Gorgias
From the encyclopedia of philosophy:
Gorgias’ most famous critic is Plato. In the dialogue Gorgias, Plato (through his mentor Socrates) expresses his contempt for sophistical rhetoric; all rhetoric is “a phantom of a branch of statesmanship (463d)…a kind of flattery…that is contemptible,” because its aim is simply pleasure rather than the welfare of the public.
Nor can rhetoric be considered an art (technĂȘ), since it is irrational (465a). The end result of rhetoric is a cosmetic alteration of language that conceals truth and falsity (465b). Furthermore, rhetoric is “designed to produce conviction, but not educate people, about matters of right or wrong (455a). The character of Gorgias in the dialogue is forced to admit that his “art” deals with opinion (doxa) rather than knowledge (epistemĂȘ); that its intention is to persuade rather than to instruct, and that rhetoric deals with language without regard to content.
Gorgias is portrayed as a man with an ambivalent attitude towards truth, a relativist, who boldly asserts that it does not matter if one truly has knowledge of any given subject, only that he is perceived by others to have knowledge, and that “rhetoric is the only area of expertise you need to learn. You can ignore all the rest and still get the better of the professionals!” (459c).
