Psychedelic historian Tom Hatsis was an atheist until he tried psychedelics. Then he went from atheist to theist. Psychedelic encounters reshaped his understanding of the divine.

In our conversation, Hatsis and I dove into the enigmatic world of psychedelics, exploring their history, safety, and transformative potential. Hatsis, a meticulous researcher, unpacked the distinctions between DMT, Ayahuasca, psilocybin mushrooms, and 5-MeO-DMT, each offering unique pathways to altered states of consciousness.

Jacob countered, emphasizing its moral weight as a cornerstone of human dignity. I don’t disagree, but I believe the moral framing is too abstract for broad appeal.

My guest for this episode was Jamie Roberts, author of the excellent Intellectual Dark Web: A History (and Possible Future). We traced the IDW’s rise, fragmentation, and legacy.
