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?
