Certainly for me prose has a dilatory capacity, insofar as I don't trust my abilities in prose. I imagine I could have done the same thing in poetry, but sometimes I feel more fluent in poetry than in prose, and as a consequence perhaps I might pass too quickly by a thing that I might, in prose, have struggled merely to articulate. That struggle creates space, and it seems to me a particular kind of space into which memory flows easily. I suspect I think better in poetry, however.
