Jonathan Ott delivered a brilliant lecture on the history of “entheogens”—a term he helped coin. He traced their use all the way back to the Eleusinian mysteries of the Greeks, through the “pharmocratic inquisition,” when the Spanish conquest suppressed the Mesoamerican mushroom cults, and forward to the “entheogenic reformation” that has been under way since R. Gordon Wasson’s discovery that those cults had survived in Mexico.
