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.

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.

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

I'm always reading books, I'm always having encounters, I'm always taking trips. Whatever it is you come up with about how you got started, that's equally true for all the books you didn't start.

What passes for love is imperfect knowledge. Not knowing, initially, allows faithlessness to dress up as its opposite; casts the inarticulate as enigmatic, the selfish as forgetful, the angry as impassioned.

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.

In terms of poetry, I worry about being far from the voice of my childhood, the rhythms of Ulster speech, and the liveliness of its dialect. I know there is a vitality to New York talk, but living among people of different cultures does mean you're forced to homogenize and lose the interesting words and phrases in order to be understood.
