Purpose of the study: The purpose of the study is to identify the originality and ideological functional status of the ethnomental component in the works of F. Dostoevsky. Methods: The work integrates a complex of modern approaches and methods, mainly focusing on the ideas and principles of the traditional, cultural and historical method, which demonstrates the general cultural, sociological, and psychological aspects of the study of Dostoevsky’s literary heritage. The typological method has contributed to the literary clarification of the ethnomental components in fiction and journalism of the writer. The narratological approach is used to analyze the narrative structure of Dostoevsky’s works, the correlation of the writer’s and other people’s speech, to identify various points of views on the problem, and to establish the ambiguity of the writer’s position. The contextual analysis allowed analyzing the images of characters, first, within the local context and, second, within the macrocontext, which includes other literary sources, appropriate comparisons and build a verification model of the study. Main results: The analysis of the writer’s life, his philosophy of life, sacrifices, social ambivalence, predisposition to reflection, etc. suggests the presence of certain mental foundations. The main ideas, attitudes, spiritual discoveries of the artistic worlds created by the writer are determined by the ethnomental basis of his worldview. This makes it possible to determine and understand the originality and uniqueness of Dostoevsky in the context of Russian literature. Application of the study: The conclusions of the study can serve as the basis for an accurate idea of the correlation of the writer’s worldview and his work. The materials and conclusions of the study can be used in university courses on the history of Russian literature, in special courses and special seminars on the works of Dostoevsky, for term papers, graduation papers, and dissertations. The scientific novelty of the study lies in the fact that the ethnic component in the ideological and artistic system of Dostoevsky who was a Pochvennik writer (i. e. belonged to the Pochvennichestvo movement) was first considered in the context and through the prism of both the life experience of the writer himself and the general anthropological orientation of the writer as well as his understanding of human nature. This study provides not only the opportunity to analyze the ethnic identity of Russian literature but also to trace the influence of the ethnic mentality of Dostoevsky on his worldview embodied in his fiction.
