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.

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.

I think New York is working its way into my poems. It takes a while for a place to filter its way onto the page, but I've been reading more and more American poetry and I certainly feel it as quite a freeing force. Coming from the formally ordered tradition of poetry in Ireland, I find the expansiveness of American literature freeing in some sense.

The reason that the book exists is because there was a gap in you. You wrote the book to fulfill that gap in some way.

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 fiction, for me, is a more indirect form of self-exploration than writing verse. When I'm working on a novel I'm moving characters around and I'm thinking about plot and there's a lot of other things going on at the level of structure and story. With a poem, a single idea or line or emotion can sometimes be enough - there's often a sense, in the best poems, of capturing a single instant. Perhaps poems differ from prose in the degree of solace they can offer - by speaking so personally, so directly, about shared experience. A few lines of poetry can provide comfort.

There is such a shelter in each other.
