Socrates, having got Gorgias to promise that he would answer briefly, proceeds to ask him about what rhetoric is employed, and of what it is the science. Gorgias says, “of words,” but Socrates shews, that other arts, in various degrees, make use of words, and that some, such as arithmetic and geometry, are altogether conversant with words; he therefore requests him to distinguish between these arts and rhetoric, and to explain about what particular thing these words are employed. Gorgias confidently answers, about “the greatest of all human concerns and the best.” But the physician, the teacher of gymnastics, the money-getter, in short all men, would say that the end which their own art aims at is the best; what then is this good which you say is the greatest good to men? Gorgias answers, that it is the power of persuading by words. But Socrates objects that other arts do the same, for that every one who teaches any thing persuades what he teaches; you must therefore say of what kind of persuasion, and on what subject rhetoric is the art. It is that which is produced in courts of justice, and other public assemblies, and relates to matters that are just and unjust. But here again Socrates makes Gorgias admit, that there are two kinds of persuasion, one that produces belief without knowledge, the other that produces knowledge; which of these two then does rhetoric produce? doubtless the former. But supposing the question is about the choice of physicians or shipwrights, or the building of walls, or the construction of ports or docks, will a rhetorician be consulted, or a person skilled in these several matters? Here Gorgias answers that on these and all other subjects a rhetorician will speak more persuasively than any other artist whatever: but it is his duty to use his art justly; though if he uses it unjustly, he and not his teacher is to blame.

Socrates, here, perceiving an inconsistency in Gorgias’ statement, after deprecating his being offended at the course the discussion might take, asks whether by saying that a rhetorician can speak more persuasively to the multitude on any art, than a person skilled in that art, he does not mean the ignorant by the multitude; and, that being admitted, whether it does not follow that one who is ignorant will be more capable of persuading the ignorant, than one who possesses knowledge? Gorgias allows this to be the case. Is the case, then, the same with respect to what is just and unjust, base and honourable, good and evil? Can a rhetorician persuade the multitude on these subjects, himself being ignorant of them, or must he know them before he learns rhetoric, or will the teacher of rhetoric instruct him in these? Gorgias professes that if a pupil does not know these things he would learn them from him. But surely he who has learnt carpentering is a carpenter, music a musician, medicine a physician; does it not follow then, that he who has learnt justice, must be just, and wish to do just actions? Gorgias admits this too: and yet he had just now allowed that a rhetorician might make an unjust use of his art, and said, that in that case, the teacher ought not to be blamed, but the person who acts unjustly ought to be punished.

At this point Polus takes up the discussion, and having elected to ask questions, instead of answering them, begins by asking Socrates what kind of art he considers rhetoric to be. Socrates answers that he does not think it is any art at all, but a kind of skill, employed for procuring gratification and pleasure: in other words, a species of flattery, of which there are many divisions. Polus asks what division it is. “Rhetoric, in my opinion,” says Socrates, “is a semblance of a division of the political art,” and as such is base. This answer, however, is not intelligible either to Gorgias or Polus; at the request of the former, therefore, Socrates explains himself more clearly.

Footnote 48:
§ 38-43.
-----
As there are two kinds of subject matter, he says, namely, soul and body, so there are two arts, that which relates to the soul is political; the other, relating to the body, he is not able to describe by one name, but there are two divisions of it, gymnastics and medicine. In the political art legislation corresponds to gymnastics, and the judicial art to medicine. But flattery, perceiving that these four take the best possible care of the soul and body respectively, has divided itself fourfold, and feigns itself to be what it pretends, not really caring for what is best, but seducing ignorance by means of pleasure. Thus cookery puts on the garb of medicine, and pretends that it knows the aliment best for the body; and again, personal decoration feigns itself to be gymnastics. Then, he adds, what personal decoration is to gymnastics, that is sophistry to legislation, and what cookery is to medicine, that is rhetoric to justice; and so being proximate to each other, sophists and rhetoricians are confounded with legislators and judges.

Are good rhetoricians, then, asks Polus, to be esteemed as vile flatterers in cities? Socrates replies that they appear to him to be of no estimation at all. But have they not the greatest power in cities? Not, if to have power is a good to him who possesses it. For what is it to have power? is it to do what one wishes, or what appears to one to be best? Polus admits that it is not good for a person devoid of understanding to do what appears to him to be best. He must therefore prove that rhetoricians possess understanding, otherwise, since to have power is a good, they cannot do what they wish. Polus, however, is unable to distinguish between doing what one wishes and doing what appears to be best, and therefore agrees to change positions with Socrates, and to answer instead of asking questions.

Footnote 50:
§ 48-50.
-----
Socrates, then, asks, do men wish what they do for the sake of the thing itself, or for some other end? for instance, do men take medicine because they wish to take it, or in order to health? Again, do men incur the perils of the sea because they wish to be in peril, or for the sake of riches? Clearly the latter, in both and all similar cases. Now some things, such as wisdom, health, and riches, are good, but their contraries evil; but whatever we do, we do for the sake of that which is good. So that if we kill or banish a person, if it is good to do so, we wish it, and do what we wish; but if it is really evil, though it appears to us to be good, we do not what we wish. Polus sees the force of Socrates’ argument, and can only object to it that Socrates himself would like to do what he pleased, and would envy another whom he saw slaying, or spoiling, or imprisoning whom he pleased. But Socrates resolutely denies this, and insists that if he must necessarily either act unjustly or suffer unjustly, he should choose the latter; for that it is better to suffer than to commit injustice.
