Leslie Green is a leading figure in late-20th and early-21st century legal philosophy. He has made important contributions on topics as varied as legal positivism, political obligation, the limits of government, and the regulation of pornography. Green's work is marked by its striking originality and approachability, as well as his willingness to see questions in the philosophy of law as integrated with wider questions of moral, political, and social theory. Named after one of Professor Green's most celebrated articles, The Morality in Law is a collection of essays inspired by his work. This eclectic book covers pressing questions of practical philosophy including: What do oppressed citizens owe the state? Should law be used to improve sexual morality? How are legal decisions justified?Thought-provoking and original, this volume advances key debates in legal philosophy while honouring Professor Green's enduring influence.
