Abstract

What is, or what should be, a philosophy of psychedelics? This question has never been so broadly relevant, given the groundswell of mainstream interest and experimentation, scientific investigation, therapeutic trials, entrepreneurial enterprise, and decriminalization of natural psychedelics in several American states. Chris Letheby’s Philosophy of Psychedelics is the first monograph to apply the term as an unelaborated title that, with the backing of Oxford University Press, projects the authority of a wide-ranging academic urtext that could define a renewed and newly legitimate field of inquiry.
