XVI. If, however, you ask me what I really think, and wish me to give a definite answer, I should say that the one party ought to consider his benefit to have been returned, while the other ought to feel that he has not returned it; the one should release his friend from the debt, the other should hold himself bound to pay it; the one should say, "I have received;" the other should answer, "I owe." In our whole investigation, we ought to look entirely to the public good; we ought to prevent the ungrateful having any excuses in which they can take refuge, and under cover of which they can disown their debts. "I have done all in my power," say you. Well, keep on doing so still. Do you suppose that our ancestors were so foolish, as not to understand that it is most unjust that the man who has wasted the money which he received from his creditor on debauchery, or gambling, should be classed with one who has lost his own property as well as that of others in a fire, by robbery, or some sadder mischance? They would take no excuse, that men might understand that they were always bound to keep their word; it was thought better that even a good excuse should not be accepted from a few persons, than that all men should be led to try to make excuses. You say that you have done all in your power to repay your debt; this ought to be enough for your friend, but not enough for you. He to whom you owe a kindness, is unworthy of gratitude if he lets all your anxious care and trouble to repay it go for nothing; and so, too, if your friend takes your good will as a repayment, you are ungrateful if you are not all the more eager to feel the obligation of the debt which he has forgiven you. Do not snap up his receipt, or call witnesses to prove it; rather seek opportunities for repaying not less than before; repay the one man because he asks for repayment, the other because he forgives you your debt; the one because he is good, the other because he is bad. You, need not, therefore, think that you have anything to do with the question whether a man be bound to repay the benefit which he has received from a wise man, if that man has ceased to be wise and has turned into a bad man. You would return a deposit which you had received from a wise man; you would return a loan even to a bad man; what grounds have you for not returning a benefit also? Because he has changed, ought he to change you? What? if you had received anything from a man when healthy, would you not return it to him when he was sick, though we always are more bound to treat our friends with more kindness when they are ailing? So, too, this man is sick in his mind; we ought to help him, and bear with him; folly is a disease of the mind.
