Utopian fiction is the creation of an ideal society, or utopia, as the setting for a novel. Dystopian fiction is the opposite: creation of an utterly horrible or degraded society that is generally headed to an irreversible oblivion, or dystopia. Many novels combine both, often as a metaphor for the different directions humanity can take in its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction.
