That leaves no room for free will

"But the problem is that we seem to live in a universe where every physical event has a physical cause. Furthermore, there is what is known as the ‘causal closure of the physical domain’, meaning that everything within the physical world is caused by physical events and nothing else. Add to this the fact that all our actions involve physical movements. Even private thoughts involve physical brain events. Put these facts together and a surprising conclusion follows: all our actions must be caused entirely by events in the physical world. And because physical causation is deterministic – which means that causes necessitate their effects in some way – that leaves no room for free will."
