Note: Chapter 3 is the most technical and demanding chapter in A Place for Consciousness. It is intended primarily for graduate and professional level philosophers, and presupposes that the reader has some familiarity with many of the arguments and terms used. Therefore, discussion of this chapter is optional, and will be conducted concurrently with discussion of chapter 4. In this chapter, Rosenberg answers to various physicalist responses to the argument against physicalism. In particular, he considers appeals to a posteriori necessity, appeals to holism, and warnings about a greater absurdity, and argues at length that none of these is an adequate response to the antiphysicalist argument. Sorry about the brevity of this summary; I'll have a more detailed one up soon. For now, interested parties can nonetheless begin discussion of the chapter here.
