Whether perseverance is a virtue?

❌ Objection 1 : It seems that perseverance is not a virtue. For, according to the Philosopher (Ethic. vii, 7), continency is greater than perseverance. But continency is not a virtue, as stated in Ethic. iv, 9. Therefore perseverance is not a virtue.

❌ Objection 2 : Further, "by virtue man lives aright," according to Augustine (De Lib. Arb. ii, 19). Now according to the same authority (De Persever. i), no one can be said to have perseverance while living, unless he persevere until death. Therefore perseverance is not a virtue.

❌ Objection 3 : Further, it is requisite of every virtue that one should persist unchangeably in the work of that virtue, as stated in Ethic. ii, 4. But this is what we understand by perseverance: for Tully says (De Invent. Rhet. ii) that "perseverance is the fixed and continued persistence in a well-considered purpose." Therefore perseverance is not a special virtue, but a condition of every virtue.
