A booklet written by cyberneticist Heinz von Foerster was tucked amid Kurt’s archives, a document Kurt concluded was worth retaining. Entitled “On Constructing a Reality,” the twelve-page excerpt from a von Foerster address of 1973 puts forth the following postulate: “The Environment As We Perceive It Is Our Invention.” Von Foerster then goes on to make his case in support of this postulate. Heinz’ inscription to ”Walter and friends” refers to Walter (Clifford) Barney and Kurt von Meier. The booklet, in its entirety, is reproduced here.
