This paper is based on Lacan’s Three Orders Theory and analyzes the early collection of short stories by stream of consciousness novelist James Joyce Dubliners. Lacan's research is based on Freud's theories of unconsciousness, self, and identity. He believed that the development of a person from infancy to adulthood goes through three processes, namely the Imaginary, the Symbolic and the Real. The three stages or orders of personality development roughly correspond to the needs, wants, and desires that people experience. These three orders exist in three different stages, but they intersect with each other and coexist in the subject. In each stage of the story, James Joyce shows a structure of epiphany to reveal the paralysis of the people and Dublin. This article will be guided by the story and apply Lacan's Three Orders Theory to the psychology of characters at different stages. In summary, characters in the three stages failed to establish successful self-identity; Due to the collapse of their ideal ego and the disillusionment of their ego ideal, their desires are always shattered. Dubliners presents a tragedy destined to fail with a naturalistic feeling. (Chungnam National University)
