At the bidding of a Peter the Hermit, millions of men hurled themselves against the East; the words of a hallucinated enthusiast such as Mahomet created a force capable of triumphing over the Graeco-Roman word; an obscure monk like Luther batched Europe in blood. The voice of a Galileo or a Newton will never have the least echo among the masses. The inventors of genius hasten the march of civilization. The fanatics and the hallucinated create history - Gustave Le Bon
