The Island of the Colorblind

"An explorer of that most wondrous of islands, the human brain," writes D.M. Thomas in The New York Times Book Review, "Oliver Sacks also loves the oceanic kind of islands." Both kinds figure movingly in this book--part travelogue, part autobiography, part medical mystery story--in which Sacks's journeys to a tiny Pacific atoll and the island of Guam become explorations of the meaning of islands, the genesis of disease, the wonders of botany, the nature of deep geological time, and the complexities of being human.

Drawn to the Micronesian island of Pingelap by reports of a community of people born totally colorblind, Dr. Sacks set up a clinic in a one-room dispensary. There he listened to patients describe their colorless world in terms rich with pattern and tone, luminance and shadow. Then, in Guam, he investigated a puzzling neurodegenerative paralysis, making housecalls amid crowing cockerels, cycad jungles, and the remains of a colonial culture. The experience affords Sacks an opportunity to elaborate on such personal passions as botany and history and to explore the meaning of islands, the dissemination of species, the birth of disease, and the nature of deep geologic time.
