Portrait of Thomas Aquinas Thomas Aquinas Summa Theologiae — Question 123 - OF FORTITUDE…

It seems that endurance is not the chief act of fortitude. For virtue "is about the difficult and the good" (Ethic. ii, 3) . Now it is more difficult to attack than to endure. Therefore endurance is not the chief act of fortitude.
Objection 2: Further, to be able to act on another seems to argue greater power than not to be changed by another. Now to attack is to act on another, and to endure is to persevere unchangeably. Since then fortitude denotes perfection of power, it seems that it belongs to fortitude to attack rather than to endure.
