Oscar Ichazo (July 24, 1931 – March 26, 2020) was a Bolivian philosopher and an advocate of integral theory. Following his early life in Bolivia, Ichazo was later principally based in Chile, where he founded the Arica School in 1968. He lived his last decades in Hawaii, where he died. Ichazo's Arica School can be considered, as Ramparts magazine described it in 1973, "A body of techniques for cosmic consciousness-raising and an ideology to relate to the world in an awakened way." An American headquarters, the Arica Institute, was established in New York in 1971.
