How does the tone in the first half of the book belie or contradict the second half of the book ?

While the
environment surroundingin the first half of the book is grim, he holds on to the hope that a
rebellion is possible and finds encouragement whenintroduces him to a supposed dissident
underground fighting for change. Winston also finds love throughand experiences an old-fashioned
domestic life in the room over Mr. Charrington's shop. Winston and Julia find a haven in nature
as well. While they assume they are doomed, they can't help but hope that somehow they can keep
the tiny world they have created for themselves aliveat least for one more day.

In the second half of the book, all these hopes are shattered, just as Winston's coral
paperweight is shattered by the Thought Police at the end of part 2. In part 3, we no longer
encounter any comforting domestic spaces. The geography of the Ministry of Love is completely
dehumanizing: windowless, alway brightly lit, always stark. O'Brien, through starvation,
beatings, and torture, works to stomp any vestige of hope out of Winston's mind. While a thin
thread of optimism, largely through Winston's thoughts, animates part one, the second part of
the book (specifically part 3) has a tone that is relentlessly
pessimistic.
