I'm a Postmodernist at heart in that I believe that each poem lives a new life every time it is read. The author's intent is less relevant than a reader's interpretation. The context from which a text emerges is relevant more as a matter of curiosity than as a matter of arriving at some schooled and definitive interpretation. The author wasn't even fully aware of all that he or she did, anyway, because some of what emerged during the creative process was unconscious.
Without ambiguities, a poem would live a very short life, so when authors become oddly angry or surprised about certain interpretations of their works (Beckett among others), they are forgetting that without those various interpretations, their work would die and so, then, would their careers.
I am also, paradoxically, a Modernist at heart in that I value form and theme and am interested in the context from which a text is created -- but typically only after I first read the text "raw."
What are you? Remember that as a scholar you get to decide!
