The word âesotericâ derives from the Greek esoterikos, and is a comparative form of eso, meaning âwithin.â Its first known mention in Greek is in Lucianâs ascription to Aristotle of having âesotericâ [inner] and âexotericâ [outer] teachings. The word later came to designate the secret doctrines said to have been taught by Pythagoras to a select group of disciples, and, in general, to any teachings designed for or appropriate to an inner circle of disciples or initiates. In this sense, the word was brought into English in 1655 by Stanley in his History of Philosophy.
