Ernst Waldfried Josef Wenzel Mach was born 18 February 1838 in the Moravian village of Chrlice (near Brno), at that time part of the Austrian Monarchy, now the Czech Republic, and died 19 February 1916 in Vaterstetten (near Munich). He enjoyed a very successful career as an experimental physicist (the unit for the velocity of sound has been named after him). His importance for the philosophy of science derives mainly from his “historico‐critical” writings (Mach 1872, 1883, 1896b, 1921). Mach studied mathematics and physics at the University of Vienna (1855–60, doctorate in physics 1860, his “Habilitation” (i.e., qualification to become a university professor) 1861) and his subsequent work was in the physiology of the senses. In 1864 he became professor first of mathematics and then (1866) of physics at Graz University; from 1867 to 1895 he was professor of experimental physics at Prague University; and in 1895 he took a chair in “Philosophy, especially the History and Theory of the Inductive Sciences” at Vienna University. In 1898 a stroke ended Mach's university teaching, but he was able to continue scientific work to a certain degree.

This open access book examines the many contributions of Paul Lorenzen, an outstanding philosopher from the latter half of the 20th century. It features papers focused on integrating Lorenzen's original approach into the history of logic and mathematics. The papers also explore how practitioners can implement Lorenzen’s systematical ideas in today’s debates on proof-theoretic semantics, databank management, and stochastics. Coverage details key contributions of Lorenzen to constructive mathematics, Lorenzen’s work on lattice-groups and divisibility theory, and modern set theory and Lorenzen’s critique of actual infinity. The contributors also look at the main problem of Grundlagenforschung and Lorenzen’s consistency proof and Hilbert’s larger program. In addition, the papers offer a constructive examination of a Russell-style Ramified Type Theory and a way out of the circularity puzzle within the operative justification of logic and mathematics. Paul Lorenzen's name is associated with the Erlangen School of Methodical Constructivism, of which the approach in linguistic philosophy and philosophy of science determined philosophical discussions especially in Germany in the 1960s and 1970s. This volume features 10 papers from a meeting that took place at the University of Konstanz.

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.

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).

Grünbaum's three chief fields of research were space-time philosophy, the methodological credentials of psychoanalysis, and reasons given in favor of the existence of God. Grünbaum defended the so-called conventionality thesis of physical geometry. He partially followed Hans Reichenbach in this respect but developed a new ontological argument for the conventionality claim in addition. In addressing the physical basis of the direction of time, Grünbaum advocated that there is a physical basis for the distinction between the past and the future, but no such basis for the idea of a ‘present’ moving through time. His main claim in scrutinizing Freud’s theory methodologically was that supporting the causal claims Freud made would have required data that go beyond the clinical setting. Finally, Grünbaum worked on the philosophy of religion and set out to undermine arguments for the existence of God.

Michael Ende’s bestseller/The Neverending Story/is set in a magical world called “Fantastica”. In Fantastica, there are heroes and villains, just as in the world of universities and academies. There is even an entity, or better: a non-entity of shaky existence, das Nichts, the Nothingness – loved by some philosophers like Martin Heidegger. In Fantastica Nothingness is able to create trouble and destruction. The same is true in the land of academic history and philosophy of science – let us call it “HOPOSia”. In HOPOSia, particularly in its Anglophone provinces, Nothingness of knowledge and information has succeeded in building up strong opinions about the topic “Mach and Relativity”, and has created confusion and disinformation. However, you may slightly relax; our story in HOPOSia is less cruel so far and more peaceful than what happens in Fantastica. Sometimes it has even entertaining aspects. There are similarities, though: If there had not been lies and manipulation of believes, our story would have ended years ago. It went on instead and will possibly do so forever.

Ce chapitre reprend, en l’enrichissant, un article antérieur sur la philosophie de la biologie de l’empirisme logique, en en examinant les thèses centrales telles qu’elles sont exprimées lors des rencontres de Prague, de Paris et de Copenhague, rencontres décisives pour le développement du mouvement et son rayonnement dans le monde occidental. Je montre que l’empirisme logique n’a pas contribué au développement de la philosophie de la biologie, comme il l’a fait pour celui de la philosophie de la physique ou des mathématiques. Les raisons de cet échec sont triples: 1o) les empiristes logiques n’avaient qu’une vague connaissance des sciences biologiques; 2o) ils se sont focalisés sur un cadre stérile, l’antivitalisme et le réductionisme, qu’ils prenaient pour la philosophie de la biologie; 3o) cela les a empêchés de traiter des véritables problèmes de la biologie. Entre les différentes sections de ce chapitre, j’insère des « intermezzos» qui replacent différents protagonistes de ces rencontres dans un contexte plus large.

