Understanding consciousness is one of the central scientific challenges of our time. This book presents Andy Ross’ recent work and discusses a range of perspectives on the core issues. The chapters are based on texts written for a variety of occasions and audiences. Reading them in order, one senses a growing clarity in the articulation of the new ideas, some of which are deep and rather subtle, and glimpses the outlines of a dynamic field. Ross has taken pains to unify the collection and make the main thread clearly visible. His new ideas are of fundamental importance, and readers who grapple with them should gain insight that amply rewards the effort. J. Andrew Ross is a freelance philosopher and writer based in Germany.
