'In a world marked by cascades of ever more complex interdependence, Jack Donnelly persuasively argues that differentiation, not anarchy, should be central to understanding world order. This book is a masterpiece, melding theoretical innovation with broad historical scope.' Daniel H. Deudney, Professor of Political Science, Johns Hopkins University
'At last: a book about international societies as a genus, a book that starts with wholes as parts of wholes, a book that makes sense of levels and layers, a book that fearlessly dispatches Waltz's structuralism for good. A relentlessly systematic, dauntingly detailed book for the ages.' Nicholas Onuf, Professor Emeritus, Florida International University
