Flow

The Beliefs of a Witoto shaman and the beliefs of a Princeton phenomenologist have an equal chance of being correct, and there are no arbiters of who is right. Here is something we have not assimilated. We have been to the moon, we have charted the depths of the ocean and the heart of the atom, but we have a fear of looking inward to ourselves because we sense that is where all the contradictions flow together.
--Terence McKenna, "The Archaic Revival" (1991)
