In the rise of modern scientific philosophy, one can distinguish four general periods. Its early phase is part of the intellectual history of 19th-century Austria-Hungary. Second, we find it reaching its self-confident form in the 1920s and early ‘30s, chiefly in the collaborative achievements of the Vienna Circle and its analogous groups in Prague, Berlin, Lwow and Warsaw. Third is the period of its further growth and accommodation during the period roughly from the late 1930s to about (...) 1960, especially in the U.S.A., as mediated largely by the European refugees from fascism. Lastly, the movement’s fate from the 1960s on may be understood as its integration with, or dissolution into, other related modern streams. (shrink)

Richard Rorty has drawn a distinction between three ways philosophers in the 20th Century have conceived of the enterprise of philosophy. There are those who see it as the guardian of the sciences, those who treat it as a kina of poetry, and those who view philosophy as a political exercise. In this paper, I try to show that Wittgenstein, despite certain popular conceptions of his project, belongs more in the third group than in the other two. The paper (...) focuses on Wittgenstein's notes On Certainty in order to reveal the structure of Wittgenstein's notion of epistemological privilege and how it depends on communal agreement and behaviour. The system of conventions and commitments on which our vanouis practices are grounded is not justifiable. It is a matter of forms of life. (shrink)

The invention of Bitcoin in 2008 as a new type of electronic cash has arguably been one of the most radical financial innovations in the last decade. Recently, developer communities of blockchain technologies have started to turn their attention towards the issue of governance. The features of blockchain governance raise questions as to tensions that might arise between a strictly “on-chain” governance system and possible applications of “off-chain” governance. In this paper, we approach these questions by reflecting on a long-running (...) debate in legal philosophy regarding the construction of a positivist legal order. First, we argue that on-chain governance shows striking similarities with Kelsen’s notion of a positivist legal order, characterised by Schmitt as the machine that runs itself. Second, we illustrate some of the problems that emerged from the application of on-chain governance, with particular reference to a calamity in a blockchain-based system called the DAO. Third, we reflect on Schmitt’s argument that the coalescence of private interests is a vulnerability of positivist legal systems, and accordingly posit this as an inherent vulnerability of on-chain governance of existing blockchain-based systems.

This essay introduces the transcription and translation of Paul Feyerabend's "Der Begriff der Verständlichkeit in der modernen Physik" [The concept of intelligibility in modern physics] (1948), which is an early essay written by Paul Feyerabend in 1948 on the topic of intelligibility (Verständlichkeit) and visualizability (Anschaulichkeit) of physical theories. The existence of such essay was likely. It is listed in his bibliography as his first publication. Yet the content of the essay was unknown, as no original or copy is extant (...) in Feyerabend's Nachlass and no known published version was available to the community—until now. The essay has both historical and philosophical interest: it is, as far as our current knowledge goes, Feyerabend's earliest extant publication. It documents Feyerabend's philosophical interest as a physicist-to-be, in what he himself called his “positivist” phase; and it gives a rare if fragmentary insight into the early discussions of the ‘Third Vienna Circle’ and, more generally, the philosophical culture of discussion in Vienna.

This article is intended as a contribution to the current debates about the relationship between politics and the philosophy of science in the Vienna Circle. I reconsider this issue by shifting the focus from philosophy of science as theory to philosophy of science as practice. From this perspective I take as a starting point the Vienna Circle’s scientific world-conception and emphasize its practical nature: I reinterpret its tenets as a set of recommendations that express the particular (...) epistemological attitude in which both the Vienna Circle’s (doing) philosophy of science and its political engagement were rooted. -/- Regarding politics, and referring to new primary sources, I reconstruct how the scientific world-conception placed the Vienna Circle within a neoliberal-socialist political network that pursued concrete political aims. In light of my reconstruction I shall argue that neither the Vienna Circle’s alleged ethical noncognitivism nor its alleged adhesion to the Weberian ideal of a value-free science rules out the possibility of ascribing to the Vienna Circle a politically engaged philosophy of science: the case of the Vienna Circle shows how philosophy of science, as a public activity, can itself become a form of political engagement, even without necessarily entailing a theory of objective values.

