You 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 OrwellIf he were allowed contact with foreigners he would discover that they are creatures similar to himself and that most of what he has been told about them is lies. The sealed world in which he lives would be broken, and the fear, hatred and self-righteousness on which his morale depends might evaporate.
