Note 716 — Chapter XII
Reading edition
Footnote 716: (return) "Physics are concerned with things which have a principle of motion in themselves; mathematics speculate on permanent, but not transcendental and self-existent things; and there is another science separate from these two, which treats of that which is immutable and transcendental, if indeed there exists such a substance, as we shall endeavor to show that there does. This transcendental and permanent substance, if it exist at all, must surely be the sphere of the divine--it must be the first and highest principle. Hence it follows that there are three kinds of speculative science--Physics, Mathematics, and Theology."--"Metaphysics," bk. x. ch. vii.
