Should one name one central concept, a first principle, of cybernetics, it would be circularity.
Objectivity is a subject's delusion that observing can be done without him.
Cybernetics is NOT the banana.
If you desire to see, learn how to act.
What we need now is the description of the "describer" or, in other words, we need a theory of the observer.
Objectivity is the delusion that observations could be made without an observer.
