The mind's eye / Oliver Sacks.

Includes stories of people who are able to navigate the world and communicate with others despite losing what many of us consider indispensable senses and faculties: the power of speech, the capacity to recognize faces, the sense of three-dimensional space, the ability to read, and the sense of sight. This book is a testament to the complexity of vision and the brain and to the power of creativity and adaptation, and it provides a whole new perspective on the power of language and communication, as we try to imagine what it is to perceive through another person's eyes, or another person's mind.
