In any inquiry into the nature of justice we get little help from the wisdom of the ancients. They wrestled with the question but seem to have been as puzzled as we of today. Indeed, Plato represents the sage Socrates as frankly confessing his inability to answer satisfactorily the persistent question "What is justice?" The question comes up for discussion by Socrates and some friends at the home of Cephalus at the Piraeus. Socrates criticizes and punctures the definitions advanced by the others until Thrasymachus, apparently with some heat, challenges Socrates to give an answer of his own to the question "what is justice?" and not to content himself, nor to consume time, with merely refuting others. After some further discussion of various aspects of the question, Socrates finally says, "I have gone from one subject to another without having discovered what I sought at first, the nature of justice. I left the inquiry and turned away to consider whether justice is virtue and wisdom, or evil and folly, and when there arose a further question about the comparative advantages of justice and injustice I could not refrain from passing on to that. The result of the whole discussion has been that I know nothing at all. I know not what justice is and therefore am not likely to know whether or not it is a virtue, nor can I say whether the just man is happy or unhappy." Granting that the confession may have been intended ironically, the further discussion did not result in any practical solution, even if in one possible in Plato's ideal, but impossible, state. Indeed, the inquiry is not yet closed and will not be until the millennium. Still, upon a question so old, so important, so persistent, so ingrained in human society, and even now receiving such diverse and conflicting answers, a brief consideration of the earlier beliefs and theories may not be useless. As said by Bishop Stubbs, the historian, "The roots of the present lie deep in the past and nothing in the past is dead to him who would learn how the present came to be what it is." The roots should be examined by him who would understand the tree. In Homer we get a glimpse of a theory of his time, to wit, that each separate decision given by the magistrate in any litigated controversy was furnished to him by Zeus specially for that case. The Greek word for such a decision was _themis_, and it was supposed that somewhere in the Pantheon was a corresponding deity whose special function was to furnish the appropriate themis for each case. This deity was shadowily personified as the goddess Themis, the daughter of heaven and earth, the companion and counselor of Zeus. It was she who summoned gods and men to council and presided unseen over their deliberations. Hence she came to be regarded as also the spirit of order without which the Greek philosophers, notably Plato, held there could be no justice.
