Motion According to Aquinas and Newton

This article seeks to examine the theological basis of the understanding of motion in the work of Aquinas and Newton. As well as the Aristotelian roots of Aquina's view, attention is also paid to motion understood as a participation in the perfect 'motionless motion' of the emanation of the Son from the Father. This is contrasted with the crucial theological context of Newton's view of motion as expressed in the Principia , namely his Arianism and theological voluntarism. Motion becomes a purely physical and spatial category predicted on violent competition rather than mutual enhancement and the goal of perfection. Meanwhile, it is suggested that Newton has to resort to unmediated divine action within absolute and eternal space in order to describe how a universe in motion might have anything to do with God.
