I have done considerable reading in my life and am an English major, (although an unconventional one) among other things. I had seen Oliver Sacks on TV where he was visiting people who were completely colorblind. The book was "The Island of the Colorblind". He also has written "The Man Who Mistook His Wife for a Hat". I have to say that Oliver Sacks has the most divinely articulate and sensitive writing style of anybody I have ever read. He is a doctor who apparently specializes in things like neurological problems. I do find investigations into the brain most fascinating. I would say one could not help but find his mind most pleasantly nourished by such a mind and style. Truly enlightened, and enlightening. Just pick up a book by Oliver Sacks and see where it leads you. A most rewarding adventure!
