Is linguistic meaning to be accounted for independently of the states of mind of language users, or can it only be explained in terms of them? If the latter, what account of the mental states in question avoids circularity? In this book Brian Loar offers a subtle and comprehensive theory that both preserves the natural priority of the mind in explanations of meaning, and gives an independent characterisation of its features. the nature of meaning and its relation to the mind (...) is probably the area of paramount concern among philosophers. The theory presented here, by its reach and substance and the thoroughness and sophistication of its development, makes a major contribution to the debate. (shrink)

Some of a person's mental states have the power to represent real and imagined states of affairs: they have semantic properties. What Minds Can Do has two goals: to find a naturalistic or non-semantic basis for the representational powers of a person's mind, and to show that these semantic properties are involved in the causal explanation of the person's behaviour. In the process, this 1997 book addresses issues that are central to much contemporary philosophical debate. It will be of interest (...) to a wide range of readers in philosophy of mind and of language, cognitive science, and psychology. (shrink)

In The Elm and the Expert (1994), Fodor rejects the notion of narrow content as superfluous. He envisions a scientific intentional psychology that adverts only to broad content properties in its explanations. I show that there has been no change in Fodor's treatment of Frege cases and cases involving the so‐called deferential concepts. And for good reason: his notion of narrow content (1985‐91) couldn't explain them. The only apparent change concerns his treatment of Twin Earth cases. However, I argue that (...) the notion of broad content that his purely informational semantics delivers is, in some interesting sense, equivalent to the mapping notion of narrow content he officially gave up. I also critically reconstruct the evolution of Fodor's thinking between 1980 and 1994. (shrink)

[This is an earlier (1997), much longer and more detailed version of my entry on LOTH in the _Stanford Encyclopedia of Philosophy_] The Language of Thought Hypothesis (LOTH) is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that (...) has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

It's an achievement of the last couple of decades that people who work in linguistic semantics and people who work in the philosophy of language have arrived at a friendly, de facto agreement as to their respective job descriptions. The terms of this agreement are that the semanticists do the work and the philosophers do the worrying. The semanticists try to construct actual theories of meaning (or truth theories, or model theories, or whatever) for one or another kind of expression (...) in one or another natural language; for example, they try to figure out how the temperature could be rising compatibly with the substitutivity of identicals. The philosophers, by contrast, keep an eye on the large, foundational issues, such as: what's the relation between sense and denotation; what's the relation between thought and language; whether translation is determinate; and whether life is like a fountain. Every now and then the philosophers and the semanticists are supposed to get together and compare notes on their respective progress. Or lack thereof. (shrink)

Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a "language of thought" (LOT). Some connectionists like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not (...) implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not "concatenative," hence "radically different" from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones.

A venerable view, still very much alive, holds that human action is to be explained at least in part in terms of beliefs and desires. Those who advocate the view expect that the psychological theory which explains human behavior will invoke the concepts of belief and desire in a substantive way. I will call this expectation the belief-desire thesis. Though there would surely be a quibble or a caveat here and there, the thesis would be endorsed by an exceptionally heterogeneous (...) collection of psychologists and philosophers ranging from Freud and Hume, to Thomas Szasz and Richard Brandt. Indeed, a number of philosophers have contended that the thesis, or something like it, is embedded in our ordinary, workaday concept of action. If they are right, and I think they are, then insofar as we use the concept of action we are all committed to the belief-desire thesis. My purpose in this paper is to explore the tension between the belief-desire thesis and a widely held assumption about the nature of explanatory psychological theories, an assumption that serves as a fundamental regulative principle for much of contemporary psychological theorizing. This assumption, which for want of a better term I will call the principle of psychological autonomy, will be the focus of the first of the sections below. In the second section I will elaborate a bit on how the belief-desire thesis is to be interpreted, and try to extract from it a principle that will serve as a premise in the argument to follow. In the third section I will set out an argument to the effect that large numbers of belief-desire explanations of action, indeed perhaps the bulk of such explanations, are incompatible with the principle of autonomy. Finally, in the last section, I will fend off a possible objection to my argument. In the process, I will try to make clear just why the argument works and what price we should have to pay if we were resolved to avoid its consequences. (shrink)

Many philosophers think that being in an intentional state is a matter of being related to a sentence in a mental language-a 'Language of Thought' (see especially Fodor 1975, 1987 Appendix; Field 1978). According to this view-which I shall call 'the LT hypothesis'-when anyone has a belief or a desire or a hope with a certain content, they have a sentence of this language, with that content, 'written' in their heads. The claim is meant quite literally: the mental representations that (...) make up the items of this language have semantic and syntactic properties. This is why, according to this view, cognitive psychology does, and should, treat that part of the mind which deals with intentional states as a semantic and a syntactic 'engine'. (shrink)

