Author and Philosopher. He was one of the most prominent advocates of legal positivism and is well known for his conception of perfectionist liberalism. He spent most of his career as a professor of philosophy of law at the University of Oxford associated with Balliol College, and was later a part-time professor of law at Columbia University Law School and a part-time professor at King's College London. He received the Tang Prize in Rule of Law in 2018. His first book, "The Concept of a Legal System," was based on his doctoral thesis. A later book, "The Morality of Freedom" won two prizes: the 1987 W.J.M. Mackenzie Book Prize from the Political Studies Association of the United Kingdom, awarded to the best book in political science each calendar year; and the 1988 Elaine and David Spitz Book Prize from the Conference for the Study of Political Thought, New York, awarded annually for the best book in liberal and/or democratic theory that had been published two years earlier. The book develops a conception of perfectionist liberalism. He was acknowledged by his contemporaries as being one of the most important legal philosophers of his generation. He authored and edited twelve books, namely "The Concept of a Legal System" (1970), "Practical Reason and Norms" (1975), "The Authority of Law" (1979), "The Morality of Freedom" (1986), "Authority' (1990), "Ethics in the Public Domain" (1994), "Engaging Reason" (1999), "Value, Respect and Attachment" (2001), "The Practice of Value" (2003), "Between Authority and Interpretation" (2009), "From Normativity to Responsibility" (2011) and "The Roots of Normativity" (2022). His most recent work deals less with legal theory and more with political philosophy and practical reasoning. In moral theory, he defended value pluralism and the idea that various values are incommensurable.
