I've been reading about Cybernetics, specifically the ideas of Stafford Beer and Luhmann.
Beer states in what he calls "the principle of Cybernetic Isomorphism" that autopoietic systems are made up of parts which are themselves autopoietic systems. They are nested within each other.
Luhmann states that no super-system made of autopoietic systems is possible, because their operational closure precludes it.
So my question is this, can autopoietic systems be made up of other autopoietic systems or not? Is there a consensus in cybernetics on this matter, or is it an open question?
Also, I can find citations for these two writers if that would be helpful.
