Purpose. The paper seeks to prove the thesis of the significance and importance of the theories and methodological approaches of historical anthropology, which are aimed at understanding the meanings, essence and value systems of human existence in the past for philosophical anthropology. The study of this problem is relevant for understanding the evolution of human identity with philosophical and anthropological concepts, understanding the essence of one’s own existence and attitude to the world. Theoretical basis. The author conducts research in the analysis of the reflexive field of philosophical anthropology and related disciplines, in particular historical anthropology, implemented in the philosophical literature of recent centuries, that is, in the space of non-classical and modern philosophical thought. Originality. I raise and substantiate the theoretical question of the scientific significance of the analysis of human existence in the past thanks to the involvement of theoretical approaches and concepts formed in the reflexive field of modern historical and anthropological research. This forms the prerequisites for understanding complex and interdisciplinary explorations of the essence and cultural and spiritual values of human existence. I analyse the problems of the work in the context of the concept of the incompleteness of the project of philosophical anthropology without its involvement in the theoretical achievements of historical-anthropological investigations. Conclusions. In my opinion, modern historical and anthropological studies of the essence and meanings of being a person of the past form an extensive theoretical system. It is realized through such theoretical aspects of comprehension of human existence by historical and anthropological studies as "history of mentalities", "microhistory", "history of women", "new cultural history", "history of identity", "history of memory", history of mental aspects of political processes. Methodological approaches and concepts of modern historical anthropology form the basis of mental reconstruction and understanding of the mental and cultural causes and factors of human existence, thanks to the analysis of the evolution of the worldview, behaviour, outlook, various forms of individual and social activity of the individual.
