‘idealist implicaturum’” “My favourite idealist philosopher is Bosanquet.” “I like Bradley because Russell was once a Bradleyian, when it was fashionable to be so! But surely Russell lacked the spirit to understand, even, Bradley! It is so much easier to mock him!” --. Refs.: H. P. Grice, “Pre-war Oxford philosophy.” The reference to mentalism in the essay on ‘modest mentalism,’ after Myro, in The H. P. Grice Papers, BANC.

oxonian or oxford aristototelian: or the Oxonian peripatos – or the Peripatos in the Oxonian lycaeum -- Cambridge Platonists: If Grice adored Aristotle, it was perhaps he hated the Cambridge platonists so! a group of seventeenth-century philosopher-theologians at the  of Cambridge, principally including Benjamin Whichcote 160983, often designated the father of the Cambridge Platonists; Henry More; Ralph Cudworth 161788; and John Smith 161652. Whichcote, Cudworth, and Smith received their  education in or were at some time fellows of Emmanuel , a stronghold of the Calvinism in which they were nurtured and against which they rebelled under mainly Erasmian, Arminian, and Neoplatonic influences. Other Cambridge men who shared their ideas and attitudes to varying degrees were Nathanael Culverwel 1618?51, Peter Sterry 161372, George Rust d.1670, John Worthington 161871, and Simon Patrick 1625 1707. As a generic label, ‘Cambridge Platonists’ is a handy umbrella term rather than a dependable signal of doctrinal unity or affiliation. The Cambridge Platonists were not a self-constituted group articled to an explicit manifesto; no two of them shared quite the same set of doctrines or values. Their Platonism was not exclusively the pristine teaching of Plato, but was formed rather from Platonic ideas supposedly prefigured in Hermes Trismegistus, in the Chaldean Oracles, and in Pythagoras, and which they found in Origen and other church fathers, in the Neoplatonism of Plotinus and Proclus, and in the Florentine Neoplatonism of Ficino. They took contrasting and changing positions on the important belief originating in Florence with Giovanni Pico della Mirandola that Pythagoras and Plato derived their wisdom ultimately from Moses and the cabala. They were not equally committed to philosophical pursuits, nor were they equally versed in the new philosophies and scientific advances of the time. The Cambridge Platonists’ concerns were ultimately religious and theological rather than primarily philosophical. They philosophized as theologians, making eclectic use of philosophical doctrines whether Platonic or not for apologetic purposes. They wanted to defend “true religion,” namely, their latitudinarian vision of Anglican Christianity, against a variety of enemies: the Calvinist doctrine of predestination; sectarianism; religious enthusiasm; fanaticism; the “hide-bound, strait-laced spirit” of Interregnum Puritanism; the “narrow, persecuting spirit” that followed the Restoration; atheism; and the impieties incipient in certain trends in contemporary science and philosophy. Notable among the latter were the doctrines of the mechanical philosophers, especially the materialism and mechanical determinism of Hobbes and the mechanistic pretensions of the Cartesians. The existence of God, the existence, immortality, and dignity of the human soul, the existence of spirit activating the natural world, human free will, and the primacy of reason are among the principal teachings of the Cambridge Platonists. They emphasized the positive role of reason in all aspects of philosophy, religion, and ethics, insisting in particular that it is irrationality that endangers the Christian life. Human reason and understanding was “the Candle of the Lord” Whichcote’s phrase, perhaps their most cherished image. In Whichcote’s words, “To go against Reason, is to go against God . . . Reason is the Divine Governor of Man’s Life; it is the very Voice of God.” Accordingly, “there is no real clashing at all betwixt any genuine point of Christianity and what true Philosophy and right Reason does determine or allow” More. Reason directs us to the self-evidence of first principles, which “must be seen in their own light, and are perceived by an inward power of nature.” Yet in keeping with the Plotinian mystical tenor of their thought, they found within the human soul the “Divine Sagacity” More’s term, which is the prime cause of human reason and therefore superior to it. Denying the Calvinist doctrine that revelation is the only source of spiritual light, they taught that the “natural light” enables us to know God and interpret the Scriptures. Cambridge Platonism was uncompromisingly innatist. Human reason has inherited immutable intellectual, moral, and religious notions, “anticipations of the soul,” which negate the claims of empiricism. The Cambridge Platonists were skeptical with regard to certain kinds of knowledge, and recognized the role of skepticism as a critical instrument in epistemology. But they were dismissive of the idea that Pyrrhonism be taken seriously in the practical affairs of the philosopher at work, and especially of the Christian soul in its quest for divine knowledge and understanding. Truth is not compromised by our inability to devise apodictic demonstrations. Indeed Whichcote passed a moral censure on those who pretend “the doubtfulness and uncertainty of reason.” Innatism and the natural light of reason shaped the Cambridge Platonists’ moral philosophy. The unchangeable and eternal ideas of good and evil in the divine mind are the exemplars of ethical axioms or noemata that enable the human mind to make moral judgments. More argued for a “boniform faculty,” a faculty higher than reason by which the soul rejoices in reason’s judgment of the good. The most philosophically committed and systematic of the group were More, Cudworth, and Culverwel. Smith, perhaps the most intellectually gifted and certainly the most promising note his dates, defended Whichcote’s Christian teaching, insisting that theology is more “a Divine Life than a Divine Science.” More exclusively theological in their leanings were Whichcote, who wrote little of solid philosophical interest, Rust, who followed Cudworth’s moral philosophy, and Sterry. Only Patrick, More, and Cudworth all fellows of the Royal Society were sufficiently attracted to the new science especially the work of Descartes to discuss it in any detail or to turn it to philosophical and theological advantage. Though often described as a Platonist, Culverwel was really a neo-Aristotelian with Platonic embellishments and, like Sterry, a Calvinist. He denied innate ideas and supported the tabula rasa doctrine, commending “the Platonists . . . that they lookt upon the spirit of a man as the Candle of the Lord, though they were deceived in the time when ‘twas lighted.” The Cambridge Platonists were influential as latitudinarians, as advocates of rational theology, as severe critics of unbridled mechanism and materialism, and as the initiators, in England, of the intuitionist ethical tradition. In the England of Locke they are a striking counterinstance of innatism and non-empirical philosophy. 

camera obscura: cited by H. P. Grice and G. J. Warnock on “Seeing” – and the Causal Theory of Seeing – “visa” -- a darkened enclosure that focuses light from an external object by a pinpoint hole instead of a lens, creating an inverted, reversed image on the opposite wall. The adoption of the camera obscura as a model for the eye revolutionized the study of visual perception by rendering obsolete previous speculative philosophical theories, in particular the emanation theory, which explained perception as due to emanated copy-images of objects entering the eye, and theories that located the image of perception in the lens rather than the retina. By shifting the location of sensation to a projection on the retina, the camera obscura doctrine helped support the distinction of primary and secondary sense qualities, undermining the medieval realist view of perception and moving toward the idea that consciousness is radically split off from the world.

oxonian dialectic, or rather Mertonian dialectic – (“You need to go to Merton to do dialectic” – Grice).- dialectic: H. P. Grice, “Athenian dialectic and Oxonian dialectic,” an argumentative exchange involving contradiction or a technique or method connected with such exchanges. The word’s origin is the Grecian dialegein, ‘to argue’ or ‘converse’; in Aristotle and others, this often has the sense ‘argue for a conclusion’, ‘establish by argument’. By Plato’s time, if not earlier, it had acquired a technical sense: a form of argumentation through question and answer. The adjective dialektikos, ‘dialectical’, would mean ‘concerned with dialegein’ or of persons ‘skilled in dialegein’; the feminine dialektike is then ‘the art of dialegein’. Aristotle says that Zeno of Elea invented diagonalization dialectic 232   232 dialectic. He apparently had in mind Zeno’s paradoxical arguments against motion and multiplicity, which Aristotle saw as dialectical because they rested on premises his adversaries conceded and deduced contradictory consequences from them. A first definition of dialectical argument might then be: ‘argument conducted by question and answer, resting on an opponent’s concessions, and aiming at refuting the opponent by deriving contradictory consequences’. This roughly fits the style of argument Socrates is shown engaging in by Plato. So construed, dialectic is primarily an art of refutation. Plato, however, came to apply ‘dialectic’ to the method by which philosophers attain knowledge of Forms. His understanding of that method appears to vary from one dialogue to another and is difficult to interpret. In Republic VIVII, dialectic is a method that somehow establishes “non-hypothetical” conclusions; in the Sophist, it is a method of discovering definitions by successive divisions of genera into their species. Aristotle’s concept of dialectical argument comes closer to Socrates and Zeno: it proceeds by question and answer, normally aims at refutation, and cannot scientifically or philosophically establish anything. Aristotle differentiates dialectical arguments from demonstration apodeixis, or scientific arguments, on the basis of their premises: demonstrations must have “true and primary” premises, dialectical arguments premises that are “apparent,” “reputable,” or “accepted” these are alternative, and disputed, renderings of the term endoxos. However, dialectical arguments must be valid, unlike eristic or sophistical arguments. The Topics, which Aristotle says is the first art of dialectic, is organized as a handbook for dialectical debates; Book VIII clearly presupposes a ruledirected, formalized style of disputation presumably practiced in the Academy. This use of ‘dialectic’ reappears in the early Middle Ages in Europe, though as Aristotle’s works became better known after the twelfth century dialectic was increasingly associated with the formalized disputations practiced in the universities recalling once again the formalized practice presupposed by Aristotle’s Topics. In his Critique of Pure Reason, Kant declared that the ancient meaning of ‘dialectic’ was ‘the logic of illusion’ and proposed a “Transcendental Dialectic” that analyzed the “antinomies” deductions of contradictory conclusions to which pure reason is inevitably led when it extends beyond its proper sphere. This concept was further developed by Fichte and Schelling into a traidic notion of thesis, opposing antithesis, and resultant synthesis. Hegel transformed the notion of contradiction from a logical to a metaphysical one, making dialectic into a theory not simply of arguments but of historical processes within the development of “spirit”; Marx transformed this still further by replacing ‘spirit’ with ‘matter’. 

oxonian Epicureanism, -- cf. Grice, “Il giardino di Epicuro a Roma.” -- Walter Pater, “Marius, The Epicurean” -- one of the three leading movements constituting Hellenistic philosophy. It was founded by Epicurus 341271 B.C., together with his close colleagues Metrodorus c.331 278, Hermarchus Epicurus’s successor as head of the Athenian school, and Polyaenus d. 278. He set up Epicurean communities at Mytilene, Lampsacus, and finally Athens 306 B.C., where his school the Garden became synonymous with Epicureanism. These groups set out to live the ideal Epicurean life, detached from political society without actively opposing it, and devoting themselves to philosophical discussion and the cult of friendship. Their correspondence was anthologized and studied as a model of the philosophical life by later Epicureans, for whom the writings of Epicurus and his three cofounders, known collectively as “the Men,” held a virtually biblical status. Epicurus wrote voluminously, but all that survives are three brief epitomes the Letter to Herodotus on physics, the Letter to Pythocles on astronomy, etc., and the Letter to Menoeceus on ethics, a group of maxims, and papyrus fragments of his magnum opus On Nature. Otherwise, we are almost entirely dependent on secondary citations, doxography, and the writings of his later followers. The Epicurean physical theory is atomistic, developed out of the fifth-century system of Democritus. Per se existents are divided into bodies and space, each of them infinite in quantity. Space is, or includes, absolute void, without which motion would be impossible, while body is constituted out of physically indivisible particles, “atoms.” Atoms are themselves further analyzable as sets of absolute “minima,” the ultimate quanta of magnitude, posited by Epicurus to circumvent the paradoxes that Zeno of Elea had derived from the hypothesis of infinite divisibility. Atoms themselves have only the primary properties of shape, size, and weight. All secondary properties, e.g. color, are generated out of atomic compounds; given their dependent status, they cannot be added to the list of per se existents, but it does not follow, as the skeptical tradition in atomism had held, that they are not real either. Atoms are in constant rapid motion, epapoge Epicureanism 269   269 at equal speed since in the pure void there is nothing to slow them down. Stability emerges as an overall property of compounds, which large groups of atoms form by settling into regular patterns of complex motion, governed by the three motive principles of weight, collisions, and a minimal random movement, the “swerve,” which initiates new patterns of motion and blocks the danger of determinism. Our world itself, like the countless other worlds, is such a compound, accidentally generated and of finite duration. There is no divine mind behind it, or behind the evolution of life and society: the gods are to be viewed as ideal beings, models of the Epicurean good life, and therefore blissfully detached from our affairs. Canonic, the Epicurean theory of knowledge, rests on the principle that “all sensations are true.” Denial of empirical cognition is argued to amount to skepticism, which is in turn rejected as a self-refuting position. Sensations are representationally not propositionally true. In the paradigm case of sight, thin films of atoms Grecian eidola, Latin simulacra constantly flood off bodies, and our eyes mechanically report those that reach them, neither embroidering nor interpreting. Inference from these guaranteed photographic, as it were data to the nature of external objects themselves involves judgment, and there alone error can occur. Sensations thus constitute one of the three “criteria of truth,” along with feelings, a criterion of values and introspective information, and prolepseis, or naturally acquired generic conceptions. On the basis of sense evidence, we are entitled to infer the nature of microscopic or remote phenomena. Celestial phenomena, e.g., cannot be regarded as divinely engineered which would conflict with the prolepsis of the gods as tranquil, and experience supplies plenty of models that would account for them naturalistically. Such grounds amount to consistency with directly observed phenomena, and are called ouk antimarturesis “lack of counterevidence”. Paradoxically, when several alternative explanations of the same phenomenon pass this test, all must be accepted: although only one of them can be true for each token phenomenon, the others, given their intrinsic possibility and the spatial and temporal infinity of the universe, must be true for tokens of the same type elsewhere. Fortunately, when it comes to the basic tenets of physics, it is held that only one theory passes this test of consistency with phenomena. Epicurean ethics is hedonistic. Pleasure is our innate natural goal, to which all other values, including virtue, are subordinated. Pain is the only evil, and there is no intermediate state. Philosophy’s task is to show how pleasure can be maximized, as follows: Bodily pleasure becomes more secure if we adopt a simple way of life that satisfies only our natural and necessary desires, with the support of like-minded friends. Bodily pain, when inevitable, can be outweighed by mental pleasure, which exceeds it because it can range over past, present, and future. The highest pleasure, whether of soul or body, is a satisfied state, “katastematic pleasure.” The pleasures of stimulation “kinetic pleasures”, including those resulting from luxuries, can vary this state, but have no incremental value: striving to accumulate them does not increase overall pleasure, but does increase our vulnerability to fortune. Our primary aim should instead be to minimize pain. This is achieved for the body through a simple way of life, and for the soul through the study of physics, which achieves the ultimate katastematic pleasure, ”freedom from disturbance” ataraxia, by eliminating the two main sources of human anguish, the fears of the gods and of death. It teaches us a that cosmic phenomena do not convey divine threats, b that death is mere disintegration of the soul, with hell an illusion. To fear our own future non-existence is as irrational as to regret the non-existence we enjoyed before we were born. Physics also teaches us how to evade determinism, which would turn moral agents into mindless fatalists: the swerve doctrine secures indeterminism, as does the logical doctrine that future-tensed propositions may be neither true nor false. The Epicureans were the first explicit defenders of free will, although we lack the details of their positive explanation of it. Finally, although Epicurean groups sought to opt out of public life, they took a keen and respectful interest in civic justice, which they analyzed not as an absolute value, but as a contract between humans to refrain from harmful activity on grounds of utility, perpetually subject to revision in the light of changing circumstances. Epicureanism enjoyed widespread popularity, but unlike its great rival Stoicism it never entered the intellectual bloodstream of the ancient world. Its stances were dismissed by many as philistine, especially its rejection of all cultural activities not geared to the Epicurean good life. It was also increasingly viewed as atheistic, and its ascetic hedonism was misrepresented as crude sensualism hence the modern use of ‘epicure’. The school nevertheless continued to flourish down to and well beyond the end of the Hellenistic age. In the first century B.C. its exponents Epicureanism Epicureanism 270   270 included Philodemus, whose fragmentarily surviving treatise On Signs attests to sophisticated debates on induction between Stoics and Epicureans, and Lucretius, the Roman author of the great Epicurean didactic poem On the Nature of Things. In the second century A.D. another Epicurean, Diogenes of Oenoanda, had his philosophical writings engraved on stone in a public colonnade, and passages have survived. Thereafter Epicureanism’s prominence declined. Serious interest in it was revived by Renaissance humanists, and its atomism was an important influence on early modern physics, especially through Gassendi.  Refs.: Luigi Speranza, “Grice e il giardino di Epicuro a Roma,” per il Club Anglo-Italiano, The Swimming-Pool Library, Villa Grice, Liguria, Italia.

oxonianism: Grice was “university lecturer in philosophy” and “tutorial fellow in philosophy” – that’s why he always saw philosophy, like virtue, as entire. He would never accept a post like “professor of moral philosophy” or “professor of logic,” or “professor of metaphysical philosophy,” or “reader in natural theology,” or “reader in mental philosophy.” So he felt a responsibility towards ‘philosophy undepartmentilised’ and he succeded in never disgressing from this gentlemanly attitude to philosophy as a totum, and not a technically specified field of ‘expertise.’ See playgroup. The playgroup was Oxonian. There are aspects of Grice’s philosophy which are Oxonian but not playgroup-related, and had to do with his personal inclinations. The fact that it was Hardie who was his tutor and instilled on him a love for Aristotle. Grice’s rapport with H. A. Prichard. Grice would often socialize with members of Ryle’s group, such as O. P. Wood, J. D. Mabbott, and W. C. Kneale. And of course, he had a knowleddge of the history of Oxford philosophy, quoting from J. C. Wilson, G. F. Stout, H. H. Price, Bosanquet, Bradley. He even had his Oxonian ‘enemies,’ Dummett, Anscombe. And he would quote from independents, like A. J. P. Kenny. But if he had to quote someone first, it was a member of his beloved playgroup: Austin, Strawson, Warnock, Urmson, Hare, Hart, Hampshire. Grice cannot possibly claim to talk about post-war Oxford philosophy, but his own! Cf. Oxfords post-war philosophy.  What were Grices first impressions when arriving at Oxford. He was going to learn. Only the poor learn at Oxford was an adage he treasured, since he wasnt one! Let us start with an alphabetical listing of Grices play Group companions: Austin, Butler, Flew, Gardiner, Grice, Hare, Hampshire, Hart, Nowell-Smith, Parkinson, Paul, Pears, Quinton, Sibley, Strawson, Thomson, Urmson, and Warnock.  Grices main Oxonian association is St. Johns, Oxford. By Oxford Philosophy, Grice notably refers to Austins Play Group, of which he was a member. But Grice had Oxford associations pre-war, and after the demise of Austin. But back to the Play Group, this, to some, infamous, playgroup, met on Saturday mornings at different venues at Oxford, including Grices own St. John’s ‒ apparently, Austins favourite venue. Austin regarded himself and his kindergarten as linguistic or language botanists. The idea was to list various ordinary uses of this or that philosophical notion. Austin: They say philosophy is about language; well, then, let’s botanise! Grices involvement with Oxford philosophy of course predated his associations with Austins play group. He always said he was fortunate of having been a tutee to Hardie at Corpus. Corpus, Oxford. Grice would occasionally refer to the emblematic pelican, so prominently displayed at Corpus. Grice had an interim association with the venue one associates most directly with philosophy, Merton ‒: Grice, Merton, Oxford. While Grice loved to drop Oxonian Namess, notably his rivals, such as Dummett or Anscombe, he knew when not to. His Post-war Oxford philosophy, as opposed to more specific items in The Grice Collection, remains general in tone, and intended as a defense of the ordinary-language approach to philosophy. Surprisingly, or perhaps not (for those who knew Grice), he takes a pretty idiosyncratic characterisation of conceptual analysis. Grices philosophical problems emerge with Grices idiosyncratic use of this or that expression. Conceptual analysis is meant to solve his problems, not others, repr. in WOW . Grice finds it important to reprint this since he had updated thoughts on the matter, which he displays in his Conceptual analysis and the province of philosophy. The topic represents one of the strands he identifies behind the unity of his philosophy. By post-war Oxford philosophy, Grice meant the period he was interested in. While he had been at Corpus, Merton, and St. Johns in the pre-war days, for some reason, he felt that he had made history in the post-war period. The historical reason Grice gives is understandable enough. In the pre-war days, Grice was the good student and the new fellow of St. Johns ‒ the other one was Mabbott. But he had not been able to engage in philosophical discussion much, other than with other tutees of Hardie. After the war, Grice indeed joins Austins more popular, less secretive Saturday mornings. Indeed, for Grice, post-war means all philosophy after the war (and not just say, the forties!) since he never abandoned the methods he developed under Austin, which were pretty congenial to the ones he had himself displayed in the pre-war days, in essays like Negation and Personal identity. Grice is a bit of an expert on Oxonian philosophy. He sees himself as a member of the school of analytic philosophy, rather than the abused term ordinary-language philosophy. This is evident by the fact that he contributed to such polemic  ‒ but typically Oxonian  ‒ volumes such as Butler, Analytic Philosophy, published by Blackwell (of all publishers). Grice led a very social life at Oxford, and held frequent philosophical discussions with the Play group philosophers (alphabetically listed above), and many others, such as Wood.  Post-war Oxford philosophy, miscellaneous, Oxford philosophy, in WOW, II, Semantics and Met. , Essay. By Oxford philosophy, Grice means his own. Grice went back to the topic of philosophy and ordinary language, as one of his essays is precisely entitled, Philosophy and ordinary language, philosophy and ordinary language, : ordinary-language philosophy, linguistic botanising. Grice is not really interested in ordinary language as a philologist might. He spoke ordinary language, he thought. The point had been brought to the fore by Austin. If they think philosophy is a play on words, well then, lets play the game. Grices interest is methodological. Malcolm had been claiming that ordinary language is incorrigible. While Grice agreed that language can be clever, he knew that Aristotle was possibly right when he explored ta legomena in terms of the many and the selected wise, philosophy and ordinary language, philosophy and ordinary language, : philosophy, ordinary language. At the time of writing, ordinary-language philosophy had become, even within Oxford, a bit of a term of abuse. Grice tries to defend Austins approach to it, while suggesting ideas that Austin somewhat ignored, like what an utterer implies by the use of an ordinary-language expression, rather than what the expression itself does. Grice is concerned, contra Austin, in explanation (or explanatory adequacy), not taxonomy (or descriptive adequacy). Grice disregards Austins piecemeal approach to ordinary language, as Grice searches for the big picture of it all. Grice never used ordinary language seriously. The phrase was used, as he explains, by those who HATED ordinary-language philosophy. Theres no such thing as ordinary language. Surely you cannot fairly describe the idiosyncratic linguistic habits of an Old Cliftonian as even remotely ordinary. Extra-ordinary more likely! As far as the philosophy bit goes, this is what Bergmann jocularly described as the linguistic turn. But as Grice notes, the linguistic turn involves both the ideal language and the ordinary language. Grice defends the choice by Austin of the ordinary seeing that it was what he had to hand! While Grice seems to be in agreement with the tone of his Wellesley talk, his idioms there in. Youre crying for the moon! Philosophy need not be grand! These seem to contrast with his more grandiose approach to philosophy. His struggle was to defend the minutiæ of linguistic botanising, that had occupied most of his professional life, with a grander view of the discipline. He blamed Oxford for that. Never in the history of philosophy had philosophers shown such an attachment to ordinary language as they did in post-war Oxford, Grice liked to say.  Having learned Grecian and Latin at Clifton, Grice saw in Oxford a way to go back to English! He never felt the need to explore Continental modern languages like German or French. Aristotle was of course cited in Greek, but Descartes is almost not cited, and Kant is cited in the translation available to Oxonians then. Grice is totally right that never has philosophy experienced such a fascination with ordinary use except at Oxford. The ruthless and unswerving association of philosophy with ordinary language has been peculiar to the Oxford scene. While many found this attachment to ordinary usage insidious, as Warnock put it, it fit me and Grice to a T, implicating you need a sort of innate disposition towards it! Strawson perhaps never had it! And thats why Grices arguments contra Strawson rest on further minutiæ whose detection by Grice never ceased to amaze his tutee! In this way, Grice felt he WAS Austins heir! While Grice is associated with, in chronological order, Corpus, Merton, and St. Johns, it is only St. Johns that counts for the Griceian! For it is at St. Johns he was a Tutorial Fellow in Philosophy! And we love him as a philosopher. Refs.: The obvious keyword is “Oxford.” His essay in WoW on post-war Oxford philosophy is general – the material in the H. P. Grice papers is more anecdotic.

pacifism: Grice fought in the second world war with the Royal Navy and earned the rank of captain. 1 opposition to war, usually on moral or religious grounds, but sometimes on the practical ground pragmatic pacifism that it is wasteful and ineffective; 2 opposition to all killing and violence; 3 opposition only to war of a specified kind e.g., nuclear pacifism. Not to be confused with passivism, pacifism usually involves actively promoting peace, understood to imply cooperation and justice among peoples and not merely absence of war. But some usually religious pacifists accept military service so long as they do not carry weapons. Many pacifists subscribe to nonviolence. But some consider violence and/or killing permissible, say, in personal self-defense, law enforcement, abortion, or euthanasia. Absolute pacifism rejects war in all circumstances, hypothetical and actual. Conditional pacifism concedes war’s permissibility in some hypothetical circumstances but maintains its wrongness in practice. If at least some hypothetical wars have better consequences than their alternative, absolute pacifism will almost inevitably be deontological in character, holding war intrinsically wrong or unexceptionably prohibited by moral principle or divine commandment. Conditional pacifism may be held on either deontological or utilitarian teleological or sometimes consequentialist grounds. If deontological, it may hold war at most prima facie wrong intrinsically but nonetheless virtually always impermissible in practice because of the absence of counterbalancing right-making features. If utilitarian, it will hold war wrong, not intrinsically, but solely because of its consequences. It may say either that every particular war has worse consequences than its avoidance act utilitarianism or that general acceptance of or following or compliance with a rule prohibiting war will have best consequences even if occasional particular wars have best consequences rule utilitarianism.

paine: philosopher, revolutionary defender of democracy and human rights, and champion of popular radicalism in three countries. Born in Thetford, England, he emigrated to the  colonies in 1774 (but was never accepted by the descendants of the Mayfower), and moved to France, where he was made a  proper French citizen in 1792. In 1802 he returned to the United States (as that section of the New World was then called), where he was rebuffed by the public because of his support for the  Revolution. Paine was the bestknown polemicist for the  Revolution. In many incendiary pamphlets, he called for a new, more democratic republicanism. His direct style and uncompromising egalitarianism had wide popular appeal. In Common Sense 1776 Paine asserted that commoners were the equal of the landed aristocracy, thus helping to spur colonial resentments sufficiently to support independence from Britain. The sole basis of political legitimacy is universal, active consent; taxation without representation is unjust; and people have the right to resist when the contract between governor and governed is broken. He defended the  Revolution in The Rights of Man 179, arguing against concentrating power in any one individual and against a property qualification for suffrage. Since natural law and right reason as conformity to nature are accessible to all rational persons, sovereignty resides in human beings and is not bestowed by membership in class or nation. Opposed to the extremist Jacobins, he helped write, with Condorcet, a constitution to secure the Revolution. The Age of Reason 1794, Paine’s most misunderstood work, sought to secure the social cohesion necessary to a well-ordered society by grounding it in belief in a divinity. But in supporting deism and attacking established religion as a tool of enslavement, he alienated the very laboring classes he sought to enlighten. A lifelong adversary of slavery and supporter of universal male suffrage, Paine argued for redistributing property in Agrarian Justice 1797. 

palæo-Griceian: Within the Oxford group, Grice was the first, and it’s difficult to find a precursor. It’s obviously Grice was not motivated to create or design his manoeuvre to oppose a view by Ryle – who cared about Ryle in the playgroup? None – It is obviously more clear that Grice cared a hoot about Vitters, Benjamin, and Malcolm. So that leaves us with the philosophers Grice personally knew. And we are sure he was more interested in criticizing Austin than his own tutee Strawson. So ths leaves us with Austin. Grice’s manoeuvre was intended for Austin – but he waited for Austin’s demise to present it. Even though the sources were publications that were out there before Austin died (“Other minds,” “A plea for excuses”). So Grice is saying that Austin is wrong, as he is. In order of seniority, the next was Hart (who Grice mocked about ‘carefully’ in Prolegomena. Then came more or less same-generational Hare (who was not too friendly with Grice) and ‘to say ‘x is good’ is to recommend x’ (a ‘performatory fallacy’) and Strawson with ‘true’ and, say, ‘if.’ So, back to the palaeo-Griceian, surely nobody was in a position to feel a motivation to criticise Austin, Hart, Hare, and Strawson! When philosophers mention this or that palaeo-Griceian philosopher, surely the motivation was different. And a philosophical manoevre COMES with a motivation. If we identify some previous (even Oxonian) philosopher who was into the thing Grice is, it would not have Austin, Hart, Hare or Strawson as ‘opponents.’ And of course it’s worse with post-Griceians. Because, as Grice says, there was no othe time than post-war Oxford philosophy where “my manoeuvre would have make sense.’ If it does, as it may, post-Grice, it’s “as derivative” of “the type of thing we were doing back in the day. And it’s no fun anymore.” “Neo-Griceian” is possibly a misnomer. As Grice notes, “usually you add ‘neo-’ to sell; that’s why, jokingly, I call Strawson a neo-traditionalist; as if he were a bit of a neo-con, another oxymoron, as he was!’That is H. P. Grice was the first member of the play group to come up with a system of ‘pragmatic rules.’ Or perhaps he wasn’t. In any case, palaeo-Griceian refers to any attempt by someone who is an Oxonian English philosopher who suggested something like H. P. Grice later did! There are palaeo-Griceian suggestions in Bradley – “Logic” --, Bosanquet, J. C. Wilson (“Statement and inference”) and a few others. Within those who interacted with Grice to provoke him into the ‘pragmatic rule’ account were two members of the play group. One was not English, but a Scot: G. A. Paul. Paul had been to ‘the other place,’ and was at Oxford trying to spread Witters’s doctrine. The bafflement one gets from “I certainly don’t wish to cast any doubt on the matter, but that pillar box seems red to me; and the reason why it is does, it’s because it is red, and its redness causes in my sense of vision the sense-datum that the thing is red.” Grice admits that he first came out with the idea when confronted with this example. Mainly Grice’s motivation is to hold that such a ‘statement’ (if statement, it is, -- vide Bar-Hillel) is true. The other member was English: P. F. Strawson. And Grice notes that it was Strawson’s Introduction to logical theory that motivated him to apply a technique which had proved successful in the area of the philosophy of perception to this idea by Strawson that Whitehead and Russell are ‘incorrect.’ Again, Grice’s treatment concerns holding a ‘statement’ to be ‘true.’ Besides these two primary cases, there are others. First, is the list of theses in “Causal Theory.” None of them are assigned to a particular philosopher, so the research may be conducted towards the identification of these. The theses are, besides the one he is himself dealing, the sense-datum ‘doubt or denial’ implicaturum: One, What is actual is not also possible. Two, What is known to be the case is not also believed to be the case. Three, Moore was guilty of misusing the lexeme ‘know.’ Four, To say that someone is responsible is to say that he is accountable for something condemnable. Six, A horse cannot look like a horse. Now, in “Prolegomena” he add further cases. Again, since this are palaeo-Griceian, it may be a matter of tracing the earliest occurrences. In “Prolegomena,” Grice divides the examples in Three Groups. The last is an easy one to identity: the ‘performatory’ approach: for which he gives the example by Strawson on ‘true,’ and mentions two other cases: a performatory use of ‘I know’ for I guarantee; and the performatory use of ‘good’ for ‘I approve’ (Ogden). The second group is easy to identify since it’s a central concern and it is exactly Strawson’s attack on Whitehead and Russell. But Grice is clear here. It is mainly with regard to ‘if’ that he wants to discuss Strawson, and for which he quotes him at large. Before talking about ‘if’, he mentions the co-ordinating connectives ‘and’ and ‘or’, without giving a source. So, here there is a lot to research about the thesis as held by other philosophers even at Oxford (where, however, ‘logic’ was never considered a part of philosophy proper). The first group is the most varied, and easier to generalise, because it refers to any ‘sub-expression’ held to occur in a full expression which is held to be ‘inappropriate.’ Those who judge the utterance to be inappropriate are sometimes named. Grice starts with Ryle and The Concept of Mind – palaeo-Griceian, in that it surely belongs to Grice’s previous generation. It concerns the use of the adverb ‘voluntary’ and Grice is careful to cite Ryle’s description of the case, using words like ‘incorrect,’ and that a ‘sense’ claimed by philosophers is an absurd one. Then there is a third member of the playgroup – other than G. A. Paul and P. F. Strawson – the Master Who Wobbles, J. L. Austin. Grice likes the way Austin offers himself as a good target – Austin was dead by then, and Grice would otherwise not have even tried – Austin uses variables: notably Mly, and a general thesis, ‘no modification without aberration.’ But basically, Grice agrees that it’s all about the ‘philosophy of action.’ So in describing an agent’s action, the addition of an adverb makes the whole thing inappropriate. This may relate to at least one example in “Causal” involving ‘responsible.’ While Grice there used the noun and adjective, surely it can be turned into an adverb. The fourth member of the playgroup comes next: H. L. A. Hart. Grice laughs at Hart’s idea that to add ‘carefully’ in the description of an action the utterer is committed to the idea that the agent THINKS the steps taken for the performance are reasonable. There is a thesis he mentions then which alla “Causal Theory,” gets uncredited – about ‘trying.’ But he does suggest Witters. And then there is his own ‘doubt or denial’ re: G. A. Paul, and another one in the field of the philosophy of perception that he had already mentioned vaguely in “Causal”: a horse cannot look like a horse. Here he quotes Witters in extenso, re: ‘seeing as.’ While Grice mentions ‘philosophy of action,’ there is at least one example involving ‘philosophical psychology’: B. S. Benjamin on C. D. Broad on the factiveness of ‘remember.’ When one thinks of all the applications that the ‘conversational model’ has endured, one realizes that unless your background is philosophical, you are bound not to realise the centrality of Grice’s thesis for philosophical methodology.

palæo-Kantian: Kantian, neo-Kantian. Cohen, Hermann – Grice liked to think of himself as a neo-Kantian (“rather than a palaeo-Kantian, you see”) --  philosopher who originated and led, with Paul Natorp, the Marburg School of neo-Kantianism. He taught at Marburg. Cohen wrote commentaries on Kant’s Critiques prior to publishing System der Philosophie 212, which consisted of parts on logic, ethics, and aesthetics. He developed a Kantian idealism of the natural sciences, arguing that a transcendental analysis of these sciences shows that “pure thought” his system of Kantian a priori principles “constructs” their “reality.” He also developed Kant’s ethics as a democratic socialist ethics. He ended his career at a rabbinical seminary in Berlin, writing his influential Religion der Vernunft aus den Quellen des Judentums “Religion of Reason out of the Sources of Judaism,” 9, which explicated Judaism on the basis of his own Kantian ethical idealism. Cohen’s ethical-political views were adopted by Kurt Eisner 18679, leader of the Munich revolution of 8, and also had an impact on the revisionism of orthodox Marxism of the G. Social Democratic Party, while his philosophical writings greatly influenced Cassirer. 

paley: English moral philosopher and theologian. He was born in Peterborough and educated at Cambridge, where he lectured in moral philosophy, divinity, and Grecian New Testament before assuming a series of posts in the C. of E., the last as archdeacon of Carlisle. The Principles of Moral and Political Philosophy first introduced utilitarianism to a wide public. Moral obligation is created by a divine command “coupled” with the expectation of everlasting rewards or punishments. While God’s commands can be ascertained “from Scripture and the light of nature,” Paley emphasizes the latter. Since God wills human welfare, the rightness or wrongness of actions is determined by their “tendency to promote or diminish the general happiness.” Horae Pauline: Or the Truth of the Scripture History of St Paul Evinced appeared in 1790, A View of the Evidences of Christianity in 1794. The latter defends the authenticity of the Christian miracles against Hume. Natural Theology 1802 provides a design argument for God’s existence and a demonstration of his attributes. Nature exhibits abundant contrivances whose “several parts are framed and put together for a purpose.” These contrivances establish the existence of a powerful, wise, benevolent designer. They cannot show that its power and wisdom are unlimited, however, and “omnipotence” and “omniscience” are mere “superlatives.” Paley’s Principles and Evidences served as textbooks in England and America well into the nineteenth century. 

