First published in 1854, Henry David Thoreau"s groundbreaking "Walden" has influenced generations of readers and continues to inspire and inform anyone with an open mind and a love of nature. There is so much wisdom in Walden, it's impossible to digest it all even in a dozen readings. Pithy lines and quotes by Henry David Thoreau tend to the return to the reader over and over again, as life rolls along. A favorite quote from Thoreau states that he would be happy to live in a pine box, three feet by six feet, as long as he could wake up every morning in the middle of nature. When it came to simplicity and sustainability, Henry David Thoreau was years ahead of his time. Walden, along with the journals of Henry David Thoreau, constitute some of the most useful of and timeless of all American literature.
