A neuroanthropologist maps out a revolutionary new practice—Hedonic Engineering—that combines the best of neuroscience and optimal psychology. It’s an intensive program of breathing, movement, and sexuality that mends trauma, heightens inspiration and tightens connections—helping us wake up, grow up, and show up for a world that needs us all.

This is a book about a big idea. And the idea is this: Slowly over the past few decades, and now suddenly, all at once, we’re suffering from a collapse in Meaning. Fundamentalism and nihilism are filling that vacuum, with consequences that affect us all. In a world that needs us at our best, diseases of despair, tribalism, and disaster fatigue are leaving us at our worst.