According to the Computational/Representational Theory of Thought (CRTT ? Language of Thought Hypothesis, or LOTH), propositional attitudes, such as belief, desire, and the like, are triadic relations among subjects, propositions, and internal mental representations. These representations form a representational _system_ physically realized in the brain of sufficiently sophisticated cognitive organisms. Further, this system of representations has a combinatorial syntax and semantics, but the processes that operate on the representations are causally sensitive only to their syntax, not to their semantics. On (...) this approach, a first pass account of propositional attitudes is the following (cf. Field 1978: 37 and Fodor 1987: 17). (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

Written in a highly readable, irreverent style, The Elm and the Expert provides a lively discussion of semantic issues about mental representation, with special attention to issues raised by Frege's problem, Twin cases, and the putative indeterminacy of reference. Bound to be widely read and much discussed, The Elm and the Expert, written in Jerry Fodor's usual highly readable, irreverent style, provides a lively discussion of semantic issues about mental representation, with special attention to issues raised by Frege's problem, Twin (...) cases, and the putative indeterminacy of reference. The book extends and revises a view of the relation between mind and meaning that the author has been developing since his 1975 book, The Language of Thought. There is a general consensus among philosophers that a referential semantics for mental representation cannot support a robust account of intentional explanation. Fodor has himself espoused this view in previous publications, and it is widespread (if tacit) throughout the cognitive science community. This book is largely a reconsideration of the arguments that are supposed to ground this consensus. Fodor concludes that these considerations are far less decisive than has been supposed. He offers a theory sketch in which psychological explanation is intentional, psychological processes are computational, and the semantic properties of mental representations are referential. Connections with the problem of "naturalizing" intentionality are also explored. The four lectures in The Elm and the Expert were originally delivered in Paris in the spring of 1993 to inaugurate the Jean Nicod Lecture series. The Jean Nicod Lectures are delivered annually by a leading philosopher of mind or philosophically oriented cognitive scientist. The 1993 lectures marked the centenary of the birth of the French philosopher and logician Jean Nicod (1893-1931). The lectures are sponsored by the Centre National de la Recherche Scientifique (CNRS) as part of its effort to develop the interdisciplinary field of cognitive science in France. Jean Nicod series.

The paper explores the distinction between two doctrines, both of which inform theory construction in much of modern cognitive psychology: the representational theory of mind and the computational theory of mind. According to the former, propositional attitudes are to be construed as relations that organisms bear to mental representations. According to the latter, mental processes have access only to formal (nonsemantic) properties of the mental representations over which they are defined.The following claims are defended: (1) That the traditional dispute between (...) “rational” and “naturalistic” psychology is plausibly viewed as an argument about the status of the computational theory of mind. Rational psychologists accept a formality condition on the specification of mental processes; naturalists do not. (2) That to accept the formality condition is to endorse a version of methodological solipsism. (3) That the acceptance of some such condition is warranted, at least for that part of psychology which concerns itself with theories of the mental causation of behavior. This is because: (4) such theories require nontransparent taxonomies of mental states; and (5) nontransparent taxonomies individuate mental states without reference to their semantic properties. Equivalently, (6) nontransparent taxonomies respect the way that the organism represents the object of its propositional attitudes toitself, and it is this representation which functions in the causation of behavior.The final section of the paper considers the prospect for a naturalistic psychology: one which defines its generalizations over relations between mental representations and their environmental causes, thus seeking to account for the semantic properties of propositional attitudes. Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)

In this foundational work on the theory of linguistic and mental representation, Stephen Schiffer surveys all the leading theories of meaning and content in the philosophy of language and finds them lacking. He concludes that there can be no correct, positive philosophical theory or linguistic or mental representation and, accordingly advocates the deflationary "no-theory theory of meaning and content." Along the way he takes up functionalism, the nature of propositions and their suitability as contents, the language of thought and other (...) sententialist theories of belief, intention based semantics, and related issues in ontology.

Two naturalistic explications of propositional attitudes and their contents are distinguished: the language of thought based theory, on which beliefs are relations to sentences in the language of thought; and the propositional attitude based theory, on which beliefs are functional states of a functional system that does not imply a language of thought, although consistent with it. The latter theory depends on interpersonally ascribable conceptual roles; if these are not available, the language of thought theory has the advantage. But the (...) propositional attitude based theory explains intentionality and conceptual structure as well as the language of thought based theory, and it has two further advantages. First, it does not make the existence of beliefs and desires depend on the language of thought hypothesis. Secondly, its employment of interpersonally ascribable conceptual roles permits a theory of truth conditions to meet certain desiderata, such as a social basis for truth conditions, and a realist conception of truth.

It is argued that Loar's paper overestimates the importance of the distinction between 'functionalist' and 'representationalist' theories of the propositional attitudes; specifically, that the only version of functionalism which appears likely to provide an adequate account of the attitudes is one which treats them as relations to mental representations. The paper ends with a brief discussion of some of Loar's objection to 'ideal indicator' theories of the relation between beliefs and their truth conditions. It is argued that these objections are (...) not decisive. (shrink)