Friedrich Nietzsche was among the figures from the history of nineteenth century philosophy that, perhaps surprisingly, some of the Vienna Circle’s members had presented as one of their predecessors. While, primarily for political reasons, most Anglophone figures in the history of analytic philosophy had taken a dim view of Nietzsche, the Vienna Circle’s leader Moritz Schlick admired and praised Nietzsche, rejecting what he saw as a misinterpretation of Nietzsche as a militarist or proto-fascist. Schlick, Frank, Neurath, (...) and Carnap were in different ways committed to the view that Nietzsche made a significant contribution to the overcoming of metaphysics. Some of these philosophers praised the intimate connection Nietzsche drew between his philosophical outlook and empirical studies in psychology and physiology. In his 1912 lectures on Nietzsche, Schlick maintained that Nietzsche overcame an initial Schopenhauerian metaphysical-artistic phase in his thinking, and subsequently remained a positivist until his last writings. Frank and Neurath made the weaker claim that Nietzsche contributed to the development of a positivistic or scientific conception of the world. Schlick and Frank took a further step in seeing the mature Nietzsche as an Enlightenment thinker. (shrink)

This book grew out of an international symposium, organized in September 1986 by the Austrian Cultural Institute in Warsaw in cooperation with the Polish Philosophical Society. The topic was: The Vienna Circle and the Lvov-Warsaw School. Since the two phil osophical trends existed in roughly the same time and were close ly related, it was one of the purposes of the symposium to investigate both similarities and thp differences. Some thirty people took part in the symposium, nearly twenty (...) contributions were presented and extensively discussed. The sym posium owed much to the excellent organization and warm hospital ity shown by Dr Georg Jankovic, the Director of the Austrian In stitute. As the person in charge of the scientific programme of the symposium, I take pleasure to acknowledge this debt. It so happened that a month later another symposium of a similar character was held. It took place in the University of Manchester, on the occasion of the centenary of the births of Stanislaw Lesniewski, Tadeusz Kotarbiflski and Wladyslaw Tatarkie wicz. Some papers read at the Manchester symposium form a part of the present volume. It was not possible, for technical reasons (the time factor was one of them), to include in this book all the material from the two symposia. Certain contributions have appeared elsewhere (for instance, K. Szaniawski's 'Ajdukiewicz on Non-Deductive Inference' was published in Danish Yearbook of Philosophy, Vol. 23). On the other hand, certain papers have been written special ly for this volume. (shrink)

This abridged and revised edition of the original book (Springer-Verlag Vienna, 2001) offers the only comprehensive history and documentation of the Vienna Circle based on new sources with an innovative historiographical approach to the study of science. With reference to previously unpublished archival material and more recent literature, it refutes a number of widespread clichés about "neo-positivism" or "logical positivism". Following some insights on the relation between the history of science and the philosophy of science, the book (...) offers an accessible introduction to the complex subject of "the rise of scientific philosophy" in its socio-cultural background and European philosophical networks till the forced migration in the Anglo-Saxon world. The first part of the book focuses on the origins of Logical Empiricism before World War I and the development of the Vienna Circle in "Red Vienna" (with the "Verein Ernst Mach"), its fate during Austro-Fascism (Schlick's murder 1936) and its final expulsion by National-Socialism beginning with the "Anschluss" in 1938. It analyses the dynamics of the Schlick-Circle in the intellectual context of "late enlightenment" including the minutes of the meetings from 1930 on for the first time published and presents an extensive description of the meetings and international Unity of Science conferences between 1929 and 1941. The chapters introduce the leading philosophers of the Schlick Circle (e.g., Hans Hahn, Otto Neurath, Rudolf Carnap, Philipp Frank, Felix Kaufmann, Edgar Zilsel) and describe the conflicting interaction between Moritz Schlick and Otto Neurath, the long term communication between Moritz Schlick, Friedrich Waismann and Ludwig Wittgenstein, as well as between the Vienna Circle with Heinrich Gomperz and Karl Popper. In addition, Karl Menger's "Mathematical Colloquium" with Kurt Gödel is presented as a parallel movement. The final chapter of this section describes the demise of the Vienna Circle and the forced exodus of scientists and intellectuals from Austria.The second part of the book includes a bio-bibliographical documentation of the Vienna Circle members and for the first time of the assassination of Moritz Schlick in 1936, followed by an appendix comprising an extensive list of sources and literature.