panpsychism, the doctrine that the physical world is pervasively psychical, sentient or conscious understood as equivalent. The idea, usually, is that it is articulated into certain ultimate units or particles, momentary or enduring, each with its own distinct charge of sentience or consciousness, and that some more complex physical units possess a sentience emergent from the interaction between the charges of sentience pertaining to their parts, sometimes down through a series of levels of articulation into sentient units. Animal consciousness is the overall sentience pertaining to some substantial part or aspect of the brain, while each neuron may have its own individual charge of sentience, as may each included atom and subatomic particle. Elsewhere the only sentient units may be at the atomic and subatomic level. Two differently motivated versions of the doctrine should be distinguished. The first implies no particular view about the nature of matter, and regards the sentience pertaining to each unit as an extra to its physical nature. Its point is to explain animal and human consciousness as emerging from the interaction and perhaps fusion of more pervasive sentient units. The better motivated, second version holds that the inner essence of matter is unknown. We know only structural facts about the physical or facts about its effects on sentience like our own. Panpsychists hypothesize that the otherwise unknown inner essence of matter consists in sentience or consciousness articulated into the units we identify externally as fundamental particles, or as a supervening character pertaining to complexes of such or complexes of complexes, etc. Panpsychists can thus uniquely combine the idealist claim that there can be no reality without consciousness with rejection of any subjectivist reduction of the physical world to human experience of it. Modern versions of panpsychism e.g. of Whitehead, Hartshorne, and Sprigge are only partly akin to hylozoism as it occurred in ancient thought. Note that neither version need claim that every physical object possesses consciousness; no one supposes that a team of conscious cricketers must itself be conscious. 

pantheism, the view that God is identical with everything. It may be seen as the result of two tendencies: an intense religious spirit and the belief that all reality is in some way united. Pantheism should be distinguished from panentheism, the view that God is in all things. Just as water might saturate a sponge and in that way be in the entire sponge, but not be identical with the sponge, God might be in everything without being identical with everything. Spinoza is the most distinguished pantheist in Western philosophy. He argued that since substance is completely self-sufficient, and only God is self-sufficient, God is the only substance. In other words, God is everything. Hegel is also sometimes considered a pantheist since he identifies God with the totality of being. Many people think that pantheism is tantamount to atheism, because they believe that theism requires that God transcend ordinary, sensible reality at least to some degree. It is not obvious that theism requires a transcendent or Panaetius pantheism 640    640 personal notion of God; and one might claim that the belief that it does is the result of an anthropomorphic view of God. In Eastern philosophy, especially the Vedic tradition of  philosophy, pantheism is part of a rejection of polytheism. The apparent multiplicity of reality is illusion. What is ultimately real or divine is Brahman.  pantheismusstreit: a debate primarily between Jacobi and Mendelssohn, although it also included Lessing, Kant, and Goethe. The basic issue concerned what pantheism is and whether every pantheists is an atheist. In particular, it concerned whether Spinoza was a pantheist, and if so, whether he was an atheist; and how close Lessing’s thought was to Spinoza’s. The standard view, propounded by Bayle and Leibniz, was that Spinoza’s pantheism was a thin veil for his atheism. Lessing and Goethe did not accept this harsh interpretation of him. They believed that his pantheism avoided the alienating transcendence of the standard Judeo-Christian concept of God. It was debated whether Lessing was a Spinozist or some form of theistic pantheist. Lessing was critical of dogmatic religions and denied that there was any revelation given to all people for rational acceptance. He may have told Jacobi that he was a Spinozist; but he may also have been speaking ironically or hypothetically. 

paracelsus, pseudonym of Theophrastus Bombastus von Hohenheim, philosopher. He pursued medical studies at various G. and Austrian universities, probably completing them at Ferrara. Thereafter he had little to do with the academic world, apart from a brief and stormy period as professor of medicine at Basle 152728. Instead, he worked first as a military surgeon and later as an itinerant physician in G.y, Austria, and Switzerland. His works were mainly in G. rather than Latin, and only a few were published during his lifetime. His importance for medical practice lay in his insistence on observation and experiment, and his use of chemical methods for preparing drugs. The success of Paracelsian medicine and chemistry in the later sixteenth and seventeenth centuries was, however, largely due to the theoretical background he provided. He firmly rejected the classical medical inheritance, particularly Galen’s explanation of disease as an imbalance of humors; he drew on a combination of biblical sources, G. mysticism, alchemy, and Neoplatonic magic as found in Ficino to present a unified view of humankind and the universe. He saw man as a microcosm, reflecting the nature of the divine world through his immortal soul, the sidereal world through his astral body or vital principle, and the terrestrial world through his visible body. Knowledge requires union with the object, but because elements of all the worlds are found in man, he can acquire knowledge of the universe and of God, as partially revealed in nature. The physician needs knowledge of vital principles called astra in order to heal. Disease is caused by external agents that can affect the human vital principle as well as the visible body. Chemical methods are employed to isolate the appropriate vital principles in minerals and herbs, and these are used as antidotes. Paracelsus further held that matter contains three principles, sulfur, mercury, and salt. As a result, he thought it was possible to transform one metal into another by varying the proportions of the fundamental principles; and that such transformations could also be used in the production of drugs. 

para-consistency: cf. paralogism -- the property of a logic in which one cannot derive all statements from a contradiction. What is objectionable about contradictions, from the standpoint of classical logic, is not just that they are false but that they imply any statement whatsoever: one who accepts a contradiction is thereby committed to accepting everything. In paraconsistent logics, however, such as relevance logics, contradictions are isolated inferentially and thus rendered relatively harmless. The interest in such logics stems from the fact that people sometimes continue to work in inconsistent theories even after the inconsistency has been exposed, and do so without inferring everything. Whether this phenomenon can be explained satisfactorily by the classical logician or shows instead that the underlying logic of, e.g., science and mathematics is some non-classical paraconsistent logic, is disputed. Refs.: H. P. Grice: “Implicatura as para-semantic.”

para-philosophy – used by Austin, borrowed (but never returned) by Grice.

para-semantic -- before vowels, par-, word-forming element, originally in Greek-derived words, meaning "alongside, beyond; altered; contrary; irregular, abnormal," from Greek para- from para (prep.) "beside, near; issuing from; against, contrary to," from PIE *prea, from root *per- (1) "forward," hence "toward, near; against." Cognate with Old English for- "off, away." Mostly used in scientific and technical words; not usually regarded as a naturalized formative element in English.

paradigm-case argument: Grice tries to give the general form of this argument, as applied to Urmson, and Grice and Strawson. I wonder if Grice thought that STRAWSON’s appeal to resentment to prove freewill is paradigm case? The idiom was coined by Grice’s first tutee at St. John’s, G. N. A. Flew, and he applied it to ‘free will.’ Grice later used it to describe the philosophising by Urmson (in “Retrospetive”). he issue of analyticity is, as Locke puts it, the issue of whats trifle. That a triangle is trilateral Locke considers a trifling proposition, like Saffron is yellow. Lewes (who calls mathematical propositions analytic) describes the Kantian problem. The reductive analysis of meaning Grice offers depends on the analytic. Few Oxonian philosophers would follow Loar, D. Phil Oxon, under Warnock, in thinking of Grices conversational maxims as empirical inductive generalisations over functional states! Synthesis may do in the New World,but hardly in the Old! The locus classicus for the ordinary-language philosophical response to Quine in Two dogmas of empiricism. Grice and Strawson claim that is analytic does have an ordinary-language use, as attached two a type of behavioural conversational response. To an analytically false move (such as My neighbours three-year-old son is an adult) the addressee A is bound to utter, I dont understand you! You are not being figurative, are you? To a synthetically false move, on the other hand (such as My neighbours three-year-old understands Russells Theory of Types), the addressee A will jump with, Cant believe it! The topdogma of analyticity is for Grice very important to defend. Philosophy depends on it! He knows that to many his claim to fame is his In defence of a dogma, the topdogma of analyticity, no less. He eventually turns to a pragmatist justification of the distinction. This pragmatist justification is still in accordance with what he sees as the use of analytic in ordinary language. His infamous examples are as follows. My neighbours three-year old understands Russells Theory of Types. A: Hard to believe, but I will. My neighbours three-year old is an adult. Metaphorically? No. Then I dont understand you, and what youve just said is, in my scheme of things, analytically false. Ultimately, there are conversational criteria, based on this or that principle of conversational helfpulness. Grice is also circumstantially concerned with the synthetic a priori, and he would ask his childrens playmates: Can a sweater be red and green all over? No stripes allowed! The distinction is ultimately Kantian, but it had brought to the fore by the linguistic turn, Oxonian and other! In defence of a dogma, Two dogmas of empiricism, : the analytic-synthetic distinction. For Quine, there are two. Grice is mainly interested in the first one: that there is a distinction between the analytic and the synthetic. Grice considers Empiricism as a monster on his way to the Rationalist City of Eternal Truth. Grice came back time and again to explore the analytic-synthetic distinction. But his philosophy remained constant. His sympathy is for the practicality of it, its rationale. He sees it as involving formal calculi, rather than his own theory of conversation as rational co-operation which does not presuppose the analytic-synthetic distinction, even if it explains it! Grice would press the issue here: if one wants to prove that such a theory of conversation as rational co-operation has to be seen as philosophical, rather than some other way, some idea of analyticity may be needed to justify the philosophical enterprise. Cf. the synthetic a priori, that fascinated Grice most than anything Kantian else! Can a sweater be green and red all over? No stripes allowed. With In defence of a dogma, Grice and Strawson attack a New-World philosopher. Grice had previously collaborated with Strawson in an essay on Met.  (actually a three-part piece, with Pears as the third author). The example Grice chooses to refute attack by Quine of the top-dogma is the Aristotelian idea of the peritrope, as Aristotle refutes Antiphasis in Met.  (v. Ackrill, Burnyeat and Dancy). Grice explores chapter Γ 8 of Aristotles Met. .  In Γ 8, Aristotle presents two self-refutation arguments against two theses, and calls the asserter, Antiphasis, T1 = Everything is true, and T2 = Everything is false, Metaph. Γ 8, 1012b13–18. Each thesis is exposed to the stock objection that it eliminates itself. An utterer who explicitly conveys that everything is true also makes the thesis opposite to his own true, so that his own is not true (for the opposite thesis denies that his is true), and any utterer U who explicitly conveys that everything is false also belies himself.  Aristotle does not seem to be claiming that, if everything is true, it would also be true that it is false that everything is true and, that, therefore, Everything is true must be false: the final, crucial inference, from the premise if, p, ~p to the conclusion ~p is missing. But it is this extra inference that seems required to have a formal refutation of Antiphasiss T1 or T2 by consequentia mirabilis. The nature of the argument as a purely dialectical silencer of Antiphasis is confirmed by the case of T2, Everything is false. An utterer who explicitly conveys that everything is false unwittingly concedes, by self-application, that what he is saying must be false too. Again, the further and different conclusion Therefore; it is false that everything is false is missing. That proposal is thus self-defeating, self-contradictory (and comparable to Grices addressee using adult to apply to three-year old, without producing the creature), oxymoronic, and suicidal. This seems all that Aristotle is interested in establishing through the self-refutation stock objection. This is not to suggest that Aristotle did not believe that Everything is true or Everything is false is false, or that he excludes that he can prove its falsehood. Grice notes that this is not what Aristotle seems to be purporting to establish in 1012b13–18. This holds for a περιτροπή (peritrope) argument, but not for a περιγραφή (perigraphe) argument (συμβαίνει δὴ καὶ τὸ θρυλούμενον πᾶσι τοῖς τοιούτοις λόγοις, αὐτοὺς ἑαυτοὺς ἀναιρεῖν. ὁ μὲν γὰρ πάντα ἀληθῆ λέγων καὶ τὸν ἐναντίον αὑτοῦ λόγον ἀληθῆ ποιεῖ, ὥστε τὸν ἑαυτοῦ οὐκ ἀληθῆ (ὁ γὰρ ἐναντίος οὔ φησιν αὐτὸν ἀληθῆ), ὁ δὲ πάντα ψευδῆ καὶ αὐτὸς αὑτόν.) It may be emphasized that Aristotles argument does not contain an explicit application of consequentia mirabilis. Indeed, no extant self-refutation argument before Augustine, Grice is told by Mates, contains an explicit application of consequentia mirabilis. This observation is a good and important one, but Grice has doubts about the consequences one may draw from it. One may take the absence of an explicit application of consequentia mirabilis to be a sign of the purely dialectical nature of the self-refutation argument. This is questionable. The formulation of a self-refutation argument (as in Grices addressee, Sorry, I misused adult.) is often compressed and elliptical and involves this or that implicaturum. One usually assumes that this or that piece in a dialectical context has been omitted and should be supplied (or worked out, as Grice prefers) by the addressee. But in this or that case, it is equally possible to supply some other, non-dialectical piece of reasoning. In Aristotles arguments from Γ 8, e.g., the addressee may supply an inference to the effect that the thesis which has been shown to be self-refuting is not true. For if Aristotle takes the argument to establish that the thesis has its own contradictory version as a consequence, it must be obvious to Aristotle that the thesis is not true (since every consequence of a true thesis is true, and two contradictory theses cannot be simultaneously true). On the further assumption (that Grice makes explicit) that the principle of bivalence is applicable, Aristotle may even infer that the thesis is false. It is perfectly plausible to attribute such an inference to Aristotle and to supply it in his argument from Γ 8. On this account, there is no reason to think that the argument is of an intrinsically dialectical nature and cannot be adequately represented as a non-dialectical proof of the non-truth, or even falsity, of the thesis in question. It is indeed difficult to see signs of a dialectical exchange between two parties (of the type of which Grice and Strawson are champions) in Γ8, 1012b13–18. One piece of evidence is Aristotles reference to the person, the utterer, as Grice prefers who explicitly conveys or asserts (ὁ λέγων) that T1 or that T2. This reference by the Grecian philosopher to the Griceian utterer or asserter of the thesis that everything is true would be irrelevant if Aristotles aim is to prove something about T1s or T2s propositional content, independently of the act by the utterer of uttering its expression and thereby explicitly conveying it. However, it is not clear that this reference is essential to Aristotles argument. One may even doubt whether the Grecian philosopher is being that Griceian, and actually referring to the asserter of T1 or T2. The *implicit* (or implicated) grammatical Subjects of Aristotles ὁ λέγων (1012b15) might be λόγος, instead of the utterer qua asserter. λόγος is surely the implicit grammatical Subjects of ὁ λέγων shortly after ( 1012b21–22. 8). The passage may be taken to be concerned with λόγοι ‒ this or that statement, this or that thesis  ‒ but not with its asserter.  In the Prior Analytics, Aristotle states that no thesis (A three-year old is an adult) can necessarily imply its own contradictory (A three-year old is not an adult) (2.4, 57b13–14). One may appeal to this statement in order to argue for Aristotles claim that a self-refutation argument should NOT be analyzed as involving an implicit application of consequentia mirabilis. Thus, one should deny that Aristotles self-refutation argument establishes a necessary implication from the self-refuting thesis to its contradictory. However, this does not explain what other kind of consequence relation Aristotle takes the self-refutation argument to establish between the self-refuting thesis and its contradictory, although dialectical necessity has been suggested. Aristotles argument suffices to establish that Everything is false is either false or liar-paradoxical. If a thesis is liar-paradoxical (and Grice loved, and overused the expression), the assumption of its falsity leads to contradiction as well as the assumption of its truth. But Everything is false is only liar-paradoxical in the unlikely, for Aristotle perhaps impossible, event that everything distinct from this thesis is false. So, given the additional premise that there is at least one true item distinct from the thesis Everything is false, Aristotle can safely infer that the thesis is false. As for Aristotles ὁ γὰρ λέγων τὸν ἀληθῆ λόγον ἀληθῆ ἀληθής,, or eliding the γὰρ,  ὁ  λέγων τὸν ἀληθῆ λόγον ἀληθῆ ἀληθής, (ho legon ton alethe logon alethe alethes) may be rendered as either: The statement which states that the true statement is true is true, or, more alla Grice, as He who says (or explicitly conveys, or indicates) that the true thesis is true says something true. It may be argued that it is quite baffling (and figurative or analogical or metaphoric) in this context, to take ἀληθής to be predicated  of the Griceian utterer, a person (true standing for truth teller, trustworthy), to take it to mean that he says something true, rather than his statement stating something true, or his statement being true. But cf. L and S: ἀληθής [α^], Dor. ἀλαθής, [α^], Dor. ἀλαθής, ές, f. λήθω, of persons, truthful, honest (not in Hom., v. infr.), ἀ. νόος Pi. O.2.92; κατήγορος A. Th. 439; κριτής Th. 3.56; οἶνος ἀ. `in vino veritas, Pl. Smp. 217e; ὁ μέσος ἀ. τις Arist. EN 1108a20. Admittedly, this or that non-Griceian passage in which it is λόγος, and not the utterer, which is the implied grammatical Subjects of ὁ λέγων can be found in Metaph. Γ7, 1012a24–25; Δ6, 1016a33; Int. 14, 23a28–29; De motu an. 10, 703a4; Eth. Nic. 2.6, 1107a6–7. 9. So the topic is controversial. Indeed such a non-Griceian exegesis of the passage is given by Alexander of Aphrodisias (in Metaph. 340. 26–29):9, when Alexander observes that the statement, i.e. not the utterer, that says that everything is false (ὁ δὲ πάντα ψευδῆ εἶναι λέγων λόγος) negates itself, not himself, because if everything is false, this very statement, which, rather than, by which the utterer, says that everything is false, would be false, and how can an utterer be FALSE? So that the statement which, rather than the utterer who, negates it, saying that not everything is false, would be true, and surely an utterer cannot be true. Does Alexander misrepresent Aristotles argument by omitting every Griceian reference to the asserter or utterer qua rational personal agent, of the thesis? If the answer is negative, even if the occurrence of ὁ λέγων at 1012b15 refers to the asserter, or utterer, qua rational personal agent, this is merely an accidental feature of Aristotles argument that cannot be regarded as an indication of its dialectical nature. None of this is to deny that some self-refutation argument may be of an intrinsically dialectical nature; it is only to deny that every one is This is in line with Burnyeats view that a dialectical self-refutation, even if qualified, as Aristotle does, as ancient, is a subspecies of self-refutation, but does not exhaust it. Granted, a dialectical approach may provide a useful interpretive framework for many an ancient self-refutation argument. A statement like If proof does not exist, proof exists ‒ that occurs in an anti-sceptical self-refutation argument reported by Sextus Empiricus  ‒ may receive an attractive dialectical re-interpretation. It may be argued that such a statement should not be understood at the level of what is explicated, but should be regarded as an elliptical reminder of a complex dialectical argument which can be described as follows. Cf. If thou claimest that proof doth not exist, thou must present a proof of what thou assertest, in order to be credible, but thus thou thyself admitest that proof existeth. A similar point can be made for Aristotles famous argument in the Protrepticus that one must philosophise. A number of sources state that this argument relies on the implicaturum, If one must not philosophize, one must philosophize. It may be argued that this implicaturum is an elliptical reminder of a dialectical argument such as the following. If thy position is that thou must not philosophise, thou must reflect on this choice and argue in its support, but by doing so thou art already choosing to do philosophy, thereby admitting that thou must philosophise. The claim that every instance of an ancient self-refutation arguments is of an intrinsically dialectical nature is thus questionable, to put it mildly. V also 340.19–26, and A.

One of Grice’s favorite paradoxes, that display the usefulness of the implicaturum are the so-called ‘paradoxes of implication.’ Johnson, alas, uses ‘paradox’ in the singular. So there must be earlier accounts of this in the history of philosophy. Notably in the ancient commentators to Philo! (Greek “ei” and Roman “si”). Misleading but true – could do.” Note that Grice has an essay on the ‘paradoxes of entailment’. As Strawson notes, this is misleading. For Strawson these are not paradoxes. The things are INCORRECT. For Grice, the Philonian paradoxes are indeed paradoxical because each is a truth. Now, Strawson and Wiggins challenge this. For Grice, to utter “if p, q” implicates that the utterer is not in a position to utter anything stronger. He implicates that he has NON-TRUTH-FUNCTIONAL REASON or grounds to utter “if p, q.” For Strawson, THAT is precisely what the ‘consequentialist’ is holding. For Strawson, the utterer CONVENTIONALLY IMPLIES that the consequent or apodosis follows, in some way, from the antecedent or protasis. Not for Grice. For Grice, what the utterer explicitly conveys is that the conditions that obtain are those of the Philonian conditional. He implicitly conveys that there is n inferrability, and this is cancellable. If Strawson holds that it is a matter of a conventional implicaturum, the issue of cancellation becomes crucial. For Grice, to add that “But I don’t want to covey that there is any inferrability between the protasis and the apodosis” is NOT a contradiction. The utterer or emissor is NOT self-contradicting. And he isn’t! The first to use the term ‘paracox’ here is a genius. Possibly Philo. It was W. E. Johnson who first used the expression 'paradox of implication', explaining that a paradox of this sort arises when a logician proceeds step by step, using accepted principles, until a formula is reached which conflicts with common sense [Johnson, 1921, 39].The paradox of implication assumes many forms,  some of which are not easily recognised as involving  mere varieties of the same fundamental principle. But     COMPOUND PROPOSITIONS 47   I believe that they can all be resolved by the consideration that we cannot ivithotd qjialification apply a com-  posite and (in particular) an implicative proposition to  the further process of inference. Such application is  possible only when the composite has been reached  irrespectively of any assertion of the truth or falsity of  its components. In other words, it is a necessary con-  dition for further inference that the components of a  composite should really have been entertained hypo-  thetically when asserting that composite.   § 9. The theory of compound propositions leads to  a special development when in the conjunctives the  components are taken — not, as hitherto, assertorically —  but hypothetically as in the composites. The conjunc-  tives will now be naturally expressed by such words as  possible or compatible, while the composite forms which  respectively contradict the conjunctives will be expressed  by such words as necessary or impossible. If we select  the negative form for these conjunctives, we should write  as contradictory pairs :   Conjunctives {possible) Composites {fiecessary)     a. p does not imply q   1, p is not implied by q   c. p is not co-disjunct to q   d. p is not co-alternate to q     a, p implies q   b, p is implied by q   c, p is co-disjunct to q   d, p is co-alternate to q     Or Otherwise, using the term 'possible' throughout,  the four conjunctives will assume the form that the several  conjunctions — pq^pq, pq ^-nd pq — are respectively /^i*-  sidle. Here the word possible is equivalent to being  merely hypothetically entertained, so that the several  conjunctives are now qualified in the same way as are  the simple components themselves. Similarly the four CHAPTER HI   corresponding composites may be expressed negatively  by using the term 'impossible,' and will assume the  form that the ^^;yunctions pq^ pq, pq and pq are re-  spectively impossible, or (which means the same) that  the ^zVjunctions/^, ^^, pq Rnd pq are necessary. Now  just as 'possible* here means merely 'hypothetically  entertained/ so 'impossible' and 'necessary' mean re-  spectively 'assertorically denied' and 'assertorically  affirmed/   The above scheme leads to the consideration of the  determinate relations that could subsist of p to q when  these eight propositions (conjunctives and composites)  are combined in everypossibleway without contradiction.  Prima facie there are i6 such combinations obtained by  selecting a or ay b or 3, c or c, d or J for one of the four  constituent terms. Out of these i6 combinations, how-  ever, some will involve a conjunction of supplementaries  (see tables on pp. 37, 38), which would entail the as-  sertorical affirmation or denial of one of the components  / or q, and consequently would not exhibit a relation of  p to q. The combinations that, on this ground, must be  disallowed are the following nine :   cihcd, abed, abed, abed] abed, bacd, cabd, dabc\ abed.   The combinations that remain to be admitted are  therefore the followino- seven :   abld, cdab\ abed, bald, cdab^ dcab\ abed.   In fact, under the imposed restriction, since a or b  cannot be conjoined with c or d, it follows that we must  always conjoin a with c and d\ b with e and d\ c with  a and b\ ^with a and b. This being understood, the     COMPOUND PROPOSITIONS 49   seven permissible combinations that remain are properly  to be expressed in the more simple forms:   ab, cd\ ab, ba, cd, dc\ and abed   These will be represented (but re-arranged for purposes  of symmetry) in the following table giving all the  possible relations of any proposition/ to any proposition  q.

This  latter terminology, however, is properly used to express  the formal relations of implication and opposition,  whereas the terminology which I have adopted will apply  indifferently both for formal and for material relations. One of Grice’s claims to fame is his paradox, under ‘Yog and Zog.’ Another paradox that Grice examines at length is paradox by Moore. For Grice, unlike Nowell-Smith, an utterer who, by uttering The cat is on the mat explicitly conveys that the cat is on the mat does not thereby implicitly convey that he believes that the cat is on the mat. He, more crucially expresses that he believes that the cat is on the mat ‒ and this is not cancellable. He occasionally refers to Moores paradox in the buletic mode, Close the door even if thats not my desire. An imperative still expresses someones desire. The sergeant who orders his soldiers to muster at dawn because he is following the lieutenants order. Grices first encounter with paradox remains his studying Malcolms misleading exegesis of Moore. Refs.: The main sources given under ‘heterologicality,’ above. ‘Paradox’ is a good keyword in The H. P. Grice Papers, since he used ‘paradox’ to describe his puzzle about ‘if,’ but also Malcolm on Moore on the philosopher’s paradox, and paradoxes of material implication and paradoxes of entailment. Grice’s point is that a paradox is not something false. For Strawson it is. “The so-called paradoxes of ‘entailment’ and ‘material implication’ are a misnomer. They statements are not paradoxical, they are false.” Not for Grice! Cf. aporia. The H. P. Grice Papers, BANC MSS 90/135c, The Bancroft Library, University of California, Berkeley.

Griceian paradigm, the-- paradigm: as used by physicist – Grice: “Kuhn ain’t a philosopher – his BA was in physics!” -- Kuhn in “The Structure of Scientific Revolutions,” 2, a set of scientific and metaphysical beliefs that make up a theoretical framework within which scientific theories can be tested, evaluated, and if necessary revised. Kuhn’s principal thesis, in which the notion of a paradigm plays a central role, is structured around an argument against the logical empiricist view of scientific theory change. Empiricists viewed theory change as an ongoing smooth and cumulative process in which empirical facts, discovered through observation or experimentation, forced revisions in our theories and thus added to our ever-increasing knowledge of the world. It was claimed that, combined with this process of revision, there existed a process of intertheoretic reduction that enabled us to understand the macro in terms of the micro, and that ultimately aimed at a unity of science. Kuhn maintains that this view is incompatible with what actually happens in case after case in the history of science. Scientific change occurs by “revolutions” in which an older paradigm is overthrown and is replaced by a framework incompatible or even incommensurate with it. Thus the alleged empirical “facts,” which were adduced to support the older theory, become irrelevant to the new; the questions asked and answered in the new framework cut across those of the old; indeed the vocabularies of the two frameworks make up different languages, not easily intertranslatable. These episodes of revolution are separated by long periods of “normal science,” during which the theories of a given paradigm are honed, refined, and elaborated. These periods are sometimes referred to as periods of “puzzle solving,” because the changes are to be understood more as fiddling with the details of the theories to “save the phenomena” than as steps taking us closer to the truth. A number of philosophers have complained that Kuhn’s conception of a paradigm is too imprecise to do the work he intended for it. In fact, Kuhn, fifteen years later, admitted that at least two distinct ideas were exploited by the term: i the “shared elements [that] account for the relatively unproblematic character of professional communication and for the relative unanimity of professional judgment,” and ii “concrete problem solutions, accepted by the group [of scientists] as, in a quite usual sense, paradigmatic” Kuhn, “Second Thoughts on Paradigms,” 7. Kuhn offers the terms ‘disciplinary matrix’ and ‘exemplar’, respectively, for these two ideas. Refs.: H. P. Grice, “Why Kuhn could never explain the ‘minor revolution’ in philosophy we had at Oxford!; H. P. Grice, “The Griceian paradigm – crisis – revolution – resolution: some implicatura from Kuhn (from Merton to St. John’s).”

paradigm-case argument: an argument designed by A. G. N. Flew, Grice’s first tutee at St. John’s – almost -- to yield an affirmative answer to the following general type of skeptically motivated question: Are A’s really B? E.g., Do material objects really exist? Are any of our actions really free? Does induction really provide reasonable grounds for one’s beliefs? The structure of the argument is simple: in situations that are “typical,” “exemplary,” or “paradigmatic,” standards for which are supplied by common sense, or ordinary language, part of what it is to be B essentially involves A. Hence it is absurd to doubt if A’s are ever B, or to doubt if in general A’s are B. More commonly, the argument is encountered in the linguistic mode: part of what it means for something to be B is that, in paradigm cases, it be an A. Hence the question whether A’s are ever B is meaningless. An example may be found in the application of the argument to the problem of induction. See Strawson, Introduction to Logical Theory, 2. When one believes a generalization of the form ‘All F’s are G’ on the basis of good inductive evidence, i.e., evidence constituted by innumerable and varied instances of F all of which are G, one would thereby have good reasons for holding this belief. The argument for this claim is based on the content of the concepts of reasonableness and of strength of evidence. Thus according to Strawson, the following two propositions are analytic: 1 It is reasonable to have a degree of belief in a proposition that is proportional to the strength of the evidence in its favor. 2 The evidence for a generalization is strong in proportion as the number of instances, and the variety of circumstances in which they have been found, is great. Hence, Strawson concludes, “to ask whether it is reasonable to place reliance on inductive procedures is like asking whether it is reasonable to proportion the degree of one’s convictions to the strength of the evidence. Doing this is what ‘being reasonable’ means in such a context” p. 257. In such arguments the role played by the appeal to paradigm cases is crucial. In Strawson’s version, paradigm cases are constituted by “innumerable and varied instances.” Without such an appeal the argument would fail completely, for it is clear that not all uses of induction are reasonable. Even when this appeal is made clear though, the argument remains questionable, for it fails to confront adequately the force of the word ‘really’ in the skeptical challenges. paradigm case argument paradigm case argument.

para-doxon: a seemingly sound piece of reasoning based on seemingly true assumptions that leads to a contradiction or other obviously false conclusion. A paradox reveals that either the principles of reasoning or the assumptions on which it is based are faulty. It is said to be solved when the mistaken principles or assumptions are clearly identified and rejected. The philosophical interest in paradoxes arises from the fact that they sometimes reveal fundamentally mistaken assumptions or erroneous reasoning techniques. Two groups of paradoxes have received a great deal of attention in modern philosophy. Known as the semantic paradoxes and the logical or settheoretic paradoxes, they reveal serious difficulties in our intuitive understanding of the basic notions of semantics and set theory. Other well-known paradoxes include the barber paradox and the prediction or hangman or unexpected examination paradox. The barber paradox is mainly useful as an example of a paradox that is easily resolved. Suppose we are told that there is an Oxford barber who shaves all and only the Oxford men who do not shave themselves. Using this description, we can apparently derive the contradiction that this barber both shaves and does not shave himself. If he does not shave himself, then according to the description he must be one of the people he shaves; if he does shave himself, then according to the description he is one of the people he does not shave. This paradox can be resolved in two ways. First, the original claim that such a barber exists can simply be rejected: perhaps no one satisfies the alleged description. Second, the described barber may exist, but not fall into the class of Oxford men: a woman barber, e.g., could shave all and only the Oxford men who do not shave themselves. The prediction paradox takes a variety of forms. Suppose a teacher tells her students on Friday that the following week she will give a single quiz. But it will be a surprise: the students will not know the evening before that the quiz will take place the following day. They reason that she cannot give such a quiz. After all, she cannot wait until Friday to give it, since then they would know Thursday evening. That leaves Monday through Thursday as the only possible days for it. But then Thursday can be ruled out for the same reason: they would know on Wednesday evening. Wednesday, Tuesday, and Monday can be ruled out by similar reasoning. Convinced by this seemingly correct reasoning, the students do not study for the quiz. On Wednesday morning, they are taken by surprise when the teacher distributes it. It has been pointed out that the students’ reasoning has this peculiar feature: in order to rule out any of the days, they must assume that the quiz will be given and that it will be a surprise. But their alleged conclusion is that it cannot be given or else will not be a surprise, undermining that very assumption. Kaplan and Montague have argued in “A Paradox Regained,” Notre Dame Journal of Formal Logic, 0 that at the core of this puzzle is what they call the knower paradox  a paradox that arises when intuitively plausible principles about knowledge and its relation to logical consequence are used in conjunction with knowledge claims whose content is, or entails, a denial of those very claims.  Paradoxa A philosophical treatise of Cicero setting forth six striking theorems of the Stoic system. It was composed in B.C. 46. Edited by Orelli (with the Tusculans) (Zürich, 1829); and by Möser (Göttingen, 1846).

The three modals: Grice: “We have, in all, then, three varieties of acceptability statement (each with alethic and practical sub-types), associated with the modals "It is fully acceptable that . . . " (non-defeasible), 'it is ceteris paribus acceptable that . . . ', and 'it is to such-and-such a degree acceptable that . . . ', both of the latter pair being subject to defeasibility. (I should re-emphasize that, on the practical side, I am so far concerned to represent only statements which are analogous with Kant's Technical Imperatives ('Rules of Skill').) I am now visited by a temptation, to which of course I shall yield, to link these varieties of acceptability statement with common modals; however, to preserve a façade of dignity I shall mark the modals I thus define with a star, to indicate that the modals so defined are only candidates for identification with the common modals spelled in the same way. I am tempted to introduce 'it must* be that' as a modal whose sense is that of 'It is fully acceptable that' and 'it ought* to be that' as a modal whose sense is that of 'It is ceteris paribus (other things being equal) acceptable that'; for degree-variant acceptability I can think of no appealing vernacular counterpart other than 'acceptable' itself. After such introduction, we could allow the starred modals to become idiomatically embedded in the sentences in which they occur; as in "A bishop must* get fed up with politicians", and in "To keep his job, a bishop ought* not to show his irritation with politicians". end p.78 But I now confess that I am tempted to plunge even further into conceptual debauchery than I have already; having just, at considerable pains, got what might turn out to be common modals into my structures, I am at once inclined to get them out again. For it seems to me that one might be able, without change of sense, to employ forms of sentence which eliminate reference to acceptability, and so do not need the starred modals. One might be able, to this end, to exploit "if-then" conditionals (NB 'if . . . then', not just 'if') together with suitable modifiers. One might, for example, be able to re-express "A bishop must* get fed up with politicians" as "If one is a bishop, then (unreservedly) one will get fed up with the politicians"; and "To keep his job, a bishop ought* not to show his irritation with politicians" as "If one is to keep one's job and if one is a bishop, then, other things being equal, one is not to show one's irritation with politicians". Of course, when it comes to applying detachment to corresponding singular conditionals, we may need to have some way of indicating the character of the generalization from which the detached singular non-conditional sentence has been derived; the devising of such indices should not be beyond the wit of man. So far as generalizations of these kinds are concerned, it seems to me that one needs to be able to mark five features: (1) conditionality; (2) generality; (3) type of generality (absolute, ceteris paribus, etc., thereby, ipso facto, discriminating with respect to defeasibility or indefeasibility); (4) mode; (5) (not so far mentioned) whether or not the generalization in question has or has not been derived from a simple enumeration of instances; because of their differences with respect to direction of fit, any such index will do real work in the case of alethic generalities, not in the case of practical generalities. So long as these features are marked, we have all we need for our purposes. Furthermore, they are all (in some legitimate and intelligible sense) formal features, and indeed features which might be regarded as, in some sense, 'contained in' or 'required by' the end p.79 concept of a rational being, since it would hardly be possible to engage in any kind of reasoning without being familiar with them. So, on the assumption that the starred modals are identifiable with their unstarred counterparts, we would seem to have reached the following positions. (1) We have represented practical and alethic generalizations, and their associated conditionals, and with them certain common modals such as 'must' and 'ought', under a single notion of acceptability (with specific variants). (2) We have decomposed acceptability itself into formal features. (3) We have removed mystery from the alleged logical fact that acceptable practical 'ought' statements have to be derivable from an underlying generalization. (4) Though these achievements (if such they be) might indeed not settle the 'univocality' questions, they can hardly be irrelevant to them. I suspect that, if we were to telephone the illustrious Kant at his Elysian country club in order to impart to him this latest titbit of philosophical gossip, we might get the reply, "Big deal! Isn't that what I've been telling you all along?"

paradoxes of omnipotence – Grice: “a favourite with the second Wilde.” – Grice means first Wilde, reader in philosophical psychology, second Wilde, reader in natural religion -- a series of paradoxes in philosophical theology that maintain that God could not be omnipotent because the concept is inconsistent, alleged to result from the intuitive idea that if God is omnipotent, then God must be able to do anything. 1 Can God perform logically contradictory tasks? If God can, then God should be able to make himself simultaneously omnipotent and not omnipotent, which is absurd. If God cannot, then it appears that there is something God cannot do. Many philosophers have sought to avoid this consequence by claiming that the notion of performing a logically contradictory task is empty, and that question 1 specifies no task that God can perform or fail to perform. 2 Can God cease to be omnipotent? If God can and were to do so, then at any time thereafter, God would no longer be completely sovereign over all things. If God cannot, then God cannot do something that others can do, namely, impose limitations on one’s own powers. A popular response to question 2 is to say that omnipotence is an essential attribute of a necessarily existing being. According to this response, although God cannot cease to be omnipotent any more than God can cease to exist, these features are not liabilities but rather the lack of liabilities in God. 3 Can God create another being who is omnipotent? Is it logically possible for two beings to be omnipotent? It might seem that there could be, if they never disagreed in fact with each other. If, however, omnipotence requires control over all possible but counterfactual situations, there could be two omnipotent beings only if it were impossible for them to disagree. 4 Can God create a stone too heavy for God to move? If God can, then there is something that God cannot do  move such a stone  and if God cannot, then there is something God cannot do  create such a stone. One reply is to maintain that ‘God cannot create a stone too heavy for God to move’ is a harmless consequence of ‘God can create stones of any weight and God can move stones of any weight.’   paradox of analysis: Grice: “One (not I, mind – I don’t take anything seriously) must take the paradox of analysis very seriously.” an argument that it is impossible for an analysis of a meaning to be informative for one who already understands the meaning. Consider: ‘An F is a G’ e.g., ‘A circle is a line all points on which are equidistant from some one point’ gives a correct analysis of the meaning of ‘F’ only if ‘G’ means the same as ‘F’; but then anyone who already understands both meanings must already know what the sentence says. Indeed, that will be the same as what the trivial ‘An F is an F’ says, since replacing one expression by another with the same meaning should preserve what the sentence says. The conclusion that ‘An F is a G’ cannot be informative for one who already understands all its terms is paradoxical only for cases where ‘G’ is not only synonymous with but more complex than ‘F’, in such a way as to give an analysis of ‘F’. ‘A first cousin is an offspring of a parent’s sibling’ gives an analysis, but ‘A dad is a father’ does not and in fact could not be informative for one who already knows the meaning of all its words. The paradox appears to fail to distinguish between different sorts of knowledge. Encountering for the first time and understanding a correct analysis of a meaning one already grasps brings one from merely tacit to explicit knowledge of its truth. One sees that it does capture the meaning and thereby sees a way of articulating the meaning one had not thought of before. Refs.: H. P. Grice: “Dissolving the paradox of analysis via the principle of conversational helpfulness – How helpful is ‘unmarried male’ as an analysis of ‘bachelor’?” paradox of omniscience: Grice: “A favourite with the second Wilde,” i. e. the Wilde reader in natural religion, as opposed to the Wilde reader in philosophical psychology -- an objection to the possibility of omniscience, developed by Patrick Grim, that appeals to an application of Cantor’s power set theorem. Omniscience requires knowing all truths; according to Grim, that means knowing every truth in the set of all truths. But there is no set of all truths. Suppose that there were a set T of all truths. Consider all the subsets of T, that is, all members of the power set 3T. Take some truth T1. For each member of 3T either T1 is a member of that set or T1 is not a member of that set. There will thus correspond to each member of 3T a further truth specifying whether T1 is or is not a member of that set. Therefore there are at least as many truths as there are members of 3T. By the power set theorem, there are more members of 3T than there are of T. So T is not the set of all truths. By a parallel argument, no other set is, either. So there is no set of all truths, after all, and therefore no one who knows every member of that set. The objection may be countered by denying that the claim ‘for every proposition p, if p is true God knows that p’ requires that there be a set of all true propositions. 
paraphilosophy: “I phoned Gellner: you chould entitle your essay, an attack on ordinary language PARA-philosophy, since that is what Austin asks us to do.”

