Of Perseverance

Of Perseverance — St. Thomas Aquinas asks: Whether perseverance is a virtue?; Whether perseverance is a part of fortitude?; Whether constancy pertains to perseverance?; Whether perseverance needs the help of grace?.

We must now consider perseverance and the vices opposed to it. Under the head of perseverance there are four points of inquiry:

Article 1: Whether perseverance is a virtue?

Andronicus [*Chrysippus: in De Affect.] says that "perseverance is a habit regarding things to which we ought to stand, and those to which we ought not to stand, as well as those that are indifferent." Now a habit that directs us to do something well, or to omit something, is a virtue. Therefore perseverance is a virtue.

According to the Philosopher (Ethic. ii, 3), "virtue is about the difficult and the good"; and so where there is a special kind of difficulty or goodness, there is a special virtue. Now a virtuous deed may involve goodness or difficulty on two counts. First, from the act's very species, which is considered in respect of the proper object of that act: secondly, from the length of time, since to persist long in something difficult involves a special difficulty. Hence to persist long in something good until it is accomplished belongs to a special virtue.

Accordingly just as temperance and fortitude are special virtues, for the reason that the one moderates pleasures of touch (which is of itself a difficult thing), while the other moderates fear and daring in connection with dangers of death (which also is something difficult in itself), so perseverance is a special virtue, since it consists in enduring delays in the above or other virtuous deeds, so far as necessity requires.

Article 2: Whether perseverance is a part of fortitude?

Tully (De Invent. Rhet. ii) reckons perseverance as a part of fortitude.

As stated above (; ), a principal virtue is one to which is principally ascribed something that lays claim to the praise of virtue, inasmuch as it practices it in connection with its own matter, wherein it is most difficult of accomplishment. In accordance with this it has been stated () that fortitude is a principal virtue, because it observes firmness in matters wherein it is most difficult to stand firm, namely in dangers of death. Wherefore it follows of necessity that every virtue which has a title to praise for the firm endurance of something difficult must be annexed to fortitude as secondary to principal virtue. Now the endurance of difficulty arising from delay in accomplishing a good work gives perseverance its claim to praise: nor is this so difficult as to endure dangers of death. Therefore perseverance is annexed to fortitude, as secondary to principal virtue.

Article 3: Whether constancy pertains to perseverance?

One is said to be constant because one stands to a thing. Now it belongs to perseverance to stand to certain things, as appears from the definition given by Andronicus. Therefore constancy belongs to perseverance.

Perseverance and constancy agree as to end, since it belongs to both to persist firmly in some good: but they differ as to those things which make it difficult to persist in good. Because the virtue of perseverance properly makes man persist firmly in good, against the difficulty that arises from the very continuance of the act: whereas constancy makes him persist firmly in good against difficulties arising from any other external hindrances. Hence perseverance takes precedence of constancy as a part of fortitude, because the difficulty arising from continuance of action is more intrinsic to the act of virtue than that which arises from external obstacles.

Article 4: Whether perseverance needs the help of grace?

Augustine says (De Persev. i): "We hold that perseverance is a gift of God, whereby we persevere unto the end, in Christ."

As stated above (; ), perseverance has a twofold signification. First, it denotes the habit of perseverance, considered as a virtue. In this way it needs the gift of habitual grace, even as the other infused virtues. Secondly, it may be taken to denote the act of perseverance enduring until death: and in this sense it needs not only habitual grace, but also the gratuitous help of God sustaining man in good until the end of life, as stated above (), when we were treating of grace. Because, since the free-will is changeable by its very nature, which changeableness is not taken away from it by the habitual grace bestowed in the present life, it is not in the power of the free-will, albeit repaired by grace, to abide unchangeably in good, though it is in its power to choose this: for it is often in our power to choose yet not to accomplish.
