In the article, we consider how the empty signifiers influenced the understanding and researches in the structure of philosophical and scientific discourse. Using ideas by M. Foucault and R. Barthes we call meanings of such empty signifiers “voids of meaning” according to their occurrence in both concepts and structures. As an example, we consider papers about the philosophy of science by V.M. Allakhverdov, A.S. Karmin, and Yu.M. Shilkov, and the project of V.M. Allakhverdov’s theory of consciousness. As a result, it was found that the XX-XXI centuries’ trend of mass higher education and a more cardinal specialization among scientific disciplines can lead to the following fact: the content of one discipline may partially become a semiotic myth for representatives of the other one. These results require further conceptual development.
