 Fischer and Ravizza’s theory of freedom and responsibility has shifted the focus of much recent debate to questions of sourcehood. Moreover, one might argue that this theory is a clear improvement over classical compatibilism with respect to handling cases of phobia. By focusing on mechanisms, Fischer and Ravizza can argue that our agoraphobic Luke is not morally responsible for deciding to refrain from going outside because the mechanism that issues in this action—namely his agoraphobia—is not moderately reasons-responsive. There is no world with the same laws of nature as our own, this mechanism operates, and yet it reacts to a sufficient reason to go outside. No matter what reasons there are for Luke to go outside, when acting on this mechanism, he will always refrain from going outside (cf. Fischer 1987, 74).
