“If,” our adversary may say, “you wish to imitate the gods, then bestow benefits upon the ungrateful as well as the grateful; for the sun rises upon the wicked as well as the good, the seas are open even to pirates.” By this question he really asks whether a good man would bestow a benefit upon an ungrateful person, knowing him to be ungrateful. Allow me here to introduce a short explanation, that we may not be taken in by a deceitful question. Understand that according to the system of the Stoics there are two classes of ungrateful persons. One man is ungrateful because he is a fool; a fool is a bad man; a man who is bad possesses every vice: therefore he is ungrateful. In the same way we speak of all bad men as dissolute, avaricious, luxurious, and spiteful, not because each man has all these vices in any great or remarkable degree, but because he might have them; they are in him, even though they be not seen. The second form of ungrateful person is he who is commonly meant by the term, one who is inclined by nature to this vice. In the case of him who has the vice of ingratitude just as he has every other, a wise man will bestow a benefit, because if he sets aside all such men there will be no one left for him to bestow it on.
