Tim Kreider explains why science fiction tends be our most politically engaged genre of literature:
Science fiction is an inherently political genre, in that any future or alternate history it imagines is a wish about How Things Should Be (even if it’s reflected darkly in a warning about how they might turn out). And How Things Should Be is the central question and struggle of politics. It is also, I’d argue, an inherently liberal genre (its many conservative practitioners notwithstanding), in that it sees the status quo as contingent, a historical accident, whereas conservatism holds it to be inevitable, natural, and therefore just. The meta-premise of all science fiction is that nothing can be taken for granted. That it’s still anybody’s ballgame.
The contemporary example Kreider holds aloft to make his point? Kim Stanley Robinson, especially his trilogy of “Mars” novels – Red Mars, Green Mars, and Blue Mars. Kreider writes that “what’s most powerful about the Mars books as political novels is that they envision a credible utopia”:
The first wave of his Martian settlers are all scientists, who are no more perfect than any other human beings but have been rigorously trained in a kind of intellectual integrity. Robinson argues that, now that climate change has become a matter of life and death for the species, it’s time for scientists to abandon their scrupulous neutrality and enter into the messy arena of politics. Essentially, Robinson attempts to apply scientific thinking to politics, approaching it less like pure physics, in which one infallible equation-ideology explains and answers everything, than like engineering—a process of what F.D.R. once called “bold, persistent experimentation,” finding out what works and combining successful elements to synthesize something new. He scavenges ideas from the American Constitution, the Swiss confederacy, “the guild socialism of Great Britain, Yugoslavian worker management, Mondragon ownership, Kerala land tenure, and so on” to construct his utopias. … In his Mars novels, Robinson uses the Red Planet as a historical tabula rasa, a template for creating a saner, more sustainable, and more just human society.
