Terence McKenna

Terence McKenna (1946—2000) was an American philosopher, psychonaut, and writer. He is known for his research on the use of psychoactive substances, particularly psychedelics, and their effects on human consciousness. McKenna was a proponent of the importance of shamanism and the study of altered states of consciousness, and his ideas have had a significant influence on the field of psychedelic research. He wrote and lectured extensively on a wide range of topics, including language, culture, spirituality, and the future of humanity.

McKenna is perhaps best known for his “Stoned Ape” theory of human evolution, his development of Novelty Theory and the Timewave Zero concept, and his passionate advocacy for the responsible exploration of psychedelic states as tools for understanding the nature of mind and reality. His spoken-word recordings continue to circulate widely, admired for their eloquence, humor, and intellectual range.
