I picked this book up mostly to prepare for Ramachandran's latest book, "the tell-tale brain". Plus I absolutely loved "Phantoms in the brain." This book though, is very general and doesn't delve in-depth in anything, nor is it particularly engaging. It has a few good points, such as human beings being are as much a product of culture as of genes. This book is indeed very "brief" and exceptionally easy to read. It doesn't leave much of an imprint though, nor did I learn anything startling new, as I would have liked.
