Joseph Raz (1939–2022) was a towering figure in late 20th century and early 21st century analytical philosophy. His work in moral, political, and legal philosophy profoundly influenced the discipline, informing debates about practical reasoning, value theory, foundations of liberalism, personal autonomy, perfectionism, the nature of authority, theories of rights, free expression, multiculturalism, the nature of promises, the rule of law, toleration and pluralism, and the nature of law, among others. This collection—the product of two highly selective, international conferences held in Raz's honour soon after his passing—pays tribute to Raz's enormous influence in moral, political, and legal philosophy. The collected essays all engage with Raz's work, but not necessarily as critiques or interpretations of his work. The collection is a testament to Raz's impact, direct and indirect, on a wide range of philosophical issues and on a large and diverse set of philosophical communities. The overarching themes tackled in the collection include: 1. Normativity and Values, 2. Practical Reasoning, 3. Agency and Autonomy, 4. Rights and Obligations, 5. The Public Domain, and 6. Authority. Contributors include both leading figures and rising stars.
