Otto Neurath’s empiricist methodology of economics and his contributions to politi- cal economy have gained increasing attention in recent years. We connect this research with contemporary debates regarding the epistemological status of thought experiments by reconstructing Neurath’s utopias as linchpins of thought experiments. In our three reconstructed examples of different uses of utopias/dystopias in thought experiments we employ a reformulation of Häggqvist’s model for thought experiments and we argue that: (1) Our reformulation of Häggqvist’s model more adequately complies with many (...) uses of thought experiments, especially with the open-ended discussions of utopias and dys- topias in thought experiments. (2) As a strict logical empiricist, Neurath is committed to a strictly empiricist account of thought experiments. John Norton’s empiricist argument view can indeed account for the justifications of empirical beliefs and genuine discoveries targeted by scientific utopianism in three distinct (yet connected) ways, all of which Neur- ath already contemplated: (2.I) Dealing with utopias and thought experiments on a regular basis increases creativity and inventiveness. (2.II) Particular ways of presenting knowl- edge facilitate scientific discovery and social progress. (2.III) The use of utopias in thought experiments can prompt conceptual change and allow access to new phenomena. We con- clude by highlighting that, even though thought experiments support a positive attitude for exploring new social possibilities, Neurath points out that active decisions are unavoidable. The exploration of alternatives and the awareness of a need for decisions in policy discus- sion avert a technocratic outlook in social science. (shrink)

This book presents a concise introduction to the epistemology and methodology of the Austrian School of economics as defended by Ludwig von Mises. The author provides an innovative interpretation of Mises’ arguments in favour of the a priori truth of praxeology, the received view of which contributed to the academic marginalisation of the Austrian School. The study puts forward a unique argument that Mises – perhaps unintentionally – defends a form of conventionalism. Chapters in the book include detailed discussions of (...) individualism, historicism, epistemological positions, and essentialism. The author goes on to discuss Mises’ justification of the fundamental axiom and proposes a conventionalist interpretation. By presenting praxeology as a conventionalist research programme, the author aims to reinvigorate the interaction between the Austrian School, mainstream economics, and the philosophy of science. This comprehensive reconstruction is suitable for economists interested in the history and philosophy of their discipline, as well as for philosophers of science. (shrink)

Current debates between behavioural and orthodox economists indicate that the role and epistemological status of first principles is a particularly pressing problem in economics. As an alleged paragon of extreme apriorism, the methodology of Austrian economics in Mises’ tradition is often dismissed as untenable in the light of modern philosophy. In particular, the defence of the so-called fundamental axiom of praxeology—“Man acts.”—by means of pure intuition is almost unanimously rejected. However, in recently resurfacing debates, the extremeness of Mises’ epistemological position (...) has been called into question. Rather than directly engaging in these exegetical discussions, this paper aims to substantiate the possibility and plausibility of conventionalist defences of praxeology per se. The proposed shift includes settling for an analytic fundamental axiom and acknowledging the prima facie tenability of other research programs than praxeology. Since conventionalist praxeology is only moderately aprioristic, mainstream economists and philosophers might be more likely to engage in fruitful discussions with those Austrian scholars who elaborate pragmatic arguments for praxeology instead of invoking pure intuition.

Mainstream economics has been accused of excessive mathematization, whereas the rejection of mathematical and other formal methods is often cited as a crucial trait of Austrian economics. Based on a systematic discussion of potential benefits and drawbacks of formalization, this paper corroborates legitimate concerns that predominant types of mathematization induce a shift of attention away from the key concepts of Austrian economics. Taking this shift to the extreme, predominant modes of mathematization tend to accompany a detachment from ‘reality’ incompatible with (...) Austrian pleas for realisticness. Contrary to popular prejudice however, the most prominent representatives of the Austrian School including Carl Menger, Ludwig Mises, Friedrich Hayek, Israel Kirzner, and Peter Boettke neither provide a justification for a wholesale rejection of formalization nor actually reject it. Adequate formalization can serve as a remedy for lacking logical and semantic rigor in standard mathematical economics as well as in murky verbal chains of reasoning. (shrink)

Austrian economist Ludwig Mises’s central role in the socialist calculation debates has been consensually acknowledged since the early 1920s. Yet, only recently Nemeth, O’Neill, Uebel, and others have drawn particular attention to Mises’s encounter with logical empiricist Otto Neurath. Despite several surprising agreements, Neurath and Mises certainly provide different answers to the questions “what is meant by rational economic theory” (Neurath) and whether “socialism is the abolition of rational economy” (Mises). Previous accounts and evaluations of the exchange between Neurath and (...) Mises suffer from attaching little regard to their idiosyncratic uses of the term “rational.” The paper at hand reconstructs and critically compares the different conceptions of rationality defended by Neurath and Mises. The author presents two different resolutions to a detected tension in Mises’s deliberations on rationality: the first is implicit in Neurath’s, O’Neill’s, and Salerno’s reading of Mises and faces several interpretational problems; the author proposes a divergent interpretation. Based on the reconstructions of Neurath’s and Mises’s conceptions of rationality, the author suggests some implications with respect to Viennese Late Enlightenment and the socialist calculation debates.

