Christopher Beha grew up Catholic in Manhattan, walked away during the New Atheist era, and spent years trying to build a secular worldview sturdy enough to live inside. It didn't hold. So he kept reading—Hume, Kant, Russell, the existentialists—and kept chasing the questions that don't let you sleep: what counts as evidence, what belief even is, and what you do when reason can't answer the things you still have to decide.

In this conversation with Michael Shermer, Beha makes a case that skepticism and belief aren't enemies—and that some debates go nowhere because people are arguing about the "branches" while standing on totally different foundations.

Christopher Beha is the former editor of Harper's Magazine and the author of four previous books, including The Index of Self-Destructive Acts, which was nominated for the 2020 National Book Award. His new book is Why I Am Not an Atheist: The Confessions of a Skeptical Believer.