Paraphilosophy: “Something Austin loved, and I not so much.” – Grice.

para-psychology, the study of certain anomalous phenomena and ostensible causal connections neither recognized nor clearly rejected by traditional science. Parapsychology’s principal areas of investigation are extrasensory perception ESP, psychokinesis PK, and cases suggesting the survival of mental functioning following bodily death. The study of ESP has traditionally focused on two sorts of ostensible phenomena, telepathy the apparent anomalous influence of one person’s mental states on those of another, commonly identified with apparent communication between two minds by extrasensory means and clairvoyance the apparent anomalous influence of a physical state of affairs on a person’s mental states, commonly identified with the supposed ability to perceive or know of objects or events not present to the senses. The forms of ESP may be viewed either as types of cognition e.g., the anomalous knowledge of another person’s mental states or as merely a form of anomalous causal influence e.g., a distant burning house causing one to have  possibly incongruous  thoughts about fire. The study of PK covers the apparent ability to produce various physical effects independently of familiar or recognized intermediate sorts of causal links. These effects include the ostensible movement of remote objects, materializations the apparently instantaneous production of matter, apports the apparently instantaneous relocation of an object, and in laboratory experiments statistically significant non-random behavior of normally random microscopic processes such as radioactive decay. Survival research focuses on cases of ostensible reincarnation and mental mediumship i.e., “channeling” of information from an apparently deceased communicator. Cases of ostensible precognition may be viewed as types of telepathy and clairvoyance, and suggest the causal influence of some state of affairs on an earlier event an agent’s ostensible precognitive experience. However, those opposed to backward causation may interpret ostensible precognition either as a form of unconscious inference based on contemporaneous information acquired by ESP, or else as a form of PK possibly in conjunction with telepathic influence by which the precognizer brings about the events apparently precognized. The data of parapsychology raise two particularly deep issues. The evidence suggesting survival poses a direct challenge to materialist theories of the mental. And the evidence for ESP and PK suggests the viability of a “magical” worldview associated usually with so-called primitive societies, according to which we have direct and intimate access to and influence on the thoughts and bodily states of others. H. P. Grice: "When, in the late 1940s, J. L. Austin instituted his *second* playgroup, for full-time philosophy dons -- my *first*, in a way --, its official rationale, given by its founder, was that all its members were hacks, spending our weekdays wrestling with the dissolution of this or that philosophical pseudo-problem, and that we deserved to be spending our Saturday mornings -- my Saturday afternoons were consacrated to the Demi-Johns -- in restorative para-philosophy. And so we started on such  topics as maps and diagrams and (in another term) rules of games." Refs.: H. P. Grice, “What J. L Austin meant by ‘paraphilosophy’!,” H. P. Grice, “Philosophy and para-philosophy.”

Pareto: one of the most important Italian philosophers, born in Paris (“His mother was a French woman.” – Grice.).  Pareto’s efficiency, also called Pareto optimality, a state of affairs in which no one can be made better off without making someone worse off. “If you are provided information, the one who gives you information loses.” “If you give information, you lose.” “If you influence, you win.” “If you get influenced,” you lose.” The  economist Vilfredo Pareto referred to ‘optimality,’ as used by Grice, rather than efficiency, but usage has drifted toward the less normative term, ‘efficiency.’ Pareto supposes that the utilitarian addition of welfare across conversationalist A and conversationalist B is meaningless. Pareto concludes that the only useful aggregate measures of welfare must be ordinal. One state of affairs is what Pareto calls “Pareto-superior” to another if conversationalist A cannot move to the second state without making his co-conversationalist B worse off. Although Pareto’s criterion is generally thought to be positive or descriptive (‘empiricist’) rather than normative (‘quasi-contractual, or rational’), it is often used as a normative principles for justifying particular changes or refusals to make changes. Some philosophers, such as Grice’s tutee Nozick, for example, take the Pareto criterion as a moral constraint and therefore oppose certain government policies. In the context of a voluntary exchange, it makes sense to suppose that every exchange is “Pareto-improving,” at least for the direct parties to the exchange, conversationalists A and B. If, however, we fail to account for any external effect of A’s and B’s conversational exchange on a third party, the conversational exchange may *not* be Pareto-improving (Grice’s example, “Mrs. Smith is a bag.”. Moreover, we may fail to provide collective, or intersubjective benefits that require the co-operation or co-ordination of A’s and B’s individual efforts (A may be more ready to volunteer than B, say). Hence, even in a conversational exchange, we cannot expect to achieve “Pareto efficiency,” but what Grice calls “Grice efficiency.” We might therefore suppose we should invite thet intervention of the voice of reason to help us helping each other. But in a typical conversational context, it is often hard to believe that a significant policy change can be Pareto-improving: there are sure to be losers from any change – “but the it’s gentlemanly to accept a loss.” – H. P. Grice.  Vilfredo Federico Damaso Pareto (n. Parigi, 15 luglio 1848 – Céligny, 19 agosto 1923) è stato un ingegnere, economista e sociologo italiano.  Con Gaetano Mosca fu tra i teorici della corrente politica dell'elitismo. Di grande versatilità mentale, Pareto è stato tra le menti più eclettiche vissute nella seconda metà dell'Ottocento e all'inizio Novecento. Le sue capacità spaziavano dall'economia politica, alla teoria dei giochi, all'ingegneria, alla matematica, alla statistica e alla filosofia.  Pareto ha assunto un ruolo determinante nel rafforzare con rigore scientifico e analitico i concetti cardine della teoria neoclassica elaborata da Léon Walras, Carl Menger e William Stanley Jevons nell'ambito delle scienze economiche, facendo sì che si affermasse rispetto alle altre in sviluppo o precedenti, e che dominasse come scuola incontrastata fino alla metà del '900. Ancora oggi, i contributi di Pareto sono centrali e largamente discussi a livello internazionale in economia e in quasi tutti i campi applicativi di essa, come la matematica, la statistica e la teoria dei giochi. Fu lui il primo a utilizzare il termine élite in campo sociologico.[senza fonte Nacque a Parigi da padre italiano, Raffaele Pareto (1812-1882), un ingegnere in esilio volontario per motivi politici appartenente a un'antica famiglia nobile genovese, e da madre francese, Marie Métenier (1813-1889). Suo zio paterno era il celebre geologo Lorenzo Pareto (1800-1865). Rientrò in Italia con la famiglia e si stabilì a Genova, nei primi anni cinquanta dell'Ottocento. Pareto frequentò il Regio Istituto Tecnico e l'Università a Torino, conseguendo il diploma di Scienze Matematiche presso l'Università e laureandosi infine presso la Scuola di Applicazione per Ingegneri nel 1870, con una tesi sui "Principi fondamentali della teoria della elasticità dei corpi solidi e ricerche sulla integrazione delle equazioni differenziali che ne definiscono l'equilibrio".[1] Dopo un periodo trascorso come ingegnere straordinario, a Firenze, presso la Società anonima delle strade ferrate, nel 1880 divenne direttore generale della Società delle ferriere italiane, a San Giovanni Valdarno.  In questo stesso periodo frequentò i circoli culturali fiorentini e, con articoli su riviste italiane ed europee, partecipò intensamente al dibattito politico su posizioni liberiste e anti-protezionistiche. Nel 1880 e nel 1882 presentò la propria candidatura come deputato, prima nel collegio di Montevarchi, poi nel collegio Pistoia-Prato-San Marcello, ma non fu eletto. Intanto, coltivò i suoi interessi culturali, approfondendo l'economia, la sociologia, gli studi letterari classici. Nel 1889 sposò la russa Alexandra Bakunin (non imparentata con l'anarchico rivoluzionario Michail Bakunin).[2] Nel 1890 conobbe il già insigne economista Maffeo Pantaleoni, cui restò legato da sincera amicizia per il resto della sua vita. Anche grazie a Pantaleoni, nel 1894 fu nominato professore ordinario di economia politica all'Università di Losanna, dove prima di lui aveva insegnato Léon Walras.  Lavorò allo sviluppo e alla sistemazione della teoria dell'equilibrio economico tenendo, nel 1901, alcune conferenze a Parigi, invitato da Georges Sorel, con il quale fu in ottimi rapporti. In questo periodo fu abbandonato dalla moglie ed ereditò una grossa fortuna da uno zio. Si legò more uxorio con Jeanne Régis, una giovane parigina conosciuta tramite un'inserzione su un giornale. Intanto, diventava sempre più vivo l'interesse per la teoria sociologica. Abbandonò progressivamente l'insegnamento, anche per ragioni di salute, e si dedicò alla redazione del Trattato di sociologia generale. Nel 1910 Pareto pubblicò Il mito virtuista e la letteratura immorale, uno scritto mordace e satirico sul fenomeno Virtuista, nel quale l'autore demitizza in maniera irriverente tutte le razionalizzazioni degli uomini bigotti e ipocriti del suo tempo. Frattanto proseguì l'attività pubblicistica, che s'intensificò dopo la pubblicazione del Trattato, avvenuta nel 1916.  Fu in rapporti di amicizia con Benito Mussolini, che conobbe tra il 1902 e il 1904 quando l'ancora agitatore socialista era rifugiato in Svizzera e frequentava le lezioni dell'economista. Mussolini fece suoi i principi della "filosofia della vita" di Pareto, che considererà Mussolini "un grande statista". Nell'ottobre 1922 Pareto dalla Svizzera, con un acceso telegramma in cui diceva "ora o mai più", inviò il proprio incoraggiamento a Benito Mussolini a dare il via alla Marcia su Roma e prendere il potere[3]. Alla fine del 1922 accettò l'invito fattogli da Benito Mussolini, diventato capo del governo, a rappresentare l'Italia nella commissione per la riduzione degli armamenti presso la Società delle Nazioni. Il 1º marzo del 1923, su proposta del governo fascista, fu nominato Senatore del Regno. La nomina non poté essere portata a termine perché Pareto non consegnò alla presidenza del Senato i documenti richiestigli. Il 19 giugno dello stesso anno, ottenuto il divorzio da Alexandra Bakunin, sposò Jeanne Régis dopo una convivenza ventennale.[2]  Morì il 19 agosto successivo e fu sepolto nel cimitero di Céligny.  Nel corso della sua vita, oltre alle personalità già menzionate, intrattenne rapporti d'amicizia e di scambi culturali, spesso polemici, con Galileo Ferraris, Ubaldino ed Emilia Peruzzi, Ernest Naville, Yves Guyot, Gustave de Molinari, Antonio De Viti De Marco, Domenico Comparetti, Augusto Franchetti, Arturo Linaker, Ernesto Teodoro Moneta, William Ewart Gladstone, Filippo Turati, James Bryce, Alfred de Foville, Francis Ysidro Edgeworth, Adrien Naville, Ettore Ciccotti, Arturo Labriola, Benedetto Croce, Luigi Einaudi, Giovanni Papini, Giovanni Vailati, Tullio Martello, Luigi Amoroso, Joseph Schumpeter, L. V. Furlan, Napoleone Colajanni, Gaetano Salvemini, Vittore Pansini, Olinto Barsanti, Robert Michels, Corrado Gini, Dino Grandi e Carlo Placci.  Il resoconto giornalistico di una sua conferenza, tenuta nel giugno del 1891, sciolta d'autorità per l'intervento della polizia, dice: «La scienza economica non considera la proprietà come un dogma, non ne nega i difetti, la riconosce variabile nel tempo e nello spazio; ma seguendo il metodo sperimentale crede che la sua disparizione farebbe oggi più danni che vantaggi» Riguardo al suo contributo alla teoria economica, egli, assieme a Johann Heinrich von Thünen, Hermann Heinrich Gossen, Carl Menger, William Jevons e il già nominato Léon Walras, è stato tra i maggiori rappresentanti dell'indirizzo marginalistico o neo-classico, in contrapposizione alla scuola classica dei primi economisti che ha in Adam Smith e in David Ricardo i suoi capostipiti. A questa impostazione, fondata sul tentativo di trasferire nella scienza economica il metodo sperimentale delle scienze fisiche, con il conseguente uso delle matematiche, e che poi ha dominato lungo tutto il Novecento, si possono ricondurre concetti tipicamente paretiani come la curva della distribuzione dei redditi, il concetto detto poi di ottimo paretiano, le curve di indifferenza, il concetto di distribuzione paretiana.  Restando al concetto della curva della distribuzione dei redditi, o legge di Pareto, essa è l'estrapolazione statistica operata da Pareto del fatto che, non solo il numero di percettori di reddito medio è più elevato del numero di coloro che percepiscono redditi molto sopra e molto sotto la media, ma anche del fatto che, man mano che si considerano livelli di reddito sempre più alti, il numero dei percettori diminuisce in un modo che è all'incirca uguale in tutti i paesi e in tutte le epoche. Tale legge è stata poi variamente affinata e modificata sia nella sua base empirica che nella formalizzazione matematica, ma è rimasto il problema di sapere se la distribuzione dei redditi è probabilistica, e dunque risultante dalle abilità naturali umane distribuite casualmente in una popolazione, oppure influenzata da fattori ambientali che quindi generano ingiustizie.  In definitiva, come si vede, dal marginalismo, e in particolare dagli sviluppi apportati da Pareto, viene fuori una metodologia utile, al di là dei regimi economici preferiti, ad affrontare problemi di remunerazione e di allocazione delle risorse. L'indice di Pareto è tuttora una misura delle ineguaglianze della distribuzione dei redditi. Tuttavia, negli ultimi decenni del XX secolo, l'impostazione marginalistica, e quindi anche quella di Pareto, è stata soggetta a critiche stringenti. Si è infatti obiettato che non sempre ciò che l'agente sceglie è ciò che egli preferisce, nel senso che l'agente economico non è quell'attore perfettamente razionale che l'approccio marginalista presuppone. I neoclassici rispondono che il loro modello non si applica ad ogni individuo ma solo al consumatore rappresentativo o medio. Per quanto concerne l'ottimo paretiano, una critica particolarmente incisiva è stata quella di Amartya Sen che, tra l'altro in un suo lavoro del 1970, argomenta, sulla scorta del Teorema di Arrow, l'impossibilità matematica del liberismo paretiano. Proprio sul terreno delle costanti della natura umana e della razionalità dell'agente avviene il passaggio di Pareto dall'economia alla sociologia. Lo studio statistico della distribuzione dei redditi gli aveva fornito una prima evidenza della stabilità della natura umana pur nel variare delle situazioni storico-geografiche. D'altra parte, l'osservazione del comportamento non solo economico, ma più generalmente sociale, lo portava a constatare come l'individuo sociale agisca solo raramente secondo una razionalità strumentale di mezzi adeguati al fine. A suo modo, egli anticipa la critica antimarginalista ma, invece di rispondervi restando nel recinto dell'analisi economica, passa a fondare quella che egli chiamava la «sociologia scientifica». Il punto di partenza di questa nuova sociologia che, a suo dire, né Comte né Spencer erano stati in grado di concepire, è che nella maggior parte dei casi, l'individuo sociale si comporta in maniera non logica, ovvero senza uno scopo apparente e, comunque, senza una chiara coscienza dello scopo perseguito.  Un marinaio dell'antica Grecia che, apprestandosi a navigare, compie un sacrificio agli dei, realizza un'azione in nulla adeguata o utile al suo scopo di navigare. E quando parliamo, non abbiamo nessuna coscienza esplicita delle competenze grammaticali che utilizziamo per raggiungere lo scopo di enunciare frasi ben formate. Il problema è però che l'individuo sociale, pur agendo in modo non logico, cosa che lo accomuna alle specie animali, rispetto a queste ultime presenta la caratteristica di accompagnare i propri comportamenti con delle formulazioni verbali, la cui funzione è quella di fornire un motivo del comportamento stesso. Si muore in combattimento per qualcosa che chiamiamo patria, e allo stesso tempo si sottoscrive al motto che vuole che sia dolce e meritevole di lode il morire per la patria. La sociologia scientifica dovrà allora spiegare quali sono le costanti del comportamento sociale non logico, e quali sono le caratteristiche e la funzione del discorso sociale.  Da questo nucleo di problemi nasce la sociologia di Pareto, costituita da quattro grandi contrafforti: la teoria dell'azione non logica, la teoria dei residui e delle derivazioni, la teoria delle élite, la teoria dell'equilibrio sociale. Quanto alla teoria dell'azione non logica, oltre a ciò che si è già anticipato, si può aggiungere che essa costituisce una classificazione dei comportamenti sociali nei suoi aspetti percettivo-motori e linguistico-cognitivi. Un particolare interesse è rivolto verso i comportamenti linguistici. Per Pareto, il linguaggio in quanto competenza grammaticale è il tipo puro di azione non logica.  La teoria dei residui e delle derivazioni intende spiegare natura e funzionamento delle manifestazioni simboliche, o derivate, che accompagnano il comportamento sociale, e in particolare natura e funzionamento del discorso sociale. I motivi che l'individuo sociale adduce a giustificazione dei suoi comportamenti, sono, secondo Pareto, arbitrari rispetto alle effettive motivazioni dell'agire. Nonostante ciò, dalla grande varietà di essi, è possibile risalire alle costanti della natura umana - in termini più attuali, della mente sociale. Dai discorsi è possibile, dunque, risalire ai residui, o motivazioni costanti dell'agire, e alle tecniche verbali, o derivazioni, tramite le quali vengono prodotti i discorsi. In questo senso, la teoria dei residui e delle derivazioni è, al tempo stesso, una teoria della cognizione sociale e una teoria delle tecniche argomentative che l'individuo sociale adopera nella costruzione dei suoi discorsi.  Questo schema analitico non sempre è perseguito in maniera limpida, soprattutto per i residui. Tuttavia, ciò che emerge abbastanza chiaramente è che la cognizione sociale, nei suoi scambi con l'ambiente, incorpora una tendenza alle combinazioni e una tendenza agli aggregati. La prima genera le novità. La seconda assicura la stabilità. Questo livello psicologico è duplicato da un livello normativo che, a sua volta, presenta due tendenze, il mantenimento dell'ordine e la sua trasformazione sulla base di istanze di giustizia. In questo modo, il comportamento dell'individuo sociale, anche nei suoi aspetti più minuti e ripetitivi, appare sempre cognitivamente marcato e normativamente orientato. Uno dei difetti di questo sofisticato modello della cognizione sociale è, tuttavia, quello di operare con un concetto di norma assai ristretto, che nega l'incidenza pratica di ciò che Pareto chiama gli «equilibri ideali», ovvero ciò che un filosofo come Kant chiamerebbe gli ideali della ragione universale. L'agire dell'individuo sociale appare così rinchiuso entro un rapporto costrittivo di conformismo e di eterodirezione.   Gaetano Mosca: politologo italiano Venendo alla teoria delle élite, essa è un'ulteriore conseguenza dell'ipotesi di Pareto circa, non solo la costanza della natura umana, ma anche di una sua preminenza sui fattori ambientali. In ogni ramo dell'attività sociale, sostiene Pareto, vi sono individui che, sulla base di determinate abilità, eccellono. Pertanto, in forza di questo fatto, costoro entrano a far parte dell'élite corrispondente, pur in presenza di fattori distorsivi. L'attenzione di Pareto si appunta sull'élite politica, ma la sua teoria delle élite non è solo una teoria del rapporto tra governanti e governati, ma più generalmente una teoria della stratificazione sociale su base naturale. Questo è sicuramente ciò che la differenzia dalla coeva teoria della classe governante di Gaetano Mosca, fra i fondatori della moderna scienza politica, cui lo si associa ormai acriticamente, benché Pareto, a ragione, abbia sempre rivendicato l'autonomia della sua teorizzazione.  Tuttavia, come affermato, vi è in Pareto una particolare attenzione per il rapporto tra l'élite di governo, cioè coloro che eccellono nell'arte del comando politico, e i governati. La storia, egli afferma, è un cimitero di élite, ovvero un susseguirsi di sempre nuovi ma, nella loro struttura, sempre immodificabili rapporti unilaterali di rispetto tra governanti e governati. Infine, a coronamento di questo grandioso edificio, sta la teoria dell'equilibrio sociale. La quale, tuttavia, è la parte più debole di tutta la sua costruzione. Pareto è conscio dell'impossibilità di una formalizzazione matematica. Inoltre, la scelta di un concetto di equilibrio come equilibrio meccanico, rende questa parte della sua sociologia una faticosa argomentazione intorno ai vincoli sistemici dell'agire degli individui sociali. Di notevole vi è sicuramente il tentativo di Pareto di spiegare il divenire sociale senza rinunciare al presupposto della costanza della natura umana.  Ne deriva un pessimismo "ondulatorio" che non riesce però a conciliare il susseguirsi dei cicli sociali con il fatto, pur riconosciuto, del progressivo stabilirsi della «ragione» nelle attività umane. Pur con questo e altri limiti, che si sono venuti man mano segnalando, Pareto, nel suo tentativo di una «sociologia scientifica», desta ammirazione anzitutto per la creatività e la grandezza di vedute con cui ha saputo districarsi dalle difficoltà del paradigma economico marginalistico, alla cui piena ma problematica maturità aveva contribuito egli stesso; in secondo luogo, per averci assicurato una fra le più originali indagini intorno alla mente dell'individuo sociale, la cui portata è ancora in larga parte da valutare e sfruttare.  Il rapporto di Pareto con la sociologia scientifica nell'età della fondazione si innesta in modo paradigmatico nel momento in cui egli, partendo proprio dall'economia politica, critica il positivismo come sistema totalizzante e metafisico privo di un rigoroso metodo logico-sperimentale. In questo senso si può leggere il destino della produzione paretiana all'interno di una storia delle scienze sociali che continua a mostrare nel XXI secolo la sua peculiarità e tutto l'interesse per i suoi contributi (Giovanni Busino, Sugli studi paretiani all'alba del XXI secolo in Omaggio a Vilfredo Pareto Numero monografico in memoria di Giorgio Sola a cura di Stefano Monti Bragadin, "Storia Politica Società", Quaderni di Scienze Umane, anno IX, n. 15, giugno-dicembre 2009, p. 1 e sg.). La vicenda di Pareto si colloca anche nell'alveo della ricerca multidisciplinare di un modello scientifico che privilegia la sociologia come critica dei modelli cumulativi di sapere nonché come disciplina tendente all'affermazione di modelli relazionali della/nella scienza (Guglielmo Rinzivillo, Vilfredo Pareto e i modelli interdisciplinari nella scienza, "Sociologia", A. XXIX, n.1, Nuova Serie, 1995, pp. 207–222; si v. anche in Una epistemologia senza storia, Roma, Nuova Cultura, 2013, pp. 13–29, ISBN 978-88-6812-222-5). Niccolò Machiavelli Riguardo al suo pensiero politico, Pareto fu il primo a introdurre il concetto di élite, che trascende quello di classe politica e comprende l'analisi dei vari tipi di élite. È un liberista, insegna per un certo periodo economia politica all'università di Losanna. La sua teoria delle élite trae origine da un'analisi dell'eterogeneità sociale e dalla constatazione delle disuguaglianze, in termini di ricchezza e di potere, presenti nella società. Pareto intende studiare scientificamente queste disuguaglianze, percepite da lui come naturali. Nel corso del suo sviluppo, ogni società ha dovuto di volta in volta misurarsi con il problema dello sfruttamento e delle distribuzione di risorse scarse. L'ottimizzazione di queste risorse è quella che viene assicurata, in ogni ramo di attività, dagli individui dotati di capacità superiori: l'élite.  È interessato in particolar modo alla circolazione delle élite: "la storia è un cimitero di élite". A un certo punto l'élite non è più in grado di produrre elementi validi per la società e decade; nelle élite si verificano due tipi di movimenti: uno orizzontale (movimenti all'interno della stessa élite) e uno verticale (ascesa dal basso o declassamento dall'élite). Altro punto cardine della teoria paretiana è che l'umanità agisce principalmente secondo azioni non logiche. Tali azioni non logiche (si badi, è una cosa diversa da illogiche) prendono il nome di residui: manifestazione di qualcosa di non razionale che condiziona la nostra vita. Fra le sei classi di residui individuate da Pareto due sono fondamentali: l'istinto delle combinazioni (propensione al cambiamento) e la persistenza degli aggregati (tendenza alla conservazione delle tradizioni).  Se in un'élite prevale l'istinto delle combinazioni essa sarà aperta, propensa all'avvento di nuovi ingressi; se, viceversa, prevale la persistenza degli aggregati sarà chiusa, propensa a scarsa circolazione, ecc. Per giustificare a posteriori le proprie azioni e difendere i propri interessi si fa ricorso alle derivazioni: attribuiscono all'agire politico la connotazione di oggettiva necessità sociale (sono perciò, per sommi capi, assimilabili alla nozione di formula politica di Gaetano Mosca). Pareto si dichiara realista e seguace di Machiavelli, la sua è una descrizione della realtà con sfondi piuttosto pessimistici. È conservatore, teme il suffragio universale, in economia ha fiducia nel liberismo e nel libero mercato; è antisocialista, anche alla luce di quanto accade nella Russia della rivoluzione d'ottobre. Analizzando alcuni brani tratti da I sistemi socialisti si possono trarre alcune considerazioni sull'impianto teorico di Pareto:  Chi è al potere è anche, necessariamente, il più ricco: chi sta in alto non gode solo di potere politico, ma di tutta una serie di privilegi, L'élite svetta per le sue qualità, che possono essere sia buone che cattive, Le élite sono tutte colpite da una decadenza piuttosto rapida, Una élite che non si rigenera è destinata a perire brevemente (traspaiono, qui, retaggi tipici del darwinismo sociale [citazione?]), Elementi di ricambio per le élite possono provenire dalle classi rurali, le quali subiscono una selezione più forte rispetto alle classi agiate; le classi agiate tendono a salvare tutti i loro figli, facendo sì che rimangano in vita anche elementi deboli e non adatti. Questo significa che l'élite al potere avrà in sé anche gli elementi peggiori e ciò la destina a peggiorare, Ricorso alla metafora del fiore: l'élite è come un fiore, appassisce, ma se la pianta, cioè la società, è sana, essa farà subito nascere un altro fiore. La filosofia della storia di Pareto si fonda sulla circolazione continua delle élite. Non esiste per Pareto un'idea trionfante in politica, vede la storia come un moto ondoso: l'idea che trionfa oggi domani decade, ma dopodomani potrà tornare in auge. Analizzando alcuni brani tratti dal Trattato di sociologia generale si possono trarre alcune considerazioni sul pensiero di Pareto:  Non c'è netta separazione tra azione logica e azione non logica: un'azione concreta presenta in misura differente tratti di entrambe le categorie, I residui fanno sì che i comportamenti umani si differenzino e non vi siano piattezza e omologazione: permettono, quindi, la circolazione, Chi studia l'eticità e la morale di un popolo lo fa sempre con interesse: egli dà una qualifica alla morale perché la vuole imporre. In realtà la morale è qualcosa di molto difficile da qualificare e da imporre: la morale non è logica ma residuale (questo è certamente un discorso libertario). Chi governa non lo fa per il bene della collettività ma esclusivamente per il proprio interesse: la necessità di giustificarsi agli occhi dei governati lo fa ricorrere alle derivazioni. Le clientele in democrazia hanno un ruolo simile a quello dei vassalli nel feudalesimo. La democrazia così come la intendono i teorici (cioè come governo popolare) non è altro che un "pio desiderio". Clientelismo e consorterie non sono una degenerazione della democrazia: sono invece la realtà della democrazia: non è mai esistita una democrazia non interessata da questi fenomeni e la storia lo dimostra. Ci sarà sempre chi, stringendo un patto con le élite al potere, ne trae personale beneficio a scapito degli altri. "Il governare è l'arte di adoperare i sentimenti esistenti", questa frase dimostra il pragmatismo di Pareto.  Opere  Compendio di sociologia generale, 1920 (FR) Cours d'Économie politique professé a l'Université de Lausanne, vol.

Griceian-cum-Parfitian identity: “Parfait identity” – Grice: “Oddly, the Strawsons enjoy to involve themselves with issues of identity.” Parfit cites H. P. Grice on “Personal identity,” philosopher internationally known for his major contributions to the metaphysics of persons, moral theory, and practical reasoning. Parfit first rose to prominence by challenging the prevalent view that personal identity is a “deep fact” that must be all or nothing and that matters greatly in rational and moral deliberations. Exploring puzzle cases involving fission and fusion, Parfit propounded a reductionist account of personal identity, arguing that what matters in survival are physical and psychological continuities. These are a matter of degree, and sometimes there may be no answer as to whether some future person would be me. Parfit’s magnum opus, Reasons and Persons 4, is a strikingly original book brimming with startling conclusions that have significantly reshaped the philosophical agenda. Part One treats different theories of morality, rationality, and the good; blameless wrongdoing; moral immorality; rational irrationality; imperceptible harms and benefits; harmless torturers; and the self-defeatingness of certain theories. Part Two introduces a critical present-aim theory of individual rationality, and attacks the standard selfinterest theory. It also discusses the rationality of different attitudes to time, such as caring more about the future than the past, and more about the near than the remote. Addressing the age-old conflict between self-interest and morality, Parfit illustrates that contrary to what the self-interest theory demands, it can be rational to care about certain other aims as much as, or more than, about our own future well-being. In addition, Parfit notes that the self-interest theory is a hybrid position, neutral with respect to time but partial with respect to persons. Thus, it can be challenged from one direction by morality, which is neutral with respect to both persons and time, and from the other by a present-aim theory, which is partial with respect to both persons and time. Part Three refines Parfit’s views regarding personal identity and further criticizes the self-interest theory: personal identity is not what matters, hence reasons to be specially concerned about our future are not provided by the fact that it will be our future. Part Four presents puzzles regarding future generations and argues that the moral principles we need when considering future people must take an impersonal form. Parfit’s arguments deeply challenge our understanding of moral ideals and, some believe, the possibility of comparing outcomes. Parfit has three forthcoming manuscripts, tentatively titled Rediscovering Reasons, The Metaphysics of the Self, and On What Matters. His current focus is the normativity of reasons. A reductionist about persons, he is a non-reductionist about reasons. He believes in irreducibily normative beliefs that are in a strong sense true. A realist about reasons for acting and caring, he challenges the views of naturalists, noncognitivists, and constructivists. Parfit contends that internalists conflate normativity with motivating force, that contrary to the prevalent view that all reasons are provided by desires, no reasons are, and that Kant poses a greater threat to rationalism than Hume. Parfit is Senior Research Fellow of All Souls , Oxford, and a regular visiting professor at both Harvard and New York . Legendary for monograph-length criticisms of book manuscripts, he is editor of the Oxford Ethics Series, whose goal is to make definite moral progress, a goal Parfit himself is widely believed to have attained.

