STRANGER: If not-being has no part in the proposition, then all things must be true; but if not-being has a part, then false opinion and false speech are possible, for to think or to say what is not—is falsehood, which thus arises in the region of thought and in speech. THEAETETUS: That is quite true. STRANGER: And where there is falsehood surely there must be deceit. THEAETETUS: Yes. STRANGER: And if there is deceit, then all things must be full of idols and images and fancies. THEAETETUS: To be sure. STRANGER: Into that region the Sophist, as we said, made his escape, and, when he had got there, denied the very possibility of falsehood; no one, he argued, either conceived or uttered falsehood, inasmuch as not-being did not in any way partake of being. THEAETETUS: True. STRANGER: And now, not-being has been shown to partake of being, and therefore he will not continue fighting in this direction, but he will probably say that some ideas partake of not-being, and some not, and that language and opinion are of the non-partaking class; and he will still fight to the death against the existence of the image-making and phantastic art, in which we have placed him, because, as he will say, opinion and language do not partake of not-being, and unless this participation exists, there can be no such thing as falsehood. And, with the view of meeting this evasion, we must begin by enquiring into the nature of language, opinion, and imagination, in order that when we find them we may find also that they have communion with not- being, and, having made out the connexion of them, may thus prove that falsehood exists; and therein we will imprison the Sophist, if he deserves it, or, if not, we will let him go again and look for him in another class. THEAETETUS: Certainly, Stranger, there appears to be truth in what was said about the Sophist at first, that he was of a class not easily caught, for he seems to have abundance of defences, which he throws up, and which must every one of them be stormed before we can reach the man himself. And even now, we have with difficulty got through his first defence, which is the not- being of not-being, and lo! here is another; for we have still to show that falsehood exists in the sphere of language and opinion, and there will be another and another line of defence without end. STRANGER: Any one, Theaetetus, who is able to advance even a little 791
