In his latest book, Michael Pollan expands the conversation he began in How to Change Your Mind by exploring one of science's greatest mysteries: consciousness. Integrating insights from neuroscience, philosophy, artificial intelligence, spirituality, and psychedelic research, Pollan investigates competing theories of awareness while considering whether consciousness exists not only in humans, but also in animals, plants, and potentially AI. The result is a fascinating exploration of the nature of mind and what it means to be conscious.
