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)

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

In their early epistemological writings, Cassirer and Schlick represent two different strategies in their revisionist approaches toward the original Kantian doctrine. While Cassirer attempts a revision in the sense of ‚critical idealism‘, Schlick attempts a revision in the sense of ‚critical realism‘. It will be shown that this contrast in programmatic outlook leads to significant divergences, especially in the respective theories of space and the correlated interpretations of Einstein's general theory of relativity. On the whole, it will be argued that (...) Schlick ‚won out over‘ Cassirer in the end, but only by leaving almost completely the boundaries of the original Kantian epistemological project. (shrink)

Structure is the connecting link between the early epistemologies of Cassirer, Schlick, and Carnap. However, there are important programmatic differences among Cassirer’s, Schlick’s, and Carnap’s articulations of the structuralistic point of view. Whereas Cassirer hoped to argue in favor of an ‚idealist‘ and Schlick in favor of a ‚realist‘ conception of structure, Carnap thought it possible to remain neutral in this respect. I will argue that Carnap’s approach, though at first sight promising, was doomed to failure precisely because of its (...) base in ‚neutralism‘. In order to distinguish mathematical from physical structures, a certain form of realism is necessarily required. (shrink)

Pierre Duhem gilt ais einer der wichtigsten Reprüsentanten der franzosischen Wissenschaftsphilosophie um 1900. Seine Konzeption physikalischer Theorien wird üblicherweise ais moderne Umsetzung des antiken – proto-positivistischen – Programms der „Rettung der Phänomene‟ angesehen. Diese Sicht ist richtig, bedarf aber der Ergänzung, indem der diskursive Kontext der Duhemschen Position berücksichtigt wird. Im vorliegenden Beitrag wird dargelegt, dass Duhems philosophischer Zeitgenosse Abel Rey eine zentrale Rolle in diesem Zusammenhang spielte.

Hans Reichenbach’s position in the debate over scientific realism is remarkable. On the one hand, he endorsed the programmatic premises of logical empiricism; on the other, he explicitly employed a realist approach to conceptions such as reference, causality, and inference to the best explanation. How could that work out? It will be shown in the present paper that in Reichenbach’s view scientific realism is not, as frequently assumed, opposed to logical empiricism but rather to logical positivism. A distinction without a (...) difference? Not at all, at least for Reichenbach. As is well known, his particular—probabilistic—variant of logical empiricism was intended to circumvent what he considered the shortcomings of the Vienna Circle’s verificationist approach to the language of science. In Experience and Prediction, Reichenbach became most explicit in this regard. However, I shall argue that his position remained notoriously unstable in the end. It oscillated between a full-fledged scientific realist reading and an eminently pragmatist reading. Nevertheless, Reichenbach’s contribution proved instrumental in preparing subsequent efforts at reconciling logical empiricism and scientific realism. (shrink)

This article considers the evolution of Feigl's attempt at establishing a stable form of scientific realism. I will argue that Feigl's work in that area should be appreciated for two reasons: it represents a telling case against the view of there being an unbridgeable ‘analytic-continental divide’ in the context of twentieth-century philosophy; it contradicts the idea that scientific realism is at odds with logical empiricism. It will be shown that Feigl developed his scientific realist position from within the logical empiricists’ (...) Vienna Circle. This, in turn, necessitates a fresh approach toward the contemporary scientific realism debate. (shrink)
