Tyler Burge's (1979) famous thought experiment concerning 'arthritis' is commonly assumed to show that all ascriptions of content to beliefs and other attitudes are dependent for their truth upon facts about the agent's social and linguistic environment. It is also commonly claimed that Burge's argument shows that Putnam's (1975) result regarding natural kind terms applies to all general terms whatever, and hence shows that all such terms have wide meanings.1 But I wish to show here, first, that neither Burge's initial thought experiment nor a second type of example that Burge describes supports either of these conclusions. Second, I will identify the proper conclusion to draw from Burge's discussion and show that this conclusion does not really pose a serious problem for individualism about the mental. And finally, I will argue that Burge's discussion does not in fact provide a conclusive reason for believing its proper conclusion.

In my 1991 paper, AAnti-Individualism and Privileged Access,@ I argued that externalism in the philosophy of mind is incompatible with the thesis that we have privileged , nonempirical access to the contents of our own thoughts.¹ One of the most interesting responses to my argument has been that of Martin Davies (1998, 2000, and Chapter _ above) and Crispin Wright (2000 and Chapter _ above), who describe several types of cases to show that warrant for a premise does not always transmit to a known deductive consequence of that premise, and who contend that this fact under-mines my argument for incompatibilism. I will try to show here that the Davies/Wright point about transmission of warrant does not adversely affect my argument.

In this admirable book, Scott Soames provides well defended answers to some of the most difficult and important questions in the philosophy of language, and he does so with characteristic thoroughness, clarity, and rigor. The book's title is appropriate, since it does indeed go ‘beyond rigidity’ in many ways. Among other things, Soames does the following in the course of the book. He persuasively argues that the main thesis of Kripke's Naming and Necessity—that ordinary names are rigid designators—can be extended to the more general thesis that simple proper names are synonymous with neither nonrigid nor rigidified descriptions, and so have no descriptive content whatever. He thoroughly defends and places in the context of a larger semantic theory the Millian thesis that the sole semantic contents of most proper names are the names' referents, so that sentences containing such names semantically express singular Russellian propositions. He provides and defends at length an innovative pragmatic account of why substitution of co-referring proper names in cognitive contexts intuitively fails to be truth preserving, even though it seems to follow from the Millian thesis that such substitution must be semantically valid. And he thoroughly and persuasively defends a semantic theory of natural kind terms that explains how, following Kripke and Putnam, theoretical identities involving such terms can express a posteriori necessities, even though on Soames's theory, and contrary to the Kripke-Putnam view, such terms are neither names of natural kinds nor rigid designators in any interesting sense.

1. The primary evidence and motivation for externalism in the philosophy of mind is provided by the semantic facts that support direct reference theories of names, indexi- cal pronouns, and natural kind terms. But many externalists have forgotten their sem- antic roots, or so I shall contend here. I have become convinced of this by a common reaction among externalists to the main argument of my 1991 paper AAnti-Individual- ism and Privileged Access.@ In that argument, I concluded that externalism is incompat- ible with the principle that we can have privileged, non-empirical knowledge of the contents of our own thoughts. The reaction in question amounts to a dismissive denial of one of my argument=s main premises. This premise, which I defended at length in the paper, is that an externalist thesis regarding a cognitive property should hold that possession of the property by a person _logically_, or _conceptually_, implies the existence of objects external to that person.
