There is an argument to be made that one of science fiction’s key concerns is the question of what it is to be human, and that thus a form of (post)humanist thinking lies at the heart of the genre. After all, one school of sf scholarship holds Mary Shelley’s Frankenstein (1818) as the genre’s origin text, dealing prototypically with “the search for a definition of man and his status in the universe” (Aldiss 8; cf. Freedman).
