Absurdist fiction is a genre of fictional narrative (traditionally, literary fiction), most often in the form of a novel, play, poem, or film, that focuses on the experiences of characters in situations where they cannot find any inherent purpose in life, most often represented by ultimately meaningless actions and events that call into question the certainty of existential concepts such as truth or value. Common elements in absurdist fiction include satire, dark humour, incongruity, the abasement of reason, and controversy regarding the philosophical condition of being "nothing." Works of absurdist fiction often explore agnostic or nihilistic topics.
