Why, in 1984, does O'Brien call Winston the "last man"?

In 's
, calls"the last man" in reference to Winston's rebellious
spirit, which O'Brien feels must be subdued. In calling Winston the last man, O'Brien is
pointing out that he is an isolated individual in the sea of people who have accepted the Party
or given up trying to fight. Winston is a rare person in that he actually sees himself as an
individual rather than as an unthinking part of the Party. O'Brien encourages Winston to accept
the futility of resisting the Party. Winston believes that the spirit of humanity will
eventually overthrow the Party, as masses of people will one day fight back. O'Brien's response
is that Winston, by being the last man, is alone in this fight for
humanity.
