Kuhn argues that while revival scientific paradigms are incommensurable claims they are incompatible as well. This brings about a problem: how two incommensurable theories could be incompatible? Incommensurability entails that two rival theories should have different cognitive domain and taxonomic structure, this expression then blocks the emergence of contradiction among statements. In this essay we intend to propose a semantic theory and distinct two kinds of incompatibility, sentential incompatibility and taxonomic structural incompatibility, and thereby attempt to defend incompatibility and incommensurability of paradigms.
