The place of the dialogue in the series cannot be determined with certainty. The style and subject, and the treatment of the character of Socrates, have a close resemblance to the earlier dialogues, especially to the “Phaedrus” and “Euthydemus.” The manner in which the ideas are spoken of at the end of the dialogue, also indicates a comparatively early date. The imaginative element is still in full vigour; the Socrates of the “Cratylus” is the Socrates of the “Apology” and “Symposium,” not yet Platonized; and he describes, as in the “Theaetetus,” the philosophy of Heracleitus by “unsavoury” similes—he cannot believe that the world is like “a leaky vessel,” or “a man who has a running at the nose”; he attributes the flux of the world to the swimming in some folks’ heads. On the other hand, the relation of thought to language is omitted here, but is treated of in the “Sophist.” These grounds are not sufficient to enable us to arrive at a precise conclusion. But we shall not be far wrong in placing the “Cratylus” about the middle, or at any rate in the first half, of the series.
Cratylus, the Heracleitean philosopher, and Hermogenes, the brother of Callias, have been arguing about names; the former maintaining that they are natural, the latter that they are conventional. Cratylus affirms that his own is a true name, but will not allow that the name of Hermogenes is equally true. Hermogenes asks Socrates to explain to him what Cratylus means; or, far rather, he would like to know, What Socrates himself thinks about the truth or correctness of names? Socrates replies, that hard is knowledge, and the nature of names is a considerable part of knowledge: he has never been to hear the fifty-drachma course of Prodicus; and having only attended the single-drachma course, he is not competent to give an opinion on such matters. When Cratylus denies that Hermogenes is a true name, he supposes him to mean that he is not a true son of Hermes, because he is never in luck. But he would like to have an open council and to hear both sides.
Hermogenes is of opinion that there is no principle in names; they may be changed, as we change the names of slaves, whenever we please, and the altered name is as good as the original one.
You mean to say, for instance, rejoins Socrates, that if I agree to call a man a horse, then a man will be rightly called a horse by me, and a man by the rest of the world? But, surely, there is in words a true and a false, as there are true and false propositions. If a whole proposition be true or false, then the parts of a proposition may be true or false, and the least parts as well as the greatest; and the least parts are names, and therefore names may be true or false. Would Hermogenes maintain that anybody may give a name to anything, and as many names as he pleases; and would all these names be always true at the time of giving them? Hermogenes replies that this is the only way in which he can conceive that names are correct; and he appeals to the practice of different nations, and of the different Hellenic tribes, in confirmation of his view. Socrates asks, whether the things differ as the words which represent them differ:—Are we to maintain with Protagoras, that what appears is? Hermogenes has always been puzzled about this, but acknowledges, when he is pressed by Socrates, that there are a few very good men in the world, and a great many very bad; and the very good are the wise, and the very bad are the foolish; and this is not mere appearance but reality. Nor is he disposed to say with Euthydemus, that all things equally and always belong to all men; in that case, again, there would be no distinction between bad and good men. But then, the only remaining possibility is, that all things have their several distinct natures, and are independent of our notions about them. And not only things, but actions, have distinct natures, and are done by different processes. There is a natural way of cutting or burning, and a natural instrument with which men cut or burn, and any other way will fail;—this is true of all actions. And speaking is a kind of action, and naming is a kind of speaking, and we must name according to a natural process, and with a proper instrument. We cut with a knife, we pierce with an awl, we weave with a shuttle, we name with a name. And as a shuttle separates the warp from the woof, so a name distinguishes the natures of things. The weaver will use the shuttle well—that is, like a weaver; and the teacher will use the name well—that is, like a teacher. The shuttle will be made by the carpenter; the awl by the smith or skilled person. But who makes a name? Does not the law give names, and does not the teacher receive them from the legislator? He is the skilled person who makes them, and of all skilled workmen he is the rarest. But how does the carpenter make or repair the shuttle, and to what will he look? Will he not look at the ideal which he has in his mind? And as the different kinds of work differ, so ought the instruments which make them to differ. The several kinds of shuttles ought to answer in material and form to the several kinds of webs. And the legislator ought to know the different materials and forms of which names are made in Hellas and other countries. But who
