"The medieval theologians would not be surprised at a prerequisite of a degree in physics for a degree in theology. In their time, the highest degree in philosophy—which included the most advanced knowledge of physics of the day—was a prerequisite before a student was permitted to begin study for a degree in theology...Kenny has shown the Aquinas' Five Ways—his five proofs of God's existence—are absolutely dependent on Aristotelian physics...Aquinas...was one of the leading scholars of Aristotelian physics...and...was primarily responsible for...[its] general acceptance throughout Europe. We could call Aquinas a great physicist as well as a great theologian, for, although Aristotelian physics was wrong, it was an essential precursor of modern physics."
