Just now, I want to set several most interesting points in response to the Sokolowski request.
Complexity replaces simplicity with a small change in an ordered dynamical regime.
Efforts to control a social system require ever more resources as non-linearity increases. Control with positive or negative re-inforcements might work in limited systems such as prisons or corporate bureaucracies but that does not mean that such control extends beyond the walls of prison or the company. Small changes in key variables produce new outcome states in nonlinear regimes. What is interesting is that there just might be the possibility to find the points at which such qualitative changes are about to occur. Mitchell Feaginbaum discovered them in the 70s.
