That Plato intended to represent this accomplished Sophist as humiliated by Sokrates, is evident enough: and the words put into his mouth are suited to this purpose. The eloquent lecturer, so soon as his admiring crowd of auditors has retired, proves unable to parry the questions of a single expert dialectician who remains behind, upon a matter which appears to him almost self-evident, and upon which every one (from Homer downward) agrees with him. Besides this, however, Plato is not satisfied without making him say very simple and absurd things. All this is the personal, polemical, comic scope of the dialogue. It lends (whether well-placed or not) a certain animation and variety, which the author naturally looked out for, in an aggregate of dialogues all handling analogous matters about man and society.
But though the polemical purpose of the dialogue is thus plain, its philosophical purpose perplexes the critics considerably. They do not like to see Sokrates employing sophistry against the Sophists: that is, as they think, casting out devils by the help of Beelzebub. And certainly, upon the theory which they adopt, respecting the relation between Plato and Sokrates on one side, and the Sophists on the other, I think this dialogue is very difficult to explain. But I do not think it is difficult, upon a true theory of the Platonic writings.
Philosophical purpose of the dialogue — theory of the Dialogues of Search generally, and of Knowledge as understood by Plato.
In a former chapter, I tried to elucidate the general character and purpose of those Dialogues of Search, which occupy more than half the Thrasyllean Canon, and of which we have already reviewed two or three specimens — Euthyphron, Alkibiadês, &c. We have seen that they are distinguished by the absence of any affirmative conclusion: that they prove nothing, but only, at the most, disprove one or more supposable solutions: that they are not processes in which one man who knows communicates his knowledge to ignorant hearers, but in which all are alike ignorant, and all are employed, either in groping, or guessing, or testing the guesses of the rest. We have farther seen that the value of these Dialogues depends upon the Platonic theory about knowledge; that Plato did not consider any one to know, who could not explain to others all that he knew, reply to the cross-examination of a Sokratic Elenchus, and cross-examine others to test their knowledge: that knowledge in this sense could not be attained by hearing, or reading, or committing to memory a theorem, together with the steps of reasoning which directly conducted to it: — but that there was required, besides, an acquaintance with many counter-theorems, each having more or less appearance of truth; as well as with various embarrassing aspects and plausible delusions on the subject, which an expert cross-examiner would not fail to urge. Unless you are practised in meeting all the difficulties which he can devise, you cannot be said to know. Moreover, it is in this last portion of the conditions of knowledge, that most aspirants are found wanting.
The Hippias is an exemplification of this theory — Sokrates sets forth a case of confusion, and avows his inability to clear it up. Confusion shown up in the Lesser Hippias — Error in the Greater.
Now the Greater and Lesser Hippias are peculiar specimens of these Dialogues of Search, and each serves the purpose above indicated. The Greater Hippias enumerates a string of tentatives, each one of which ends in acknowledged failure: the Lesser Hippias enunciates a thesis, which Sokrates proceeds to demonstrate, by plausible arguments such as Hippias is forced to admit. But though Hippias admits each successive step, he still mistrusts the conclusion, and suspects that he has been misled — a feeling which Plato[70] describes elsewhere as being frequent among the respondents of Sokrates. Nay, Sokrates himself shares in the mistrust — presents himself as an unwilling propounder of arguments which force themselves upon him,[71] and complains of his own mental embarrassment. Now you may call this sophistry, if you please; and you may silence its propounders by calling them hard names. But such ethical prudery — hiding all the uncomfortable logical puzzles which start up when you begin to analyse an established sentiment, and treating them as non-existent because you refuse to look at them — is not the way, to attain what Plato calls knowledge. If there be any argument, the process of which seems indisputable, while yet its conclusion contradicts, or seems to contradict, what is known, upon other evidence — the full and patient analysis of that argument is indispensable, before you can become master of the truth and able to defend it. Until you have gone through such analysis, your mind must remain in that state of confusion which is indicated by Sokrates at the end of the Lesser Hippias. As it is a part of the process of Search, to travel in the path of the Greater Hippias — that is, to go through a string of erroneous solutions, each of which can be proved, by reasons shown, to be erroneous: so it is an equally important part of the same process, to travel in the path of the Lesser Hippias — that is, to acquaint ourselves with all those arguments, bearing on the case, in which two contrary conclusions appear to be both of them plausibly demonstrated, and in which therefore we cannot as yet determine which of them is erroneous — or whether both are not erroneous. The Greater Hippias exhibits errors, — the Lesser Hippias puts before us confusion. With both these enemies the Searcher for truth must contend: and Bacon tells us, that confusion is the worst enemy of the two — “Citius emergit veritas ex errore, quam ex confusione”. Plato, in the Lesser Hippias, having in hand a genuine Sokratic thesis, does not disdain to invest Sokrates with the task (sophistical, as some call it, yet not the less useful and instructive) of setting forth at large this case of confusion, and avowing his inability to clear it up. It is enough for Sokrates that he brings home the painful sense of confusion to the feelings of his hearer as well as to his own. In that painful sentiment lies the stimulus provocative of farther intellectual effort.[72] The dialogue ends but the process of search, far from ending along with it, is emphatically declared to be unfinished, and, to be in a condition not merely unsatisfactory but intolerable, not to be relieved except by farther investigation, which thus becomes a necessary sequel.

Καὶ ὁ Ἀδείμαντος, Ὦ Σώκρατες, ἔφη, πρὸς μὲν ταῦτά σοι οὐδεὶς ἂν οἷος τ’ εἴη ἀντειπεῖν· ἀλλὰ γὰρ τοιόνδε τι πάσχουσιν οἱ ἀκούοντες ἐκάστοτε ἂ νῦν λέγεις· ἡγοῦνται δι’ ἀπειρίαν τοῦ ἐρωτᾷν καὶ ἀποκρίνεσθαι ὑπὸ τοῦ λόγου παρ’ ἕκαστον τὸ ἐρώτημα σμικρὸν παραγόμενοι, ἀθροισθέντων τῶν σμικρῶν ἐπὶ τελευτῆς τῶν λόγων, μέγα τὸ σφάλμα καὶ ἐναντίον τοῖς πρώτοις ἀναφαίνεσθαι … ἐπει τό γε ἀληθὲς οὐδέν τι μᾶλλον ταύτῃ ἔχειν.
This passage, attesting the effect of the Sokratic examination upon the minds of auditors, ought to be laid to heart by those Platonic critics who denounce the Sophists for generating scepticism and uncertainty.
