Part 11
THEAETETUS: Quite true.
STRANGER: Yet they surely both partake of the same and of the other?
THEAETETUS: Yes.
STRANGER: Then we must not assert that motion, any more than rest, is either the same or the other.
THEAETETUS: No; we must not.
STRANGER: But are we to conceive that being and the same are identical?
THEAETETUS: Possibly.
STRANGER: But if they are identical, then again in saying that motion and rest have being, we should also be saying that they are the same.
THEAETETUS: Which surely cannot be.
STRANGER: Then being and the same cannot be one.
THEAETETUS: Scarcely.
STRANGER: Then we may suppose the same to be a fourth class, which is now to be added to the three others.
THEAETETUS: Quite true.
STRANGER: And shall we call the other a fifth class? Or should we consider being and other to be two names of the same class?
THEAETETUS: Very likely.
STRANGER: But you would agree, if I am not mistaken, that existences are relative as well as absolute?
THEAETETUS: Certainly.
STRANGER: And the other is always relative to other?
THEAETETUS: True.
STRANGER: But this would not be the case unless being and the other entirely differed; for, if the other, like being, were absolute as well as relative, then there would have been a kind of other which was not other than other. And now we find that what is other must of necessity be what it is in relation to some other.
THEAETETUS: That is the true state of the case.
STRANGER: Then we must admit the other as the fifth of our selected classes.
THEAETETUS: Yes.
STRANGER: And the fifth class pervades all classes, for they all differ from one another, not by reason of their own nature, but because they partake of the idea of the other.
THEAETETUS: Quite true.
STRANGER: Then let us now put the case with reference to each of the five.
THEAETETUS: How?
STRANGER: First there is motion, which we affirm to be absolutely 'other' than rest: what else can we say?
THEAETETUS: It is so.
STRANGER: And therefore is not rest.
THEAETETUS: Certainly not.
STRANGER: And yet is, because partaking of being.
THEAETETUS: True.
STRANGER: Again, motion is other than the same?
THEAETETUS: Just so.
STRANGER: And is therefore not the same.
THEAETETUS: It is not.
STRANGER: Yet, surely, motion is the same, because all things partake of the same.
THEAETETUS: Very true.
STRANGER: Then we must admit, and not object to say, that motion is the same and is not the same, for we do not apply the terms 'same' and 'not the same,' in the same sense; but we call it the 'same,' in relation to itself, because partaking of the same; and not the same, because having communion with the other, it is thereby severed from the same, and has become not that but other, and is therefore rightly spoken of as 'not the same.'
THEAETETUS: To be sure.
STRANGER: And if absolute motion in any point of view partook of rest, there would be no absurdity in calling motion stationary.
THEAETETUS: Quite right,--that is, on the supposition that some classes mingle with one another, and others not.
STRANGER: That such a communion of kinds is according to nature, we had already proved before we arrived at this part of our discussion.
THEAETETUS: Certainly.
STRANGER: Let us proceed, then. May we not say that motion is other than the other, having been also proved by us to be other than the same and other than rest?
THEAETETUS: That is certain.
STRANGER: Then, according to this view, motion is other and also not other?
THEAETETUS: True.
STRANGER: What is the next step? Shall we say that motion is other than the three and not other than the fourth,--for we agreed that there are five classes about and in the sphere of which we proposed to make enquiry?
THEAETETUS: Surely we cannot admit that the number is less than it appeared to be just now.
STRANGER: Then we may without fear contend that motion is other than being?
THEAETETUS: Without the least fear.
STRANGER: The plain result is that motion, since it partakes of being, really is and also is not?
THEAETETUS: Nothing can be plainer.
STRANGER: Then not-being necessarily exists in the case of motion and of every class; for the nature of the other entering into them all, makes each of them other than being, and so non-existent; and therefore of all of them, in like manner, we may truly say that they are not; and again, inasmuch as they partake of being, that they are and are existent.
THEAETETUS: So we may assume.
STRANGER: Every class, then, has plurality of being and infinity of not-being.
THEAETETUS: So we must infer.
STRANGER: And being itself may be said to be other than the other kinds.
THEAETETUS: Certainly.
STRANGER: Then we may infer that being is not, in respect of as many other things as there are; for not-being these it is itself one, and is not the other things, which are infinite in number.
