Externalism and Token-Identity
This study has two goals. The first is to identify three desiderata required for a successful defense of a version of nonreductive physicalism: semantic externalism, token-identity between mental and
physical events, and nonrelational type-individuation of physical states. In this context, the paper also presents a refutation of recent challenges to content-externalism by those who attempt to resuscitate internalism by focusing on narrow content associated with the fundamental phenomenology, rather than the intentionality, of mental states. The second goal is to defend the token-identity thesis from Tyler Burge’s argument to the effect that token-identity is incompatible with semantic externalism. An account is also offered as to why Burge’s argument, albeit fallacious, might seem persuasive under a certain interpretation of possible worlds.
