35. Is universal space infinite or limited?

"Infinite. Suppose the existence of boundaries, what would there be beyond them? This consideration confounds human reason; and nevertheless your reason itself tells you that it cannot be otherwise. It is thus with the idea of infinity, under whatever aspect you consider it. The idea of infinity cannot be comprehended in your narrow sphere."

If we imagine a limit to space, no matter how far off our thought may place this limit, our reason tells us that there must still be something beyond it; and so on, step by step, until we arrive at the idea of infinity; for the "something beyond," the existence of which is recognised by our thought as a necessity, were it only an absolute void, would still be space.

36. Does an absolute void exist in any part of space?

"No; there is no void. What appears like a void to you is occupied by matter in a state in which it escapes the action of your senses and of your instruments."
