Dialogues of Plato - MobileReference [882]
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
