 Another objection to the cause-law principle comes from the state of contemporary physics. According to quantum mechanics, it is not simply difficult or impossible for us to state such laws for quantum phenomena. Rather, quantum theory appears to entail that determinism fails to obtain at the level of microparticles. What the theory and the behavior of such particles tells us is that causation, at least at the level of micro phenomena, is indeterministic. And this indeterminism is claimed to be inconsistent with the requirement of strict laws. This objection to the cause-law principle, then, is that philosophy should never dictate to science on empirical matters. Observation of the world tells us that strict laws are impossible in this domain even while causation is present, in direct contradiction of the cause-law principle.
