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?
STRANGER: What I thought that you intended when you gave your a.s.sent; for there are two sorts of intimation of being which are given by the voice.
THEAETETUS: What are they?
STRANGER: One of them is called nouns, and the other verbs.
THEAETETUS: Describe them.
STRANGER: That which denotes action we call a verb.
THEAETETUS: True.
STRANGER: And the other, which is an articulate mark set on those who do the actions, we call a noun.
THEAETETUS: Quite true.
STRANGER: A succession of nouns only is not a sentence, any more than of verbs without nouns.
THEAETETUS: I do not understand you.
STRANGER: I see that when you gave your a.s.sent you had something else in your mind. But what I intended to say was, that a mere succession of nouns or of verbs is not discourse.
THEAETETUS: What do you mean?
STRANGER: I mean that words like "walks," "runs," "sleeps," or any other words which denote action, however many of them you string together, do not make discourse.
THEAETETUS: How can they?
STRANGER: Or, again, when you say "lion," "stag," "horse," or any other words which denote agents--neither in this way of stringing words together do you attain to discourse; for there is no expression of action or inaction, or of the existence of existence or non-existence indicated by the sounds, until verbs are mingled with nouns; then the words fit, and the smallest combination of them forms language, and is the simplest and least form of discourse.
THEAETETUS: Again I ask, What do you mean?
STRANGER: When any one says "A man learns," should you not call this the simplest and least of sentences?
THEAETETUS: Yes.
STRANGER: Yes, for he now arrives at the point of giving an intimation about something which is, or is becoming, or has become, or will be.
And he not only names, but he does something, by connecting verbs with nouns; and therefore we say that he discourses, and to this connexion of words we give the name of discourse.
THEAETETUS: True.
STRANGER: And as there are some things which fit one another, and other things which do not fit, so there are some vocal signs which do, and others which do not, combine and form discourse.
THEAETETUS: Quite true.
STRANGER: There is another small matter.
THEAETETUS: What is it?
STRANGER: A sentence must and cannot help having a subject.
THEAETETUS: True.
STRANGER: And must be of a certain quality.
THEAETETUS: Certainly.
STRANGER: And now let us mind what we are about.
THEAETETUS: We must do so.
STRANGER: I will repeat a sentence to you in which a thing and an action are combined, by the help of a noun and a verb; and you shall tell me of whom the sentence speaks.
THEAETETUS: I will, to the best of my power.
STRANGER: "Theaetetus sits"--not a very long sentence.
THEAETETUS: Not very.
STRANGER: Of whom does the sentence speak, and who is the subject? that is what you have to tell.
THEAETETUS: Of me; I am the subject.
STRANGER: Or this sentence, again--
THEAETETUS: What sentence?
STRANGER: "Theaetetus, with whom I am now speaking, is flying."
