I think it's the sheer power of the hallucinogens that puts people off. You either love them or you hate them, and that's because they dissolve world views. And if you like the experience of having your entire ontological structure disappear out from under you, if you think that's a thrill, you'll probably love psychedelics.
Terence McKennaTime is a topological manifold. It is a surface. Events flow across it like water over land and like water flowing over land, when the land is flat, the water becomes reflective and moves slowly. When the landscape becomes disrupted, the water moves faster and chaotic attractors appear and new kinds of activity emerge and out of that new activity, there comes the new states that define the future.
Terence McKennaBecause the planetary culture is becoming ever more closely knitted together all its parts are becoming co-dependent.
Terence McKennaThis is a general law of the universe, overlooked by science, that out of complexity emerges greater complexity. We could almost say that the universe, nature, is a novelty-conserving, or complexity-conserving engine.
