Shearmur argues for the importance of Popper’s ideas about World 3, and against the idea that they should be re-interpreted in social terms. However, he also argues for the importance of Popper’s ideas about methodological rules—and that these may be given a partially social interpretation. The content of our ideas may in consequence differ from what we take it to be, as a consequence of our institutions and practices operating as methodological rules. He also explores related ideas about the interplay (...) between World 3 and social factors in connection with Darnton’s ideas about the book and work that has built on it, and related issues about the public sphere and the problem of effective deliberative feedback on public policy.

Karl Popper's methodology highlights our scientific ignorance: hence the need to institutionalize open‐mindedness through controlled experiments that may falsify our fallible theories about the world. In his endorsement of “piecemeal social engineering,” Popper assumes that the social‐democratic state and its citizens are capable of detecting social problems, and of assessing the results of policies aimed at solving them, through a process of experimentation analogous to that of natural science. But we are not only scientifically but politically ignorant: ignorant of the (...) facts that underpin political debate, which are brought to our attention by theories that, as Max Weber emphasized, can be tested only through counterfactual thought experiments. Public‐opinion and political‐psychology research suggest that human beings are far too unaware, illogical, and doctrinaire to conduct the rigorous theorizing that would be necessary to make piecemeal social engineering work. F.A. Hayek realized that the public could not engage, specifically, in piecemeal economic regulation but failed to draw the conclusion that this was due to a specific type of political ignorance: ignorance of economic theory.

Hayek's attack on the ideal of social justice, though long ignored by political theorists, has recently been the subject of a number of largely unsympathetic studies (those of Lukes and Johnston being the most recent) in which his critique is dismissed as at best simply mistaken and at worst frivolous. The responses to Hayek's case against social justice, however, fail to draw any blood, for they do not seriously deal with Hayek's central claim that the very notion of social justice (...) is incoherent.

In his biography of Karl Popper, Malachi Hacohen brilliantly reconstructs the development of Popper's ideas through 1946, correcting many errors regarding the sequence of their emergence. In addition he recreates Popper's Vienna and provides insights into Popper's complex personality. A larger goal of Hacohen's narrative is to show the relevance of Popper's philosophical and political thought for the left. Unfortunately this leads him to neglect and distort certain aspects of the story he tells, particularly when it comes to the relationship (...) between Popper and F.A. Hayek. (shrink)

Scholars have argued that transnational networks of right-wing economists and activists caused the worldwide embrace of neoliberalism. Using the case of an Italian think tank, CESES, associated with these networks, the author shows that the origins of neoliberalism were not in hegemony but in liminality. At CESES, the Italian and American right sought to convert Italians to free market values by showing them how Soviet socialism worked. However, CESES was created in liminal spaces that opened up within and between Soviet (...) socialism and Western capitalism after the death of Joseph Stalin in 1953. Scholars from East and West at CESES developed new knowledge about actually existing socialism, which, due to the shifting context of the Cold War, seemed to provoke left-wing sympathies among the scholars and the students involved. CESES in fact required left-wing scholars, who had necessary skills and a fascination with a common project of democratic or market socialism, to create this new knowledge. The new knowledge that developed out of an East–West dialogue not only helped right-wing transnational networks to reorient their hegemonic projects, but also helped those on the left to understand actually existing socialism and what socialism might become. This knowledge could not be obtained without this dialogue and had to travel through liminal spaces. (shrink)

Karl Popper and Friedrich von Hayek became close friends soon after they first met in the early 1930s. Ever since, they discussed their ideas intensively on many occasions. But even though an analysis of the origins and contents of their ideas and correspondence reveals a number of important and fundamental differences, they rarely criticize each other in their published work. The article analyzes in particular the different ideas they have on the role of reason in society and on rationalism and (...) the roots of these differences. Popper’s “Towards a Rational Theory of Tradition” of 1948 contains a criticism of Hayek’s idea—published, for instance, in “Individualism: True and False” of 1945—that we must accept tradition without trying to change it. An analysis of the differences between the two authors touches on topics such as the possibility of public intervention in society, the role of social science in this, the methodology of social science, and the differences between liberalism and social democracy. The article concludes with some possible explanations for Popper and Hayek downplaying their differences in public. The fact remains that they never resolved the tension between Popper’s critical rationalism and Hayek’s conservative rationalism. (shrink)
