The policy-oriented approach or the New Haven approach to international law deserves close study for many reasons: its incisive critique of political realism and positivism, its ability to raise vital questions and challenge established doctrines, its stress on the essential relationship between law and policy, its radical thesis on semantic and structural sources of indeterminacy, its articulation of interdisciplinary methods of inquiry for policy analysis, its meticulous investigation of diverse areas of international law, its awareness of the growing interpenetration of international and municipal law, its commitment to the goal of human dignity and world public order, its emphasis on the edifying role of international lawyers, and the fact that a host of illustrious names have confessed to being influenced by it.
