In Geneva lived Jean-Jacques Rousseau. He too was a rebel, mighty in war. Voltaire was keener, wittier, deeper, greater. Rousseau was more fiery, emotional, passionate. Both were really warriors in the same great cause. From their different places, three miles apart, both sent forth their thunderbolts to wake a sleeping world. When the world awakened and shook itself, churches, thrones, institutions, laws, and customs were buried in the wreck. Some charged the wreck to Voltaire, some to Rousseau.

Voltaire (1916)
