summaryMartin and Pfeifer have claimed“that the most typical characterizations of intentionality… all fail to distinguish … mental states from …dispositional physical states.”The evidence they present in support of this thesis is examined in the light of the possibility that what it shows is that intentionality is the mark, not of the mental, but of the dispositional. Of the five marks of intentionality they discuss a critical examination shows that three of them, Brentano's inexistence of the intentional object, Searle's directedness and (...) Anscombe's indeterminacy, are features which distinguish T‐inten Tional/dispositional The other two are either, as in the case of Chisholm's permissible falsity of a propositional attitude ascription, a feature of linguistic utterances too restricted in its scope to be of interest, or, as in the case of Frege's indirect reference/Quine's referential opacity, evidence that the S‐intenSional locution is a quotation either of what someone has said in the past or might be expected to say, if the question were to arise at some time in the future.

Martin and Pfeifer claim ‘that the most typical characterizations of intentionality’ proposed by philosophers are satisfied by physical dispositions. If that is correct, we must conclude either, as they do and as Mumford (this volume) does, that the philosophers are wrong and intentionality is something else or, as I do, that intentionality is what the philosophers say it is, in which case it is the mark, not of the mental, but of the dispositional; the intentionality of a disposition consists in (...) its being directed towards its future manifestations. Mumford objects that the notion of directedness is obscure and cannot in the light of Martin’s electro‐fink argument be elucidated by reference to what would happen if the conditions for its manifestation are satisfied. But Martin‘s argument rests on the mistaken assumption that causal conditionals, of which dispositional ascriptions are an instance, are of the form ‘If p then q’. (shrink)

It is argued that conceptual analysis as practiced by the philosophers of ordinary language, is an empirical procedure that relies on a version of Garfinkel's ethnomethodological experiment. The ethnomethodological experiment is presented as a procedure in which the existence and nature of a social norm is demonstrated by flouting the putative convention and observing what reaction that produces in the social group within which the convention is assumed to operate. Examples are given of the use of ethnomethodological experiments, both in (...) vivo and as a thought experiment, in order to demonstrate the existence of otherwise invisible conventions governing human social behavior. Comparable examples are cited from the writings of ordinary language philosophers of ethnomethodological thought experiments designed to demonstrate the existence of linguistic conventions. (shrink)

This is the one and only book by the pioneer of the identity theory of mind. The collection focuses on Place's philosophy of mind and his contributions to neighboring issues in metaphysics and epistemology. It includes an autobiographical essay as well as a recent paper on the function and neural location of consciousness.

There is an argument whichshows conclusively that if qualia are causallyimpotent we could have no possible grounds forbelieving that they exist. But if, as this argumentshows, qualia are causally potent with respect to thedescriptions we give of them, it is tolerably certainthat they are causally potent in other morebiologically significant respects. The empiricalevidence, from studies of the effect of lesions of thestriate cortex shows that what is missing inthe absence of visual qualia is the ability tocategorize sensory inputs in the (...) visual modality. This would suggest that the function of privateexperience is to supply what Broadbent callsthe evidence on which the categorization ofproblematic sensory inputs are based. At the sametime analysis of the causal relation shows that whatdifferentiates a causal relation from an accidentalspatio-temporal conjunction is the existence ofreciprocally related dispositional properties of theentities involved which combine to make it true thatif one member of the conjunction, the cause, had notexisted, the other, the effect, would not haveexisted. The possibility that qualia might bedispositional properties of experiences which, as itwere, supply the invisible glue that sticks cause toeffect in this case is examined, but finallyrejected.

The writer's 1956 contention that "the thesis that consciousness is a process in the brain is ... a reasonable scientific hypothesis" is contrasted with Davidson's a priori argument in 'Mental events' for the identity of propositional attitude tokens with some unspecified and imspecifiable brain state tokens. Davidson's argument is rejected primarily on the grounds that he has failed to establish his claim that there are and can be no psycho-physical bridge laws. The case forthe empirical nature of the issue between (...) the identity thesis and interactionism is re-stated in tiie light of an analysis of the causal relations involved. The same analysis is also used to demonstrate the incoherence of parallelism and epiphenomenalism as alternatives to interactionism. (shrink)

The analysis of mental concepts suggests that the distinctionbetween the mental and the nonmental is not ontologically fundamental,and that, whereas mental processes are one and the same things as thebrain processes with which they are correlated, dispositional mentalstates depend causally on and are, thus, ''''distinct existences'''' fromthe states of the brain microstructure with which ''they'' are correlated.It is argued that this difference in the relation between an entity andits composition/underlying structure applies across the board. allstuffs and processes are the same (...) thing as is described by a descriptionof their microstructure. In all cases where the manifestation of adisposition extends beyond the ''''skin'''' of the dispositional propertybearer, dispositions invariably depend causally on the structure,usually the microstructure, of the bearer.

