Discussions about language caused these thinkers to take analytical and critical positions towards each other. Habermas, with the criticisms he made to two philosophical traditions, hermeneutic and analytical; He has established his pragmatist position on language.By following the works of Habermas, it becomes clear that the origin of his interest in language should be considered in "Humboldt's linguistic theory".

The origin of Habermas's "linguistic turn" is rooted in Humboldt's linguistic theory, a thinker who is on the fringes of the philosophical stream, but by highlighting his linguistic theory, Habermas shows that the interpretation and understanding of the two main thinkers of twentieth century linguistic thought,namely Heidegger and Wittgenstein about language can be analyzed in Humboldt's three-level division.
