THEAETETUS: Most assuredly.

STRANGER: And as we cannot admit that a man speaks and says nothing, he who says 'not-being' does not speak at all.

THEAETETUS: The difficulty of the argument can no further go.

STRANGER: Not yet, my friend, is the time for such a word; for there still remains of all perplexities the first and greatest, touching the very foundation of the matter.

THEAETETUS: What do you mean? Do not be afraid to speak.

STRANGER: To that which is, may be attributed some other thing which is?

THEAETETUS: Certainly.

STRANGER: But can anything which is, be attributed to that which is not?

THEAETETUS: Impossible.

STRANGER: And all number is to be reckoned among things which are?

THEAETETUS: Yes, surely number, if anything, has a real existence.

STRANGER: Then we must not attempt to attribute to not-being number either in the singular or plural?

THEAETETUS: The argument implies that we should be wrong in doing so.

STRANGER: But how can a man either express in words or even conceive in thought things which are not or a thing which is not without number?

THEAETETUS: How indeed?

STRANGER: When we speak of things which are not, are we not attributing plurality to not-being?

THEAETETUS: Certainly.

STRANGER: But, on the other hand, when we say 'what is not,' do we not attribute unity?

THEAETETUS: Manifestly.

STRANGER: Nevertheless, we maintain that you may not and ought not to attribute being to not-being?

THEAETETUS: Most true.

STRANGER: Do you see, then, that not-being in itself can neither be spoken, uttered, or thought, but that it is unthinkable, unutterable, unspeakable, indescribable?

THEAETETUS: Quite true.

STRANGER: But, if so, I was wrong in telling you just now that the difficulty which was coming is the greatest of all.

THEAETETUS: What! is there a greater still behind?

STRANGER: Well, I am surprised, after what has been said already, that you do not see the difficulty in which he who would refute the notion of not-being is involved. For he is compelled to contradict himself as soon as he makes the attempt.

THEAETETUS: What do you mean? Speak more clearly.

STRANGER: Do not expect clearness from me. For I, who maintain that not-being has no part either in the one or many, just now spoke and am still speaking of not-being as one; for I say 'not-being.' Do you understand?

THEAETETUS: Yes.

STRANGER: And a little while ago I said that not-being is unutterable, unspeakable, indescribable: do you follow?
