The 20th Century has ended, and we can look back on this famous classic with perhaps a better perspective. It in its own way has moved mountains of ignorance. It brought life to not only the patients in the book, but millions of neurologically impared patients in the world. It explained, along with the great movie 'Awakenings', how one could live but not really have complete life. This is a tragedy the medical profession must continue to confront with better research and treatment. Oliver Sacks originally wanted to be a researcher, but it was not in his destiny. What he became, as documented in this book, was a unique facilitator of science. He became a truly unique being that has blessed our humanity.
