Gustave Le Bon,
The Psychology of Revolution
“ Enthusiasm.—The enthusiasm of the founders of the Revolution equalled that of the apostles of the faith of Mohammed. And it was really a religion that the bourgeois of the first Assembly thought to found. They thought to have destroyed an old world, and to have built a new one upon its ruins. Never did illusion more seductive fire the hearts of men. Equality and fraternity, proclaimed by the new dogmas, were to bring the reign of eternal happiness to all the peoples. Man had broken for ever with a past of barbarity and darkness. ”
