" Fascinating case studies, including one involving Sacks himself, regarding vision, perception and the brain. Sacks' own personal diary of the loss of one of his eyes is both fascinating and heartbreaking and clearly the most intense section of the book. My personal favorite section explores stereo vision and how an incredibly large percentage of the population probably doesn't have it and, even stranger, doesn't realize that they don't have it. Sacks can occasionally be a little dry and clinical but his subjects are so bizarre and fascinating that hyperbolic language would probably only get in the way. "
