The Aristotelian Approach to Change

Aristotle says that for change to occur, you need a certain causal principle. To make sense of why there's any change at all whatsoever, you need to get back to something that is an unchanged changer or an unmoved mover. For the Aristotelians, many will argue that that's going to be God. And it's an a temporal entity because for Aristotle, time itself is just a measure of change.
