It is our actions and the soul's active exercise of its functions that we posit (as being Happiness).
AristotleA state of the soul is either (1) an emotion, (2) a capacity, or (3) a disposition; virtue therefore must be one of these three things.
Aristotle[Prudence] is the virtue of that part of the intellect [the calculative] to which it belongs; and . . . our choice of actions will not be right without Prudence any more than without Moral Virtue, since, while Moral Virtue enables us to achieve the end, Prudence makes us adopt the right means to the end.
Aristotle
