4. Political philosophers and the history of political thought
‘Political philosophers and the history of political thought’ discusses the confidence in the 1950s that the ‘right’ system of politics, economy and society had been discovered and linked with a turn away from history and theory. Behavioralism, which was propagated by Heinz Eulau, David Easton, and other political scientists, demanded the analysis of politics through the assertion of claims that could be verified or refuted. Data analysis could test hypotheses and come up with irrefutable policy recommendations. Domestic and international liberalism are coupled with variants of pacific socialism or communitarianism. There are a number of renowned political theorists who turned into public intellectuals, such as Norberto Bobbio and Jürgen Habermass.
