The observation of energetic and causal coupling confronts a complexity of phenomena that overwhelms the Observer and forces a switch from "understanding" to "Control" (that is: Memory) (Morin 1972; Ashby 1958).


The contribution by Luc Ciompi (see also Ciompi 2002), which triggered the discussion, points to a remarkable gap in research not only in the work of Luhmann, but also in systems theory in general.
