Lambda Pi Eta is the official communication studies honor society of the National Communication Association (NCA). LPH was founded in 1985 at the University of Arkansas. LPH became a part of the NCA in 1988, and the official honor society of the NCA in July 1995. LPH represents what Aristotle described in his book, Rhetoric, as the three ingredients of persuasion: Logos (Lambda) meaning logic, Pathos (Pi) relating to emotion, and Ethos (Eta) defined as character credibility and ethics.
