I don't think there's any law where you have to read a poem and immediately understand it.

Poetry is a way of being alone without feeling alone. It allows you to experience another mind, I suppose. And it does that more fully than other art forms, I think. It doesn't simply describe an experience, or a feeling, or a moment: it evokes it through, say, rhythm or tone or diction or metaphor. It creates a mood. A poem communicates before it is understood; it's not a fully paraphrasable form, which distinguishes it from other forms of writing.

Publishing a book is a great thing, and I'm grateful, but it's also a horrible, exposing thing. Once you've published a book, you never write quite as freely again. You're aware, from that point onward, of the kinds of things critics might say about it. You're aware of the kinds of things your publishers might like and dislike about it. You're half-aware of marketing strategies - of all the stuff around the book. Whereas with your very first piece of fiction, if you're lucky, those things barely occur to you at all.

I think all writing is political. All writing shows a preoccupation with something, whatever that thing might be, and by putting pen to paper you are establishing a hierarchy of some sort - this emotion over that emotion, this memory over that memory, this thought over another. And isn't that process of establishing a hierarchy on the page a kind of political act?

New York is great for writers insofar as you can pay someone to bring you food, to take your washing out and bring it back clean. It enables you. Writers always feel guilty when they're doing anything but writing, and New York allows you to really write all the time if you want to - though my kids put a limit on it.

Writing a poem is a more personal experience, I think, than writing prose. And perhaps reading a poem is a more personal experience than reading prose, though that's harder to say.

It seems to me that metaphors come down to a certain idea of interconnectedness - that everything relates to everything else. Metaphors don't believe in autonomy. And in the end, perhaps that idea of interconnectedness is a moral position.
