The Ethics of Liberty

The Ethics of Liberty is divided into five parts,[6] although a previous edition lacked the fifth.[4] Part I is an introduction, which explains the outlines of natural law theory in general and defends it briefly against some objections. Part II is the substance of the work itself, setting forth Rothbard's ethics regarding the use of force. Part III applies his ethical theories to the State, which he viewed as "the inherent enemy of liberty and, indeed, of genuine law". Part IV offers brief reviews of alternative political theories developed by Mises, Hayek, Berlin, and Nozick.[4] Part V attempts to set forth a theory of strategy of how to move from the present system to a libertarian anarcho-capitalist society.[6]

In an introduction, Hoppe writes that The Ethics of Liberty was Rothbard's second magnum opus, the other being Man, Economy, and State (1962).[7]

Reception of the book has been positive in libertarian circles. Many praise the book for its incisive analysis of natural law and its practical applications. Libertarian commentator Sheldon Richman says: "The Ethics of Liberty is a great book that deserves the attention of anyone interested in the good society and human flourishing."[8]

The philosopher Matt Zwolinski criticized the book, writing that "Rothbard's discussion of self-ownership in chapter six rests on a fundamental confusion between descriptive and normative claims."[9]
