• 1 Introduction I. The roots of a postmodern anxiety II. From too little to too much law: mapping the fragmentation debate III. Towards an exploratory philosophy of unity IV. Outline of the book V. Some caveats and clarifications 2 Of Unity, Perspective and Perception: An Ontological Preamble I. From the simple to the complex: elementary unity and unity by composition II. In flesh and ideas: unity as interpretation III. Multi-causational unity IV. Unity and the laws of perspective V. Intermediate conclusions: unity, choice and ruse3 Unity, Unification, Universality: A Terminological Disambiguation I. Unity and unificationII. Unity and universality III. Intermediate conclusions – complexity on the global marketplace of law: the MOX Plant Dispute 4 Material Unity I. The 'no conflict' theory of unity II. The definition of 'norm conflict' in theory and practice III. Intermediate conclusions 5 Formal Unity I. Three conceptions of the legal order II. Taking Hart seriously: secondary rules, determinacy and acceptance III. Issues of determinacy: questioning the sources of international law IV. Issues of acceptance: the International Islamic Court of Justice and the Shari'a as the ultimate rule of recognition V. Intermediate conclusions 6 Cultural Unity I. International law as an intellectual and professional discipline II. The concept of legal culture III. The unity of international law as a cultural system IV. Intermediate conclusions: the invisible hand of legal culture 7 Logical Unity I. Epistemo-logical unity: Ah! In the hypothesis! II. Axio-logical unity III. Intermediate conclusions: the hesitant fettering of the thousand necks 8 General Conclusion: Unitas Multiplex I. Changing lenses: Tadic revisited II. Territorial battles and merchants of unity

The Concept of Unity in Public International Law is an important book for those who are interested in fragmentation theory and international legal theory in general. It challenges traditional international legal epistemology from within and outside the legal perspectives and opens up new research paths. In doing so, it ties together huge amounts of recent and classical literature without losing its main research focus.
