 the divine science must enter into this science, since God is the principle of being simpliciter, not of one being as distinguished from another being. And the division which gives the principle of being must be the divine science, since these concepts are not proper to physics but are higher than physics in generality. So this science is higher than the science of nature, and after the science of nature, and for this reason it should be called the science of metaphysics [lit. the science of what is after nature].
