Abstract

Frankfurt’s famous counterexample strategy challenges the traditional association between moral responsibility and alternative possibilities. While this strategy remains controversial, it is now widely agreed that an adequate response to it must preserve an agent’s ability to do otherwise, and not the mere possibility, for only then is her alternative possibility sufficiently robust to ground her responsibility. Here, I defend a more stringent requirement for robustness. To have a robust alternative, I argue, the agent must have the right kind of ability, where the right kind is such that it is up to her whether she does otherwise. I argue that this kind of power attribution is epistemically conditioned. While a few writers have defended an epistemic condition for robustness, seeing this condition as a consequence of the relevant power attributions will provide much-needed support and clarification, while also illuminating the kind of ability in which free will consists
