The heavens would be immovable if the Soul rested, that is, if she remained only in the intelligible world, where everything remains immovable. But because the Soul is in no one determinate place, and because the whole of her is everywhere, the heavens move through the whole of space; and as they cannot go out of themselves, they must move in a circle. HOW OTHER BEINGS MOVE.[314] 2. How do the other beings move? As none of them is the whole, but only a part, consequently, each finds itself situated in a particular place. On the contrary, the heavens are the whole; they constitute the place which excludes nothing, because it is the universe. As to the law according to which men move, each of them, considered in his dependence towards the universe, is a part of all; considered in himself, he is a whole. WHY THE HEAVENS MOVE IN A CIRCLE. Now, if the heavens possess the Soul, wherever they are, what urges them to move in a circle? Surely because the Soul is not exclusively in a determinate place (and the world does not exclusively in one place desire to possess her). Besides, if the power of the Soul revolve around the centre, it is once more evident that the heavens would move in a circle. DIFFERENCE BETWEEN THE CENTRE OF THE SOUL AND THE BODY. Besides, when we speak of the Soul, we must not understand the term "centre" in the same sense as when it is used of the body. For the Soul, the centre is the focus of (the intelligence) whence radiates a second life (that is, the Soul); as to the body, it is a locality (the centre of the world). Since, however, both soul and body need a centre, we are forced to use this word in an analogous meaning which may suit both of them. Speaking strictly, however, a centre can exist only for a spherical body, and the analogy consists in this, that the latter, like the Soul, effects a reflection upon itself. In this case, the Soul moves around the divinity, embraces Him, and clings to Him with all her might; for everything depends from Him. But, as she cannot unite herself to Him, she moves around Him. THE ADDITION OF OUR BODIES INTRODUCES CONFLICTING MOTIONS.
