O’Brien knew everything. A thousand times better than Winston, he knew what the world was really like, in what degradation the mass of human beings lived and by what lies and barbarities the Party kept them there. He had understood it all, weighed it all, and it made no difference: all was justified by the ultimate purpose. What can you do, thought Winston, against the lunatic who is more intelligent than yourself, who gives your arguments a fair hearing and then simply persists in his lunacy?
