Utopian and dystopian fiction: The utopia and its derivative, the dystopia, are genres literature that explore social and political structures.  Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers.  Dystopian (or dystopic) fiction (sometimes combined with, but distinct from apocalyptic literature) is the opposite: the portrayal of a setting that completely disagrees with the author's ethos.  Many novels combine both, often as a metaphor for the different directions humanity can take, depending on its choices, ending up with one of two possible futures.  Both utopias and dystopias are commonly found in science fiction and other speculative fiction genres, and arguably are by definition a type of speculative fiction.
