More quotes by George Orwell, 1984

"He who controls the past controls the future. He who controls the present controls the past."
"Confession is not betrayal. What you say or do doesn't matter; only feelings matter. If they could make me stop loving you-that would be the real betrayal."
"Reality exists in the human mind, and nowhere else."
"For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable – what then?"
"The best books... are those that tell you what you know already."
