The God of St. Thomas and Dante is a God Who loves, the god of Aristotle is a god who does not refuse to be loved; the love that moves the heavens and the stars in Aristotle is the love of the heavens and the stars for god, but the love that moves them in St. Thomas and Dante is the love of God for the world; between these two motive causes there is all the difference between an efficient cause on the one hand, and a final cause on the other.
