Abstract: In the most complete collection of I.B. Rodnyanskaya's works, The Movement of Literature, the name of V.S. Solovyov appears more than 50 times in different contexts. The influence of the founder of philosophical criticism on the strengthening of this direction in Rodnyanskaya's works is provided both by theoretical and methodological works ("Beauty in Nature", "The General Meaning of Art", "The First Step to Positive Aesthetics", etc.) and by private literary and critical observations ("The Fate of Pushkin", "Poetry of F.I. Tyutchev", "Buddhist mood in Poetry", etc.). The purpose of this article is to identify and analyze those principles of positive aesthetics that have most influenced Rodnyanskaya's critical method. The absence of a holistic teaching about aesthetics in Solovyov did not prevent the fact that the basic principles were used by Rodnyanskaya in private literary and critical observations. The main conclusions of the study are the data that allow us to talk about the rapprochement of Rodnyanskaya and Solovyov not only at the level of methodology, but also in the aspect of the poetics of literary and critical utterance. Common to Solovyov and Rodnyanskaya should be considered the plot, which consists in solving a problem related to the sphere of spirituality or, in a narrow sense, with the study of the artist's soul. The works of representatives of the philosophical direction of criticism are distinguished by the presence of two time layers.