Writing a captivating book about a bureaucrat and his statistical modelling techniques is impossible? Erwin Dekker’s biography of Jan Tinbergen proves otherwise. As he has done before, Dekker tells the history of economic thought and methodology as part and parcel of general intellectual and cultural history. Nevertheless, he never downplays or neglects the analysis of inner-scientific problem situations. Drawing on rich archival material and conversations with Tinbergen’s family, students, and colleagues, Dekker vividly introduces us to an extraordinary personality and career. (...) Tinbergen of course was so much more than a Dutch bureaucrat and Nobel Prize winning econometrician. He became a key figure in transforming the discipline of economics. Perhaps even more sweeping – and reaching far beyond academia – is Tinbergen’s re-invention of the role played by economists in the modern nation state and in the international community. Ultimately, he spearheaded a shift in the public notion of how malleable “the economy” is by conscious policy efforts – or so Dekker convincingly exhibits and critically discusses. Anybody reflecting on the proper role of scientific experts in democratic societies, may want to pick up Dekker’s entertaining and thought-provoking study. (shrink)

Neurath’s scientific utopianism is the proposal that the social sciences should engage in the elaboration, development, and comparison of counterfactual scenarios, the ‘utopias’. Such scenarios can be understood as centerpieces of scientific thought experiments, that is, in exercises of imagination that not only promote conceptual revision, but also stimulate creativity to deal with experienced problems, as utopias are efforts to imagine what the future could look like. Moreover, utopian thought experiments can offer scientific knowledge to inform political debates and decisions, (...) contributing to the shaping of society. This essay reconstructs a historical event as an example of Neurath’s utopianist methodology. In the late 1970s and early 1980s, a scientific and political commission appointed by the Western German Parliament devised and compared four scenarios for future energetic-economic policies. Conclusions of the commission informed political decisions that put Western (later reunified) Germany in a route towards becoming a green industrial power. A fundamental part of the commission’s work involved an appeal to imagination, allowing for the characterization under Neurath’s methodology. (shrink)

Logical empiricism and the Austrian School of economics are two of the internationally most influential intellectual movements with Viennese roots. By and large independently of each other, both have been subject to detailed historical and philosophical investigations for the last two dec-ades. However, in spite of numerous connections and interactions be-tween the two groups, their relationship has captured surprisingly sparse attention. My dissertation focuses on the many-faceted juxtaposition of two supposedly antagonistic championsof Viennese Late Enlightenment: logical empiricist Otto Neurath and (...) Austrian economist Ludwig Mises. I rationally reconstruct and critically compare their epistemological, meth-odological, and economic positions and demonstrate that a closer look reveals more compatibilities and similarities than acknowledged by the received view and by the protagonists themselves. Over and above the historiographic task of challenging and amending this received view, the analytic components of my thesis inform contemporary debates in phi-losophy, politics, economics, and other sciences.

O utopianismo científico de Neurath é a proposta para que as ciências sociais se envolvam na elaboração, desenvolvimento e comparação de cenários contrafactuais, as ‘utopias’. Tais cenários podem ser entendidos como peças centrais de experimentos de pensamento científicos, isto é, em exercícios da imaginação que não apenas promovem a revisão conceitual, mas também estimulam a criatividade para lidar com problemas vivenciados, já que utopias são esforços para imaginar como o futuro poderia ser. Ademais, experimentos de pensamento utópicos podem oferecer conhecimento (...) científico para informar debates e decisões políticas, contribuindo para formatar a sociedade. Este ensaio reconstrói um evento histórico como um exemplo da metodologia utopianista de Neurath. No final dos anos 1970 e início dos anos 1980, uma comissão científica e política designada pelo parlamento da Alemanha Ocidental inventou e comparou quatro cenários para políticas energético-econômicas futuras. Conclusões da comissão informaram decisões políticas que puseram a Alemanha Ocidental (e depois reunificada) em um caminho para se tornar uma potência industrial verde. Uma parte fundamental do trabalho da comissão envolveu um apelo à imaginação, permitindo a caracterização sob a metodologia de Neurath. (shrink)

In the first part of this paper I review the two most recent biographies on Otto Neurath and Ludwig von Mises as well as the scarce literature on the relations between their lives and ideas. Recent publications by Nemeth, O’Neill, and Uebel reflect growing interest in the connections between these two main proponents of Logical Empiricism and the Austrian School of Economics respectively, but are mainly focused on the so-called socialist calculation debates. In the second part I propose that additional (...) research on Neurath’s and Mises’ idiosyncratic positions is likely to uncover general relations between epistemological assumptions, economic theories, and political views. -/- .

