This paper has a dual purpose. On the one hand, it suggests ways of making autopoietic theory more precise and more operational for concrete communication analysis. I discuss concepts such as distinction, system, bound- ary, environment, perturbation, and compen- sation. The explication of the concepts is ba- sed on catastrophe theory, and in order to make them operational I emphasise their affinity to traditional semiotics and communi- cation theory. On the other hand I propose changes to the semiotic tradition in order to incorporate insights from autopoietic theory, namely that the human condition is characte- rised by the phenomenon of self-reference and therefore also by the unavoidability of para- doxes. Firstly, this means that truth cannot be a basic semiotic concept; instead the notion of stability is suggested. Secondly, in order to act in a paradoxical context, we need to unfold the paradox in time, which again calls for a dynamic theory of meaning.

Excerpt: In comparing constructivist and sociocultural perspectives, it is worth considering at the outset whether any empirical or scientific claims are involved – claims that could be vulnerable to evidence – or whether the differences are entirely perspectival. The slogan “students construct their own knowledge” is not by itself a falsifiable claim. It is simply a concomitant of any cognitive stance – including the stance of folk psychology. As long as one views the mind as a container whose contents are beliefs, schemata, cognitive structures, or other cognitive objects, then any plausible explanation of how those objects get into the mind has to assume that they are created there. What alternative is there, short of thought transference? The only way to reject it is by rejecting the whole structure of cognitive psychological ideas built upon the mind-as-container metaphor.

When confronted with issues dealing with first and second order cybernetics, it seems that the manner of defining the former has been somewhat caricatured. The second appears to sometimes give rise to conclusions which are almost opposite to those of Wiener by questioning the possibility of a control for a system. We find in Wiener’s research a prefiguration of the autonomy concept, which, in our opinion, could bring an explanation – and a solution – in cases where control elicits some perverse effect; an acceptance of positive feedback if it serves a desired purpose; the central importance held for him by ergodic theory that we use in an addendum on imbalanced strange attractors control; the idea of a knowledge which may be the fruit of the control; an interest for logical paradoxes he put in relation to communication in nervous system; and already the notion of dialogue in the core of the relation man/man or man/machine. Of course, Wiener did not accord an equal development to all his insights, but we have not yet finished scrutinizing his writings. First and second order cybernetics perhaps form an agonistic/antagonistic couple of which neither element could overshadow the other.
