Santo Tomás de Aquino y el Motor inmóvil / Aquinas and the Unmoved Mover

Abstract

Alexander of Aphrodisias understood the Aristotle ́s Unmoved Mover as efficient cause only to the extent that it is the final cause of heaven, which by moving strives to imitate the divine rest. Aquinas seems to agree with him. However his interpretation is original and philosophically more satisfactory: God is the efficient cause of the world, not only as creator, but also as it ́s ruler. In this way God is also the final cause.
