Writer and cultural critic Erik Davis joins us to discuss his fascinating, often startling new book, High Weirdness: Drugs, Esoterica, and Visionary Experience in the Seventies. By connecting the strange experiences of three psychedelic philosophers (Philip K. Dick, Terence McKenna, and Robert Anton Wilson), Davis offers a narrative of the 1970s that goes beyond disco and sideburns, showing us a world of occult prophecies, paranoid conspiracies, and often drug-induced spiritual fuckery.
