Some of the treasures in the Archives of von Meier are recordings of the AUM Conference at Esalen in 1973. Until recently, it was believed these recordings had been lost. In attendance were Alan Watts, Ram Dass, Heinz von Foerster, John Lilly, Karl Pribram, Stewart Brand, Kurt von Meier and other notables. In this recording of the opening session, the participants introduce themselves, and then all turn to G. Spencer Brown (pictured above in 1973) and his discussion of Laws of Form, the book that had brought the group together. Brown discusses, among other topics, his personal history, Four Color Theorem, the Order of Unlearning, Entering the Kingdom of Heaven, and the Theory of Types.
