For as to the attempt to escape this consequence by saying that if the world has boundaries (in time and space) then the infinite emptiness would have to determine the existence of things as to their magnitude, this consists in thinking surrepjtiously of who knows what intelligible world in place of a world of sense, and, instead of a first beginning (an existence before which a time of non existence precedes) one thinks of an existence in general that presupposes no other condition in the world, rather than the boundary of extension one thinks of the limits of the world whole, and thus one gets time and space out of the way.
