Why is Madame de La Fayette’s The Princess of Cleves important to the psychological novel?

Madame de La Fayette’s La Princesse de Clèves (1678) is considered the foundational work of the psychological novel because it shifted the focus of fiction from external action to the internal workings of the human mind.12

Prior to this work, fiction was often characterized by a proliferation of incidental characters and dramatic events. In contrast, La Fayette limited her narrative to a few central figures, allowing for a deep, analytical examination of their motives and emotions. By presenting an intimate portrait of a virtuous woman who suppresses her passion for a nobleman, the novel functions as a study of character rather than a mere story of thwarted love.213

The work is noted for its dignified, unsentimental prose and its profound insight into the theme of deliberately unconsummated love. By prioritizing the analysis of human motivation and the internal struggles of the protagonist, La Fayette established a model that influenced generations of writers, cementing the psychological approach as a primary concern of the serious novelist.132
