Ludwig von Mises, a classical liberal who greatly influenced right-libertarianism, later opined that Lassalle tried to make limited government look ridiculous, but that it was no more ridiculous than governments that concerned themselves with "the preparation of sauerkraut, with the manufacture of trouser buttons, or with the publication of newspapers". Robert Nozick, a right-libertarian advocate of minarchism, received a National Book Award in category Philosophy and Religion for his book Anarchy, State, and Utopia (1974), where he argued that only a minimal state limited to the narrow functions of protection against "force, fraud, theft, and administering courts of law" could be justified without violating people's rights. Neo-classical liberalism Traditionally, liberalism's primary emphasis was placed on securing the freedom of the individual by limiting the power of the government and maximizing the power of free market forces. As a political philosophy, it advocated civil liberties under the rule of law, with an emphasis on economic freedom. Closely related to economic liberalism, it developed in the early 19th century, emerging as a response to urbanization and to the Industrial Revolution in Europe and the United States. It advocated a limited government and held a belief in laissez-faire economic policy.Dickerson, M. O. et al. (2009). An Introduction to Government and Politics: A Conceptual Approach. p. 129. Built on ideas that had already arisen by the end of the 18th century such as selected ideas of John Locke, Adam Smith, Thomas Robert Malthus, Jean-Baptiste Say and David Ricardo, it drew on classical economics and economic ideas as espoused by Smith in The Wealth of Nations and stressed the belief in progress, natural law and utilitarianism. These liberals were more suspicious than conservatives of all but the most minimal government and adopted Thomas Hobbes's theory of government, believing government had been created by individuals to protect themselves from one another. The term classical liberalism was applied in retrospect to distinguish earlier 19th-century liberalism from the newer social liberalism. Neoliberalism emerged in the era following World War II during which social liberalism was the mainstream form of liberalism while Keynesianism and social democracy were the dominant ideologies in the Western world. It was led by neoclassical economists such as Friedrich Hayek and Milton Friedman, who advocated the reduction of the state and a return to classical liberalism, hence the term neo-classical liberalism, not to be confused with the more left-leaning neoclassical liberalism,Tomasi, John; Zwolinski, Matt (2
