This concluding chapter assesses Thomas Kuhn’s philosophical legacy, characterizing his career as fundamentally tragic: he sought philosophical respectability but achieved notoriety instead, becoming forever associated with relativist interpretations he neither intended nor endorsed. The chapter argues that Kuhn’s lack of formal philosophical training—symbolized by his post-war decision not to pursue philosophy courses—left him unable to fully articulate or defend the implications of The Structure of Scientific Revolutions. Drawing on speculative history of science rather than traditional philosophy, Structure revolutionized the discipline by demolishing logical empiricism’s ahistorical approach, yet Kuhn spent subsequent decades retreating from his most radical claims. Under sustained criticism, he progressively domesticated his key concepts—particularly incommensurability— culminating in a late-career Kantian linguistic turn that abandoned the naturalism and historical methodology that made Structure compelling. The chapter suggests Kuhn painted himself into a philosophical corner from which his unfinished Plurality of Worlds showed little prospect of escape. Ultimately, Kuhn emerges as a reluctant revolutionary who transformed philosophy of science while remaining perpetually uncomfortable with that achievement, seeking unsuccessfully to achieve the philosophical respectability that his most important work paradoxically denied him. Despite this personal failure, his core insights—normal science, exemplar-based learning, and the social-historical constitution of scientific practice—remain fundamental contributions that justify regarding him as genuinely revolutionary, even if he never wished to be.
