Occasionalism is the theory that nothing in real life ever caused anything else. God determined everything that each thing would do when he created the world. So, when one pool ball hits another and the second moves, the first pool ball does not cause the second to move because the second ball was already programmed to move that way on its own. Occasionalism holds that everything that seems to interact is like two clocks side by side with one a fraction of a second set ahead of the other. When the faster clock’s handles move, it only looks like it’s causing the slower clock’s handles to move.
