"The very way we think about the world and create the reality that grounds and justifies our actions leads to unsustainability and impedes a move to sustainability. But virtually every answer to every question we grapple with comes out of our view of reality.
In a sense, we are stuck in the system that has created our dilemmas. Until we begin to dwell in a new, sustainability world, we will have lots of questions but few answers that seem to fit.
If you can discipline yourself to live inside of the questions that are surely raised here, then you will be able to slowly discard the old tried, but no longer true answers and replace them with new effective ways to build a sustainable future."
