“Thoreau's careful observations and devastating conclusions have rippled into time, becoming stronger as the weaknesses Thoreau noted have become more pronounced… Events that seem to be completely unrelated to his stay at Walden Pond have been influenced by it, including the national park system, the British labor movement, the creation of India, the civil rights movement, the hippie revolution, the environmental movement, and the wilderness movement. Today, Thoreau's words are quoted with feeling by liberals, socialists, anarchists, libertarians, and conservatives alike.”
