This paper considers how to best relate the competing accounts of scientific knowledge that Russell and Reichenbach proposed in the 1930s and 1940s. At the heart of their disagreements are two different accounts of how to best combine a theory of knowledge with scientific realism. Reichenbach argued that a broadly empiricist epistemology should be based on decisions. These decisions or “posits” informed Reichenbach’s defense of induction and a corresponding conception of what knowledge required. Russell maintained that a scientific realist must (...) abandon empiricism in favor of knowledge of some non-demonstrative principles with a non-empirical basis. After identifying the best versions of realism offered by Reichenbach and Russell, the paper concludes with a brief discussion of the limitations of these two approaches. (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)

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)

In The Philosophical Criticism, Alois Riehl developed a realistic interpretation of Kant’s transcendental idealism based on his theory of space and time. In doing so, more than 100 years ago, he formulated an interpretation of the relation between the thing in itself and appearances that is discussed in current research as the metaphysical „dual aspect“ interpretation, although it is rarely attributed to Riehl. To reconstruct Riehl’s position, the research results of comparative studies on Moritz Schlick are systematically extended and applied (...) to the current debate on Kant’s transcendental idealism.
