 Another reason PAP is important is that it intersects with the philosophy and practice of law. Even if moral and legal responsibility do not coincide, there is a region of overlap (Duff 2009; Brink &amp; Nelkin 2013) where PAP and its attendant literature can inform legal reasoning, especially when it aims at the just punishment of wrongdoers. A necessary condition of criminal responsibility is that the conduct included a voluntary act (Sinnott-Armstrong 2012), one that the accused had a “reasonable opportunity to avoid” (Kelly 2017). If Mark was sleepwalking or hypnotized when he broke into Ken’s house, this could be excused, both morally and legally, on the grounds that in his condition, Mark could not have done otherwise. If, due to delusion, an accused murderer could not avoid forming the intention to kill his victim—and acting accordingly—this also could be exculpating.
