This article offers a comprehensive poetic and literaryphilosophical analysis of the character Mr. Crane in British science fiction writer Neal Asher’s novel “Brass Man”. Mr. Crane, a cyborg figure that straddles the boundary between the technological and the biological, serves as a compelling embodiment of posthuman identity. The study investigates the dynamics of his humanization throughout the narrative and contextualizes his transformation within broader theoretical frameworks, including posthumanism, the cyborg concept, and the ethical dimensions of artificial intelligence in literature. By conducting a detailed textual analysis, the article illustrates how Mr. Crane is initially constructed as an “inhuman” brass automaton—an archetypal monster devoid of emotion or empathy— yet gradually evolves into a more complex, ethically nuanced figure. His hybrid nature allows for the exploration of identity, agency, and moral consciousness in speculative fiction. The findings of the study shed light on the poetic and symbolic functions of AI and robotic characters in science fiction, and demonstrate how such figures contribute to rethinking humanity and ethical subjectivity in the context of technological evolution. Ultimately, the article contributes to the growing body of scholarship that examines the intersection of literature, philosophy, and emerging technological paradigms.
