Personality is one of the main elements in the structure of a novel; because this element participates in its events, whether negatively or positively, and it is one of the narrative techniques on which the novel is based and is considered a factor of its success, distinction, and immortality. Among the types of personalities, the role of the hero or protagonist, as the most prominent element, also excites and stimulates the reader's emotions throughout the novel and creates synergy and convergence with the audience. The actions of the novel are centered on the protagonist's role, to the extent that it overlaps with other influential characters; therefore, in the present study, an attempt is made to investigate the components of the protagonist's personality and to recognize its dimensions in Rabee Jaber's novel "Al-I'tirafat" based on Eysenck's personality theory, using a library method and relying on a descriptive-analytical method. A novel whose events revolve around "Maroun," a character who experienced the Lebanese civil war and reveals his inner conflicts from which he suffers. The main goal of this article is to examine the typology of the character of "Confessions" based on this theory, a theory that analyzes and examines temperaments in three types of introverted, psychotic, and neurotic. These three dimensions provide a framework that enables us to understand personality traits and encourages us to better reveal their complexities. The achievement of the research indicates that due to the tense atmosphere derived from the Lebanese civil war, the presence of the main and influential character of the novel has a shaky and abnormal identity and is faced with an internal and identity crisis that has no fate other than darkness and misery. Based on Eysenck's personality theory, the index of neuroticism and introversion has the highest frequency compared to other components, such as extroversion and psychosis, which play an enigmatic role. The most important signs of neuroticism are imbalance in behavior, mental confusion caused by past bitter events, confession of guilt or remorse, and signs of introversion, anxiety, feelings of inadequacy and worthlessness or constant inferiority in daily life, and signs of psychosis include lack of concentration, memory weakness, and stagnation and lack of adaptation to environmental changes.
