Epistemological psychology
The term episteme is related to the Greek word επιστήμη, which translates literally as "standing near or by that which causes" but is often simplified as "knowledge" or "science". By ignoring ego interests the core impetus or the essence of a deed, real or imagined, is recovered.
Epicenter
The word is derived from the New Latin noun "epicentrum", the latinisation of the ancient Greek adjective ἐπίκεντρος ("epikentros"), "occupying a cardinal point, situated on a centre", from ἐπί ("epi") "on, upon, at" and κέντρον ("kentron") "centre". The term was coined by the Irish seismologist Robert Mallet.
