 Suppose first that Pro-R determines Jones’ choice. In that case, it’s no longer clear that Jones is responsible, for he’s been locked into his choice by a prior cause. Certainly PAPs defenders—who tend to be libertarians about free will and moral responsibility—will balk at attributing responsibility to an agent whose actions are causally determined. Lost, then, is the initially powerful appearance that Jones is morally responsible. On the other hand, suppose Pro-R does not determine Jones’ later choice. In that case, Jones could have chosen otherwise, for the sign—the only thing that stays Black’s hand—leaves open that Jones will vote for the Democrat. Jones thus has an alternative, and a robust one at that: this is no mere flicker.
