There is another aspect under which some of the dialogues of Plato may be more truly viewed:—they are dramatic sketches of an argument. We have found that in the Lysis, Charmides, Laches, Protagoras, Meno, we arrived at no conclusion—the different sides of the argument were personified in the different speakers; but the victory was not distinctly attributed to any of them, nor the truth wholly the property of any. And in the Cratylus we have no reason to assume that Socrates is either wholly right or wholly wrong, or that Plato, though he evidently inclines to him, had any other aim than that of personifying, in the characters of Hermogenes, Socrates, and Cratylus, the three theories of language which are respectively maintained by them. The two subordinate persons of the dialogue, Hermogenes and Cratylus, are at the opposite poles of the argument. But after a while the disciple of the Sophist and the follower of Heracleitus are found to be not so far removed from one another as at first sight appeared; and both show an inclination to accept the third view which Socrates interposes between them. First, Hermogenes, the poor brother of the rich Callias, expounds the doctrine that names are conventional; like the names of slaves, they may be given and altered at pleasure. This is one of those principles which, whether applied to society or language, explains everything and nothing. For in all things there is an element of convention; but the admission of this does not help us to understand the rational ground or basis in human nature on which the convention proceeds. Socrates first of all intimates to Hermogenes that his view of language is only a part of a sophistical whole, and ultimately tends to abolish the distinction between truth and falsehood. Hermogenes is very ready to throw aside the sophistical tenet, and listens with a sort of half admiration, half belief, to the speculations of Socrates.
