Book 3.6

The question has been raised, whether this most odious vice ought to go unpunished; and whether the law commonly made use of in the schools, by which we can proceed against a man for ingratitude, ought to be adopted by the State also, since all men agree that it is just. "Why not?" you may say, "seeing that even cities cast in each other's teeth the services which they have performed to one another, and demand from the children some return for benefits conferred upon their fathers?" On the other hand, our ancestors, who were most admirable men, made demands upon their enemies alone, and both gave and lost their benefits with magnanimity. With the exception of Macedonia, no nation has ever established an action at law for ingratitude. And this is a strong argument against its being established, because all agree in blaming crime; and homicide, poisoning, parricide, and sacrilege are visited with different penalties in different countries, but everywhere with some penalty; whereas this most common vice is nowhere punished, though it is everywhere blamed. We do not acquit it; but as it would be most difficult to reckon accurately the penalty for so varying a matter, we condemn it only to be hated, and place it upon the list of those crimes which we refer for judgment to the gods.