Parmenide: “One of the most important Italian philosophers, if only because Plato dedicated a dialogue to him!” – Grice. a Grecian philosopher, the most influential of the pre-socratics, active in Elea Roman and modern Velia, an Ionian Grecian colony in southern Italy. He was the first Grecian thinker who can properly be called an ontologist or metaphysician. Plato refers to him as “venerable and awesome,” as “having magnificent depth” Theaetetus 183e 184a, and presents him in the dialogue Parmenides as a searching critic  in a fictional and dialectical transposition  of Plato’s own theory of Forms. Nearly 150 lines of a didactic poem by Parmenides have been preserved, assembled into about twenty fragments. The first part, “Truth,” provides the earliest specimen in Grecian intellectual history of a sustained deductive argument. Drawing on intuitions concerning thinking, knowing, and language, Parmenides argues that “the real” or “what-is” or “being” to eon must be ungenerable and imperishable, indivisible, and unchanging. According to a Plato-inspired tradition, Parmenides held that “all is one.” But the phrase does not occur in the fragments; Parmenides does not even speak of “the One”; and it is possible that either a holistic One or a plurality of absolute monads might conform to Parmenides’ deduction. Nonetheless, it is difficult to resist the impression that the argument converges on a unique entity, which may indifferently be referred to as Being, or the All, or the One. Parmenides embraces fully the paradoxical consequence that the world of ordinary experience fails to qualify as “what-is.” Nonetheless, in “Opinions,” the second part of the poem, he expounds a dualist cosmology. It is unclear whether this is intended as candid phenomenology  a doctrine of appearances  or as an ironic foil to “Truth.” It is noteworthy that Parmenides was probably a physician by profession. Ancient reports to this effect are borne out by fragments from “Opinions” with embryological themes, as well as by archaeological findings at Velia that link the memory of Parmenides with Romanperiod remains of a medical school at that site. Parmenides’ own attitude notwithstanding, “Opinions” recorded four major scientific breakthroughs, some of which, doubtless, were Parmenides’ own discoveries: that the earth is a sphere; that the two tropics and the Arctic and Antarctic circles divide the earth into five zones; that the moon gets its light from the sun; and that the morning star and the evening star are the same planet. The term Eleatic School is misleading when it is used to suggest a common doctrine supposedly held by Parmenides, Zeno of Elea, Melissus of Samos, and anticipating Parmenides Xenophanes of Colophon. The fact is, many philosophical groups and movements, from the middle of the fifth century onward, were influenced, in different ways, by Parmenides, including the “pluralists,” Empedocles, Anaxagoras, and Democritus. Parmenides’ deductions, transformed by Zeno into a repertoire of full-blown paradoxes, provided the model both for the eristic of the Sophists and for Socrates’ elenchus. Moreover, the Parmenidean criteria for “whatis” lie unmistakably in the background not only of Plato’s theory of Forms but also of salient features of Aristotle’s system, notably, the priority of actuality over potentiality, the unmoved mover, and the man-begets-man principle. Indeed, all philosophical and scientific systems that posit principles of conservation of substance, of matter, of matter-energy are inalienably the heirs to Parmenides’ deduction. Refs.: H. P.

pars/Totum – Those who are inclined to Grecianisms will use “holism,” but unlike ‘totum,’ ‘holos,’ being from EASTERN Europe, did not develop in Western Europe, whereas ‘totum’ gives us plenty of cognates in Grice’s vernacular, via Anglo-Norman, ‘totality,’ for example. From Grecian ‘holon,’ Latin ‘totum.’ “One of Quine’s dogma of empiricism – the one I and Sir Peter had not the slightest intereset in!” – Grice. Holism is one of a wide variety of theses that in one way or another affirm the equal or greater reality or the explanatory necessity of the whole of some system in relation to its parts. In philosophy, the issues of holism (the word is more reasonably, but less often, spelled ‘wholism’) have appeared Hohenheim, Theophrastus Bombastus von holism 390 4065h-l.qxd 08/02/1999 7:39 AM Page 390 traditionally in the philosophy of biology, of psychology, and especially of the human sciences. In the context of description, holism with respect to some system maintains that the whole has some properties that its parts lack. This doctrine will ordinarily be trivially true unless it is further held, in the thesis of descriptive emergentism, that these properties of the whole cannot be defined by properties of the parts. The view that all properties of the wholes in question can be so defined is descriptive individualism. In the context of explanation, holism with respect to some object or system maintains either (1) that the laws of the more complex cases in it are not deducible by way of any composition laws or laws of coexistence from the laws of the less complex cases (e.g., that the laws of the behavior of people in groups are not deducible by composition laws or laws of coexistence from the laws of solitary behavior), or (2) that all the variables that constitute the system interact with each other. This denial of deducibility is known also as metaphysical or methodological holism, whereas affirming the deducibility is methodological individualism. In a special case of explanatory holism that presupposes descriptive emergentism, holism is sometimes understood as the thesis that with respect to some system the whole has properties that interact “back” with the properties of its parts. In the philosophy of biology, any of these forms of holism may be known as vitalism, while in the philosophy of psychology they have been called Gestalt doctrine. In the philosophy of the social sciences, where ‘holism’ has had its most common use in philosophy, the many issues have often been reduced to that of metaphysical holism versus methodological individualism. This terminology reflected the positivists’ belief that holism was non-empirical in postulating social “wholes” or the reality of society beyond individual persons and their properties and relations (as in Durkheim and other, mostly Continental, thinkers), while individualism was non-metaphysical (i.e., empirical) in relying ultimately only on observable properties in describing and explaining social phenomena. More recently, ‘holism’ has acquired additional uses in philosophy, especially in epistemology and philosophy of language. Doxastic or epistemic holism are theses about the “web of belief,” usually something to the effect that a person’s beliefs are so connected that their change on any topic may affect their content on any other topic or, perhaps, that the beliefs of a rational person are so connected. Semantic or meaning holism have both been used to denote either the thesis that the meanings of all terms (or sentences) in a language are so connected that any change of meaning in one of them may change any other meaning, or the thesis that changes of belief entail changes of meaning. Cited by Grice, “In defense of a dogma” “My defense of the other dogma must be left for another longer day” Duhem, Pierre-Maurice-Marie, physicist who wrote extensively on the history and philosophy of science. Like Georg Helm, Wilhelm Ostwald, and others, he was an energeticist, believing generalized thermodynamics to be the foundation of all of physics and chemistry. Duhem spent his whole scientific life advancing energetics, from his failed dissertation in physics a version of which was accepted as a dissertation in mathematics, published as Le potentiel thermodynamique 6, to his mature treatise, Traité d’énergétique 1. His scientific legacy includes the Gibbs-Duhem and DuhemMargules equations. Possibly because his work was considered threatening by the Parisian scientific establishment or because of his right-wing politics and fervent Catholicism, he never obtained the position he merited in the intellectual world of Paris. He taught at the provincial universities of Lille, Rennes, and, finally, Bordeaux. Duhem’s work in the history and philosophy of science can be viewed as a defense of the aims and methods of energetics; whatever Duhem’s initial motivation, his historical and philosophical work took on a life of its own. Topics of interest to him included the relation between history of science and philosophy of science, the nature of conceptual change, the historical structure of scientific knowledge, and the relation between science and religion. Duhem was an anti-atomist or anti-Cartesian; in the contemporary debates about light and magnetism, Duhem’s anti-atomist stance was also directed against the work of Maxwell. According to Duhem, atomists resolve the bodies perceived by the senses into smaller, imperceptible bodies. The explanation of observable phenomena is then referred to these imperceptible bodies and their motions, suitably combined. Duhem’s rejection of atomism was based on his instrumentalism or fictionalism: physical theories are not explanations but representations; they do not reveal the true nature of matter, but give general rules of which laws are particular cases; theoretical propositions are not true or false, but convenient or inconvenient. An important reason for treating physics as nonexplanatory was Duhem’s claim that there is general consensus in physics and none in metaphysics  thus his insistence on the autonomy of physics from metaphysics. But he also thought that scientific representations become more complete over time until they gain the status of a natural classification. Accordingly, Duhem attacked the use of models by some scientists, e.g. Faraday and Maxwell. Duhem’s rejection of atomism was coupled with a rejection of inductivism, the doctrine that the only physical principles are general laws known through induction, based on observation of facts. Duhem’s rejection forms a series of theses collectively known as the Duhem thesis: experiments in physics are observations of phenomena accompanied by interpretations; physicists therefore do not submit single hypotheses, but whole groups of them, to the control of experiment; thus, experimental evidence alone cannot conclusively falsify hypotheses. For similar reasons, Duhem rejected the possibility of a crucial experiment. In his historical studies, Duhem argued that there were no abrupt discontinuities between medieval and early modern science  the so-called continuity thesis; that religion played a positive role in the development of science in the Latin West; and that the history of physics could be seen as a cumulative whole, defining the direction in which progress could be expected. Duhem’s philosophical works were discussed by the founders of twentieth-century philosophy of science, including Mach, Poincaré, the members of the Vienna Circle, and Popper. A revival of interest in Duhem’s philosophy began with Quine’s reference in 3 to the Duhem thesis also known as the Duhem-Quine thesis. As a result, Duhem’s philosophical works were tr. into English  as The Aim and Structure of Physical Theory 4 and To Save the Phenomena 9. By contrast, few of Duhem’s extensive historical works  Les origines de la statique 2 vols., 608, Études sur Léonard de Vinci 3 vols., 613, and Système du monde 10 vols., 359, e.g.  have been tr., with five volumes of the Système du monde actually remaining in manuscript form until 459. Unlike his philosophical work, Duhem’s historical work was not sympathetically received by his influential contemporaries, notably George Sarton. His supposed main conclusions were rejected by the next generation of historians of science, who presented modern science as discontinuous with that of the Middle Ages. This view was echoed by historically oriented philosophers of science who, from the early 0s, emphasized discontinuities as a recurrent feature of change in science  e.g. Kuhn in The Structure of Scientific Revolutions 2. 


parsing: the process of determining the syntactic (strictly para-tactic) structure of a sentence according to the theorems of a given system, say Gricese – or System G.This is to be distinguished from the generally simpler task of recognition, which is merely the determination of whether or not a given string is well-formed grammatical. In general, many different parsing strategies can be employed for grammars of a particular type, and a great deal of attention has been given to the relative efficiencies of these techniques. The most thoroughly studied cases center on the contextfree phrase structure grammars, which assign syntactic structures in the form of singly-rooted trees with a left-to-right ordering of “sister” nodes. Parsing procedures can then be broadly classified according to the sequence of steps by which the parse tree is constructed: top-down versus bottom-up; depth-first versus breadthfirst; etc. In addition, there are various strategies for exploring alternatives agendas, backtracking, parallel processing and there are devices such as “charts” that eliminate needless repetitions of previous steps. Efficient parsing is of course important when language, whether natural or artificial e.g., a programming language, is being processed by computer. Human beings also parse rapidly and with apparently little effort when they comprehend sentences of a natural language. Although little is known about the details of this process, psycholinguists hope that study of mechanical parsing techniques might provide insights. Refs.: H. P. Grice, “Parsing in Gricese.”

partition: Grice: “the division of a set into mutually exclusive and jointly exhaustive subsets (e. g., ‘philosopher’ and ‘non-philosopher’ – whether we define ‘philosopher’ as engaged in philosophical exploration,’ or ‘addicted to general reflections about his life.’ -- Derivatively, ‘partition’ can mean any set P whose members are mutually exclusive and jointly exhaustive subsets of set S. Each subset of a partition P is called a partition class of S with respect to P. Partitions are intimately associated with equivalence relations, i.e. with relations that are transitive, symmetric, and reflexive. Given an equivalence relation R defined on a set S, R induces a partition P of S in the following natural way: members s1 and s2 belong to the same partition class of P if and only if s1 has the relation R to s2. Conversely, given a partition P of a set S, P induces an equivalence relation R defined on S in the following natural way: members s1 and s2 are such that s1 has the relation R to s2 if and only if s1 and s2 belong to the same partition class of P. For obvious reasons, then, partition classes are also known as equivalence classes. Refs.: H. P. Grice, “My love for Venn.”

passeri: genua: essential Italian philosopher. Marco Antonio Passeri (anche noto come Gènua) (Padova, 1491 – Padova, 1563) è stato un filosofo italiano, appartenente all'Averroismo attivo nel periodo del Rinascimento. Figlio di Niccolò Passeri, professore di medicina all'Università di Padova morto nel 1522, Marco Antonio fu egli stesso dal 1517 professore nell'università patavina nella cattedra di filosofia.  Autore di commentarii ad alcune opere di Aristotele, in particolare al De Anima e alla Fisica, tentò di dimostrare la perfetta convergenza fra le idee di Averroè e di Simplicio sulla dottrina dell'unità dell'intelletto.  Marco Antonio Passeri fu insegnante e zio del filosofo rinascimentale Giacomo Zabarella.  Opere Aristotelis De anima libri tres, cum Auerrois commentariis et antiqua tralatione suae integritati restituta.

paternalism, interference with the liberty or autonomy of another person, with justifications referring to the promotion of the person’s good or the prevention of harm to the person. More precisely, A acts paternalistically toward B iff A is B’s father or P acts with the intent of averting some harm or promoting some benefit for Q; and P acts contrary to or is indifferent to the current preferences, desires or values of his ‘son;’ and P’s act is a limitation on his ‘son’ autonomy or liberty. The presence of both autonomy and liberty in the lasst clause is to allow for the fact that lying to someone is not clearly an interference with liberty. Notice that one can act ‘paternalistically’ by telling people the truth as when a doctor insists that a patient know the exact nature of her illness, contrary to her wishes. Note also that the definition does not settle any questions about the legitimacy or illegitimacy of paternalistic interventions. Typical examples of paternalistic actions are laws requiring motorcyclists to wear helmets; court orders allowing physicians to transfuse Jehovah’s Witnesses against their wishes; deception of a patient by physicians to avoid upsetting the patient; civil commitment of persons judged dangerous to themselves; and laws forbidding swimming while lifeguards are not on duty. Soft weak paternalism is the view that paternalism is justified only when a ‘father’ is acting non-voluntarily or one needs time to determine whether his ‘son’ is acting voluntarily or not. Hard strong paternalism is the view that paternalism is sometimes justified even when the person being interfered with is acting voluntarily. The analysis of the term is relative to some set of problems. If one were interested in the organizational behavior of large corporations, one might adopt a different definition than if one were concerned with limits on the state’s right to exercise coercion. The typical normative problems about paternalistic action are whether, and to what extent, the welfare of individuals may outweigh the need to respect their desire to lead their own lives and make their own decisions even when mistaken. Mill is the best example of a virtually absolute ANTI-paternalism, at least with respect to the right of the state to act paternalistically. Mill (whose father was a devil) argues that unless we have reason to believe that my ‘son’ is not acting voluntarily, as in the case of a man walking across a bridge that, unknown to him, is about to collapse, we ought to allow an adult son the freedom to act even if his act is harmful to himself.

Patrologia series latina -- patristic authors – Includes Aelwhinec, Grice’s favourite speculative grammarian. Migne’s Patrologia – Series Latina -- patrologia latina -- also called church fathers – “the implicature is that one can have more than one father, I suppose.” – Grice. a group of philosophers originally so named because they were considered the “patres” of the Church of England to which Grice belongs.. The term “patries ecclesiae” is now used more broadly to designate philosophers, orthodox or heterodox, who were active in the first six centuries or so of the Christian era. The chronological division is quite flexible, and it is regularly moved several centuries later for particular purposes. Moreover, the study of these philosophers has traditionally been divided variously, of which the principal ones are of course, Grecian and Roman. The often sharp divisions among patristic scholarships are partly a reflection of the different histories of the regional churches, partly a reflection of the sociology of cholarship. The patristic period in Grecian is usually taken as extending from the writers after the so-called “New” Testament (such as “Paul,” after whom Grice was named – he was named “Herbert” after a Viking ancestor), to such figures as Maximus the Confessor or John of Damascus. The period is traditionally divided around the Council of Nicea. PreNicean Grecian authors of importance to the history of philosophy include Irenaeus, Clement of Alexandria, and Origen. Important Nicean and post-Nicean authors include Athanasius; the Cappadocians, i.e., Gregory of Nazianzum, Basil of Cesarea  and his brother, Gregory of Nyssa, and John Chrysostom. Philosophical topics and practices are constantly engaged by these Grecian authors. Justin Martyr e.g., describes his conversion to Christianity quite explicitly as a transit through lower forms of philosophy into the true philosophy. Clement of Alexandria, again, uses the philosophic genre of the protreptic and a host of ancient texts to persuade his pagan readers that they ought to come to Christianity as to the true wisdom. Origen devotes his Against Celsus to the detailed rebuttal of one pagan philosopher’s attack on Christianity. More importantly, if more subtly, the major works of the Cappadocians appropriate and transform the teachings of any number of philosophic authors  Plato and the Neoplatonists in first place, but also Aristotle, the Stoics, and Galen. The Roman church came to count four post-Nicean authors as its chief teachers in the “Patrologia latina”: Ambrose Jerome,  and Gregory the Great. Other Roman authors of philosophical interest include Tertulliano,  Lactanzio, Mario Vittorino, and Hilary of Poitiers. The Roman patristic period is typically counted roughly from Tertulliano (of “Credo quia assudrdo” infame) to Boezio, the translator of Porfirio’s Isagoge.. The Roman ‘fathers’ share with their Grecian contemporaries a range of relations to the pagan philosophic schools, both as rival institutions and as sources of useful teaching. Tertullian’s Against the Nations and Apology, e.. g., take up pagan accusations against Christianity and then counterattack a number of pagan beliefs, including philosophical ones. By contrast, the writings of Mario Vittorino, Ambrose, and Augustine enact transformations of philosophic teachings, especially from the Neoplatonists. Because philosophical erudition is generally less hellenistic among the Romans as among the hellenes, they are, fortunately to us, both more eager to accept philosophical doctrines and freer in improvising variations on them. 

patrizi: Grice, “His surname is Patrizi, his first name is Francesco – he was born on an island, but taught at Rome -- important Italian philosopher, “even if he disliked Aristotle.” “He shouldn’t count as Italian since he is of Croatian descent, but he lived in what was then part of the republic of Venice, so that’s something.” – Grice . Francesco Patrizi[1] (in latino: Franciscus Patricius, in croato: Franjo Petriš/Frane Petrić; Cherso, Croazia, 25 aprile 1529 – Roma, 6 febbraio 1597) è stato un filosofo e scrittore italiano, di orientamento neoplatonico. Non sono molte le notizie sulla sua vita; gli spunti tratti dalla sua opera furono noti ai suoi successori solo attraverso altri pensatori. Della sua opera si inizia a discutere solo verso l'Ottocento. Nel 1538 era già imbarcato su una nave al comando dello zio Giovanni Giorgio Patrizi; dopo aver studiato a Cherso con Petruccio da Bologna, nel 1544 fu a Venezia, dove studiò grammatica con Andrea Fiorentino, passando poi a Ingolstadt, sotto la protezione del cugino, il luterano Mattia Flacio Illirico.  Nel 1547 era a Padova per studiare filosofia con Bernardino Tomitano, Marco Antonio Passeri, detto "Il Genua", Lazzaro Bonamico e Francesco Robortello; qui fu presidente della Congrega degli Studenti Dalmati e pubblicò i suoi primi scritti.  In una tarda lettera, indirizzata il 12 gennaio 1587 all'amico Baccio Valori, scrisse che a Padova aveva «trovato un Xenofonte greco e latino, senza niuna guida o aiuto, si mise nella lingua greca, di che havea certi pochi principi in Inghilstat, e fece tanto profitto che a principio di novembre e di studio ardì di studiare e il testo di Aristotile e i commentatori sopra la Loica greci. Andò ad udir il Tomitano, famoso loico, ma non gli pose mai piacere, senza saper dire perché, onde studiò loica da sé. L'anno seguente entrò alla filosofia di un certo Alberto e del Genoa e né anco questi gli poterono piacere, onde studiò da sé. In fin di studio udì il Monte medico, e gli piacque per il metodo di trattar le cose, e così Bassiano Lando, di cui fu scolare mentre stette in istudio. E fra tanto, sentendo un frate di S. Francesco sostentar conclusioni platoniche, se ne innamorò, e fatto poi seco amicizia dimandogli che lo inviasse per la via di Platone. Gli propose come per via ottima la Teologia del Ficino, a che si diede con grande avidità: E tale fu il principio di quello che poi sempre ha seguitato».  A Venezia nel 1553 pubblicò la Città felice, il Dialogo dell'Honore, il Discorso sulla diversità dei furori poetici e le Lettere sopra un sonetto di Petrarca. Alla morte del padre nel 1554 tornò a Cherso per occuparsi dell'eredità e vi rimase per quattro anni.  Tornato in Italia, intenzionato ad entrare nella corte del duca di Ferrara Ercole II d'Este, gli presentò il suo poema, Eridano, scritto negli innovativi versi martelliani tredecasillabi, senza tuttavia ottenere il successo sperato. Passato allora a Venezia, sotto il patronato di Giorgio Contarini, fondò con il poeta Bernardo Tasso, il padre di Torquato, l'Accademia della Fama e scrisse i dieci Dialoghi della Historia nel 1560 e nel 1562 i dieci Dialoghi della Retorica.  Mandato a Cipro per curare gli interessi del Contarini, si diede al commercio e all'acquisto di manoscritti greci e si trovò a dover anche partecipare alla guerra turco-veneziana, imbarcato nella flotta comandata da Andrea Doria. Passato al servizio dell'arcivescovo di Cipro Filippo Mocenigo, nel 1568 ritornò in Italia, e si stabilì a Padova, precettore di Zaccaria, nipote del Mocenigo e scrivendo le Discussioni peripatetiche il cui primo volume fu pubblicato nel 1571 e interamente nel 1581 a Basilea, dedicate a Zaccaria Mocenigo. Conquistata Cipro dai turchi, perdette il patrimonio investito nell'isola; vendette allora i manoscritti greci a Filippo II di Spagna e si trovò a dovere chiedere aiuto ad amici ai quali dedicò la sua Amorosa filosofia.  Dal 1577 al 1592 insegnò filosofia nell'università di Ferrara, e fu membro dell'Accademia della Crusca nel 1587, continuando a pubblicare scritti filosofici, letterari, di strategia militare, di ottica, d'idraulica, di botanica; nel 1581 pubblicò le Discussioni peripatetiche, nel 1585 il Parere in difesa di Ludovico Ariosto, nel 1586 il Della Poetica, ove sostenne la superiorità della lingua volgare sul latino, nel 1587 la Nuova geometria dedicata a Carlo Emanuele I di Savoia, la Philosophia de rerum natura e nel 1591 la Nova de universis philosophia, che fu temporaneamente messa all'Indice dal Sant'Uffizio, per essere poi rimossa in seguito alle correzioni fatte dello stesso Patrizi.  Nel 1592 l'amico papa Clemente VIII lo nominò professore presso lo Studium Urbis. A Roma pubblicò nel 1594 la sua ultima opera, i Paralleli militari. Fu anche membro della confraternita di San Girolamo di Roma, cui potevano accedere "illirici, dalmati e schiavoni".  È sepolto nella chiesa romana di Sant’Onofrio al Gianicolo, nella stessa tomba di Torquato Tasso. Le Discussiones peripateticae libri XV esaminano la tradizione aristotelica, confrontandola con quella presocratica e platonica; immediata è la critica di Aristotele, a partire dalla sua vita: «né i suoi costumi furono così santi, né così magnifiche le sue azioni né così varie le sue azioni da ingenerare ammirazione» (I, 2). Lo rimprovera di aver utilizzato scoperte di altri che tuttavia attaccò polemicamente, senza mostrare alcuna riconoscenza.   Il controverso monumento innalzato di recente a Cherso, dove Francesco Patrizi è ribattezzato Frane Petric. Nel merito, critica l'aristotelismo per aver teorizzato che le cose derivino dalle altre attraverso il principio dei contrari; per il Patrizi, ogni cose si origina da una simile, non già da una contraria; gli appare più adeguata la filosofia naturalistica presocratica, a differenza dei principi aristotelici che «non hanno nessuna forza, nessun vigore, nessuna capacità di generare e non arrecano alcun contributo alla generazione di nessuna cosa. A che serve infatti la freddezza al legno per riscaldare o bruciare col fuoco? Che cosa la privazione della forma serve per produrre forma?» (IV, 1).  Nell'opera, il Patrizi fa sfoggio di molta erudizione con uno stile che si compiace di non poca retorica, così dispiacendo al Bruno che la definì "sterco di pedanti". Ma apprezzerà invece la successiva Nova de Universis philosophia, del 1591, il cui titolo completo è Nova de Universis philosophia, libris quinquaginta comprehensa: in qua Aristotelico methodo non per motum, sed per lucem et lumina ad primam causam ascenditur. Deinde nova quidam et peculiari methodo tota in contemplationem venit divinitas. Postremo methodo platonico rerum universitas a conditore Deo deducitur. Fu pubblicata con l'aggiunta degli oracoli di Zoroastro, Ermete Trismegisto, Asclepio, e della Theologia Aristotelis, pubblicata in un'edizione romana nel 1519.  È divisa in quattro parti, la "Panaugia" o della luce, la "Panarchia" o del principio delle cose, la "Pampsichya" o dell'animae la "Pancosmia" o del mondo. Nella prima espone la teoria della luce che, proveniente da Dio, «semplicissima tra le cose, non è duplice, sicché in essa vi è forma e materia. Unica, è a se stessa materia e forma» e si diffonde, con il calore e la materia fluida – il primaevus fluor - per lo spazio che, come essa, è infinito; infatti, se la luce è infinita, anche lo spazio deve essere infinito e così il mondo: «se lo spazio contiene tutto e così pure il mondo, mondo e spazio saranno lo stesso per capacità e determinazione locale. Dunque lo spazio è infinito sicché anche il mondo sarà infinito».  Continua la sua polemica antiaristotelica, sostenendo che la dottrina cristiana si può ricavare dagli stessi dialoghi platonici e la teologia cristiana è già presente in Plotino. Già i primi Padri della Chiesa «vedendo che con pochi mutamenti i platonici potevano divenire facilmente cristiani, anteposero Platone e i platonici a ogni altro e nominarono Aristotele solo con infamia. Ma quasi quattrocento anni fa i teologi scolastici si sono comportati in modo opposto fondando la fede sull'empietà aristotelica. Li scusiamo, perché non poterono conoscere i platonici, non conoscendo il greco, ma non li scusiamo per aver cercato di fondare la fede sull'empietà»[2]. Opere: Al molto magico et magnanimo m.

peano: important Italian philosopher. Peano’s postulates, also called Peano axioms, a list of assumptions from which the integers can be defined from some initial integer, equality, and successorship, and usually seen as defining progressions. The Peano postulates for arithmetic were produced by G. Peano in 9. He took the set N of integers with a first term 1 and an equality relation between them, and assumed these nine axioms: 1 belongs to N; N has more than one member; equality is reflexive, symmetric, and associative, and closed over N; the successor of any integer in N also belongs to N, and is unique; and a principle of mathematical induction applying across the members of N, in that if 1 belongs to some subset M of N and so does the successor of any of its members, then in fact M % N. In some ways Peano’s formulation was not clear. He had no explicit rules of inference, nor any guarantee of the legitimacy of inductive definitions which Dedekind established shortly before him. Further, the four properties attached to equality were seen to belong to the underlying “logic” rather than to arithmetic itself; they are now detached. It was realized by Peano himself that the postulates specified progressions rather than integers e.g., 1, ½, ¼, 1 /8, . . . , would satisfy them, with suitable interpretations of the properties. But his work was significant in the axiomatization of arithmetic; still deeper foundations would lead with Russell and others to a major role for general set theory in the foundations of mathematics. In addition, with O. Veblen, T. Skolem, and others, this insight led in the early twentieth century to “non-standard” models of the postulates being developed in set theory and mathematical analysis; one could go beyond the ‘. . .’ in the sequence above and admit “further” objects, to produce valuable alternative models of the postulates. These procedures were of great significance also to model theory, in highlighting the property of the non-categoricity of an axiom system. A notable case was the “non-standard analysis” of A. Robinson, where infinitesimals were defined as arithmetical inverses of transfinite numbers without incurring the usual perils of rigor associated with them.  Giuseppe Peano (Spinetta di Cuneo, 27 agosto 1858 – Cavoretto, 20 aprile 1932) è stato un matematico, logico e glottoteta italiano. Fu l'ideatore del latino sine flexione, una lingua ausiliaria internazionale derivata dalla semplificazione del latino classico. Giuseppe Peano nacque il 27 agosto 1858 in una modesta fattoria chiamata "Tetto Galant" presso la frazione di Spinetta di Cuneo. Fu il secondogenito di Bartolomeo Peano e Rosa Cavallo; sette anni prima era nato il fratello maggiore Michele e successivamente nacquero Francesco, Bartolomeo e la sorella Rosa. Dopo un inizio estremamente difficile (doveva ogni mattina fare svariati chilometri prima di raggiungere la scuola), la famiglia si trasferì a Cuneo. Il fratello della madre, Giuseppe Michele Cavallo, accortosi delle sue notevoli capacità intellettive, lo invitò a raggiungerlo a Torino, dove continuò i suoi studi presso il Liceo classico Cavour. Assistente di Angelo Genocchi all'Università di Torino, divenne professore di calcolo infinitesimale presso lo stesso ateneo a partire dal 1890.[1]  Vittima della sua stessa eccentricità, che lo portava ad insegnare logica in un corso di calcolo infinitesimale, fu più volte allontanato dall'insegnamento a dispetto della sua fama internazionale, perché "più di una volta, perduto dietro ai suoi calcoli, [..] dimenticò di presentarsi alle sessioni di esame"[2].  Ricordi del grande matematico (e non solo della vita familiare) sono raccontati con grazia e ammirazione nel romanzo biografico Una giovinezza inventata della pronipote Lalla Romano, scrittrice e poetessa.  Il 24 dicembre del 1885 aderì alla massoneria, iniziato nella loggia Dante Alighieri di Torino guidata dal socialista Giovanni Lerda.[3]  Morì nella sua casa di campagna a Cavoretto, presso Torino, per un attacco di cuore che lo colse nella notte.  Il matematico piemontese fu capostipite di una scuola di matematici italiani, tra i quali possiamo annoverare Giovanni Vailati, Filiberto Castellano, Cesare Burali-Forti, Alessandro Padoa, Giovanni Vacca, Mario Pieri e Tommaso Boggio [4]. Peano precisò la definizione del limite superiore e fornì il primo esempio di una curva che riempie una superficie (la cosiddetta "curva di Peano", uno dei primi esempi di frattale), mettendo così in evidenza come la definizione di curva allora vigente non fosse conforme a quanto intuitivamente si intende per curva.  Da questo lavoro partì la revisione del concetto di curva, che fu ridefinito da Camille Jordan (1838 – 1932) (curva secondo Jordan).  Fu anche uno dei padri del calcolo vettoriale insieme a Tullio Levi-Civita. Dimostrò importanti proprietà delle equazioni differenziali ordinarie e ideò un metodo di integrazione per successive approssimazioni.  Sviluppò il Formulario mathematico, scritto dapprima in francese e nelle ultime versioni in interlingua, come chiamava il suo latino sine flexione, contenente oltre 4000 tra teoremi e formule, per la maggior parte dimostrate.  Come logico dette un eccezionale contributo alla logica delle classi, elaborando un simbolismo di grande chiarezza e semplicità. Diede una definizione assiomatica dei numeri naturali, i famosi "assiomi di Peano" che vennero poi ripresi da Russell e Whitehead nei loro Principia Mathematica per sviluppare la teoria dei tipi.  I contributi di Giuseppe Peano sulla logica furono osservati con molta attenzione nel 1900 dal giovane Bertrand Russell, mentre i contributi di aritmetica e di teoria dei numeri furono osservati con molta attenzione da Giovanni Vailati, il quale sintetizzava in Italia il passaggio tra l'esame delle questioni fondamentali e l'applicazione di metodiche di analisi del linguaggio scientifico, tipica degli studi logici e matematici, e anche specificava gli interessi di storia della scienza, allargando la prospettiva anche agli studi sociali. Per questo Peano ebbe dei contatti molto stretti con il mondo degli studiosi di logica e di filosofia del linguaggio nonché gli studiosi di scienze sociali empiriche (Cfr. Guglielmo Rinzivillo, Giuseppe Peano, Giovanni Vailati. Contributi invisibili in Guglielmo Rinzivillo, Una Epistemologia senza storia, Roma Nuova Cultura, 2013, II, p. 165 e sg. - ISBN 978-88-6812-222-5).  Ebbe ampi riconoscimenti negli ambienti filosofici più aperti alle esigenze e alle implicazioni critiche della nuova logica formale. Era affascinato dall'ideale leibniziano della lingua universale e sviluppò il "latino sine flexione", lingua con la quale cercò di tenere i suoi interventi ai congressi internazionali di Londra e Toronto[4].  Tale lingua fu concepita per semplificazione della grammatica ed eliminazione delle forme irregolari, applicandola a un numero di vocaboli "minimo comune denominatore" tra quelli principalmente di origine latina e greca rimasti in uso nelle lingue moderne. Uno dei grandi meriti dell'opera di Peano sta nella ricerca della chiarezza e della semplicità. Contributo fondamentale che gli si riconosce è la definizione di notazioni matematiche entrate nell'uso corrente, come, per esempio, il simbolo di appartenenza (es: x A) o il quantificatore esistenziale "".  Tutta l'opera di Peano verte sulla ricerca della semplificazione, dello sviluppo di una notazione sintetica, base del progetto del già citato Formulario, fino alla definizione del Latino sine flexione. La ricerca del rigore e della semplicità portarono Peano ad acquistare una macchina per la stampa, allo scopo di comporre e verificare di persona i tipi per la Rivista di Matematica (da lui diretta) e per le altre pubblicazioni. Peano raccolse una serie di note per le tipografie relative alla stampa di testi di matematica, uno per tutti il suo consiglio di stampare le formule su righe isolate, cosa che ora viene data per scontata, ma che non lo era ai suoi tempi[5]. Onorificenze: 1905 - Cavaliere dell'Ordine della Corona d'Italia 1917 - Ufficiale della Corona 1921 - Commendatore della corona L'asteroide 9987 Peano è stato battezzato così in suo onore.  Il dipartimento di Matematica della facoltà di Scienze Matematiche, Fisiche e Naturali dell'Università degli Studi di Torino è a lui dedicato[6].  Molti licei scientifici in Italia portano il suo nome, come ad esempio a Roma, Cuneo, Tortona, Monterotondo, Cinisello Balsamo (fino al 2013)[7] o Marsico Nuovo, così come la scuola elementare di Tetto Canale, vicina alla sua città natale. Opere Giuseppe Peano, Aritmetica generale e algebra elementare, Torino, Paravia, 1902.

pearsianism – after D. F. Pears, one of Grice’s collaborators in the Play Group. “In them days, we would never publish, since the only philosophers we were interested in communicating with we saw at least every Saturday!” – With D. F. Pears, and J. F. Thomson, H. P. Grice explored topics in the philosophy of action and ‘philosophical psychology.’ Actually, Grice carefully writes ‘philosophy of action.’ Why? Well, because while with Pears and Thomson he explored toopics like ‘intending’ and ‘deciding,’ it was always with a vew towards ‘acting,’ or ‘doing.’  Grice is very clear on this, “even fastidiously so,” as Blackburn puts it. In the utterance of an imperative, or an intention, which may well be other-directed, the immediate response or effect in your co-conversationalist is a ‘recognition,’ i. e. what Grice calls an ‘uptake,’ some sort of ‘understanding.’ In the case of these ‘desiderative’ moves, the recognition is that the communicator WILLS something. Grice uses a ‘that’-clause attached to ‘will,’ so that he can formulate the proposition “p” – whose realization is in question. Now, this ‘will’ on the part of the ‘communicator’ needs to be ‘transmitted.’ So the communicator’s will includes his will that his emissee will adopt this will. “And eventually act upon it!” So, you see, while it looks as if Pears and Thomson and Grice are into ‘philosophical psychology,’ they are into ‘praxis.’ Not alla Althuser, but almost! Pears explored the idea of the conversational implicaturum in connection, obviously, with action. There is a particular type of conditional that relates to action. Grice’s example, “If I COULD do it, I would climb Mt. Everest on hands and knees.”  Grice and Pears, and indeed Thomson, analysed this ‘if.’ Pears thinks that ‘if’ conversationally implicates ‘if and only if.’ Grice called that “Perfecct pears.”

pelagianism: or as Grice preferred, Pelagusianism --. the doctrine in Christian theology that, through the exercise of free will, human beings can attain moral perfection. A broad movement devoted to this proposition was only loosely associated with its eponymous leader. Pelagius c.354c.425, a lay theologian from Britain or Ireland, taught in Rome prior to its sacking in 410. He and his disciple Celestius found a forceful adversary in Augustine, whom they provoked to stiffen his stance on original sin, the bondage of the will, and humanity’s total reliance upon God’s grace and predestination for salvation. To Pelagius, this constituted fatalism and encouraged moral apathy. God would not demand perfection, as the Bible sometimes suggested, were that impossible to attain. Rather grace made the struggle easier for a sanctity that would not be unreachable even in its absence. Though in the habit of sinning, in consequence of the fall, we have not forfeited the capacity to overcome that habit nor been released from the imperative to do so. For all its moral earnestness this teaching seems to be in conflict with much of the New Testament, especially as interpreted by Augustine, and it was condemned as heresy in 418. The bondage of the will has often been reaffirmed, perhaps most notably by Luther in dispute with Erasmus. Yet Christian theology and practice have always had their sympathizers with Pelagianism and with its reluctance to attest the loss of free will, the inevitability of sin, and the utter necessity of God’s grace.

