“You render me liable to an infinite debt of gratitude,” says our opponent, “when you say ‘even to those who have given anything 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?
