Nature Theater of Oklahoma talks with Nikolaus Müller-Schöll, author, professor, and theater scientist at Goethe-Universität in Frankfurt about the role of discourse and critical thinking and theory in the performing arts.  What is the role of the artist in this discourse?  Can we offer any insight into our work?  And, conversely, do those who write about theater (even 18th century theater) also need to sit in the audience or be engaged somehow in current practice?
