Henry David Thoreau
Walden (1854) by Henry David Thoreau is a reflective work based on the two years Thoreau spent living simply in a small cabin near Walden Pond. Through observations of nature and philosophical essays, he argues for self-reliance, simplicity, and spiritual growth, criticizing materialism and social conformity. The book presents nature as a source of moral insight and urges individuals to live deliberately, in harmony with the natural world and their inner values.
