'The Man Who Mistook His Wife for a Hat' is a sensational book written by Oliver Sacks back in 1971, which has since been reprinted dozens of times in English alone, not to mention numerous translations. These stories tell of modern people struggling to overcome serious and unusual mental disorders and struggling to survive in conditions unimaginable for healthy people, as well as of mystics of the past, obsessed with visions that modern science diagnoses as manifestations of severe neuroses. Sacks explains the strange, elusive relationship between the brain and consciousness in an accessible, vivid, and engaging manner.
