 The rhetorician is a maker of beliefs in the souls of his auditors (455a3–4). And without that skill—here Gorgias begins to wax at length and eloquently—other arts (such as medicine) cannot do their work effectively (456b ff.). Rhetoric is a comprehensive art. But Gorgias offers a crucial qualification that turns out to contribute to his downfall: rhetoric should not be used against any and everybody, any more than skill in boxing should be. Although the rhetorician teaches others to use the skill justly, it is always possible for the student to misuse it. This is followed by another damaging admission: the rhetorician knows what justice, injustice, and other moral qualities are, and teaches them to the student if the student is ignorant of them (460a). It would follow that, in Socrates’ language, the true rhetorician is a philosopher; and in fact that is a position Socrates takes in the Phaedrus. But Gorgias is not a philosopher and does not in fact know—cannot give an account of—the moral qualities in question. So his art is all about appearing, in the eyes of the ignorant, to know about these topics, and then persuading them as is expedient (cf. 459d-e). But this is not something Gorgias wishes to admit; indeed, he allows himself to agree that since the rhetorician knows what justice is, he must be a just man and therefore acts justly (460b-c). He is caught in a contradiction: he claimed that a student who had acquired the art of rhetoric could use it unjustly, but now claims that the rhetorician could not commit injustice.
