Henry David Thoreau defined modern environmentalism and nonviolent resistance. The author of Walden and Civil Disobedience, his words still resonate.

Henry David Thoreau helped define modern environmentalism and nonviolent resistance, yet his life has been obscured by myth. The author of Walden and Civil Disobedience, he was brilliant but flawed, idealistic but opinionated. A writer, scientist and activist, his words resonate urgently with today’s challenges as humanity looks for ways to live in harmony with nature—and each other.
