Psychedelics are illegal not because a loving government is concerned that you may jump out of a third story window. Psychedelics are illegal because they dissolve opinion structures and culturally laid down models of behaviour and information processing. They open you up to the possibility that everything you know is wrong.
Terence McKennaWhat is happening, I think, it's really bigger than psychedelics, it's bigger than human evolution. We are not making the waves in this ocean. We are corks, riding the waves of the ocean. But we are privileged, by perhaps chance alone, to occupy a unique moment in the history of the universe. A moment when the universe goes through some kind of self-transforming, evolutionary, inflationary expansion. That's what's happening.
