Behavior/Maturana: not determined by semantic or functional values, but by the structure of the nervous system. - E.g. flight and landing are irrelevant to the internal dynamics of the aircraft (system). - ((s) structure determines behavior, but not vice versa.) - Behavior: changing relations and interactions of an organism with its environment, such as those described by an observer.
Behavior/Organism/Body/Maturana: different organisms can produce the same behavior - therefore from the behavior can not be inferred the physiology. - Regularity is always part of the description.
