This paper examines the hierarchical organization of principles in soil science, emphasizing their continuity with classical positions from various scientific fields and their role in integrating theory and practice. The study highlights differences in the genesis of principles, ranging from theoretical generalizations to experimentally validated propositions. Special attention is given to ideas of V.I. Vernadsky and V.V. Dokuchaev, who laid the foundations for the systemic and evolutionary-historical approaches to soil study. It is demonstrated that the scientific worldview serves as the pinnacle of this hierarchy, defining a system of generalizations, including the principles of systemicity, historicism, and the primacy of scientific approaches formulated by Academician G.V. Dobrovolsky. These principles ensure unity between theoretical and applied directions, rooted in the classical supra-conceptual ideas by V.V. Dokuchaev, whose works underpin the genetic approach to soil study. Within the hierarchy, following the scientific worldview come methodological principles neutral to specific disciplinary sections, followed by concepts, laws, and principles. For instance, N.M. Sibirtsev’s genetic principle, formulated in the 19th century, continues to define approaches to soil genesis. The paper underscores the importance of continuity, showing that Dokuchaev’s principles of systemicity and historicism remain fundamental for developing new scientific leads. The hierarchical organization of principles and their intra- and interdisciplinary continuity serve as key instruments for the progress in soil science, enabling integration of diverse knowledge into a unified scientific field. The necessity for further systematization of principles, particularly in biogeochemical cycles and interdisciplinary research, and terminology harmonization to strengthen the link between theory and practice is also emphasized.

To mark the 160^th anniversary of V.I. Vernadsky's birth, Lomonosov Moscow State University has organized an exhibition based on the theme of “living matter”, which to a greater or lesser extent permeates all the geospheres of our planet, provides many mechanisms of interaction between the geospheres and links between the planet and the cosmos. Natural exhibits demonstrate peculiarities of the geochemical transformation of individual organisms and their communities during the transition from the biosphere to the lithosphere, the diversity of biocosmic bodies in the history of our planet, the possibilities of modern sciences in reconstructing geobiosystems of the past. The structure of the exhibition includes a number of special blocks containing original exhibits and information, namely: “Scientist’s Cabinet” with information about the life path, scientific directions and some students and followers of Academician V.I. Vernadsky (connected to him through Moscow University). The cluster “Co-evolution of the Biosphere and Lithosphere” with disclosure of the mechanisms of transition of living matter and integral ecosystems into the “stone record” of the Earth, the structure of the pedosphere in a broad sense, the diversity of biogeoprocesses and their products in the history of the Earth, the formation of “archives of nature” in the geospheres, the functioning of geobiodynamically active zones on the example of the East European Platform; the cluster “University’s Lukomorye”, reflecting peculiarities of coastal geo-ecosystems for the general public (on the example of the Paleocene of the Volga region). Most of the exhibits of the exhibition have been obtained during the scientific and educational expedition “Flotilla of Floating Universities” (2015–2022) from the Volga region, the Caspian Sea, the Don region and the Urals and are considered in the future as the basis for the development of a model polygon of the “MSU Youth Museum”.
