I’m currently re-reading through Tom Wright’s New Testament and the People of God especially the sections about critical realism and literature. Just to show that Wright was not out on a limb on this one, I found this great critique by José López and Garry Potter about postmodernity, “The alleged loss of hegemonic meanings in the social world were not so much explained but reproduced in texts through all type of narrative and rhetorical strategies. This led to a type of writing, and argumentation, which was rich and seductive, dense almost mystical. A type of writing that celebrated ambiguity, and enthroned irony. A type of writing that, at its worst, demanded little in terms of evidence, and argumentative coherence and consistency, the playfulness of language took precedence.”
