XVIII. "You render me liable to an infinite debt of gratitude," says our opponent, "when you say 'even to those who have given any thing to our relations,' so fix some limit. He who bestows a benefit upon the son, according to you, bestows it likewise upon the father: this is the first question I wish to raise. In the next place I should like to have a clear definition of whether a benefit, if it be bestowed upon your friend's father as well as upon himself, is bestowed also upon his brother? or upon his uncle? or his grandfather? or his wife and his father-in-law? tell me where I am to stop, how far I am to follow out the pedigree of the family?" SENECA. If I cultivate your land, I bestow a benefit upon you; if I extinguish your house when burning, or prop it so as to save it from falling, I shall bestow a benefit upon you; if I heal your slave, I shall charge it to you; if I save your son's life, will you not thereby receive a benefit from me? XIX. THE ADVERSARY. Your instances are not to the purpose, for he who cultivates my land, does not benefit the land, but me; he who props my house so that it does not fall, does this service to me, for the house itself is without feeling, and as it has none, it is I who am indebted to him; and he who cultivates my land does so because he wishes to oblige me, not to oblige the land. I should say the same of a slave; he is a chattel owned by me; he is saved for my advantage, therefore I am indebted for him. My son is himself capable of receiving a benefit; so it is he who receives it; I am gratified at a benefit which comes so near to myself, but am not laid under any obligation. SE. Still I should like you, who say that you are under no obligation, to answer me this. The good health, the happiness, and the inheritance of a son are connected with his father; his father will be more happy if he keeps his son safe, and more unhappy if he loses him. What follows, then? when a man is made happier by me and is freed from the greatest danger of unhappiness, does he not receive a benefit? AD. No, because there are some things which are bestowed upon others, and yet flow from them so as to reach ourselves; yet we must ask the person upon whom it was bestowed for repayment; as for example, money must be sought from the man to whom it was lent, although it may, by some means, have come into my hands. There is no benefit whose advantages do not extend to the receiver's nearest friends, and sometimes even to those less intimately connected with him; yet we do not enquire whither the benefit has proceeded from him to whom it was first given, but where it was first placed. You must demand repayment from the defendant himself personally.
