Summary. Walden is an account of the two years during which Henry David Thoreau built his own cabin, raised his own food, and lived a life of simplicity in the woods near Concord, Massachusetts. Thoreau's idea was that one's true self could be lost amid the distractions of ordinary life. Thoreau's attitude toward reform involved his transcendental efforts to live a spiritually meaningful life in nature. As a transcendentalist, Thoreau believed that reality existed only in the spiritual world, and the solution to people's problems was the free development of emotions ("Transcendentalism").
