'Long ago, those of us teaching international legal theory looking for a single teaching text had to cobble together (and severely edit) a mountain of sometimes indigestible texts, perhaps supplemented by AJIL's 1999 symposium on 'method.' Dunoff and Pollack have now gifted us with a cornucopia of riches. This is a highly readable collection of 'traditional,' 'critical,' 'post-cold war,' and 'interdisciplinary' frameworks for making sense of the field, capped by three 'dialectic' perspectives by luminaries (Abi-Saab, de Chazournes, and Weiler). The sterling collection of well-crafted essays are written either by those who originated the theoretical approach (e.g., Koh on transnational legal process) or by contemporary adherents most associated with them (e.g., Gathii on TWAIL or the formidable trio of Engle, Nesiah, and Otto on feminist approaches). This is destined to be an indispensable text for those of us who think theory matters. And it may even convince those who think it doesn't. International law geeks (and their students) should give thanks for this most welcome contribution.' J. E. Alvarez, Herbert and Rose Rubin Professor of International Law, NYU School of Law
