Ἐξ ὑποθέσεως

Aristotle says that some faculties¹ hypothetically follow the character-dispositions² which they would make use of if they were to come into being in that [situation] in respect of which the faculties are useful. For example, the faculty [which] hypothetically follows mildness, which is a character-disposition, [is] the ability to master an anger both immoderate and inappropriate, if ever it fell on [someone].³ So this faculty hypothetically follows mildness; for if someone were to get angry, he will master [the anger].
