Natural Magick is taken to be nothing else, but the chief power of all the natural Sciences; which therefore they call the top and perfection of Natural Philosophy, and which is indeed the active part of the same; which by the assistance of natural forces and faculties, through their mutual & opportune application, performs those things that are above Human Reason.
