Reply Obj. 3: Every virtue derives from its species a certain luster or adornment which is proper to each virtue: but further adornment results from the very greatness of a virtuous deed, through magnanimity which makes all virtues greater as stated in Ethic. iv, 3. _______________________
FIFTH ARTICLE [II-II, Q. 129, Art. 5]
Whether Magnanimity Is a Part of Fortitude?
Objection 1: It seems that magnanimity is not a part of fortitude. For a thing is not a part of itself. But magnanimity appears to be the same as fortitude. For Seneca says (De Quat. Virtut.): "If magnanimity, which is also called fortitude, be in thy soul, thou shalt live in great assurance": and Tully says (De Offic. i): "If a man is brave we expect him to be magnanimous, truth-loving, and far removed from deception." Therefore magnanimity is not a part of fortitude.
Obj. 2: Further, the Philosopher (Ethic. iv, 3) says that a magnanimous man is not philokindynos, that is, a lover of danger. But it belongs to a brave man to expose himself to danger. Therefore magnanimity has nothing in common with fortitude so as to be called a part thereof.
Obj. 3: Further, magnanimity regards the great in things to be hoped for, whereas fortitude regards the great in things to be feared or dared. But good is of more import than evil. Therefore magnanimity is a more important virtue than fortitude. Therefore it is not a part thereof.
On the contrary, Macrobius (De Somn. Scip. i) and Andronicus reckon magnanimity as a part of fortitude.
I answer that, As stated above (I-II, Q. 61, A. 3), a principal virtue is one to which it belongs to establish a general mode of virtue in a principal matter. Now one of the general modes of virtue is firmness of mind, because "a firm standing is necessary in every virtue," according to Ethic. ii. And this is chiefly commended in those virtues that tend to something difficult, in which it is most difficult to preserve firmness. Wherefore the more difficult it is to stand firm in some matter of difficulty, the more principal is the virtue which makes the mind firm in that matter.
Now it is more difficult to stand firm in dangers of death, wherein fortitude confirms the mind, than in hoping for or obtaining the greatest goods, wherein the mind is confirmed by magnanimity, for, as man loves his life above all things, so does he fly from dangers of death more than any others. Accordingly it is clear that magnanimity agrees with fortitude in confirming the mind about some difficult matter; but it falls short thereof, in that it confirms the mind about a matter wherein it is easier to stand firm. Hence magnanimity is reckoned a part of fortitude, because it is annexed thereto as secondary to principal.
Reply Obj. 1: As the Philosopher says (Ethic. v, 1, 3), "to lack evil is looked upon as a good," wherefore not to be overcome by a grievous evil, such as the danger of death, is looked upon as though it were the obtaining of a great good, the former belonging to fortitude, and the latter to magnanimity: in this sense fortitude and magnanimity may be considered as identical. Since, however, there is a difference as regards the difficulty on the part of either of the aforesaid, it follows that properly speaking magnanimity, according to the Philosopher (Ethic. ii, 7), is a distinct virtue from fortitude.
