We have been discoursing all this while how far a wicked man may be obliged, and the Stoics tell us at last, that he cannot be obliged at all. For they make him incapable of any good, and consequently of any benefit. But he has this advantage, that if he cannot be obliged, he cannot be ungrateful: for if he cannot receive, he is not bound to return. On the other side, a good man and an ungrateful, are a contradiction: so that at this rate there is no such thing as ingratitude in nature. They compare a wicked man’s mind to a vitiated stomach; he corrupts whatever he receives, and the best nourishment turns to the disease. But taking this for granted, a wicked man may yet so far be obliged as to pass for ungrateful, if he does not requite what he receives: for though it be not a perfect benefit, yet he receives something like it. There are goods of the mind, the body, and of fortune. Of the first sort, fools and wicked men are wholly incapable; to the rest they may be admitted. But why should I call any man ungrateful, you will say, for not restoring that which I deny to be a benefit? I answer, that if the receiver take it for a benefit, and fails of a return, it is ingratitude in him: for that which goes for an obligation among wicked men, is an obligation upon them: and they may pay one another in their own coin; the money is current, whether it be gold or leather, when it comes once to be authorized. Nay, Cleanthes carries it farther; he that is wanting, says he, to a kind office, though it be no benefit, would have done the same thing if it had been one; and is as guilty as a thief is, that has set his booty, and is already armed and mounted with a purpose to seize it, though he has not yet drawn blood. Wickedness is formed in the heart; and the matter of fact is only the discovery and the execution of it.
