[prudence] Is The Virtue Of That Part Of The Intellect [the Calculative] To Which It Belongs; And . . .

The Vices Respectively Fall Short Of Or Exceed What Is Right In Both Passions And Actions, While Virtue Both Finds And Chooses That Which Is Intermediate.

The True Nature Of Anything Is What It Becomes At Its Highest.

Happiness, Then, Is Found To Be Something Perfect And Self-sufficient, Being The End To Which Our Actions Are Directed.

The Moral Virtues, Then, Are Produced In Us Neither By Nature Nor Against Nature. Nature, Indeed, Prepares In Us The Ground For Their Reception, But Their Complete Formation Is The Product Of Habit.
