Henry David Thoreau went to Walden Pond to "live deliberately" — and his mother did his laundry. The most famous act of self-reliance in American literature took place on land owned by Emerson, a twenty-minute walk from town, and Thoreau went home regularly for meals. None of this diminishes Walden, but the gap between the mythology of radical independence and the reality of a man who never fully left his social network is more interesting than either version alone.

This episode traces Thoreau from his pencil-factory family through the Walden experiment, the night in jail that produced "Civil Disobedience," and the naturalist writing that anticipated environmentalism by a century.
