Someone asked me whether the entries in my diary are true, and when I said that essentially the entries are true, they asked me what did I mean by essentially, to which I replied that even when the entries are not recollections of events that have occurred, they are recollections of how those events would have occurred if they in fact had occurred. Though when this person then asked me how could I be certain that an event that had not occurred would occur the way I imagined it would, I told them I could not be certain, but that nevertheless I was.
