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.
Heinrich Cornelius AgrippaOnly for you, children of doctrine and learning, have we written this work. Examine this book, ponder the meaning we have dispersed in various places and gathered again; what we have concealed in one place we have disclosed in another, that it may be understood by your wisdom.
Heinrich Cornelius Agrippa
