Walden is a timeless reflection on simplicity, nature, and individual freedom. Written by Henry David Thoreau after two years of living in a cabin by Walden Pond, the book invites readers to consider what it means to live deliberately — with purpose and in harmony with the natural world. Blending memoir, philosophy, and keen observations of daily life, Walden challenges materialism and conformity, encouraging the reader to seek a deeper, more authentic existence. It remains one of the most influential works in American literature and a cornerstone of environmental thought.
