Logical Empiricism

Syntactic approaches in the philosophy of science, which are based on formalizations in predicate logic, are often considered in principle inferior to semantic approaches, which are based on formalizations with the help of structures. To compare the two kinds of approach, I identify some ambiguities in common semantic accounts and explicate the concept of a structure in a way that avoids hidden references to a specific vocabulary. From there, I argue that contrary to common opinion (i) unintended models do not (...) pose a significant problem for syntactic approaches to scientific theories, (ii) syntactic approaches can be at least as language-independent as semantic ones, and (iii) in syntactic approaches, scientific theories can be as well connected to the world as in semantic ones. Based on these results, I argue that syntactic and semantic approaches fare equally well when it comes to (iv) ease of application, (v) accommodating the use of models in the sciences, and (vi) capturing the theory-observation relation.

A brief review of Carnap's formal program in philosophy of science.

Carnaps Denken wurde während seines Studiums und der Arbeit an seiner Dissertation von Neukatianischen Motiven beeinflusst, von denen er sich nach seiner Habilitation in Wien (1926) zunehmend distanzierte. Er besuchte in Freiburg bei Heinrich Rickert (1911/1912) und in Jena (1913/14) bei Bruno Bauch Lehrveranstaltungen zur Philosophie. Außerdem besuchte er in Freiburg bei Jonas Cohn Lehrveranstaltungen zur experimentellen Psychologie. Bei Bauch reichte er 1920 eine Arbeit mit dem Titel Welche philosophische Bedeutung hat das Problem der „Grundlegung der Geometrie“ für die Lehramtsprüfung (...) und 1921 seine darauf aufbauende Dissertation Der Raum. Ein Beitrag zur Wissenschaftslehre ein. Rickert war das Haupt der von Wilhelm Windelband begründeten Südwestdeutschen Schule des Neukantianismus, zu der auch Cohn und Bauch gezählt werden. Bauch war jedoch auch von der von Hermann Cohen begründeten Marburger Schule des Neukantianismus, deren herausragenste Vertreter Paul Natorp und Ernst Cassirer sind, beeinflusst. Vor allem Natorps Die logischen Grundlagen der exakten Wissenschaften (1910a) und Cassirers Substanzbegriff und Funktionsbegriff (1910) beeinflussten Carnaps Verständnis der methodischen Grundlagen der Mathematik und der Physik (Richardson 1998, 115-117, 138-139; Mormann 2000, 44-46). In persönlichem Kontakt war Carnap seit seinem Umzug nach Buchenbach Anfang der 1920er Jahre auch mit dem Rickert-Schüler Broder Christiansen. (shrink)

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).

Logical positivism is often characterized as a set of naïve doctrines on meaning, method, and metaphysics. In recent decades, however, historians have dismissed this view as a gross misinterpretation. This new scholarship raises a number of questions. When did the standard reading emerge? Why did it become so popular? And how could commentators have been so wrong? This paper reconstructs the history of a ‘caricature’ and rejects the hypothesis that it was developed by ill-informed Anglophone scholars who failed to appreciate (...) the subtleties of European scientific philosophy. I argue that the received view has a more complicated history and was frequently promoted by the European positivists themselves. I show that it has roots in both American and European scientific philosophy and emerged as a result of the complex interplay between the two communities in the years before the intellectual migration.

Historians have shown that philosophical discussions about the implications of relativity significantly shaped the development of European philosophy of science in the 1920s. Yet little is known about American debates from this period. This paper maps the first responses to Einstein’s theory in three U.S. philosophy journals and situates these papers within the local intellectual climate. We argue that these discussions (1) stimulated the development of a distinctly American branch of philosophy of science and (2) paved the way for the (...) logical empiricists, who emigrated to the United States in the years before World War II.

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 is an updated version of an essay originally written for a special issue of Philosophical Topics on the links between Kant and analytic philosophy. It explores these links by focusing on: Wittgenstein’s Tractatus; the logical positivism endorsed by Ayer; and the (very different) variation on that theme endorsed by Quine. The claim defended is that in all three cases we see analytic philosophers trying to attain and express a general philosophical understanding of why the bounds of sense should be (...) drawn where they should—but thereby confronting the aporia, which Kant too confronted, that it is impossible to do this without transgressing those very bounds. The paper closes by suggesting that the problem is in trying to attain and express such an understanding; in other words, that such an understanding is attainable, but not expressible. (shrink)

