Heinz von Foerster (pictured at left during the AUM Conference), scientist and expert in cybernetics, delivered an engaging talk during the AUM Conference at Esalen in 1973 about the way in which we as individuals form hypotheses about reality, confirm them and then construct descriptions of that reality. He also reviews the function and limitations of our sensory apparatus, and how we know what we know.
Kurt von Meier recorded von Foerster’s talk; his presentation lasts about 30 minutes.
