From shared stimuli to preestablished harmony: the development of Quine’s thinking on intersubjectivity and objective validity

W. V. O. Quine is generally seen as one of the foremost empiricists of the twentieth century. For large parts of his career, the label “empiricist” is accurate; in his mature work, however, he integrated decidedly antiempiricist elements in his epistemology. From The Roots of Reference onward, he enlists natural selection and innate cognitive structures to ensure that scientific concepts have a “degree of objective validity.” From From Stimulus to Science onward, he also explains the very possibility of communication via a preestablished harmony of innate cognitive structures that is guaranteed by natural selection. This article reconstrues the reasons that compelled Quine to these commitments, and it details the development of Quine’s thinking on these topics across more than 3 decades; in particular, the article argues that recognizing that so-called stimulus meanings are private decisively shaped Quine’s views. By means of a critical evaluation, the article argues that natural selection can make plausible that scientific concepts have a degree of objective validity—if this Quinean claim is properly understood; in contrast, the article suggests, with recourse to research by Robert C. Richardson, that it is doubtful whether natural selection can underpin the preestablished harmony that Quine requires to explain communication

A science-based critique of epistemological naturalism in Quine’s tradition

At the intersection of epistemology, metaphilosophy, and philosophy of science, this exciting new book examines the epistemic limits of empirical science. It makes a unique contribution to research on epistemological naturalism in Quine’s tradition by criticizing the position based on first-order data from empirical psychology and the history of natural science. This way, it meets the naturalist on their own ground not only regarding subject matter, but also regarding their epistemic methods. The book explores the works of a variety of philosophers in the field, including W. V. Quine, Penelope Maddy, Tyler Burge, Stathis Psillos and Howard Sankey. By carefully considering experimental results from behaviourism as well as developmental and perceptual psychology, Gubelmann finds that none of these disciplines can furnish the epistemic means to successfully naturalize the central cognitive preconditions of scientific theorizing. Furthermore, Gubelmann presents novel arguments for the claims that epistemological naturalists are committed to scientific realism, and that they are unable to defend this position. Based on these results, Gubelmann concludes that epistemology is not part of empirical science, which directly contradicts epistemological naturalis
