“What can Mary know about the conscious experience of color from inside her black and white room, and what follows for the metaphysics of consciousness? Torin Alter gives a state-of-the-art analysis of these issues. He focuses especially on the crucial gap between structural and phenomenal aspects of reality, and articulates a powerful version of Russellian monism that traces this gap to a deep level of the physical world. Along the way he gives a definitive defense of anti-materialist arguments from  objections old and new, shedding new light on this crucial nexus between consciousness, knowledge, and reality.” –David Chalmers, New York University


The Matter of Consciousness is a thorough and comprehensive treatment of the knowledge argument, one of the most compelling and influential arguments against physicalism about consciousness. Torin Alter’s treatment of this argument and the objections that have been raised against it is unsurpassed in quality and clarity. This book is essential reading for anyone with a serious interest in the contemporary case against physicalism about the mind.” –Derk Pereboom, Cornell University
