The article is devoted to the search for the optimal path of controlled techno-bio-socio evolution, which will pre-serve the humanity’s traditional constants. Based on the previously conducted research, the author argues that compliance with the principle of continuity is possible only if the program of moderate transhumanism, which involves a delicate modernization of human nature while preserving its essence, is implemented. A similar transhumanist narrative is also evident in early 20th-century Russian scientific thought. The conducted compara-tive analysis of the main provisions of Russian philosophy of the Silver Age and the philosophy of moderate transhumanism allows us to assert that they coincide in terms of determining the limits of redesigning human nature. The humaneness and ethical elaboration of the ideas of Russian thinkers provide grounds for their use as socio-cultural guidelines for the philosophy of moderate transhumanism. The methodological basis of the study is the principles of systemic and comparative historical approaches. According to the author, these princi-ples enable the achievement of a synergistic effect, thereby enriching the concept of moderate transhuman-ism.
