One way to think about what psychedelics are is as catalysts for language development. They literally force the evolution of language. You cannot evolve faster than your language because the language defines the culture of meaning. So if there's a way to accelerate the evolution of language then this is real consciousness expansion and it's a permanent thing. The great legacies of the 60's are in attitudes and language. It boils down to doing your own thing, feeling the vibe, ego-trip, blowing your mind.
Terence McKennaThe Truth doesn't need your cooperation to exist. All forms of cult, all forms of hype, all forms of delusion do require your participation in order to exist. I've looked into marginal areas of human experience -historical and otherwise- with a rational mind, and what I've found is that doorways into the miraculous are far fewer than the publicists of the New Age would have us believe. On the other hand, they are not as rare as the proponents of radical reductionism and materialism would have us believe. There are doorways out of the mundane.
Terence McKennaI finally realized that this 'place' that I kept bursting into [on a psychedelic experience] was somebody's idea of a playpen.
Terence McKennaApparently there is a great discovery or insight which our culture is deliberately designed to suppress, distort, and ignore. That is that nature is some kind of minded entity. That nature is not simply the random flight of atoms through electromagnetic fields. Nature is not the empty, despiritualized , lumpen matter that we inherit from modern physics. But it is instead a kind of intelligence, a kind of mind.
