Michael Pollan Explores Labyrinth of Consciousness in 'A World Appears'

What is consciousness for, and why did it evolve? Can we change our “default” consciousness? These are some of the questions that Michael Pollan says began to preoccupy him after his first psychedelic experience, which altered his ordinary consciousness so profoundly that he wanted to learn everything he could about the mysteries of sentience, thought and selfhood. We talk to him about what he uncovered and challenges of studying a phenomenon that he says we’ll never understand completely. Pollan’s new book is “A World Appears: A Journey Into Consciousness.” Guests: Michael Pollan, author, "A World Appears: A Journey Into Consciousness" - professor emeritus, UC Berkeley Graduate School of Journalism; his other books include "In Defense of Food," "The Omnivore's Dilemma" and "How to Change Your Mind."
