" What is a fanatic but a man whose faith is impregnable to doubt? It is the faith that moves mountains, the faith that accomplishes. Revolutions are not made by Hamlets. The traditional “great” man, the “big personality” of current conception, may give to the world new thoughts, noble vision, inspiration. But the man that “sees every side” cannot lead, cannot control. He is too conscious of the fallibility of all theories, even of thought itself, to be a fighter in any cause. "

― Alexander Berkman , The Bolshevik Myth
