The one shred of hope left
The ending of 1984 is very bleak, with Winston being conditioned into the perfect Party member, completely loyal to Oceania, hateful toward Oceania's enemies, and fully accepting that the memories of his past are fake. With Winston and Julia having had their rebellion quite literally beaten out of them, there seems to be no hope of overthrowing the Party. However, a shred of this hope can still be found in the most unlikely of places: the book's appendix, The Principles of Newspeak. The appendix is written in past tense, with phrases like "... Newspeak would have finally superseded Oldspeak" and "Its vocabulary was so constructed", implying that Newspeak, and the Party by extension, no longer exists in the present day. Perhaps an underground rebellion formed despite the Party's attempts to stamp it out, or maybe the Party fell apart on its own.
