"Let's face it, the universe is messy. It is nonlinear,
turbulent, and chaotic. It is dynamic. It spends its time in
transient behavior on its way to somewhere else, not in
mathematically neat equilibria. It self-organizes and
evolves. It creates diversity, not uniformity. That's what
makes the world interesting, that's what makes it
beautiful, and that's what makes it work."
Donella H. Meadows
(Thinking in Systems: A Primer)
