  What of the Biological Criterion?  On an application of that view, some past action is mine for purposes of accountability just in case I am biologically continuous with its agent.  But this again seems neither necessary nor sufficient for ownership.  Were my cerebrum transplanted into another's biological organism, such that that person were now fully psychologically continuous with me, it seems that ownership of my actions would have been transferred as well, such that my cerebrum inheritor now is eligible for accountability for my actions, despite his not being biologically continuous with me.  Furthermore, were immoral Johann to enter a fugue state, yielding a biological successor (call him Sebastian) who was nevertheless completely psychologically discontinuous with Johann, it would be hard to believe Sebastian could continue to be the owner of Johann's actions, despite their biological continuity (D. Shoemaker 2011).