Skinner has repeatedly asserted that he does not deny either the existence of private events or the possibility of studying them scientifically. But he has never explained how his position in this respect differs from that of the mentalist or provided a practical methodology for the investigation of private events within a radical behaviorist perspective. With respect to the first of these deficiencies, I argue that observation statements describing a public state of affairs in the common public environment of two (...) or more observers which those observers confirm as a correct description provide a far more objective and secure foundation for empirical knowledge than statements describing private events in the experience of a single individual. In the course of this argument, I also invoke Wittgenstein's (1953) demonstration — his 'private language argument' — of the incoherence of traditional subjective empiricism. Regarding the second deficiency, I argue that observation statements describing private events can serve as data for an objective study, provided that (a) the verbal behavior in which they consist and its context are objectively observed and recorded, and (b) an explanation is given of how this verbal behavior is generated by the events it reports.

For the past three decades linguistic theory has been based on the assumption that sentences are interpreted and constructed by the brain by means of computational processes analogous to those of a serial-digital computer. The recent interest in devices based on the neural network or parallel distributed processor (PDP) principle raises the possibility ("eliminative connectionism") that such devices may ultimately replace the S-D computer as the model for the interpretation and generation of language by the brain. An analysis of the (...) differences between the two models suggests that the effect of such a development would be to steer linguistic theory towards a return to the empiricism and behaviorism which prevailed before it was driven by Chomsky towards nativism and mentalism. Linguists, however, will not be persuaded to return to such a theory unless and until it can deal with the phenomenon of novel sentence construction as effectively as its nativist/mentalist rival.

The distinction that Skinner draws in his 'An operant analysis of problem solving' (1966, 1969, 1984) between 'rule-governed' and 'contingency-shaped' behaviour is arguably the most important single contribution to the theory of behaviour that he has made in a long and uniquely distinguished career. The concept of a 'rule' as a 'contingency-specifying' verbal formula which exercises 'stimulus control' over other aspects of the behaviour of a linguistically competent human being presents a formidable challenge to contemporary cognitive psychology in that the (...) Representation' and 'computation' of environmental contingencies is seen as confined to verbally controlled behaviour emitted by linguistically competent human subjects. It also suggests a way of filling a major gap in the account of language offered by Skinner in his earlier book Verbal Behaviour (1957), namely the lack of any account of how the speaker is able to use instructions to evoke behaviour which the listener never previously emitted and declarative sentences to convey information about contingencies which the listener has never previously encountered.

Linguistic Behaviorism (Place, 1996) is an attempt to reclaim for the behaviorist perspective two disciplines, linguistics and linguistic philosophy, most of whose practitioners have been persuaded by Chomsky's (1959) Review of B. F. Skinner's (1957) "Verbal Behavior" that behaviorism has nothing useful to contribute to the study of language. It takes as axiomatic (a) that the functional unit of language is the sentence, and (b) that sentences are seldom repeated word-for-word, but are constructed anew on each occasion of utterance out (...) of units, words, phrases and turns of phrase, that are repeated. On this view, the problem of discriminating the true from the false arises from the use of novel declarative sentences (statements) to depict or, to use Skinner's term, "specify" contingencies the like of which the listener need never have encountered and to which he would otherwise have no access. In such cases the listener needs to distinguish among the sentences he receives from other speakers between those where the situation depicted/specified corresponds to that which actually exists at the time and place specified in the sentence and are, therefore, true, and those to which no actual situation corresponds and which are, therefore, false.

The alternative offered by Professor Stemmer to cognitivist theories of the process whereby general terms acquire their meaning is criticised in its turn on the grounds that it presents an oversimplified view of the complex processes involved in the acquisition of word meanings.

A symbol is defined as a species of sign. The concept of a sign coincides with Skinner's (1938) concept of a discriminative stimulus. Symbols differ from other signs in five respects: (1) They are stimuli which the organism can both respond to and produce, either as a self-directed stimulus (as in thinking) or as a stimulus for another individual with a predictably similar response from the recipient in each case. (2) they act as discriminative stimuli for the same kind of (...) object for all members of the verbal community within which they function as a symbols; (3) they acquire their properties by virtue of arbitrary social convention rather than any natural and intrinsic connection between the sign and what it is a sign of; (4) competent members of the verbal community can both produce the appropriate symbol in response to a naturally occurring sign of the presence of the object or a sample of the kind of object which the symbol stands for and select the appropriate object when presented with the symbol; (5) they form stimulus equivalence classes of the kind demonstrated in the matching-to-sample task (Sidman, 1971; Sidman and Tailby, 1982) both with other symbols having the same meaning and, more important, with the naturally-occurring non-symbolic signs of the presence of the object or kind of object which the symbol stands for.
