19. Spirits capable of motion.
There is no reason why it should be thought strange, that I make mobility belong to
spirit; for having no other idea of motion, but change of distance with other beings that are considered as at rest;
and finding that spirits, as well as bodies, cannot operate but where they are; and that spirits do operate at several
times in several places, I cannot but attribute change of place to all finite spirits: (for of the Infinite Spirit I speak
not here). For my soul, being a real being as well as my body, is certainly as capable of changing distance with
any other body, or being, as body itself; and so is capable of motion. And if a mathematician can consider a
certain distance, or a change of that distance between two points, one may certainly conceive a distance, and a
change of distance, between two spirits; and so conceive their motion, their approach or removal, one from
another.
