Q: Whether the Repayment of Gratitude Should Surpass the Favor Received?

A: On the contrary,
The Philosopher says (Ethic. v, 5): "We should repay those who are gracious to us, by being gracious to them return," and this is done by repaying more than we have received. Therefore gratitude should incline to do something greater.

I answer that,
As stated above (A. 5), gratitude regards the favor received according the intention of the benefactor; who seems be deserving of praise, chiefly for having conferred the favor gratis without being bound to do so. Wherefore the beneficiary is under a moral obligation to bestow something gratis in return. Now he does not seem to bestow something gratis, unless he exceeds the quantity of the favor received: because so long as he repays less or an equivalent, he would seem to do nothing gratis, but only to return what he has received. Therefore gratitude always inclines, as far as possible, to pay back something more.

Reply Obj. 1: As stated above (A. 3, ad 5; A. 5), in repaying favors we must consider the disposition rather than the deed. Accordingly, if we consider the effect of beneficence, which a son receives from his parents namely, to be and to live, the son cannot make an equal repayment, as the Philosopher states (Ethic. viii, 14). But if we consider the will of the giver and of the repayer, then it is possible for the son to pay back something greater to his father, as Seneca declares (De Benef. iii). If, however, he were unable to do so, the will to pay back would be sufficient for gratitude.

Reply Obj. 2: The debt of gratitude flows from charity, which the more it is paid the more it is due, according to Rom. 13:8, "Owe no man anything, but to love one another." Wherefore it is not unreasonable if the obligation of gratitude has no limit.

Reply Obj. 3: As in injustice, which is a cardinal virtue, we consider equality of things, so in gratitude we consider equality of wills. For while on the one hand the benefactor of his own free-will gave something he was not bound to give, so on the other hand the beneficiary repays something over and above what he has received.

QUESTION 107

OF INGRATITUDE (In Four Articles)

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

(1) Whether ingratitude is always a sin?

(2) Whether ingratitude is a special sin?

(3) Whether every act of ingratitude is a mortal sin?

(4) Whether favors should be withdrawn from the ungrateful?
Q: Objection 1: It seems that there is no need for the repayment of gratitude to surpass the favor received. For it is not possible to make even equal repayment to some, for instance, one's parents, as the Philosopher states (Ethic. viii, 14). Now virtue does not attempt the impossible. Therefore gratitude for a favor does not tend to something yet greater.

Obj. 2: Further, if one person repays another more than he has received by his favor, by that very fact he gives him something his turn, as it were. But the latter owes him repayment for the favor which in his turn the former has conferred on him. Therefore he that first conferred a favor will be bound to a yet greater repayment, and so on indefinitely. Now virtue does not strive at the indefinite, since "the indefinite removes the nature of good" (Metaph. ii, text. 8). Therefore repayment of gratitude should not surpass the favor received.

Obj. 3: Further, justice consists in equality. But "more" is excess of equality. Since therefore excess is sinful in every virtue, it seems that to repay more than the favor received is sinful and opposed to justice.
Q: Whether Ingratitude Is Always a Sin?

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

I answer that,
As stated above (Q. 106, A. 4, ad 1, A. 6) 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.

Reply Obj. 1: Gratitude regards a favor received: and he that helps another to commit a sin does him not a favor but an injury: and so no thanks are due to him, except perhaps on account of his good will, supposing him to have been deceived, and to have thought to help him in doing good, whereas he helped him to sin. In such a case the repayment due to him is not that he should be helped to commit a sin, because this would be repaying not good but evil, and this is contrary to gratitude.

Reply Obj. 2: No man is excused from ingratitude through inability to repay, for the very reason that the mere will suffices for the repayment of the debt of gratitude, as stated above (Q. 106, A. 6, ad 1).

Forgetfulness of a favor received amounts to ingratitude, not indeed the forgetfulness that arises from a natural defect, that is not subject to the will, but that which arises from negligence. For, as Seneca observes (De Benef. iii), "when forgetfulness of favors lays hold of a man, he has apparently given little thought to their repayment."

Reply Obj. 3: The debt of gratitude flows from the debt of love, and from the latter no man should wish to be free. Hence that anyone should owe this debt unwillingly seems to arise from lack of love for his benefactor.
Q: Objection 1: It seems that ingratitude is not always a sin. For Seneca says (De Benef. iii) that "he who does not repay a favor is ungrateful." But sometimes it is impossible to repay a favor without sinning, for instance if one man has helped another to commit a sin. Therefore, since it is not a sin to refrain from sinning, it seems that ingratitude is not always a sin.