The history of early analytic philosophy, and especially the work of the logical empiricists, has often been seen as involving antagonisms with rival schools. Though recent scholarship has interrogated the Vienna Circle’s relations with e.g. phenomenology and Neo-Kantianism, important works by some of its leading members are involved in responding to the rising tide of Lebensphilosophie. This paper will explore Carnap’s configuration of the relation between Lebensphilosophie and the overcoming of metaphysics, Schlick’s responses to Schopenhauer and Nietzsche, and (...) Neurath’s reaction against Spengler. (shrink)

The Vienna Circle was an influential group of philosophers in the early 20th century. Its members were dedicated to do philosophy and to conduct research in accordance with the guidelines of the scientific world-conception. For some of them, Oswald Spengler was a dangerous antagonist due to the success and influence of his metaphysical philosophy of history in Der Untergang des Abendlandes and other works. In this paper, I will explore systematically the Circle’s critical reception of Spengler regarding (...) his methodological approaches, ontological positions, and political philosophy. I will, thereby, also evaluate the criticism brought forth against Spengler. (shrink)

The Uppsala School in philosophy and the Vienna Circle are prima facie similar currents in contemporary philosophy. Both reject metaphysics, claim that reality is a spatio­‑temporal realm and adhere to noncognitivism in terms of values. However, justifications of these assumptions are quite different. In the following article we reconstruct main theses of both mentioned currents and then we indicate their impact on one of the major jurisprudential movements, namely Scandinavian Legal Realism. We focus on Alf Ross’ legal philosophy, (...) as it was an attempt to accommodate both: the philosophy of the Uppsala School and of the Vienna Circle. We trace those two sources of inspiration in Ross’ theory of legal validity and of legal concepts. (shrink)

Uebel has recently claimed that, contrary to popular opinion, none of the philosophers of the Vienna Circle of Logical Positivists were proponents of epistemological foundationalism. According to the considerations of the current discussion, however, Uebel's conclusion is erroneous, especially with respect to the work of Moritz Schlick. The chief reason Uebel offers to support his conclusion is that current attempts to portray Schlick's epistemology as foundationalist fail to overcome its ‘ultimate incoherence’. In contrast, it is argued that current (...) interpretations, based on the unpublished as well as the published record, provide understandings of Schlick's foundationalist epistemology as not only coherent, but plausible. In closing, Uebel's own treatment of Schlick's work, which purports to show that the most feasible candidates for foundational statements are ‘meaning-theoretic’ clarifications of the content of expressions, itself fails to accurately represent Schlick's own characterizations, and pictures Schlick's epistemology as a confused mix of epistemic and semantic insights.

This work is for scholars, researchers and students in history and philosophy of science focusing on Logical Empiricism and analytic philosophy (of science). It provides historical and systematic research and deals with the influence and impact of the Vienna Circle/Logical Empiricism on today's philosophy of science. It also explores the intellectual context of this scientific philosophy and focuses on main figures and peripheral adherents.

The article examines the main ideological content of the work of the community of scientists and philosophers, which entered the history of philosophy under the name “The Vienna Circle”. Representatives of this association viewed their main methodological task in the logical analysis of the language of science in order to eliminate metaphysical – pseudoscientific – concepts. They investigated the structure of scientific theories, the functions of the theory – explanation and prediction, the processes of justification, confirmation and refutation (...) of theories. Their results were widely recognized, set down essential influence on scientific problems as well as style of philosophical and academic studies, and are still included in textbooks on the philosophy of science. The members of the Vienna Circle created the first holistic concept of science, which gave impetus to subsequent developments in the philosophy of science and served as example for the construction of similar concepts. The socio-ideological prerequisite of this philosophical movement was the task of creating a new scientific view of the world, opposing philosophical pessimism and anti-scientism. This worldview, however, was not naive-scientististic, but presented a synthetic project at the intersection of natural science, philosophy, art and social pedagogy. (shrink)

Members of Vienna Circle explicated determinism in terms of predictability in principle, or calculability. This paper attempts to uncover the rationale for this explication. It argues that the explication was an attempt to escape trivialization arguments; another important factor was the Circle’s views on meaning as testability.

