The final work of the esteemed philosopher William Demopoulos supplants logical empiricism's accounts of physical theories, which fail to satisfactorily engage modern physics. Arguing for a new appreciation of the tightly woven character of theory and evidence, Demopoulos offers novel insights into the distinctive nature of quantum reality.

Philosophy of biology is often said to have emerged in the last third of the twentieth century. Prior to this time, it has been alleged that the only authors who engaged philosophically with the life sciences were either logical empiricists who sought to impose the explanatory ideals of the physical sciences onto biology, or vitalists who invoked mystical agencies in an attempt to ward off the threat of physicochemical reduction. These schools paid little attention to actual biological science, and (...) as a result philosophy of biology languished in a state of futility for much of the twentieth century. The situation, we are told, only began to change in the late 1960s and early 1970s, when a new generation of researchers began to focus on problems internal to biology, leading to the consolidation of the discipline. In this paper we challenge this widely accepted narrative of the history of philosophy of biology. We do so by arguing that the most important tradition within early twentieth-century philosophy of biology was neither logical empiricism nor vitalism, but the organicist movement that flourished between the First and Second World Wars. We show that the organicist corpus is thematically and methodologically continuous with the contemporary literature in order to discredit the view that early work in the philosophy of biology was unproductive, and we emphasize the desirability of integrating the historical and contemporary conversations into a single, unified discourse.

This text provides an extensive exploration of the relationship between the thought of Otto Neurath and Rudolf Carnap, providing a new argument for the complementarity of their mature philosophies as part of a collaborative metatheory of science. In arguing that both Neurath and Carnap must be interpreted as proponents of epistemological naturalism, and that their naturalisms rest on shared philosophical ground, it is also demonstrated that the boundaries and possibilities for epistemological naturalism are not as restrictive as Quinean orthodoxy has (...) previously suggested. Both building on and challenging the scholarship of the past four decades, this naturalist reading of Carnap also provides a new interpretation of Carnap’s conception of analyticity, allowing for a refutation of the Quinean argument for the incompatibility of naturalism and the analytic/synthetic distinction. In doing so, the relevance and potential importance of their scientific meta-theory for contemporary questions in the philosophy of science is demonstrated. This text appeals to students and researchers working on Logical Empiricism, Quine, the history of analytic philosophy and the history of philosophy of science, as well as proponents of naturalized epistemology.

The logical empiricists expressed a consistent attitude to racial categorisation in both the ethical and scientific spheres. Their attitude may be captured in the following slogan: human racial taxonomy is an empirically meaningful mode of classifying persons that we should refrain from deploying. I offer an interpretation of their position that would render coherent their remarks on race with positions they adopted on the scientific status of taxonomy in general, together with their potential moral or political motivations for adopting (...) that position.

This paper considers George A. Reisch’s account of the role of Cold War political forces in shaping the apolitical stance that came to dominate philosophy of science in the late 1940s and 1950s. It argues that at least as early as the 1930s, Logical Empiricists such as Rudolf Carnap already held that philosophy of science could not properly have political aims, and further suggests that political forces alone cannot explain this view’s rise to dominance during the Cold War, since (...) political forces cannot explain why a philosophy of science with liberal democratic, anti-communist aims did not flourish. The paper then argues that if professionalization is understood in the right way, it might point toward an explanation of the apolitical stance of Cold War philosophy of science. (shrink)

Is logical empiricism incompatible with a critical social science? The longstanding assumption that it is incompatible has been prominent in recent debates about welfare economics. Sen’s development of a critical and descriptively rich welfare eco nomics is taken by writers such as Putnam, Walsh and Sen to involve the excising of the influence of logical empiricism on neo-classical economics. However, this view stands in contrast to the descriptively rich contributions to political economy of members of the left Vienna (...) Circle, such as Otto Neurath. This paper considers the compatibility of the meta-theoretical commitments of Neurath and others in the logical empiricist tradition with this first-order critical political economy. (shrink)

This collection of essays reexamines the origins of logical empiricism and offers fresh insights into its relationship to contemporary philosophy of science.

