L. J. Ginsburg's book "On Psychological Prose," first published in 1971, constitutes a dilogy with her famous work on lyrics (1964; 3rd ed. - Intrada, 1997). The author considers in it the most important aesthetic and historical-literary problems: the interaction of literature and history, the ratio of fiction and document, everyday personality and literary tradition. The material covered in the book extends from the memoirs of Saint-Simon (XVII - early XVIII century) to the novels of L. N. Tolstoy and M. Proust. Both books by L. Ya. Ginzburg were included in the golden fund of Russian literary criticism and are of keen interest both for those studying the theory and history of literature, and for all connoisseurs of the artistic word.
