“We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.”

American transcendentalist writer and naturalist of the mid-19th century, Thoreau is best known for his philosophical essays and his two-year experiment in simple living at Walden Pond. His work bridges practical observation of nature with deep reflection on individualism, civil disobedience, and the importance of living deliberately.
