The main part of the book consists of two closely related studies: "Joy and Happiness at Dostoevsky," which addresses the spiritual foundation of the writer's philosophy, and "Dostoevsky and Schiller," which thoroughly, based on the German original text, describes Dostoevsky's creative dialogue with the most important European author for him, under the influence of which his worldview was formed. The content of the book is supplemented by articles of different years, interpreting the psychologism of Dostoevsky's images and his creative connections with the problems of European romanticism.
