Context

“and it is hard to find a reason why any one should doubt that he likewise fills immensity. His infinite being is certainly as boundless one way as another; and methinks it ascribes a little too much to matter to say, where there is no body, there is nothing. 4. Why Men more easily admit infinite Duration than infinite Expansion.
