 Notice that, because Frankfurt examples challenge the incompatibilists’ demand for regulative control, they also challenge an agent-based reasons-responsive theory (Fischer &amp; Ravizza 1998, pp. 34–41). Imagine that the benevolent demon Jerry Garcia wants Frank to play the banjo at the relevant time. Jerry would much prefer that Frank play the banjo on his own. But worried that Frank might elect not to play the banjo, Jerry covertly arranges things so as to manipulate Frank if the need arises. If Frank should show any indication that he will not play the banjo, Jerry will manipulate Frank so that Frank will play the banjo. Hence, when Frank does play the banjo uninfluenced by Jerry’s possible intervention, he does so of his own free will. But he has neither regulative control, nor does he seem to be reasons-responsive, with respect to his banjo playing. Due to Jerry’s presence, he cannot but play the banjo even if Jimi Hendrix were to ask Frank to play his guitar.
