ABSTRACT: Consensus has it that Putnam-Burge style arguments for content-externalism do not strengthen the case for vehicle-externalism, i.e., the thesis that some mental states include as their parts notebooks, iPhones, and other extra-bodily phenomena. Rowlands and Sprevak, among others, argue that vehicle-externalism gets stronger support from Clark and Chalmers’s parity principle and functionalism, generally. I contest this assessment and thereby give reason to reconsider the support that content-externalism provides the extended mind thesis: although content-externalism does not entail vehicle-externalism, as Rowlands argues, neither does functionalism. The functionalist cannot reject the content-externalist argument for vehicle-externalism on these grounds without undercutting her own.Export citation Request permission.

I present and evaluate the prospects of the biosemantic program, understood as a philosophical attempt to explain the mind’s origins by appealing to something that non-minded organisms and minded organisms have in common: representational capacity. I develop an analogy with ancient attempts to account for the origins of change, clarify the biosemantic program’s aims and methods, and then distinguish two importantly different forms of objection, a priori and a posteriori. I defend the biosemantic program from a priori objections on the grounds that the standard of explanation presupposed by them is inappropriate and leads to absurdities if consistently applied. Once the way is cleared of a priori objections, the success of biosemantics turns on the strength of a posteriori objections, that is, on the program’s empirical adequacy. Here, its prospects are less clear, but I offer reasons, by analogy with chemical combination and other everyday phenomena, to think that minded beings and their representational capacities might well have their origin and explanation in non-minded beings. An evolutionary origin and explanation of mind is plausible, at least as far as naturalistic accounts and explanations go.

I describe and articulate the merits of an elegant supplemental exercise that I call “Philosophy in the Wild” (PW), which has students initiating a philosophical dialogue outside the classroom and critically reflecting on the results. The PW exercise is especially effective if used to reinforce philosophic texts which have dialogue as their form or as their subject matter (or both)—for instance, Plato’s Apology and Meno. However, the PW exercise is also an engaging, effective way simply to introduce students to the practice and the value of philosophy.

Evolutionary theory has an unexpected application in philosophy of mind, where it is used by the so-called biosemantic program—also called the teleosemantic program— to account for the representational capacities of neural states and processes in a way that conforms to an overarching scientific naturalism. Biosemantic theories account for the representational capacities of neural states and processes by appealing in particular to their evolutionary function, as that function is determined by a process of natural selection. As a result, biosemantic theories have distinct advantages over other theories of mental representation—e.g., Fodor’s causal theory. Foremost among the advantages of biosemantic theories is their ability to account for the possibility of mental misrepresentation.
