The reason for the slow progress of the world seems to lie in a single fact. Every man is born under the yoke, and grows up beneath the oppressions of his age. He can only get a vision of the unselfish forces in the world by appealing to them, and every appeal is a call to arms. If he fights he must fight, not one man, but a conspiracy. He is always at war with a civilization. On his side is proverbial philosophy, a galaxy of invisible saints and sages, and the half-developed consciousness and professions of everybody. Against him is the world, and every selfish passion in his own heart.
