In the next stage of his “education” Winston is told plainly by O’Brien that the Party wants power for its own sake. There are no lies now, the Party is not promising Utopia. The aim is to dehumanize the human race, to obliterate every emotion and instinct except loyalty to the Party. And Winston, as much as anyone else would come to accept this not just as inevitable, but desirable.
Winston puts up a feeble resistance even now. He says that finally, in the last instance the human spirit would overthrow the regime O’Brien was describing. O’Brien mockingly asks him if he considers himself a man. When he says that he does, he is told to look at himself in a mirror and he sees a rotting, emaciated stinking body. That, O’Brien tells him is the last remnant of humanity. It cannot survive. The symbol of the future, O’Brien says is a boot permanently stamping on the human face. He then tells Winston that they have broken his mind as badly as they have shattered his body and asks him if there is any degradation or humiliation that he has not been reduced to. As his last stand Winston claims that he has despite everything not betrayed Julia. O’Brien immediately understands what he means by this – he has revealed all of their secrets, but in the sense of not ceasing to love her, Winston had not betrayed Julia. That, then was the final stage he had to be reduced to.