THEAETETUS: That is not far from the truth.
STRANGER: And we must not quarrel with this result, since it is of the nature of classes to have communion with one another; and if any one denies our present statement [viz., that being is not, etc.], let him first argue with our former conclusion [i.e., respecting the communion of ideas], and then he may proceed to argue with what follows.
THEAETETUS: Nothing can be fairer.
STRANGER: Let me ask you to consider a further question.
THEAETETUS: What question?
STRANGER: When we speak of not-being, we speak, I suppose, not of something opposed to being, but only different.
THEAETETUS: What do you mean?
STRANGER: When we speak of something as not great, does the expression seem to you to imply what is little any more than what is equal?
THEAETETUS: Certainly not.
STRANGER: The negative particles, ou and me, when prefixed to words, do not imply opposition, but only difference from the words, or more correctly from the things represented by the words, which follow them.
THEAETETUS: Quite true.
STRANGER: There is another point to be considered, if you do not object.
THEAETETUS: What is it?
STRANGER: The nature of the other appears to me to be divided into fractions like knowledge.
THEAETETUS: How so?
STRANGER: Knowledge, like the other, is one; and yet the various parts of knowledge have each of them their own particular name, and hence there are many arts and kinds of knowledge.
THEAETETUS: Quite true.
STRANGER: And is not the case the same with the parts of the other, which is also one?
THEAETETUS: Very likely; but will you tell me how?
STRANGER: There is some part of the other which is opposed to the beautiful?
THEAETETUS: There is.
STRANGER: Shall we say that this has or has not a name?
THEAETETUS: It has; for whatever we call not-beautiful is other than the beautiful, not than something else.
STRANGER: And now tell me another thing.
THEAETETUS: What?
STRANGER: Is the not-beautiful anything but this--an existence parted off from a certain kind of existence, and again from another point of view opposed to an existing something?
THEAETETUS: True.
STRANGER: Then the not-beautiful turns out to be the opposition of being to being?
THEAETETUS: Very true.
STRANGER: But upon this view, is the beautiful a more real and the not-beautiful a less real existence?
THEAETETUS: Not at all.
STRANGER: And the not-great may be said to exist, equally with the great?
THEAETETUS: Yes.
STRANGER: And, in the same way, the just must be placed in the same category with the not-just--the one cannot be said to have any more existence than the other.
THEAETETUS: True.
STRANGER: The same may be said of other things; seeing that the nature of the other has a real existence, the parts of this nature must equally be supposed to exist.
THEAETETUS: Of course.
STRANGER: Then, as would appear, the opposition of a part of the other, and of a part of being, to one another, is, if I may venture to say so, as truly essence as being itself, and implies not the opposite of being, but only what is other than being.
THEAETETUS: Beyond question.
STRANGER: What then shall we call it?
THEAETETUS: Clearly, not-being; and this is the very nature for which the Sophist compelled us to search.
STRANGER: And has not this, as you were saying, as real an existence as any other class? May I not say with confidence that not-being has an assured existence, and a nature of its own? Just as the great was found to be great and the beautiful beautiful, and the not-great not-great, and the not-beautiful not-beautiful, in the same manner not-being has been found to be and is not-being, and is to be reckoned one among the many classes of being. Do you, Theaetetus, still feel any doubt of this?
THEAETETUS: None whatever.
STRANGER: Do you observe that our scepticism has carried us beyond the range of Parmenides' prohibition?
THEAETETUS: In what?
STRANGER: We have advanced to a further point, and shown him more than he forbad us to investigate.
THEAETETUS: How is that?
STRANGER: Why, because he says--
'Not-being never is, and do thou keep thy thoughts from this way of enquiry.'
THEAETETUS: Yes, he says so.
STRANGER: Whereas, we have not only proved that things which are not are, but we have shown what form of being not-being is; for we have shown that the nature of the other is, and is distributed over all things in their relations to one another, and whatever part of the other is contrasted with being, this is precisely what we have ventured to call not-being.
THEAETETUS: And surely, Stranger, we were quite right.
