[I know, all I do these days is quote books, but this passage has been on my mind, especially in relation to Mr Schlect's discussions of the nature of history.]
from chapter 1, as Winston is beginning his first diary entry:
For whom, it suddenly occurred to him to wonder, was he writing this diary? For the future, for the unborn. [...] For the first time the magnitude of what he had undertaken came home to him. How could you communicate with the future? It was of its nature impossible. Either the future would resemble the present, in which case it would not listen to him: or it would be different from it, and his predicament would be meaningless.
