In 1845 Henry David Thoreau, one of the principal New England Transcendentalists, left the town for the country. Beside the lake of Walden, he built himself a log cabin and returned to nature, to observe and reflect – while surviving on eight dollars a year. From this experience emerged one of the great classics of American literature, a deeply personal reaction against the commercialism and materialism that he saw as the main impulses of mid-nineteenth-century America.
