Abstract

Over the course of three books—Wandering Significance, Physics Avoidance, and most recently Imitation of Rigor—Mark Wilson seeks to rectify what he takes to be a century of error regarding analytic philoso-phy’s understanding of scientific theorizing. This is largely framed in terms of a sustained attack on what Wilson terms ‘theory T thinking’, which he uses to refer to a melange of philosophical tendencies that he argues fail to do justice to the nuances of how world–theory relations are forged in the physical sciences. In its place, Wilson puts forward an intricate account of the shifting explanatory strategies scientists and mathematicians utilize, strategies that result in the morphing of the semantic import of our scientific terms. In the aftermath an important question emerges: what is to become of scientific realism? Despite numerous pronunciations of his own ‘stout’ realist stance, it remains unclear what Wilson’s position might actually entail. I first sketch Wilson’s disputes with theory T thinking and demonstrate how his rejection of the main tenets of most contemporary realist accounts leaves a question as to what his own realist avowals could mean, further arguing that these are largely attempts to distance himself from any whiff of neo-Kantianism. In the remainder of the article, I turn to discuss a neo-Kantian account that I argue is both complementary to Wilson’s viewpoint and provides a foundation for a post-theory T realism: Ernst Cassirer’s account of concept-formation in the natural sciences. By fleshing out Cassirer’s notion of the transformation of the given and the particular role he attributes to theoretical idealization, I reconstruct his account in a way that draws out a number of fruitful parallels between his philosophy and Wilson’s. The upshot is that a post-theory T scientific realism can plausibly be brought into line with neo-Kantian conceptions.
