What is the fundamental process that governs social or physical existence? This is a very old sounding question in that the Greeks wondered which of the four elements predominated in the makeup of the world. Was it air, fire, earth or wind? And, later on in the ancient world, there was a search for the greatest good, the most perfect emotion. Was it stoicism or cynicism or pleasure? Far from being put away, this same question crops up in modern thought. When I was a graduate student, people discussed whether Hobbes had found out the true secret of social life, that the fundamental force was violence; that was what guaranteed social order and so economic forces and other social forces paled in comparison with the ability of violence to dominate the scene. Hobbes had discovered not invented a solution, never mind that Hobbes thought reason rather than violence governed human interaction or that violence is useful under certain conditions but that under other circumstances money and prestige are more important motivators. People die for their country for a reason and arms merchants are motivated by greed. Violence is useful only when there is anarchy in the air or when there is foreign invasion or there is a crime of passion.