pera: important Italian philosopher. Marcello Pera (Lucca, 28 gennaio 1943) è un filosofo, politico e accademico italiano, senatore per Forza Italia e Popolo della Libertà dal 1996 al 2013, e Presidente del Senato nella XIV Legislatura. Il 12 novembre 2018 è stato nominato presidente del Comitato storico-scientifico per gli anniversari di interesse nazionale istituito presso la Presidenza del Consiglio dei Ministri. Diplomatosi in ragioneria all'Istituto "F. Carrara" di Lucca nel 1962, lavora prima alla Banca Toscana e poi alla Camera di Commercio di Lucca. Quindi decide di studiare filosofia. Si laurea all'Università di Pisa nel 1972, con 110 su 110 e lode.  Carriera accademica Incoraggiato dal suo maestro Francesco Barone, inizia la carriera accademica nel 1976 come incaricato di Filosofia della scienza a Pisa. In seguito diventa professore straordinario di Filosofia teoretica a Catania (1989-1992) e ordinario di Filosofia della scienza all'Università di Pisa (1992). In questi anni viene presentato da Lucio Colletti al direttore editoriale della casa editrice Laterza, Enrico Mistretta, iniziando subito una intensa attività di consulenza editoriale per la filosofia della scienza. Con questa Casa editrice pubblica anche i suoi primi importanti libri scientifici, allontanandosi dalle posizioni ideologiche dell'estrema sinistra per accostarsi insieme a Lucio Colletti al dibattito culturale allora presente nel Partito Socialista Italiano.  Iniziato alla politica dallo stesso Lucio Colletti, trasmigra con lui e altri intellettuali nel neonato partito di Forza Italia fondato da Silvio Berlusconi. Comincia qui una nuova fase, in cui si è distinto come saggista per l'attività a favore di un avvicinamento della politica alla religione cattolica[1]. Convinto che le libertà civili e politiche, lungi dall'essere fondate sulla relatività delle nostre conoscenze, debbano ricondursi invece alla dignità intrinseca della persona umana, che permane quale che sia la verità delle convinzioni di ciascuno, ha più volte rilevato come sia sbagliato fare del relativismo culturale il fondamento della società liberale. Questa, secondo Pera, ha potuto sorgere piuttosto grazie a quel terreno fertile rappresentato dai principi della religione cristiana. Al tempo, Pera si dichiarava ateo e non credente, venendo pertanto annoverato tra gli atei devoti.[2].  Nel 2001, eletto in Parlamento tra le file di Forza Italia, ascese alla seconda carica dello Stato, la presidenza del Senato, che ha ricoperto fino alla fine della legislatura. Pera è stato collaboratore dei quotidiani “Corriere della Sera”, “Il Messaggero”, “La Stampa” e dei settimanali “L'Espresso” e “Panorama”.  Studi di Filosofia della scienza  Karl Popper insieme a Melitta Mew e Marcello Pera a Kenley (Regno Unito), nel 1986. Il filosofo Marcello Pera ha svolto un'intensa attività di ricerca nel campo della filosofia della scienza a livello internazionale[3]. Il suo primo saggio filosofico di rilievo del 1978 riguarda il metodo scientifico e l'induzione. Pera ha poi concentrato i suoi studi filosofici su Karl Popper. Corrispondente del filosofo austriaco teorico della "società aperta", Marcello Pera è uno dei suoi massimi studiosi italiani.[4]. Su di lui ha scritto l'opera Popper e la scienza su palafitte (1981).  Prima di scrivere il libro, pubblicò alcuni articoli divulgativi, inserendosi in un vasto movimento critico, su "L'Espresso", dedicati ai filosofi che avevano tentato di confutare Karl Marx, il primo dei quali fu dedicato a Popper. Ulteriori studi di Pera furono dedicati alle teorie sui metodi di ricerca del filosofo scozzese David Hume e ai metodi induttivi e scientifici del Settecento: nel 1982 pubblicò i due saggi "Hume, Kant e l'induzione" e "Apologia del metodo". Nel 1986 Pera sviluppò ricerche sui primi studi di elettricità compiuti nel settecento da Alessandro Volta e da Luigi Galvani[5]. Il testo fondamentale di Marcello Pera "Popper e la scienza su palafitte" del 1982 contiene un'analisi dettagliata delle posizioni di numerosi filosofi europei sul rapporto tra scienza e filosofia, in particolare di Francesco Bacone, David Hume, Immanuel Kant, Karl Popper, Thomas Kuhn, Imre Lakatos ed altri studiosi. Il significato del termine "scienza su palafitte" è un ironico riferimento al fatto che, come le palafitte dell'uomo preistorico, la scienza contemporanea (in particolare la teoria della relatività e la fisica atomica) non sono fondate su basi solide come la roccia, ma sono soggette a frequenti modifiche e revisioni, a seguito della scoperta di nuove particelle, di nuovi fenomeni, o di nuove leggi fisiche che in parte modificano quelle precedenti della fisica classica.  Il saggio di Pera inizia con una celebre citazione di Popper sull'evoluzione delle teorie scientifiche, secondo la quale la scienza non poggerebbe su fondamenti immutabili, ma su principi che possono essere oggetto di ulteriori analisi ed approfondimenti.[6]. Come Popper, anche Pera ritiene che le teorie scientifiche abbiano una validità limitata a un determinato contesto: secondo questo orientamento le teorie scientifiche sono parzialmente modificabili nel tempo. Fra le revisioni di sistemi scientifici studiate da Pera vi è la rivoluzione scientifica, convenzionalmente iniziata con Niccolò Copernico e conclusasi con l'opera di Isaac Newton, che ha reso obsolete la fisica aristotelica e tolemaica. Sono poi analizzate le teorie elettromagnetiche, a partire dalle prime formulazioni empiriche di Alessandro Volta e Luigi Galvani fino alle teorie fisico-matematiche di James Clerk Maxwell. Infine, nel corso del Novecento si sono avuti rinnovamenti significativi della fisica classica, che hanno portato alla fisica moderna con le teorie della relatività (ristretta e generale) di Einstein e la meccanica quantistica. Pera analizza l'evoluzione di queste teorie scientifiche in relazione a quella del metodo scientifico, basato su procedimenti razionali ed induttivi.  Metodo scientifico ed induzione Marcello Pera ha sostenuto una posizione intermedia fra il pensiero di Karl Popper che non accetta l'induzione, e quella di altri filosofi che convalidano il metodo scientifico basato sull'induzione, definito da David Hume, uno dei maggiori esponenti dell'empirismo nel settecento. Pera condivide il contributo di Popper e degli altri esponenti del Circolo di Vienna alla filosofia della scienza del XX secolo, pur cercando di superare certe loro posizioni che considera troppo radicali, rivalutando così un certo ruolo dell'induzione nella ricerca scientifica. Sulle differenze fra la posizione di Pera e di Popper riguardo al metodo induttivo, si veda[7].  Altri saggi sui metodi scientifici Marcello Pera ha dedicato numerosi articoli su riviste specializzate a temi di Filosofia della scienza e sul Metodo scientifico, tra cui:  Pera M., "Induzione, scandalo dell'empirismo", in "Introduzione a Feigl", (1979). Pera M., "La scoperta scientifica: congetture selvagge o argomentazioni induttive?", in "Medicina nei secoli", XVI, n.1, pp.51-70, (1979). Pera M., "È scientifico il programma scientifico di Marx?", in "Studium", 75, 4, pp.441-463, (1979). Pera M., "Principi a priori e canoni di razionalità scientifica", in "Physis", XXII, 2, pp.261-278, (1980). Pera M., "Le teorie come metafore e l'induzione", in "Physis", XXII, 3-4, (1980). Pera M., "Inductive Method and Scientific Discovery", in collaborazione con Grmek, Cohen, Cimino, (1980). Sulla storia della scienza ha pubblicato:  Pera M., "La rana ambigua: la controversia sull'elettricità animale tra Galvani e Volta", il Mulino (1986) - Edizione inglese: Princeton University Press (1991). Pera M., "Scienza e retorica", Laterza (1992) - Edizione inglese: "The Discourses of Science", The University of Chicago Press (1994). Attività politica Attività politica nel PSI Negli anni ottanta e nei primi anni novanta, Marcello Pera fa parte del Partito Socialista Italiano.  A ricordo del suo periodo di vicinanza al Partito Socialista, nel 2004 Pera si è recato ad Hammamet in visita alla tomba di Bettino Craxi, che ha definito un "patrimonio della Repubblica", che appartiene alla "storia della sinistra italiana"[8]. Nel 1994 durante la stagione di Mani Pulite, Marcello Pera si impegnò sulla questione morale con impeto giustizialista; espresse severe critiche alla corruzione della politica, schierandosi senza riserve dalla parte dei magistrati di Milano.  Pera si impegnò anche nell'area laica, nel movimento referendario di Massimo Severo Giannini con la lista Sì Referendum[9]. Viene inoltre ingaggiato come commentatore dal quotidiano La Stampa, per il quale tra 1992 e 1993 formula diverse critiche alla corruzione politica in Italia e si esprime nei seguenti termini:  «Come alla caduta di altri regimi, occorre una nuova Resistenza, un nuovo riscatto e poi una vera, radicale, impietosa epurazione [...] Il processo è già cominciato e per buona parte dell'opinione pubblica già chiuso con una condanna» (La Stampa, 19 luglio 1992) «I partiti devono retrocedere e alzare le mani [...] subito e senza le furbizie che accompagnano i rantoli della loro agonia. Questo sì sarebbe un golpe contro la democrazia: cercare di resistere contro la volontà popolare» (1º febbraio 1993) «Il garantismo, come ogni ideologia preconcetta, è pernicioso» (29 marzo 1993). «I giudici devono andare avanti. Nessuno chiede che gli inquisiti eccellenti abbiano un trattamento diverso dagli altri inquisiti» (5 marzo 1993) «No e poi no, onorevole Bossi. Lei deve chiedere scusa... I giudici fanno il loro dovere... Molti magistrati sono già stati assassinati per aver fatto rispettare la legge... Lei mette in discussione i fondamenti stessi dello Stato di diritto» (24 settembre 1993) *«la rivoluzione ha regole ferree e tempi stretti» (26 settembre 1993) «Quei politici che, come Craxi, attaccano i magistrati di Milano, mostrano di non capire la sostanza grave, epocale, del fenomeno» Con Luigi Manconi nel 1995 firmò un appello per l'uso delle droghe leggere[10].  Ancora nel 1994 Pera dichiarò: "Berlusconi è a metà strada tra un cabarettista azzimato e un venditore televisivo di stoviglie, una roba che avrebbe ispirato e angosciato il povero Fellini"[11].  Senatore di Forza Italia  Pera nel 1996. Nel 1994 Pera cambia radicalmente schieramento e aderisce a Forza Italia di cui diventa coordinatore nazionale della Convenzione per la riforma liberale. Pera, in questo periodo, si allontana dalle precedenti posizioni giustizialiste temperandole in senso garantista.  Pera iniziò a criticare gli "eccessi" del pool di Milano e Palermo, che arrivò a definire golpisti e invitò D'Alema a «fermare i giudici», indicando nel garantismo una posizione intermedia fra giustizialismo e corruzione, e proponendo la separazione delle carriere e l'obbligatorietà dell'azione penale. Pera polemizzò inoltre con i magistrati di Milano per una vicenda che vedeva coinvolto Paolo Berlusconi nel caso Simec, la società di gestione della discarica di Cerro Maggiore[12].  Alle elezioni politiche italiane del 1996 Pera viene candidato al Senato per Forza Italia nella sua Lucca, ma viene sconfitto all'uninominale dal senatore locale, Patrizio Petrucci dei DS. Viene poi ripescato in quota proporzionale tramite il sistema dei resti ed eletto nel gruppo Forza Italia al Senato, ed è nominato nel 1998 vicepresidente del Gruppo di Forza Italia al Senato.  Assieme a Marco Boato fonda la "Convenzione per la giustizia", un movimento politico "virtuale" che consente il finanziamento pubblico de Il Foglio di Giuliano Ferrara. In Parlamento, Pera si occupa soprattutto dei problemi della Giustizia in Italia: è stato ispiratore della riforma costituzionale sul "giusto processo", approvata nella XIII Legislatura, che ha modificato l'articolo 111 della Costituzione[13].  La Presidenza del Senato (2001-2006)  Il Presidente del Senato Marcello Pera e il Presidente della Camera Pier Ferdinando Casini accolgono papa Giovanni Paolo II al Parlamento italiano, 14 novembre 2002. Nelle elezioni politiche del 2001 vince nel collegio uninominale di Lucca, l'unico della Toscana andato al centro-destra. Viene eletto al primo scrutinio Presidente del Senato della Repubblica, seconda carica dello Stato, che manterrà fino al 2006. Nel suo "Discorso di insediamento al Senato della Repubblica" del 30 marzo 2001 Marcello Pera ha dichiarato:  «Questo è il nucleo della democrazia... Non è soltanto il governo del popolo, la democrazia; non è neppure soltanto il governo delle regole o della legge: è qualcosa di più difficile, ma anche di più esaltante. La democrazia è quel regime di governo che permette a chi si oppone di sostituire pacificamente chi prende le decisioni a nome della maggioranza. Per questo la democrazia o lo strumento della democrazia non è soltanto il voto, ma l'argomentazione, il discorso, il confronto. Per sostituire chi governa, prima di votare occorre confutare e criticare. Allo stesso modo per governare occorre argomentare e convincere»  In quegli anni è Presidente onorario della "Fondazione Magna Carta"[14].  Senatore con Forza Italia (2006-2008) e con il Popolo della Libertà (2008-2013) Lasciata la presidenza del Senato, alle elezioni politiche italiane del 2006 è rieletto senatore nella lista di Forza Italia nel collegio della Emilia Romagna e dal 2007 vice-capogruppo di Forza Italia al Senato[15].  Al seguito della caduta del governo Prodi e delle elezioni politiche italiane del 2008, è stato confermato al Senato come capolista della circoscrizione Lazio per il Popolo della Libertà.  Politica locale in Toscana Marcello Pera ha partecipato anche ad alcuni temi di politica locale, in particolare in Toscana e a Lucca. Inoltre ha svolto un ruolo attivo nell'ambito della Camera di Commercio di Lucca negli anni sessanta e settanta e poi soprattutto nelle istituzioni dell'Università di Pisa negli anni ottanta e novanta. Nel 2005 Marcello Pera ha espresso alcune critiche ai rapporti fra il Comune di Lucca e la Azienda Municipalizzata del Gas; Pera viene quindi accusato in Consiglio comunale dall'allora sindaco Pietro Fazzi (sostenuto da una maggioranza di centrodestra) di essersi intromesso nella gestione amministrativa del Comune. La vicenda verteva su supposte pressioni del senatore per la cessione di quote societarie di Gesam gas, azienda municipalizzata per la somministrazione del gas, ad Enel gas spa. La polemica ha portato allo scioglimento del Consiglio comunale di Lucca e alle dimissioni del sindaco Pietro Fazzi, successivamente espulso dal suo partito[16].  Della vicenda si è interessata anche la Procura di Lucca, che nel 2007 ha archiviato il caso[17]. A settembre 2016 Marcello Pera insieme a Giuliano Urbani ha fondato il Comitato "Liberi Sì" per il Referendum 2016. Questo comitato era molto vicino alle posizioni di Scelta Civica e Alleanza Liberalpopolare-Autonomie, e raccoglieva al suo interno alcune personalità del centrodestra come Giuliano Urbani ed Enzo Ghigo.  In dicembre 2016 il suo nome era tra i papabili come possibile Ministro nel nuovo Governo Gentiloni.  L'avvicinamento al mondo cattolico In passato Marcello Pera si era definito un "non credente"; Pera si è poi avvicinato al pensiero cristiano, accogliendo l'invito di papa Benedetto XVI a vivere "come se Dio esistesse". Dice infatti Pera in Perché dobbiamo dirci cristiani (2008): "Io suggerisco di accettare l'esortazione che il Papa ha fatto ai non credenti: seguire la vecchia formula di Pascal e Kant di vivere ‘come se Dio esistesse’ (velut si Deus daretur)". La frase citata e commentata da Pera è tratta da: Immanuel Kant, Critica della ragion pratica, trad. it. di F. Capra, riveduta da E. Garin, Roma-Bari, Laterza 1979, pag. 157. Pera ritiene che sia una soluzione saggia, perché rende tutti moralmente più responsabili: "Se Dio esiste, ci sono limiti morali alle mie azioni, comportamenti, decisioni, progetti, leggi e così via...". Vedi in proposito il libro di Pera Perché dobbiamo dirci cristiani (2008), al capitolo "Come se Dio esistesse", pagine 54-58, in cui Pera indica due modi di avvicinarsi al cristianesimo: quello della persona fermamente credente e quello della persona che ammira i valori del cristianesimo (come Kant e Pascal) e che si avvicina al messaggio cristiano vivendolo dal punto di vista etico.  Per le posizioni su questa tematica Pera è considerato un esponente del movimento neoconservatore italiano e risulta essere attualmente il più autorevole esponente Teocon in Italia. Nel periodo di presidenza del Senato nasce un legame intellettuale tra Pera e il cardinale Joseph Ratzinger, il futuro pontefice Benedetto XVI: i due si trovano in sintonia sull'analisi dei problemi dell'Europa e manifestano comuni preoccupazioni per una civiltà occidentale minata al suo interno dal relativismo e dal multiculturalismo.[18]  Dopo il 2000 Pera ha dedicato diversi articoli e saggi al rapporto fra la cultura storica europea e il cattolicesimo. In generale Marcello Pera sostiene che il denominatore culturale comune dei diversi stati europei non deve ravvisarsi nel rinascimento o nell'illuminismo, ma nel Cristianesimo[19]. Pera in alcuni saggi e interviste ha indicato l'esigenza di ricercare l'identità culturale del continente europeo nel Vangelo e negli Atti degli Apostoli. In particolare Pera ha sostenuto che le Lettere di S.Paolo e i racconti evangelici esprimono i concetti di eguaglianza fra gli uomini e di solidarietà sociale, che sono oggi alla base delle Costituzioni delle nazioni moderne e della stessa Comunità Europea.  Nel 2004 Pera è autore con l'allora cardinale Joseph Ratzinger del libro “Senza radici”, sulla questione delle radici cristiane dell'Europa. Nel libro, che contiene le due relazioni di Pera e Ratzinger sull'argomento e uno scambio epistolare tra i due, denuncia il decadimento morale dell'Europa a suo dire impoverita dal rifiuto delle sue radici cristiane e minacciata dal terrorismo islamista. Nel libro Pera scrive: «Soffia sull'Europa un brutto vento. Si tratta dell'idea che basta aspettare e i guai spariranno da soli, o che si può essere accondiscendenti anche con chi ci minaccia e potremo cavarcela. È lo stesso soffio del vento di Monaco nel 1938». In un'intervista rilasciata alla Stampa dopo il no irlandese al trattato europeo, Pera identifica il Papa, sulla scia di De Maistre, come unico riferimento possibile per il Vecchio Continente.[20]  Nel saggio Perché dobbiamo dirci cristiani (2008) Pera condanna il relativismo e l'incertezza culturale della società contemporanea e sviluppa il tema della vera identità dell'Europa da ricercarsi nella forza etica e sociale del cristianesimo. Secondo Pera, la religione cattolica non può essere una convinzione privata o tradizionale: l'impegno del cattolico deve essere presente nella coerenza del suo comportamento etico. Secondo Pera, il cristiano si deve impegnare in tutte le sfere della vita civile e istituzionale, prestando la sua attenzione ai problemi di tutti i cittadini e alla solidarietà sociale. Sul piano politico e culturale, Marcello Pera si definisce un "conservatore liberale". Più precisamente “conservatore sui valori da mantenere e liberale sulle riforme da fare”. Secondo Pera “si tratta di una grande dottrina, una grande scuola, una grande tradizione politica. Si basa soprattutto su due pilastri: attenzione e difesa della nostra tradizione europea e occidentale, che è il riferimento da mantenere (da ciò il conservatorismo); e custodia della nostra autonomia individuale, che è la condizione su cui dobbiamo sempre vigilare (da ciò il nostro liberalismo)”.[21] Opere Induzione e metodo scientifico, Pisa, Editrice Tecnico Scientifica, 1978.

izzing/hazzing – per-essentiam/per-accidentem: literally, “by, as, or being an accident or non-essential feature.” A “per accidens” predication Grice calls a hazzing (not an izzing) and is one in which an accident is predicated of a substance. The terminology is medieval. Note that the accident and substance themselves, and not expressions standing for them, are the terms of the predication relation. An “ens per accidentem” is either an accident or the “accidental unity” of a substance and an accident. Descartes, e.g., insists that a person is not a “per accidentem” union of body and mind. H. P. Grice, “Izzing, hazzing: the per-essentiam/per-accidentem distinction.”

PENDENS -- DE-PENDENS -- dependens- independens distinction, the: independence results, proofs of non-deducibility. Any of the following equivalent conditions may be called independence: (1) A is not deducible from B; (2) its negation - A is consistent with B; (3) there is a model of B that is not a model of A; e.g., the question of the non-deducibility of the parallel axiom from the other Euclidean axioms is equivalent to that of the consistency of its negation with them, i.e. of non-Euclidean geometry. Independence results may be not absolute but relative, of the form: if B is consistent (or has a model), then B together with - A is (or does); e.g. models of non-Euclidean geometry are built within Euclidean geometry. In another sense, a set B is said to be independent if it is irredundant, i.e., each hypothesis in B is independent of the others; in yet another sense, A is said to be independent of B if it is undecidable by B, i.e., both independent of and consistent with B. The incompleteness theorems of Gödel are independence results, prototypes for many further proofs of undecidability by subsystems of classical mathematics, or by classical mathematics as a whole, as formalized in ZermeloFraenkel set theory with the axiom of choice (ZF ! AC or ZFC). Most famous is the undecidability of the continuum hypothesis, proved consistent relative to ZFC by Gödel, using his method of constructible sets, and independent relative to ZFC by Paul J. Cohen, using his method of forcing. Rather than build models from scratch by such methods, independence (consistency) for A can also be established by showing A implies (is implied by ) some A* already known independent (consistent). Many suitable A* (Jensen’s Diamond, Martin’s Axiom, etc.) are now available. Philosophically, formalism takes A’s undecidability by ZFC to show the question of A’s truth meaningless; Platonism takes it to establish the need for new axioms, such as those of large cardinals. (Considerations related to the incompleteness theorems show that there is no hope even of a relative consistency proof for these axioms, yet they imply, by way of determinacy axioms, many important consequences about real numbers that are independent of ZFC.) With non-classical logics, e.g. second-order logic, (1)–(3) above may not be equivalent, so several senses of independence become distinguishable. The question of independence of one axiom from others may be raised also for formalizations of logic itself, where many-valued logics provide models.

perceptum: vide Grice/Warnock, “Notes on visa.” -- myse-en-abyme, drodde effect Dahlenmacher, speculative – mirror in front of mirror -- , the traditional distinction is perceptum-conceptum: nihil est in intellectu quod prius non fuerit in sensu. this is Grice on sense-datum. Grice feels that the kettle is hot; Grice sees that the kettle is hot; Grice perceives that the kettle is hot. WoW:251 uses this example. It may be argued that the use of ‘see’ is there NOT factive. Cf. “I feel hot but it’s not hot.” Grice modifies the thing to read, “DIRECTLY PERCEIVING”: Grice only indirectly perceives that the kettle is hot’ if what he is doing is ‘seeing’ that the kettle is hot. When Grice sees that the kettle is hot, it is a ‘secondary’ usage of ‘see,’ because it means that Grice perceives that the kettle has some visual property that INDICATES the presence of hotness (Grice uses phi for the general formula). Cf. sensum. Lewis and Short have “sentĭo,” which they render, aptly, as “to sense,” ‘to discern by the senses; to feel, hear, see, etc.; to perceive, be sensible of (syn. percipio).” Note that Price is also cited by Grice in Personal identity. Grice: That pillar box seems red to me. The locus classicus in the philosophical literature for Grices implicaturum. Grice introduces a dout-or-denial condition for an utterance of a phenomenalist report (That pillar-box seems red to me). Grice attacks neo-Wittgensteinian approaches that regard the report as _false_. In a long excursus on implication, he compares the phenomenalist report with utterances like He has beautiful handwriting (He is hopeless at philosophy), a particularised conversational implicaturum; My wife is in the kitchen or the garden (I have non-truth-functional grounds to utter this), a generalised conversational implicaturum; She was poor but she was honest (a Great-War witty (her poverty and her honesty contrast), a conventional implicaturum; and Have you stopped beating your wife? an old Oxonian conundrum. You have been beating your wife, cf. Smith has not ceased from eating iron, a presupposition. More importantly, he considers different tests for each concoction! Those for the conversational implicaturum will become crucial: cancellability, calculability, non-detachability, and indeterminacy. In the proceedings he plays with something like the principle of conversational helpfulness, as having a basis on a view of conversation as rational co-operation, and as giving the rationale to the implicaturum. Past the excursus, and back to the issue of perception, he holds a conservative view as presented by Price at Oxford. One interesting reprint of Grices essay is in Daviss volume on Causal theories, since this is where it belongs! White’s response is usually ignored, but shouldnt. White is an interesting Australian philosopher at Oxford who is usually regarded as a practitioner of ordinary-language philosophy. However, in his response, White hardly touches the issue of the implicaturum with which Grice is primarily concerned. Grice found that a full reprint from the PAS in a compilation also containing the James Harvard would be too repetitive. Therefore, he omits the excursus on implication. However, the way Grice re-formulates what that excursus covers is very interesting. There is the conversational implicaturum, particularised (Smith has beautiful handwriting) and generalised (My wife is in the kitchen or in the garden). Then there is the præsuppositum, or presupposition (You havent stopped beating your wife). Finally, there is the conventional implicaturum (She was poor, but she was honest). Even at Oxford, Grices implicaturum goes, philosophers ‒ even Oxonian philosophers ‒ use imply for all those different animals! Warnock had attended Austins Sense and Sensibilia (not to be confused with Sense and Sensibility by Austen), which Grice found boring, but Warnock didnt because Austin reviews his "Berkeley." But Warnock, for obvious reasons, preferred philosophical investigations with Grice. Warnock reminisces that Grice once tells him, and not on a Saturday morning, either, How clever language is, for they find that ordinary language does not need the concept of a visum. Grice and Warnock spent lovely occasions exploring what Oxford has as the philosophy of perception. While Grice later came to see philosophy of perception as a bit or an offshoot of philosophical psychology, the philosophy of perception is concerned with that treasured bit of the Oxonian philosophers lexicon, the sense-datum, always in the singular! The cause involved is crucial. Grice plays with an evolutionary justification of the material thing as the denotatum of a perceptual judgement. If a material thing causes the sense-datum of a nut, that is because the squarrel (or squirrel) will not be nourished by the sense datum of the nut; only by the nut! There are many other items in the Grice Collection that address the topic of perception – notably with Warnock, and criticizing members of the Ryle group like Roxbee-Cox (on vision, cf. visa ‒ taste, and perception, in general – And we should not forget that Grice contributed a splendid essay on the distinction of the senses to Butlers Analytic philosophy, which in a way, redeemed a rather old-fashioned discipline by shifting it to the idiom of the day, the philosophy of perception: a retrospective, with Warnock, the philosophy of perception, : perception, the philosophy of perception, visum. Warnock was possibly the only philosopher at Oxford Grice felt congenial enough to engage in different explorations in the so-called philosophy of perception. Their joint adventures involved the disimplicaturum of a visum. Grice later approached sense data in more evolutionary terms: a material thing is to be vindicated transcendentally, in the sense that it is a material thing (and not a sense datum or collection thereof) that nourishes a creature like a human. Grice was particularly grateful to Warnock. By reprinting the full symposium on “Causal theory” of perception in his influential s. of Oxford Readings in Philosophy, Warnock had spread Grices lore of implicaturum all over! In some parts of the draft he uses more on visa, vision, vision, with Warnock, vision. Of the five senses, Grice and Warnock are particularly interested in seeing. As Grice will put it later, see is a factive. It presupposes the existence of the event reported after the that-clause; a visum, however, as an intermediary between the material thing and the perceiver does not seem necessary in ordinary discourse. Warnock will reconsider Grices views too (On what is seen, in Sibley). While Grice uses vision, he knows he is interested in Philosophers paradox concerning seeing, notably Witters on seeing as, vision, taste and the philosophy of perception, vision, seeing. As an Oxonian philosopher, Grice was of course more interested in seeing than in vision. He said that Austin would criticise even the use of things like sensation and volition, taste, The Grice Papers, keyword: taste, the objects of the five senses, the philosophy of perception, perception, the philosophy of perception; philosophy of perception, vision, taste, perception. Mainly with Warnock. Warnock repr. Grice’s “Causal theory” in his influential Reading in Philosophy, The philosophy of perception, perception, with Warnock, with Warner; perception. Warnock learns about perception much more from Grice than from Austin, taste, The philosophy of perception, the philosophy of perception, notes with Warnock on visum, : visum, Warnock, Grice, the philosophy of perception.  Grice kept the lecture notes to a view of publishing a retrospective. Warnock recalled Grice saying, how clever language is! Grice took the offer by Harvard University Press, and it was a good thing he repr. part of “Causal theory.” However, the relevant bits for his theory of conversation as rational co-operation lie in the excursus which he omitted. What is Grices implicaturum: that one should consider the topic rather than the method here, being sense datum, and causation, rather than conversational helpfulness. After all, That pillar box seems red to me, does not sound very helpful. But the topic of Causal theory is central for his view of conversation as rational co-operation. Why? P1 gets an impression of danger as caused by the danger out there. He communicates the danger to P1, causing in P2 some behaviour. Without causation, or causal links, the very point of offering a theory of conversation as rational co-operation seems minimized. On top, as a metaphysician, he was also concerned with cause simpliciter. He was especially proud that Price’s section on the casual theory of perception, from his Belief, had been repr. along with his essay in the influential volume by Davis on “Causal theories.” In “Actions and events,” Grice further explores cause now in connection with Greek aitia. As Grice notes, the original usage of this very Grecian item is the one we find in rebel without a cause, cause-to, rather than cause-because. The two-movement nature of causing is reproduced in the conversational exchange: a material thing causes a sense datum which causes an expression which gets communicated, thus causing a psychological state which will cause a behaviour. This causation is almost representational. A material thing or a situation cannot govern our actions and behaviours, but a re-præsentatum of it might. Govern our actions and behaviour is Grices correlate of what a team of North-Oxfordshire cricketers can do for North-Oxfordshire: what North Oxfordshire cannot do for herself, Namesly, engage in a game of cricket! In Retrospective epilogue he casts doubts on the point of his causal approach. It is a short paragraph that merits much exploration. Basically, Grice is saying his causalist approach is hardly an established thesis. He also proposes a similar serious objection to his view in Some remarks about the senses, the other essay in the philosophy of perception in Studies. As he notes, both engage with some fundamental questions in the philosophy of perception, which is hardly the same thing as saying that they provide an answer to each question! Grice: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind. Examples which occur to me are the following six. You cannot see a knife ‘as’ a knife, though you may see what is not a knife ‘as’ a knife (keyword: ‘seeing as’). When he said he ‘knew’ that the objects before him were human hands, Moore was guilty of misusing ‘know.’ For an occurrence to be properly said to have a ‘cause,’ it must be something abnormal or unusual (keyword: ‘cause’). For an action to be properly described as one for which the agent is ‘responsible,’ it must be the sort of action for which people are condemned (keyword: responsibility). What is actual is not also possible (keyword: actual). What is known by me to be the case is not also believed by me to be the case (keyword: ‘know’ – cf. Urmson on ‘scalar set’). And cf. with the extra examples he presents in “Prolegomena.” I have no doubt that there will be other candidates besides the six which I have mentioned. I must emphasize that I am not saying that all these examples are importantly similar to the thesis which I have been criticizing, only that, for all I know, they may be. To put the matter more generally, the position adopted by my objector seems to me to involve a type of manoeuvre which is characteristic of more than one contemporary mode of philosophizing. I am not condemning this kind of manoeuvre. I am merely suggesting that to embark on it without due caution is to risk collision with the facts. Before we rush ahead to exploit the linguistic nuances which we have detectcd, we should make sure that we are reasonably clear what sort of nuances they are. “Causal theory”, knowledge and belief, knowledge, belief, philosophical psychology. Grice: the doxastic implicaturum. I know only implicates I do not believe. The following is a mistake by a philosopher. What is known by me to be the case is not also believed by me to be the case. The topic had attracted the attention of some Oxonian philosophers such as Urmson in Parenthetical verbs. Urmson speaks of a scale: I know can be used parenthetically, as I believe can. For Grice, to utter I believe is obviously to make a weaker conversational move than you would if you utter I know. And in this case, an approach to informativeness in terms of entailment is in order, seeing that I know entails I believe. A is thus allowed to infer that the utterer is not in a position to make the stronger claim. The mechanism is explained via his principle of conversational helpfulness. Philosophers tend two over-use these two basic psychological states, attitudes, or stances. Grice is concerned with Gettier-type cases, and also the factivity of know versus the non-factivity of believe. Grice follows the lexicological innovations by Hintikka: the logic of belief is doxastic; the logic of knowledge is epistemic. The last thesis that Grice lists in Causal theory that he thinks rests on a big mistake he formulates as: What is known by me to be the case is NOT also believed by me to be the case. What are his attending remarks? Grice writes: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind. An example which occurs to me is the following: What is known by me to be the case is not also believed by me to be the case. I must emphasise that I am not saying that this example is importantly similar to the thesis which I have been criticising, only that, for all I know, it may be. To put the matter more generally, the position adopted by my objector seems to me to involve a type of manoeuvre which is characteristic of more than one contemporary mode of philosophizing. I am not condemning this kind of manoeuvre. I am merely suggesting that to embark on it without due caution is to risk collision with the facts. Before we rush ahead to exploit the linguistic nuances which we have detected, we should make sure that we are reasonably clear what SORT of nuances they are! The ætiological implicaturum. Grice. For an occurrence to be properly said to have a cause, it must be something abnormal or unusual. This is an example Grice lists in Causal theory but not in Prolegomena. But cf. ‘responsible’ – and Hart and Honoré on accusation -- accusare "call to account, make complaint against," from ad causa, from “ad,” with regard to, as in ‘ad-’) + causa, a cause; a lawsuit,’ v. cause. For an occurrence to be properly said to have a cause, it must be something abnormal or unusual. Similar commentary to his example on responsible/condemnable apply. The objector may stick with the fact that he is only concerned with proper utterances. Surely Grice wants to go to a pre-Humeian account of causation, possible Aristotelian, aetiologia. Where everything has a cause, except, for Aristotle, God! What are his attending remarks? Grice writes: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind.

Causal theory, cause, causality, causation, conference, colloquium, Stanford, cause, metaphysics, the abnormal/unusual implicaturum, ætiology, ætiological implicaturum. Grice: the ætiological implicaturum. Grices explorations on cause are very rich. He is concerned with some alleged misuse of cause in ordinary language. If as Hume suggests, to cause is to will, one would say that the decapitation of Charles I wills his death, which sounds harsh, if not ungrammatical, too. Grice later relates cause to the Greek aitia, as he should. He notes collocations like rebel without a cause. For the Greeks, or Grecians, as he called them, and the Griceians, it is a cause to which one should be involved in elucidating.  A ‘cause to’ connects with the idea of freedom. Grice was constantly aware of the threat of mechanism, and his idea was to provide philosophical room for the idea of finality, which is not mechanistically derivable. This leads him to discussion of overlap and priority of, say, a physical-cum-physiological versus a psychological theory explaining this or that piece of rational behaviour. Grice can be Wittgensteinian when citing Anscombes translation: No psychological concept without the behaviour the concept is brought to explain.  It is best to place his later treatment of cause with his earlier one in Causal theory. It is surprising Grice does not apply his example of a mistake by a philosopher to the causal bit of his causal theory. Grice states the philosophical mistake as follows: For an occurrence to be properly said to have a cause, it must be something abnormal or unusual. This is an example Grice lists in Causal theory but not in Prolegomena. For an occurrence to be properly said to have a cause, it must be something abnormal or unusual. A similar commentary to his example on responsible/condemnable applies: The objector may stick with the fact that he is only concerned with PROPER utterances. Surely Grice wants to embrace a pre-Humeian account of causation, possible Aristotelian. Keyword: Aitiologia, where everything has a cause, except, for Aristotle, God! What are his attending remarks? Grice writes: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would Grice thinks need to be examined in order to see whether or not they are sufficiently parallel to the thesis which Grice has been discussing to be amenable to treatment of the same general kind. One example which occurs to Grice is the following: For an occurrence to be properly said to have a cause, it must be something abnormal or unusual. Grice feels he must emphasise that he is not saying that this example is importantly similar to the thesis which I have been criticizing, only that, for all I know, it may be. To put the matter more generally, the position adopted by my objector seems to me to involve a type of manoeuvre which is characteristic of more than one contemporary mode of philosophizing. I am not condemning this kind of manoeuvre. I am merely suggesting that to embark on it without due caution is to risk collision with the facts. Before we rush ahead to exploit the linguistic nuances which we have detected, we should make sure that we are reasonably clear what sort of nuances they are! Re: responsibility/condemnation. Cf. Mabbott, Flew on punishment, Philosophy. And also Hart. At Corpus, Grice enjoys his tutor Hardies resourcefulness in the defence of what may be a difficult position, a characteristic illustrated by an incident which Hardie himself once told Grice about himself. Hardie had parked his car and gone to a cinema. Unfortunately, Hardie had parked his car on top of one of the strips on the street by means of which traffic-lights were, at the time, controlled by the passing traffic. As a result, the lights are jammed, and it requires four policemen to lift Hardies car off the strip. The police decides to prosecute. Grice indicated to Hardie that this hardly surprised him and asked him how he fared. Oh, Hardie says, I got off. Then Grice asks Hardie how on earth he managed that! Quite simply, Hardie answers. I just invoked Mills method of difference. The police charged me with causing an obstruction at 4 p.m. I told the police that, since my car was parked at 2 p.m., it could not have been my car which caused the obstruction at 4 p.m. This relates to an example in Causal theory that he Grice does not discuss in Prolegomena, but which may relate to Hart, and closer to Grice, to Mabbotts essay on Flew on punishment, in Philosophy. Grice states the philosophical mistake as follows: For an action to be properly described as one for which the agent is responsible, it must be thc sort of action for which people are condemned. As applied to Hardie. Is Hardie irresponsible? In any case, while condemnable, he was not! Grice writes: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind. An example which occurs to me is the following: For an action to be properly described as one for which the agent is responsible, it must be the sort of action for which people are condemned.

Before we rush ahead to exploit the linguistic nuances which we have detected, we should make sure that we are reasonably clear what sort of nuances they are. The modal example, what is actual is not also possible, should discussed under Indicative conditonals, Grice on Macbeth’s implicaturum: seeing a dagger as a dagger. Grice elaborates on this in Prolegomena, but the austerity of Causal theory is charming, since he does not give a quote or source. Obviously, Witters. Grice writes: Witters might say that one cannot see a knife as a knife, though one may see what is not a knife as a knife. The issue, Grice notes, with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind. An example which occurs to Grice is the following: You cannot see a knife as a knife, though you may see what is not a knife as a knife.

Is this a dagger which I see before me, the handle toward my hand? Come, let me clutch thee. I have thee not, and yet I see thee still. Art thou not, fatal vision, sensible to feeling as to sight? or art thou but A dagger of the mind, a false creation, Proceeding from the heat-oppressed brain? I see thee yet, in form as palpable as this which now I draw. Thou marshallst me the way that I was going; and such an instrument I was to use. Mine eyes are made the fools o the other senses, Or else worth all the rest; I see thee still, and on thy blade and dudgeon gouts of blood, which was not so before. Theres no such thing: It is the bloody business which informs Thus to mine eyes. Now oer the one halfworld Nature seems dead, and wicked dreams abuse The curtaind sleep; witchcraft celebrates Pale Hecates offerings, and witherd murder, Alarumd by his sentinel, the wolf, Whose howls his watch, thus with his stealthy pace. With Tarquins ravishing strides, towards his design Moves like a ghost. Thou sure and firm-set earth, Hear not my steps, which way they walk, for fear Thy very stones prate of my whereabout, And take the present horror from the time, Which now suits with it. Whiles I threat, he lives: Words to the heat of deeds too cold breath gives. I go, and it is done; the bell invites me. Hear it not, Duncan; for it is a knell that summons thee to heaven or to hell. The Moore example is used both in “Causal theory” and “Prolegomena.” But the use in “Causal Theory” is more austere: Philosophers mistake: Malcolm: When Moore said he knew that the objects before him were human hands, he was guilty of misusing the word know. Grice writes: The issue with which I have been mainly concerned may be thought rather a fine point, but it is certainly not an isolated one. There are several philosophical theses or dicta which would I think need to be examined in order to see whether or not they are sufficiently parallel to the thesis which I have been discussing to be amenable to treatment of the same general kind. An example which occurs to me is the following: When Moore said he knew that the objects before him were human hands, he was guilty of misusing the word know. I must emphasise that I am not saying that this example is importantly similar to the thesis which I have been criticizing, only that, for all I know, it may be.

