Final answer:
Vonnegut would likely feel that something very strange is happening to literature, considering the evolution of the relationship between literature and history, and the literary movements from modernism to postmodernism.
Step-by-step explanation:
In the context of the information provided, Vonnegut might feel that something very strange is happening to literature. The excerpts discuss the evolution and relationship of literature with history and the transitions from different literary periods—modernism to postmodernism, for instance.
Moreover, themes such as the textuality of experiences, the impact of sociopolitical factors on narrative, and the critical evaluation of literary works all point to a convergence on the broader subject of literature. Discussions of the interplay between historical context and literary analysis.
The inner life and consciousness in literary expression (as explored by James Joyce and Virginia Woolf), and the postmodernist exploration of reality versus representation (as exemplified by Don DeLillo and David Foster Wallace) all suggest that Vonnegut, though not explicitly mentioned in these provided texts, would be concerned with contemporary shifts in the understanding and creation of literary works.
