But to return to justice. Hesiod, as we have already seen, makes this the whole basis of man’s relation to his fellows; on just actions and labor depends all prosperity; injustice injures the doer no less than the object of the wrong, and in the end is sure of punishment. Indeed according to the poet justice is what distinguishes man from the lower animals: “Perses, put these words now in thy heart, and harken to justice, but forget violence utterly. For this the son of Cronos has established as a rule for men. Fishes and wild beasts and winged birds he ordained should devour one another, since there is no justice among them; but to man he has given justice, which is by far the best.”[62] The theme of justice in human relations is developed into injunctions to be kind to the stranger, the suppliant, and the orphan, to respect parents, to regard another’s bed, and to give hospitality to one’s friends. Yet it must be said that Hesiod’s social morality is strictly utilitarian, not altruistic; indeed there is something in his poem which reminds us of the maxim “An eye for an eye, and a tooth for a tooth,” as when he writes: “If thy friend is the first to do thee an unkindness either in word or deed, remember to return him twofold; but if he would bring thee again into friendship and consent to render thee justice, accept it.”[63] But we must remember that this was the almost universal teaching among the Greeks down to the end of the fifth century. Justice, however, is more than a social virtue between men; it is the chief attribute of Zeus, personified as his daughter and constant attendant: “Justice is the daughter of Zeus, glorified and honored by the gods who hold Olympus; and whenever anyone does her wrong with perverse blame, straightway she sits by Zeus, son of Cronos, and she tells him the thoughts of unjust men, that the people may pay for the folly of the princes who by their wrongful purposes and crooked speeches turn judgments from the right course.”[64] In his work of defending justice Zeus is aided not only by his daughter, but by a host of watchful guardians, intermediaries who report mortals’ deeds: “Thrice ten thousand are the immortal servants of Zeus upon the rich earth, who watch mortal men. Clad in mist they fare to and fro on the earth watching deeds of justice and wrongful acts.”[65] Justice then never fails to bring sooner or later the due return to right and wrong actions; from her and the watchful messengers of Zeus there is no escape. The Homeric man had recognized that righteousness is better than evil and that the wicked are constantly threatened by punishment; but Hesiod in his Works and Days goes somewhat further than Homer, in that he makes justice a necessary attribute of the gods as well as of men.
