We can no longer separate things as we once could: everything tends towards unity; one thing, one action, in one place, at one time. On the other hand, we can no longer unify things as we once could; we are driven to ultimate atoms, each one of which is an individuality. So that we have an infinite multitude of things doing an infinite multitude of actions in infinite time and space; and yet they are not many things, but one thing.
