Naturalistic Entheogenics: Précis of Philosophy of Psychedelics

In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of classic psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically (and perhaps, therefore, ethically) objectionable. In the book I develop a new response to this Objection which involves showing that a popular conception of psychedelics as agents of insight and spirituality is both consistent with a naturalistic worldview and plausible in light of current scientific knowledge. Exotic metaphysical ideas do sometimes come up, but they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics cause therapeutic benefits by altering the sense of self, and changing how people relate to their own minds and lives--not by changing their beliefs about the ultimate nature of reality. Thus, an "Entheogenic Conception" of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth--even if no Cosmic Consciousness or divine Reality exists.
