'But, Socrates, as I was telling you, Cratylus mystifies me; I should like to ask him, in your presence, what he means by the fitness of names?' To this appeal, Cratylus replies 'that he cannot explain so important a subject all in a moment.' 'No, but you may "add little to little," as Hesiod says.' Socrates here interposes his own request, that Cratylus will give some account of his theory. Hermogenes and himself are mere sciolists, but Cratylus has reflected on these matters, and has had teachers. Cratylus replies in the words of Achilles: '"Illustrious Ajax, you have spoken in all things much to my mind," whether Euthyphro, or some Muse inhabiting your own breast, was the inspirer.' Socrates replies, that he is afraid of being self-deceived, and therefore he must 'look fore and aft,' as Homer remarks. Does not Cratylus agree with him that names teach us the nature of things? 'Yes.' And naming is an art, and the artists are legislators, and like artists in general, some of them are better and some of them are worse than others, and give better or worse laws, and make better or worse names. Cratylus cannot admit that one name is better than another; they are either true names, or they are not names at all; and when he is asked about the name of Hermogenes, who is acknowledged to have no luck in him, he affirms this to be the name of somebody else. Socrates supposes him to mean that falsehood is impossible, to which his own answer would be, that there has never been a lack of liars. Cratylus presses him with the old sophistical argument, that falsehood is saying that which is not, and therefore saying nothing;--you cannot utter the word which is not.
Socrates complains that this argument is too subtle for an old man to understand: Suppose a person addressing Cratylus were to say, Hail, Athenian Stranger, Hermogenes! would these words be true or false? 'I should say that they would be mere unmeaning sounds, like the hammering of a brass pot.' But you would acknowledge that names, as well as pictures, are imitations, and also that pictures may give a right or wrong representation of a man or woman:--why may not names then equally give a representation true and right or false and wrong? Cratylus admits that pictures may give a true or false representation, but denies that names can. Socrates argues, that he may go up to a man and say 'this is year picture,' and again, he may go and say to him 'this is your name'--in the one case appealing to his sense of sight, and in the other to his sense of hearing;--may he not? 'Yes.' Then you will admit that there is a right or a wrong assignment of names, and if of names, then of verbs and nouns; and if of verbs and nouns, then of the sentences which are made up of them; and comparing nouns to pictures, you may give them all the appropriate sounds, or only some of them. And as he who gives all the colours makes a good picture, and he who gives only some of them, a bad or imperfect one, but still a picture; so he who gives all the sounds makes a good name, and he who gives only some of them, a bad or imperfect one, but a name still. The artist of names, that is, the legislator, may be a good or he may be a bad artist. 'Yes, Socrates, but the cases are not parallel; for if you subtract or misplace a letter, the name ceases to be a name.' Socrates admits that the number 10, if an unit is subtracted, would cease to be 10, but denies that names are of this purely quantitative nature. Suppose that there are two objects--Cratylus and the image of Cratylus; and let us imagine that some God makes them perfectly alike, both in their outward form and in their inner nature and qualities: then there will be two Cratyluses, and not merely Cratylus and the image of Cratylus. But an image in fact always falls short in some degree of the original, and if images are not exact counterparts, why should names be? if they were, they would be the doubles of their originals, and indistinguishable from them; and how ridiculous would this be! Cratylus admits the truth of Socrates' remark. But then Socrates rejoins, he should have the courage to acknowledge that letters may be wrongly inserted in a noun, or a noun in a sentence; and yet the noun or the sentence may retain a meaning. Better to admit this, that we may not be punished like the traveller in Egina who goes about at night, and that Truth herself may not say to us, 'Too late.'
And, errors excepted, we may still affirm that a name to be correct must have proper letters, which bear a resemblance to the thing signified. I must remind you of what Hermogenes and I were saying about the letter rho accent, which was held to be expressive of motion and hardness, as lambda is of smoothness;--and this you will admit to be their natural meaning.
But then, why do the Eritreans call that skleroter which we call sklerotes?
We can understand one another, although the letter rho accent is not equivalent to the letter s: why is this? You reply, because the two letters are sufficiently alike for the purpose of expressing motion. Well, then, there is the letter lambda; what business has this in a word meaning hardness? 'Why, Socrates, I retort upon you, that we put in and pull out letters at pleasure.' And the explanation of this is custom or agreement: we have made a convention that the rho shall mean s and a convention may indicate by the unlike as well as by the like. How could there be names for all the numbers unless you allow that convention is used? Imitation is a poor thing, and has to be supplemented by convention, which is another poor thing; although I agree with you in thinking that the most perfect form of language is found only where there is a perfect correspondence of sound and meaning. But let me ask you what is the use and force of names?
