More quotes by George Orwell, 1984

"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?"
"He who controls the past controls the future. He who controls the present controls the past."
"He was a lonely ghost uttering a truth that nobody would ever hear."
"The best books... are those that tell you what you know already."
"He was conscious of nothing except the blankness of the page in front of him, the itching of the skin above his ankle, the blaring of the music, and a slight booziness caused by the gin."
