I believe that all poetry is formal in that it exists within limits, limits that are either inherited by tradition or limits that language itself imposes.
I certainly can't speak for all cultures or all societies, but it's clear that in America, poetry serves a very marginal purpose. It's not part of the cultural mainstream.
I think the best American poetry is the poetry that utilizes the resources of poetry rather than exploits the defects or triumphs of the poet's personality.
If poetry should address itself to the same needs and aspirations, the same hopes and fears, to which the Bible addresses itself, it might rival it in distribution.
Most people read poetry listening for echoes because the echoes are familiar to them. They wade through it the way a boy wades through water, feeling with his toes for the bottom: The echoes are the bottom.
