1984

Nobody heard what Big Brother was saying.
It was merely a few words of encouragement, the sort of words that are uttered in the din of battle, not distinguishable individually but restoring confidence by the fact of being spoken.
Then the face of Big Brother faded away again, and instead the three slogans of the Party stood out in bold capitals:

WAR IS PEACE

FREEDOM IS SLAVERY

IGNORANCE IS STRENGTH
