I critically explore various forms of the language of thought (LOT) hypothesis. Many considerations, including the complexity of representational content and the systematicity of language understanding, support the view that some, but not all, of our mental representations occur in a language. I examine several arguments concerning sententialism and the propositional attitudes, Fodor's arguments concerning infant and animal thought, and Fodor's argument for radical concept nativism and show that none of these considerations require us to postulate a LOT that is (...) innate or otherwise distinct from spoken languages. Instead, I suggest that we maintain the more conservative hypothesis, supported by introspection, that some of our thoughts occur in the languages that we speak. (shrink)

This book is a comprehensive exposition of the Transcendental Deduction of the Categories in both editions of Kant’s Critique of Pure Reason.

Fodor and others who think that scientific, computational psychology will vindicate commonsense belief-desire psychology have maintained that belief can be identified with the explicit storage of a token with appropriate content. I review and develop problems for the explicit storage view and show that a more plausible account identifies belief with the disposition to use a token with appropriate content in explicit reasoning and planning processes and as a basis for action. I argue that this type of inner disposition account (...) will also apply to most other common sense attitudes. The result is a realism about commonsense belief-desire psychology that is more modest than Fodor's: While such inner dispositions probably do exist, these states will probably not be the main focus of scientific psychological theories.

Fodor has argued that, because concept acquisition relies on the use of concepts already possessed by the learner, all concepts that cannot be definitionally reduced are innate. Since very few reductive definitions are available, it appears that most concepts are innate. After noting the reasons why we find such radical concept nativism implausible, I explicate Fodor's argument, showing that anyone who is committed to mentalistic explanation should take it seriously. Three attempts at avoiding the conclusion are examined and found to (...) be unsuccessful. I then present an alternative way around Fodor's nativism; I maintain that concepts at a given level of explanation can be semantically primitive, yet at least partially acquired if some of the conditions at a lower level of explanation that are responsible for the concept's presence are themselves acquired.

I propose, develop and defend the view that theories of meaning — for instance, a theory specifying the logical form or truth conditions of natural language sentences — should be naturalized to scientific psychological inquiry. This involves both psychologism — the claim that semantics characterizes psychological states — and scientific naturalism — the claim that semantics will depend on the data and theories of scientific psychology. I argue that scientific psychologism is more plausible than the traditional alternative, the view that (...) a theory of meaning is a priori. After defending scientific psychologism against several objections, I offer a speculative proposal that shows how a theory of meaning can be integrated into scientific psychology. (shrink)
