This book explores the foundations of the debate by examining human interrelations with Nature. It takes an educational perspective, but also draws on evidence from anthropology, economics, ecology, policy sciences and natural history. The case presented is that any coherent view of the purposes and potential of education requires a theory of human society in the natural world. For such a theory, education (and, more broadly, learning) must be more than an instrument for the achievement of personal or policy goals. Rather, it is an integral, continuing and necessary component of personal and policy development. On this basis, a novel approach to curriculum design and implementation is outlined.
