Abstract
These substances have been considered in recent times, as in traditional interpretation, to be identical with the immobile Movers of the Physics. Both Physics and Metaphysics refer to the same separate substances. On the other hand, the immobile Movers of the Physics have been identified with the immanent souls of the Heavens, and so sharply distinguished from the separate substances of the Metaphysics. Then in the opposite extreme, the Movers of the Metaphysics have been completely identified with the celestial souls. Or again, the first only of the Movers has been declared separate, and the others identified with the different sphere-souls, among which is the first Mover of the Physics. In still another interpretation the first Mover alone is separate, but the other immobile Movers are held to be the divine thoughts, identical with the first Mover. Even the first Mover has been interpreted as a thought in the mind of some other Being, as merely an ideal or standard of goodness which does not imply--though it need not exclude--any corresponding existent reality in the Aristotelian universe.