Carl Menger’s Principles of Economics published in 1871 is usually regarded as the founding document of the Austrian School of economics. Many of the School’s prominent representatives, including Friedrich Wieser, Eugen Böhm-Bawerk, Ludwig Mises, Hans Mayer, Friedrich August Hayek, Fritz Machlup, Oskar Morgenstern, and Gottfried Haberler, as well as Israel Kirzner, Ludwig Lachmann, Murray Rothbard, and Don Lavoie, advanced and modified Menger’s research program in sometimes conflicting ways. Yet, some characteristics of the Austrian School remain (nearly) consensual from its foundation (...) through to contemporary neo-Austrian economists. In eight sections, we will briefly discuss some of the philosophical and methodological characteristics of Austrian economics: Austrian action theory and interpretative understanding, a relatively thoroughgoing subjectivism, methodological individualism, ontological individualism, apriorism, essentialism, an often overstated rejection of formal methods, and alertness to economic semantics.

This note identifies and comments on selected crucial traits of Robert Aumann’s philosophy of game theory. In doing so, it aims at carving out and expressing some notions tacitly held by many working game theorists and ideally even at triggering subsequent reflection on the philosophy of game theory in general. According to my reconstruction of Aumann’s position, sophisticated, relatively precise rules of language—an ultra-refined grammar for interactions—constitute the heart of game theory. Consequently, the heart of game theory is devoid, or (...) almost devoid, of empirical content. The final section proposes a nomenclature for lucidly discussing the relationships between theories, different types of models, and “the real world” and employs it to explicate and slightly amend Aumann’s remarks on the role of truth and fruitfulness in game theory.

Im Rahmen dieses Beitrags beleuchten wir, wie Hans Hahn die Einflüsse Russells und Wittgensteins adaptiert, um seine individuelle Variante von Logizismus zu entwickeln. Von Bedeutung ist in diesem Zusammenhang Hahns unterschätzte Vorreiterrolle in der Entwicklung des logischen Toleranzprinzips und des logischen Pluralismus, also der Loslösung von der Vorstellung einer einzigen „korrekten“ Logik. Die detaillierten Arbeiten Uebels (2007, 2009) zur Entwicklung des logischen Pluralismus im Wiener Kreis verdienen zumindest zwei punktuelle Ergänzungen: Erstens untermauern die in diesem Kontext bisher unberücksichtigten Protokolle des (...) Wiener Kreises sowie Vorlesungsmitschriften Hermann Brochs die von Uebel im Gegensatz zu Goldfarb (1996) beschriebene Distanzierung Hahns von Wittgenstein. Zweitens relativieren Hahns und Mengers Arbeiten zu Occams Rasiermesser Uebels Einschätzung, Mengers Beitrag zum Toleranzprinzip sei „wenig philosophisch“. (shrink)

Alex has written an excellent thesis in the area of computable model theory. The latter is a subject that nicely combines model-theoretic ideas with delicate recursiontheoretic constructions. The results demand good knowledge of both fields. In his thesis, Alex begins by reviewing the essential model-theoretic facts, especially the Baldwin-Lachlan result about uncountably categorical theories. This he follows with a brief discussion of recursion theory, including mention of the priority method. The deepest part of the thesis concerns the study of the (...) recursive spectrum of an uncountably categorical theory, i.e. the set of n ≤ ! such that the n-th model of the theory (in the Baldwin-Lachlan sense) has a computable presentation. This is a deep and very active area of conteporary research in computable model theory which Alex discusses in considerable detail. The exposition is very good and therefore the thesis makes a nice introduction to the subject for a wide community of logicians.

Austrian economist Ludwig Mises’s central role in the socialist calculation debates has been consensually acknowledged since the early 1920s. Yet, only recently, Nemeth, O’Neill, Uebel, and others have drawn particular attention to Mises’s pertinent encounter with one of the most colorful characters of “Red Vienna”: logical empiricist and “skeptic utopist” Otto Neurath. Despite several surprising agreements, Neurath and Mises certainly provide different answers to the questions “what is meant by rational economic theory” (Neurath) and whether “socialism is the abolition of (...) rational economy” (Mises). However, previous accounts and evaluations of the exchange between Neurath and Mises suffer from attaching little regard to highlighting their idiosyncratic uses of the term “rational”. The paper at hand reconstructs and critically compares the different conceptions of rationality defended by Neurath and Mises and suggests some consequent insights with respect to Viennese Late Enlightenment, contemporary rationality wars, the socialist calculation debates, and the foundations of welfare economics.
