Book 7.18

With regard to the other class of benefit, the question arises whether if I was not able to take it without being a wise man, I am able to return it, except to a wise man. For suppose I do return it to him, he cannot receive it, he is not any longer able to receive such a thing, he has lost the knowledge of how to use it. You would not bid me throw back a ball to a man who has lost his hand; it is folly to give any one what he cannot receive. If I am to begin to reply to the last argument, I say that I should not give him what he is unable to take; but I would return it, even though he is not able to receive it. I cannot lay him under an obligation unless he takes my bounty; but by returning it I can free myself from my obligations to him. You say, "he will not be able to use it." Let him see to that; the fault will lie with him, not with me.
