This essay explores the contention that posthuman subjects, such as androids, clones, and robots, can experience psychological trauma. The aim of the paper is to examine this notion in three science fiction texts: Mary Shelley’s Frankenstein, Philip K. Dick’s Do Androids Dream of Electric Sheep?, and Ursula K. Le Guin’s short story ‘Nine Lives’. What these narratives illustrate is that trauma manifestations can contribute to a disruption of ontological frameworks that maintain categories such as ‘human’ and ‘non-human’ as permanent and distinct. As a result, it might be argued that these texts undermine anthropocentrism and invite a reconceptualising around the term ‘human’, but also around trauma, conventionally understood as a primarily human experience. Science fiction is thereby a significant genre when it comes to questioning anthropocentric perspectives. Using posthuman theory and trauma studies, this essay argues that these three texts portray their respective posthuman subjects as trauma victims, and further that they demonstrate how the experience of trauma carries with it the potential to bridge the gap between human and posthuman through the act of bearing witness to one another’s trauma.
