In this course, designed for students and professionals in the stage arts, Rudolf Steiner begins with a fundamental and spiritually-rooted appreciation of human speech and what actually takes place during human communication. Speech is a spiritual activity as well as an art form, lending itself to real interaction with both higher spiritual worlds and the human world of social conversation. Steiner shows that speech is a powerful tool for any serious dramatist in conveying the reality of worlds, whether visible or invisible, to the individual souls in the audience. This is an essential book for anyone involved in speech work, communication arts, and many kinds of therapies.
