Until now, this problem has not been sufficiently studied in Russian psychology. The book describes implicit and scientific ideas about conscience, its nature, role and functions. Questions about the sense of duty, the emotion of guilt and remorse, and various aspects of the experience of shame are considered. In addition to an analysis of the literature on this issue, the book provides an extensive bibliography, as well as methods for studying conscience, guilt and shame. The publication is intended for psychologists, teachers, sociologists, specialists in interpersonal relations, as well as for students of university faculties of relevant profiles.
