Institutio Oratoria

Now it is only rhetoric as practised in their own day that is condemned by Plato or Socrates, for he speaks of it as

the manner in which you engage in public affairs

[*](500 c.) : rhetoric in itself he regards as a genuine and honourable thing, and consequently the controversy with Gorgias ends with the words,

The rhetorician therefore must be just and the just man desirous to do what is just.

[*](460 c.)

To this Gorgias makes no reply, but the argument is taken up by Polus, a hot-headed and headstrong young fellow, and it is to him that Socrates makes his remarks about

shadows

and

forms of flattery.

Then Callicles, [*](508 c.) who is even more hot-headed, intervenes, but is reduced to the conclusion that

he who would truly be a rhetorician ought to be just and possess a knowledge of justice.

It is clear therefore that Plato does not regard rhetoric as an evil, but holds that true rhetoric is impossible for any save a just and good man. In the Phaedrus [*](261 A-273 E.)