In conversations with Schlick and Waismann from June and December 1930, Wittgenstein began to turn his attention to the topic of games. This topic also centrally concerned Schlick. In his earliest philosophical output, Schlick had relied on the results of evolutionary biology in setting out an account of the emergence of the human species’ ability to play [Spiel] as a prerequisite for the genesis of scientific knowledge. Throughout his subsequent works one finds fragmentary appeals to this early view, e.g. in (...) his oft misunderstood claim that play constitutes the meaning of life. Wittgenstein’s turn to the topic of games in 1930 not only happened while Professor Schlick was in the room, but was also coupled with an explicit response to Schlick’s 1930 book Fragen der Ethik. Schlick here employs the example of chess to distinguish between rules and their application – a distinction which underlies his whole attempt to naturalise ethics as a descriptive psycho-sociological discipline. This paper investigates the relation between Wittgenstein’s and Schlick’s accounts of games in light of Wittgenstein’s criticisms of Schlick’s ethics. Wittgenstein’s objections can be answered by taking Schlick’s theory of play into consideration. (shrink)

In this paper I aim to demonstrate that Rudolf Carnap's analysis of the application of information theory within physics, an intellectual-historical precedent of current philosophical criticisms toward this tendency, is justified. First, Carnap and Bar-Hillel (1952) underlined the unjustified ‘semantification’ of Shannon entropy Furthermore, Carnap criticized the ‘physicalization’ of Shannon entropy, but that criticism was not accepted by the physics community of the 1950s (Köhler 2001). Finally, in the posthumously published "Two Essays on Entropy" Carnap (1977) developed a critical assessment (...) of entropy concepts that showed some deep conceptual and interpretative deficiencies in Jaynes (1957a) and Brillouin’s (1956) informational approaches to thermophysics.

Moritz Schlick, Rudolf Carnap and Herbert Feig are the most prominent of the positivists to formulate views on the mind-body problem (aside from Hempel’s one-off treatment in 1935). While their views differed from each other and changed over time they were all committed to some form of scientific physicalism, though a linguistic or conceptual rather than ontological form of it. In focus here are their views during the heyday of logical positivism and its immediate aftermath, though some initial scene-setting of (...) Schlick’s and Carnap’s pre-positivist views will help to understand the final opposing positions of Carnap and Feigl. (shrink)

This paper contributes to explaining the rise of logical empiricism in mid-twentieth century (North) America and to a better understanding of American philosophy of science before the dominance of logical empiricism. We show that, contrary to a number of existing histories, philosophy of science was already a distinct subfield of philosophy, one with its own approaches and issues, even before logical empiricists arrived in America. It was a form of speculative philosophy with a concern for speculative metaphysics, normative issues relating (...) to science and society and issues which later were associated with logical empiricist philosophy of science, issues such as confirmation, scientific explanation, reductionism and laws of nature. Further, philosophy of science was not primarily pragmatist in orientation. We also show, with the help of our historical characterization, that a recent account of the emergence of analytic philosophy applies to the rise of logical empiricism. It has been argued that the emergence of American analytic philosophy is partly explained by analytic philosophers’ use of key institutions, including of journals, to marginalize speculative philosophy and promote analytic philosophy. We argue that this use of institutions included the marginalization of speculative and value-laden philosophy of science and the promotion of logical empiricism. (shrink)

The global relation between logical empiricism and American pragmatism is one of the more difficult problems in history of philosophy. In this paper I’d like to take a local perspective and concentrate on the details that concern the vicissitudes of a philosopher who played an important role in the encounter of logical empiricism and American pragmatism, namely, Ernest Nagel. In this paper, I want to explore some aspects of Nagel’s changing attitude towards the then „new“ logical-empiricist philosophy. In the beginning (...) Nagel welcomed logical empiricism whole-heartedly. This early enthusiasm did not last. At the end of his philosophical career Nagel’s early positive attitude towards logical empiricism shown in the 1930s had been replaced by a much more reserved one. Nagel’s growing dissatisfaction with the Carnapian version of logical empiricist philosophy was clearly expressed in Nagel’s criticism of Carnap’s inductive logic and more generally in his last book Teleology Revisited and Other Essays on History and Philosophy of Science. There he critized harshly Carnap’s philosophy of science in general as ahistoric and non-pragmatist. One of the distinctive features of Nagel’s philosophy of science is the emphasis that he put on the role of history of science for philosophy of science. A compelling evidence for this attitude are his works on the history and philosophy of geometry and algebra One may say that Carnap and Nagel represented opposed possibilities of how the profession of a philosopher of science could be understood: Carnap as a „conceptual engineer“ was engaged in the task of inventing the conceptual tools for a better theoretical understanding of science, while Nagel was to be considered more as a „public intellectual“ engaged in the project of realizing a more rational and enlightened society.

