Abstract:  A vital presupposition of an influential argument for the incompatibility of divine foreknowledge and libertarian free action is that free action requires alternative possibilities. A recent, noteworthy challenge to this presupposition invokes a “Divine Frankfurt-type example”: God's foreknowledge of one's future actions prevents one from doing otherwise without having any responsibility-undermining effect on one's actions. First, I explain why features of God's omniscience cast doubt on this Frankfurtian response. Second, even if this appraisal is mistaken, I argue that divine foreknowledge is irreconcilable with moral obligation if such foreknowledge eliminates alternatives.
