Rudolf Carnap’s formative years as a philosopher were his time in Jena where he studied mathematics, physics, and philosophy, among others, with Gottlob Frege, the neo-Kantian Bruno Bauch, and Herman Nohl, a pupil of Wilhelm Dilthey.2 Whereas both the influence of Frege and of the neo-Kantians is quite well known,3 the importance of the Dilthey school for Carnap’s intellectual development was recently highlighted by scholars, such as Gottfried Gabriel and Hans-Joachim Dahms.4 Although Carnap himself was interested mainly in the problems (...) of logic and the philosophy of the natural sciences, the community in which he worked until he went to Vienna in 1926 was neither a community of neo-Kantian philosophers nor of logicians or philosophers of the natural sciences but a community of members of the Dilthey school that were interested in history of philosophy,5 pedagogic,6 aesthetics,7 and sociology.8 Carnap and his friends were all members of the so-called Seracircle, a group of young people that met frequently in Jena and, between 1919 and 1926, also in Carnap’s home in Buchenbach near Freiburg.9 The first version of the Aufbau was written in close connection with this group of young people that were interested in a reform of the whole society, including arts, politics, sciences, and everyday life. In Carnap’s Werkstatt in Buchenbach, the Aufbau and at least two more manifestos of a more or less philosophical nature were written: Franz Roh’s “Nach-Expressionismus” and Wilhelm Flitner’s “Laienbildung.”10 Given these historical facts, we must conclude that the Aufbau is the product of an intellectual enterprise that developed in close connection with the Dilthey school, but in which Frege and the neo-Kantians seem to have played only a small role.

. Based on a reconstruction of the development of Rudolf Carnap’s views from the Aufbau until the 1960s, this paper provides an account of the philosopher’s understanding of non-cognitivism, which is here seen as in line with the so-called scientific world-conception of left-wing logical empiricism. The starting point of Carnap’s conception is the claim that every human decision depends on certain attitudes that cannot be justified at a cognitive level, that are neither based on empirical facts nor logical reasoning. The (...) key features of Carnap’s non-cognitivism, however, go beyond this general basis and involve several fundamentally moral commitments, such as a commitment toward science, and the embracing of moral attitudes as the result of a long-term process of rational discourse. I argue that these commitments contained in Carnap’s non-cognitivism/scientific world-conception establish a genuinely political worldview that is characteristic of left-wing logical empiricism and converges with socialism and democracy.

Der Band versammelt einen Großteil der Beiträge, die internationale Experten anlässlich der Tagung „Philosophie und Wissenschaft bei Hermann Cohen“ im November 2014 am Institut Wiener Kreis der Universität Wien präsentiert haben. Mit der Tagung zu Hermann Cohen, der zusammen mit Paul Natorp die Marburger Schule begründete, wurden zwei Ziele verfolgt: erstens die Aspekte in der Philosophie des Kantianers Cohen herauszuarbeiten, die an die Idee einer Einheitswissenschaft anknüpfen und zweitens Divergenzen und Übereinstimmungen Cohens mit der wissenschaftlichen Weltauffassung, der Programmatik des Wiener (...) Kreises um Rudolf Carnap und Moritz Schlick zu identifizieren. Der Tagungsband ist in drei Teile gegliedert. Die Aufsätze im ersten Teil beschäftigen sich mit der Bedeutung von Erfahrung und Empirismus für das Philosophieverständnis Hermann Cohens. Im zweiten Teil gehen die Autoren der Frage nach, welche Rolle Theorien aus den Bereichen Mathematik, Naturwissenscha ften und Psychologie für Cohens Denken gespielt haben – unter anderem Hermann von Helmholtz‘ Theorie des Messens und die Bedeutung der Infinitesimalrechnung für die Philosophie der Marburger Schule. Die Beiträge im dritten Teil des Bandes stellen die Philosophie Cohens und der Marburger Schule den Vertretern des Wiener Kreises und der Berliner Gruppe um Hans Reichenbach gegenüber. Dabei wird Reichenbachs Rezeption der Relativitätstheorie in den Kontext einer Relativierung Kants bei Cohen und Ernst Cassirer gestellt und „versteckte Verwandtschaften“ zwischen Cohen und dem Logischen Empirismus aufgedeckt. Der Band richtet sich an Wissenschaftler auf dem Gebiet der Geschichte der Philosophie. (shrink)

