Whether a Man Is Bound to Give Thanks to Every Benefactor?
Objection 1: It seems that a man is not bound to give thanks to every benefactor. For a man may benefit himself just as he may harm himself, according to Ecclus. 14:5, "He that is evil to himself, to whom will he be good?" But a man cannot thank himself, since thanksgiving seems to pass from one person to another. Therefore thanksgiving is not due to every benefactor.
Obj. 2: Further, gratitude is a repayment of an act of grace. But some favors are granted without grace, and are rudely, slowly and grudgingly given. Therefore gratitude is not always due to a benefactor.
Obj. 3: Further, no thanks are due to one who works for his own profit. But sometimes people bestow favors for their own profit. Therefore thanks are not due to them.
Obj. 4: Further, no thanks are due to a slave, for all that he is belongs to his master. Yet sometimes a slave does a good turn to his master. Therefore gratitude is not due to every benefactor.
Obj. 5: Further, no one is bound to do what he cannot do equitably and advantageously. Now it happens at times that the benefactor is very well off, and it would be of no advantage to him to be repaid for a favor he has bestowed. Again it happens sometimes that the benefactor from being virtuous has become wicked, so that it would not seem equitable to repay him. Also the recipient of a favor may be a poor man, and is quite unable to repay. Therefore seemingly a man is not always bound to repayment for favors received.
Obj. 6: Further, no one is bound to do for another what is inexpedient and hurtful to him. Now sometimes it happens that repayment of a favor would be hurtful or useless to the person repaid. Therefore favors are not always to be repaid by gratitude.
On the contrary, It is written (1 Thess. 5:18): "In all things give thanks."
I answer that, Every effect turns naturally to its cause; wherefore Dionysius says (Div. Nom. i) that "God turns all things to Himself because He is the cause of all": for the effect must needs always be directed to the end of the agent. Now it is evident that a benefactor, as such, is cause of the beneficiary. Hence the natural order requires that he who has received a favor should, by repaying the favor, turn to his benefactor according to the mode of each. And, as stated above with regard to a father (Q. 31, A. 3; Q. 101, A. 2), a man owes his benefactor, as such, honor and reverence, since the latter stands to him in the relation of principle; but accidentally he owes him assistance or support, if he need it.
Reply Obj. 1: In the words of Seneca (1 Benef. v), "just as a man is liberal who gives not to himself but to others, and gracious who forgives not himself but others, and merciful who is moved, not by his own misfortunes but by another's, so too, no man confers a favor on himself, he is but following the bent of his nature, which moves him to resist what hurts him, and to seek what is profitable." Wherefore in things that one does for oneself, there is no place for gratitude or ingratitude, since a man cannot deny himself a thing except by keeping it. Nevertheless things which are properly spoken of in relation to others are spoken of metaphorically in relation to oneself, as the Philosopher states regarding justice (Ethic. v, 11), in so far, to wit, as the various parts of man are considered as though they were various persons.
