Causal Closure is referred to as the ‘Completeness of Physics’. For physics to be causally closed, all physical events must be due to physical causes. It is especially important when considering dualist theories of mind. It seems intuitively problematic to strip mental events of their causal power. In modern times, it has been pointed out that science is based on removing the subject from investigations, and by seeking objectivity, creating a susceptibility to the subject-object problem.
