Modernist literature (ML) is a literary movement that first appeared in the late 19th and early 20th centuries. It is distinguished by an acute departure from conventional narrative structures and a significant focus on the investigation of personal awareness and Deconstruction of Subjectivity (DS). This study analyzes the complicated connection between ML and Immanuel Kant's explanation of the philosophical idea of DS. ML developed in the late 19th and early 20th centuries broke conventional narrative norms and put a significant emphasis on exploring personal subjectivity and knowledge. This study addresses that ML and Kantian philosophy interact in-depthly, combining the divide between the disciplines. This analysis explains that the results deconstruct subjectivity, requiring readers to reconsider their views of reality and identity in a constantly changing world, by evaluating significant texts from European and American literature that are part of the ML and DS. Concerning ML and its fascinating dialogue with Kantian philosophy and the standards of European and American literature offers insightful perspectives on the development of literary conceptualization. In addition, it promotes a more in-depth comprehension of the enduring concerns that surround human consciousness and perception, resonating with modern discussions in the fields of philosophy, psychology, and literary theory.
