Protagoras.
Introduction.

'he, above all other men, is bound to say "that wisdom and knowledge are the highest of human things."'

There is no reason to suppose that in all this Plato is depicting an imaginary Protagoras; he seems to be showing us the teaching of the Sophists under the milder aspect under which he once regarded them. Nor is there any reason to doubt that Socrates is equally an historical character, paradoxical, ironical, tiresome, but seeking for the unity of virtue and knowledge as for a precious treasure; willing to rest this even on a calculation of pleasure, and irresistible here, as everywhere in Plato, in his intellectual superiority.

The aim of Socrates, and of the Dialogue, is to show the unity of virtue. In the determination of this question the identity of virtue and knowledge is found to be involved. But if virtue and knowledge are one, then virtue can be taught; the end of the Dialogue returns to the beginning. Had Protagoras been allowed by Plato to make the Aristotelian distinction, and say that virtue is not knowledge, but is accompanied with knowledge; or to point out with Aristotle that the same quality may have more than one opposite; or with Plato himself in the Phaedo to deny that good is a mere exchange of a greater pleasure for a less—the unity of virtue and the identity of virtue and knowledge would have required to be proved by other arguments.

The victory of Socrates over Protagoras is in every way complete when their minds are fairly brought together. Protagoras falls before him after two or three blows. Socrates partially gains his object in the first part of the Dialogue, and completely in the second. Nor does he appear at any disadvantage when subjected to 'the question' by Protagoras. He succeeds in making his two 'friends,' Prodicus and Hippias, ludicrous by the way; he also makes a long speech in defence of the poem of Simonides, after the manner of the Sophists, showing, as Alcibiades says, that he is only pretending to have a bad memory, and that he and not Protagoras is really a master in the two styles of speaking; and that he can undertake, not one side of the argument only, but both, when Protagoras begins to break down. Against the authority of the poets with whom Protagoras has ingeniously identified himself at the commencement of the Dialogue, Socrates sets up the proverbial philosophers and those masters of brevity the Lacedae-
