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.

George Orwell

1984. Part 3, Chapter 2. Winston’s torturer O’Brien articulates Big Brother’s ability to strip Winston of his very humanity.
