First published in response to A Theory of Justice by his fellow Harvard philosophy academic John Rawls, Robert Nozick's Anarchy, State, and Utopia won the National Book Award in 1975 and has since become one of the defining texts in libertarian thought. Challenging and ultimately rejecting liberal, socialist, and conservative agendas, Nozick boldly argues that the rights of individuals are violated as a state's responsibilities increase, and the only way to avoid these violations rests in the creation of a minimalist state limited to protection against force, fraud, theft, and the enforcement of contracts. The book remains a philosophically rich defense of economic liberalism and this revised edition introduces Nozick and his work to a new generation of readers.
