Plato, he is vain and boastful, yet he has also a certain dignity, and is
treated by Socrates with considerable respect. But he is no match for him
in dialectics. Although he has been teaching rhetoric all his life, he is
still incapable of defining his own art. When his ideas begin to clear up,
he is unwilling to admit that rhetoric can be wholly separated from justice
and injustice, and this lingering sentiment of morality, or regard for
public opinion, enables Socrates to detect him in a contradiction. Like
Protagoras, he is described as of a generous nature; he expresses his
approbation of Socrates' manner of approaching a question; he is quite 'one
of Socrates' sort, ready to be refuted as well as to refute,' and very
eager that Callicles and Socrates should have the game out. He knows by
experience that rhetoric exercises great influence over other men, but he
is unable to explain the puzzle how rhetoric can teach everything and know
nothing.

Polus is an impetuous youth, a runaway 'colt,' as Socrates describes him,
who wanted originally to have taken the place of Gorgias under the pretext
that the old man was tired, and now avails himself of the earliest
opportunity to enter the lists. He is said to be the author of a work on
rhetoric, and is again mentioned in the Phaedrus, as the inventor of
balanced or double forms of speech (compare Gorg.; Symp.). At first he is
violent and ill-mannered, and is angry at seeing his master overthrown.
But in the judicious hands of Socrates he is soon restored to good-humour,
and compelled to assent to the required conclusion. Like Gorgias, he is
overthrown because he compromises; he is unwilling to say that to do is
fairer or more honourable than to suffer injustice. Though he is
fascinated by the power of rhetoric, and dazzled by the splendour of
success, he is not insensible to higher arguments. Plato may have felt
that there would be an incongruity in a youth maintaining the cause of
injustice against the world. He has never heard the other side of the
