 According to this new principle, if the waters were too treacherous for a rescue, Luke is blameless for his failure. (He may still be responsible for failing to try, or for failing to call for help.) Similarly, Emily is responsible for not cheating only if she could have done so. If, due to a fear of being caught, she was unable to cheat, or if the means to cheat were simply unavailable to her, she could not be credited for her omission, at least not on that occasion. PAP-omissions is here treated as its own stand-alone principle, though there is some metaphysics behind such an assumption (Clarke 2012; S. Bernstein 2015). The present question is whether it can survive the demise of PAP.