With the outbreak of the First World War in 1914, there emerged two controversies related to the responsibility of philosophical ideas for the rise of German militarism. The first, mainly journalistic, controversy concerned the influence that Nietzsche’s ideas may have had on what British propagandists portrayed as the ruthlessly amoral German foreign policy. This soon gave way to a second controversy, waged primarily among academics, concerning the purportedly vicious political outcomes of German Idealism, from Kant through to Fichte, Schelling, and (...) Hegel. During the autumn of 1914, and at the cusp between the two controversies, Moritz Schlick was to deliver a lecture series on Nietzsche’s life and work at the University of Rostock. Responding to both debates, Schlick penned an introduction in which he sought to defend philosophy against all those who would embroil it in warfare. Schlick offers a series of arguments defending Nietzsche against his accusers. He also argues that, though their contributions to the History of Philosophy often amounted to no more than ‘beautiful nonsense’, the German Idealists’ philosophical views cannot be held responsible for the rise of German nationalism. Finally, Schlick mounts a general defense of the search for truth, both in philosophy and in Wissenschaft, as a type of activity which presupposes peace. Though Schlick’s metaphilosophical views change, as this paper shows, he remains constant both in his favourable appraisal of Nietzsche, as well as his separation between politics on the one hand, and both philosophy and Wissenschaft on the other hand.

During the first quarter of the twentieth century, the French philosopher Henri Bergson became an international celebrity, profoundly influencing contemporary intellectual and artistic currents. While Bergsonism was fashionable, L. Susan Stebbing, Bertrand Russell, Moritz Schlick, and Rudolf Carnap launched different critical attacks against some of Bergson’s views. This book examines this series of critical responses to Bergsonism early in the history of analytic philosophy. Analytic criticisms of Bergsonism were influenced by William James, who saw Bergson as an ‘anti-intellectualist’ ally of (...) American Pragmatism, and Max Scheler, who saw him as a prophet of Lebensphilosophie. Some of the main analytic objections to Bergson are answered in the work of Karin Costelloe-Stephen. Analytic anti-Bergsonism accompanied the earlier refutations of idealism by Russell and Moore, and later influenced the Vienna Circle’s critique of metaphysics. It eventually contributed to the formation of the view that ‘analytic’ philosophy is divided from its ‘continental’ counterpart. (shrink)

During the late 1930s, the failed attempt at collaboration between the Frankfurt School and the Vienna Circle culminated in Horkheimer’s 1937 paper ‘The Latest Attack on Metaphysics’. Horkheimer ([1937] 1972), relying on a caricature of positivism as espousing an uncritical myth of the given, drew far-reaching conclusions concerning positivism’s conservative prohibition of the radical questioning of appearances. Horkheimer (1940) later applied some of these criticisms to Dilthey’s conception of Verstehen, while presenting Logical Empiricism as dismissing Dilthey’s proposals nothing more than (...) poetry. By examining Neurath’s unpublished reply to Horkheimer, and drawing on Uebel’s (2019) account of Logical Empiricism’s stance towards Verstehen, this chapter will attempt to dispel Horkheimer’s caricature. I will highlight a parallel between Neurath’s attitude towards (i) claims about Verstehen in social science and (ii) Horkheimer’s proposals for the use of Vernunft by a ‘supra-scientific’ Critical Theory. Neurath argues that once Horkheimer’s objections to ‘positivism’ are reformulated in non-metaphysical terms, they point towards a genuine problem concerning science’s relation to social praxis. For Neurath, the problem can be addressed from within (rather than, as Horkheimer would have it, from above) empirically-minded investigations in the history and sociology of science. (shrink)

This Open Access volume is based on the 'Early Carnap in Context’ workshop that took place in Konstanz in 2017 and looks at Rudolf Carnap’s philosophy, documented in his recently released diaries, from a combination of historical, cultural and philosophical perspectives. It enables further evaluation of the diaries and traces newly found interrelationships and their systematic definition. From a cultural and historical point of view, Logical Empiricism and Carnap’s pivotal opus, The Logical Structure of the World, did not evolve in (...) a vacuum. This applies equally in a history of philosophy context as well as under consideration of contemporary historical and cultural influences such as the socio-cultural setting in Vienna and Prague, the correlation between Logical Empiricism and Bauhaus modernism, the connection to the Life Reform Movement or the Youth Movement with its own life philosophy. Pursuing Carnap’s progression on a micro level of history and referring the results back to Carnap’s philosophy is now facilitated by recent access to his Diaries from 1908–1935. These shorthand records, reading lists, travel reports and notes constitute a valuable source for the research of networks and social movements which left their mark on him. (shrink)

