How do we appreciate the good without letting it be the enemy of the perfect? How do we keep a step in the right direction from becoming a stopping point? How do we get beyond shades of insipid light green?

Since the Earth is finite, and we will have to stop expanding sometime, should we do it before or after nature's diversity is gone?

A good leader sets the right goals, gets things moving, and helps us to discover that we already know what to do.

The climate continues to deteriorate.

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.

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.

It is in this space of mastery over paradigms that people throw off addictions, live in constant joy, bring down empires, get locked up or burned at the stake or crucified or shot, and have impacts that last for millennia.
