Freedom from government control. Reduced regulation. More individual liberty. Libertarianism seems fairly straightforward on the surface, but it has won itself a reputation akin to a cult in the American political landscape. How has it created such a big tent that includes both conservatives and liberals? What are its policies, and how do these principles play out in the real world? With the support of Republican heavyweights such as Alan Greenspan and Ron Paul, libertarianism has taken centre stage while revealing little about itself to the American public. Here, acclaimed Harvard economist Jeff Miron sets the record straight with a no-frills dictionary that takes the reader beyond the 'keep your government off my rights' surface of libertarian thought. Miron takes us beyond the movement's controversial stances on prostitution and drug use. With entries ranging from Abortion to the War on Terror, Miron explains how Libertarian principles address real-world challenges. Libertarianism, from A to Z, has everything a bourgeoning Libertarian - or curious citizen - needs to know.
