Murray N. Rothbard's 'The Ethics of Liberty' is a seminal work in the field of libertarian political philosophy. In this book, Rothbard argues for a radical conception of civil liberties based on the principle of self-ownership and non-aggression. Through a rigorous examination of natural rights theory and the ethics of liberty, Rothbard presents a compelling case for the primacy of individual freedoms in a just society. This thought-provoking book challenges conventional notions of ethics and law, offering a unique perspective on civil liberties.
