1、 Review of intermediary issues

Deeply explored the evolution of the relationship between literature and reality and its core position in Marxist literary theory. With the expansion of literary boundaries and the increasing complexity of reality, research methods have also changed, involving non literary materials such as text, writing, discourse, culture, as well as new issues such as globalization and transnational capital. Jameson's research focuses on the relationship between form and history, emphasizing the importance of intermediaries in dialectics and literary criticism. Tong Qingbing's theory of "two intermediaries" and the development of Chinese cultural poetics, as well as Hegel and Engels' emphasis on the concept of intermediaries, all reflect the crucial role of intermediaries in handling the relationship between literature and reality. The New Criticism and Canonical Theory, as exemplars of mediation theory, demonstrate the combination of content and form. Derrida's "temporality" dimension provides a new perspective for mediation theory. With the development of nation states, the cohesive role of literature has weakened, and traditional literary qualities are facing challenges. Jameson pointed out that the changes in cultural forms in late capitalist societies have challenged the literary ideals of traditional intermediary theory.

2、 Montage

This chapter explores how literary theory in postmodern society addresses the issues of humanistic crisis and aesthetic diffusion, as well as how the expansion of the boundary between literature and reality affects intermediary choices. Walter Benjamin and American New Historicism provided a solution by focusing on the reorganization of cultural and historical materials, abandoning humanistic subjectivity and the concept of complete unity in form, and instead constructing a new medium with traditional rhetorical implications.

3、 Cognitive mapping

Deeply explored Frederick Jameson's mediation theory, particularly how he combined Lucien Goldman's concept of structural homology with Algirdas Grimas' semantic rectangle to analyze character structure and social contradictions in literary works. Jameson further developed the concept of cognitive mapping, drawing on Kevin Lynch's research on urban image, emphasizing the connection between individuals' self positioning and the overall society in late capitalist society. He insists on the concept of totality to understand modernity issues, and believes that cognitive mapping is similar to ideology, helping individuals find their place and class affiliation in capitalist society.

4、 The intermediary of disappearance

In depth exploration of Frederick Jameson's mediation theory and its relationship with subjectivity issues. Jameson's theory was influenced by Althusser's theory of blank subjectivity, which viewed the subject as an absent entity connected to the state apparatus through ideology. Although this viewpoint avoided the flaws of humanism, it failed to address the issue of subject agency. With the development of Lacanian theory, especially the introduction of the real world, the subjectivity theory of post structuralism has become outdated and requires a new paradigm shift. Slavoy Zizek's interpretation of Descartes in "The Sensitive Subject" provides a new perspective on understanding the agency of the subject, arguing that the rational thinking and actions of the subject are the process of the subject's disappearance, rather than the realization of subjectivity.

5、 Conclusion

Jameson's mediation theory introduces active subject mediation through rhetorical montage, structured cognitive mapping, and subjectification process. If this theory is combined with the concept of class, it is expected to realize Lukacs' theory of class practice mediation. Jameson's theory of class is based on Freud's concept of libido, but differs from Freud and Lacan's subjective patterns. His class theory mainly focuses on the United States, without fully considering the global division of labor and cultural relations between the East and the West. The cultural contradictions and class troubles in the process of China's integration into globalization provide practical themes for intermediary theory.
