When I went to Dartmouth my teacher was Sidney Cox. I'm sure that I began writing things for him that were poems and were mine. No, I didn't know it, though it wouldn't have surprised me. There wasn' t conscious planning or a definite goal. It was simply something was happening that I hoped might continue to happen.
Writing is something that happens to the writer.
And if it doesn't happen again to the reader, you might as well not have read it. In either case it's a happening. Literature is about the reader's experience of the work. It's the reader that makes the work. Some people expect that the reading experience of the work is going to be made for them.
