As part of the torture, O’Brien tells Winston that;
‘ No one who has once gone astray is ever spared…even if we chose to let you live out the natural term of your life… you would never escape from us. What happens to you here is for ever.”
“… Never again will you be capable of ordinary human feeling. Everything will be dead inside you. Never again will you be capable of love, or friendship, or joy of living, or laughter, or curiosity, or courage, or integrity. You will be hollow. We shall squeeze you empty, and then we shall fill you with ourselves.’
A heavy apparatus was pushed into place behind his head. O’Brien had sat down beside the bed, so that his face was almost on a level with Winston’s then ordered the machine be cranked to three thousand.
Winston braced for pain but O’Brien said; “This time it will not hurt, keep your eyes fixed on mine.”
Winston does as told and it seemed there had been an explosion. There was a blinding flash of light. Winston was not hurt.
He felt something had happened inside his head. As his eyes regained their focus he remembered who he was, and where he was, and recognized the face that was gazing into his own; but somewhere or other there was a large patch of emptiness, as though a piece had been taken out of his brain.
