Heinz von Foerster quotes
Heinz von Foerster was an Austrian-American scientist and philosopher, renowned for his work in cybernetics and systems theory. His interdisciplinary approach combined physics, mathematics, and philosophy to explore the nature of cognition and communication. He became a central figure in second-order cybernetics and influenced generations of thinkers in science and the humanities. Here are 10 of his quotes:
It seems that cybernetics is many different things to many different people. But this is because of the richness of its conceptual base; and I believe that this is very good, otherwise cybernetics would become a somewhat boring exercise. However, all of those perspectives arise from one central theme; that of circularity. When, perhaps a half century ago, the fecundity of this concept was seen, it was sheer euphoria to philosophize, epistemologize, and theorize about its unifying power and its consequences and ramification on various fields. While this was going on, something strange evolved among the philosophers, the epistemologists and, the theoreticians. They began to see themselves more and more as being included in a larger circularity; maybe within the circularity of their family; or that of their society and culture; or even being included in a circularity of cosmic proportions!

While in the first quarter of this century physicists and cosmologists were forced to revise the basic notions that govern the natural sciences, in the last quarter of this century biologists will force a revision of the basic notions that govern science itself. After that "first revolution” it was clear that the classical concept of an "ultimate science”, that is an objective description of the world in which there are no subjects (a "subjectless universe”), contains contradictions.

The main theme of this report is a particular facet of the general problem of pre-organization in self-organizing systems, namely, the theory and circuitry of information processing networks. One may consider these networks as a special type of parallel computation channels which extract from the set of all possible inputs a particular subset which is defined by the internal structure of the network. The advantage of such operationally deterministic networks in connection with adaptive systems is the obvious reduction in channel capacity of the adaptors, if it is possible to predetermine classes of inputs which are supposed to be meaningful for those interacting with the automaton.

To remove these one had to account for an "observer” (that is at least for one subject):
(i) Observations are not absolute but relative to an observer's point of view (i.e., his coordinate system: Einstein);
(ii) Observations affect the observed so as to obliterate the observer's hope for prediction (i.e., his uncertainty is absolute: Heisenberg).
After this, we are now in the possession of the truism that a description (of the universe) implies one who describes it (observes it).

I don't know where my expertise is; my expertise is no disciplines. I would recommend to drop disciplinarity wherever one can. Disciplines are an outgrowth of academia. In academia you appoint somebody and then in order to give him a name he must be a historian, a physicist, a chemist, a biologist, a biophysicist; he has to have a name. Here is a human being: Joe Smith -- he suddenly has a label around the neck: biophysicist. Now he has to live up to that label and push away everything that is not biophysics; otherwise people will doubt that he is a biophysicist. If he's talking to somebody about astronomy, they will say "I don't know, you are not talking about your area of competence, you're talking about astronomy, and there is the department of astronomy, those are the people over there," and things of that sort. Disciplines are an aftereffect of the institutional situation.
