Von Foerster, H. & Poerksen, B. (2002). Understanding systems: Conversations on epistemology and ethics. New York: Kluwer Academic/Plenum Publishers. Pages 11-63.

Summary

We read the first Chapter of a book that consists of a dialogue between “a physicist and philosopher Heinz von Foerster and journalist Bernhard Poerksen (back cover)”. Von Foerster, a leading figure of systems theoretical circles in the mid-20th Century, rejects all thought stream labels in this book except being a Viennese although he is widely recognized as a radical constructivist. The book is written after his active career in 2002.

The first Chapter, Images of Reality, describes how human neural systems can only observe their environment with perturbations that are not specific. Thus, it rejects all truth claims based on correspondence between human knowledge and being. It provocatively casts doubt on all causal explanatory principles presented by scientific realism, including gravity and evolution. The Chapter emphasizes the ethicality of second-order observations such as describing descriptions and explaining explanations.

Our discussion

The book divided our sympathies. Some liked it, some were annoyed or almost angry and some remained ambiguous. Many agreed that academia needs more inspiring dialogues and attempts to defend bold positions in conversations. Many were also inspired by some of Von Foerster’s ideas and ideals at large. The minority, who were sympathetic to the text, read it as an anti-thesis rather than a synthesis; as reactive rather than refined. The majority was frustrated, not least as Von Foerster does not develop his ideas, but only keeps ‘dropping’ them; seems to lack sufficient consistency; and the dialogue format is pointless since Von Foerster dodges so many of the most relevant questions.

We presumed that Von Foerster’s background as a magician contributed to his tendency to seek to shock with his anti-thetical statements to realism, which made him appear as a more extremist thinker than warranted by his constructivism. He posited that the system constructs its world and all knowledge about it, but he also argued against solipsism and anti-realism. He seems to agree with the existence of the system’s environment, but with the impossibility of creating knowledge that corresponds with the environment. In sum, his system’s theoretical underpinnings support metaphysical but reject epistemological realism.

We considered Von Foerster’s presentation insufficient for any sociological reading due to its methodological individualism. He wanted e.g. to replace the concept of truth with trust. This might work for local interactions – while many doubted even that – but it remains unclear how this change could be applied to globally spanning communication. Would trust in scientists eventually dilute into something like trust in politicians or journalists? We concluded that the book presents a sample of ideas from Von Foerster’s active career rather than integrating into subsequent theoretical developments in radically constructivist systems theories such as social systems theory.

TSElosophers also discussed ethics. Von Foerster associated all references to the external as excuses for people to free themselves from the responsibility of their decisions. He promoted people not to trivialize themselves, but retain the unpredictability of the non-trivial machines. However, we feel the argument is more balanced when you also recognize that interaction benefits from predictability and the common use of explanatory principles. Certainly, most people should not (and could not) make their world as complex as Von Foerster has done for himself.
