But not of solid body, as I've shown,
Exists the nature of the world, because
In things is intermingled there a void;
Nor is the world yet as the void, nor are,
Moreover, bodies lacking which, percase,
Rising from out the infinite, can fell
With fury-whirlwinds all this sum of things,
Or bring upon them other cataclysm
Of peril strange; and yonder, too, abides
The infinite space and the           abyss--
Whereinto, lo, the ramparts of the world
Can yet be shivered.
