"In my view, this is an admirable book. It is concise, well organized, and clearly and vigorously written. It presents a real solution to a real and extremely important problem. It is perhaps the only solution to this problem that is currently available." Peter Van Inwagen, The Philosophical Review "Colin McGinn's thoughts about the nature and state of philosophical inquiry are lucid and suggestive, and, in my personal opinion, on the right track. They merit careful reading, and should place many of the fundamental questions of our intellectual tradition in a new and more wholesome light." Noam Chomsky, Massachusetts Institute of Technology
