“He is a farmer. He lives a simple life. He's pretty well educated. He's read Shakespeare, he's read Wordsworth. His wife is a teacher. They have a very comfortable life. They don't have anything to complain about in eighteen forty-nine. This is a key point. They did not have anything that would cause them distress. His expectations were perfectly comfortable expectations of an average family, a farming family in America. The Gold Rush changed that. Suddenly he wanted more. Suddenly he wasn't satisfied.”
