I tend to see literary approaches as at least potentially postmodern
insofar as they bring into the foreground the the means by which
knowledge and understanding are constructed and communicated.

 Thanks, Andrew. That clarifies what you meant for me.

However, I think I’d want to argue that postmodern literary approaches go  further than what you are suggesting, for better or worse. There is, after all, quite a spectrum from socio-historical, literary-grammatical and reader-response approaches.

I think that’s only worth pointing out because I think there’s a risk of openness being seen as the postmodern theology, which is no less naive than those who think that adding doughnuts and sofa’s to their services will make them ‘emerging’ and therefore a guaranteed route to success.
