Abstract

In 'kripke's argument against the identity theory' michael levin argues that the private language argument can be used to undermine saul kripke's cartesian claim to be able to imagine mental states and brain states existing apart, and, thus, refute his argument for dualism. in this paper it is argued that levin's use of the private language argument relies implicitly upon the descriptivist theory of mental language, to which kripke has provided a plausible alternative, "viz"., the causal theory of reference. thus, using the private language argument in the way levin suggests begs the question against the cartesian line of argument.
