Working on an essay

About one of the underpinnings of liberty. It concerns the fact that man is a limited creature. Because man is limited, any and all attempts to arrive at "Utopia" will fail. Any political philosophy that relies on the "perfectability" of man will fail. Freedom allows for each one to chart his own course and make his own mistakes. The mistakes of an individual effect only a small segment of society. The mistakes of a flawed, limited human ruler in charge of a large segment of society bring down everyone.
