Safety is really a concern of mine, and what I've been telling people recently is that until there's animal and human data on a drug it should probably be looked at very carefully.

The numinous depth of the mystery that seems to have called us out of the animal mind is completely impenetrable to modern analysis.

All the accoutrements that distinguish us from animal existence were put in place when we had a different kind of mind than we have now. We didn't have a mind that favored role specialization, and male dominance, and anxiety over female sexual activity related to feelings of male ownership. That all came later.

To me it begins and ends with these psychedelic substances. The synergy of the psilocybin in the hominid diet brought us out of the animal mind and into the world of articulated speech and imagination.
