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.

Models can easily become so complex that they are impenetrable, unexaminable, and virtually unalterable.

We don't think a sustainable society need be stagnant, boring, uniform, or rigid. It need not be, and probably could not be, centrally controlled or authoritarian. It could be a world that has the time, the resources, and the will to correct its mistakes, to innovate, to preserve the fertility of its planetary ecosystems. It could focus on mindfully increasing quality of life rather than on mindlessly expanding material consumption and the physical capital stock.
