If a person at time tn does not episodically remember an event at time t1, then the person at time tn cannot be identical with any person who was witness or agent to that event at t1.

subscript notation (tn, t1)(as used in this logical statement)
A shorthand way of labeling different points in time: t1 means an earlier time, and tn means a later time, where 'n' just represents 'some number'—it's like saying 'then' versus 'now.'
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 Gener
