text: The wise man will inquire in his own mind into all the circumstances: how much he has received, from whom, when, where, how. And so we declare that none but the wise man knows how to make return for a favour; moreover, none but the wise man knows how to confer a benefit, – that man, I mean, who enjoys the giving more than the recipient enjoys the receiving. Now some person will reckon this remark as one of the generally surprising statements such as we Stoics are wont to make and such as the Greeks call "paradoxes," and will say: "Do you maintain, then, that only the wise man knows how to return a favour? Do you maintain that no one else knows how to make restoration to a creditor for a debt? Or, on buying a commodity, to pay full value to the seller?" In order not to bring any odium upon myself, let me tell you that Epicurus says the same thing. At any rate, Metrodorus remarks that only the wise man knows how to return a favour. Again, the objector mentioned above wonders at our saying: "The wise man alone knows how to love, the wise man alone is a real friend." And yet it is a part of love and of friendship to return favours; nay, further, it is an ordinary act, and happens more frequently than real friendship. Again, this same objector wonders at our saying, "There is no loyalty except in the wise man," just as if he himself does not say the same thing! Or do you think that there is any loyalty in him who does not know how to return a favour? These men, accordingly, should cease to discredit us, just as if we were uttering an impossible boast; they should understand that the essence of honour resides in the wise man, while among the crowd we find only the ghost and the semblance of honour. None but the wise man knows how to return a favour. Even a fool can return it in proportion to his knowledge and his power; his fault would be a lack of knowledge rather than a lack of will or desire. To will does not come by teaching.