I am not condemning this kind of manoeuvre. Grice is merely suggesting that to embark on it without due caution is to risk collision with the facts. Before we rush ahead to exploit the linguistic nuances which we have detected, we should make sure that we are reasonably clear what sort of nuances they are! So surely Grice is meaning: I know that the objects before me are human hands as uttered by Moore is possibly true. Grice was amused by the fact that while at Madison, Wisc., Moore gave the example: I know that behind those curtains there is a window. Actually he was wrong, as he soon realised when the educated Madisonians corrected him with a roar of unanimous laughter. You see, the lecture hall of the University of Wisconsin at Madison is a rather, shall we say, striking space. The architect designed the lecture hall with a parapet running around the wall just below the ceiling, cleverly rigged with indirect lighting to create the illusion that sun light is pouring in through windows from outside. So, Moore comes to give a lecture one sunny day. Attracted as he was to this eccentric architectural detail, Moore gives an illustration of certainty as attached to common sense. Pointing to the space below the ceiling, Moore utters. We know more things than we think we know. I know, for example, that the sunlight shining in from outside proves  At which point he was somewhat startled (in his reserved Irish-English sort of way) when his audience burst out laughing! Is that a proof of anything? Grice is especially concerned with I seem He needs a paradeigmatic sense-datum utterance, and intentionalist as he was, he finds it in I seem to see a red pillar box before me. He is relying on Paul. Grice would generalise a sense datum by φ I seem to perceive that the alpha is phi. He agrees that while cause may be too much, any sentence using because will do: At a circus: You seem to be seeing that an elephant is coming down the street because an elephant is coming down the street. Grice found the causalist theory of perception particularly attractive since its objection commits one same mistake twice: he mischaracterises the cancellable implicaturum of both seem and cause! While Grice is approaching the philosophical item in the philosophical lexicon, perceptio, he is at this stage more interested in vernacular that- clauses such as sensing that, or even more vernacular ones like seeming that, if not seeing that! This is of course philosophical (cf. aesthetikos vs. noetikos). L and S have “perceptĭo,” f. perceptio, as used by Cicero (Ac. 2, 7, 22) translating catalepsis, and which they render as “a taking, receiving; a gathering in, collecting;’ frugum fruetuumque reliquorum, Cic. Off. 2, 3, 12: fructuum;’ also as perception, comprehension, cf.: notio, cognition; animi perceptiones, notions, ideas; cognitio aut perceptio, aut si verbum e verbo volumus comprehensio, quam κατάληψιν illi vocant; in philosophy, direct apprehension of an object by the mind, Zeno Stoic.1.20, Luc. Par. 4, al.; τῶν μετεώρων;” ἀκριβὴς κ. Certainty; pl., perceptions, Stoic.2.30, Luc. Herm.81, etc.; introduced into Latin by Cicero, Plu. Cic. 40. As for “causa” Grice is even more sure he was exploring a time-honoured philosophical topic. The entry in L and S is “causa,’ perh. root “cav-“ of “caveo,” prop. that which is defended or protected; cf. “cura,” and that they render as, unhelpfully, as “cause,” “that by, on account of, or through which any thing takes place or is done;” “a cause, reason, motive, inducement;” also, in gen., an occasion, opportunity; oeffectis;  factis, syn. with ratio, principium, fons, origo, caput; excusatio, defensio; judicium, controversia, lis; partes, actio; condicio, negotium, commodum, al.); correlated to aition, or aitia, cause, δι᾽ ἣν αἰτίην ἐπολέμησαν,” cf. Pl. Ti. 68e, Phd. 97a sq.; on the four causes of Arist. v. Ph. 194b16, Metaph. 983a26: αἰ. τοῦ γενέσθαι or γεγονέναι Pl. Phd. 97a; τοῦ μεγίστου ἀγαθοῦ τῇ πόλει αἰτία ἡ κοινωνία Id. R. 464b: αἰτίᾳ for the sake of, κοινοῦ τινος ἀγαθοῦ.” Then there is “αἴτιον” (cf. ‘αἴτιος’) is used like “αἰτία” in the sense of cause, not in that of ‘accusation.’ Grice goes back to perception at a later stage, reminiscing on his joint endeavours with akin Warnock, Ps karulise elatically, potching and cotching obbles, Pirotese, Pirotese, creature construction, philosophical psychology. Grice was fascinated by Carnaps Ps which karulise elatically. Grice adds potching for something like perceiving and cotching for something like cognising. With his essay Some remarks about the senses, Grice introduces the question by which criterion we distinguish our five senses into the contemporary philosophy of perception. The literature concerning this question is not very numerous but the discussion is still alive and was lately inspired by the volume The Senses2. There are four acknowledged possible answers to the question how we distinguish the senses, all of them already stated by Grice. First, the senses are distinguished by the properties we perceive by them. Second, the senses are distinguished by the phenomenal qualities of the perception itself or as Grice puts it “by the special introspectible character of the experiences” Third, the senses are distinguished by the physical stimuli that are responsible for the relevant perceptions. Fourth, The senses are distinguished by the sense-organs that are (causally) involved in the production of the relevant perceptions. Most contributions discussing this issue reject the third and fourth answers in a very short argumentation. Nearly all philosophers writing on the topic vote either for the first or the second answer. Accordingly, most part of the debate regarding the initial question takes the form of a dispute between these two positions. Or” was a big thing in Oxford philosophy. The only known published work of Wood, our philosophy tutor at Christ Church, was an essay in Mind, the philosophers journal, entitled “Alternative Uses of “Or” ”, a work which was every bit as indeterminate as its title. Several years later he published another paper, this time for the Aristotelian Society, entitled On being forced to a conclusion. Cf. Grice and Wood on the demands of conversational reason. Wood, The force of linguistic rules. Wood, on the implicaturum of or in review in Mind of Connor, Logic. The five senses, as Urmson notes, are to see that the sun is shining, to hear that the car collided, to feel that her pulse is beating, to smell that something has been smoking and to taste that. An interesting piece in that it was commissioned by Butler, who knew Grice from his Oxford days. Grice cites Wood and Albritton. Grice is concerned with a special topic in the philosophy of perception, notably the identification of the traditional five senses: vision, audition, taste, smell, and tact. He introduces what is regarded in the philosophical literature as the first thought-experiment, in terms of the senses that Martians may have. They have two pairs of eyes: are we going to allow that they see with both pairs? Grice introduces a sub-division of seeing: a Martian x-s an object with his upper pair of eyes, but he y-s an object with the lower pair of eyes. In his exploration, he takes a realist stance, which respects the ordinary discursive ways to approach issues of perception. A second interesting point is that in allowing this to be repr. in Butlers Analytic philosophy, Grice is demonstrating that analytic philosophers should NOT be obsessed with ordinary language. Butlers compilation, a rather dry one, is meant as a response to the more linguistic oriented ones by Flew (Grices first tutee at St. Johns, as it happens), also published by Blackwell, and containing pieces by Austin, and company. One philosopher who took Grice very seriously on this was Coady, in his The senses of the Martians. Grice provides a serious objection to his own essay in Retrospective epilogue We see with our eyes. I.e. eye is teleologically defined. He notes that his way of distinguishing the senses is hardly an established thesis. Grice actually advances this topic in his earlier Causal theory. Grice sees nothing absurd in the idea that a non-specialist concept should contain, so to speak, a blank space to be filled in by the specialist; that this is so, e.g., in the case of the concept of seeing is perhaps indicated by the consideration that if we were in doubt about the correctness of speaking of a certain creature with peculiar sense-organs as seeing objects, we might well wish to hear from a specialist a comparative account of the human eye and the relevant sense-organs of the creature in question. He returns to the point in Retrospective epilogue with a bit of doxastic humility, We see with our eyes is analytic  ‒ but philosophers should take that more seriously.  Grice tested the playmates of his children, aged 7 and 9, with Nothing can be green and red all over. Instead, Morley Bunker preferred philosophy undergrads. Aint that boring? To give examples: Summer follows Spring was judged analytic by Morley-Bunkers informants, as cited by Sampson, in Making sense (Clarendon) by highly significant majorities in each group of Subjectss, while We see with our eyes was given near-even split votes by each group. Over all, the philosophers were somewhat more consistent with each other than the non-philosophers. But that global finding conceals results for individual sentences that sometimes manifested the opposed tendency. Thus, Thunderstorms are electrical disturbances in the atmosphere is judged analytic by a highly significant majority of the non-philosophers, while a non-significant majority of the philosophers deemed it non-analytic or synthetic. In this case, it seems, philosophical training, surely not brain-washing, induces the realisation that well-established results of contemporary science are not necessary truths. In other cases, conversely, cliches of current philosophical education impose their own mental blinkers on those who undergo it: Nothing can be completely red and green all over is judged analytic by a significant majority of philosophers but only by a non-significant majority of non-philosophers. All in all, the results argue strongly against the notion that our inability to decide consistently whether or not some statement is a necessary truth derives from lack of skill in articulating our underlying knowledge of the rules of our language. Rather, the inability comes from the fact that the question as posed is unreal. We choose to treat a given statement as open to question or as unchallengeable in the light of the overall structure of beliefs which we have individually evolved in order to make sense of our individual experience. Even the cases which seem clearly analytic or synthetic are cases which individuals judge alike because the relevant experiences are shared by the whole community, but even for such cases one can invent hypothetical or suppositional future experiences which, if they should be realised, would cause us to revise our judgements. This is not intended to call into question the special status of the truths of logic, such as either Either it is raining or it is not. He is of course inclined to accept the traditional view according to which logical particles such as not and or are distinct from the bulk of the vocabulary in that the former really are governed by clear-cut inference rules. Grice does expand on the point. Refs.: Under sense-datum, there are groups of essays. The obvious ones are the two essays on the philosophy of perception in WOW. A second group relates to his research with G. J. Warnock, where the keywords are ‘vision,’ ‘taste,’ and ‘perception,’ in general. There is a more recent group with this research with R. Warner. ‘Visum’ and ‘visa’ are good keywords, and cf. the use of ‘senses’ in “Some remarks about the senses,” in BANC.Philo: Grice’s favourite philosopher, after Ariskant. The [Greek: protos logos anapodeiktos] of the Stoic logic ran thus [Greek: ei hemera esti, phos estin ... alla men hemera estin phos ara estin] (Sext. _P.H._ II. 157, and other passages qu. Zeller 114). This bears a semblance of inference and isnot so utterly tautological as Cic.'s translation, which merges [Greek: phos] and [Greek: hemera] into one word, or that of Zeller (114, note). Si dies est lucet: a better trans of Greek: ei phos estin, hemera estin] than was given in 96, where see n. _Aliter Philoni_: not Philo of Larissa, but a noted dialectician, pupil of Diodorus the Megarian, mentioned also in 75. The dispute between Diodorus and Philo is mentioned in Sext. _A.M._ VIII. 115--117 with the same purpose as here, see also Zeller 39. Conexi = Gr. “synemmenon,” cf. Zeller 109. This was the proper term for the hypothetical judgment. _Superius_: the Greek: synemmenon consists of two parts, the hypothetical part and the affirmative--called in Greek [Greek: hegoumenon] and [Greek: legon]; if one is admitted the other follows of course.Philo's criterion for the truth of “if p, q” is truth-functional. Philo’s truth-functional criterion is generally accepted as a minimal condition.Philo maintains that “If Smith is in London, he, viz. Smith, is attending the meeting there, viz. in London” is true (i) when the antecedens (“Smith is in London”) is true and the consequens (“Smith is in London at a meeting”) is true (row 1) and (ii) when the antecedent is false (rows 3 and 4); false only when the antecedens (“Smith is in London”) is true and the consequens (“Smith is in London, at a meeting”) is false. (Sext. Emp., A. M., 2.113-114). Philo’s “if p, q” is what Whitehead and Russell call, misleadingly, ‘material’ implication, for it’s neither an implication, nor materia.In “The Influence of Grice on Philo,” Shropshire puts forward the thesis that Philo was aware of Griceian ideas on relative identity, particularly time-relative identity. Accordingly, Philo uses subscript for temporal indexes. Once famous discussion took place one long winter night.“If it is day, it is night.”“False!” Diodorus screamed.“True,” his tutee Philo courteously responded. “But true at night only.”Philo's suggestion is remarkable – although not that remarkable if we assume he read the now lost Griceian tract.Philo’s “if,” like Grice’s “if,” – on a bad day -- deviates noticeably from what Austin (and indeed, Austen) used to refer to as ‘ordinary’ language.As Philo rotundly says: “The Griceian ‘if’ requires abstraction on the basis of a concept of truth-functionality – and not all tutees will succeed in GETTING that.” The hint was on Strawson.Philo's ‘if’ has been criticised on two counts. First, as with Whitehead’s and Russell’s equally odd ‘if,’ – which they symbolise with an ‘inverted’ C, to irritate Johnson, -- “They think ‘c’ stands for either ‘consequentia’ or ‘contentum’ -- in the case of material implication, for the truth of the conditional no connection (or better, Kant’s relation) of content between antecedent and consequent is required. Uttered or emitted during the day, e. g.  ‘If virtue benefits, it is day’ is Philonianly true. This introduces a variant of the so-called ‘paradoxes’ of material implication (Relevance LogicConditionals 2.3; also, English Oxonian philosopher Lemmon 59-60, 82). This or that ancient philosopher was aware of what he thought was a ‘problem’ for Philo’s ‘if.’ Vide: SE, ibid. 113-117). On a second count, due to the time-dependency or relativity of the ‘Hellenistic’ ‘proposition,’ Philo's truth-functional criterion implies that ‘if p, q’ changes its truth-value over time, which amuses Grice, but makes Strawson sick. In Philo’s infamous metalinguistic disquotational version that Grice finds genial:‘If it is day, it is night’ is true if it is night, but false if it is day. This is counter-intuitive in Strawson’s “London,” urban, idiolect (Grice is from the Heart of England) as regards an utterance in ‘ordinary-language’ involving ‘if.’“We are not THAT otiose at busy London!On a third count, as the concept of “if” (‘doubt’ in Frisian) also meant to provide for consequentia between from a premise to a conclusio, this leads to the “rather” problematic result – Aquinas, S. T. ix. 34) that an ‘argumentum,’ as Boethius calls it, can in principle change from being valid to being invalid and vice versa, which did not please the Saint Thomas (Aquinas), “or God, matter of fact.”From Sextus: A. M., 2.113ffA non-simple proposition is such composed of a duplicated proposition or of this or that differing proposition. A complex proposition is controlled by this or that conjunction. 109. Of these let us take the hypo-thetical proposition, so-called. This, then, is composed of a duplicated proposition or of differing propositions, by means of the conjunction “if” (Gr. ‘ei,’ L. ‘si’, German ‘ob’). Thus, e. g. from a duplicated proposition and the conjunction “if” (Gr. ‘ei,’ L. ‘si,’ G. ‘ob’) there is composed such a hypothetical proposition as this. “If it is day, it is day’ (110) and from differing propositions, and by means of the conjunction “if” , one in this form, “If it is day, it is light.” “Si dies est, lucet.” And of the two propositions contained in the hypo-thetical proposition, or subordinating clause that which is placed immediately AFTER the conjunction or subordinating particle “if”  is called “ante-cedent,” or “first;” and ‘if’ being ‘noncommutative,’ and the other one “consequent” or “second,” EVEN if the whole proposition is reversed IN ORDER OF EXPRESSION – this is a conceptual issue, not a grammatical one! -- as thus — “It is light, if it is day.” For in this, too, the proposition, “It is light,” (lucet) is called consequent although it is UTTERED first, and ‘It is day’ antecedent, although it is UTTERED second, owing to the fact that it is placed after the conjunction or subordinating particle “if.” 111. Such then is the construction of the hypothetical proposition, and a proposition of this kind seems to “promise” (or suggest, or implicate) that the ‘consequent’ (or super-ordinated or main proposition) logically follows the ‘antecedens,’ or sub-ordinated proposition. If the antecedens is true, the consequens is true. Hence, if this sort of “promise,” suggestio, implicaturum, or what have you, is fulfilled and the consequens follows the antecedent, the hypothetical proposition is true. If the promise is not fulfilled, it is false (This is something Strawson grants as a complication in the sentence exactly after the passage that Grice extracts – Let’s revise Strawson’s exact wording. Strawson writes:“There is much more to be noted about ‘if.’ In particular, about whether the antecedens has to be a ‘GOOD’ antecedens, i. e. a ‘good’ ground – not inadmissible evidence, say -- or good reason for accepting the consequens, and whether THIS is a necessary condition for the whole ‘if’ utterance to be TRUE.’ Surely not for Philo. Philo’s criterion is that an ‘if’ utterance is true iff it is NOT the case that the antecedens is true and it is not the case that the consequens is true. 112. Accordingly, let us begin at once with this problem, and consider whether any hypothetical proposition can be found which is true and which fulfills the promise or suggestio or implicaturum described. Now all philosophers agree that a hypothetical proposition is true when the consequent follows the antecedent. As to when the consequens follows from the antecedens philosophers such as Grice and his tutee Strawson disagree with one another and propound conflicting criteria. 113. Philo and Grice declares that the ‘if’ utterance is true whenever it is not the case that the antecedens (“Smith is in London”) is true and it is not the case that the consequens (“Smith is in London attending a meeting”) is true. So that, according to Grice and Philo (vide, “The influence of Grice on Philo”), the hypothetical is true in three ways or rows (row 1, row 3, and row 4) and false in one way or row (second row, antecedens T and consequence F). For the first row, whenever the ‘if’ utterance begins with truth and ends in truth it is true. E. g. “If it is day, it is light.” “Si dies est, lux est.”For row 4: the ‘if’ utterance is also true whenever the antecedens is false and the consequens is false. E. g. “If the earth flies, the earth has wings.” ει πέταται ή γή, πτέρυγας έχει ή γή (“ei petatai he ge, pteguras ekhei he ge”) (Si terra volat, habet alas.”)114. Likewise also that which begins with what is false and ends with what is true is true, as thus — If the earth flies, the earth exists. “Si terra volat, est terra”. dialecticis, in quibus ſubtilitatem nimiam laudando, niſi fallimur, tradu xit Callimachus. 2 Cujus I. ſpecimen nobis fervavit se XTVS EMPI .

MOSHEMIV S . n . irAnd it is false only in this one way, when it begins with truth and ends in what is false, as in a proposition of this kind. “If it is day, it is night.” “Si dies est, nox est”.  (Cf. Cole Porter, “Night and day, day and night!”.For if it IS day, the clause ‘It is day’ is true, and this is the antecedent, but the clause ‘It is night,’ which is the consequens, is false. But when uttered at night, it is true. 115. — But Diodorus asserts that the hypothetical proposition is true which neither admitted nor admits of beginning with truth and ending in falsehood. And this is in conflict with the statement of Philo. For a hypothetical of this kind — If it is day, I am conversing, when at the present moment it is day and I am conversing, is true according to Philo since it begins with the true clause It is day and ends with the true I am conversing; but according to Diodorus it is false, for it admits of beginning with a clause that is, at one time, true and ending in the false clause I am conversing, when I have ceased speaking; also it admitted of beginning with truth and ending with the falsehood I am conversing, 116. for before I began to converse it began with the truth It is day and ended in the falsehood I am conversing. Again, a proposition in this form — If it is night, I am conversing, when it is day and I am silent, is likewise true according to Philo, for it begins with what is false and ends in what is false; but according to Diodorus it is false, for it admits of beginning with truth and ending in falsehood, after night has come on, and when I, again, am not conversing but keeping silence. 117. Moreover, the proposition If it is night, it is day, when it is day, is true according to Philo for the reason that it begins with the false It is night and ends in the true It is day; but according to Diodorus it is false for the reason that it admits of beginning, when night comes on, with the truth It is night and ending in the falsehood It is day.Philo is sometimes called ‘Philo of Megara,’ where ‘of’ is used alla Nancy Mitford, of Chatworth. Although no essay by Philo is preserved (if he wrote it), there are a number of reports of his doctrine, not all positive!Some think Philo made a groundbreaking contribution to the development of semantics (influencing Peirce, but then Peirce was influenced by the World in its totality), in particular to the philosophy of “as if” (als ob), or “if.”A conditional (sunêmmenon), as Philo calls it, is a non-simple, i. e. molecular, non atomic, proposition composed of two propositions, a main, or better super-ordinated proposition, or consequens, and a sub-ordinated proposition, the antecedens, and the subordinator ‘if’. Philo invented (possibly influenced by Frege) what he (Frege, not Philo) calls truth-functionality.Philo puts forward a criterion of truth as he called what Witters will have as a ‘truth table’ for ‘if’ (or ‘ob,’ cognate with Frisian gif, doubt).A conditional is is true in three truth-value combinations, and false  when and only when its antecedent is true and its consequent is false.The Philonian ‘if’ Whitehead and Russell re-labelled ‘material’ implication – irritating Johnson who published a letter in The Times, “… and dealing with the paradox of implication.”For Philo, like Grice, a proposition is a function of time that can have different truth-values at different times—it may change its truth-value over time. In Philo’s disquotational formula for ‘if’:“If it is day, ‘if it is day, it is night’ is false; if it is night, ‘if it is day, it is night’ is true.”(Tarski translated to Polish, in which language Grice read it).Philo’s ramblings on ‘if’ lead to foreshadows of Whitehead’s and Russell’s ‘paradox of implication’ that infuriated Johnson – In Russell’s response in the Times, he makes it plain: “Johnson shouldn’t be using ‘paradox’ in the singular. Yours, etc. Baron Russell, Belgravia.”Sextus Empiricus [S. E.] M. 8.109–117, gives a precis of Johnson’s paradox of implication, without crediting Johnson. Philo and Diodorus each considered the four modalities possibility, impossibility, necessity and non-necessity. These were conceived of as modal properties or modal values of propositions, not as modal operators. Philo defined them as follows: ‘Possible is that which is capable of being true by the proposition’s own nature … necessary is that which is true, and which, as far as it is in itself, is not capable of being false. Non-necessary is that which as far as it is in itself, is capable of being false, and impossible is that which by its own nature is not capable of being true.’ Boethius fell in love with Philo, and he SAID it! (In Arist. De Int., sec. ed., 234–235 Meiser).Cf. (Epict. Diss. II.19). Aristotle’s De Interpretatione 9  (Aulus Gellius 11.12.2–3). Grice: “Vision was always held by philosophers to be the superior sense.” Grice: “Perception is, strictly, the extraction and use of information about one’s environment exteroception and one’s own body interoception. “ he various external senses  sight, hearing, touch, smell, and taste  though they overlap to some extent, are distinguished by the kind of information e.g., about light, sound, temperature, pressure they deliver. Proprioception, perception of the self, concerns stimuli arising within, and carrying information about, one’s own body  e.g., acceleration, position, and orientation of the limbs. There are distinguishable stages in the extraction and use of sensory information, one an earlier stage corresponding to our perception of objects and events, the other, a later stage, to the perception of facts about these objects. We see, e.g., both the cat on the sofa an object and that the cat is on the sofa a fact. Seeing an object or event  a cat on the sofa, a person on the street, or a vehicle’s movement  does not require that the object event be identified or recognized in any particular way perhaps, though this is controversial, in any way whatsoever. One can, e.g., see a cat on the sofa and mistake it for a rumpled sweater. Airplane lights are often misidentified as stars, and one can see the movement of an object either as the movement of oneself or under some viewing conditions as expansion or contraction. Seeing objects and events is, in this sense, non-epistemic: one can see O without knowing or believing that it is O that one is seeing. Seeing facts, on the other hand, is epistemic; one cannot see that there is a cat on the sofa without, thereby, coming to know that there is a cat on the sofa. Seeing a fact is coming to know the fact in some visual way. One can see objects  the fly in one’s soup, e.g.,  without realizing that there is a fly in one’s soup thinking, perhaps, it is a bean or a crouton; but to see a fact, the fact that there is a fly in one’s soup is, necessarily, to know it is a fly. This distinction applies to the other sense modalities as well. One can hear the telephone ringing without realizing that it is the telephone perhaps it’s the TV or the doorbell, but to hear a fact, that it is the telephone that is ringing, is, of necessity, to know that it is the telephone that is ringing. The other ways we have of describing what we perceive are primarily variations on these two fundamental themes. In seeing where he went, when he left, who went with him, and how he was dressed, e.g., we are describing the perception of some fact of a certain sort without revealing exactly which fact it is. If Martha saw where he went, then Martha saw hence, came to know some fact having to do with where he went, some fact of the form ‘he went there’. In speaking of states and conditions the condition of his room, her injury, and properties the color of his tie, the height of the building, we sometimes, as in the case of objects, mean to be describing a non-epistemic perceptual act, one that carries no implications for what if anything is known. In other cases, as with facts, we mean to be describing the acquisition of some piece of knowledge. One can see or hear a word without recognizing it as a word it might be in a foreign language, but can one see a misprint and not know it is a misprint? It obviously depends on what one uses ‘misprint’ to refer to: an object a word that is misprinted or a fact the fact that it is misprinted. In examining and evaluating theories whether philosophical or psychological of perception it is essential to distinguish fact perception from object perception. For a theory might be a plausible theory about the perception of objects e.g., psychological theories of “early vision” but not at all plausible about our perception of facts. Fact perception, involving, as it does, knowledge and, hence, belief brings into play the entire cognitive system memory, concepts, etc. in a way the former does not. Perceptual relativity  e.g., the idea that what we perceive is relative to our language, our conceptual scheme, or the scientific theories we have available to “interpret” phenomena  is quite implausible as a theory about our perception of objects. A person lacking a word for, say, kumquats, lacking this concept, lacking a scientific way of classifying these objects are they a fruit? a vegetable? an animal?, can still see, touch, smell, and taste kumquats. Perception of objects does not depend on, and is therefore not relative to, the observer’s linguistic, conceptual, cognitive, and scientific assets or shortcomings. Fact perception, however, is another matter. Clearly one cannot see that there are kumquats in the basket as opposed to seeing the objects, the kumquats, in the basket if one has no idea of, no concept of, what a kumquat is. Seeing facts is much more sensitive and, hence, relative to the conceptual resources, the background knowledge and scientific theories, of the observer, and this difference must be kept in mind in evaluating claims about perceptual relativity. Though it does not make objects invisible, ignorance does tend to make facts perceptually inaccessible. There are characteristic experiences associated with the different senses. Tasting a kumquat is not at all like seeing a kumquat although the same object is perceived indeed, the same fact  that it is a kumquat  may be perceived. The difference, of course, is in the subjective experience one has in perceiving the kumquat. A causal theory of perception of objects holds that the perceptual object, what it is we see, taste, smell, or whatever, is that object that causes us to have this subjective experience. Perceiving an object is that object’s causing in the right way one to have an experience of the appropriate sort. I see a bean in my soup if it is, in fact whether I know it or not is irrelevant, a bean in my soup that is causing me to have this visual experience. I taste a bean if, in point of fact, it is a bean that is causing me to have the kind of taste experience I am now having. If it is unknown to me a bug, not a bean, that is causing these experiences, then I am unwittingly seeing and tasting a bug  perhaps a bug that looks and tastes like a bean. What object we see taste, smell, etc. is determined by the causal facts in question. What we know and believe, how we interpret the experience, is irrelevant, although it will, of course, determine what we say we see and taste. The same is to be said, with appropriate changes, for our perception of facts the most significant change being the replacement of belief for experience. I see that there is a bug in my soup if the fact that there is a bug in my soup causes me to perception perception 655    655 believe that there is a bug in my soup. I can taste that there is a bug in my soup when this fact causes me to have this belief via some taste sensation. A causal theory of perception is more than the claim that the physical objects we perceive cause us to have experiences and beliefs. This much is fairly obvious. It is the claim that this causal relation is constitutive of perception, that necessarily, if S sees O, then O causes a certain sort of experience in S. It is, according to this theory, impossible, on conceptual grounds, to perceive something with which one has no causal contact. If, e.g., future events do not cause present events, if there is no backward causation, then we cannot perceive future events and objects. Whether or not future facts can be perceived or known depends on how liberally the causal condition on knowledge is interpreted. Though conceding that there is a world of mind-independent objects trees, stars, people that cause us to have experiences, some philosophers  traditionally called representative realists  argue that we nonetheless do not directly perceive these external objects. What we directly perceive are the effects these objects have on us  an internal image, idea, or impression, a more or less depending on conditions of observation accurate representation of the external reality that helps produce it. This subjective, directly apprehended object has been called by various names: a sensation, percept, sensedatum, sensum, and sometimes, to emphasize its representational aspect, Vorstellung G., ‘representation’. Just as the images appearing on a television screen represent their remote causes the events occurring at some distant concert hall or playing field, the images visual, auditory, etc. that occur in the mind, the sensedata of which we are directly aware in normal perception, represent or sometimes, when things are not working right, misrepresent their external physical causes. The representative realist typically invokes arguments from illusion, facts about hallucination, and temporal considerations to support his view. Hallucinations are supposed to illustrate the way we can have the same kind of experience we have when as we commonly say we see a real bug without there being a real bug in our soup or anywhere else causing us to have the experience. When we hallucinate, the bug we “see” is, in fact, a figment of our own imagination, an image i.e., sense-datum in the mind that, because it shares some of the properties of a real bug shape, color, etc., we might mistake for a real bug. Since the subjective experiences can be indistinguishable from that which we have when as we commonly say we really see a bug, it is reasonable to infer the representative realist argues that in normal perception, when we take ourselves to be seeing a real bug, we are also directly aware of a buglike image in the mind. A hallucination differs from a normal perception, not in what we are aware of in both cases it is a sense-datum but in the cause of these experiences. In normal perception it is an actual bug; in hallucination it is, say, drugs in the bloodstream. In both cases, though, we are caused to have the same thing: an awareness of a buglike sense-datum, an object that, in normal perception, we naively take to be a real bug thus saying, and encouraging our children to say, that we see a bug. The argument from illusion points to the fact that our experience of an object changes even when the object that we perceive or say we perceive remains unchanged. Though the physical object the bug or whatever remains the same color, size, and shape, what we experience according to this argument changes color, shape, and size as we change the lighting, our viewing angle, and distance. Hence, it is concluded, what we experience cannot really be the physical object itself. Since it varies with changes in both object and viewing conditions, what we experience must be a causal result, an effect, of both the object we commonly say we see the bug and the conditions in which we view it. This internal effect, it is concluded, is a sense-datum. Representative realists have also appealed to the fact that perceiving a physical object is a causal process that takes time. This temporal lag is most dramatic in the case of distant objects e.g., stars, but it exists for every physical object it takes time for a neural signal to be transmitted from receptor surfaces to the brain. Consequently, at the moment a short time after light leaves the object’s surface we see a physical object, the object could no longer exist. It could have ceased to exist during the time light was being transmitted to the eye or during the time it takes the eye to communicate with the brain. Yet, even if the object ceases to exist before we become aware of anything before a visual experience occurs, we are, or so it seems, aware of something when the causal process reaches its climax in the brain. This something of which we are aware, since it cannot be the physical object it no longer exists, must be a sense-datum. The representationalist concludes in this “time-lag argument,” therefore, that even when the physperception perception 656    656 ical object does not cease to exist this, of course, is the normal situation, we are directly aware, not of it, but of its slightly later-occurring representation. Representative realists differ among themselves about the question of how much if at all the sense-data of which we are aware resemble the external objects of which we are not aware. Some take the external cause to have some of the properties the so-called primary properties of the datum e.g., extension and not others the so-called secondary properties  e.g., color. Direct or naive realism shares with representative realism a commitment to a world of independently existing objects. Both theories are forms of perceptual realism. It differs, however, in its view of how we are related to these objects in ordinary perception. Direct realists deny that we are aware of mental intermediaries sensedata when, as we ordinarily say, we see a tree or hear the telephone ring. Though direct realists differ in their degree of naïveté about how and in what respect perception is supposed to be direct, they need not be so naive as sometimes depicted as to deny the scientific facts about the causal processes underlying perception. Direct realists can easily admit, e.g., that physical objects cause us to have experiences of a particular kind, and that these experiences are private, subjective, or mental. They can even admit that it is this causal relationship between object and experience that constitutes our seeing and hearing physical objects. They need not, in other words, deny a causal theory of perception. What they must deny, if they are to remain direct realists, however, is an analysis of the subjective experience that objects cause us to have into an awareness of some object. For to understand this experience as an awareness of some object is, given the wholly subjective mental character of the experience itself, to interpose a mental entity what the experience is an awareness of between the perceiver and the physical object that causes him to have this experience, the physical object that is supposed to be directly perceived. Direct realists, therefore, avoid analyzing a perceptual experience into an act sensing, being aware of, being acquainted with and an object the sensum, sense-datum, sensation, mental representation. The experience we are caused to have when we perceive a physical object or event is, instead, to be understood in some other way. The adverbial theory is one such possibility. As the name suggests, this theory takes its cue from the way nouns and adjectives can sometimes be converted into adverbs without loss of descriptive content. So, for instance, it comes to pretty much the same thing whether we describe a conversation as animated adjective or say that we conversed animatedly an adverb. So, also, according to an adverbialist, when, as we commonly say, we see a red ball, the red ball causes in us a moment later an experience, yes, but not as the representative realist says an awareness mental act of a sense-datum mental object that is red and circular adjectives. The experience is better understood as one in which there is no object at all, as sensing redly and circularly adverbs. The adverbial theorist insists that one can experience circularly and redly without there being, in the mind or anywhere else, red circles this, in fact, is what the adverbialist thinks occurs in dreams and hallucinations of red circles. To experience redly is not to have a red experience; nor is it to experience redness in the mind. It is, says the adverbialist, a way or a manner of perceiving ordinary objects especially red ones seen in normal light. Just as dancing gracefully is not a thing we dance, so perceiving redly is not a thing  and certainly not a red thing in the mind  that we experience. The adverbial theory is only one option the direct realist has of acknowledging the causal basis of perception while, at the same time, maintaining the directness of our perceptual relation with independently existing objects. What is important is not that the experience be construed adverbially, but that it not be interpreted, as representative realists interpret it, as awareness of some internal object. For a direct realist, the appearances, though they are subjective mind-dependent are not objects that interpose themselves between the conscious mind and the external world. As classically understood, both naive and representative realism are theories about object perception. They differ about whether it is the external object or an internal object an idea in the mind that we most directly apprehend in ordinary sense perception. But they need not although they usually do differ in their analysis of our knowledge of the world around us, in their account of fact perception. A direct realist about object perception may, e.g., be an indirect realist about the facts that we know about these objects. To see, not only a red ball in front of one, but that there is a red ball in front of one, it may be necessary, even on a direct theory of object perception, to infer or in some way derive this fact from facts that are known more directly perception perception about one’s experiences of the ball. Since, e.g., a direct theorist may be a causal theorist, may think that seeing a red ball is in part constituted by the having of certain sorts of experience, she may insist that knowledge of the cause of these experiences must be derived from knowledge of the experience itself. If one is an adverbialist, e.g., one might insist that knowledge of physical objects is derived from knowledge of how redly? bluely? circularly? squarely? one experiences these objects. By the same token, a representative realist could adopt a direct theory of fact perception. Though the objects we directly see are mental, the facts we come to know by experiencing these subjective entities are facts about ordinary physical objects. We do not infer at least at no conscious level that there is a bug in our soup from facts known more directly about our own conscious experiences from facts about the sensations the bug causes in us. Rather, our sensations cause us, directly, to have beliefs about our soup. There is no intermediate belief; hence, there is no intermediate knowledge; hence, no intermediate fact perception. Fact perception is, in this sense, direct. Or so a representative realist can maintain even though committed to the indirect perception of the objects bug and soup involved in this fact. This merely illustrates, once again, the necessity of distinguishing object perception from fact perception. Refs.: H. P. Grice and A. R. White, “The causal theory of perception,” a symposium for the Aristotelian Socieety, in G. J. Warnock, “The philosophy of perception,” Oxford readings in philosophy.

