The paper is devoted to the comparison of notions of difference by Heidegger and severance by Levi-Strauss. A possibility of comparison is caused by a broader context of the notion of structure however it is used by Heidegger and Levi-Strauss in various intellectual projects: Dasein analysis by the former and anthropologic investigations by the latter. The author proves that most contemporary French philosophers address the problem of structure by Heidegger through a prism of structural anthropology of Levi-Strauss.