In this paper, we investigate how the life and work of Louis Rougier relate to the broader political dimension of logical empiricist philosophy. We focus on three practical projects of Rougier in the 1930s and 1940s: first, his attempts to integrate French-speaking philosophers into an international network of scientific philosophers by organizing two Unity of Science conferences in Paris; second, his role in the renewal of liberalism through the organization of the Walter Lippmann Colloquium; and third, his attempts at political (...) negotiations between Great Britain and the Vichy regime during the Second World War. These activities of Rougier in the 1930s and 1940s have so far never been discussed as part of a unified project on his part. Based on our investigations of these practical projects of Rougier, we argue that his relation to logical empiricist philosophers should primarily be understood on the level of action. His projects aimed to proliferate the concrete improvement of society and the lives of its citizens by expunging all metaphysical questions and speculations from the sphere of social discourse. Rougier conceived logical empiricist philosophers as allies to achieve such practical effects in society. (shrink)

The most prominent Czech philosopher, Karel Kosík, makes a few hints to the Vienna Circle, Otto Neurath and "positivism" in his important book, DIALECTICS OF THE CONCRETE (1963). I mine these few remarks for a better understanding of the conflicts, as well as connections, between the social progressivism of the Vienna Circle and the later Marxist humanism.

Hempel seems to hold the following three views: (H1) Understanding is pragmatic/relativistic: Whether one understands why X happened in terms of Explanation E depends on one's beliefs and cognitive abilities; (H2) Whether a scientific explanation is good, just like whether a mathematical proof is good, is a nonpragmatic and objective issue independent of the beliefs or cognitive abilities of individuals; (H3) The goal of scientific explanation is understanding: A good scientific explanation is the one that provides understanding. Apparently, H1, H2, (...) and H3 cannot be all true. Some philosophers think that Hempel is inconsistent, while some others claim that Hempel does not actually hold H3. I argue that Hempel does hold H3 and that he can consistently hold all of H1, H2, and H3 if he endorses what I call the “understanding argument.” I also show how attributing the understanding argument to Hempel can make more sense of his D-N model and his philosophical analysis of the pragmatic aspects of scientific explanation.

Our main goal in this paper is to present and scrutinize Reichenbach’s own naturalism in our contemporary context, with special attention to competing versions of the concept. By exploring the idea of Reichenbach’s naturalism, we will argue that he defended a liberating, therapeutic form of naturalism, meaning that he took scientific philosophy to be a possible cure for bad old habits and traditional ways of philosophy. For Reichenbach, naturalistic scientific philosophy was a well-established form of liberation. We do not intend (...) to suggest that Reichenbach acted as an inventor of naturalism; nonetheless, invoking the term and the idea of ‘naturalism’ is more than a simple rhetorical strategy for rehabilitating Reichenbach as a forerunner of this field. We think that his ideas can make a valuable contribution to contemporary debates, and that he presents an interesting case among the other scientifically oriented proponents of his time. After presenting a short reconstruction of the meaning of naturalism—or, more appropriately, naturalisms—in order to be able to correctly situate Reichenbach within his own as well as a systematic context, we discuss Reichenbach’s naturalism against the background of his scientific philosophy, his views on the relation of common-sense knowledge to science, and his efforts at popularization. To delve deeper into this topic, we present a case study to show how Reichenbach argued that in both scientific and philosophical discussions, it is necessary to move from the request and value of truth to probability. And, finally, we argue that the liberation of knowledge and nature was a socio-political program for Reichenbach, who talked about his own scientific philosophy as “a crusade.” By emphasizing this aspect of Reichenbach’s naturalism, we may be in a better position to situate him in the history of analytic philosophy in general, and in the yet-to-be-written narrative of the naturalistic movement in particular.

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.

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.

The received view on the development of the correspondence rules in Carnap’s philosophy of science is that at first, Carnap assumed the explicit definability of all theoretical terms in observational terms and later weakened this assumption. In the end, he conjectured that all observational terms can be explicitly defined in in theoretical terms, but not vice versa. I argue that from the very beginning, Carnap implicitly held this last view, albeit at times in contradiction to his professed position. To establish (...) this point I argue that, first, Carnap’s ‘Über die Aufgabe der Physik’ is a contribution to the philosophy of science of logical empiricism, contrary to Thomas Mormann and in agreement with Herbert Feigl. Second, Michael Friedman misunderstands the ‘Aufgabe’ with his claim that it describes a method for arriving at explicit definitions for theoretical terms. Another received view on Carnap’s philosophy of science is that it assumed a formalization of physical theories that was too detached from actual physics and thus justly disavowed in favor of the semantic view as, for example, developed by van Fraassen. But the ‘Aufgabe’ and related works including the Aufbau show that from the very beginning to his last works, Carnap suggested formalizing physical theories as restrictions in mathematical spaces, as in the state-space conception of scientific theories favored by van Fraassen.

