No one can define or measure justice, democracy, security, freedom, truth, or love. No one can define or measure any value. But if no one speaks up for them, if systems aren’t designed to produce them, if we don’t speak about them and point toward their presence or absence, they will cease to exist.

There is too much bad news to justify complacency. There is too much good news to justify despair.

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

The sustainability revolution will be organic. It will arise from the visions, insights, experiments and actions of billions of people. The burden of making it happen is not on the shoulders of any one person or group. No one will get the credit, but everyone can contribute.

We can't control systems or figure them out. But we can dance with them!

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.

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.