Obj. 2: Further, every sin is in the power of the person who commits it: because, according to Augustine (De Lib. Arb. iii; Retract. i), "no man sins in what he cannot avoid." Now sometimes it is not in the power of the sinner to avoid ingratitude, for instance when he has not the means of repaying. Again forgetfulness is not in our power, and yet Seneca declares (De Benef. iii) that "to forget a kindness is the height of ingratitude." Therefore ingratitude is not always a sin.

Obj. 3: Further, there would seem to be no repayment in being unwilling to owe anything, according to the Apostle (Rom. 13:8), "Owe no man anything." Yet "an unwilling debtor is ungrateful," as Seneca declares (De Benef. iv). Therefore ingratitude is not always a sin.
Q: Whether Ingratitude Is a Special Sin?

A: On the contrary,
Ingratitude is opposed to gratitude or thankfulness, which is a special virtue. Therefore it is a special sin.

I answer that,
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 (Q. 106, A. 4). But still more opposed to gratitude is the vice denoting deficiency of gratitude, because the virtue of gratitude, as stated above (Q. 106, A. 6), 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.

Reply Obj. 1: In every sin there is material ingratitude to God, inasmuch as a man does something that may pertain to ingratitude. But formal ingratitude is when a favor is actually contemned, and this is a special sin.

Reply Obj. 2: Nothing hinders the formal aspect of some special sin from being found materially in several kinds of sin, and in this way the aspect of ingratitude is to be found in many kinds of sin.

Reply Obj. 3: These three are not different species but different degrees of one special sin.
Q: Objection 1: It seems that ingratitude is not a special sin. For whoever sins acts against God his sovereign benefactor. But this pertains to ingratitude. Therefore ingratitude is not a special sin.

Obj. 2: Further, no special sin is contained under different kinds of sin. But one can be ungrateful by committing different kinds of sin, for instance by calumny, theft, or something similar committed against a benefactor. Therefore ingratitude is not a special sin.

Obj. 3: Further, Seneca writes (De Benef. iii): "It is ungrateful to take no notice of a kindness, it is ungrateful not to repay one, but it is the height of ingratitude to forget it." Now these do not seem to belong to the same species of sin. Therefore ingratitude is not a special sin.
Q: Whether Ingratitude Is Always a Mortal Sin?

A: I answer that,
As appears from what we have said above (A. 2), 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 (Q. 106, A. 6), 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 a 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.

Reply Obj. 1: By committing a venial sin one is not ungrateful to God to the extent of incurring the guilt of perfect ingratitude: but there is something of ingratitude in a venial sin, in so far as it removes a virtuous act of obedience to God.

Reply Obj. 2: When ingratitude is a venial sin it is not contrary to, but beside charity: since it does not destroy the habit of charity, but excludes some act thereof.

Reply Obj. 3: Seneca also says (De Benef. vii): "When we say that a man after conferring a favor should forget about it, it is a mistake to suppose that we mean him to shake off the recollection of a thing so very praiseworthy. When we say: He must not remember it, we mean that he must not publish it abroad and boast about it."

Reply Obj. 4: He that is unaware of a favor conferred on him is not ungrateful, if he fails to repay it, provided he be prepared to do so if he knew. It is nevertheless commendable at times that the object of a favor should remain in ignorance of it, both in order to avoid vainglory, as when Blessed Nicolas threw gold into a house secretly, wishing to avoid popularity: and because the kindness is all the greater through the benefactor wishing not to shame the person on whom he is conferring the favor.
Q: Objection 1: It seems that ingratitude is always a mortal sin. For one ought to be grateful to God above all. But one is not ungrateful to God by committing a venial sin: else every man would be guilty of ingratitude. Therefore no ingratitude is a venial sin.

Obj. 2: Further, a sin is mortal through being contrary to charity, as stated above (Q. 24, A. 12). But ingratitude is contrary to charity, since the debt of gratitude proceeds from that virtue, as stated above (Q. 106, A. 1, ad 3; A. 6, ad 2). Therefore ingratitude is always a mortal sin.

