Terence Kemp McKenna (November 16, 1946 – April 3, 2000) was an American ethnobotanist, mystic, psychonaut, lecturer, author, and an advocate for the responsible use of naturally occurring psychedelic plants. He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, environmentalism, and the theoretical origins of human consciousness. He was called the "Timothy Leary of the '90s", "one of the leading authorities on the ontological foundations of shamanism", and the "intellectual voice of rave culture".Read about Terence McKenna in Wikipedia
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.
. . . situations evolve as matter responds to the conditioning of time and space. . . If you know what is contained in time from its beginning to its end you are somehow no longer in time. Even though you still have a body and still eat and do what you do, you have discovered something that liberated you into a satisfying all-at-oneness.
