SOCRATES: They are the men to whom I should attribute the imposition of names. Even in foreign names, if you analyze them, a meaning is still discernible. For example, that which we term ousia is by some called esia, and by others again osia. Now that the essence of things should be called estia, which is akin to the first of these (esia = estia), is rational enough. And there is reason in the Athenians calling that estia which participates in ousia. For in ancient times we too seem to have said esia for ousia, and this you may note to have been the idea of those who appointed that sacrifices should be first offered to estia, which was natural enough if they meant that estia was the essence of things. Those again who read osia seem to have inclined to the opinion of Heracleitus, that all things flow and nothing stands; with them the pushing principle (othoun) is the cause and ruling power of all things, and is therefore rightly called osia. Enough of this, which is all that we who know nothing can affirm. Next in order after Hestia we ought to consider Rhea and Cronos, although the name of Cronos has been already discussed. But I dare say that I am talking great nonsense. HERMOGENES: Why, Socrates? SOCRATES: My good friend, I have discovered a hive of wisdom. HERMOGENES: Of what nature? SOCRATES: Well, rather ridiculous, and yet plausible. HERMOGENES: How plausible? SOCRATES: I fancy to myself Heracleitus repeating wise traditions of antiquity as old as the days of Cronos and Rhea, and of which Homer also spoke. HERMOGENES: How do you mean? SOCRATES: Heracleitus is supposed to say that all things are in motion and nothing at rest; he compares them to the stream of a river, and says that you cannot go into the same water twice. HERMOGENES: That is true. SOCRATES: Well, then, how can we avoid inferring that he who gave the names of Cronos and Rhea to the ancestors of the Gods, agreed pretty much in the doctrine of Heracleitus? Is the giving of the names of streams to both of them purely accidental? Compare the line in which Homer, and, as I believe, Hesiod also, tells of “Ocean, the origin of Gods, and mother Tethys (Il.—the line is not found in the extant works of Hesiod.).” And again, Orpheus says, that “The fair river of Ocean was the first to marry, and he espoused his sister Tethys, who was his mother’s daughter.” You see that this is a remarkable coincidence, and all in the direction of Heracleitus. HERMOGENES: I think that there is something in what you say, Socrates; but I do not understand the meaning of the name Tethys. SOCRATES: Well, that is almost self-explained, being only the name of a spring, a little disguised; for that which is strained and filtered (diattomenon, ethoumenon) may be likened to a spring, and the name Tethys is made up of these two words. HERMOGENES: The idea is ingenious, Socrates. SOCRATES: To be sure. But what comes next?—of Zeus we have spoken. HERMOGENES: Yes.
