 Justice derives from nomos in the sense of a divinely ordained Law; and Hesiod emphasises that Zeus’ laws are enforced. Punishment may not be visited directly on the unjust individual, however: rather, a whole city suffers for the injustice of its leaders, and retribution may fall on a man’s descendants. Moreover, Hesiod seems at one point to waver, and allows that if the wicked go unpunished, we would not have good reason to be just (270–3). Doubts about the reliability of divine rewards and punishments are later an important part of the motivation for the immoralist challenge; in Republic Book II, Adeimantus complains that the poets are inconsistent on this point, and anyway the rewards and punishments they promise do not show what is good and bad about justice and injustice in themselves (362d–367e).
