The study focuses on the relationship between the ethics of reading and the narrator’s unreliability in the novel by Kazuo Ishiguro The Remains of the Day. Drawing on James Phelan’s research, the authoress states that unreliability that can be attributed to the narrator of Ishiguro’s novel can be classified as either an error of being in the wrong or withholding some information consciously. Consequently, six types of unreliability can be distinguished: misreporting, misinterpreting, misevaluating, underreporting, underinterpreting, underevaluating. Employing these categories, the authoress analyses a literary text and lists different types of unreliability which are characteristic of Stevens, the main character and the narrator in Ishiguro’s novel.
