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? Yes. Thus the one that is not has been shown to have motion also, because it changes from being to not-being? That appears to be true. But surely if it is nowhere among what is, as is the fact, since it is not, it cannot change from one place to another? Impossible. Then it cannot move by changing place? 725
