Whether the brave man acts for the sake of the good of his habit?

Objections

Objection 1 : It seems that the brave man does not act for the sake of the good of his habit. For in matters of action the end, though first in intention, is last in execution. Now the act of fortitude, in the order of execution, follows the habit of fortitude. Therefore it is impossible for the brave man to act for the sake of the good of his habit.
Objection 2 : Further, Augustine says (De Trin. xiii): "We love virtues for the sake of happiness, and yet some make bold to counsel us to be virtuous," namely by saying that we should desire virtue for its own sake, "without loving happiness. If they succeed in their endeavor, we shall surely cease to love virtue itself, since we shall no longer love that for the sake of which alone we love virtue." But fortitude is a virtue. Therefore the act of fortitude is directed not to fortitude but to happiness.
Objection 3 : Further, Augustine says (De Morib. Eccl. xv) that "fortitude is love ready to bear all things for God's sake." Now God is not the habit of fortitude, but something better, since the end must needs be better than what is directed to the end. Therefore the brave man does not act for the sake of the good of his habit.
