" They looked like the meeting of a provincial town council, and were preparing the greatest revolution in human history. They were at that time a handful of men of an entirely new species: militant philosophers. They were as familiar with the prisons in the towns of Europe as commercial travellers with the hotels. They dreamed of power with the object of abolishing power; of ruling over the people to wean them from the habit of being ruled. All their thoughts became deeds and all their dreams were fulfilled. Where were they? Their brains, which had changed the course of the world, had each received a charge of lead. Some in the forehead, some in the back of the neck. Only two or three of them were left over, scattered throughout the world, worn out. "
