  However, on this account, given that sameness of memory is a necessary condition for sameness of person, if a person at time tn does not remember (episodically) an event that occurred at time t1, then the person at time tn cannot be identical with any person who was witness or agent to the event at time t1. If the general cannot remember being beaten at school, he cannot be identical with the boy who was beaten. Thus, the Memory Theory is committed to mutually incompatible theses: that the General is identical with the boy and that he is not.
