Winston Smith

For whom, it suddenly occurred to him to wonder, was he writing this diary?
For the future, for the unborn. His mind hovered for a moment round the
doubtful date on the page, and then fetched up with a bump against the
Newspeak word DOUBLETHINK. 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.
