 For Cicero, probability represents the usual course of events, commonly held beliefs, or what resembles them. His characterization of probability thus contains the roots of at least two different concepts of probability. Boethius repeats Aristotle’s definition of an endoxon (see Section 3.1) as a readily believable proposition almost verbatim and calls it probabilis. In this respect, he prepared the way for the reception of Aristotle’s original definition; but note that Boethius addresses the role of experts more explicitly than Aristotle, who in medieval translations summarily refers to sapientes, the  wise.[11]
