Concerns the sociophilosophical and cultural analysis of Valerian Muravyov’s heritage (1885-1930). He was a Russian cosmist of the “second generation” and the author of ideas that were original in his times and are novel still challenging the contemporary world outlook. Those ideas are gradually penetrating into the scientific discourse thus becoming an asset of the Russian and global intellectual environment. The author reveals the content and universal cultural significance of the main Muravyov’s intentions including his outlines of hypostatic logics and anthropological mathematics, images of the social conciliar­hypostatic All, the idea of the recurrence of the Entity, and other. Muravyov’s approaches to the perfection of a human being together with the major tracks of the cultural evolutionary ascent of the Homo sapiens are also examined. The author makes an attempt to comprehend holistically Muravyov’s heritage and theoretically codify it within the context of the contemporary world outlook revealing the general logic and internal contingency of his cosmistic thoughts and ideas. The author argues that Muravyov’s insights go with the trend of historically veridical scientific and technological progress of humanity and that they are fully consistent with the trends in the development of information technologies.
