Point IV. On Perseverance
I. Notion of Perseverance. Perseverance is a moral virtue inclining man to persist in good works up to the limit prescribed by reason, notwithstanding the difficulty which arises from their duration. It is said: notwithstanding the difficulty which arises from their duration: by these words is indicated the matter of this virtue, as distinct from the matter of patience.
II. Object of Perseverance. 1. The remote material object is all good works insofar as they are lasting; but the proximate object is the difficulty which flows from duration.
- The remote formal object is the reason of debt by which we are not overcome by the difficulty of duration; but the proximate formal object is the special moral goodness shining forth in overcoming difficulty of this sort.
III. Opposed Vices. By defect there is opposed softness, by which someone, on account of the difficulty of the work's duration, withdraws from it against reason (St. Thomas, II-II, q. 138, a. 1); by excess, pertinacity, by which someone persists in a work undertaken, adhering to his own judgment against reason (St. Thomas, II-II, q. 138, a. 2).
