The dialogue naturally falls into three divisions, to which the three characters of Gorgias, Polus, and Callicles respectively correspond; and the form and manner change with the stages of the argument. Socrates is deferential towards Gorgias, playful and yet cutting in dealing with the youthful Polus, ironical and sarcastic in his encounter with Callicles. In the first division the question is asked—What is rhetoric? To this there is no answer given, for Gorgias is soon made to contradict himself by Socrates, and the argument is transferred to the hands of his disciple Polus, who rushes to the defence of his master. The answer has at last to be given by Socrates himself, but before he can even explain his meaning to Polus, he must enlighten him upon the great subject of shams or flatteries. When Polus finds his favourite art reduced to the level of cookery, he replies that at any rate rhetoricians, like despots, have great power. Socrates denies that they have any real power, and hence arise the three paradoxes already mentioned. Although they are strange to him, Polus is at last convinced of their truth; at least, they seem to him to follow legitimately from the premises. Thus the second act of the dialogue closes. Then Callicles appears on the scene, at first maintaining that pleasure is good, and that might is right, and that law is nothing but the combination of the many weak against the few strong. When he is confuted he withdraws from the argument, and leaves Socrates to arrive at the conclusion by himself. The conclusion is that there are two kinds of statesmanship, a higher and a lower—that which makes the people better, and that which only flatters them, and he exhorts Callicles to choose the higher. The dialogue terminates with a mythus of a final judgment, in which there will be no more flattery or disguise, and no further use for the teaching of rhetoric.
The characters of the three interlocutors also correspond to the parts which are assigned to them. Gorgias is the great rhetorician, now advanced in years, who goes from city to city displaying his talents, and is celebrated throughout Greece. Like all the Sophists in the dialogues of 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 (462 C), and is again mentioned in the “Phaedrus” (267 B), as the inventor of balanced or double forms of speech (compare “Gorgias” 448 C, 467 C; “Symposium” 185 C). 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 question, and he listens to the paradoxes, as they appear to him, of Socrates with evident astonishment. He can hardly understand the meaning of Archelaus being miserable, or of rhetoric being only useful in self-accusation. When the argument with him has fairly run out.
Callicles, in whose house they are assembled, is introduced on the stage: he is with difficulty convinced that Socrates is in earnest; for if these things are true, then, as he says with real emotion, the foundations of society are upside down. In him another type of character is represented; he is neither sophist nor philosopher, but man of the world, and an accomplished Athenian gentleman. He might be described in modern language as a cynic or materialist, a lover of power and also of pleasure, and unscrupulous in his means of attaining both. There is no desire on his part to offer any compromise in the interests of morality; nor is any concession made by him. Like Thrasymachus in the Republic, though he is not of the same weak and vulgar class, he consistently maintains that might is right. His great motive of action is political ambition; in this he is characteristically Greek. Like Anytus in the “Meno,” he is the enemy of the Sophists; but favours the new art of rhetoric, which he regards as an excellent weapon of attack and defence. He is a despiser of mankind as he is of philosophy, and sees in