This volume has two primary aims: to trace the traditions and changes in methods, concepts, and ideas that brought forth the logical empiricists’ philosophy of physics and to present and analyze the logical empiricists’ various and occasionally contrary ideas about the physical sciences and their philosophical relevance. These original chapters discuss these developments in their original contexts and social and institutional environments, thus showing the various fruitful conceptions and philosophies behind the history of 20th-century philosophy of science. Logical Empiricism and (...) the Natural Sciences is divided into three thematic sections. Part I surveys the influences on logical empiricism’s philosophy of science and physics. It features chapters on Maxwell’s role in the worldview of logical empiricism, on Reichenbach’s account of objectivity, on the impact of Poincaré on Neurath’s early views on scientific method, Frank’s exchanges with Einstein about philosophy of physics, and on the forgotten role of Kurt Grelling. Part II focuses on specific physical theories, including Carnap’s and Reichenbach’s positions on Einstein’s theory of general relativity, Reichenbach’s critique of unified field theory, and the logical empiricists’ reactions to quantum mechanics. The third and final group of chapters widens the scope to philosophy of science and physics in general. It includes contributions on von Mises’ frequentism; Frank’s account of concept formation and confirmation; and the interrelations between Nagel’s, Feigl’s, and Hempel’s versions of logical empiricism.

In the late 1920s and early 1930s, the philosopher Hans Reichenbach led a group of like-minded colleagues in Berlin that must count as an independent point of origin of the movement of logical empiricism. Like the Vienna Circle with whom they cooperated on numerous occasions, their concern was to develop a philosophy of science adequate to the latest advances in science itself. Differences of philosophical background and interests, however, resulted in putting different accents by justifying scientific knowledge.

The aim of this paper is to show that a comprehensive account of the role of representations in science should reconsider some neglected theses of the classical philosophy of science proposed in the first decades of the 20th century. More precisely, it is argued that the accounts of Helmholtz and Hertz may be taken as prototypes of representational accounts in which structure preservation plays an essential role. Following Reichenbach, structure-preserving representations provide a useful device for formulating an up-to-date version of (...) a (relativized) Kantian a priori. An essential feature of modern scientific representations is their mathematical character. That is, representations can be conceived as (partially) structure-preserving maps or functions. This observation suggests an interesting but neglected perspective on the history and philosophy of this concept, namely, that structure-preserving representations are closely related to a priori elements of scientific knowledge. Reichenbach’s early theory of a relativized constitutive but non-apodictic a priori component of scientific knowledge provides a further elaboration of Kantian aspects of scientific representation. To cope with the dynamic aspects of the evolution of scientific knowledge, Cassirer proposed a re-interpretation of the concept of representation that conceived of a particular representation as only one phase in a continuous process determined by pragmatic considerations. Pragmatic aspects of representations are further elaborated in the classical account of C.I. Lewis and the more modern of Hasok Chang. (shrink)

Most accounts of “logical empiricism in America” take logical empiricism to be a monolithic, or at least a one-dimensional, philosophical group. This picture of logical empiricism has come under well-reasoned attack during the past two decades, but some of the relevant conclusions for the reception-history of the movement were not drawn, or were not drawn as thoroughly as they could have been. Thus, if we want to understand the reception of logical empiricism, we should not talk about the reception of (...) logical empiricism as such; rather, we should provide a more stratified and differently balanced account. This article aims to draw the contours of one more stratified account by pointing out differences in the reception-history of logical empiricism with respect to pragmatism in particular. Namely, I will examine and defend an account according to which the more pragmatist-naturalist wing of logical empiricism was welcomed by the majority of American pragmatists while the more technical wing came immediately under pragmatist attack from various sides.

Ernest Nagel played a key role in bridging the gap between American philosophy and logical empiricism. He introduced European philosophy of science to the American philosophical community but also remained faithful to the naturalism of his teachers. This paper aims to shed new light on Nagel’s intermediating endeavors by reconstructing his philosophical development in the late 1920s and 1930s. This is a decisive period in Nagel’s career because it is the phase in which he first formulated the principles of his (...) naturalism and spent a year in Europe to visit the key centers of logical empiricism. Building on a range of published and unpublished papers, notes, and correspondence—including hundreds of pages of letters to his close friend Sidney Hook—I reconstruct Nagel’s philosophical development, focusing especially on the philosophical influence of John Dewey, Morris R. Cohen, Rudolf Carnap, and Hans Reichenbach. (shrink)

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.

