In most systems diversity begets stability.

When the energy available for the formation of complex systems is taken away, these systems revert to a more primitive level of function.

What we call life is neither a thing apart from matter, nor merely "living matter," but an informational and energetic process...

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.

Far-from-equilibrium systems pay for their reduced entropy by exporting a concomitant increase in entropy into the surrounding environment….All organisms, not just human technological ones, produce waste.