Obj. 3: Further, Seneca says (De Benef. ii): "Between the giver and the receiver of a favor there is this law, that the former should forthwith forget having given, and the latter should never forget having received." Now, seemingly, the reason why the giver should forget is that he may be unaware of the sin of the recipient, should the latter prove ungrateful; and there would be no necessity for that if ingratitude were a slight sin. Therefore ingratitude is always a mortal sin.

Obj. 4:
On the contrary,
No one should be put in the way of committing a mortal sin. Yet, according to Seneca (De Benef. ii), "sometimes it is necessary to deceive the person who receives assistance, in order that he may receive without knowing from whom he has received." But this would seem to put the recipient in the way of ingratitude. Therefore ingratitude is not always a mortal sin.
Q: Whether Favors Should Be Withheld from the Ungrateful?

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

I answer that,
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.

Reply Obj. 1: The passage quoted speaks of what the ungrateful man deserves to suffer.

Reply Obj. 2: He that bestows a favor on an ungrateful person affords him an occasion not of sin but of gratitude and love. And if the recipient takes therefrom an occasion of ingratitude, this is not to be imputed to the bestower.

Reply Obj. 3: He that bestows a favor must not at once act the part of a punisher of ingratitude, but rather that of a kindly physician, by healing the ingratitude with repeated favors.

QUESTION 108

OF VENGEANCE (In Four Articles)

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

(1) Whether vengeance is lawful?

(2) Whether it is a special virtue?

(3) Of the manner of taking vengeance;

(4) On whom should vengeance be taken?
Q: Objection 1: It seems that favors should withheld from the ungrateful. For it is written (Wis. 16:29): "The hope of the unthankful shall melt away as the winter's ice." But this hope would not melt away unless favors were withheld from him. Therefore favors should be withheld from the ungrateful.

Obj. 2: Further, no one should afford another an occasion of committing sin. But the ungrateful in receiving a favor is given an occasion of ingratitude. Therefore favors should not be bestowed on the ungrateful.

Obj. 3: Further, "By what things a man sinneth, by the same also he is tormented" (Wis. 11:17). Now he that is ungrateful when he receives a favor sins against the favor. Therefore he should be deprived of the favor.
Q: Objection 1: It seems that vengeance is not lawful. For whoever usurps what is God's sins. But vengeance belongs to God, for it is written (Deut. 32:35, Rom. 12:19): "Revenge to Me, and I will repay." Therefore all vengeance is unlawful.

Obj. 2: Further, he that takes vengeance on a man does not bear with him. But we ought to bear with the wicked, for a gloss on Cant. 2:2, "As the lily among the thorns," says: "He is not a good man that cannot bear with a wicked one." Therefore we should not take vengeance on the wicked.

Obj. 3: Further, vengeance is taken by inflicting punishment, which is the cause of servile fear. But the New Law is not a law of fear, but of love, as Augustine states (Contra Adamant. xvii). Therefore at least in the New Testament all vengeance is unlawful.

Obj. 4: Further, a man is said to avenge himself when he takes revenge for wrongs inflicted on himself. But, seemingly, it is unlawful even for a judge to punish those who have wronged him: for Chrysostom [*Cf. Opus Imperfectum, Hom. v in Matth., falsely ascribed to St. Chrysostom] says: "Let us learn after Christ's example to bear our own wrongs with magnanimity, yet not to suffer God's wrongs, not even by listening to them." Therefore vengeance seems to be unlawful.

Obj. 5: Further, the sin of a multitude is more harmful than the sin of only one: for it is written (Ecclus. 26:5-7): "Of three things my heart hath been afraid . . . the accusation of a city, and the gathering together of the people, and a false calumny." But vengeance should not be taken on the sin of a multitude, for a gloss on Matt. 13:29, 30, "Lest perhaps . . . you root up the wheat . . . suffer both to grow," says that "a multitude should not be excommunicated, nor should the sovereign." Neither therefore is any other vengeance lawful.
Q: Whether Vengeance Is a Special Virtue?

A: On the contrary,
Tully (De Invent. Rhet. ii) reckons it a part of justice.

