  It is important to notice that while Reid uses the term ‘evidence,’ when describing the role that memory plays in first-personal knowledge of one’s own past, memory is not used by persons to justify judgments or beliefs about their own pasts. In other words, people do not remember events and then conclude from having remembered them, that it was they who were witness to the events. Rather, memory itself represents one’s presence at the event remembered. According to Reid, a memory consists in a conception of an event and a belief, about the event conceived, that it happened to me, where the pronoun is indexed to the person who is represented in the memory as agent or witness. In other words, memory consists in part in a judgment that represents one’s presence at the event. Any further judgment, justified by memory, to the effect that I was the person who was there would be superfluous—memory already testifies to my having been there. This is why Reid calls the evidence of memory immediate: first-personal statements about one’s own past are memory statements, not statements made on the basis of memory.
