What is missing from the policy analyst's tool kit -- and from the set of accepted, well-developed theories of human organization -- is an adequately specified theory of collective action whereby a group of principals can organize themselves voluntarily to retain the residuals of their own efforts.

In some settings, however, rampant opportunistic behavior severely limits what can be done jointly without major investments in monitoring and sanctioning arrangements.

Bureaucrats sometimes do not have the correct information, while citizens and users of resources do.

Some of the homes that have been built in the last 10 years just appall me. Why do humans need huge homes? I was born poor and I didn’t know you bought clothes at anything but the Goodwill until I went to college.

We have to think through how to choose a meaningful life where we’re helping one another in ways that really help the Earth.

Brian Walker and David Salt have written a thoughtful and powerful book to help resource users and managers put resilience thinking into practice and aim toward increasing the sustainability of our world. I urge public officials, scholars, and students in public policy programs to place this volume on their list of must-read books. It is a powerful antidote to the overly simplified proposals too often offered as solutions to contemporary problems at multiple scales.
