From
Wikiquote:
Michael Moore declares these lines in his film Fahrenheit 9/11 as something "Orwell once wrote". They are nearly identical to a block of narration in the 1984 Richard Burton/John Hurt movie version of 1984
when Winston (Hurt) is reading Goldstein's book. All of the lines are
excerpts from various parts of Goldstein's book in part 2, chapter 9 of
the novel with some paraphrasing.
I have made a detailed comparison between the "Orwell once wrote" quote,
1984 movie (Burton/Hurt version), and the novel
1984.
