Abstract
I highly recommend Philosophy of Psychedelics by Chris Letheby (2021) to both the public and academics who want to dig deeper into the modern therapeutic science of psychedelics. In this piece, I will draw attention to key topics covered in the book that I judge as particularly compelling and likely to influence psychedelic therapy and our understanding of it going forward. Clearly, the importance of philosophy in the modern psychedelic therapy renaissance will increase, and Letheby’s Philosophy of Psychedelics will hold a place as a foundational work helping to shape this future.
