The Absolute Cause of Things Happening in Physical Reality

Realists believe that there are two kinds existence in reality, physical things and abstract things. In physics, the abstract things can cause stuff to happen. This doesn't commit us to any kind of woo or supernatural force or spirituality. The way in which physical things are arranged is not haphazard, it's not chaotic. There's something more to it, and even more profound, the abstractThings can cause things to occur. They really are the proximate and indeed ultimate cause of many kinds of events that happen in the universe.
