"This book is the deepest, and at the same time the most commonsensical, approach to the problem of mind and thought that I have read. The approach is from the point of view of computer science, yet Baum has no illusions about the progress which has been made within that field. He presents the many technical advances which have been made -- the book will be enormously useful for this aspect alone -- but refuses to play down their glaring inadequacies. He also presents a road map for getting further and makes the case that many of the apparently 'deep' philosophical problems such as free will may simply evaporate when one gets closer to real understanding."
