"Anyone who is of a thoughtful, philisophical cast of mind will occasionaly be struck by the appearance of certain organizing principles of history. The forms these principles seem to take inevitably depends upon one's specific obsession. For a mornachist, history is a struggle of classes of economic civil war. An agriculturalist sees the dynamic of populations, land, and availability of food; a philosopher might speak of the will to power or the will to sythesis; a theologian of the will of God."
