“Five groups had ruled pre-war Germany: the twenty-odd sovereigns with the Kaiser at their head, the Army officers, the officials, the aristocratic land-owners and the possessors of heavy industry. Amid a people conditioned to obedience, they alone knew what they wanted and were not afraid to take it. An experimental Republic that did not break the political necks of nearly all five groups was, in time, almost bound once more to fall under their rule. Such is the law of the jungle.”