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.

n this article the author develops a critique of reductionism in biological sciences from three different points of view. The first is related to the problem of reduction in the context of scientific theories. More specifically, reduction deals with a special form of intertheoretic relationship between molecular biology and the rest of biology. The second meaning of reductionism has to do with the significance of its genetic outfit for the ontogeny of an organism, i.e. its development from zygote to its final or adult structure and function. Third, closely related to this more biological topic are questions about the anthropological consequences of the application of reductionistic methodologies for the explanation and evaluation of human behaviour.

Jonas' philosophical biology is an attempt to overcome the dualism, i.e., the alienation between man and world, which characterizes both Gnostic thinking and the Heiddegerian exis­tentialist approach that Jonas had applied in its interpretation. This dualism leads both approaches to despise or, at least, to neglect nature.Jonas' philosophical biology is intended to provide an insight into the phe­nomenon of life that is more than a mere reflection of scientific episte­mology. Rather, it regards itself as a cognitively significant approach towards the living in its own right. At the same time, philosophical biology is not intended as an alternative to the scientific enterprise, but instead as a desirable and even necessary complement of it. In develop­ing philosophical biology, Jonas additionally aims at securing a place for man in the order of the living that is more than just locating him somewhere in the order of primates.

The act of interpretation occurs in nearly every area of the arts and sciences. That ubiquity serves as the inspiration for the fourteen essays of this volume, covering many of the domains in which interpretive practices are found. Individual topics include: the general nature of interpretation and its forms; comparing and contrasting interpretation and hermeneutics; culture as interpretation seen through Hegel’s aesthetics; interpreting philosophical texts; methodologies for interpreting human action; interpretation in medical practice focusing on manifestations as indicators of disease; the brain and its interpretative, structured, learning and storage processes; interpreting hybrid wines and cognitive preconceptions of novel objects; and the importance of sensory perception as means of interpreting in the case of dry German Rieslings. In an interesting turn, Nicholas Rescher writes on the interpretation of philosophical texts. Then Catherine Wilson and Andreas Blank explicate and critique Rescher’s theories through analysis of the mill passage from Leibniz’s _Monadology._

Somewhat traumatized by the Galileo Affair the Church until recently showed low profile in the conflicts with science, evolutionary theory included. The talk presents a categorization of possible relationships between science and religion by distinguishing between "Galilean conflicts", which are about mutually exclusive statements about matters of fact, and Freudian conflicts where an empirical science tries to explain away religion as a phenomenon in its own right. In the light of this distinction I deal with the reactions of the Church since 1859, particularly with the ambiguous position of the present Pope.

In theoretical matters, ecclesiastical claims to knowledge have lead to various conflicts with science. Claims in orientational matters, sometimes connected to attempts to establish them as a rule for legislation, have often been in conflict with the justified claims of non-believers. In addition they violate the Principle of Autonomy of the individual, which is at the very heart of European identity so decisively shaped by the Enlightenment. The Principle of Autonomy implies that state legislation should not interfere in the life of individual citizens, as long as his or her actions do not violate the rights of others. This paper—using the example of the theory of evolution—rejects ecclesiastical claims to theoretical knowledge as completely unfounded and preposterous. In the case of orientational knowledge—using the example of euthanasia—ecclesiastical claims to (universalizable) knowledge are shown to be unfounded as well. The Church’s position with respect to euthanasia and a range of other bio-ethical topics, such as pre-marital sex, contraception, abortion, indissolubility of marriage, and homosexuality, rests on a very peculiar ethical position. This ethical position is the natural right theory, which—far from being universalizable—is shared by very few people. Among other things, this position presupposes the belief in God as the creator of nature, and the assumption that ethical norms can be derived from this premise. Thus ecclesiastical knowledge claims, cannot be justified in a way which could be reasonably supposed to be universally acceptable. Kant (see the quote) was the first to require this sort of justification. Claims that fail to implement Kant’s stipulations should be eliminated by what I would like to call “Kant’s razor”.

Das Thema dieser Überlegungen ist die deutsche Philosophie und sind deutsche Philoso­phen im Nationalsozialismus. (Für unsere politisch korrekten Ohrenspitzer(innen): es war keine Frau dabei.)1 Vorweg sei gesagt, verbrecherische Schurken finden wir unter ihnen nicht, anders als bei z. B. Juristen und Medizinern. ,,Auschwitz" wurde nicht von Philoso­phen betrieben. Die Praxisferne der Philosophie hat manchmal eben auch Vorteile. Teil I beschäftigt sich mit Philosophie und Philosophen im „Dritten Reich" im allgemei­nen. Teil II stellt eine Fallstudie (Oskar Becker) vor, während der dritte Teil ansatzweise eine noch skizzenhafte und vielleicht kontroverse Antwort auf die Frage versucht, welche philosophischen Umstände es begünstigt haben, daß Philosophen zu Naziphilosophen wurden, und welche dies vielleicht eher verhindert haben.
