 The because-relationship in question is stronger than counterfactual dependence, because it can be absent even when counterfactual dependence is present, as in the case of divine foreknowledge. (Though you won’t answer the phone tomorrow at 9 am because God foreknew you would do so, your answering it at 9 tomorrow is nevertheless counterfactually dependent on God’s foreknowledge: were God to have believed yesterday that you won’t answer the phone at 9 tomorrow, you wouldn’t answer the phone at 9 tomorrow, and were God to have believed that you will answer at 9, you would answer at 9.) What’s needed is the stronger relationship of explanatory dependence.
