Who ought to do what, and for whom, if global justice is to progress? In this collection of essays on justice beyond borders, Onora O'Neill criticises theoretical approaches that concentrate on rights, yet ignore both the obligations that must be met to realise those rights, and the capacities needed by those who shoulder these obligations. She notes that states are profoundly anti-cosmopolitan institutions, and that even those committed to justice and universal rights often lack the competence and the will to secure them, let alone to secure them beyond their borders. She argues for a wider conception of global justice, in which obligations may be held either by states or by competent non-state actors, and in which borders themselves must meet standards of justice. This rich and wide-ranging collection will appeal to a broad array of academic researchers and advanced students of political philosophy, political theory, international relations and philosophy of law.
