Whether the intellect can be the subject of virtue?

Objections

Objection 1 : It would seem that the intellect is not the subject of virtue. For Augustine says (De Moribus Eccl. xv) that all virtue is love. But the subject of love is not the intellect, but the appetitive power alone. Therefore no virtue is in the intellect.
Objection 2 : Further, virtue is referred to good, as is clear from what has been said above (Question [55], Article [3]). Now good is not the object of the intellect, but of the appetitive power. Therefore the subject of virtue is not the intellect, but the appetitive power.
Objection 3 : Further, virtue is that "which makes its possessor good," as the Philosopher says (Ethic. ii, 6). But the habit which perfects the intellect does not make its possessor good: since a man is not said to be a good man on account of his science or his art. Therefore the intellect is not the subject of virtue.
