The Concept of a Legal System

The Concept of a Legal System examines fundamental questions about the nature and structure of legal systems. Raz analyzes how laws relate to one another and what makes a collection of laws constitute a unified system. The book engages with key legal philosophers like Kelsen and Hart while developing an original theory of legal systems. Through systematic analysis, Raz explores concepts like legal validity, the identity of legal systems, and the relationship between law and the state. The work moves from abstract theoretical foundations to specific applications in modern legal contexts. Raz addresses practical questions about how legal systems handle change, conflict between laws, and gaps in legislation. As a seminal text in legal philosophy, this book presents a framework for understanding how legal systems function as coherent wholes rather than mere collections of rules. The analysis reveals deep connections between the nature of law and fundamental questions about authority, obligation, and social order.
