A Mind-Blowing Conversation About Humanity | Michael Pollan

Michael Pollan has investigated the inner workings of the mind, including in his books “The Omnivore’s Dilemma,” about why we eat the way we do, and “How to Change Your Mind,” about the science and uses of psychedelic drugs. With a new book out this month, “A World Appears: A Journey Into Consciousness,” he has jumped into the deep end.

“The Interview” host David Marchese says the book is both a personal and expansive survey of questions around human consciousness — what it is, what causes it, what it’s for and what the possible answers might mean for how we choose to live. With the rise of artificial intelligence, as well as the relentless political pressure on our attention, those questions, already profound, are becoming only more urgent.
