One might think that a period which, in a space of fifty years, uproots, enslaves, or kills seventy million human beings should be condemned out of hand. But its culpability must still be understood... In more ingenuous times, when the tyrant razed cities for his own greater glory, when the slave chained to the conqueror's chariot was dragged through the rejoicing streets, when enemies were thrown to the wild beasts in front of the assembled people, the mind did not reel before such unabashed crimes, and the judgment remained unclouded. But slave camps under the flag of freedom, massacres justified by philanthropy or by a taste for the superhuman, in one sense cripple judgment. On the day when crime dons the apparel of innocence - through a curious transposition peculiar to our times - it is innocence that is called upon to justify itself.
