"Measured in terms of direct impact on environmental thinking and policy, Norton is arguably one of the top two or three environmental philosophers in the world. His reputation and import are demonstrated perfectly in this book. . . . [He] has produced yet another piece of important environmental scholarship. Natural resource management, and students thereof, would be greatly served by carefully considering the view of regimes such as adaptive management throught the critical lens of philosophical analysis. I can think of few better prompts for critical thought than Norton's treatise."
— Michael P. Nelson, Environmental Conservation
"Sustainability is the great synthesis of Bryan Norton's environmental thought. It is a comprehensive philosophical treatment of adaptive management of ecosystems, that is, how humankind may continue its life on Earth in decent conditions for the indefinite future. Considering its length and the systematic coverage of issues, there is hardly any single work comparable to it in the field of academic environmental philosophy. It is also exceptional in the sense that there is something in it for most environmental experts, from philosophy and economics to environmental politics, risk analysis, natural resources management and conservation ecology. Norton does not speak merely to his colleagues in philosophy."
