Introduction. The article examines digital epistemology as a factor transforming social philosophy under conditions of the algorithmization of knowledge and the platform-based organization of sociality. Digital technologies change not only the forms of knowledge production and verification but also the conditions of social being within which knowledge acquires normative force. Algorithms, databases, and network infrastructures function as epistemic mediators of selection, ranking, and legitimation, thereby shifting the analytical focus from classical categories of subject, action, and institution to distributed epistemic processes and hybrid agencies. On this basis, the boundary between the social and the technical is problematized, and the role of computational procedures in shaping regimes of visibility, relevance, and trust is clarified. The aim of the article is to demonstrate how the concept of digital epistemology redefines the subject matter and method of social philosophy by revealing algorithmic mediation as a condition of contemporary knowledge and sociality, as well as a factor of power and inequality.