I answer that,
As the Philosopher states (Ethic. ii, 1), aptitude to virtue is in us by nature, but the complement of virtue is in us through habituation or some other cause. Hence it is evident that virtues perfect us so that we follow in due manner our natural inclinations, which belong to the natural right. Wherefore to every definite natural inclination there corresponds a special virtue. Now there is a special inclination of nature to remove harm, for which reason animals have the irascible power distinct from the concupiscible. Man resists harm by defending himself against wrongs, lest they be inflicted on him, or he avenges those which have already been inflicted on him, with the intention, not of harming, but of removing the harm done. And this belongs to vengeance, for Tully says (De Invent. Rhet. ii) that by "vengeance we resist force, or wrong, and in general whatever is obscure" [*
Obscurum.
Cicero wrote
obfuturum
but the sense is the same as St. Thomas gives in the parenthesis] "(i.e. derogatory), either by self-defense or by avenging it." Therefore vengeance is a special virtue.

Reply Obj. 1: Just as repayment of a legal debt belongs to commutative justice, and as repayment of a moral debt, arising from the bestowal of a particular favor, belongs to the virtue of gratitude, so too the punishment of sins, so far as it is the concern of public justice, is an act of commutative justice; while so far as it is concerned in defending the rights of the individual by whom a wrong is resisted, it belongs to the virtue of revenge.

Reply Obj. 2: Fortitude disposes to vengeance by removing an obstacle thereto, namely, fear of an imminent danger. Zeal, as denoting the fervor of love, signifies the primary root of vengeance, in so far as a man avenges the wrong done to God and his neighbor, because charity makes him regard them as his own. Now every act of virtue proceeds from charity as its root, since, according to Gregory (Hom. xxvii in Ev.), "there are no green leaves on the bough of good works, unless charity be the root."

Reply Obj. 3: Two vices are opposed to vengeance: one by way of excess, namely, the sin of cruelty or brutality, which exceeds the measure in punishing: while the other is a vice by way of deficiency and consists in being remiss in punishing, wherefore it is written (Prov. 13:24): "He that spareth the rod hateth his son." But the virtue of vengeance consists in observing the due measure of vengeance with regard to all the circumstances.
Q: Objection 1: It seems that vengeance is not a special and distinct virtue. For just as the good are rewarded for their good deeds, so are the wicked punished for their evil deeds. Now the rewarding of the good does not belong to a special virtue, but is an act of commutative justice. Therefore in the same way vengeance should not be accounted a special virtue.

Obj. 2: Further, there is no need to appoint a special virtue for an act to which a man is sufficiently disposed by the other virtues. Now man is sufficiently disposed by the virtues of fortitude or zeal to avenge evil. Therefore vengeance should not be reckoned a special virtue.

Obj. 3: Further, there is a special vice opposed to every special virtue. But seemingly no special vice is opposed to vengeance. Therefore it is not a special virtue.
Q: Whether Vengeance Should Be Wrought by Means of Punishments Customary Among Men?

A: On the contrary,
These punishments are fixed by the divine law as appears from what we have said above (I-II, Q. 105, A. 2).

I answer that,
Vengeance is lawful and virtuous so far as it tends to the prevention of evil. Now some who are not influenced by motive of virtue are prevented from committing sin, through fear of losing those things which they love more than those they obtain by sinning, else fear would be no restraint to sin. Consequently vengeance for sin should be taken by depriving a man of what he loves most. Now the things which man loves most are life, bodily safety, his own freedom, and external goods such as riches, his country and his good name. Wherefore, according to Augustine's reckoning (De Civ. Dei xxi), "Tully writes that the laws recognize eight kinds of punishment": namely, "death," whereby man is deprived of life; "stripes," "retaliation," or the loss of eye for eye, whereby man forfeits his bodily safety; "slavery," and "imprisonment," whereby he is deprived of freedom; "exile" whereby he is banished from his country; "fines," whereby he is mulcted in his riches; "ignominy," whereby he loses his good name.

Reply Obj. 1: Our Lord forbids the uprooting of the cockle, when there is fear lest the wheat be uprooted together with it. But sometimes the wicked can be uprooted by death, not only without danger, but even with great profit, to the good. Wherefore in such a case the punishment of death may be inflicted on sinners.

Reply Obj. 2: All who sin mortally are deserving of eternal death, as regards future retribution, which is in accordance with the truth of the divine judgment. But the punishments of this life are more of a medicinal character; wherefore the punishment of death is inflicted on those sins alone which conduce to the grave undoing of others.

Reply Obj. 3: The very fact that the punishment, whether of death or of any kind that is fearsome to man, is made known at the same time as the sin, makes man's will avers to sin: because the fear of punishment is greater than the enticement of the example of sin.
