remains a difficulty which seems to demand a more exact answer: In what relation does the satirical or etymological portion of the dialogue stand to the serious? Granting all that can be said about the provoking irony of Socrates, about the parody of Euthyphro, or Prodicus, or Antisthenes, how does the long catalogue of etymologies furnish any answer to the question of Hermogenes, which is evidently the main thesis of the dialogue: What is the truth, or correctness, or principle of names?
After illustrating the nature of correctness by the analogy of the arts, and then, as in the Republic, ironically appealing to the authority of the Homeric poems, Socrates shows that the truth or correctness of names can only be ascertained by an appeal to etymology. The truth of names is to be found in the analysis of their elements. But why does he admit etymologies which are absurd, based on Heracleitean fancies, fourfold interpretations of words, impossible unions and separations of syllables and letters?
1. The answer to this difficulty has been already anticipated in part: Socrates is not a dogmatic teacher, and therefore he puts on this wild and fanciful disguise, in order that the truth may be permitted to appear: 2. as Benfey remarks, an erroneous example may illustrate a principle of language as well as a true one: 3. many of these etymologies, as, for example, that of dikaion, are indicated, by the manner in which Socrates speaks of them, to have been current in his own age: 4. the philosophy of language had not made such progress as would have justified Plato in propounding real derivations. Like his master Socrates, he saw through the hollowness of the incipient sciences of the day, and tries to move in a circle apart from them, laying down the conditions under which they are to be pursued, but, as in the Timaeus, cautious and tentative, when he is speaking of actual phenomena. To have made etymologies seriously, would have seemed to him like the interpretation of the myths in the Phaedrus, the task 'of a not very fortunate individual, who had a great deal of time on his hands.' The irony of Socrates places him above and beyond the errors of his contemporaries.
The Cratylus is full of humour and satirical touches: the inspiration which comes from Euthyphro, and his prancing steeds, the light admixture of quotations from Homer, and the spurious dialectic which is applied to them; the jest about the fifty-drachma course of Prodicus, which is declared on the best authority, viz. his own, to be a complete education in grammar and rhetoric; the double explanation of the name Hermogenes, either as 'not being in luck,' or 'being no speaker;' the dearly-bought wisdom of Callias, the Lacedaemonian whose name was 'Rush,' and, above all, the pleasure which Socrates expresses in his own dangerous discoveries, which 'to-morrow he will purge away,' are truly humorous. While delivering a lecture on the philosophy of language, Socrates is also satirizing the endless fertility of the human mind in spinning arguments out of nothing, and employing the most trifling and fanciful analogies in support of a theory. Etymology in ancient as in modern times was a favourite recreation; and Socrates makes merry at the expense of the etymologists. The simplicity of Hermogenes, who is ready to believe anything that he is told, heightens the effect. Socrates in his genial and ironical mood hits right and left at his adversaries: Ouranos is so called apo tou oran ta ano, which, as some philosophers say, is the way to have a pure mind; the sophists are by a fanciful explanation converted into heroes; 'the givers of names were like some philosophers who fancy that the earth goes round because their heads are always going round.' There is a great deal of 'mischief' lurking in the following: 'I found myself in greater perplexity about justice than I was before I began to learn;' 'The rho in katoptron must be the addition of some one who cares nothing about truth, but thinks only of putting the mouth into shape;' 'Tales and falsehoods have generally to do with the Tragic and goatish life, and tragedy is the place of them.' Several philosophers and sophists are mentioned by name: first, Protagoras and Euthydemus are assailed; then the interpreters of Homer, oi palaioi Omerikoi (compare Arist. Met.) and the Orphic poets are alluded to by the way; then he discovers a hive of wisdom in the philosophy of Heracleitus;— the doctrine of the flux is contained in the word ousia (= osia the pushing principle), an anticipation of Anaxagoras is found in psuche and selene. Again, he ridicules the arbitrary methods of pulling out and putting in letters which were in vogue among the philologers of his time; or slightly scoffs at contemporary religious beliefs. Lastly, he is impatient of hearing from the half-converted Cratylus the doctrine that falsehood can neither be spoken, nor uttered, nor addressed; a piece of sophistry attributed to Gorgias, which reappears in the Sophist. And he proceeds to demolish, with no less delight than he had set up, the Heracleitean theory of language.
In the latter part of the dialogue Socrates becomes more serious, though he does not lay aside but rather aggravates his banter of the Heracleiteans, whom here, as in the Theaetetus, he delights to ridicule. What was the origin of this enmity we can hardly determine:—was it due to the natural dislike which may be supposed to exist between the 'patrons of the flux' and the 'friends of the ideas' (Soph.)? or is it to be attributed to the indignation which Plato felt at having wasted his time upon 'Cratylus and the doctrines of Heracleitus' in the days of his youth? Socrates, touching on some of the characteristic difficulties of early Greek philosophy, endeavours to show Cratylus that imitation may be partial or imperfect, that a knowledge of things is higher than a knowledge of names, and that there can be no knowledge if all things are in a state of transition. But Cratylus, who does not easily apprehend the argument from common sense, remains unconvinced, and on the whole inclines to his former opinion. Some profound philosophical remarks are scattered up and down, admitting of an application not only to language but to knowledge generally; such as the assertion that 'consistency is no test of truth:' or again, 'If we are over-precise about words, truth will say "too late" to us as to the belated traveller in Aegina.'
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.
