An Aristotelian response to Galileo

A PhD thesis written at the Institute for the History and Philosophy of Science and Technology of the University of Toronto. The Supervisors were Prof. Stillman Drake and the Father. James A. Weisheipl. Fabri contended that Galileo had not done physics when he produced his law of falling bodies, because he had not considered causes. Fabri analyses falling body motion and several violent motion using the medieval theory of impetus that Jean Buridan had proposed in 1350 and was the standard theory of motion.
