2 The clearest and simplest application of the Chicago approach to normative social questions can be found in Friedman, M., Capitalism and Freedom (Chicago: University of Chicago Press, 1962)Google Scholar and , M. and Friedman, R., Free to Choose (London: Seeker and Warburg, 1980)Google Scholar. See also Stigler, George, The Citizen and the State (Chicago: University of Chicago Press, 1975)Google Scholar. It is perhaps misleading to identify so closely the views of Friedman with the Chicago School, since some political economists associated with Chicago, such as Frank Knight and Henry Simons, had different methodological views and also structured their versions of liberalism somewhat differently. However, I have used the Friedmanite system of Chicago liberalism for expository convenience rather than historical accuracy.
