Kim Stanley Robinson’s novels are attempts at “cognitive mapping,” which Fredric Jameson defines as “a situational representation on the part of the individual subject to that vaster and properly unrepresentable totality which is the ensemble of society’s structures as a whole.” Representation of a “properly unrepresentable totality” is both paradoxical and, necessarily, speculative. Yet it seems compatible with the traditional goals of realist, historical, and science fiction novels. However, in The Ministry for the Future (2020) Robinson attempts “cognitive mapping” at a scale commensurate with the unfolding of global climate change. As a result, the novel’s wide-ranging discursive content often spills over the boundaries of its genre and poses a challenge to readers, as its author explores rarefied subjects like monetary theory and climate change science and employs nonhuman narrators like photons, carbon atoms, and the concept of blockchained cyber currencies.
