In 'The Morality of Law', legal philosopher Lon L. Fuller explores the ethical foundations of law and its relationship to civil liberties. Fuller argues that law should be based on moral principles and that a just legal system is essential for the protection of individual rights. He examines various ethical theories and their implications for the law, addressing topics such as legal positivism, natural law, and the limits of state power. This thought-provoking book offers a nuanced perspective on the intersection of ethics, law, and civil liberties.
