XII. It may be said, "You define a benefit as a loan which cannot be repaid: now a loan is not a desirable thing in itself." When we speak of a loan, we make use of a figure, or comparison, just as we speak of law as; the standard of right and wrong, although a standard is not a thing to be desired for its own sake. I have adopted this phrase in order to illustrate my subject: when I speak of a loan, I must be understood to mean something resembling a loan. Do you wish to know how it differs from one? I add the words "which cannot be repaid," whereas every loan both can and ought to be repaid. It is so far from being right to bestow a benefit for one's own advantage, that often, as I have explained, it is one's duty to bestow it when it involves one's own loss and risk: for instance, if I assist a man when beset by robbers, so that he gets away from them safely, or help some victim of power, and bring upon myself the party spite of a body of influential men, very, probably incurring myself the same disgrace from which I saved him, although I might have taken the other side, and looked on with safety at struggles with which I have nothing to do: if I were to give bail for one who has been condemned, and when my friend's goods were advertised for sale I were to give a bond to the effect that I would make restitution to the creditors, if, in order to save a proscribed person I myself run the risk of being proscribed. No one, when about to buy a villa at Tusculum or Tibur, for a summer retreat, because of the health of the locality, considers how many years' purchase he gives for it; this must be looked to by the man who makes a profit by it. The same is true with benefits; when you ask what return I get for them, I answer, the consciousness of a good action. "What return does one get for benefits?" Pray tell me what return one gets for righteousness, innocence, magnanimity, chastity, temperance? If you wish for anything beyond these virtues, you do not wish for the virtues themselves. For what does the order of the universe bring round the seasons? for what does the sun make the day now longer and now shorter? all these things are benefits, for they take place for our good. As it is the duty of the universe to maintain the round of the seasons, as it is the duty of the sun to vary the points of his rising and setting, and to do all these things by which we profit, without any reward, so is it the duty of man, amongst other things, to bestow benefits. Wherefore then does he give? He gives for fear that he should not give, lest he might lose an opportunity of doing a good action.
