Oliver Sacks, neurologist and popularizer of the science of the mind, discusses his newest work, The Mind's Eye, in conversation with writer and editor Cullen Murphy.In The Mind's Eye, Oliver Sacks tells the stories of people who are able to navigate the world and communicate with others despite losing what many of us consider indispensable senses and abilities: the power of speech, the capacity to recognize faces, the sense of three-dimensional space, the ability to read, the sense of sight. For all of these people, the challenge is to adapt to a radically new way of being in the world.Sacks explores some very strange paradoxes--people who can see perfectly well but cannot recognize their own children, and blind people who become hyper--visual or who navigate by "tongue vision." He also considers more fundamental questions: How do we see? How do we think? How important is internal imagery--or vision, for that matter? Why is it that, although writing is only five thousand years old, humans have a universal, seemingly innate, potential for reading?
