The article examines the phenomenon of doubling in its historical and semantic dynamics – from archaic conceptions of the multiplicity of the soul to contemporary technotronic forms of digital twins. The relevance of the study is determined by the need to rethink the structures of human identity in the context of the rapid development of neural networks, which generate new types of reflected selves. Doubling is considered as a fundamental anthropological constant that expresses culturally conditioned models of personality fragmentation. The novelty of the approach lies in the reconstruction of the semantic and historical halos surrounding the key names of the double – from the Egyptian Ka and Ba to contemporary “avatars” and “digital twins.” The study demonstrates that the modern digital twin is not a fundamentally new phenomenon but rather a technological transformation of ancient representations of the human being’s external or internal reflection. The analysis leads to the conclusion that the phenomenon of doubling functions as a universal mechanism of cultural self-reflection. The contemporary digital environment reintroduces multiplicity, but on a new level – the level of a distributed, fragmented, and algorithmically supported self. This opens new hermeneutic perspectives for interpreting doubling, including the problem of the mirror.
