Of Ingratitude

Of Ingratitude — St. Thomas Aquinas asks: Whether ingratitude is always a sin?; Whether ingratitude is a special sin?; Whether ingratitude is always a mortal sin?; Whether favors should be withheld from the ungrateful?.

We must now consider ingratitude, under which head there are four points of inquiry:

Article 1: Whether ingratitude is always a sin?

Ingratitude is reckoned among other sins (2 Tim. 3:2), where it is written: "Disobedient to parents, ungrateful, wicked." etc.

As stated above (, ) a debt of gratitude is a moral debt required by virtue. Now a thing is a sin from the fact of its being contrary to virtue. Wherefore it is evident that every ingratitude is a sin.

Article 2: Whether ingratitude is a special sin?

Ingratitude is opposed to gratitude or thankfulness, which is a special virtue. Therefore it is a special sin.

Every vice is denominated from a deficiency of virtue, because deficiency is more opposed to virtue: thus illiberality is more opposed to liberality than prodigality is. Now a vice may be opposed to the virtue of gratitude by way of excess, for instance if one were to show gratitude for things for which gratitude is not due, or sooner than it is due, as stated above (). But still more opposed to gratitude is the vice denoting deficiency of gratitude, because the virtue of gratitude, as stated above (), inclines to return something more. Wherefore ingratitude is properly denominated from being a deficiency of gratitude. Now every deficiency or privation takes its species from the opposite habit: for blindness and deafness differ according to the difference of sight and hearing. Therefore just as gratitude or thankfulness is one special virtue, so also is ingratitude one special sin.

It has, however, various degrees corresponding in their order to the things required for gratitude. The first of these is to recognize the favor received, the second to express one's appreciation and thanks, and the third to repay the favor at a suitable place and time according to one's means. And since what is last in the order of generation is first in the order of destruction, it follows that the first degree of ingratitude is when a man fails to repay a favor, the second when he declines to notice or indicate that he has received a favor, while the third and supreme degree is when a man fails to recognize the reception of a favor, whether by forgetting it or in any other way. Moreover, since opposite affirmation includes negation, it follows that it belongs to the first degree of ingratitude to return evil for good, to the second to find fault with a favor received, and to the third to esteem kindness as though it were unkindness.

Article 3: Whether ingratitude is always a mortal sin?

As appears from what we have said above (), a man may be ungrateful in two ways: first, by mere omission, for instance by failing to recognize the favor received, or to express his appreciation of it or to pay something in return, and this is not always a mortal sin, because, as stated above (), the debt of gratitude requires a man to make a liberal return, which, however, he is not bound to do; wherefore if he fail to do so, he does not sin mortally. It is nevertheless a venial sin, because it arises either from some kind of negligence or from some disinclination to virtue in him. And yet ingratitude of this kind may happen to be a mortal sin, by reason either of inward contempt, or of the kind of thing withheld, this being needful to the benefactor, either simply, or in some case of necessity.

Secondly, a man may be ungrateful, because he not only omits to pay the debt of gratitude, but does the contrary. This again is sometimes mortal and sometimes a venial sin, according to the kind of thing that is done.

It must be observed, however, that when ingratitude arises from a mortal sin, it has the perfect character of ingratitude, and when it arises from venial sin, it has the imperfect character.

Article 4: Whether favors should be withheld from the ungrateful?

It is written (Lk. 6:35) that "the Highest . . . is kind to the unthankful, and to the evil." Now we should prove ourselves His children by imitating Him (Lk. 6:36). Therefore we should not withhold favors from the ungrateful.

There are two points to be considered with regard to an ungrateful person. The first is what he deserves to suffer and thus it is certain that he deserves to be deprived of our favor. The second is, what ought his benefactor to do? For in the first place he should not easily judge him to be ungrateful, since, as Seneca remarks (De Benef. iii), "a man is often grateful although he repays not," because perhaps he has not the means or the opportunity of repaying. Secondly, he should be inclined to turn his ungratefulness into gratitude, and if he does not achieve this by being kind to him once, he may by being so a second time. If, however, the more he repeats his favors, the more ungrateful and evil the other becomes, he should cease from bestowing his favors upon him.
