Disputation II: On the Virtues Joined to Fortitude

Fortitude indeed has no subjective parts, of which it might be predicated as a genus; for it is not divided into many virtues specifically distinct; it is one special virtue about a specific object; it has, however, integral parts according to those things which must concur for the act of fortitude; it has also potential parts, inasmuch as those things which fortitude observes about the most difficult matters, namely, the dangers of death, certain other virtues observe about certain other less arduous things, and these are joined to fortitude.

The integral parts of Fortitude, moreover, are four: Magnanimity, or confidence, and a certain hope implanted by virtue of surely overcoming the dangers of death. Magnificence, insofar as it signifies the constant execution of those things which one has destined in his mind by prior confidence. Patience, by which the mind is not broken by sorrow under the difficulty of imminent dangers of death. Perseverance, signifying a mind unmoved amid the dangers of death, and enduring in good even to the end. So S. Thomas loc. cit. ex Tullio lib. 2. de Invent.
