Centrality paradox means that the more integrating the form – that is the more it approximates the circular form – then the more its most integrated internal zone is maximally segregated from the external world, and, by definition, from any other aggregates that are to be found in the vicinity of the system. Put it simply, maximising internal integration also maximises external segregation.
