at the conclusion that Cleinias must become a philosopher. And philosophy is the possession of knowledge; and knowledge must be of a kind which is profitable and may be used. What knowledge is there which has such a nature? Not the knowledge which is required in any particular art; nor again the art of the composer of speeches, who knows how to write them, but cannot speak them, although he too must be admitted to be a kind of enchanter of wild animals. Neither is the knowledge which we are seeking the knowledge of the general. For the general makes over his prey to the statesman, as the huntsman does to the cook, or the taker of quails to the keeper of quails; he has not the use of that which he acquires. The two enquirers, Cleinias and Socrates, are described as wandering about in a wilderness, vainly searching after the art of life and happiness. At last they fix upon the kingly art, as having the desired sort of knowledge. But the kingly art only gives men those goods which are neither good nor evil: and if we say further that it makes us wise, in what does it make us wise? Not in special arts, such as cobbling or carpentering, but only in itself: or say again that it makes us good, there is no answer to the question, 'good in what?' At length in despair Cleinias and Socrates turn to the 'Dioscuri' and request their aid.
Euthydemus argues that Socrates knows something; and as he cannot know and not know, he cannot know some things and not know others, and therefore he knows all things: he and Dionysodorus and all other men know all things. 'Do they know shoemaking, etc?' 'Yes.' The sceptical Ctesippus would like to have some evidence of this extraordinary statement: he will believe if Euthydemus will tell him how many teeth Dionysodorus has, and if Dionysodorus will give him a like piece of information about Euthydemus. Even Socrates is incredulous, and indulges in a little raillery at the expense of the brothers. But he restrains himself, remembering that if the men who are to be his teachers think him stupid they will take no pains with him. Another fallacy is produced which turns on the absoluteness of the verb 'to know.' And here Dionysodorus is caught 'napping,' and is induced by Socrates to confess that 'he does not know the good to be unjust.' Socrates appeals to his brother Euthydemus; at the same time he acknowledges that he cannot, like Heracles, fight against a Hydra, and even Heracles, on the approach of a second monster, called upon his nephew Iolaus to help. Dionysodorus rejoins that Iolaus was no more the nephew of Heracles than of Socrates. For a nephew is a nephew, and a brother is a brother, and a father is a father, not of one man only, but of all; nor of men only, but of dogs and sea-monsters. Ctesippus makes merry with the consequences which follow: 'Much good has your father got out of the wisdom of his puppies.'
'But,' says Euthydemus, unabashed, 'nobody wants much good.' Medicine is a good, arms are a good, money is a good, and yet there may be too much of them in wrong places. 'No,' says Ctesippus, 'there cannot be too much gold.' And would you be happy if you had three talents of gold in your belly, a talent in your pate, and a stater in either eye?' Ctesippus, imitating the new wisdom, replies, 'And do not the Scythians reckon those to be the happiest of men who have their skulls gilded and see the inside of them?' 'Do you see,' retorts Euthydemus, 'what has the quality of vision or what has not the quality of vision?' 'What has the quality of vision.' 'And you see our garments?' 'Yes.' 'Then our garments have the quality of vision.' A similar play of words follows, which is successfully retorted by Ctesippus, to the great delight of Cleinias, who is rebuked by Socrates for laughing at such solemn and beautiful things.
'But are there any beautiful things? And if there are such, are they the same or not the same as absolute beauty?' Socrates replies that they are not the same, but each of them has some beauty present with it. 'And are you an ox because you have an ox present with you?' After a few more amphiboliae, in which Socrates, like Ctesippus, in self-defence borrows the weapons of the brothers, they both confess that the two heroes are invincible; and the scene concludes with a grand chorus of shouting and laughing, and a panegyrical oration from Socrates:—
First, he praises the indifference of Dionysodorus and Euthydemus to public opinion; for most persons would rather be refuted by such arguments than use them in the refutation of others. Secondly, he remarks upon their impartiality; for they stop their own mouths, as well as those of other people. Thirdly, he notes their liberality, which makes them give away their secret to all the world: they should be more reserved, and let no one be present at this exhibition who does not pay them a handsome fee; or better still they might practise on one another only. He concludes with a respectful request that they will receive him and Cleinias among their disciples.
Crito tells Socrates that he has heard one of the audience criticise severely this wisdom,—not sparing Socrates himself for countenancing such an exhibition. Socrates asks what manner of man was this censorious critic. 'Not an orator, but a great composer of speeches.' Socrates understands that he is an amphibious animal, half philosopher, half politician; one of a class who have the highest opinion of themselves and a spite against philosophers, whom they imagine to be their rivals. They are a class who are very likely to get mauled by Euthydemus and his friends, and have a great notion of their own wisdom; for they imagine themselves to have all the advantages and none of the drawbacks both of politics and of philosophy. They do not understand the principles of combination, and hence are ignorant that the union of two good things which have different ends produces a compound inferior to either of them taken separately.
Crito is anxious about the education of his children, one of whom is growing up. The description of Dionysodorus and Euthydemus suggests to him the reflection that the professors of education are strange beings. Socrates consoles him with the remark that the good in all professions are few, and recommends that 'he and his house' should continue to serve philosophy, and not mind about its professors.

There is a stage in the history of philosophy in which the old is dying out, and the new has not yet come into full life. Great philosophies like the Eleatic or Heraclitean, which have enlarged the boundaries of the human mind, begin to pass away in words. They subsist only as forms which have rooted themselves in language—as troublesome elements of thought which cannot be either used or explained away. The same absoluteness which was once attributed to abstractions is now attached to the words which are the signs of them. The philosophy which in the first and second generation was a great and inspiring effort of reflection, in the third becomes sophistical, verbal, eristic.
It is this stage of philosophy which Plato satirises in the Euthydemus. The fallacies which are noted by him appear trifling to us now, but they were not trifling in the age before logic, in the decline of the earlier Greek philosophies, at a time when language was first beginning to perplex human thought. Besides he is caricaturing them; they probably received more subtle forms at the hands of those who seriously maintained them. They are patent to us in Plato, and we are inclined to wonder how any one could ever have been deceived by them; but we must remember also that there was a time when the human mind was only with great difficulty disentangled from such fallacies.
To appreciate fully the drift of the Euthydemus, we should imagine a mental state in which not individuals only, but whole schools during more than one generation, were animated by the desire to exclude the conception of rest, and therefore the very word 'this' (Theaet.) from language; in which the ideas of space, time, matter, motion, were proved to be contradictory and imaginary; in which the nature of qualitative change was a puzzle, and even differences of degree, when applied to abstract notions, were not understood; in which there was no analysis of grammar, and mere puns or plays of words received serious attention; in which contradiction itself was denied, and, on the one hand, every predicate was affirmed to be true of every subject, and on the other, it was held that no predicate was true of any subject, and that nothing was, or was known, or could be spoken. Let us imagine disputes carried on with religious earnestness and more than scholastic subtlety, in which the catchwords of philosophy are completely detached from their context. (Compare Theaet.) To such disputes the humour, whether of Plato in the ancient, or of Pope and Swift in the modern world, is the natural enemy. Nor must we forget that in modern times also there is no fallacy so gross, no trick of language so transparent, no abstraction so barren and unmeaning, no form of thought so contradictory to experience, which has not been found to satisfy the minds of philosophical enquirers at a certain stage, or when
