The Transformations Of Language Under The Influence Of The Psychedelic Experience:
Berkley, CA (October 1983)
"I think the gradual evolution of language is actually the gradual lifting of the veil that is imposed between ourselves and meaning by the planetary ecology. In other words, the forward thrust of history is actually regulated by the ecology, and it is regulated through control of the evolution of language. Because what you cannot think you cannot do, and where you cannot imagine you cannot steer your culture and go. So I'm proposing on one level that hallucinogens be thought of as social pheromones that regulate the rate at which language develops and therefore regulates the evolution of human culture generally."
