There are works of V. V. Bibikhin, V. M. Rozin, N. V. Medvedev, E. B. Borisov that are studied in the article. There are some common places in Heidegger’s and Wittgenstein’s philosophy: 1. The lack of tendency to prove something; 2. The criticism of descriptivism; 3. The disposition to practice, not theory; 4. Non-systematical style of philosophizing; 5. Symbolic understanding of language and world; 6. The search of eidetic access to language. But the main difficulty of the comparative study is the lack of common conceptual field between Heidegger and Wittgenstein. So the more general perspective of eidetic epistemology of language is proposed. There is the possibility to make our comparisons of Heidegger and Wittgenstein wider.
