"Walden Two"'s title is a direct reference to Henry David Thoreau's book "Walden". In the novel, the Walden Two Community is mentioned as having the benefits of living in a place like Thoreau's Walden, but "with company". It is, as the book says, 'Walden for two'—meaning a place for achieving personal self-actualization, but within a vibrant community, rather than in a place of solitude. Originally, Skinner indicated that he wanted to title it "The Sun is but a Morning Star", a quote of the last sentence of Thoreau's "Walden", but the publishers suggested the current title as an alternative.
