Book 7.23

When you distrust those whom you order to do anything, you ought to command them to do more than enough in order that they may do what is enough. The purpose of all exaggeration is to arrive at the truth by falsehood. Consequently, he who spoke of horses as being:

"Whiter than snows and swifter than the winds,"

said what could not possibly be in order that they might be thought to be as much so as possible. And he who said:

"More firm than crags, more headlong than the stream,"

did not suppose that he should make any one believe that a man could ever be as firm as a crag. Exaggeration never hopes all its daring flights to be believed, but affirms what is incredible, that thereby it may convey what is credible. When we say, "let the man who has bestowed a benefit, forget it," what we mean is, "let him be as though he had forgotten it; let not his remembrance of it appear or be seen." When we say that repayment of a benefit ought not to be demanded, we do not utterly forbid its being demanded; for repayment must often be extorted from bad men, and even good men require to be reminded of it. Am I not to point out a means of repayment to one who does not perceive it? Am I not to explain my wants to one does not know them? Why should he (if a bad man) have the excuse, or (if a good man) have the sorrow of not knowing them? Men ought sometimes to be reminded of their debts, though with modesty, not in the tone of one demanding a legal right.
