The magician and the epistemological optimist and pessimist

Just last night I watched Ingmar Bergman's film called "The Magician". In this movie a traveling troupe known as Volger's Magnetic Heath Theatre is invited to the city of Stolkholm to privately perform for a medical officer and his commitee. The medical officer is an epistemoligcal optimist because he believes everything can be explained through science. His friend, however, is an epistemological pessimist, and believes that somethings in life remain inexplicable and can never be known. At the beggining of the film, the doctor and his friend tell the magician why they had sent for him. They reveal they had made a bet to see if magic or "the unknown" really does exist. The doctor, of course does not think it does, while the friend believes otherwise. In the end, though some of the Magician's tricks are de-mystified, he still managed to stupify the audience. Because there is no real conclusion, both the doctor and the friend's opinion are neither backed nor dis-proven. Ingmar Bergman leaves us to decide for ourselves what conclusions to make in regards to "magic".
