Book 7.30
"I have lost," say you, "the benefit which I bestowed." You are a fool, and do not understand when your loss took place; you have indeed lost it, but you did so when you gave it, the fact has only now come to light. Even in the case of those benefits which appear to be lost, gentleness will do much good; the wounds of the mind ought to be handled as tenderly as those of the body. The string, which might be disentangled by patience, is often broken by a rough pull. What is the use of abuse, or of complaints? why do you overwhelm him with reproaches? why do you set him free from his obligation? even if he be ungrateful he owes you nothing after this. What sense is there in exasperating a man on whom you have conferred great favours, so as out of a doubtful friend to make a certain enemy, and one, too, who will seek to support his own cause by defaming you, or to make men say, "I do not know what the reason is that he cannot endure a man to whom he owes so much; there must be something in the background?" Any man can asperse, even if he does not permanently stain the reputation of his betters by complaining of them; nor will any one be satisfied with imputing small crimes to them, when it is only by the enormity of his falsehood that he can hope to be believed.
