Abstract
<jats:p>The monograph is devoted to the consideration of the philosophy of the 20th century Russian thinker Nikolai Onufrievich Lossky from the perspective of the concept of "logical and epistemological unity". This means that the author of the study takes into account all integral forms of Russian thought and shows Lossky's philosophy precisely from the standpoint of the unity of logic and epistemology. The monograph examines the socio-cultural origins of the evolution of Lossky's views, the concept of intuitionism, the thinker's logical research, his concept of the history of Russian philosophy, and the epistemology of Russia. The book also contains a description of various concepts of the thinker's students and followers. Recommended for historians of Russian philosophy, as well as for anyone interested in philosophy.</jats:p>