In his earliest philosophical work, Moritz Schlick developed a proposal for rendering aesthetics into a field of empirical science. His 1908 book Lebensweisheit developed an evolutionary account of the emergence of both scientific knowledge and aesthetic feelings from play. This constitutes the framework of Schlick’s evolutionary psychological methodology for examining the origins of the aesthetic feeling of the beautiful he proposed in 1909. He defends his methodology by objecting to both experimental psychological and Darwinian reductionist accounts of aesthetics. Having countered (...) these approaches, Schlick applies Külpe’s psychological distinction between stimulus-feelings and idea-feelings to collapse the traditional philosophical opposition between the agreeable and the beautiful. Both types of feeling, Schlick argues, result from humans’ adaptation to their environment. Because of this adaptation, feelings that were once only stimuli for action can come to be enjoyed for their own sake. This thesis underlies Schlick’s 1908 argument that art, qua mimesis, is necessarily inferior to aesthetic feelings directed towards the environment. Part of Schlick’s justification for this view is that humans are, through a long evolutionary process, better adapted to their environment than to artworks. Schlick nevertheless concedes that mimetic art can involve ways of abstracting from the objects it copies to produce idealised regularities that are not found in the original. Schlick thus concludes that art teaches its audience how to perceive the world in this abstract and idealised manner. This type of environmental aesthetics constitutes a means for reaching Schlick’s utopian ecological vision of a future in which culture will become harmonised with nature. (shrink)

Carnap’s 1931 attack against metaphysics notoriously utilises Heidegger’s work to exemplify the meaninglessness of metaphysical pseudo‐statements. This paper interprets Carnap’s metametaphysics as concerned with delimiting theoretical dialogue in such a manner as to exclude unresolvable disagreements. It puts forth a revised version of Carnap’s argument against the viability of metaphysics, by setting aside his stronger claims that rely on verificationism and focusing instead on his account of metaphysical claims as mere expressions of what he calls “Lebensgefühl,” or a general attitude (...) towards life. Such attitudes, Carnap argues, are unsuitable objects of theoretical dialogue, insofar as disagreements that concern them are unresolvable. Carnap thus recommends abandoning the attempt to resolve metaphysical disagreements as if they were theoretical. As long as it does not enter into unresolvable disagreements, art, rather than theory, is the appropriate medium for expressing Lebensgefühl. (shrink)

The concepts of work, labour, leisure, and play have been widely debated by the social sciences. By contrast, most canonical figures in the history of analytic philosophy have written very little, if anything, on the topic. One of the few exceptional discussions of the concept of labour and its history can be found in Bertrand Russell’s popular work from the 1930s, and more specifically his well-known essay ‘In Praise of Idleness’. In the essay, Russell attempts a spirited defence of a (...) specific, qualified proposal for eventual reform: the universal limitation of the working day to four hours. Looming in the background of this proposal is a bolder thesis, namely the view that social progress involves the eventual minimisation (if not the complete elimination) of labour in the sphere of human activity. It is this bolder view that, as I shall show in what follows, Russell at least partly shares with another philosopher whose work shaped the history of analytic philosophy, Moritz Schlick. While Russell's work on the future of leisure and labour was written for a popular audience and widely read, Schlick’s early writings on work and play have not received adequate scholarly attention. Aside from some differences in their scope and details, there are some striking parallels between Russell’s and Schlick’s overall views on the future of work and play. (shrink)

Thomas Kuhn was never a player in the contemporary realism/anti-realism debates, the debate that gained momentum around 1980 or so, with the publication of Bas van Fraassen’s Scientific Image and Larry Laudan’s “Confutation of Convergent Realism”. But I argue that Kuhn had a significant influence on these debates. Kuhn played a significant role in focusing philosophers’ attention on a different issue than the focus of the realism/anti-realism debate of the 1950s and 1960s. Instead of focusing on the meaning of theoretical (...) terms, philosophers of science turned their attention to the problems raised by changes of theory. The particular shape of the contemporary debate thus owes something to the publication of Structure of Scientific Revolutions. (shrink)

