George J. Stack traces the sources of ideas and theories that have long been considered the exclusive province of Friedrich Nietzsche to the surprisingly radical writings of the American essayist and poet, Ralph Waldo Emerson. Nietzsche and Emerson makes us see Emerson’s writings in a new, more intensified light and presents a new perspective on Nietzsche’s philosophy. Stack traces how the rich theoretical ideas and literary images of Emerson entered directly into the existential dimension of Nietzsche’s thought and hence into the stream of what has been considered a distinctively European intellectual movement.
