Resumen: In this paper I examine Thomas Kuhn’s epistolary and in-person exchanges with Richard Rorty, and their significance to the former’s work on the nature of scientific development during the years 1976–1986. Accordingly, it corresponds to a significant evolution of Kuhn’s thought from the position expounded earlier in The Structure of Scientific Revolutions. These letters show how Kuhn’s philosophy of science evolved towards a greater emphasis on a key aspect of his former work—the nature of ‘the essential tension’—and that his more linguistically-oriented perspective in these latter years has that emphasis as its goal—at least as a significant part.
