Abstract: This article analyzes the problem of existential grounds of human identity in the context of technocratic challenges of modern era, among which are: temporality, ectaticism, connectedness of individual being with being of the Others. Attention is given to the existential meanings of mortality and temporality of the Other, which lie in the ontological moods of pain and anxiety. Such moods are defined as the ground of the genuine in various sociocultural identification. The specificity of modernity is determines within the framework of M. Heidegger’s philosophy of technology, in other words, the dominance of a particular way of human existence – Gestell. The anthropological risks along with the challenges of modern era are viewed as a possible enframed attitude towards any self-identifications. In the theoretical-methodological aspect, the article is based on the critical interpretation and evolution of M. Heidegger’s ideas associated with the project of existential analytics and philosophy of technology. The scientific novelty consists in application of the theoretical-methodological principles of Heidegger’s philosophy to the problem of human identity, which allows its examination from the existential perspective. At the same time, ontologically are viewed not only the moods originated by the fact of personal mortality, but also the fact of mortality of the Other.
