This paper examines Kazuo Ishiguro’s The Remains of the Day using Walter D. Mignolo’s decolonial ideas of territorial epistemology and border thinking. Most of Ishiguro’s works, except for those from his earlier Japanese phase, have been confined to Western locations, thus making it difficult to determine whether his works are a challenge to Eurocentric values. The paper positions Stevens’s story within a hierarchical space that fits Mignolo’s territorial epistemology of dominant center and marginal periphery; “ladder” and “wheel” are used metaphorically to illustrate the power of Darlington Hall and Stevens’s commitment to the code of ethics of the aristocracy, all of which contribute to the existence of a closed system of epistemology that promotes the naturalization of social inequality and the exclusion from access to alternative knowledge. Stevens’s interactions with Miss Kenton, Harry Smith, and Mr. Cardinal also show his refusal to engage in border thinking, as he refuses to consider any view that could threaten the pre-existing source of authority. Although the author reflects on these problems through Stevens’s feelings of regret, it provides the reader with an understanding of how socially created hierarchies create moral blindness. Stevens’ late recognition of his misguidance does not lead to genuine border thinking but rather to what Mignolo calls rewesternization—a transfer of loyalty from one master to another that leaves the underlying structure of hierarchy and service intact, revealing how even regret and learning can be co-opted into reproducing the very systems they appear to question.
