Epistemology
The word "epistemology" is derived from the ancient Greek "epistēmē" meaning "knowledge" and the suffix "-logy", meaning "logical discourse" (derived from the Greek word "logos" meaning "discourse"). It is analogue to the German "Wissenschaftslehre" (literally, theory of science) which was introduced by philosophers Johann Fichte and Bernard Bolzano in the late 18th century. The word first appeared in English in 1847 as a translation of the German in New York's "Eclectic Magazine" review of a philosophical novel by German author Jean Paul:
Humphry Osmond
Humphry Osmond first proposed the term "psychedelic" at a meeting of the New York Academy of Sciences in 1956. He said the word meant "mind manifesting" (from "mind", ψυχή (psyche), and "manifest", δήλος (delos)) and called it "clear, euphonious and uncontaminated by other associations." Huxley had sent Osmond a rhyme containing his own suggested invented word: ""To make this trivial world sublime, take half a gram of phanerothyme"" (θυμός (thymos) meaning 'spiritedness' in Ancient Greek.) Osmond countered with ""To fathom Hell or soar angelic, just take a pinch of psychedelic"" (Alternative version: "To fall in Hell or soar angelic / You'll need a pinch of psychedelic.").