STRANGER: Let not any one say, then, that while affirming the opposition of not-being to being, we still assert the being of not-being; for as to whether there is an opposite of being, to that enquiry we have long said good-bye--it may or may not be, and may or may not be capable of definition. But as touching our present account of not-being, let a man either convince us of error, or, so long as he cannot, he too must say, as we are saying, that there is a communion of classes, and that being, and difference or other, traverse all things and mutually interpenetrate, so that the other partakes of being, and by reason of this participation is, and yet is not that of which it partakes, but other, and being other than being, it is clearly a necessity that not-being should be. And again, being, through partaking of the other, becomes a class other than the remaining classes, and being other than all of them, is not each one of them, and is not all the rest, so that undoubtedly there are thousands upon thousands of cases in which being is not, and all other things, whether regarded individually or collectively, in many respects are, and in many respects are not.
THEAETETUS: True.
STRANGER: And he who is sceptical of this contradiction, must think how he can find something better to say; or if he sees a puzzle, and his pleasure is to drag words this way and that, the argument will prove to him, that he is not making a worthy use of his faculties; for there is no charm in such puzzles, and there is no difficulty in detecting them; but we can tell him of something else the pursuit of which is noble and also difficult.
THEAETETUS: What is it?
STRANGER: A thing of which I have already spoken;--letting alone these puzzles as involving no difficulty, he should be able to follow and criticize in detail every argument, and when a man says that the same is in a manner other, or that other is the same, to understand and refute him from his own point of view, and in the same respect in which he asserts either of these affections. But to show that somehow and in some sense the same is other, or the other same, or the great small, or the like unlike; and to delight in always bringing forward such contradictions, is no real refutation, but is clearly the new-born babe of some one who is only beginning to approach the problem of being.
THEAETETUS: To be sure.
STRANGER: For certainly, my friend, the attempt to separate all existences from one another is a barbarism and utterly unworthy of an educated or philosophical mind.
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, 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 assent; 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 assent 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.'
THEAETETUS: That also is a sentence which will be admitted by every one to speak of me, and to apply to me.
STRANGER: We agreed that every sentence must necessarily have a certain quality.
THEAETETUS: Yes.
STRANGER: And what is the quality of each of these two sentences?
THEAETETUS: The one, as I imagine, is false, and the other true.
STRANGER: The true says what is true about you?
THEAETETUS: Yes.
STRANGER: And the false says what is other than true?
THEAETETUS: Yes.
STRANGER: And therefore speaks of things which are not as if they were?
THEAETETUS: True.
STRANGER: And say that things are real of you which are not; for, as we were saying, in regard to each thing or person, there is much that is and much that is not.
THEAETETUS: Quite true.
STRANGER: The second of the two sentences which related to you was first of all an example of the shortest form consistent with our definition.
THEAETETUS: Yes, this was implied in recent admission.
STRANGER: And, in the second place, it related to a subject?
THEAETETUS: Yes.
STRANGER: Who must be you, and can be nobody else?
THEAETETUS: Unquestionably.
STRANGER: And it would be no sentence at all if there were no subject, for, as we proved, a sentence which has no subject is impossible.
THEAETETUS: Quite true.
STRANGER: When other, then, is asserted of you as the same, and not-being as being, such a combination of nouns and verbs is really and truly false discourse.
THEAETETUS: Most true.
STRANGER: And therefore thought, opinion, and imagination are now proved to exist in our minds both as true and false.
THEAETETUS: How so?
STRANGER: You will know better if you first gain a knowledge of what they are, and in what they severally differ from one another.
THEAETETUS: Give me the knowledge which you would wish me to gain.
STRANGER: Are not thought and speech the same, with this exception, that what is called thought is the unuttered conversation of the soul with herself?
THEAETETUS: Quite true.
STRANGER: But the stream of thought which flows through the lips and is audible is called speech?
THEAETETUS: True.
STRANGER: And we know that there exists in speech...
THEAETETUS: What exists?
STRANGER: Affirmation.
THEAETETUS: Yes, we know it.
STRANGER: When the affirmation or denial takes Place in silence and in the mind only, have you any other name by which to call it but opinion?
THEAETETUS: There can be no other name.
STRANGER: And when opinion is presented, not simply, but in some form of sense, would you not call it imagination?
THEAETETUS: Certainly.
STRANGER: And seeing that language is true and false, and that thought is the conversation of the soul with herself, and opinion is the end of thinking, and imagination or phantasy is the union of sense and opinion, the inference is that some of them, since they are akin to language, should have an element of falsehood as well as of truth?
THEAETETUS: Certainly.
