Kurt and Clifford Barney (his close friend and collaborator) spent years plumbing the depths of G. Spencer Brown's Laws of Form, published in 1969. A subject of creative speculation and deep contemplation, their interest resulted in meetings with Brown and the convening of a symposium at Esalen in 1973, entitled the "AUM Conference". Attendees at the conference included von Meir, Barney and Brown, of course, plus Alan Watts, John Lilly, Gregory Bateson, Ram Dass, Karl Pribram, Claudio Naranjo, Heinz von Foerster, Charles Tart, Douglas Kelly, Ted Guinn, and Steward Brand. A short text by Kurt and Clifford explains their interest in Laws of Form.
