I don't know how poetry knows. What it knows I also cannot say, though I have heard poetry say it, so I know it in that passive sense. That it knows seems to me only a kind of tautology poorly phrased. I would rather say that poetry is one among the many forms of knowing, and maybe it is knowing in the purest form we know. I would rather say that knowing freed from the agenda of possession and control - knowing in the sense of stepping in tune with being, hearing and echoing the music and heartbeat of being - is what we mean by poetry.
