A system is a set of things people, cells, molecules, or whatever interconnected in such a way that they produce their own pattern of behavior over time... The system, to a large extent, causes its own behavior.

Any system, biological, economic, or social, that gets so encrusted that it cannot self-evolve, a system that systematically scorns experimentation and wipes out the raw material of innovation, is doomed over the long term on this highly variable planet.

I call the transformed world toward which we can move ‘sustainable,’ by which I mean a great deal more than a world that merely sustains itself unchanged. I mean a world that evolves, as life on earth has evolved for three billion years, toward ever greater diversity, elegance, beauty, self-awareness, interrelationship, and spiritual realization.

The world is a complex, interconnected, finite, ecological - social - psychological - economic system. We treat it as if it were not, as if it were divisible, separable, simple, and infinite. Our persistent, intractable global problems arise directly from this mismatch.
