"Today, great men are no longer necessary. Modern propaganda instruments can transform any fraud into a hero, any mediocre personality into an all-comprehending genius. Propaganda actually transforms through its collective efforts any average, if not stupid, leader, like Hitler and Stalin, into a great man. The leaders become symbols of an organized, collective, and really intelligent will to maintain given social institutions. Outside of Russia, Trotsky was soon reduced to the master of a small sect of professional revolutionists and their providers. He was ‘the Old Man,’ the indisputable authority of an artificial growth upon the political scene, destined to end in absurdity."
