Abstract

In this paper I discuss Heck�s (2007) new argument for content dualism. This argument is based on the claim that conceptual states, but not perceptual states, meet Evans�s Generality Constraint. Heck argues that this claim, together with the idea that the kind of content we should attribute to a mental state depends on which generalizations the state satisfies, implies that conceptual states and perceptual states have different kinds of contents. I argue, however, that it is unlikely that there is a plausible reading of the Generality Constraint under which it is non-trivially true both that conceptual states meet it and that perceptual states do not. Therefore, the soundness of Heck�s argument is dubious
