I don't know whether a poem has be there to help to develop something. I think it's there for itself, for what the reader finds in it.
Nothing has existence unless you, I, or some living creature perceives it, and how it is perceived further influences that reality. Even time itself is not exempted from biocentrism.
I love hard political debate and I love beating somebody on a political point but what I'm more frustrated by is the politics where you play the man not the politics.
