By positioning an artificial intelligence as the narrative voice, Kazuo Ishiguro´s novel Klara and the Sun opens up a radically different perspective on human existence and the presumed distinctions between human and non-human agents. This article adopts a reception-aesthetic approach to analyze the narrative strategies that allow readers to gain insight into the operational logic and perceptual processes of a black box, Klara, an AI, in the Latourian sense. It examines how the novel‘s unique non-human narrative perspective can prompt readers to reconsider mechanisms of perception and, consequently, to question established conceptions of human identity. The ‘posthuman reading’ advanced in this article proposes a perspective in which existential questions of reality, truth, and humanity are destabilized and reimagined within the interstice of literature, science, and society.
