Chalmers analyzes the mind-body problem in terms of that elusive relationship between the physical brain and conscious events. Focusing on subjective experience as such, he rejects all reductive (materialist) explanations for conscious experience in favor of a metaphysical framework supporting a strong form of property dualism. His theory is grounded in natural supervenience, the distinction between psychological and phenomenological properties of mind, and a novel view of the ontological status of consciousness itself. Chalmers uses thought experiments (e.g., zombie worlds, silicon chips, a global brain, and inverted spectra) and discusses such issues as causation, intentionality, and epiphenomenalism. Even so, the critical reader is left asking, How can physical facts be relevant to the emergence of consciousness beyond an evolutionary naturalist worldview. Ongoing neuroscience research may provide a sufficient explanation of consciousness within a materialistic framework. Nevertheless, as a scholarly contribution to modern philosophy, this is suitable for all academic and large public libraries.~ H. James Birx, Canisius Coll., Buffalo, N.Y.
