No matter how finely you subdivide time and space, each tiny division contains infinity.

I began to suspect there must be flaws in my sense of reality.It seemed to my dim sense of confusion that things often blended one into another, and the Law of Excluded Middle merely opened up a void wherein anything was possible.
