Psychoanalysis refers to a set of analytic practices, theories, and concepts focused on the inner workings of the human unconscious, its manifestations, and ailments. A series of texts published towards the end of the nineteenth century and throughout the early decades of the twentieth century have solidified psychoanalysis as a core part of the arts and the collective imagination. Psychoanalytic theories translated into literary works and entered the aesthetics of modernist art movements as intellectuals, artists, and writers sought ways to depict the increasingly discombobulating experience of modernity and, subsequently, the shock and trauma of World War I, as well as a series of geopolitical changes that took place in the first half of the twentieth century.
