Transcendentalism was essentially a religious movement that emerged from Unitarianism in the middle decades of the 19th century. Rev. Barry Andrews views the Transcendentalists—Ralph Waldo Emerson, Henry David Thoreau, and Margaret Fuller among them—as living voices whose writing is addressed as much today as it was in their time to spiritual seekers such as ourselves. In Transcendentalism, he believes we will discover a uniquely and authentically Unitarian Universalist form of spirituality.
