Brian has just written a NYT bestseller called "The Immortality Key," which explores the pivotal role that psychedelics may have played in forming Western civilization, first with the ancient Greeks and then early Christians.

I cannot recommend this book enough. Get full access to The Weekly Dish at andrewsullivan.substack.com/subscribe
