"All debate about the truth or falsity of a totalitarian dictator's prediction is as weird as arguing with a potential murderer about whether his future victim is dead or alive-since by killing the person in question the murderer can promptly provide proof of the correctness of his statement. The only valid argument under such conditions is to promptly rescue the person whose death is predicted. Before mass leaders seize the power to fit reality to their lies, their propaganda is marked by its extreme contempt for facts as such, for in their opinion fact depends entirely on the power of the man who can fabricate it. The assertion that the Moscow subway is the only one in the world is a lie only so long as the Bolsheviks have not the power to destroy it," - Hannah Arendt, Origins of Totalitarianism.