Percival: English physician and author of Medical Ethics. He was central in bringing the Western traditions of medical ethics from prayers and oaths e.g., the Hippocratic oath toward more detailed, modern codes of proper professional conduct. His writing on the normative aspects of medical practice was part ethics, part prudential advice, part professional etiquette, and part jurisprudence. Medical Ethics treated standards for the professional conduct of physicians relative to surgeons and apothecaries pharmacists and general practitioners, as well as hospitals, private practice, and the law. The issues Percival addressed include privacy, truth telling, rules for professional consultation, human experimentation, public and private trust, compassion, sanity, suicide, abortion, capital punishment, and environmental nuisances. Percival had his greatest influence in England and America. At its founding in 1847, the  Medical Association used Medical Ethics to guide its own first code of medical ethics.

perdurance, endurance, continuance --  in one common philosophical use, the property of being temporally continuous and having temporal parts. There are at least two conflicting theories about temporally continuous substances. According to the first, temporally continuous substances have temporal parts they perdure, while according to the second, they do not. In one ordinary philosophical use, endurance is the property of being temporally continuous and not having temporal parts. There are modal versions of the aforementioned two theories: for example, one version of the first theory is that necessarily, temporally continuous substances have temporal parts, while another version implies that possibly, they do not. Some versions of the first theory hold that a temporally continuous substance is composed of instantaneous temporal parts or “object-stages,” while on other versions these object-stages are not parts but boundaries.  

perfect competition: perfect co-operation: the state of an ideal market under the following conditions: a every consumer in the market is a perfectly rational maximizer of utility; every producer is a perfect maximizer of profit; there is a very large ideally infinite number of producers of the good in question, which ensures that no producer can set the price for its output otherwise, an imperfect competitive state of oligopoly or monopoly obtains; and every producer provides a product perfectly indistinguishable from that of other producers if consumers could distinguish products to the point that there was no longer a very large number of producers for each distinguishable good, competition would again be imperfect. Under these conditions, the market price is equal to the marginal cost of producing the last unit. This in turn determines the market supply of the good, since each producer will gain by increasing production when price exceeds marginal cost and will generally cut losses by decreasing production when marginal cost exceeds price. Perfect competition is sometimes thought to have normative implications for political philosophy, since it results in Pareto optimality. The concept of perfect competition becomes extremely complicated when a market’s evolution is considered. Producers who cannot equate marginal cost with the market price will have negative profit and must drop out of the market. If this happens very often, then the number of producers will no longer be large enough to sustain perfect competition, so new producers will need to enter the market. 

perfectus – finitum – complete -- perfectionism, an ethical view according to which individuals and their actions are judged by a maximal standard of achievement  specifically, the degree to which they approach ideals of aesthetic, intellectual, emotional, or physical “perfection.” Perfectionism, then, may depart from, or even dispense with, standards of conventional morality in favor of standards based on what appear to be non-moral values. These standards reflect an admiration for certain very rare levels of human achievement. Perhaps the most characteristic of these standards are artistic and other forms of creativity; but they prominently include a variety of other activities and emotional states deemed “noble”  e.g., heroic endurance in the face of great suffering. The perfectionist, then, would also tend toward a rather non-egalitarian  even aristocratic  view of humankind. The rare genius, the inspired few, the suffering but courageous artist  these examples of human perfection are genuinely worthy of our estimation, according to this view. Although no fully worked-out system of “perfectionist philosophy” has been attempted, aspects of all of these doctrines may be found in such philosophers as Nietzsche. Aristotle, as well, appears to endorse a perfectionist idea in his characterization of the human good. Just as the good lyre player not only exhibits the characteristic activities of this profession but achieves standards of excellence with respect to these, the good human being, for Aristotle, must achieve standards of excellence with respect to the virtue or virtues distinctive of human life in general. 

peripatos at the lycaeum – Grice: “This is a common word, and while it does mean that, being a covered pathway, you are meant to walk about, it did not apply as per my type of identificatory reference, to Aristotle. It was that bit of the gym created by Pericle and iproved by Lycurgus in the ‘middle of nowhere’ mount of Licabetto. Aristotle may have chosen the site because Socrate, his tutor’s tutor, used to walk all the way form downtown to corrupt the athletes!” -- peripatetic – lycaeum -- School, also called Peripatos, the philosophical playgroup founded by Aristotle at the Lycaeum gymnasium in Athens. The derivation of ‘Peripatetic’ from the alleged Aristotelian custom of “walking about, “peripatein,” is, while colourful, wrong. ‘Peripatos’ is in Griceian a “covered walking hall” – which is among the facilities, “as the excavations show,” as Grice notes. A scholarch or head-master presided over roughly two classes of members. One is the “presbyteroi” or seniors, who have this or that teaching dutu, and the “neaniskoi” or juniors. Grice: “When Austin instituted the playgroup he saw himself as *the* presbyteros, while I, like the others, was a ‘neaniskos.”” No females were allowed, to avoid disruption. During Aristotle’s lifetime his own lectures, whether for the inner circle of the school (what Aristotle calls ‘the gown’) or for Athens (‘the town’) at large, are probably the key attraction and core activity. Given Aristotle’s celebrated knack for organizing group research projects, we may assume that Peripatetics spent much of their time working on their own specific assignments either at the swimming-pool library, or at some kind of repository for specimens used in zoological and botanical investigations. As a foreigner, Aristotle cannot possibly own any property in Athens. When he left  Athens (pretty much as when Austin died) Theophrastus of Eresus (pretty much like Grice did) succeeded him as scholarch. Theophrastus is s an able Aristotelian (whereas Grice started to criticise Austin) who wrote extensively on metaphysics, psychology, physiology, botany, ethics, politics, and the history of philosophy. With the help of the Peripatetic dictator Demetrius of Phaleron, Theophrastus was able to secure property rights over the physical facilities of the school. Under Theophrastus, the Peripatos continued to flourish and is said to have had 2,000 students. Theophrastus’s successor, Strato of Lampsakos, has much narrower interests and abandoned key Aristotelian tenets (such as the syllogism – “I won’t force Aristotle to teach me how to reason with a middle term in the middle!” – Diog. Laert. v. 673b-c. With Strato, a progressive decline set in, to which the moving of Aristotle’s swimming-pool library out of Athens (minus the swimming-pool) by Neleus of Skepsis, certainly contributed. By the first century B.C. the Peripatos had ceased to exist. “Philosophers of later periods sympathetic to Aristotle’s views have also been called Peripatetics; I fact, *I* have, by A. D. Code, of all people!” – Refs.: H. P. Grice, “How to become a Peripatetic – and not die in the attempt.”

idem: Grice: “A very, untranslatable Roman notion – no translation – but cf. ‘ipse,’ ‘same,’ self’, and ‘sameself,’ and Peano’s = may do.” personal identity: explored by H. P. Grice in “Personal Identity,” Mind – and H. P. Grice, “The logical construction theory of personal identity,” and “David Hume on the vagaries of personal identity.” -- the numerical identity over time of persons. The question of what personal identity consists in is the question of what it is what the necessary and sufficient conditions are for a person existing at one time and a person existing at another time to be one and the same person. Here there is no question of there being any entity that is the “identity” of a person; to say that a person’s identity consists in such and such is just shorthand for saying that facts about personal identity, i.e., facts to the effect that someone existing at one time is the same as someone existing at another time, consist in such and such. This should not be confused with the usage, common in ordinary speech and in psychology, in which persons are said to have identities, and, sometimes, to seek, lose, or regain their identities, where one’s “identity” intimately involves a set of values and goals that structure one’s life. The words ‘identical’ and ‘same’ mean nothing different in judgments about persons than in judgments about other things. The problem of personal identity is therefore not one of defining a special sense of ‘identical,’ and it is at least misleading to characterize it as defining a particular kind of identity. Applying Quine’s slogan “no entity without identity,” one might say that characterizing any sort of entity involves indicating what the identity conditions for entities of that sort are so, e.g., part of the explanation of the concept of a set is that sets having the same members are identical, and that asking what the identity of persons consists in is just a way of asking what sorts of things persons are. But the main focus in traditional discussions of the topic has been on one kind of identity judgment about persons, namely those asserting “identity over time”; the question has been about what the persistence of persons over time consists in. What has made the identity persistence of persons of special philosophical interest is partly its epistemology and partly its connections with moral and evaluative matters. The crucial epistemological fact is that persons have, in memory, an access to their own past histories that is unlike the access they have to the histories of other things including other persons; when one remembers doing or experiencing something, one normally has no need to employ any criterion of identity in order to know that the subject of the remembered action or experience is i.e., is identical with oneself. The moral and evaluative matters include moral responsibility someone can be held responsible for a past action only if he or she is identical to the person who did it and our concern for our own survival and future well-being since it seems, although this has been questioned, that what one wants in wanting to survive is that there should exist in the future someone who is identical to oneself. The modern history of the topic of personal identity begins with Locke, who held that the identity of a person consists neither in the identity of an immaterial substance as dualists might be expected to hold nor in the identity of a material substance or “animal body” as materialists might be expected to hold, and that it consists instead in “same consciousness.” His view appears to have been that the persistence of a person through time consists in the fact that certain actions, thoughts, experiences, etc., occurring at different times, are somehow united in memory. Modern theories descended from Locke’s take memory continuity to be a special case of something more general, psychological continuity, and hold that personal identity consists in this. This is sometimes put in terms of the notion of a “person-stage,” i.e., a momentary “time slice” of the history of a person. A series of person-stages will be psychologically continuous if the psychological states including memories occurring in later members of the series grow out of, in certain characteristic ways, those occurring in earlier members of it; and according to the psychological continuity view of personal identity, person-stages occurring at different times are stages of the same person provided they belong to a single, non-branching, psychologically continuous series of person-stages. Opponents of the Lockean and neo-Lockean psychological continuity view tend to fall into two camps. Some, following Butler and Reid, hold that personal identity is indefinable, and that nothing informative can be said about what it consists in. Others hold that the identity of a person consists in some sort of physical continuity  perhaps the identity of a living human organism, or the identity of a human brain. In the actual cases we know about putting aside issues about non-bodily survival of death, psychological continuity and physical continuity go together. Much of the debate between psychological continuity theories and physical continuity theories has centered on the interpretation of thought experiments involving brain transplants, brain-state transfers, etc., in which these come apart. Such examples make vivid the question of whether our fundamental criteria of personal identity are psychological, physical, or both. Recently philosophical attention has shifted somewhat from the question of what personal identity consists in to questions about its importance. The consideration of hypothetical cases of “fission” in which two persons at a later time are psychologically continuous with one person at an earlier time has suggested to some that we can have survival  or at any rate what matters in survival  without personal identity, and that our self-interested concern for the future is really a concern for whatever future persons are psychologically continuous with us. 

phantasia: Grice: “ “Phantasia,” as any Clifton schoolboy knows, is cognate with ‘phainomenon,’ as Cant forgot!” -- Grecian, ‘appearance’, ‘imagination’, 1 the state we are in when something appears to us to be the case; 2 the capacity in virtue of which things appear to us. Although frequently used of conscious and imagistic experiences, ‘phantasia’ is not limited to such states; in particular, it can be applied to any propositional attitude where something is taken to be the case. But just as the English ‘appears’ connotes that one has epistemic reservations about what is actually the case, so ‘phantasia’ suggests the possibility of being misled by appearances and is thus often a subject of criticism. According to Plato, phantasia is a “mixture” of sensation and belief; in Aristotle, it is a distinct faculty that makes truth and falsehood possible. The Stoics take a phantasia to constitute one of the most basic mental states, in terms of which other mental states are to be explained, and in rational animals it bears the propositional content expressed in language. This last use becomes prominent in ancient literary and rhetorical theory to designate the ability of language to move us and convey subjects vividly as well as to range beyond the bounds of our immediate experience. Here lie the origins of the modern concept of imagination although not the Romantic distinction between fancy and imagination. Later Neoplatonists, such as Proclus, take phantasia to be necessary for abstract studies such as geometry, by enabling us to envision spatial relations. 

phenomenalism: one of the twelve labours of H. P. Grice – very fashionable at Oxford – “until Austin demolished it with his puritanical “Sense and sensibilia,” – Grice: “Strictly, it should be ‘sense and sensibile,’ since ‘sensibilia’ is plural – which invokes Ryle’s paradox of the speckled hen!” -- the view that propositions asserting the existence of physical objects are equivalent in meaning to propositions asserting that subjects would have certain sequences of sensations were they to have certain others. The basic idea behind phenomenalism is compatible with a number of different analyses of the self or conscious subject. A phenomenalist might understand the self as a substance, a particular, or a construct out of actual and possible experience. The view also is compatible with any number of different analyses of the visual, tactile, auditory, olfactory, gustatory, and kinesthetic sensations described in the antecedents and consequents of the subjunctive conditionals that the phenomenalist uses to analyze physical object propositions as illustrated in the last paragraph. Probably the most common analysis of sensations adopted by traditional phenomenalists is a sense-datum theory, with the sense-data construed as mind-dependent entities. But there is nothing to prevent a phenomenalist from accepting an adverbial theory or theory of appearing instead. The origins of phenomenalism are difficult to trace, in part because early statements of the view were usually not careful. In his Dialogues, Berkeley hinted at phenomenalism when he had Philonous explain how he could reconcile an ontology containing only minds and ideas with the story of a creation that took place before the existence of people. Philonous imagines that if he had been present at the creation he should have seen things, i.e., had sensations, in the order described in the Bible. It can also be argued, however, that J. S. Mill in An Examination of Sir William Hamilton’s Philosophy was the first to put forth a clearly phenomenalistic analysis when he identified matter with the “permanent possibility of sensation.” When Mill explained what these permanent possibilities are, he typically used conditionals that describe the sensations one would have if one were placed in certain conditions. The attraction of classical phenomenalism grew with the rise of logical positivism and its acceptance of the verifiability criterion of meaning. Phenomenalists were usually foundationalists who were convinced that justified belief in the physical world rested ultimately on our noninferentially justified beliefs about our sensations. Implicitly committed to the view that only deductive and inductive inferences are legitimate, and further assuming that to be justified in believing one proposition P on the basis of another E, one must be justified in believing both E and that E makes P probable, the phenomenalist saw an insuperable difficulty in justifying belief in ordinary statements about the physical world given prevalent conceptions of physical petitio principii phenomenalism 663    663 objects. If all we ultimately have as our evidence for believing in physical objects is what we know about the occurrence of sensation, how can we establish sensation as evidence for the existence of physical objects? We obviously cannot deduce the existence of physical objects from any finite sequence of sensations. The sensations could, e.g., be hallucinatory. Nor, it seems, can we observe a correlation between sensation and something else in order to generate the premises of an inductive argument for the conclusion that sensations are reliable indicators of physical objects. The key to solving this problem, the phenomenalist argues, is to reduce assertions about the physical world to complicated assertions about the sequences of sensations a subject would have were he to have certain others. The truth of such conditionals, e.g., that if I have the clear visual impression of a cat, then there is one before me, might be mind-independent in the way in which one wants the truth of assertions about the physical world to be mind-independent. And to the phenomenalist’s great relief, it would seem that we could justify our belief in such conditional statements without having to correlate anything but sensations. Many philosophers today reject some of the epistemological, ontological, and metaphilosophical presuppositions with which phenomenalists approached the problem of understanding our relation to the physical world through sensation. But the argument that was historically most decisive in convincing many philosophers to abandon phenomenalism was the argument from perceptual relativity first advanced by Chisholm in “The Problem of Perception.” Chisholm offers a strategy for attacking any phenomenalistic analysis. The first move is to force the phenomenalist to state a conditional describing only sensations that is an alleged consequence of a physical object proposition. C. I. Lewis, e.g., in An Analysis of Knowledge and Valuation, claims that the assertion P that there is a doorknob before me and to the left entails C that if I were to seem to see a doorknob and seem to reach out and touch it then I would seem to feel it. Chisholm argues that if P really did entail C then there could be no assertion R that when conjoined with P did not entail C. There is, however, such an assertion: I am unable to move my limbs and my hands but am subject to delusions such that I think I am moving them; I often seem to be initiating a grasping motion but with no feeling of contacting anything. Chisholm argues, in effect, that what sensations one would have if one were to have certain others always depends in part on the internal and external physical conditions of perception and that this fact dooms any attempt to find necessary and sufficient conditions for the truth of a physical object proposition couched in terms that describe only connections between sensations. 

phenomenology – Grice: “Strictly, my area – the science of appearances!” -- referred ironically by J. L. Austin as “linguistic phenomenology,”—Austin only accepted public-school (“i. e. private-school) educated males at his Saturday mornings – “They share my dialect, unlike others.” --  in the twentieth century, the philosophy developed by Husserl and some of his followers. The term has been used since the mideighteenth century and received a carefully defined technical meaning in the works of both Kant and Hegel, but it is not now used to refer to a homogeneous and systematically developed philosophical position. The question of what phenomenology is may suggest that phenomenology is one among the many contemporary philosophical conceptions that have a clearly delineated body of doctrines and whose essential characteristics can be expressed by a set of wellchosen statements. This notion is not correct, however. In contemporary philosophy there is no system or school called “phenomenology,” characterized by a clearly defined body of teachings. Phenomenology is neither a school nor a trend in contemporary philosophy. It is rather a movement whose proponents, for various reasons, have propelled it in many distinct directions, with the result that today it means different things to different people. While within the phenomenological movement as a whole there are several related currents, they, too, are by no means homogeneous. Though these currents have a common point of departure, they do not project toward the same destination. The thinking of most phenomenologists has changed so greatly that their respective views can be presented adequately only by showing them in their gradual development. This is true not only for Husserl, founder of the phenomenological movement, but also for such later phenomenologists as Scheler, N. Hartmann, Heidegger, Sartre, and Merleau-Ponty. To anyone who studies the phenomenological movement without prejudice the differences among its many currents are obvious. It has been phenomenal property phenomenology 664    664 said that phenomenology consists in an analysis and description of consciousness; it has been claimed also that phenomenology simply blends with existentialism. Phenomenology is indeed the study of essences, but it also attempts to place essences back into existence. It is a transcendental philosophy interested only in what is “left behind” after the phenomenological reduction is performed, but it also considers the world to be already there before reflection begins. For some philosophers phenomenology is speculation on transcendental subjectivity, whereas for others it is a method for approaching concrete existence. Some use phenomenology as a search for a philosophy that accounts for space, time, and the world, just as we experience and “live” them. Finally, it has been said that phenomenology is an attempt to give a direct description of our experience as it is in itself without taking into account its psychological origin and its causal explanation; but Husserl speaks of a “genetic” as well as a “constitutive” phenomenology. To some people, finding such an abundance of ideas about one and the same subject constitutes a strange situation; for others it is annoying to contemplate the “confusion”; and there will be those who conclude that a philosophy that cannot define its own scope does not deserve the discussion that has been carried on in its regard. In the opinion of many, not only is this latter attitude not justified, but precisely the opposite view defended by Thevenaz should be adopted. As the term ‘phenomenology’ signifies first and foremost a methodical conception, Thevenaz argues that because this method, originally developed for a very particular and limited end, has been able to branch out in so many varying forms, it manifests a latent truth and power of renewal that implies an exceptional fecundity. Speaking of the great variety of conceptions within the phenomenological movement, Merleau-Ponty remarked that the responsible philosopher must recognize that phenomenology may be practiced and identified as a manner or a style of thinking, and that it existed as a movement before arriving at a complete awareness of itself as a philosophy. Rather than force a living movement into a system, then, it seems more in keeping with the ideal of the historian as well as the philosopher to follow the movement in its development, and attempt to describe and evaluate the many branches in and through which it has unfolded itself. In reality the picture is not as dark as it may seem at first sight. Notwithstanding the obvious differences, most phenomenologists share certain insights that are very important for their mutual philosophical conception as a whole. In this connection the following must be mentioned: 1 Most phenomenologists admit a radical difference between the “natural” and the “philosophical” attitude. This leads necessarily to an equally radical difference between philosophy and science. In characterizing this difference some phenomenologists, in agreement with Husserl, stress only epistemological issues, whereas others, in agreement with Heidegger, focus their attention exclusively on ontological topics. 2 Notwithstanding this radical difference, there is a complicated set of relationships between philosophy and science. Within the context of these relationships philosophy has in some sense a foundational task with respect to the sciences, whereas science offers to philosophy at least a substantial part of its philosophical problematic. 3 To achieve its task philosophy must perform a certain reduction, or epoche, a radical change of attitude by which the philosopher turns from things to their meanings, from the ontic to the ontological, from the realm of the objectified meaning as found in the sciences to the realm of meaning as immediately experienced in the “life-world.” In other words, although it remains true that the various phenomenologists differ in characterizing the reduction, no one seriously doubts its necessity. 4 All phenomenologists subscribe to the doctrine of intentionality, though most elaborate this doctrine in their own way. For Husserl intentionality is a characteristic of conscious phenomena or acts; in a deeper sense, it is the characteristic of a finite consciousness that originally finds itself without a world. For Heidegger and most existentialists it is the human reality itself that is intentional; as Being-in-the-world its essence consists in its ek-sistence, i.e., in its standing out toward the world. 5 All phenomenologists agree on the fundamental idea that the basic concern of philosophy is to answer the question concerning the “meaning and Being” of beings. All agree in addition that in trying to materialize this goal the philosopher should be primarily interested not in the ultimate cause of all finite beings, but in how the Being of beings and the Being of the world are to be constituted. Finally, all agree that in answering the question concerning the meaning of Being a privileged position is to be attributed to subjectivity, i.e., to that being which questions the Being of beings. Phenomenologists differ, however, the moment they have to specify what is meant by subjectivity. As noted above, whereas Husserl conceives it as a worldless monad, Heidegger and most later phenomenologists conceive it as being-in-the-world. Referring to Heidegger’s reinterpretation of his phenomenology, Husserl writes: one misinterprets my phenomenology backwards from a level which it was its very purpose to overcome, in other words, one has failed to understand the fundamental novelty of the phenomenological reduction and hence the progress from mundane subjectivity i.e., man to transcendental subjectivity; consequently one has remained stuck in an anthropology . . . which according to my doctrine has not yet reached the genuine philosophical level, and whose interpretation as philosophy means a lapse into “transcendental anthropologism,” that is, “psychologism.” 6 All phenomenologists defend a certain form of intuitionism and subscribe to what Husserl calls the “principle of all principles”: “whatever presents itself in ‘intuition’ in primordial form as it were in its bodily reality, is simply to be accepted as it gives itself out to be, though only within the limits in which it then presents itself.” Here again, however, each phenomenologist interprets this principle in keeping with his general conception of phenomenology as a whole. Thus, while phenomenologists do share certain insights, the development of the movement has nevertheless been such that it is not possible to give a simple definition of what phenomenology is. The fact remains that there are many phenomenologists and many phenomenologies. Therefore, one can only faithfully report what one has experienced of phenomenology by reading the phenomenologists.

Philo Judaeus, philosopher who composed the bulk of his work in the form of commentaries and discourses on Scripture. He made the first known sustained attempt to synthesize its revealed teachings with the doctrines of classical philosophy. Although he was not the first to apply the methods of allegorical interpretation to Scripture, the number and variety of his interpretations make Philo unique. With this interpretive tool, he transformed biblical narratives into Platonic accounts of the soul’s quest for God and its struggle against passion, and the Mosaic commandments into specific manifestations of general laws of nature. Philo’s most influential idea was his conception of God, which combines the personal, ethical deity of the Bible with the abstract, transcendentalist theology of Platonism and Pythagoreanism. The Philonic deity is both the loving, just God of the Hebrew Patriarchs and the eternal One whose essence is absolutely unknowable and who creates the material world by will from primordial matter which He creates ex nihilo. Besides the intelligible realm of ideas, which Philo is the earliest known philosopher to identify as God’s thoughts, he posited an intermediate divine being which he called, adopting scriptural language, the logos. Although the exact nature of the logos is hard to pin down  Philo variously and, without any concern for consistency, called it the “first-begotten Son of the uncreated Father,” “Second God,” “idea of ideas,” “archetype of human reason,” and “pattern of creation”  its main functions are clear: to bridge the huge gulf between the transcendent deity and the lower world and to serve as the unifying law of the universe, the ground of its order and rationality. A philosophical eclectic, Philo was unknown to medieval Jewish philosophers but, beyond his anticipations of Neoplatonism, he had a lasting impact on Christianity through Clement of Alexandria, Origen, and Ambrose. 

Filolao, pre-Socratic Grecian philosopher from Crotone in southern Italy, the first Pythagorean to write a book. The surviving fragments of it are the earliest primary texts for Pythagoreanism, but numerous spurious fragments have also been preserved. Philolaus’s book begins with a cosmogony and includes astronomical, medical, and psychological doctrines. His major innovation was to argue that the cosmos and everything in it is a combination not just of unlimiteds what is structured and ordered, e.g. material elements but also of limiters structural and ordering elements, e.g. shapes. These elements are held together in a harmonia fitting together, which comes to be in accord with perspicuous mathematical relationships, such as the whole number ratios that correspond to the harmonic intervals e.g. octave % phenotext Philolaus 1 : 2. He argued that secure knowledge is possible insofar as we grasp the number in accordance with which things are put together. His astronomical system is famous as the first to make the earth a planet. Along with the sun, moon, fixed stars, five planets, and counter-earth thus making the perfect number ten, the earth circles the central fire a combination of the limiter “center” and the unlimited “fire”. Philolaus’s influence is seen in Plato’s Philebus; he is the primary source for Aristotle’s account of Pythagoreanism.  H. P.

vita – vitalism philosophical biology: Grice, “What is ‘life’?” “How come the Grecians had two expressions for this: ‘zoon’ and ‘bios’?” “Why could the Romans just do with ‘vivere’?’ -- Grice liked to regard himself as a philosophical biologist, and indeed philosophical physiologist. bioethics, the subfield of ethics that concerns the ethical issues arising in medicine and from advances in biological science. One central area of bioethics is the ethical issues that arise in relations between health care professionals and patients. A second area focuses on broader issues of social justice in health care. A third area concerns the ethical issues raised by new biological knowledge or technology. In relations between health care professionals and patients, a fundamental issue is the appropriate role of each in decision making about patient care. More traditional views assigning principal decision-making authority to physicians have largely been replaced with ideals of shared decision making that assign a more active role to patients. Shared decision making is thought to reflect better the importance of patients’ self-determination in controlling their care. This increased role for patients is reflected in the ethical and legal doctrine of informed consent, which requires that health care not be rendered without the informed and voluntary consent of a competent patient. The requirement that consent be informed places a positive responsibility on health care professionals to provide their patients with the information they need to make informed decisions about care. The requirement that consent be voluntary requires that treatment not be forced, nor that patients’ decisions be coerced or manipulated. If patients lack the capacity to make competent health care decisions, e.g. young children or cognitively impaired adults, a surrogate, typically a parent in the case of children or a close family member in the case of adults, must decide for them. Surrogates’ decisions should follow the patient’s advance directive if one exists, be the decision the patient would have made in the circumstances if competent, or follow the patient’s best interests if the patient has never been competent or his or her wishes are not known. A major focus in bioethics generally, and treatment decision making in particular, is care at or near the end of life. It is now widely agreed that patients are entitled to decide about and to refuse, according to their own values, any lifesustaining treatment. They are also entitled to have desired treatments that may shorten their lives, such as high doses of pain medications necessary to relieve severe pain from cancer, although in practice pain treatment remains inadequate for many patients. Much more controversial is whether more active means to end life such as physician-assisted suicide and voluntary euthanasia are morally permissible in indibhavanga bioethics 88   88 vidual cases or justified as public policy; both remain illegal except in a very few jurisdictions. Several other moral principles have been central to defining professionalpatient relationships in health care. A principle of truth telling requires that professionals not lie to patients. Whereas in the past it was common, especially with patients with terminal cancers, not to inform patients fully about their diagnosis and prognosis, studies have shown that practice has changed substantially and that fully informing patients does not have the bad effects for patients that had been feared in the past. Principles of privacy and confidentiality require that information gathered in the professionalpatient relationship not be disclosed to third parties without patients’ consent. Especially with highly personal information in mental health care, or information that may lead to discrimination, such as a diagnosis of AIDS, assurance of confidentiality is fundamental to the trust necessary to a wellfunctioning professionalpatient relationship. Nevertheless, exceptions to confidentiality to prevent imminent and serious harm to others are well recognized ethically and legally. More recently, work in bioethics has focused on justice in the allocation of health care. Whereas nearly all developed countries treat health care as a moral and legal right, and ensure it to all their citizens through some form of national health care system, in the United States about 15 percent of the population remains without any form of health insurance. This has fed debates about whether health care is a right or privilege, a public or individual responsibility. Most bioethicists have supported a right to health care because of health care’s fundamental impact on people’s well-being, opportunity, ability to plan their lives, and even lives themselves. Even if there is a moral right to health care, however, few defend an unlimited right to all beneficial health care, no matter how small the benefit and how high the cost. Consequently, it is necessary to prioritize or ration health care services to reflect limited budgets for health care, and both the standards and procedures for doing so are ethically controversial. Utilitarians and defenders of cost-effectiveness analysis in health policy support using limited resources to maximize aggregate health benefits for the population. Their critics argue that this ignores concerns about equity, concerns about how health care resources and health are distributed. For example, some have argued that equity requires giving priority to treating the worst-off or sickest, even at a sacrifice in aggregate health benefits; moreover, taking account in prioritization of differences in costs of different treatments can lead to ethically problematic results, such as giving higher priority to providing very small benefits to many persons than very large but individually more expensive benefits, including life-saving interventions, to a few persons, as the state of Oregon found in its initial widely publicized prioritization program. In the face of controversy over standards for rationing care, it is natural to rely on fair procedures to make rationing decisions. Other bioethics issues arise from dramatic advances in biological knowledge and technology. Perhaps the most prominent example is new knowledge of human genetics, propelled in substantial part by the worldwide Human Genome Project, which seeks to map the entire human genome. This project and related research will enable the prevention of genetically transmitted diseases, but already raises questions about which conditions to prevent in offspring and which should be accepted and lived with, particularly when the means of preventing the condition is by abortion of the fetus with the condition. Looking further into the future, new genetic knowledge and technology will likely enable us to enhance normal capacities, not just prevent or cure disease, and to manipulate the genes of future children, raising profoundly difficult questions about what kinds of persons to create and the degree to which deliberate human design should replace “nature” in the creation of our offspring. A dramatic example of new abilities to create offspring, though now limited to the animal realm, was the cloning in Scotland in 7 of a sheep from a single cell of an adult sheep; this event raised the very controversial future prospect of cloning human beings. Finally, new reproductive technologies, such as oocyte egg donation, and practices such as surrogate motherhood, raise deep issues about the meaning and nature of parenthood and families.  Philosophical biology -- euthanasia, broadly, the beneficent timing or negotiation of the death of a sick person; more narrowly, the killing of a human being on the grounds that he is better off dead. In an extended sense, the word ‘euthanasia’ is used to refer to the painless killing of non-human animals, in our interests at least as much as in theirs. Active euthanasia is the taking of steps to end a person’s  especially a patient’s  life. Passive euthanasia is the omission or termination of means of prolonging life, on the grounds that the person is better off without them. The distinction between active and passive euthanasia is a rough guide for applying the more fundamental distinction between intending the patient’s death and pursuing other goals, such as the relief of her pain, with the expectation that she will die sooner rather than later as a result. Voluntary euthanasia is euthanasia with the patient’s consent, or at his request. Involuntary euthanasia is euthanasia over the patient’s objections. Non-voluntary euthanasia is the killing of a person deemed incompetent with the consent of someone  say a parent  authorized to speak on his behalf. Since candidates for euthanasia are frequently in no condition to make major decisions, the question whether there is a difference between involuntary and non-voluntary euthanasia is of great importance. Few moralists hold that life must be prolonged whatever the cost. Traditional morality forbids directly intended euthanasia: human life belongs to God and may be taken only by him. The most important arguments for euthanasia are the pain and indignity suffered by those with incurable diseases, the burden imposed by persons unable to take part in normal human activities, and the supposed right of persons to dispose of their lives however they please. Non-theological arguments against euthanasia include the danger of expanding the principle of euthanasia to an everwidening range of persons and the opacity of death and its consequent incommensurability with life, so that we cannot safely judge that a person is better off dead. H. P. Grice, “The roman problem: ‘vita’ for ‘bios’ and ‘zoe.’”

philosophism: birrellism – general refelction on life. Grice defines a philosopher as someone ‘addicted to general reflections on life,’ like Birrell did. f. paraphilosophy – philosophical hacks. “Austin’s expressed view -- the formulation of which no doubt involves some irony -- is that we ‘philosophical hacks’ spend the week making, for the benefit of our tutees, direct attacks on this or that philosophical issue, and that we need to be refreshed, at the week-end, by some suitably chosen ‘para-philosophy’ in which some non-philosophical conception is to be examined with the full rigour of the Austinian Code, with a view to an ultimate analogical pay-off (liable never to be reached) in philosophical currency.” His feeling of superiority as a philosopher is obvious in various fields. He certaintly would not get involved in any ‘empirical’ survey (“We can trust this, qua philosophers, as given.”) Grice held a MA (Lit. Hum.) – Literae Humaniores (Philosophy). So he knew what he was talking about. The curriculum was an easy one. He plays with the fact that empiricists don’t regard philosophy as a sovereign monarch: philosophia regina scientiarum, provided it’s queen consort. In “Conceptual analysis and the province of philosophy,” he plays with the idea that Philosophy is the Supreme Science. Grice was somewhat obsessed as to what ‘philosohical’ stood for, which amused the members of his play group! His play group once spends five weeks in an effort to explain why, sometimes, ‘very’ allows, with little or no change of meaning, the substitution of ‘highly’ (as in ‘very unusual’) and sometimes does not (as in ‘very depressed’ or ‘very wicked’); and we reached no conclusion. This episode was ridiculed by some as an ultimate embodiment of fruitless frivolity. But that response is as out of place as a similar response to the medieval question, ‘How many angels can dance on a needle’s point?’” A needless point?For much as this medieval question is raised in order to display, in a vivid way, a difficulty in the conception of an immaterial substance, so The Play Group discussion is directed, in response to a worry from me, towards an examination, in the first instance, of a conceptual question which is generally agreed among us to be a strong candidate for being a question which had no philosophical importance, with a view to using the results of this examination in finding a distinction between philosophically important and philosophically unimportant enquiries. Grice is fortunate that the Lit. Hum. programme does not have much philosophy! He feels free! In fact, the lack of a philosophical background is felt as a badge of honour. It is ‘too clever’ and un-English to ‘know’ things. A pint of philosophy is all Grice wanted. Figurative. This is Harvardite Gordon’s attempt to formulate a philosophy of the minimum fundamental ideas that all people on the earth should come to know. Reviewed by A. M. Honoré: Short measure. Gordon, a Stanley Plummer scholar, e: Bowdoin and Harvard, in The Eastern Gazette. Grice would exclaim: I always loved Alfred Brooks Gordon! Grice was slightly disapppointed that Gordon had not included the fundamental idea of implicaturum in his pint. Short measure, indeed. Grice gives seminars on Ariskant (“the first part of this individual interested some of my tutees; the second, others.” Ariskant philosophised in Grecian, but also in the pure Teutonic, and Grice collaborated with Baker in this area. Curiously, Baker majors in French and philosophy and does research at the Sorbonne. Grice would sometimes define ‘philoosphy.’ Oddly, Grice gives a nice example of ‘philosopher’ meaning ‘addicted to general, usually stoic, reflections about life.’ In the context where it occurs, the implicaturum is Stevensonian. If Stevenson says that an athlete is usually tall, a philosopher may occasionally be inclined to reflect about life in general, as a birrelist would. Grice’s gives an alternate meaning, intended to display circularity: ‘engaged in philosophical studies.’ The idea of Grice of philosophy is the one the Lit. Hum. instills.  It is a unique experience, unknown in the New World, our actually outside Oxford, or post-Grice, where a classicist is not seen as a philosopher. Once a tutorial fellow in philosophy (rather than classics) and later university lecturer in philosophy (rather than classics) strengthens his attachment. Grice needs to regarded by his tutee as a philosopher simpliciter, as oppoosed to a prof: the Waynflete is a metaphysician; the White is a moralist, the Wykeham a logician, and the Wilde a ‘mental’. For Grice’s “greatest living philosopher,” Heidegger, ‘philosophy’ is a misnomer. While philology merely discourses (logos) on love, the philosopher claims to be a wizard (sophos) of love. Liddell and Scott have “φιλοσοφία,” which they render as “love of knowledge, pursuit thereof, speculation,” “ἡ φ. κτῆσις ἐπιστήμης.” Then there’s “ἡ πρώτη φ.,” with striking originality, metaphysic, Arist. Metaph. 1026a24. Just one sense, but various ambiguities remain in ‘philosopher,’ as per Grice’s two  usages. As it happens, Grice is both addicted to general, usually stoic, speculations about life, and he is a member of The Oxford Philosophical Society.Refs.: The main sources in the Grice Papers are under series III, of the doctrines.

philosophia perennis: a supposed body of truths that appear in the writings of the great philosophers, or the truths common to opposed philosophical viewpoints. The term is derived from the title of a book De perenni philosophia published by Agostino Steuco of Gubbio in 1540. It suggests that the differences between philosophers are inessential and superficial and that the common essential truth emerges, however partially, in the major philosophical schools. Aldous Huxley employed it as a title. L. Lavelle, N. Hartmann, and K. Jaspers also employ the phrase. M. De Wulf and many others use the phrase to characterize Neo-Thomism as the chosen vehicle of essential philosophical truths. Refs.: H. P. Grice, “All that remains is mutability.”

