Whenever a gradient is applied to a system, insofar as constraints allow, the gradient is spontaneously degraded as completely as possible. Constraints, of course, are not trivial. In life they entail extremely complex feedback loops as energy is channeled through chemical kinetics….Constraints regulate dynamic processes, but they don’t cause them.
