(A. 10), anger is closely allied with fortitude. Now
anger is not accounted a principal passion; nor is daring which
belongs to fortitude. Therefore neither should fortitude be reckoned
a cardinal virtue.

Obj. 2: Further, the object of virtue is good. But the direct object
of fortitude is not good, but evil, for it is endurance of evil and
toil, as Tully says (De Invent. Rhet. ii). Therefore fortitude is not
a cardinal virtue.

Obj. 3: Further, the cardinal virtues are about those things upon
which human life is chiefly occupied, just as a door turns upon a
hinge (_cardine_). But fortitude is about dangers of death which are
of rare occurrence in human life. Therefore fortitude should not be
reckoned a cardinal or principal virtue.

_On the contrary,_ Gregory (Moral. xxii), Ambrose in his commentary
on Luke 6:20, and Augustine (De Moribus Eccl. xv), number fortitude
among the four cardinal or principal virtues.

_I answer that,_ As stated above (I-II, Q. 61, AA. 3, 4), those
virtues are said to be cardinal or principal which have a foremost
claim to that which belongs to the virtues in common. And among other
conditions of virtue in general one is that it is stated to "act
steadfastly," according to _Ethic._ ii, 4. Now fortitude above all
lays claim to praise for steadfastness. Because he that stands firm
is so much the more praised, as he is more strongly impelled to fall
or recede. Now man is impelled to recede from that which is in
accordance with reason, both by the pleasing good and the displeasing
evil. But bodily pain impels him more strongly than pleasure. For
Augustine says (QQ. 83, qu. 36): "There is none that does not shun
pain more than he desires pleasure. For we perceive that even the
most untamed beasts are deterred from the greatest pleasures by the
fear of pain." And among the pains of the mind and dangers those are
mostly feared which lead to death, and it is against them that the
brave man stands firm. Therefore fortitude is a cardinal virtue.

Reply Obj. 1: Daring and anger do not cooperate with fortitude in its
act of endurance, wherein its steadfastness is chiefly commended: for
it is by that act that the brave man curbs fear, which is a principal
passion, as stated above (I-II, Q. 25, A. 4).

Reply Obj. 2: Virtue is directed to the good of reason which it
behooves to safeguard against the onslaught of evils. And fortitude
is directed to evils of the body, as contraries which it withstands,
