Quote 16
Very likely the confessions had been rewritten and rewritten until the original facts and dates no longer had the smallest significance. The past not only changed, but changed continuously. What most afflicted him with the sense of nightmare was that he had never clearly understood why the huge imposture was undertaken. The immediate advantages of falsifying the past were obvious, but the ultimate motive was mysterious. He took up his pen again and wrote:
I understand HOW: I do not understand WHY. (1.7.24-25, Winston)
Winston does not understand the ultimate motive behind the Party’s control and falsification of records.
Quote 17
He seemed to breathe again the warm stuffy odor of the basement kitchen, an odor compounded of bugs and dirty clothes and villainous cheap scent, but nevertheless alluring, because no woman of the Party ever used scent, or could be imagined as doing so. Only the proles used scent. In his mind the smell of it was inextricably mixed up with fornication. (1.6.7)
Winston is so sexually repressed that he finds the cheap scent of prostitutes alluring.
Quote 18
When he had gone with that woman it had been his first lapse in two years or thereabouts. Consorting with prostitutes was forbidden, of course, but it was one of those rules that you could occasionally nerve yourself to break. It was dangerous, but it was not a life-and-death matter. To be caught with a prostitute might mean five years in a forced-labor camp: not more, if you had committed no other offence. (1.6.8)
Sexually repressed to the extreme, Winston employs prostitutes to quell his urges.
