Walden .

Walden (/ˈwɔːldən/; first published in 1854 as Walden; or, Life in the Woods) is a book by American transcendentalist writer Henry David Thoreau.

The work is part personal declaration of independence, social experiment, voyage of spiritual discovery, satire, and—to some degree—a manual for self-reliance.