philosophical anthropology: Grice hardly used ‘man,’ but preferred ‘human,’ and person. ‘Man’ is very English, and that may be the reason why latinate Grice avoided it! “Human” Grice thought cognate with “homo,” which rendered Grecian ‘anthropoos.’ “The Grecians and the Roamns distinguished between a generic ‘anthropoos,’ and the masculine ‘aner,’ Roman ‘vir.’ -- “What is man?” Grice: “I would distinguish between what is human, and what is person.” -- philosophical inquiry concerning human nature, often starting with the question of what generally characterizes human beings in contrast to other kinds of creatures and things. Thus broadly conceived, it is a kind of inquiry as old as philosophy itself, occupying philosophers from Socrates to Sartre; and it embraces philosophical psychology, the philosophy of mind, philosophy of action, and existentialism. Such inquiry presupposes no immutable “essence of man,” but only the meaningfulness of distinguishing between what is “human” and what is not, and the possibility that philosophy as well as other disciplines may contribute to our self-comprehension. It leaves open the question of whether other kinds of naturally occurring or artificially produced entity may possess the hallmarks of our humanity, and countenances the possibility of the biologically evolved, historically developed, and socially and individually variable character of everything about our attained humanity. More narrowly conceived, philosophical anthropology is a specific movement in recent European philosophy associated initially with Scheler and Helmuth Plessner, and subsequently with such figures as Arnold Gehlen, Cassirer, and the later Sartre. It initially emerged in Germany simultaneously with the existential philosophy of Heidegger and the critical social theory of the Frankfurt School, with which it competed as G. philosophers turned their attention to the comprehension of human life. This movement was distinguished from the outset by its attempt to integrate the insights of phenomenological analysis with the perspectives attainable through attention to human and comparative biology, and subsequently to social inquiry as well. This turn to a more naturalistic approach to the understanding of ourselves, as a particular kind of living creature among others, is reflected in the titles of the two works published in 8 that inaugurated the movement: Scheler’s Man’s Place in Nature and Plessner’s The Levels of the Organic and Man. For both Scheler and Plessner, however, as for those who followed them, our nature must be understood by taking further account of the social, cultural, and intellectual dimensions of human life. Even those like Gehlen, whose Der Mensch 0 exhibits a strongly biological orientation, devoted much attention to these dimensions, which our biological nature both constrains and makes possible. For all of them, the relation between the biological and the social and cultural dimensions of human life is a central concern and a key to comprehending our human nature. One of the common themes of the later philosophical-anthropological literature  e.g., Cassirer’s An Essay on Man 5 and Sartre’s Critique of Dialectical Reason 0 as well as Plessner’s Contitio Humana 5 and Gehlen’s Early Man and Late Culture 3  is the plasticity of human nature, made possible by our biological constitution, and the resulting great differences in the ways human beings live. Yet this is not taken to preclude saying anything meaningful about human nature generally; rather, it merely requires attention to the kinds of general features involved and reflected in human diversity and variability. Critics of the very idea and possibility of a philosophical anthropology e.g., Althusser and Foucault typically either deny that there are any such general features or maintain that there are none outside the province of the biological sciences to which philosophy can contribute nothing substantive. Both claims, however, are open to dispute; and the enterprise of a philosophical anthropology remains a viable and potentially significant one. Refs.: H. P. Grice, “Gehlen and the idea that man is sick – homo infirmus.”

vita – vitalism -- animatum – Grice: “The Romans saw a living body as the ‘animatum,’ since it’s the soul that makes a body a living thing --. So the idea of ‘vita’ is conceptually linked to that of a ‘soul.’ Grice was logically more interested in the verb, ‘vivere.’ “Most of Malcolm’s sophismata on ‘dreaming’ apply to ‘living,’ surely “I live” implicates that I live. Grice was fascinated by the fact that English ‘quick’ was cognate with Roman ‘vivere.’ “as it should,” because if it’s quick, it’s most certainly alive!”   Old English cwic "living, alive, animate," and figuratively, of mental qualities, "rapid, ready," from Proto-Germanic *kwikwaz (source also of Old Saxon and Old Frisian quik, Old Norse kvikr "living, alive," Dutch kwik "lively, bright, sprightly," Old High German quec "lively," German keck "bold"), from PIE root *gwei- "to live." Sense of "lively, swift" developed by late 12c., on notion of "full of life." NE swift or the now more common fast may apply to rapid motion of any duration, while in quick (in accordance with its original sense of 'live, lively') there is a notion of 'sudden' or 'soon over.' We speak of a fast horse or runner in a race, a quick starter but not a quick horse. A somewhat similar feeling may distinguish NHG schnell and rasch or it may be more a matter of local preference. [Carl Darling Buck, "A Dictionary of Selected Synonyms in the Principal Indo-European Languages," 1949] v. n. Sanscr. giv-, givami, live; Gr. βίος, life; Goth. quius, living; Germ. quicken; Engl. quick, to livebe alivehave life (syn. spiro). philosophical biology: v. H. P. Grice, “The roman problem: doing with ‘vivere’ for ‘zoe’ and bios’” -- vide: H. P. Grice, “Philosophical biology and philosophical psychology” -- the philosophy of science applied to biology. On a conservative view of the philosophy of science, the same principles apply throughout science. Biology supplies additional examples but does not provide any special problems or require new principles. For example, the reduction of Mendelian genetics to molecular biology exemplifies the same sort of relation as the reduction of thermodynamics to statistical mechanics, and the same general analysis of reduction applies equally to both. More radical philosophers argue that the subject matter of biology has certain unique features; hence, the philosophy of biology is itself unique. The three features of biology most often cited by those who maintain that philosophy of biology is unique are functional organization, embryological development, and the nature of selection. Organisms are functionally organized. They are capable of maintaining their overall organization in the face of fairly extensive variation in their envisonments. Organisms also undergo ontogenetic development resulting from extremely complex interactions between the genetic makeup of the organism and its successive environments. At each step, the course that an organism takes is determined by an interplay between its genetic makeup, its current state of development, and the environment it happens to confront. The complexity of these interactions produces the naturenurture problem. Except for human artifacts, similar organization does not occur in the non-living world. The species problem is another classic issue in the philosophy of biology. Biological species have been a paradigm example of natural kinds since Aristotle. According to nearly all pre-Darwinian philosophers, species are part of the basic makeup of the universe, like gravity and gold. They were held to be as eternal, immutable, and discrete as these other examples of natural kinds. If Darwin was right, species are not eternal. They come and go, and once gone can no more reemerge than Aristotle can once again walk the streets of Athens. Nor are species immutable. A sample of lead can be transmuted into a sample of gold, but these elements as elements remain immutable in the face of such changes. However, Darwin insisted that species themselves, not merely their instances, evolved. Finally, because Darwin thought that species evolved gradually, the boundaries between species are not sharp, casting doubt on the essentialist doctrines so common in his day. In short, if species evolve, they have none of the traditional characteristics of species. Philosophers and biologists to this day are working out the consequences of this radical change in our worldview. The topic that has received the greatest attention by philosophers of biology in the recent literature is the nature of evolutionary theory, in particular selection, adaptation, fitness, and the population structure of species. In order for selection to operate, variation is necessary, successive generations must be organized genealogically, and individuals must interact differentially with their environments. In the simplest case, genes pass on their structure largely intact. In addition, they provide the information necessary to produce organisms. Certain of these organisms are better able to cope with their environments and reproduce than are other organisms. As a result, genes are perpetuated differentially through successive generations. Those characteristics that help an organism cope with its environments are termed adaptations. In a more restricted sense, only those characteristics that arose through past selective advantage count as adaptations. Just as the notion of IQ was devised as a single measure for a combination of the factors that influence our mental abilities, fitness is a measure of relative reproductive success. Claims about the tautological character of the principle philosophical behaviorism philosophy of biology of the survival of the fittest stem from the blunt assertion that fitness just is relative reproductive success, as if intelligence just is what IQ tests measure. Philosophers of biology have collaborated with biologists to analyze the notion of fitness. This literature has concentrated on the role that causation plays in selection and, hence, must play in any adequate explication of fitness. One important distinction that has emerged is between replication and differential interaction with the environment. Selection is a function of the interplay between these two processes. Because of the essential role of variation in selection, all the organisms that belong to the same species either at any one time or through time cannot possibly be essentially the same. Nor can species be treated adequately in terms of the statistical covariance of either characters or genes. The populational structure of species is crucial. For example, species that form numerous, partially isolated demes are much more likely to speciate than those that do not. One especially controversial question is whether species themselves can function in the evolutionary process rather than simply resulting from it. Although philosophers of biology have played an increasingly important role in biology itself, they have also addressed more traditional philosophical questions, especially in connection with evolutionary epistemology and ethics. Advocates of evolutionary epistemology argue that knowledge can be understood in terms of the adaptive character of accurate knowledge. Those organisms that hold false beliefs about their environment, including other organisms, are less likely to reproduce themselves than those with more accurate beliefs. To the extent that this argument has any force at all, it applies only to humansized entities and events. One common response to evolutionary epistemology is that sometimes people who hold manifestly false beliefs flourish at the expense of those who hold more realistic views of the world in which we live. On another version of evolutionary epistemology, knowledge acquisition is viewed as just one more instance of a selection process. The issue is not to justify our beliefs but to understand how they are generated and proliferated. Advocates of evolutionary ethics attempt to justify certain ethical principles in terms of their survival value. Any behavior that increases the likelihood of survival and reproduction is “good,” and anything that detracts from these ends is “bad.” The main objection to evolutionary ethics is that it violates the isought distinction. According to most ethical systems, we are asked to sacrifice ourselves for the good of others. If these others were limited to our biological relatives, then the biological notion of inclusive fitness might be adequate to account for such altruistic behavior, but the scope of ethical systems extends past one’s biological relatives. Advocates of evolutionary ethics are hard pressed to explain the full range of behavior that is traditionally considered as virtuous. Either biological evolution cannot provide an adequate justification for ethical behavior or else ethical systems must be drastically reduced in their scope.

philosophical oeconomica: Grice: “The oikos is the house – and a house is not a home unless there’s a cat around.” -- the study of methodological issues facing positive economic theory and normative problems on the intersection of welfare economics and political philosophy. Methodological issues. Applying approaches and questions in the philosophy of science specifically to economics, the philosophy of economics explores epistemological and conceptual problems raised by the explanatory aims and strategy of economic theory: Do its assumptions about individual choice constitute laws, and do they explain its derived generalizations about markets and economies? Are these generalizations laws, and if so, how are they tested by observation of economic processes, and how are theories in the various compartments of economics  microeconomics, macroeconomics  related to one another and to econometrics? How are the various schools  neoclassical, institutional, Marxian, etc.  related to one another, and what sorts of tests might enable us to choose between their theories? Historically, the chief issue of interest in the development of the philosophy of economics has been the empirical adequacy of the assumptions of rational “economic man”: that all agents have complete and transitive cardinal or ordinal utility rankings or preference orders and that they always choose that available option which maximizes their utility or preferences. Since the actual behavior of agents appears to disconfirm these assumptions, the claim that they constitute causal laws governing economic behavior is difficult to sustain. On the other hand, the assumption of preference-maximizing behavior is indispensable to twentieth-century economics. These two considerations jointly undermine the claim that economic theory honors criteria on explanatory power and evidential probity drawn philosophy of economics philosophy of economics 669    669 from physical science. Much work by economists and philosophers has been devoted therefore to disputing the claim that the assumptions of rational choice theory are false or to disputing the inference from this claim to the conclusion that the cognitive status of economic theory as empirical science is thereby undermined. Most frequently it has been held that the assumptions of rational choice are as harmless and as indispensable as idealizations are elsewhere in science. This view must deal with the allegation that unlike theories embodying idealization elsewhere in science, economic theory gains little more in predictive power from these assumptions about agents’ calculations than it would secure without any assumptions about individual choice. Normative issues. Both economists and political philosophers are concerned with identifying principles that will ensure just, fair, or equitable distributions of scarce goods. For this reason neoclassical economic theory shares a history with utilitarianism in moral philosophy. Contemporary welfare economics continues to explore the limits of utilitarian prescriptions that optimal economic and political arrangements should maximize and/or equalize utility, welfare, or some surrogate. It also examines the adequacy of alternatives to such utilitarian principles. Thus, economics shares an agenda of interests with political and moral philosophy. Utilitarianism in economics and philosophy has been constrained by an early realization that utilities are neither cardinally measurable nor interpersonally comparable. Therefore the prescription to maximize and/or equalize utility cannot be determinatively obeyed. Welfare theorists have nevertheless attempted to establish principles that will enable us to determine the equity, fairness, or justice of various economic arrangements, and that do not rely on interpersonal comparisons required to measure whether a distribution is maximal or equal in the utility it accords all agents. Inspired by philosophers who have surrendered utilitarianism for other principles of equality, fairness, or justice in distribution, welfare economists have explored Kantian, social contractarian, and communitarian alternatives in a research program that cuts clearly across both disciplines. Political philosophy has also profited as much from innovations in economic theory as welfare economics has benefited from moral philosophy. Theorems from welfare economics that establish the efficiency of markets in securing distributions that meet minimal conditions of optimality and fairness have led moral philosophers to reexamine the moral status of free-market exchange. Moreover, philosophers have come to appreciate that coercive social institutions are sometimes best understood as devices for securing public goods  goods like police protection that cannot be provided to those who pay for them without also providing them to free riders who decline to do so. The recognition that everyone would be worse off, including free riders, were the coercion required to pay for these goods not imposed, is due to welfare economics and has led to a significant revival of interest in the work of Hobbes, who appears to have prefigured such arguments. 

philosophy of education: Grice: “To teach is not the opposite of learn, even if The Wind in The Willows thus suggests. – “ “To teach is etymologically, to ‘show, -- the ensign – To educate is of course to guide, to lead, to conduce. Grice: “I taught Peters all he needed to know about this!” -- a branch of philosophy concerned with virtually every aspect of the educational enterprise. It significantly overlaps other, more mainstream branches especially epistemology and ethics, but even logic and metaphysics. The field might almost be construed as a “series of footnotes” to Plato’s Meno, wherein are raised such fundamental issues as whether virtue can be taught; what virtue is; what knowledge is; what the relation between knowledge of virtue and being virtuous is; what the relation between knowledge and teaching is; and how and whether teaching is possible. While few people would subscribe to Plato’s doctrine or convenient fiction, perhaps in Meno that learning by being taught is a process of recollection, the paradox of inquiry that prompts this doctrine is at once the root text of the perennial debate between rationalism and empiricism and a profoundly unsettling indication that teaching passeth understanding. Mainstream philosophical topics considered within an educational context tend to take on a decidedly genetic cast. So, e.g., epistemology, which analytic philosophy has tended to view as a justificatory enterprise, becomes concerned if not with the historical origins of knowledge claims then with their genesis within the mental economy of persons generally  in consequence of their educations. And even when philosophers of education come to endorse something akin to Plato’s classic account of knowledge as justified true belief, they are inclined to suggest, then, that the conveyance of knowledge via instruction must somehow provide the student with the justification along with the true philosophy of education philosophy of education 670    670 belief  thereby reintroducing a genetic dimension to a topic long lacking one. Perhaps, indeed, analytic philosophy’s general though not universal neglect of philosophy of education is traceable in some measure to the latter’s almost inevitably genetic perspective, which the former tended to decry as armchair science and as a threat to the autonomy and integrity of proper philosophical inquiry. If this has been a basis for neglect, then philosophy’s more recent, postanalytic turn toward naturalized inquiries that reject any dichotomy between empirical and philosophical investigations may make philosophy of education a more inviting area. Alfred North Whitehead, himself a leading light in the philosophy of education, once remarked that we are living in the period of educational thought subject to the influence of Dewey, and there is still no denying the observation. Dewey’s instrumentalism, his special brand of pragmatism, informs his extraordinarily comprehensive progressive philosophy of education; and he once went so far as to define all of philosophy as the general theory of education. He identifies the educative process with the growth of experience, with growing as developing  where experience is to be understood more in active terms, as involving doing things that change one’s objective environment and internal conditions, than in the passive terms, say, of Locke’s “impression” model of experience. Even traditionalistic philosophers of education, most notably Maritain, have acknowledged the wisdom of Deweyan educational means, and have, in the face of Dewey’s commanding philosophical presence, reframed the debate with progressivists as one about appropriate educational ends  thereby insufficiently acknowledging Dewey’s trenchant critique of the meansend distinction. And even some recent analytic philosophers of education, such as R. S. Peters, can be read as if translating Deweyan insights e.g., about the aim of education into an analytic idiom. Analytic philosophy of education, as charted by Oxford philosopher R. S. Peters, Israel Scheffler, and others in the Anglo- philosophical tradition, has used the tools of linguistic analysis on a wide variety of educational concepts learning, teaching, training, conditioning, indoctrinating, etc. and investigated their interconnections: Does teaching entail learning? Does teaching inevitably involve indoctrinating? etc. This careful, subtle, and philosophically sophisticated work has made possible a much-needed conceptual precision in educational debates, though the debaters who most influence public opinion and policy have rarely availed themselves of that precisification. Recent work in philosophy of education, however, has taken up some major educational objectives  moral and other values, critical and creative thinking  in a way that promises to have an impact on the actual conduct of education. Philosophy of education, long isolated in schools of education from the rest of the academic philosophical community, has also been somewhat estranged from the professional educational mainstream. Dewey would surely have approved of a change in this status quo.  Refs.: H. P. Grice, “Peters and I.”

philosophical historian: philosophical historian – Grice as – longitudinal unity -- Danto, A. C. philosopher of art and art history who has also contributed to the philosophies of history, action, knowledge, science, and metaphilosophy. Among his influential studies in the history of philosophy are books on Nietzsche, Sartre, and  thought. Danto arrives at his philosophy of art through his “method of indiscernibles,” which has greatly influenced contemporary philosophical aesthetics. According to his metaphilosophy, genuine philosophical questions arise when there is a theoretical need to differentiate two things that are perceptually indiscernible  such as prudential actions versus moral actions Kant, causal chains versus constant conjunctions Hume, and perfect dreams versus reality Descartes. Applying the method to the philosophy of art, Danto asks what distinguishes an artwork, such as Warhol’s Brillo Box, from its perceptually indiscernible, real-world counterparts, such as Brillo boxes by Proctor and Gamble. His answer  his partial definition of art  is that x is a work of art only if 1 x is about something and 2 x embodies its meaning i.e., discovers a mode of presentation intended to be appropriate to whatever subject x is about. These two necessary conditions, Danto claims, enable us to distinguish between artworks and real things  between Warhol’s Brillo Box and Proctor and Gamble’s. However, critics have pointed out that these conditions fail, since real Brillo boxes are about something Brillo about which they embody or convey meanings through their mode of presentation viz., that Brillo is clean, fresh, and dynamic. Moreover, this is not an isolated example. Danto’s theory of art confronts systematic difficulties in differentiating real cultural artifacts, such as industrial packages, from artworks proper. In addition to his philosophy of art, Danto proposes a philosophy of art history. Like Hegel, Danto maintains that art history  as a developmental, progressive process  has ended. Danto believes that modern art has been primarily reflexive i.e., about itself; it has attempted to use its own forms and strategies to disclose the essential nature of art. Cubism and abstract expressionism, for example, exhibit saliently the two-dimensional nature of painting. With each experiment, modern art has gotten closer to disclosing its own essence. But, Danto argues, with works such as Warhol’s Brillo Box, artists have taken the philosophical project of self-definition as far as they can, since once an artist like Warhol has shown that artworks can be perceptually indiscernible from “real things” and, therefore, can look like anything, there is nothing further that the artist qua artist can show through the medium of appearances about the nature of art. The task of defining art must be reassigned to philosophers to be treated discursively, and art history  as the developmental, progressive narrative of self-definition  ends. Since that turn of events was putatively precipitated by Warhol in the 0s, Danto calls the present period of art making “post-historical.” As an art critic for The Nation, he has been chronicling its vicissitudes for a decade and a half. Some dissenters, nevertheless, have been unhappy with Danto’s claim that art history has ended because, they maintain, he has failed to demonstrate that the only prospects for a developmental, progressive history of art reside in the project of the self-definition of art. “There are two concerns by the philosopher with history – the history of philosophy as a philosophical discipline – and the philosophy of history per se. In the latter, in what way can we say that decapitation willed the death of Charles II?” – Refs.: H. P. Grice, “Philosophy’s Two Co-Ordinate Unities: Lat. and Long.,” “Kantotle or Ariskant? The Co-Ordinate Unity of Philosophy.” Grice is more interested in philosophical historiography than history itself! He makes some hypotheses about the movement he belonged to, and he hoped that what he had to say related to what he called Athenian dialectic! In stressing the ‘continuity,’ or unity, of philosophy both latitudinal and longidtudinal, Grice is inviting historiography as more than ancilla philosophiae. This at a time when analyticd philowophers, mainly in the New World, “where they really lack a history,” were propagating the slogan that to philosophise is NOT do to history of philosophy!” philosophy of history, the philosophical study of human history and of attempts to record and interpret it. ‘History’ in English and its equivalent in most modern European languages has two primary senses: 1 the temporal progression of large-scale human events and actions, primarily but not exclusively in the past; and 2 the discipline or inquiry in which knowledge of the human past is acquired or sought. This has led to two senses of ‘philosophy of history’, depending on which “history” has been the object of philosophers’ attentions. Philosophy of history in the first sense is often called substantive or speculative, and placed under metaphysics. Philosophy of history in the second sense is called critical or analytic and can be placed in epistemology. Substantive philosophy of history. In the West, substantive philosophy of history is thought to begin only in the Christian era. In the City of God, Augustine wonders why Rome flourished while pagan, yet fell into disgrace after its conversion to Christiantity. Divine reward and punishment should apply to whole peoples, not just to individuals. The unfolding of events in history should exhibit a plan that is intelligible rationally, morally, and for Augustine theologically. As a believer Augustine is convinced that there is such a plan, though it may not always be evident. In the modern period, philosophers such as Vico and Herder also sought such intelligibility in history. They also believed in a long-term direction or purpose of history that is often opposed to and makes use of the purposes of individuals. The most elaborate and best-known example of this approach is found in Hegel, who thought that the gradual realization of human freedom could be discerned in history even if much slavery, tyranny, and suffering are necessary in the process. Marx, too, claimed to know the laws  in his case economic  according to which history unfolds. Similar searches for overall “meaning” in human history have been undertaken in the twentieth century, notably by Arnold Toynbee 95, author of the twelve-volume Study of History, and Oswald Spengler 06, author of Decline of the West. But the whole enterprise was denounced by the positivists and neo-Kantians of the late nineteenth century as irresponsible metaphysical speculation. This attitude was shared by twentieth-century neopositivists and some of their heirs in the analytic tradition. There is some irony in this, since positivism, explicitly in thinkers like Comte and implicitly in others, involves belief in progressively enlightened stages of human history crowned by the modern age of science. Critical philosophy of history. The critical philosophy of history, i.e., the epistemology of historical knowledge, can be traced to the late nineteenth century and has been dominated by the paradigm of the natural sciences. Those in the positivist, neopositivist, and postpositivist tradition, in keeping with the idea of the unity of science, believe that to know the historical past is to explain events causally, and all causal explanation is ultimately of the same sort. To explain human events is to derive them from laws, which may be social, psychological, and perhaps ultimately biological and physical. Against this reductionism, the neo-Kantians and Dilthey argued that history, like other humanistic disciplines Geisteswissenschaften, follows irreducible rules of its own. It is concerned with particular events or developments for their own sake, not as instances of general laws, and its aim is to understand, rather than explain, human actions. This debate was resurrected in the twentieth century in the English-speaking world. Philosophers like Hempel and Morton White b.7 elaborated on the notion of causal explanation in history, while Collingwood and William Dray b.1 described the “understanding” of historical agents as grasping the thought behind an action or discovering its reasons rather than its causes. The comparison with natural science, and the debate between reductionists and antireductionists, dominated other questions as well: Can or should history be objective and valuefree, as science purportedly is? What is the significance of the fact that historians can never perceive the events that interest them, since they are in the past? Are they not limited by their point of view, their place in history, in a way scientists are not? Some positivists were inclined to exclude history from science, rather than make it into one, relegating it to “literature” because it could never meet the standards of objectivity and genuine explanation; it was often the anti-positivists who defended the cognitive legitimacy of our knowledge of the past. In the non-reductionist tradition, philosophers have increasingly stressed the narrative character of history: to understand human actions generally, and past actions in particular, is to tell a coherent story about them. History, according to W. B. Gallie b.2, is a species of the genus Story. History does not thereby become fiction: narrative remains a “cognitive instrument” Louis Mink, 183 just as appropriate to its domain as theory construction is to science. Nevertheless, concepts previously associated with fictional narratives, such as plot structure and beginning-middle-end, are seen as applying to historical narratives as well. This tradition is carried further by Hayden White b.8, who analyzes classical nineteenth-century histories and even substantive philosophies of history such as Hegel’s as instances of romance, comedy, tragedy, and satire. In White’s work this mode of analysis leads him to some skepticism about history’s capacity to “represent” the reality of the past: narratives seem to be imposed upon the data, often for ideological reasons, rather than drawn from them. To some extent White’s view joins that of some positivists who believe that history’s literary character excludes it from the realm of science. But for White this is hardly a defect. Some philosophers have criticized the emphasis on narrative in discussions of history, since it neglects search and discovery, deciphering and evaluating sources, etc., which is more important to historians than the way they “write up” their results. Furthermore, not all history is presented in narrative form. The debate between pro- and anti-narrativists among philosophers of history has its parallel in a similar debate among historians themselves. Academic history in recent times has seen a strong turn away from traditional political history toward social, cultural, and economic analyses of the human past. Narrative is associated with the supposedly outmoded focus on the doings of kings, popes, and generals. These are considered e.g. by the  historian Fernand Braudel, 285 merely surface ripples compared to the deeper-lying and slower-moving currents of social and economic change. It is the methods and concepts of the social sciences, not the art of the storyteller, on which the historian must draw. This debate has now lost some of its steam and narrative history has made something of a comeback among historians. Among philosophers Paul Ricoeur has tried to show that even ostensibly non-narrative history retains narrative features. Historicity. Historicity or historicality: Geschichtlichkeit is a term used in the phenomenological and hermeneutic tradition from Dilthey and Husserl through Heidegger and Gadamer to indicate an essential feature of human existence. Persons are not merely in history; their past, including their social past, figures in their conception of themselves and their future possibilities. Some awareness of the past is thus constitutive of the self, prior to being formed into a cognitive discipine. Modernism and the postmodern. It is possible to view some of the debates over the modern and postmodern in recent Continental philosophy as a new kind of philosophy of history. Philosophers like Lyotard and Foucault see the modern as the period from the Enlightenment and Romanticism to the present, characterized chiefly by belief in “grand narratives” of historical progress, whether capitalist, Marxist, or positivist, with “man” as the triumphant hero of the story. Such belief is now being or should be abandoned, bringing modernism to an end. In one sense this is like earlier attacks on the substantive philosophy of history, since it unmasks as unjustified moralizing certain beliefs about large-scale patterns in history. It goes even further than the earlier attack, since it finds these beliefs at work even where they are not explicitly expressed. In another sense this is a continuation of the substantive philosophy of history, since it makes its own grand claims about largescale historical patterns. In this it joins hands with other philosophers of our day in a general historicization of knowledge e.g., the philosophy of science merges with the history of science and even of philosophy itself. Thus the later Heidegger  and more recently Richard Rorty  view philosophy itself as a large-scale episode in Western history that is nearing or has reached its end. Philosophy thus merges with the history of philosophy, but only thanks to a philosophical reflection on this history as part of history as a whole. 

jus: prudentia iuris, iuris-prudentia, iurisprudentia -- Jurisprudence – Grice: “The root of ‘juris’ is an interesting one – before Hart and his legalese, it was all about ethics’!” The Roman expression ‘jus,’ not to be confused with ‘jus,’ which meant ‘juice,’ as in ‘orange juice,’ is kindred with Sanscrit, “yu,” to join; cf. ζεύγνυμι, and jungo, qs. the binding, obliging; in this way, it compares with “lex,” which derives from “ligo,” -- right, law, justice. The ‘jungo’ gives the family of expressions like ‘con-junctum,’ joined. The idea is that if you are bound, you are obliged.  -- Hartian jurisprudence – Grice on Hartian jurisprudence -- philosophy of law, also called general jurisprudence, the study of conceptual and theoretical problems concerning the nature of law as such, or common to any legal system. Problems in the philosophy of law fall roughly into two groups. The first contains problems internal to law and legal systems as such. These include a the nature of legal rules; the conditions under which they can be said to exist and to influence practice; their normative character, as mandatory or advisory; and the indeterminacy of their language; b the structure and logical character of legal norms; the analysis of legal principles as a class of legal norms; and the relation between the normative force of law and coercion; c the identity conditions for legal systems; when a legal system exists; and when one legal system ends and another begins; d the nature of the reasoning used by courts in adjudicating cases; e the justification of legal decisions; whether legal justification is through a chain of inferences or by the coherence of norms and decisions; and the relation between intralegal and extralegal justification; f the nature of legal validity and of what makes a norm a valid law; the relation between validity and efficacy, the fact that the norms of a legal system are obeyed by the norm-subjects; g properties of legal systems, including comprehensiveness the claim to regulate any behavior and completeness the absence of gaps in the law; h legal rights; under what conditions citizens possess them; and their analytical structure as protected normative positions; i legal interpretation; whether it is a pervasive feature of law or is found only in certain kinds of adjudication; its rationality or otherwise; and its essentially ideological character or otherwise. The second group of problems concerns the philosophy of law philosophy of law 676    676 relation between law as one particular social institution in a society and the wider political and moral life of that society: a the nature of legal obligation; whether there is an obligation, prima facie or final, to obey the law as such; whether there is an obligation to obey the law only when certain standards are met, and if so, what those standards might be; b the authority of law; and the conditions under which a legal system has political or moral authority or legitimacy; c the functions of law; whether there are functions performed by a legal system in a society that are internal to the design of law; and analyses from the perspective of political morality of the functioning of legal systems; d the legal concept of responsibility; its analysis and its relation to moral and political concepts of responsibility; in particular, the place of mental elements and causal elements in the assignment of responsibility, and the analysis of those elements; e the analysis and justification of legal punishment; f legal liberty, and the proper limits or otherwise of the intrusion of the legal system into individual liberty; the plausibility of legal moralism; g the relation between law and justice, and the role of a legal system in the maintenance of social justice; h the relation between legal rights and political or moral rights; i the status of legal reasoning as a species of practical reasoning; and the relation between law and practical reason; j law and economics; whether legal decision making in fact tracks, or otherwise ought to track, economic efficiency; k legal systems as sources of and embodiments of political power; and law as essentially gendered, or imbued with race or class biases, or otherwise. Theoretical positions in the philosophy of law tend to group into three large kinds  legal positivism, natural law, and legal realism. Legal positivism concentrates on the first set of problems, and typically gives formal or content-independent solutions to such problems. For example, legal positivism tends to regard legal validity as a property of a legal rule that the rule derives merely from its formal relation to other legal rules; a morally iniquitous law is still for legal positivism a valid legal rule if it satisfies the required formal existence conditions. Legal rights exist as normative consequences of valid legal rules; no questions of the status of the right from the point of view of political morality arise. Legal positivism does not deny the importance of the second set of problems, but assigns the task of treating them to other disciplines  political philosophy, moral philosophy, sociology, psychology, and so forth. Questions of how society should design its legal institutions, for legal positivism, are not technically speaking problems in the philosophy of law, although many legal positivists have presented their theories about such questions. Natural law theory and legal realism, by contrast, regard the sharp distinction between the two kinds of problem as an artifact of legal positivism itself. Their answers to the first set of problems tend to be substantive or content-dependent. Natural law theory, for example, would regard the question of whether a law was consonant with practical reason, or whether a legal system was morally and politically legitimate, as in whole or in part determinative of the issue of legal validity, or of whether a legal norm granted a legal right. The theory would regard the relation between a legal system and liberty or justice as in whole or in part determinative of the normative force and the justification for that system and its laws. Legal realism, especially in its contemporary politicized form, sees the claimed role of the law in legitimizing certain gender, race, or class interests as the prime salient property of law for theoretical analysis, and questions of the determinacy of legal rules or of legal interpretation or legal right as of value only in the service of the project of explaining the political power of law and legal systems.

Literae humaniores. Grice took ‘literature’ seriously. “After all, I am a Lit. Hum. master! And previously a Lit. Hum. BACHELOR” – He made a strict distinction, seeing that at Oxford, a master can do things a bachelor cannot – like marry! philosophy of literature: Grice: “When I got my Masters in Literae Humaniores, the more human letters, my mather said – which are the less human ones?” -- literary theory. However, while the literary theorist, who is often a literary critic, is primarily interested in the conceptual foundations of practical criticism, philosophy of literature, usually done by philosophers, is more often concerned to place literature in the context of a philosophical system. Plato’s dialogues have much to say about poetry, mostly by way of aligning it with Plato’s metaphysical, epistemological, and ethico-political views. Aristotle’s Poetics, the earliest example of literary theory in the West, is also an attempt to accommodate the practice of Grecian poets to Aristotle’s philosophical system as a whole. Drawing on the thought of philosophers like Kant and Schelling, Samuel Taylor Coleridge offers in his Biographia Literaria a philosophy of literature that is to Romantic poetics what Aristotle’s treatise is to classical poetics: a literary theory that is confirmed both by the poets whose work it legitimates and by the metaphysics that recommends it. Many philosophers, among them Hume, Schopenhauer, Heidegger, and Sartre, have tried to make room for literature in their philosophical edifices. Some philosophers, e.g., the G. Romantics, have made literature and the other arts the cornerstone of philosophy itself. See Philippe Lacoue-Labarthe and Jean-Luc Nancy, The Literary Absolute, 8. Sometimes ‘philosophy of literature’ is understood in a second sense: philosophy and literature; i.e., philosophy and literature taken to be distinct and essentially autonomous activities that may nonetheless sustain determinate relations to each other. Philosophy of literature, understood in this way, is the attempt to identify the differentiae that distinguish philosophy from literature and to specify their relationships to each other. Sometimes the two are distinguished by their subject matter e.g., philosophy deals with objective structures, literature with subjectivity, sometimes by their methods philosophy is an act of reason, literature the product of imagination, inspiration, or the unconscious, sometimes by their effects philosophy produces knowledge, literature produces emotional fulfillment or release, etc. Their relationships then tend to occupy the areas in which they are not essentially distinct. If their subject matters are distinct, their effects may be the same philosophy and literature both produce understanding, the one of fact and the other of feeling; if their methods are distinct, they may be approaching the same subject matter in different ways; and so on. For Aquinas, e.g., philosophy and poetry may deal with the same objects, the one communicating truth about the object in syllogistic form, the other inspiring feelings about it through figurative language. For Heidegger, the philosopher investigates the meaning of being while the poet names the holy, but their preoccupations tend to converge at the deepest levels of thinking. For Sartre, literature is philosophy engagé, existential-political activity in the service of freedom. ’Philosophy of literature’ may also be taken in a third sense: philosophy in literature, the attempt to discover matters of philosophical interest and value in literary texts. The philosopher may undertake to identify, examine, and evaluate the philosophical content of literary texts that contain expressions of philosophical ideas and discussions of philosophical problems  e.g., the debates on free will and theodicy in Fyodor Dostoevsky’s The Brothers Karamazov. Many if not most  courses on philosophy of literature are taught from this point of view. Much interesting and important work has been done in this vein; e.g., Santayana’s Three Philosophical Poets 0, Cavell’s essays on Emerson and Thoreau, and Nussbaum’s Love’s Knowledge 9. It should be noted, however, that to approach the matter in this way presupposes that literature and philosophy are simply different forms of the same content: what philosophy expresses in the form of argument literature expresses in lyric, dramatic, or narrative form. The philosopher’s treatment of literature implies that he is uniquely positioned to explicate the subject matter treated in both literary and philosophical texts, and that the language of philosophy gives optimal expression to a content less adequately expressed in the language of literature. The model for this approach may well be Hegel’s Phenomenology of Spirit, which treats art along with religion as imperfect adumbrations of a truth that is fully and properly articulated only in the conceptual mode of philosophical dialectic. Dissatisfaction with this presupposition and its implicit privileging of philosophy over literature has led to a different view of the relation between philosophy and literature and so to a different program for philosophy of literature. The self-consciously literary form of Kierkegaard’s writing is an integral part of his polemic against the philosophical imperialism of the Hegelians. In this century, the work of philosophers like Derrida and the philosophers and critics who follow his lead suggests that it is mistaken to regard philosophy and literature as alternative expressions of an identical content, and seriously mistaken to think of philosophy as the master discourse, the “proper” expression of a content “improperly” expressed in literature. All texts, on this view, have a “literary” form, the texts of philosophers as well as the texts of novelists and poets, and their content is internally determined by their “means of expression.” There is just as much “literature in philosophy” as there is “philosophy in literature.” Consequently, the philosopher of literature may no longer be able simply to extract philosophical matter from literary form. Rather, the modes of literary expression confront the philosopher with problems that bear on the presuppositions of his own enterprise. E.g., fictional mimesis especially in the works of postmodern writers raises questions about the possibility and the prephilosophy of literature philosophy of literature 678    678 philosophy of logic philosophy of logic 679 sumed normativeness of factual representation, and in so doing tends to undermine the traditional hierarchy that elevates “fact” over “fiction.” Philosophers’ perplexity over the truth-value of fictional statements is an example of the kind of problems the study of literature can create for the practice of philosophy see Rorty, Consequences of Pragmatism, 2, ch. 7. Or again, the self-reflexivity of contemporary literary texts can lead philosophers to reflect critically on their own undertaking and may seriously unsettle traditional notions of self-referentiality. When it is not regarded as another, attractive but perhaps inferior source of philosophical ideas, literature presents the philosopher with epistemological, metaphysical, and methodological problems not encountered in the course of “normal” philosophizing.