This article is concerned with the development of philosophy of science in the 1970s. The explanatory framework is the picture of two fundamental split-offs: the controversial establishment of history and sociology of science and of formal philosophy of science as independent disciplines, against the background of more traditional “conceptual” varieties of philosophy of science. I illustrate these developments, which finally led to somewhat “purified” versions of the respective accounts, by examining a case study, namely, that of the structuralist school, which (...) emerged in the 1970s as an attempt to reconcile historical and formal approaches in philosophy of science. I try to explain the failure of this initial program of “Kuhn Sneedified” and its transition to a more purified formalist version, on the basis of the fact that the former attempt was caught somewhere amid the purism of conceptual, historical, and formal accounts of philosophy of science.

Der logische Aufbau der Welt wurde 1928 publiziert, zwei Jahre nachdem Carnap sich in Wien mit dem Manuskript des Buches habilitiert hatte. Entstanden ist Carnaps Buch jedoch in einer Zeit, in der dieser noch nicht in Wien tätig war. Die Niederschrift erfolgte im Jahr 1925 in Buchenbach bei Freiburg; die Vorgeschichte reicht zurück bis ins Jahr 1920. Wie viel Wien oder Wiener Kreis steckt also eigentlich im Aufbau? Wie sehr spiegelt der Aufbau umgekehrt die philosophische Situation in Carnaps frühem Umfeld (...) in Jena und Freiburg wieder? Ist der Aufbau ein Stück österreichische oder ein Stück deutsche Philosophie oder beides? Um diese Fragen auf einer soliden empirischen Grundlage beantworten zu können, wird hier das vorhandene Material ausgewertet, das die Entstehung von Carnaps Buch dokumentiert. Dabei handelt es sich, neben den publizierten Texten Carnaps aus dieser Zeit, um folgende Quellen: Carnaps Tagebücher und Leselisten, verschiedene Briefwechsel, Manuskripte und Fragmente aus den Nachlässen von Carnap, Hans Reichenbach, Moritz Schlick, Franz Roh und anderen.

In this paper, I re-examine Barry Smith’s list of features of Austrian Philosophy in his Austrian philosophy. The legacy of Franz Brentano. Open Court, Chicago, 1994). I claim that the list properly applies only in a somewhat abbreviated form to all significant representatives of Austrian Philosophy. Moreover, Smith’s crucial thesis that the features of Austrian Philosophy are not shared by any German philosopher only holds if we compare Austrian Philosophy to a canonical list of German Philosophy II. This list, however, (...) was established in twentieth century as a result of historical misrepresentations. If we correct these misrepresentations, we obtain another list of hidden representatives called German Philosophy I. German Philosophy I is fundamentally identical to Austrian Philosophy, whereas German Philosophy II is entirely different from both Austrian Philosophy and German Philosophy I. Therefore, a slightly modified version of Smith’s Austrian Philosophy account still makes sense as a tool to position the proscientific and rational currents of Austrian Philosophy and German Philosophy I against the tendentially anti-scientific and irrational current of German Philosophy II.

