Here are seven detailed and fascinating portraits of neurological patients, including a surgeon consumed by the compulsive tics of Tourette's syndrome unless he is operating; an artist who loses all sense of color in a car accident, but finds a new sensibility and creative power in black and white; and an autistic professor who cannot decipher the simplest social exchange between humans, but has built a career out of her intuitive understanding of animal behavior. Sacks combines the well honed mind of an academician with the verve of a true storyteller, and manages to produce a book at once accessible and challenging. The capacity to observe the patient as a different form of human being, instead of as just an 'interesting case', is a true insight into what Medicine should be; furthermore, as the author insistently teaches, neurological diseases differ from other ailments in that they become a true portion of the persona, and ,in a sense, they belong to the patient, whereas most people consider disease to be something that 'happens' to them, an outside influence not to be confused with the true Self. It is a truly accessible and moving book, and teaches us all something about the diversity and depths of the human kind.
