doxa

Doxa (δόξα) is a Greek word meaning common belief or popular opinion, from which are derived the modern terms of orthodoxy and heterodoxy. Used by the Greek rhetoricians as a tool for the formation of argument by using common opinions, the doxa was often manipulated by sophists to persuade the people, leading to Plato's condemnation of Athenian democracy.
