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, as I was saying, let us first of all obtain a conception of language and opinion, in order that we may have clearer grounds for determining, whether not-being has any concern with them, or whether they are both always true, and neither of them ever false. THEAETETUS: True. STRANGER: Then, now, let us speak of names, as before we were speaking of ideas and letters; for that is the direction in which the answer may be expected. THEAETETUS: And what is the question at issue about names? STRANGER: The question at issue is whether all names may be connected with one another, or none, or only some of them. THEAETETUS: Clearly the last is true. STRANGER: I understand you to say that words which have a meaning when in sequence may be connected, but that words which have no meaning when in sequence cannot be connected? THEAETETUS: What are you saying?
