User: What is the definition of postmodernism?
Assistant: Postmodernism is an overarching term that describes the broad cultural, philosophical, aesthetic, and intellectual movements that have emerged since the mid-20th century and have emerged in part as a reaction to modernism. It is associated with ideas of relativism, construction, sifting, and fragmentation, and is critical of the traditional belief in absolute truth or universal values. Postmodernism is characterized by an openness to different interpretations and is often seen as an expression of a feeling of being overwhelmed by the complex nature of modernity.
