I believe that when one has a theory about something, one is already dead. I don't have time to think about theories. One should create emotions, not create under rules. To work with rules is to work with one's experience, is to fall into routine. I know a man named Kracauer who wrote a book called From Caligari to Hitler. His theory is absolutely false. He used all his arguments to prove a false theory. I therefore feel forced to dissuade today's youth from believing in a book that is full of idiocies. I told him. He was very angry. [Laughs] You know I have a language, I simply use it and I can prove anything. But it isn't necessary for my truth. A theory is nothing for an artist, it serves only for people who are already dead.
