A great deal of absurdist fiction may be humorous or irrational in nature. The absurdist humor is described as a manner of comedy that relies on non-sequiturs, violation of causality, and unpredictable juxtapositions. However, the hallmark of the genre is neither comedy nor nonsense, but rather, the study of human behavior under circumstances (whether realistic or fantastical) that appear to be purposeless and philosophically absurd. Absurdist fiction posits little judgment about characters or their actions; that task is left to the reader. Also, the "moral" of the story is generally not explicit, and the themes or characters' realizations — if any — are often ambiguous in nature.
