This paper shows that Cassirer’s philosophy of mathematics underwent a significant transformation by the end of the 1920s. This transformation was due to Cassirer’s reception of the ‘foundational crisis’ within mathematics itself. David Hilbert’s conception of the ‘ideal elements’ of mathematics attracted Cassirer’s particular attention. Indeed, he sought a ‘transcendental deduction’ of these elements. Reflection on this issue is therefore essential to providing an adequate interpretation of the later Cassirer’s enterprise in the philosophy of mathematics.

American critical realism emerged in two forms: an ‘essentialist’ version defended, with some significant divergences, by George Santayana and C. A. Strong, and an ‘empirical’ version primarily defended by Roy Wood Sellars. Both forms of American critical realism aimed at an epistemologically convincing ‘representationalist’ account of perception. However, they were divided over issues of ontology. While Santayana and Strong invoked the notion of essence in order to ontologically reinforce their epistemological conceptions, Sellars attempted a more empirical, evolution-based approach. It will (...) be argued that Sellars’s view has more to recommend it because it better explains the actual mechanism of perceptual representation. (shrink)

The relationship between American pragmatism and American critical realism needs to be reconsidered. The two currents shared many aspects, but there were also significant differences. One of these differences pertains to the object of perception or, more precisely, to the question of what we talk about when we talk about this, for example, being blue. By re-addressing that question, some light can be shed on the historical development of analytic philosophy in the United States during the first half of the (...) twentieth century. My case in point is the respective positions of C. I. Lewis and R. W. Sellars. I shall point out that Sellars’s view has more to recommend it because it provides a more compelling framework for a comprehensive explanation of perception. (shrink)

Jeder Mensch steht in einem mehr oder weniger klaren Verhältnis zur eigenen Person, zu dem, was man auch das Selbst nennt. Hierbei spielt der Raum eine entscheidende Rolle - denn der Mensch ist nicht begreifbar ohne den Ort, an dem er sich aufhält. Matthias C. Müllers raumtheoretisch fundierte Neubeschreibung des philosophischen Großthemas Selbstheit bzw. Subjektivität zeigt nicht nur, daß menschliches Dasein nicht ohne Bezug auf das Wohnen im Raum begriffen werden kann, sondern auch, daß eigentlich nicht der Mensch den (...) Raum hervorbringt, sondern vielmehr der Raum den Menschen. (shrink)

American philosophical realism developed in two forms: “new” and “critical” realism. While the new realists sought to ‘emancipate’ ontology from epistemology and defended a direct theory of perception, the critical realists promoted a representationalist account of perception and thus argued for an epistemological dualism. Bertrand Russell’s early philosophical writings figured prominently in both of these American realist camps. However, while the new realists quite enthusiastically embraced the Russellian analytic style of reasoning (and Russell himself appreciated the American new realists as (...) anti-idealist allies), the critical realists were significantly more reserved toward Russell’s point of view. In the present paper, I identify the reasons for this difference in reception. In particular, I will show that the critical realists’ reservations pertained primarily to a more traditionalist—‘continental’—account of philosophy, whereas the neo-realists proved instrumental in setting the stage for later full-blown analytic philosophy in the United States.

"Die Grenzen des Revisionismus" befasst sich mit den erkenntnis- und wissenschafttheoretischen Positionen des frühen Moritz Schlick und des frühen Ernst Cassirer.

The late nineteenth- and early twentieth-century debate over ‘internal’ and ‘external’ relations is well explored, as far as its course in Britain is concerned. F. H. Bradley’s idealistic internalism, on the one hand, and Bertrand Russell’s realistic externalism, on the other, were at the center of this debate. Less well known, however, is that there was also a discussion about relations in the United States at the time. The central figures in this discussion were Edward Gleason Spaulding and John Dewey. (...) Like Russell, Spaulding advocated a realist-inspired externalism, while Dewey criticized this viewpoint from a pragmatist perspective. The aim of the present paper is to reconstruct the exchange between Spaulding and Dewey and to elaborate the specifics of this exchange. In doing so it will emerge, among other things, that, in contrast to Bradley’s idealist rejection of externalism, Dewey’s pragmatist attempt at a refutation was more in line with common sense and science and that Spaulding’s version of externalism differed markedly from Russell’s in its strong empirical orientation. Overall, an undeservedly forgotten chapter in the history of early twentieth-century American philosophy is revisited and reassessed. (shrink)

This volume is dedicated to the life and work of Ernest Nagel counted among the influential twentieth-century philosophers of science. Forgotten by the history of philosophy of science community in recent years, this volume introduces Nagel’s philosophy to a new generation of readers and highlights the merits and originality of his works. Best known in the history of philosophy as a major American representative of logical empiricism with some pragmatist and naturalist leanings, Nagel’s interests and activities went beyond these limits. (...) His career was marked with a strong and determined intention of harmonizing the European scientific worldview of logical empiricism and American naturalism/pragmatism. His most famous and systematic treatise on, The Structure of Science, appeared just one year before Thomas Kuhn’s even more renowned, The Structure of Scientific Revolutions. As a reflection of Nagel’s interdisciplinary work, the contributing authors’ articles are connected both historically and systematically. The volume will appeal to students mainly at the graduate level and academic scholars. Since the volume treats historical, philosophical, physical, social and general scientific questions, it will be of interest to historians and philosophers of science, epistemologists, social scientists, and anyone interested in the history of analytic philosophy and twentieth-century intellectual history.

