| PART 8: THE
There are nine subjects that cover everything that exists, namely: GOD, Angel, Heaven, Man, Imagination, Senses, Vegetation, Elements, and Artificial instruments. And because of the diversity of these subjects, the principles of this art are diversified. In this way, through whatever is more like or unlike the subjects, conclusions can be drawn from the principles and rules. For in the same way as a crystal can take on various colorings, so can the principles be varied as they are juxtaposed to various subjects.
