Causation requires (at least the possibility of) contingent counterfactual dependence between events at different times. Contingent counterfactual dependence requires logically irreversible laws connecting those events. But logically irreversible laws only give you contingent counterfactual dependence in one direction. Thus, contingent counterfactual dependence between events is temporally asymmetric. Our actual laws are logically irreversible. Thus, causation is temporally asymmetric.
