The book "Incommensurability and Related Matters" brings together some of the most renowned contributions to the critical examination of the problem of the incommensurability of scientific theories. It addresses a variety of questions arising from this concept, including changes in meaning, the reference of theoretical terms, scientific realism and anti-realism, as well as the rationality of theory choice. Furthermore, it explores the cognitive aspects of conceptual change and the far-reaching implications of incommensurability for cultural differences. The work offers both new perspectives and a retrospective on the historical discussion of this topic in the academic literature.
