"That was mere foreplay. Where they have burned books, they will end up burning people." Henrich Heine (1821)

From Wikipedia:
"In 1834, 99 years before Adolf Hitler and the Nazi Party seized power in Germany, Heine wrote in his work The History of Religion and Philosophy in Germany:
Christianity - and that is its greatest merit - has somewhat mitigated that brutal Germanic love of war, but it could not destroy it. Should that subduing talisman, the cross, be shattered, the frenzied madness of the ancient warriors, that insane Berserk rage of which Nordic bards have spoken and sung so often, will once more burst into flame. This talisman is fragile, and the day will come when it will collapse miserably. Then the ancient stony gods will rise from the forgotten debris and rub the dust of a thousand years from their eyes, and finally Thor with his giant hammer will jump up and smash the Gothic cathedrals....Do not smile at my advice -- the advice of a dreamer who warns you against Kantians, Fichteans, and philosophers of nature. Do not smile at the visionary who anticipates the same revolution in the realm of the visible as has taken place in the spiritual. Thought precedes action as lightning precedes thunder. German thunder is of true Germanic character; it is not very nimble, but rumbles along ponderously. Yet, it will come and when you hear a crashing such as never before has been heard in the world's history, then you know that the German thunderbolt has fallen at last. At that uproar the eagles of the air will drop dead, and lions in the remotest deserts of Africa will hide in their royal dens. A play will be performed in Germany which will make the French Revolution look like an innocent idyll."
