Michael Pollan, one of the nation’s most influential non-fiction writers and investigative journalists, is the author of nine previous bestselling books, including How to Change Your Mind; In Defense of Food; The Omnivore’s Dilemma; and The Botany of Desire. Today, hewill trace his six-year quest to solve the greatest mystery in nature: how, and why, are we conscious? That Odyssey, which he describes in his newest book, A World Appears: A Journey into Consciousness, is an enthralling tale that begins in a brain lab in Seattle, and ends, of all places, in a cave in the mountains of New Mexico, where he discovers that explaining consciousness may be less important than learning to practice it, fully, in our everyday lives.
