But a mature humanity could get into a place where we no longer required these metaphysical spankings from messiahs and flying saucers that come along every thousand years or so to mess up the mess that has been created and try and send people off on another tack. And the way to do this is to look at the abysses that confront man as species and individuals and try to unify them. And I think that psilocybin offers a way out because it allows a dialogue with the over-mind. You won't read about it in "Scientific American" or anywhere else. You will carry it out.

One of the things that's so striking about shamanism in the native context is the absence of mental illness.

I often like to think that our map of the world is wrong, that where we have centered physics, we should actually place literature as the central metaphor that we want to work out from. Because I think literature occupies the same relationship to life that life occupies to death. A book is life with one dimension pulled out of it. And life is something that lacks a dimension which death will give it. I imagine death to be a kind of release into the imagination in the sense that for characters in a book, what we experience is an unimaginable dimension of freedom.

Who is to say what is real and what is not?'Real' is a distinction of a naïve mind.

A birth is a death. Everything you treasure, and believe in, and love, and relate to is destroyed for you when you leave the womb. And you are launched into another modality, a modality that perhaps you would not have chosen but that you cannot do anything about.

This is what they have suppressed so long. This is why they are so afraid of the psychedelics, because they understand that once you touch the inner core of your own and someone else's being you can't be led into thing-fetishes and consumerism. The message of psychedelics is that culture can be re-engineered as a set of emotional values rather than products. This is terrifying news.

Our assumptions are the edges of our worlds.
