Aristotle, marble portrait bust, Roman copy of a Greek original (c. 325 bc); in the Museo Nazionale Romano, Rome, Italy.
This is for all who love to explore Aristotle's cosmology and his understanding of the Divine. The Prime Mover is above all other movers.
Excerpt:
In On The Heavens, Aristotle describes ether as the nearest element to the divine due to its perfect and eternal natural motion. Unlike the rectilinear motion of the sublunar elements, the natural motion of ether is circular.
Circular motion is continuous and eternal because a circle, unlike a line, has neither a beginning nor an end. Hence, everything in the supralunary region is eternal, changeless, ungenerated, and imperishable. For all these reasons, Aristotle considered the supralunary region more perfect than the sublunar domain.
The question yet to be answered is what causes the motion of the supralunary region? Given that every movement needs a mover and the Aristotelian cosmos is spatially finite, the series of movers-moved cannot indefinitely extend. As a result, all the series of motion must start with a first mover that is itself unmoved. The Prime Mover is the divine, metaphysical, and immaterial unmoved mover that is the original source of motion in the entire cosmos.
Aristotle argues, however, that the intricate motion of the celestial spheres cannot all be explained by the movement of the sphere of the fixed stars. Hence, in Metaphysics, he proposes that, in addition to the Prime Mover, there are multiple unmoved movers that cause each motion in the supralunary region that the motion of the fixed stars doesn’t account for. As Botteri and Casazza explain in The Astronomical System of Aristotle, these unmoved movers are finite in number, each associated with a celestial sphere. Like the Prime Mover, the unmoved movers are divine, metaphysical, and immaterial. However, they are subordinate to the Prime Mover because they are not responsible for the motion of the entire cosmos, but only partially responsible for the motion of the celestial spheres.
