That is clear.
Then the one, which is not, partakes, as would appear, of greatness and smallness and equality?
Clearly.
Further, it must surely in a sort partake of being?
How so?
It must be so, for if not, then we should not speak the truth in saying that the one is not. But if we speak the truth, clearly we must say what is. Am I not right?
Yes.
And since we affirm that we speak truly, we must also affirm that we say what is?
Certainly.
Then, as would appear, the one, when it is not, is; for if it were not to be when it is not, but (Or, 'to remit something of existence in relation to not-being.') were to relinquish something of being, so as to become not-being, it would at once be.
Quite true.
Then the one which is not, if it is to maintain itself, must have the being of not-being as the bond of not-being, just as being must have as a bond the not-being of not-being in order to perfect its own being; for the truest assertion of the being of being and of the not-being of not-being is when being partakes of the being of being, and not of the being of not-being--that is, the perfection of being; and when not-being does not partake of the not-being of not-being but of the being of not-being--that is the perfection of not-being.
Most true.
Since then what is partakes of not-being, and what is not of being, must not the one also partake of being in order not to be?
Certainly.
Then the one, if it is not, clearly has being?
Clearly.
And has not-being also, if it is not?
Of course.
But can anything which is in a certain state not be in that state without changing?
Impossible.
Then everything which is and is not in a certain state, implies change?
Certainly.
And change is motion--we may say that?
Yes, motion.
And the one has been proved both to be and not to be?
Yes.
And therefore is and is not in the same state?
