In this paper I consider a recent objection to compatibilism—the manipulation argument. This argument relies on two plausible principles: a manipulation principle that holds that manipulation precludes free will and moral responsibility, and a ‘no difference principle’ that holds that manipulation is relevantly similar to determinism. To respond to this argument, the compatibilist must reject either the manipulation principle or the ‘no difference principle.’ I argue that rejecting the manipulation principle offers the compatibilist the most compelling response to the manipulation argument. Incompatibilists claim that this strategy is implausible because it requires that some victims of manipulation are free and responsible. I aim to show that this consequence is not as implausible as it might initially appear.
