'This impressive work shows the virtues of building understanding across divides: between theory and practice and across such varied topical areas as security, environment, and business. Through its original and thought-provoking chapters, the book shows how the idea of responsibility invokes the expectations communities have for appropriate behaviour – and why and how those expectations are regularly contested. The sum of the chapters provides significant insight into why responsibility is now a critical point of reference in international relations scholarship and beyond.'