This book explores the complexity of two philosophical traditions, extending from their origins to the current developments in neopragmatism. Chapters deal with the first encounters of these traditions and beyond, looking at metaphysics and the Vienna circle as well as semantics and the principle of tolerance. There is a general consensus that North-American pragmatism and European Logical Empiricism were converging philosophical traditions, especially after the forced migration of the European Philosophers. But readers will discover a pluralist image of this (...) relation and interaction with an obvious family resemblance. This work clarifies and specifies the common features and differences of these currents since the beginning of their mutual scientific communication in the 19th century. The book draws on collaboration between authors and philosophers from Vienna, Tübingen, and Helsinki, and their networks. It will appeal to philosophers, scholars in the history of philosophy, philosophers of science, pragmatists and beyond. (shrink)

Logical Empiricism is commonly regarded as uninterested in, if not hostile to sociological investigations of science. This paper reconstructs the views of Otto Neurath and Philipp Frank on the legitimacy and relevance of sociological investigations of theory choice. It is argued that while there obtains a surprising degree of convergence between their programmatic pronouncements and the Strong Programme, the two types of project nevertheless remain distinct. The key to this differences lies in the different assessment of a supposed dilemma (...) facing post-Mertonian sociologists of science. (shrink)

I criticize conceptual pluralism, as endorsed recently by John Dupre and Philip Kitcher, for failing to supply strategies for demarcating science from non-science. Using creation-science as a test case, I argue that pluralism blocks arguments that keep creation-science in check and that metaphysical pluralism offers it positive, metaphysical support. Logical empiricism, however, still provides useful resources to reconfigure and manage the problem of creation-science in those practical and political contexts where pluralism will fail.

Much feminist philosophy of science has been developed as a reaction against logical empiricism and the associated view that social factors play no role in good science. Recent accounts of the Vienna Circle that highlighted the ways in which some of its members attempted to combine their empiricism with emancipatory politics are used here as a basis on which to reassess the relationship between logical empiricism and feminism. The focus is chiefly on Otto Neurath.

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.

In the light of two unpublished letters from Carnap to Kuhn, this essay examines the relationship between Kuhn's The Structure of Scientific Revolutions and Carnap's philosophical views. Contrary to the common wisdom that Kuhn's book refuted logical empiricism, it argues that Carnap's views of revolutionary scientific change are rather similar to those detailed by Kuhn. This serves both to explain Carnap's appreciation of The Structure of Scientific Revolutions and to suggest that logical empiricism, insofar as that program rested (...) on Carnap's shoulders, was not substantially upstaged by Kuhn's book.

Scientific realism is the view that the theoretical entities of science exist. Atoms, forces, electromagnetic fields, and so on, are not merely instruments for organizing observational data but are real and causally effective. This view seems to be hardly compatible with the logical empiricist agenda: As common wisdom has it, logical empiricism is mainly characterized by a strong verification criterion of meaning, i.e., by the project of defining the meaning of theoretical terms by virtue of the meaning (...) of purely observational terms. However, it has been largely ignored by the historians of logical empiricism that there indeed existed a realist faction within the logical empiricist movement. (shrink)

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. (...) class='Hi'>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.

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 paper argues against a commitment to metaphysical necessity, semantic modalities are enough. The best approaches to elucidate the semantic modalities are (still) versions of lingustic ersatzism and fictionalism, even if only developed in parts. Within these necessary properties and the difference between natural and semantic laws can be accounted for. The proper background theory for this is an updated version of Logical Empiricism, which is congenial to recent trends in Structural Realism. The anti-metaphysical attitude of Logical Empiricism (...) deserves revitalization. Another target besides metaphysical necessity are substantial forms of iterated modalities, as used, for instance, in the philosophy of religion. (shrink)

The mainstream of the philosophy of science in the second quarter of this century—the so-called “logical empiricist” or “logical positivist” movement—assumed that theoretical language in science is parasitic upon observation language and can be eliminated from scientific discourse by disinterpretation and formalization, or by explicit definition in or reduction to observational language. But several fashionable views now place the onus on believers in an observation language to show how such a language is meaningful in the absence of (...) a theory.In the present paper, I propose to show why logical positivism failed to do justice to the basic empirical and logical problems of philosophy of science. I also wish to consider why the drastic reaction, typified by Thomas Kuhn and Paul Feyerabend, fails t o provide a suitable alternative, and to suggest that the radical approaches of recent writers such as Mary Hesse and Dudley Shapere hold out a genuine promise of dealing effectively with the central tasks that face the philosopher of science today.

