Author’s note: This essay interrupts the sequence of expository essays on Plato’s Laws to answer an objection that questions the validity of the entire series. Transcendentalism is the name of an intellectual movement that flourished in the United States during the 19th century, especially in New England. Ralph Waldo Emerson and Henry David Thoreau are its leading proponents. Their writings range over a wide range of topics, literary, philosophical, religious, and political. The influence of Plato and Platonism is evident throughout them.
