[Side-note: He pursues the investigation of this problem by a series of questions.] First, the Eleate states the opinion which perplexes him, and which he is anxious either to refute or to explain away. (Unfortunately, we have no statement of the opinion, nor of the grounds on which it was held, from those who actually held it.) Non-Ens, or Nothing, is not the name of any existing thing, or of any Something. But every one who speaks must speak something: therefore if you try to speak of Non-Ens, you are trying to speak nothing--which is equivalent to not speaking at all.[34] Moreover, to every Something, you can add something farther: but to Non-Ens, or Nothing, you cannot add any thing. (Non-Entis nulla sunt prædicata.) Now Number is something, or included among the Entia: you cannot therefore apply number, either singular or plural, to Non-Ens: and inasmuch as every thing conceived or described must be either one or many, it is impossible either to conceive or describe Non-Ens. You cannot speak of it without falling into a contradiction.[35] [Footnote 34: Plato, Sophist. p. 237 E. The Eleate here recites this opinion, not as his own but as entertained by others, and as one which he did not clearly see through: in Republic (v. p. 478 B-C) we find Sokrates advancing a similar doctrine as his own. So in the Kratylus, where this same topic is brought under discussion (pp. 429 D, 430 A), Kratylus is represented as contending that false propositions were impossible: that propositions, improperly called false, were in reality combinations of sounds without any meaning, like the strokes on a bell.] [Footnote 35: Plato, Sophist. p. 238-239.] [Side-note: The Sophist will reject our definition and escape, by affirming that to speak falsely is impossible. He will require us to make out a rational theory, explaining Non-Ens.]