In this article, I seek to shed new light on a lesser-known stage of the development of Hans Reichenbach’s thought, namely his research, output and teaching activities at Istanbul University. I argue that the experience of Turkish exile was decisive in the elaboration of Reichenbach’s probability theory of meaning and knowledge. His work Experience and Prediction, produced while in Istanbul, should therefore be put in its Turkish context of elaboration and reception. To this end, I will take into consideration not (...) only Reichenbach’s efforts to popularize and extend the Berlin Group’s program of scientific philosophy in Turkey and throughout Europe in the 1930s, but also the forgotten work of Reichenbach’s students—most of them women—at Istanbul University.

The fundamental tenet of logical empiricism is that the warrant for all scientific knowledge rests upon empirical evidence in conjunction with logic, where logic is taken to include induction or confirmation, as well as mathematics and formal logic (see evidence and confirmation). This appears to conflict strongly with Thomas Kuhn's famous statement that scientific theory choice depends on considerations that go beyond observation and logic, even when logic is construed so as to include confirmation (see kuhn and pragmatic factors (...) in theory acceptance). Logical empiricists deny the possibility of synthetic a priori knowledge ‐ that is, substantive knowledge of the world based on pure reason. Those who, with W. V. Quine, reject the analytic/synthetic distinction, would, I suppose, question the possibility of a priori knowledge altogether (see quine). Contemporary logical empiricists disagree, however, about such basic issues as the nature of empirical evidence, the status and structure of confirmation or inductive inference, the nature of scientific explanation, and the character of scientific theories, to name but a few examples (see theories; explanation; confirmation, paradoxes of).

If there is a movement or school that epitomizes analytic philosophy in the middle of the twentieth century, it is logical empiricism. Logical empiricists created a scientifically and technically informed philosophy of science, established mathematical logic as a topic in and tool for philosophy, and initiated the project of formal semantics. Accounts of analytic philosophy written in the middle of the twentieth century gave logical empiricism a central place in the project. The second wave of interpretative accounts (...) was constructed to show how philosophy should progress, or had progressed, beyond logical empiricism. The essays survey the formative stages of logical empiricism in central Europe and its acculturation in North America, discussing its main topics, and achievements and failures, in different areas of philosophy of science, and assessing its influence on philosophy, past, present, and future.

I have taken part in a wealth of good seminars before and after 1936, but my experience as a participant of that seminar makes it, (...) for me, stand out as unsurpassed. (shrink)

Value judgments are meaningless. This thesis was one of the notorious tenets of Carnap's mature logical empiricism. Less well known is the fact that in the Aufbau values were considered as philosophically respectable entities that could be constituted from value experiences. About 1930, however, values and value judgments were banished to the realm of meaningless metaphysics, and Carnap came to endorse a strict emotivism. The aim of this paper is to shed light on the question why Carnap abandoned his (...) originally positive attitude concerning values. It is argued that his non-cognitivist attitude was the symptom of a deep-rooted and never properly dissolved tension between conflicting inclinations towards Neokantianism and Lebensphilosophie. In America Carnap's non-cognitivism became a major obstacle for a closer collaboration between logical empiricists and American pragmatists. Carnap's persisting adherence to the dualism of practical life and theoretical science was the ultimate reason why he could not accept Morris's and Kaplan's pragmatist theses that cognitivism might well be compatible with a logical and empiricist scientific philosophy.

