Yeah so...transcendentalism is an American literary, political, and philosophical movement of the early nineteenth century, centered around Ralph Waldo Emerson.Stimulated by English and German Romanticism, the Biblical criticism of Herder and Schleiermacher, and the skepticism of Hume, the transcendentalists operated with the sense that a new era was at hand. They were critics of their contemporary society.
