Whether any other virtues should be called principal rather than these?

Objections

Objection 1 : It would seem that other virtues should be called principal rather than these. For, seemingly, the greatest is the principal in any genus. Now "magnanimity has a great influence on all the virtues" (Ethic. iv, 3). Therefore magnanimity should more than any be called a principal virtue.
Objection 2 : Further, that which strengthens the other virtues should above all be called a principal virtue. But such is humility: for Gregory says (Hom. iv in Ev.) that "he who gathers the other virtues without humility is as one who carries straw against the wind." Therefore humility seems above all to be a principal virtue.
Objection 3 : Further, that which is most perfect seems to be principal. But this applies to patience, according to James 1:4: "Patience hath a perfect work." Therefore patience should be reckoned a principal virtue.
