Hitler appeared, a man with limited intellectual abilities and unfit for any useful work, bursting with envy and bitterness against all whom circumstance and nature had favored over him....In his desperate ambition for power he discovered that his speeches, confused and pervaded with hate as they were, received wild acclaim by those whose situation and orientation resembled his own. He picked up this human flotsam on the streets and in the taverns and organized them around himself. This is the way he launched his political career.
