the rest--How will you choose between them? 'I should say, Socrates, that the art of persuasion, which gives freedom to all men, and to individuals power in the state, is the greatest good.' But what is the exact nature of this persuasion?--is the persevering retort: You could not describe Zeuxis as a painter, or even as a painter of figures, if there were other painters of figures; neither can you define rhetoric simply as an art of persuasion, because there are other arts which persuade, such as arithmetic, which is an art of persuasion about odd and even numbers. Gorgias is made to see the necessity of a further limitation, and he now defines rhetoric as the art of persuading in the law courts, and in the assembly, about the just and unjust. But still there are two sorts of persuasion: one which gives knowledge, and another which gives belief without knowledge; and knowledge is always true, but belief may be either true or false,--there is therefore a further question: which of the two sorts of persuasion does rhetoric effect in courts of law and assemblies? Plainly that which gives belief and not that which gives knowledge; for no one can impart a real knowledge of such matters to a crowd of persons in a few minutes. And there is another point to be considered:--when the assembly meets to advise about walls or docks or military expeditions, the rhetorician is not taken into counsel, but the architect, or the general. How would Gorgias explain this phenomenon? All who intend to become disciples, of whom there are several in the company, and not Socrates only, are eagerly asking:--About what then will rhetoric teach us to persuade or advise the state?
Gorgias illustrates the nature of rhetoric by adducing the example of Themistocles, who persuaded the Athenians to build their docks and walls, and of Pericles, whom Socrates himself has heard speaking about the middle wall of the Piraeus. He adds that he has exercised a similar power over the patients of his brother Herodicus. He could be chosen a physician by the assembly if he pleased, for no physician could compete with a rhetorician in popularity and influence. He could persuade the multitude of anything by the power of his rhetoric; not that the rhetorician ought to abuse this power any more than a boxer should abuse the art of self- defence. Rhetoric is a good thing, but, like all good things, may be unlawfully used. Neither is the teacher of the art to be deemed unjust because his pupils are unjust and make a bad use of the lessons which they have learned from him.
Socrates would like to know before he replies, whether Gorgias will quarrel with him if he points out a slight inconsistency into which he has fallen, or whether he, like himself, is one who loves to be refuted. Gorgias declares that he is quite one of his sort, but fears that the argument may be tedious to the company. The company cheer, and Chaerephon and Callicles exhort them to proceed. Socrates gently points out the supposed inconsistency into which Gorgias appears to have fallen, and which he is inclined to think may arise out of a misapprehension of his own. The rhetorician has been declared by Gorgias to be more persuasive to the ignorant than the physician, or any other expert. And he is said to be ignorant, and this ignorance of his is regarded by Gorgias as a happy condition, for he has escaped the trouble of learning. But is he as ignorant of just and unjust as he is of medicine or building? Gorgias is compelled to admit that if he did not know them previously he must learn them from his teacher as a part of the art of rhetoric. But he who has learned carpentry is a carpenter, and he who has learned music is a musician, and he who has learned justice is just. The rhetorician then must be a just man, and rhetoric is a just thing. But Gorgias has already admitted the opposite of this, viz. that rhetoric may be abused, and that the rhetorician may act unjustly. How is the inconsistency to be explained?
The fallacy of this argument is twofold; for in the first place, a man may know justice and not be just--here is the old confusion of the arts and the virtues;--nor can any teacher be expected to counteract wholly the bent of natural character; and secondly, a man may have a degree of justice, but not sufficient to prevent him from ever doing wrong. Polus is naturally exasperated at the sophism, which he is unable to detect; of course, he says, the rhetorician, like every one else, will admit that he knows justice (how can he