This article reevaluates Hermann Ebbinghaus’s famous criticisms of Wilhelm Dilthey’s 1894 essay “Ideas for a Descriptive and Analytic Psychology,” to determine how Dilthey’s diverse approaches toward philosophy and the human sciences are related to experimental psychology and to hypothetico-deductive science. It turns out that Ebbinghaus falsely accuses Dilthey of rejecting experimental psychology overall, while, in fact, Dilthey rejects only a specific misuse of experimental psychology: as a way to provide a foundation for the humanities. At the same time, Dilthey recognizes (...) several ways in which philosophy and the human sciences might benefit from experimental psychology. Although it clearly rules out experimental psychology, Dilthey’s descriptive psychology involves a hypothetico-deductive standpoint that intermediates, with some success, between modern social science and nineteenth-century hermeneutics.

This paper develops the first parts of a logical framework for the empirical sciences, by means of a redefinition of theory structuralism as originally developed by Joseph Sneed, Wolfgang Stegmüller, and others, in the context of a ‘rigid’ logic as based on a fixed (therefore rigid) ontology. The paper defends a formal conception of the empirical sciences that has an irreducible ontological basis and is unable, in general, to provide purely structural characterizations of the domain of a theory. The extreme (...) rationalist utopia of a characterization of the real world ‘up to isomorphism’, therefore, is rejected. (shrink)

Die hier zusammengefassten statistischen Daten waren ursprünglich als Teil meiner Habilitationsschrift "〈Deutscher Empirismus〉. Studien zur Philosophie im deutschsprachigen Raum 1830-1930" (erscheint 2016 oder 2017 bei Springer) gedacht. In der Endfassung des Manuskripts wurden diese Daten jedoch nicht mehr im Detail aufgenommen, weil sich herausgestellt hat, dass eine plausible Interpretation dieses Materials den Rahmen meiner Arbeit bei weitem sprengen und umfangreiche zusätzliche Recherchen erfordern würde. Dieses Dokument versteht sich als Skizze zu einer in Zukunft noch zu schreibenden Arbeit zur Universitätsstatistik und (...) als Ergänzung zu dem oben genannten Buch. (shrink)

In the last two sections of Structure, Thomas Kuhn first develops his famous threefold conception of the incommensurability of scientific paradigms and, subsequently, a conception of scientific progress as growth of empirical strength. The latter conception seems to be at odds with the former in that semantic incommensurability appears to imply the existence of situations where scientific progress in Kuhns sense can no longer exist. In contrast to this seeming inconsistency of Kuhns conception, we will try to show in this (...) study that the semantic incommensurability of scientific terms appears to be fully compatible with scientific progress. Our argumentation is based on an improved version of the formalization of Kuhns conception as developed in the 1970s by Joseph Sneed and Wolfgang Stegmüller: In order to be comparable, incommensurable theories need the specification of relations that refer to the concrete ontologies of these theories and involve certain truth claims. The original structuralist account of reduction fails to provide such relations, because (1) it is too structural and (2) it is too wide. Moreover, the original structuralist account also fails to cover important cases of incommensurable theories in being too restrictive for them. In this paper, we develop an improved notion of “reduction” that allows us to avoid these shortcomings by means of a more flexible device for the formalization of (partially reductive) relations between theories. For that purpose, we use a framework of rigid logic, i.e., logic that is based on a fixed collection of objects. (shrink)

Wilhelm Dilthey's epistemology is an attempt at a more cogent and non-reductionist version of empiricism. According to Dilthey the concepts and ideas of the human mind are empirical objects in their own right. Thus, philosophy as the study of these “facts of consciousness” turns out to be an empirical science; its methods are the methods of psychology, sociology, and history. These views of Dilthey are firstly described in the context of their competitive philosophical programs—“metaphysics”, empiricism and -Kantianism—, then they are (...) compared with recent developments of empirical philosophy, namely van Fraassens neo-empiricism, experimental philosophy, and the sociology of philosophical knowledge.

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)

This book studies how the relationship between philosophy, morality, politics, and science was conceived in the Vienna Circle and how this group of philosophers tried to position science as an antidote to totalitarianism and irrationalism. This leads to investigation of the still understudied views of the Vienna Circle on moral philosophy, meta-ethics, and the relationship between philosophy of science and politics. Including papers from an international group of scholars, The Socio-ethical Dimension of Knowledge: The Mission of Logical Empiricism addresses these (...) topics and makes them available to scholars in the field of history of philosophy of science.

