When I use the word ‘psychedelic’ I mean it as used in the term ‘psychedelic shamanism’, not as in the term ‘psychedelic sixties’.
Humphry Osmond first proposed the term ‘psychedelic’ in 1956 via correspondence with Aldous Huxley. They were after a word that described the the visionary, mystical and healing properties of these substances, and one that did not have a pathological inference (such as with the term psychotomimetic, meaning ‘psychosis mimicking’). Osmond came up with psychedelic as deriving from the Greek psyche, soul, and delos, visible or manifest. Hence meaning soul or mind manifesting.
