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)

I first met Hans Albert in 1974, when together with two friends, Rob de Vries and Berry van Berkel, I participated in the European Forum Alpbach for the first time. We attended the seminar that was led by John Watkins and Walter Kaufmann and, of course, went to as many of the plenary meetings as possible. At the time, the seminar week and the bulk of the plenary events were still organized during the same period and were included in the (...) fee, neither of which is unfortunately the case any longer.

F. A. Hayek’s The Sensory Order (1952) is often considered to be a theory of cognitive psychology. While it contains a theory on the psychology of perception, it has the function of illustrating Hayek’s solution to the mind–body problem. The solution, which has been strongly influenced by Moritz Schlick’s epistemology, takes the form of a physicalist identity theory. An attempt is made to trace Schlick’s influence on Hayek to the latter’s stay in Zürich, which resulted in a manuscript (1920) that (...) contains the main features of the 1952 book. One of the consequences of Hayek’s theory is that we cannot describe the functioning of our mind completely without using expressions that refer to subjective experiences. For Hayek this is not a fundamental problem but a practical one that does not jeopardize his physicalist identity theory. Unlike the manuscript, The Sensory Order contains a rudimentary sketch of an evolutionary research program. When Hayek elaborated that program later, though, he focused on cultural evolution rather than on the evolution of the mind. (shrink)

This thought-provoking book discusses the concept of progress in economics and investigates whether any advance has been made in its different spheres of research. The authors look back at the history, successes and failures of their respective fields and thoroughly examine the notion of progress from an epistemological and methodological perspective. The idea of progress is particularly significant as the authors regard it as an essentially contested concept which can be defined in many ways – theoretically or empirically; locally or (...) globally; or as encouraging or impeding the existence of other research traditions. The authors discuss the idea that for progress to make any sense there must be an accumulation of knowledge built up over time rather than the replacement of ideas by each successive generation. Accordingly, they are not concerned with estimating the price of progress, reminiscing in the past, or assessing what has been lost. Instead they apply the complex mechanisms and machinery of the discipline to sub-fields such as normative economics, monetary economics, trade and location theory, Austrian economics and classical economics to critically assess whether progress has been made in these areas of research. -/- Bringing together authoritative and wide-ranging contributions by leading scholars, this book will challenge and engage those interested in philosophy, economic methodology and the history of economic thought. It will also appeal to economists in general who are interested in the advancement of their profession. (shrink)