Rudolf Carnap (1891-1970) and Otto Neurath (1882-1945) decisively determined the development of the scientific world view of logical empiricism. The contributions to this volume illuminate from different perspectives the intricate relations between these two key thinkers.

Im Zentrum dieses Bandes stehen die Beiträge einer Tagung, die im Oktober 2017 an der Universität Konstanz stattgefunden hat. Thema der Tagung war ein den historischen Kontext einbeziehender Blick auf den frühen Rudolf Carnap, vom Ende des Ersten Weltkriegs bis zur Emigration Ende 1935. Der 1891 in Ronsdorf bei Wuppertal geborene Rudolf Carnap entschloss sich erst relativ spät zu einer Karriere als akademischer Philosoph, nämlich 1920, nachdem er sein durch den Krieg unterbrochenes Studium der Physik und Philosophie in Jena und (...) Freiburg abgeschlossen und kurze Zeit überlegt hatte, als Lehrer in der Schulreform-Bewegung zu arbeiten. Es folgte die philosophische Promotion im Jahr 1921, bei Bruno Bauch in Jena, mit einer Doktorarbeit zum Raumproblem. 1923 organisierte Carnap, gemeinsam mit Hans Reichenbach und anderen, eine für die Entstehung des Logischen Empirismus bedeutsame kleine Tagung in Erlangen. Auf Einladung von Moritz Schlick habilitierte er sich 1926 an der Universität Wien und verbrachte die Zeit bis 1931 zumindest teilweise in Wien, als eines der Kernmitglieder des Wiener Kreises um Moritz Schlick. Seine Habilitationsschrift erschien 1928 unter dem Titel Der logische Aufbau der Welt (hier immer Aufbau). 1931 folgte Carnap einem Ruf an die Deutsche Universität Prag. In den darauffolgenden Jahren blieb aber der enge Kontakt mit Wien und dem Wiener Kreis erhalten. Carnaps hauptsächliche Arbeit in dieser Zeit war seinem zweiten großen Buchprojekt gewidmet, der 1934 publizierten Logischen Syntax der Sprache. Daneben verfasste Carnap in seiner Zeit in Wien und Prag auch zahlreiche Aufsätze, zu unterschiedlichen Aspekten der Logik, der Metaphysikkritik und der Wissenschaftstheorie. Er war Mitautor des Manifests Wissenschaftliche Weltauffassung: Der Wiener Kreis und nahm regen Anteil an den zahlreichen wissenschaftlichen Aktivitäten des Logischen Empirismus, von der Gründung der Zeitschrift Erkenntnis bis hin zum Projekt einer Enzyklopädie der Einheitswissenschaft. Spätestens ab 1933 musste Carnap jedoch feststellen, dass an eine weitere wissenschaftliche Karriere in dem von Faschismus und Nationalsozialismus geprägten politischen Klima in Kontinentaleuropa nicht zu denken war. Er strebte deshalb die Emigration ins englischsprachige Ausland an, die schließlich Ende 1935 gelang, als Carnap ein Angebot von der Universität Chicago erhielt. Obwohl Carnap nur den kleineren Teil der in diesem Band abgedeckten eineinhalb Jahrzehnte in Wien verbracht hat, widmet sich der Großteil der hier versammelten Beiträge schwerpunktmäßig der für Carnaps philosophische Karriere zentralen Wiener Zeit.

In 1917/18 the German publisher Eugen Diederichs organized three “closed meetings” at Lauenstein castle in Upper Franconia (Germany) where about 60 representatives of science, art, and “the youth” discussed “the meaning and purpose of our time.” (273) The present volume delivers the definitive documentation of these historically important meetings. At the same time, it brings together three different sources, carefully selected, edited, and introduced by Meike Werner.
