Whether perseverance is a part of fortitude?

❌ Objection 1 : It seems that perseverance is not a part of fortitude. For, according to the Philosopher (Ethic. viii, 7), "perseverance is about pains of touch." But these belong to temperance. Therefore perseverance is a part of temperance rather than of fortitude.

❌ Objection 2 : Further, every part of a moral virtue is about certain passions which that virtue moderates. Now perseverance does not imply moderation of the passions: since the more violent the passions, the more praiseworthy is it to persevere in accordance with reason. Therefore it seems that perseverance is a part not of a moral virtue, but rather of prudence which perfects the reason.

❌ Objection 3 : Further, Augustine says (De Persev. i) that no one can lose perseverance; whereas one can lose the other virtues. Therefore perseverance is greater than all the other virtues. Now a principal virtue is greater than its part. Therefore perseverance is not a part of a virtue, but is itself a principal virtue.
