THEAETETUS: Why so?
STRANGER: The attempt at universal separation is the final annihilation of all reasoning; for only by the union of conceptions with one another do we attain to discourse of reason.
THEAETETUS: True.
STRANGER: And, observe that we were only just in time in making a resistance to such separatists, and compelling them to admit that one thing mingles with another.
THEAETETUS: Why so?
STRANGER: Why, that we might be able to assert discourse to be a kind of being; for if we could not, the worst of all consequences would follow; we should have no philosophy. Moreover, the necessity for determining the nature of discourse presses upon us at this moment; if utterly deprived of it, we could no more hold discourse; and deprived of it we should be if we admitted that there was no admixture of natures at all.
THEAETETUS: Very true. But I do not understand why at this moment we must determine the nature of discourse.
STRANGER: Perhaps you will see more clearly by the help of the following explanation.
THEAETETUS: What explanation?
STRANGER: Not-being has been acknowledged by us to be one among many classes diffused over all being.
THEAETETUS: True.
STRANGER: And thence arises the question, whether not-being mingles with opinion and language.
THEAETETUS: How so?
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 ought to be of good cheer, for what would he who is dispirited at a little progress do, if he were making none at all, or even undergoing a repulse? Such a faint heart, as the proverb says, will never take a city: but now that we have succeeded thus far, the citadel is ours, and what remains is easier.
THEAETETUS: Very true.
STRANGER: Then,
