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

The main thing to understand is that we are imprisoned in some kind of work of art.

The psychedelics are this immense tool for the inspection of our own nature.

Science is the exploration of the experience of nature without psychedelics. And I propose, therefore, to expand that enterprise and say that we need a science beyond science. We need a science which plays with a full deck.

I'm not an advocate of drugs. I'm an advocate of psychedelics.

Shamanism, on the other hand, is this world wide, since Paleolithic-times, tradition which says that you must make your own experience the center piece of any model of the world that you build.

To my mind this is what shamanic training must really be, is mnemonic training. If you want to bring the stuff back you have to train yourself to bring it back.