In the first half of the 20th century, scientific models were hardly mentioned in philosophy of science. Models were not thought to be central elements of science, in contrast to theories. This attitude can be better understood when considering philosophical trends - Operationalism and Logical Empiricism - and scientific developments - the advent of quantum theory and relativity theory. This paper traces the philosophical currents and positions that prevented models from being recognized as playing an important role in science. (...) It goes on to examine why the hostile attitude towards models slowly tempered in the 1950s. The contributions of Mary Hesse and Ernest Hutten are shown to foreshadow recent debates that have arisen in the context of the philosophical study of scientific models. /// Segundo a autora, na primeira metade do século XX, os modelos científicos praticamente não eram mencionados em Filosofia da Ciência. Os modelos não eram considerados como elementos centrais da Ciência, ao contrário das teorias. Para a autora, uma tal atitude pode ser melhor compreendida se se atender ao influxo de importantes movimentos filosóficos, como sejam o Operacionalismo e o Empirismo Lógico, bem como ao impacto de alguns desenvolvimentos científicos, como sejam o aparecimento da teoria quântica e da teoria da relatividade. Nesse sentido, o presente artigo visa estabelecer as correntes filosóficas e as posições científicas que contribuíram para que os modelos não fossem reconhecidos no importante papel que desempenham no desenvolvimento da Ciência. De um modo especial, a autora examina com particular cuidado o lento processo de redução da hostilidade em relação aos modelos durante a década de 50 do século xx. Assim, o artigo mostra de um modo especial até que ponto os contributos de Mary Hesse e de Ernest Hutten foram antecipadores de alguns dos debates mais recentes que se sucederam no contexto do estudo filosófico dos modelos científicos.

A division has arisen within the naturalist school of moral philosophy, with the contenders being "the emotive theorists vs. the cognitive theorists." the author suggests that the fundamental agreements between the groups far outweigh the peripheral and sometimes illusory disagreements. the article establishes the areas of agreement, deals with illusory disagreements, and indicates the peripheral disagreements can be considered disagreements in emphasis.

Logical empiricism is commonly seen as a counter-position to scientific realism. In the present paper it is shown that there indeed existed a realist faction within the logical empiricist movement. In particular, I shall point out that at least four types of realistic arguments can be distinguished within this faction: Reichenbach’s ‘probabilistic argument,’ Feigl’s ‘pragmatic argument,’ Hempel’s ‘indispensability argument,’ and Kaila’s ‘invariantist argument.’ All these variations of arguments are intended to prevent the logical empiricist agenda (...) from the shortcomings of radical positivism, instrumentalism, and other forms of scientific antirealism. On the whole, it will be seen that logical empiricism and scientific realism are essentially compatible with each other. Especially Kaila’s invariantist approach to science (and nature) comes quite close to what nowadays is discussed under the label ‘structural realism.’ This, in turn, necessitates a fundamental reevaluation of Kaila’s role in the logical empiricist movement in particular and in twentieth-century philosophy of science in general.

This chapter contains sections titled: Logical Positivism: Basic Information The Hempelian Model of Explanation in Historiography Popperian Critique of Historicism Conclusion Bibliography.

Logical Positivists had a very lively interest in the revolutionary science of their time, but also in modern art and especially in ‘international style’ architecture. Surprisingly they never published a representative volume or longer statement on art and architecture. But: it is not well known that Otto Neurath, their leading organizer and spokesman, invited the eminent art historian and critic Meyer Schapiro to contribute a volume on art to the International Encyclopedia of Unified Science. Schapiro failed to deliver the (...) promised book. But from the extended correspondence and some material in the Schapiro papers one can describe the general direction the thing would have taken. The correspondence is also very interesting, because it also covers questions of the endangered peace and the approaching war, the academic scene in Europe and in the USA, and surprisingly: Martin Heidegger. Neurath died in 1945, but Schapiro came back to the Heidegger theme in 1968 when he wrote his famous harsh criticism of Heidegger’s programmatic long paper “Das Kunstwerk” where he interprets one of Van Gogh’s shoe-paintings. Schapiro’s short article caused much controversy then. (shrink)

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.

I give a revision (“reload”) of an earlier paper on logico-empiricism’s philosophy of biology by checking its central theses against the background of the international conferences of Prague (1934), Paris (1935), and Copenhagen (1936), so important for the development of logical empiricism and its spread in the western world. My theses are that logical empiricism did not contribute in the same way to the development of philosophy of biology, as it did e.g. to the development of philosophy of (...) mathematics or physics. The reasons for this failure were: (1) logical empiricists were unexperienced in biological science. (2) They concentrated on an unproductive ('ideological') framework (anti-vitalism, reduction) that they took to be philosophy of biology. (3) This prevented them from dealing with actual problems of biological science. Between the various sections of the paper, I insert “intermezzos” that present several conference participants in a wider historical context (Great War, persecution, language). (shrink)
