From the bestselling author of The Man Who Mistook His Wife for a Hat, a collection of essays that displays Oliver Sacks's passionate engagement with the most compelling ideas of human endeavor: evolution, creativity, memory, time, consciousness, and experience. <p/>"Curious, avid and thrillingly fluent." --The New York Times Book Review <p/>In the pieces that comprise The River of Consciousness, Dr. Sacks takes on evolution, botany, chemistry, medicine, neuroscience, and the arts, and calls upon his great scientific and creative heroes--above all, Darwin, Freud, and William James. For Sacks, these thinkers were constant companions from an early age. The questions they explored--the meaning of evolution, the roots of creativity, and the nature of consciousness--lie at the heart of science and of this book. <p/>The River of Consciousness demonstrates Sacks's unparalleled ability to make unexpected connections, his sheer joy in knowledge, and his unceasing, timeless endeavor to understand what makes us human.
