Book 6.10

Let us turn our attention to the first of these. Can you desire me to do anything to express my gratitude to a man who did nothing in order to confer a benefit upon me? Passing on to the next, do you wish me to show my gratitude to such a man, and of my own will to return to him what I received from him against his will? What am I to say of the third, he who, meaning to do an injury, blunders into bestowing a benefit? That you should have wished to confer a benefit upon me is not sufficient to render me grateful; but that you should have wished not to do so is enough to set me free from any obligation to you. A mere wish does not constitute a benefit; and just as the best and heartiest wish is not a benefit when fortune prevents its being carried into effect, neither is what fortune bestows upon us a benefit, unless good wishes preceded it. In order to lay me under an obligation, you must not merely do me a service, but you must do so intentionally.
