<human>:  What is the difference between modernism and postmodernism in literature?
<bot>: The main difference between modernism and postmodernism in literature is that modernism emphasizes a break with the traditional conventions of literature, literature that is more experimental and often non-linear. This experimentation often seeks to challenge the nature of reality and values of society. Postmodernliterature, on the other hand, focuses on self-reflexivity, irony, and the rejection of absolute truths. It often engages with themes such as fragmentation, dualism, parody, and the breakdown of narrative structure. Both movements focus on the breakdown of certain accepted conventions, but each approach it in different ways.
