In this handy and readable book Murray Rothbard makes the case for a system of ethics that is based on natural law, demonstrating with a wealth of graphic examples how such a system would work in practice. There are valuable chapters here on self defence, childrens rights and criminality.
Moving on to human rights in general, Rothbard makes a compelling case for human rights as property rights, revisiting the famous question as to whether one has the right to shout 'fire' in a crowded cinema.
The book also contains an excellent analysis of the nature of the state and its inner contradictions. Here, Rothbard reminds us how difficult it is to frame a definition of robbery that does not also include taxation.
In conclusion, he presents us with a useful review of some other modern theories of liberty, among them the ideas of Hayek, Nozick and Berlin.
Rothbard's writing is always lively, challenging and provocative and if liberty means anything to you, then this is a book that you will not find easy to put down.
