The story of the word

The psychiatrist Humphry Osmond coined it in a verse exchange with Aldous Huxley in 1956. Huxley had proposed phanerothyme, spirit-made-visible; Osmond replied with a couplet about fathoming hell or soaring angelic on a pinch of psychedelic, and published the word in 1957. He wanted a term free of the pathology built into hallucinogen, since the drugs showed the mind rather than deceived it.
