DIADUMENUS. First, this is altogether absurd and against sense, to say that is which is not, and things which are not are. But above all, that is most absurd which they say of the universe. For, putting round about the circumference of the world an infinite vacuum, they say that the universe is neither a body nor bodiless. It follows then from this that the universe has no being, since with them body only has a being. Since therefore it is the part of that which has a being both to do and suffer, and the universe has no being, it follows that the universe will neither do nor suffer. Neither will it be in a place; for that which takes up place is a body, and the universe is not a body, therefore the universe is nowhere. And since that only rests which continues in one and the same place, the universe rests not, because it takes not up place. Neither yet is it moved, for what is moved must have a place and space to move in. Moreover, what is moved either moves itself, or suffers motion from another. Now, that which is moved by itself has some bents and inclinations proceeding from its gravity or levity; and gravity and levity are either certain habits or faculties or differences of bodies. But the universe is not a body. It follows then of necessity, that the universe is neither heavy nor light, and consequently, that it has not in itself any principle of motion. Nor yet will the universe be moved by any other; for there is nothing else besides the universe. Thus are they necessitated to say as they do, that the universe neither rests nor is moved. Lastly, since according to their opinion it must not be said that the universe is a body, and yet the heaven, the earth, animals, plants, men, and stones are bodies, it follows that that which is no body will have bodies for its parts, and things which have existence will be parts of that which has no existence, and that which is not heavy will have parts that are heavy, and what is not light will have parts that are light;—than which there cannot be any dreams imagined more repugnant to the common conceptions.
