Materialism in the philosophy of mind is the thesis that the ultimate nature of the mind is physical; there is no sharp discontinuity in nature between the mental and the non-mental. Anti-materialists asser t that, on the contrary, mental phenomena are different in kind from physical phenomena. Among the weapons in the arsenal of anti-materialists, one of the most potent has been the conceivability argument. When I conceive of the mental, it seems utterly unlike the physical. Anti-materialists insist that from this intuitive difference we can infer a genuine meta-physical difference. Materialists retor t that the nature of reality, including the ultimate natures of its constituents, is a matter for discovery; an objective fact that cannot be discerned a priori. In this paper I under take to provide an explicit analysis of the dialectic that surrounds the conceivability argument. My principal conclusion is that the materialist is right in resisting the reasoning that star ts from considerations of what is conceivable and ends with genuine metaphysical conclusions. However my approach is much more sympathetic to the anti-materialist position than is the standard materialist line, and I will provide a limited defense of some crucial aspects of the anti-materialist position. Materialism will emerge from this fight intact, but shaken.

This paper discusses the debate between atomists and molecularists regarding the nature of mental content. A molecularist believes that some, but not all, of a mental symbol's inferential connections to other mental symbols, are at least partly constitutive of that symbol's intentional content. An atomist believes that none of the symbol's inferential connections play such a constitutive role. The paper is divided into two principal parts. First, attempts by Michael Devitt and Georges Rey to defend molecularism against traditional Quinean arguments are evaluated. The conclusion is that their attempts fall short of providing an adequate defense. Second, the prospects for an atomistic theory are investigated, building on the various remarks of Fodor and LePore in their book. Holism: A Shopper's Guide. It is argued that the prospects are better than at first they appear.
