What people notice about [when they are on] LSD is either what's right or wrong with themselves or how freaky the world is.

What good is a theory of how the universe works if it’s a series of tensor equations that, even when understood, come nowhere tangential to experience? The only intellectual or noetic or spiritual path worth following is one that builds on personal experience

At still higher doses psilocybin triggers this activity in the language-forming capacity of the brain that manifests as song and vision. Psilocybin may have synergized the emergence of higher forms of psychic organization out of primitive protohuman animals. It can be seen as a kind of evolutionary enzyme, or evolutionary catalyst.

The world is mental in some way that we do not yet understand, but that which we're edging toward understanding. And the world is made of language. I can't say that enough. Whenever we get into these discussions about reality, or effects in space and time, we are operating outside this assumption that the world is made of language.

If you sit down with a person, or a watermelon for that matter, when you're stoned and sing into it, the quality of the hallucination is such that there is a way of thinking about it where you could say, 'This is an acoustical hologram of the interior of their body.'" I don't say that.I just say, "My goodness isn't it strange that I seem to be able to see inside of the watermelon when I'm doing this.'

I do not think that the government, under the guise of some phony, alarmist, pseudo-scientific rhetoric, should attempt to control the evolution of consciousness. After all, if these things truly are consciousness-expanding, it doesn't take too much intelligence to realize that it is the absence of consciousness that is causing our flirtation with extinction and planetary disaster.

It is curious that what these psychedelics do, on a scale of a community, is they release new ideas. . . . And that this is how culture moves forward. That culture is a phenomenon dependent on the generation of ideas, plans, notions, connections. So this is precisely what these compounds are doing.
