There's something very profound at the core of this book. If it's hard to fully understand exactly what, it's no fault of the authors who explain the ideas remarkably clearly. Rather, I think the concepts challenge the reader to think in such a fundamentally different way that understanding, applying and reconciling them with current models of management, problem-solving, and developed-world 21st century living, seems almost impossible.
The ideas cut across the natural and social sciences, and because they challenge us to alter our thinking and behaviour, they cross the boundary into the world of ethics and the humanities too. It's basically a book about systems thinking: it provides a theoretical basis for the law(s) of unintended consequences in the behaviour and management of complex systems. It's written engagingly with plenty of real-world examples, grounding all the conceptualising in reality.
It's a slim book: succinct, easy to read, and can be polished off in a clear afternoon. But it leaves you wanting to know more. Although there are tantalising glimpses of how resilience theory might be applied to human systems, and the examples all involve an element of human (mis)management in a wider ecosystem, the ideas remain firmly rooted in the science of ecology. Of course, we're all part of one big social-ecological-geological system, but the vast majority of people are only consciously aware of the 'social' part, and the focus on settings which might seem unusual for typical developed world suburban readers-- such as the Florida everglades, Caribbean coral reefs, a rural region of Australia-- might leave them wondering quite how the concepts apply to them.
That said, this is clearly a rapidly evolving field of study, and I don't know of a better introduction to it. Thoroughly recommended.
