Terence McKenna on the I Ching

Terence McKenna was an American ethnobotanist, mystic, psychonaut, lecturer, and author who spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, and the theoretical origins of human consciousness. McKenna formulated a concept about the nature of time based on fractal patterns he claimed to have discovered in the I Ching, which he called novelty theory.
