The past is a curious thing. It's with you all the time. I suppose an hour never passes without your thinking of things that happened ten or twenty years ago, and yet most of the time it's got no reality, it's just a set of facts that you've learned, like a lot of stuff in a history book. Then some chance sight or sound or smell, especially smell, sets you going, and the past doesn't merely come back to you, you're actually IN the past. It was like that at this moment.
George OrwellYou believe that reality is something objective, external, existing in its own right. You also believe that the nature of reality is self-evident. When you delude yourself into thinking that you see something, you assume that everyone else sees the same thing as you. But I tell you, Winston, that reality exists in the human mind, and nowhere else. Not in the individual mind, which can make mistakes, and in any case soon perishes: only in the mind of the Paty, which is collective and immortal.
George Orwell
