John Dewey’s theory of truth is widely viewed as proposing to substitute “warranted assertibility” for “truth,” a proposal that has faced serious objections since the late 1930s. By examining Dewey’s theory in its historical context – and, in particular, by drawing parallels with Otto Neurath’s concurrent attempts to develop a non-correspondence, non-formal theory of truth – I aim to shed light on Dewey’s underlying objectives. Dewey and Neurath were well-known to each other and, as their writing and correspondence make clear, (...) they took similar paths over the mid-century philosophical terrain. I conclude that Dewey’s account of truth is more principled, and more relevant to historical debates, than it first appears. (shrink)

Many commentators on Alfred Tarski have, following Hartry Field, claimed that Tarski's truth-definition was motivated by physicalism—the doctrine that all facts, including semantic facts, must be reducible to physical facts. I claim, instead, that Tarski did not aim to reduce semantic facts to physical ones. Thus, Field's criticism that Tarski's truth-definition fails to fulfill physicalist ambitions does not reveal Tarski to be inconsistent, since Tarski's goal is not to vindicate physicalism. I argue that Tarski's only published remarks that speak approvingly (...) of physicalism were written in unusual circumstances: Tarski was likely attempting to appease an audience of physicalists that he viewed as hostile to his ideas. In later sections I develop positive accounts of: (1) Tarski's reduction of semantic concepts; (2) Tarski's motivation to develop formal semantics in the particular way he does; and (3) the role physicalism plays in Tarski's thought.

The aim of the paper is to consider the narrative that Philipp Frank’s decline in the United States started in the 1940s and 1950s. Though this account captures a kernel of truth, it is not the whole story. After taking a closer look at Frank’s published writings and at his proposed book, one can see how he imagined the reunion of logical empiricism. His approach was centered on sociology and on the sociological aspects of science and knowledge. As I will (...) argue, Frank’s longstanding interest in the reunion of the sciences and the humanities can be detected in his sociology and philosophy of science as well as in his reading of Carnap’s critique of metaphysics. But Frank’s intention was never fully recognized, partly due to the atmosphere of American philosophy and sociology in the second half of the twentieth century. As a result, his conception of unified science and logical empiricism died with him. (shrink)
