At the bidding of a Peter the Hermit millions of men hurled themselves against the East; the word of an hallucinated enthusiast such as Mahomet created a force capable of triumphing over the Graeco-Roman world; and obscure monk like Luther bathed Europe in blood. The voice of a Galileo or a Newton will never have the least echo amount the masses. The inventors of genius hasten the march of civilization. The fanatics and the hallucinated create history. - Gustave Le Bon (1841-1931)