Tscha Hung was a member of the Vienna Circle who achieved high international academic recognition. He dedicated his entire life to spreading the philosophy of the Circle to China and developed deep insights in his criticisms to that philosophy. Hung was a witness to the encounter of Western and Chinese philosophy in the twentieth century. His debate with Fung You-lan on metaphysics reflects different understandings of the nature of philosophy and metaphysics as well as different perspectives. Hung (...) defended the position of metaphysics in Chinese philosophy in his own way and engaged in a contemporary reconstruction of Chinese philosophy. (shrink)

The theory of quantum mechanics has often been thought to show an affinity with logical empiricism: in both, observation plays a central role, and questions about what is unobservable are dismissed. However, there were also strong tensions between the logical empiricism of the Vienna Circle and implications drawn from quantum physics. In the 1920s and 1930s, many physicists thought that quantum mechanics revealed a limit to what could be known scientifically, and this opened the door to a wide (...) range of speculations, in which quantum mechanics was connected with free will, organic life, psychology, and religion—speculations in which many leading quantum physicists were engaged. Members of the Vienna Circle, such as Frank and Schlick, looked at quantum mechanics for a confirmation of their empiricist views, but they were at the same time critical about these wider implications drawn from quantum mechanics, which in their eyes were connected with broader mystical and irrational trends in society. They engaged in particular with the views of Bohr and Jordan, both of whom expressed a sympathy for logical empiricism while at the same time arguing for claims that proved hard to reconcile with the scientific world conception of the Vienna Circle.

In 1980, Pierre Jacob1 published a book about the itinerary of logical positivism from Vienna to Cambridge , a story of the migration and of the effects of logical positivism in America since the fifties. Christiane Chauviré 2 took the other way round in a paper about the early influence of Peirce’s pragmatism on the Vienna Circle . We are also aware of the importance of logical positivism in England. Sir Alfred Ayer brought it back to England (...) after having met, on Ryle’s recommendation, Moritz Schlick in Vienna in 1932. Gilbert Ryle was Ayer’s tutor in Oxford. The meeting between the two of them took place two years after the International Congress of Philosophy in Oxford . It was on this occasion that Gilbert Ryle, who opened the congress, met Schlick for the first time. In his autobiographical sketch,3 he mentions the impact of the Viennese philosophy on his own philosophical development in the early thirties. This attests to the Vienna/Cambridge /Oxford triangle.

This book provides a new all-round perspective on the life and work of Edgar Zilsel (1891-1944) as a philosopher, historian, and sociologist. He was close to the Vienna Circle and has been hitherto almost exclusively referred to in terms of the so-called “Zilsel thesis” on the origins of modern science. Much beyond this “thesis”, Zilsel’s brilliant work provides original insights on a broad number of topics, ranging from the philosophy of probability and statistics to the concept of “genius”, (...) from the issues of scientific laws and theories to the sociological background of science and philosophy, and to the political analysis of the problems of his time. Praised by Herbert Feigl as an “outstanding brilliant mind”, Zilsel, being as a Social-Democrat of Jewish origins, mostly led a life of hardship marked by emigration and coming to a sudden and tragic end by suicide in 1944. The impossibility of an academic career has hindered the reception of Zilsel’s scientific work for a long time. This volume is a contribution to its late reception, providing new insights especially into his work during his years in Vienna; moreover, it shows the heuristic value of Zilsel’s ideas for future Scholar research – in philosophy, history, and sociology. -/- (ISSN: 0929-6328).

Recent scholarship resuscitates the history and philosophy of a ‘left wing’ in the Vienna Circle, offering a counterhistory to the conventional image of analytic philosophy as politically conformist. This paper disputes the historical claim that early logical empiricists developed a political philosophy of science. Though some individuals in the Vienna Circle, including Rudolf Carnap and Otto Neurath, believed strongly in the importance of science to social progress, they did not construct a political philosophy of science. Both (...) Carnap and Neurath were committed to forms of political neutralism that run strongly against a political reading of their logical empiricism. In addition, Carnap and Neurath sharply differ on precisely the subject of the place of politics in logical empiricism, throwing into question the construct of the ‘Left Vienna Circle’ as a coherent, sociohistorical, programmatic unit within the Vienna Circle.Keywords: Vienna Circle; Rudolf Carnap; Otto Neurath; Logical empiricism; History of philosophy of science; Political philosophy of science.

