“The Ethics of Liberty” is a seminal work by Murray Rothbard, which is considered one of the most significant contributions to libertarian theory. In the book, Rothbard presents a systematic analysis of the ethical foundations of individual rights, property rights, and the free market economy. He argues that individuals have the right to their lives, liberty, and property and that the government’s role should be limited to protecting these rights. Rothbard explores the implications of this principle for issues such as taxation, regulation, and social welfare, among others. He advocates for a fully voluntary society based on the principles of non-aggression and individualism, in which the state plays no coercive role. “The Ethics of Liberty” remains a classic of libertarian thought and an important reference for anyone interested in the philosophy of freedom.
