Doxa, A Philosopheme
Plato tended to oppose knowledge to doxa, which led to the classical opposition of error to truth, which has since become a major concern in Western philosophy. (However, in the Theaetetus and in the Meno, Plato has Socrates suggest that knowledge is orthos doxa for which one can provide a logos, thus initiating the traditional definition of knowledge as "justified true belief".) Thus, error is considered in Occident as pure negativity, which can take various forms, among them the form of illusion. As such, doxa may ironically be defined as the "philosopher's sin". In classical rhetoric, it is contrasted with episteme. However, Aristotle used the term endoxa (commonly held beliefs accepted by the wise and by elder rhetors) to acknowledge the beliefs of the city. Endoxa is a more stable belief than doxa, because it has been "tested" in argumentative struggles in the Polis by prior interlocutors. The use of endoxa in the Stagirite's Organon can be found in Aristotle's Topics and Rhetoric.
