In Modernization and the Structure of Societies, Marion Levy shows the interdependencies of societies as a systematic whole in matters that are relevant for international affairs. He distinguishes different types of societies while simultaneously showing elements common to all societies. In a new epilogue being added to this edition, titled Modernization Exhumed, the author alleges that criticism of modernization theory has generally been ideological or otherwise nonscientific. He provides a strong defense of his hypothesis. In his new introduction, he concentrates on the concept of interdependency. Modernization and the Structure of Societies is crucial to the understanding of contemporary international problems. It is a necessary addition to the personal libraries of sociologists, political scientists, and scholars of international affairs.
