http://dx.doi.org/10.5007/1808-1711.2012v16n1p99 This paper presents a possible but controversial characterization of two periods in Rudolf Carnap’s work: foundationalism and anti-foundationalism. I will argue that even with the identification of two periods, it is possible to argue in favor of the unity of Carnap’s work concerning the unity of science and the principle of linguistic tolerance. To do so, I will count on the analysis of some revisionist views advocated by Friedman and Uebel. Therefore I intend to contribute to a discussion that, (...) since the second half of the twentieth century, seemed to have been overcome, but that, at the end of that century is resumed due to the importance of issues such as the unity of science, observability and interpretation of the scientific language for the philosophy of science.

When Schlick introduced his theory of ”Konstatierungen“ in the Vienna Circle’s Protocol-Sentence Debate, the sole other member of the Circle who took part on his side was his former disciple B´ela Juhos. However, Juhos’ own conception, developed in full extend only later, differs in important respects from the one of his teacher. Both conceptions are critically examined in the first part of this paper. The second part is devoted to an examination of the charge that such basic propositions are by (...) all means useless because of incommunicability. (shrink)

Philipp Frank––physicist, philosopher, and early member of the Vienna Circle––is often neglected in retrospective accounts of twentieth century philosophy of science, despite renewed interest in the work of the Vienna Circle. In this thesis, I argue that this neglect is unwarranted. Appealing to a variety of philosophical and historical sources, I trace the development of Frank’s philosophical thought and, in so doing highlight the roles played by history, sociology, values, and pragmatism in his philosophy of science. Turning to contemporary literature, (...) I then argue that Frank’s work should be understood as an early instance of what is now called “socially engaged philosophy of science.” This understanding is explored through a careful consideration of his work on education, where previous work on history, sociology, values, and pragmatism is applied to an important, real-world problem. This socially engaged reading of Frank extends beyond pragmatic issues of theory application, because as I show, Frank used sociology to argue for the meaningfulness of metaphysical claims. However, Frank’s account of meaning may seem to be problematic since it heavily relies on Percy Bridgman’s operationalism. So, I outline the problems associated with Bridgman’s account of operationalism and show that Frank’s view does not fall prey to the same criticisms. After these objections are addressed, Frank’s work is contextualized in the broader debate about value-free science, where I argue that Frank did not endorse the value-free ideal. As a result of these findings, we will not only have a clearer picture of Frank’s philosophical contributions, but also a better understanding of how the philosophy of science can better engage important social issues.
