Part 21

THEAETETUS: Of course not.

STRANGER: It is also plain, that in speaking of something we speak of being, for to speak of an abstract something naked and isolated from all being is impossible.

THEAETETUS: Impossible.

STRANGER: You mean by assenting to imply that he who says something must say some one thing?

THEAETETUS: Yes.

STRANGER: Some in the singular (ti) you would say is the sign of one, some in the dual (tine) of two, some in the plural (tines) of many?

THEAETETUS: Exactly.

STRANGER: Then he who says 'not something' must say absolutely nothing.

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?
