Analysis:

Freud's literary theory and traditional theoretical viewpoints basically analyze literature-psychology from another angle. Emphasize people's subconscious and unconscious, and emphasize sexual instinct. He pioneered the study of literature and art from human psychology and history.

Traditional theories, such as Plato's charm theory and inspiration theory, such as distance theory, have at most developed from the perspective of literature and creation to the relationship between man and nature and between man and works.

Of course, they all found that literature and art are mainly a subjective spiritual activity, emphasizing the relationship between literature and spirit. Freud said that it is a great leap in the history of literary theory to explore the meaning of works from people's deepest conscious activities.
