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 languageas 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 regarded from a certain point of view only。 The peculiarity of the fallacies of our own age is that we live within them； and are therefore generally unconscious of them。
Aristotle has analysed several of the same fallacies in his book 'De Sophisticis Elenchis；' which Plato； with equal command of their true nature； has preferred to bring to the test of ridicule。 At first we are only struck with the broad humour of this 'reductio ad absurdum：' gradually we perceive that some important questions begin to emerge。 Here； as everywhere else； Plato is making war against the philosophers who put words in the place of things； who tear arguments to tatters； who deny predication； and thus make knowledge impossible； to whom ideas and objects of sense have no fixedness； but are in a state of perpetual oscillation and transition。 Two great truths seem to be indirectly taught through these fallacies： （1） The uncertainty of language； which allows the same words to be used in different meanings； or with different degrees of meaning： （2） The necessary limitation or relative nature of all phenomena。 Plato is aware that his own doctrine of ideas； as well as the Eleatic Being and Not… being； alike admit of being regarded as verbal fallacies。 The sophism advanced in the Meno； 'that you cannot enquire either into what you know or do not know；' is lightly touched upon at the commencement of the Dialogue； the thesis of Protagoras； that everything is true to him to whom it seems to be true； is satirized。 In contrast with these fallacies is maintained the Socratic doctrine that happiness is gained by knowledge。 The grammatical puzzles with which the Dialogue concludes probably contain allusions to tricks of language which may have been practised by the disciples of Prodicus or Antisthenes。 They would have had more point； if we were acquainted with the writings against which Plato's humour is directed。 Most of the jests appear to have a serious meaning； but we have lost the clue to some of them； and cannot determine whether； as in the Cratylus； Plato has or has not mixed up purely unmeaning fun with his satire。
The two discourses of Socrates may be contrasted in several respects with the exhibition of the Sophists： （1） In their perfect relevancy to the subject of discussion； whereas the Sophistical discourses are wholly irrelevant： （2） In their enquir
