I am very much aware of my own double self... The well-known one is very under control; everything is planned and very secure. The unknown one can be very unpleasant. I think this side is responsible for all the creative work — he is in touch with the child. He is not rational, he is impulsive and extremely emotional. Perhaps it is not even a "he," but a "she."

As quoted in "Ingmar Bergman: Summing Up A Life In Film" by Michiko Kakutani in The New York Times Magazine (26 June 1983).
