However this particular kind of statistical delineation between states only arises given coupling.

boundaries (Markov blankets) is autopoietic (self-organising). In other words the system appears to minimise free energy and engages in active inference and thereby actively maintain its functional and structural integrity. Both a heuristic proof and proof of principle were provided to support this claim.

3.6.4 Markov Blankets and Boundaries A Bayesian network can have a large number of nodes and the probability of a given node can be affected by instantiating a distant node. However it turns out that the instantiation of a set of close nodes can shield a node from the effect of all other nodes. The next definition and theorem show this.
