In literature, psychological fiction (also psychological realism) is a narrative genre that emphasizes interior characterization and motivation to explore the spiritual, emotional, and mental lives of the characters. The mode of narration examines the reasons for the behaviors of the character, which propel the plot and explain the story. Psychological realism is achieved with deep explorations and explanations of the mental states of the character's inner person, usually through narrative modes such as stream of consciousness and flashbacks.
The psychological novel has a rich past in the seventeenth- and eighteenth-century works of Mme de Lafayette, the Abbé Prévost, Samuel Richardson, Jean-Jacques Rousseau and many others, but it goes on being disinvented by ideologues and reinvented by their opponents, because the subtleties of psychology defy most ideologies.

[The Tale of Genji, as translated by Arthur Waley,] is written with an almost miraculous naturalness, and what interests us is not the exoticism — the horrible word — but rather the human passions of the novel.