In der Studie geht Matthias Neuber der Frage nach, in welchem Verhältnis das Konzept des Realismus und der logische Empirismus des Wiener Kreises, eine der dominanten Strömungen der deutschsprachigen theoretischen Philosophie des frühen 20. Jahrhunderts, zueinander stehen. Diese Fragestellung ist in der philosophiehistorischen Forschung bislang nur am Rande behandelt worden. Das ist umso erstaunlicher, als die neuere wissenschaftsphilosophische Realismusdebatte gerade durch den logischen Empirismus maßgeblich mitbestimmt worden ist. Der Autor geht aber noch einen Schritt weiter: Er begründet in (...) dem Band die These, dass es innerhalb des logischen Empirismus selbst Strömungen gab, die mit dem wissenschaftlichen Realismus kompatibel sind. Damit bezieht er eine Gegenposition zum Mainstream in der Deutung der wissenschaftsphilosophischen Realismusdebatte des 20. Jahrhunderts, denn der versteht den wissenschaftlichen Realismus als Gegenprogramm zum logischen Empirismus. Neuber liefert mit seiner philosophiehistorischen Studie nicht weniger als eine Neubewertung des Verhältnisses von Realismus und logischem Empirismus. Ein Werk, das sich insbesondere an Wissenschaftler, aber auch an fortgeschrittene Studierende auf dem Gebiet der Geschichte der Wissenschaftsphilosophie richtet. (shrink)

Alois Riehl was one of the few Kantian-inspired philosophers of the late nineteenth and early twentieth century who argued for a realist approach to Kant’s original doctrine. He therefore rejected prevailing idealist reconstructions and attempted to establish a view of Kant as an important forerunner of what he programmatically called ‘critical realism.’ In the present paper it will be shown what this exactly meant for the interpretation of Kant’s and especially Riehl’s own critique of idealism as a systematic position. In (...) particular, it is stated that anti-idealism in Riehlian terms amounts to a ‘realistic rehabilitation’ of Kantian things-in-themselves. Furthermore, some connections are drawn to early-twentieth century American realism. (shrink)

Roy Wood Sellars (1880–1973) is often reduced to his role as father of Wilfrid Sellars. This is unfair because during the 1920s, ‘30s, and ‘40s, Roy Wood was one of the leading figures of the then prevailing American realist movement. In the present paper, I will focus on one particular facet of R. W. Sellars’ philosophical approach: his continual examination of Albert Einstein’s special theory of relativity. I shall primarily reconstruct his discussion of Einstein’s theory, as it can be found (...) in his seminal The Philosophy of Physical Realism (1932). In contrast to authors such as Bertrand Russell or Émile Meyerson, Sellars refused to interpret special relativity in a realist vein. In his view, it should be seen as an “ars mensurandi” and thus being interpreted purely operationally. As with Einstein himself, the concept of simultaneity was his paradigm case in point. However, Sellars opined that besides the physical (mensurational) concepts of time and simultaneity there also exists an ontological understanding of these notions. “Real” time and “absolute” simultaneity are, according to Sellars, the indispensable non-relativistic counterparts to Einstein’s respective relativistic conceptions. They are to be interpreted realistically since they prove, Sellars maintains, to be explanatory regarding events in Einstein-Minkowski’s world. In the course of the paper, I shall compare this view with the one defended by Henri Bergson. Furthermore, Sellars’ later approach from the 1940s and ‘50s will be briefly considered and critically discussed by confronting it with more recent attempts at ontologically ‘grounding’ special relativistic kinematics.

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 paper scrutinizes and chronologically reconstructs Hans Vaihinger’s impact on contemporary Kant research. It provides an account of his engagement at both the exegetical and the institutional level. More broadly, it allows us to appreciate – for the first time, and in a comprehensive way – Vaihinger’s significance to the assessment of Kant’s legacy.

Eino Kaila's thought occupies a curious position within the logical empiricist movement. Along with Hans Reichenbach, Herbert Feigl, and the early Moritz Schlick, Kaila advocates a realist approach towards science and the project of a “scientific world conception”. This realist approach was chiefly directed at both Kantianism and Poincaréan conventionalism. The case in point was the theory of measurement. According to Kaila, the foundations of physical reality are characterized by the existence of invariant systems of relations, which he called structures. (...) In a certain sense, these invariant structures, he maintained, are constituted in the act of measuring. By “constitution”, however, Kaila meant neither the dependency of the objects of measurement on a priori concepts (or Kantian categories) nor their being effected by conventional stipulations in a Poincaréan sense. He held that invariant structures are, quite literally, real: they exist prior to and independently of our theoretical capacity. By executing measurements, invariant structures are detected and objectively determinable by laws of nature. (shrink)
