The entry for probable is, “‘Probable’ is used in two ways. First as the opposite of hidden, that is what is proved by witnesses (see ‘Notorious’). Second, as what pertains to opinion. And this in two ways. First, the object of a believed opinion; thus Aristotle (Topics I) says that the probable is what seems to be to all, or most, or the wise . . . according to the Chancellor [Gerson], what is thus probable is called morally certain . . . it is equally vicious for the mathematician to seek the persuasive as for the moralist the demonstrative.”
