resemblances, and to escape from such a deception when employed against ourselves. We see therefore that even in rhetoric an element of truth is required. For if we do not know the truth, we can neither make the gradual departures from truth by which men are most easily deceived, nor guard ourselves against deception.
Socrates then proposes that they shall use the two speeches as illustrations of the art of rhetoric; first distinguishing between the debatable and undisputed class of subjects. In the debatable class there ought to be a definition of all disputed matters. But there was no such definition in the speech of Lysias; nor is there any order or connection in his words any more than in a nursery rhyme. With this he compares the regular divisions of the other speech, which was his own (and yet not his own, for the local deities must have inspired him). Although only a playful composition, it will be found to embody two principles: first, that of synthesis or the comprehension of parts in a whole; secondly, analysis, or the resolution of the whole into parts. These are the processes of division and generalization which are so dear to the dialectician, that king of men. They are effected by dialectic, and not by rhetoric, of which the remains are but scanty after order and arrangement have been subtracted. There is nothing left but a heap of 'ologies' and other technical terms invented by Polus, Theodorus, Evenus, Tisias, Gorgias, and others, who have rules for everything, and who teach how to be short or long at pleasure. Prodicus showed his good sense when he said that there was a better thing than either to be short or long, which was to be of convenient length.
Still, notwithstanding the absurdities of Polus and others, rhetoric has great power in public assemblies. This power, however, is not given by any technical rules, but is the gift of genius. The real art is always being confused by rhetoricians with the preliminaries of the art. The perfection of oratory is like the perfection of anything else; natural power must be aided by art. But the art is not that which is taught in the schools of
