The "Treatises on Legal Sociology" by Manfred Rehbinder provide a comprehensive collection of his most significant contributions to fundamental questions and methods of legal sociology. On the occasion of his 60th birthday, this edition gathers central themes that engage critically with legal sociology. Rehbinder aligns himself with the great traditions of the discipline and promotes an interdisciplinary dialogue between legal sociology, comparative law, legal history, and legal dogmatics. The texts are not only of historical relevance but also of lasting contemporary significance, as they address current challenges such as pluralism, democratic theory, and discrimination. The works offer valuable insights into the limits of knowledge within the individual disciplines and demonstrate how interdisciplinary approaches can open up new perspectives. This collection is thus of interest to both students and professionals who deal with the complex relationships between law and society.
