"[T]he German scene was transformed by the entry of Hitler: never before had a man so malignant attained such power, nor a nation shown so little revulsion from evil. Crude and hysterical, full of virulent hatreds and envy, he powerfully appealed to the Germans, and set about doing their work in Europe... Hitler had shrewd skill, but no wisdom; with him there was no appealing to reason or even to rational interests—which men like Chamberlain were slow to grasp. Nor was there in him a conscious control of his own moves; hence he appeared incalculable and chaotic."