Bilimi ve bilimsel bilgiyi kültür, değer ve öznel yargılardan izole ederek nesnel bir şekilde ortaya koyabilmeye yönelik hararetli tartışmaların yaşandığı yirminci yüzyıl bilim anlayışının temel gayesi, deney ve gözleme tabi olabilecek fiziki dünyadaki olguları, mantıksal çözümlemeye tabi tutarak birleştirilmiş bilime ulaşmaktır. Bu amaca giden yolda olgulara dayanmayan ve sınanamayan her türlü metafizik öge yok sayılır. Bilimsel bilginin sadece deney ve gözleme tabi olana, diğer bir deyişle olgu verilerine dayandığı iddiasını taşıyan bu düşünce sistemi, özellikle Viyana Çevresi üyeleri tarafından benimsenmiştir. Bu (...) bakımdan Çevre üyelerinin bilimsellik anlayışındaki temel ölçüt olgulara dayanan önermelerin ya da yargıların doğrulanabilmesidir. Bilimsel bilginin sadece olgusal dünyanın gözlemlenmesi ve bu gözlem sonucunda ortaya konulan önermelerin ya da ifadelerin doğrulanmasıyla sağlandığını düşünen Çevre üyelerinin bu savlarındaki amacı bilimi ve onun bilgisini her türlü kültür ve değer alanından uzaklaştırarak metafiziksel unsurlardan arındırılmış nesnel bilgiye ulaşmaktır. Çevre üyelerinin birçoğu bilim alanı içerisinde tartışmaya yol açan meselelerin aslında metafiziksel içerikli ve dolayısıyla bunların görünüşte problemler olduğunu belirterek bu tartışmaların bilimsel bilginin gelişimi önünde bir engel oluşturacağı kanaatindedir (Hızır, 1965, s. 254). Söz gelimi, Carnap’a göre, metafizik ögeler olgusal içeriğe sahip olmadığı ve sınanabilir nitelikte olmadıkları için bilim alanı içerisinde değerlendirilemez. Bu nedenle, metafizik ögeler hem doğrulanması mümkün olmadığı hem de dilin mantıksal dizimine genellikle uymadığı gerekçesiyle anlamsızdır (Öztürk, 2011, s. 155). Bu bakımdan Çevre üyelerine göre, olgulara dayanmayan ve bilimde yanılsamalara yol açan metafizik söylemler bilimden ayıklanmalı ve bilimsel bilgi ancak olgu ve deneye dayanan önermeler üzerinden yürütülmelidir. Öte yandan Çevre düşünürleri mantıksal çözümleme yoluyla olgulara dayanan önermelerin metafiziksel unsurlar içeren önermelerden ayırt edilebileceğini ifade etmiştir. Bu bağlamda metafizik önermeleri, metafizik olmayan önermelerden ayırt edecek ölçütün doğrulanabilirlik olduğunu savunurlar. Çevre üyelerinin bu tutumları bir bakıma bilim ve sözde bilim arasında ayrım yapma ve metafiziği bilimin dışında tutma çabası olarak da değerlendirilebilir (Kabadayı, 2011, s. 39-40). Yirminci yüzyıl bilim anlayışında bilimsel etkinlikte gözlemin ve gözlemi yürüten bilim insanlarının dolaysız öznel duyu verileriyle ilişkili olduğu bu nedenle gözlem verilerinin psikolojizmin etkisinde olduğu fikri ortaya atılır. Başta Neurath olmak üzere dönemin bilim felsefecileri bilimsel bilginin kültür, değer ve psikoloji gibi öznel unsurlardan uzaklaştığı sürece değerli olduğu kanısında olduğu için bu fikre karşı çıkmaktadır (Gillies, 2018, s. 123). Görüldüğü üzere, Çevre üyelerinin temel amacı metafizik önermelerden arındırılmış, olgulara dayanan bir bilime ulaşmaktır. Bu amacın gerçekleşmesine olanak sağlayacak yöntem ise mantıksal çözümlemedir. Bu bağlamda Çevre üyeleri olgulara dayanan ve doğrulanabilen önermelerin, söz dizimi (sentaks) ve anlamsal (semantik) açıdan incelemeye tabi tutulması gerektiğini düşünmektedir (Yardımcı, 2018, s. 13-15). Özellikle Carnap (1935, s. 9-10) doğrulamanın ancak öne sürülen önermenin mantıksal analize tabi tutularak yapılması gerektiğini iddia etmiştir (Irzık, 1962, s. 65). Bununla birlikte, felsefenin işlevi, önermeleri mantıksal analize tabi tutarak yalın hale getirmektir. İşte felsefenin bu yönü Neurath’da bilimin birliği, Carnap’ta ise bilimin sentaksı, yani bilimin mantığı üzerine çalışma anlamına gelir (Hızır, 1965, s. 252). Bilimi, bilim olmayandan ayırma yöntemi olarak kullanılan doğrulama işlemi, teorik bir söylem ve gözlem önermesi arasında yapılan bir işlem olması bakımından mantıksal ve dilsel bir özellik taşır. Buradaki temel sorun ise teorik bir önermenin gözlem önermelerine indirgenebilir nitelikte olması ve gözlem önermelerinin, gözlem ile nasıl ilişki kurduğunu saptamaktır. İşte Viyana Çevresi üyeleri bu ilişkinin protokol önermeleri ile kurulduğu kanaatindedir (Ural, 2012, s. 105-107) çünkü onlara göre; öznelerarası bir bilimin sağlanması için yansız ve anlam karmaşasından arındırılmış bir dil gereklidir (Serin, 2015, s. 55). Bu dil de ancak protokol önermeler aracılığıyla kurulabilir. Bu bağlamda Çevre üyelerinin, metafiziksel ifadeler barındıran önermelerin anlamsızlığı ve bilimleri ortak bir paydada birleştiren fiziksel bir dil oluşturma olmak üzere iki temel hedefinin olduğu söylenebilir (Godfrey-Smith, 2003, s. 25; Salgar, 2012, s. 187).

