Party is remaking humankind in its own image. In fact, as he describes it, the Party is planning
to dehumanize the human race. He says that the Party is working on engineering test-tube babies,
and is planning on eradicating all emotions except fear, rage, triumph, and self
abasement.

O'Brien continues on that train of thought in the quote above. He
says that the pleasures that are currently part of what make people human, such as curiosity,
will be completely destroyed. He says that what will remain--the one pleasure--will be a kind of
power that exults in triumphing over another person. All that will be left to enjoy will be the
thrill of smashing your boot on some helpless person's face.

O'Brien is
trying to convince Winston that the Party is all powerful and always will be. He is
communicating his idea that Winston's faith in the human spirit and such positive attributes as
love for another human being, kindness, and compassion is misplaced. O'Brien has a very grim
vision of the future.
