Engaging and funny cognitive scientist Paul Bloom's second book is a fascinating read. In it, he argues that we are wired to view the world as containing both bodies and souls. Bloom argues convincingly that it is for this reason, that even when the idea of psychophysical dualism clashes with our intellectual understanding of bodies and souls, we still maintain vestiges of a belief in the immaterial soul. His discussions of a huge range of fascinating issues make this book a must-read. Descartes' Baby is incredibly fun to read, and is smattered with bits of humor and amusing anecdotes about real children and adults. Indeed, one of the most humorous moments in this lively book is Bloom's account of a neuroscientist colleague's culinarily-motivated search for animals without a certain neural structure, because, he reasoned, animals without this certain structure surely didn't have consciousness and therefore we safe to eat. Another strength of the book is Bloom's treatment of disgust. His view is both interesting and nuanced and falls naturally from his argument that we are intuitive dualists at heart. Other high points are his discussion of art and forgery, and his quite funny discussion of humor. It's not often that I read nonfiction. Normally I find it either too pedantic or too technical and narrow in scope to appeal to an outsider. One of the tremendous strengths of this book is that someone without training in developmental psychology or philosophy can follow it with ease, while still finding it intellectually satisfying. This book is truly a gem -- both entertaining and important. It's a must-read for anyone who has ever wondered about human nature.
