This article focuses on David Chalmers's theory which promises to lead us toward a "scientific study" of mind and consciousness. It is a critique of the metaphysics that Chalmers has espoused to support his thesis; namely, property dualism which posits a dichotomy only at the level of properties and not at the level of things. I argue that Chalmers's version of property dualism, though it may avoid the difficulties associated with the Cartesian kind of dualism, has its own set of problems. Instead of bolstering, this faulty metaphysics only helps to undermine his claim of irreducibility of consciousness.
