 As this quotation shows, Augustine’s understanding of probability was thought to coincide with Aristotle’s, a fact that must have buttressed the endoxic notion of probability. Yet, while Augustine is not often referred to in medieval definitions of probability, a reference to Topics I became a commonplace. It seems immediately clear why an endoxic understanding of probabilis led to the modern translations “reputable”, “plausible”, “believable”, “approvable”, or “approved”. Reputability and approval, however, are not necessarily indicators of truth, and therefore the role that endoxa played for Aristotle and for the scholastics needs clarification.