A new direction in philosophy Between 1920 and 1940 logical empiricism reset the direction of philosophy of science and much of the rest of Anglo-American philosophy. It began as a relatively organized movement centered on the Vienna Circle, and like-minded philosophers elsewhere, especially in Berlin. As Europe drifted into the Nazi era, several important figures, especially Carnap and Neurath, also found common ground in their liberal politics and radical social agenda. Together, the logical empiricists set out to reform (...) traditional philosophy with a new set of doctrines more firmly grounded in logic and science. Criticism and decline Because of Nazi persecution, most of the European adherents of logical empiricism moved to the United States in the late 1930s. During the 1940s, many of their most cherished tenets became targets of criticism from outsiders as well as from within their own ranks. Philosophers of science in the late 1950s and 1960s rejected logical empiricism and, starting in the 1970s, presented such alternative programs such as scientific realism with evolutionary epistemology. A resurgence of interest During the early 1980s, philosophers and historians of philosophy began to study logical empiricism as an important movement. Unlike their predecessors in the 1960s-for whom the debate over logical empiricism now seems to have been largely motivated by professional politics-these philosopher no longer have to take positions for or against logical empiricism. The result has been a more balanced view of that movement, its achievements, its failures, and its influence. Hard-to-find core writings now available This collection makes available a selection of the most influential and representative writings of the logical empiricists, important contemporary criticisms of their doctrines, their responses, as well as the recent reappraisals.

This paper analyzes the claim that the Left Vienna Circle offers a theoretical and historical precedent for a politically engaged philosophy of science today. I describe the model for a political philosophy of science advanced by LVC historians. They offer this model as a moderate, properly philosophical approach to political philosophy of science that is rooted in the analytic tradition. This disciplinary-historical framing leads to weaknesses in LVC scholars’ conception of the history of the LVC and its contemporary (...) relevance. In this light, I examine the claim that there are productive enrichments to be gained from the engagement of feminist philosophy of science with the LVC, finding this claim ill-formulated. The case of LVC historiography and feminist philosophy of science presents a revealing study in the uses and ethics of disciplinary history, showing how feminist and other perspectives are misconceived and marginalized by forms of disciplinary self-narrativizing.Keywords: Vienna Circle; Logical empiricism; Political philosophy of science; Disciplinary history; Feminist philosophy of science.

The larger part of Yearbook 6 of the Institute Vienna Circle constitutes the proceedings of a symposium on Alfred Tarski and his influence on and interchanges with the Vienna Circle, especially those on and with Rudolf Carnap and Kurt Gödel. It is the first time that this topic has been treated on such a scale and in such depth. Attention is mainly paid to the origins, development and subsequent role of Tarski's definition of truth. Some contributions (...) are primarily historical, others analyze logical aspects of the concept of truth. Contributors include Anita and Saul Feferman, Jan Wolenski, Jan Tarski and Hans Sluga. Several Polish logicians contributed: Gzegorczyk, Wójcicki, Murawski and Rojszczak. The volume presents entirely new biographical material on Tarski, both from his Polish period and on his influential career in the United States: at Harvard, in Princeton, at Hunter, and at the University of California at Berkeley. The high point of the analysis involves Tarski's influence on Carnap's evolution from a narrow syntactical view of language, to the ontologically more sophisticated but more controversial semantical view. Another highlight involves the interchange between Tarski and Gödel on the connection between truth and proof and on the nature of metalanguages. The concluding part of Yearbook 6 includes documentation, book reviews and a summary of current activities of the Institute Vienna Circle. Jan Tarski introduces letters written by his father to Gödel; Paolo Parrini reports on the Vienna Circle's influence in Italy; several reviews cover recent books on logical empiricism, on Gödel, on cosmology, on holistic approaches in Germany, and on Mauthner.