The aim of this paper is to investigate the relations between knowledge, language and communication within the framework of Neurath's philosophical and political program. In particular, we draw a parallel between the adoption of the physicalist language as the basic language of science and the development of ISOTYPE system of visual education. We defend the idea that they maintain a relation of reciprocity with each other that makes possible the exchange of factual information and the transformation of verbal statements into (...) visual statements, and vice versa. This relation of reciprocity is also based on a series of shared features. In this regard, we consider that both are conceived as thing-languages and both play a pedagogical and political role, that consists in enabling communication between science and society. For Neurath, this role also involves a model of communication aimed at the humanization of knowledge and the democratization of decisions. (shrink)

In this paper I investigate how intellectual problems concerning an epistemology of history and a historical view of knowledge played a role in the network of logical empiricist philosophers between 1930 and 1945. Specifically, I focus on the practical efforts of Hans Reichenbach and Otto Neurath to incorporate these intellectual stakes concerning history. I argue that Reichenbach was mainly concerned with creating more institutional space for scientific philosophy. Consequently, he was interested in determining his relation to historically oriented philosophy on (...) the practical level only. Otto Neurath, I claim, was interested in promoting an intellectual incorporation of an epistemology of history and a historical view of knowledge into the Unity of Science movement. His attempts, however, largely failed. I conclude that the intellectual stakes concerning history did have an effect within the network of logical empiricist philosophers, but that, by 1945 these stakes were entirely dissolved. The displacement of the network to the United States removed Reichenbach’s practical problems, while Neurath was unable to persuade enough actors before his death. (shrink)

While the Vienna Circle had virtually no impact on the Czech-speaking philosophical community during the 1930s, one can find a curious meeting point in the field of theory of architecture. There is now a growing literature on Otto Neurath as a theorist of architecture and urbanism, who emphasized the social aspects of modern building and approached architecture from his idiosyncratic viewpoint of Marxism interpreted as a physicalistic social science. It is less well known that a young Czech architecture critic and (...) theorist, Karel Teige, cultivated strikingly similar views during the same period—from 1920s to 1930s—albeit without any knowledge of Neurath’s thought in particular, or for that matter the Vienna Circle in general. The chapter reveals similarities as well as differences between Neurath and Teige on Marxism, science and architecture, and the Bauhaus, as well as a discussion of the relations of both to the contemporaries, most importantly Adolf Loos, Josef Frank and Hannes Meyer.

Working from Within: The Nature and Development of Quine's Naturalism. By Verhaegh Sander.

The age-old question “What is truth?” is not an unambiguous one. There are at least two different meanings. In one sense, it is a semantic question about the meaning of the word “truth” and/or a metaphysical question about the nature of the property of truth, that is, how truth can be defined in terms of other notions, if it is definable at all. In another sense, it is an epistemological question about the criterion or test of truth, that is, how (...) we can recognize or accept (empirical) propositions as true. Ayer, in Language, Truth and Logic (LTL) and some other articles, tried to convince us that when we attempt to elucidate a theory of truth, we are only engaging in the epistemological project of finding the criterion of truth. This anti-semantical and anti-metaphysical view is based on Ayer’s (radical) deflationism about truth. In this chapter, I will argue that since Ayer did not accept that the criterion of truth is intimately related to the concept of truth, he can be seen as a deflationist about the nature of truth and as an advocate of a certain (Schlickian) kind of correspondence conception about the criterion of truth. His position would not be tenable if he had maintained what some of his contemporaries accepted, namely that there is a close connection between the two truth-theoretical tasks: the definitional and the criterial one.
