In the preceding books I seem to have accomplished the object which I proposed to myself, since in them I have discussed how a benefit ought to be bestowed, and how it ought to be received. These are the limits of this action; when I dwell upon it further I am not obeying the orders, but the caprices of my subject which ought to be followed whither it leads, not whither it allures us to wander; for now and then something will arise, which, although it is all but unconnected with the subject, instead of being a necessary part of it, still thrills the mind with a certain charm. However, since you wish it to be so, let us go on, after having completed our discussion of the heads of the subject itself, to investigate those matters which, if you wish for truth, I must call adjacent to it, not actually connected with it; to examine which carefully is not one worth one's while, and yet is not labour in vain. No praise, however, which I can give to benefits does justice to you, Aebutius Liberalis, a man of excellent disposition and naturally inclined to bestow them. Never have I seen any one esteem even the most trifling services more kindly; indeed, your good-nature goes so far as to regard whatever benefit is bestowed upon anyone as bestowed upon yourself; you are prepared to pay even what is owed by the ungrateful, that no one may regret having bestowed benefits. You yourself are so far from any boastfulness, you are so eager at once to free those whom you serve from any feeling of obligation to you, that you like, when giving anything to any one, to seem not so much to be giving a present as returning one; and therefore what you give in this manner will all the more fully he repaid to you: for, as a rule, benefits come to one who does not demand repayment of them; and just as glory follows those who avoid it, so men receive a more plentiful harvest in return for benefits bestowed upon those who had it in their power to be ungrateful. With you there is no reason why those who have received benefits from you should not ask for fresh ones; nor would you refuse to bestow others, to overlook and conceal what you have given, and to add to it more and greater gifts, since it is the aim of all the best men and the noblest dispositions to bear with an ungrateful man until you make him grateful. Be not deceived in pursuing this plan; vice, if you do not too soon begin to hate it, will yield to virtue.
