Past Memories
1984
Memories.
what i think this is saying, is that everything in the past controls what happens in the future and with that being the case, the inner party ( government ) is making such strict laws about memories of the past so that know one knows what had happened back then and they dont want you to think about anything from the past.
Quotes
Winston's memories of the past is fuzzy because of the Party's control and elimination of records in the past and present.
Even though Winston's has evidence of the party's lies in his memory, he also accepts that the unreliability of his mind will soon expunge that evidence as well.
