Poetry is perhaps the oldest art form. We can go back to an age-old idea of naming things, the Adamic impulse - to give something a name has always been an immensely powerful thing. To name something is to own it, to capture it. A poem is still a kind of spell, an incantation. Historically, a poem also invoked: it was a blessing, or a curse, or a charm. It had a motile power, was able to summon something into being. A poem is a special kind of speech-act. In a good poem there's the trance-like effect of language in its most concentrated, naked form.

Now that the most interesting matter of identity is not what place someone was born in, but what point in time they are from - where they sit in relation to time. Age has become much more divisive than place. With the Internet and globalization, a twenty-year-old in New York has far more cultural references in common with a twenty-year-old in Nebraska than they do with a thirty-year-old who lives next door. National identity is what they trick you with when they want your feet in their army boots or your taxes in their bailouts.

The whole process of having to put the thing into the world seems so antithetical to the act of writing. Poetry is slightly easier, because there's less money and fewer people involved. You just let a book of poems trickle out in the world, and it finds its own people. Novels are much harder, and you don't think you should have to do some of the things you're made to do.

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.

With an age difference comes a great gap in cultural references, and so on. It's not all about race and gender. It interests me that, as you get older, your younger self becomes a stranger to you. A split occurs within yourself. But maybe we're all always strangers to ourselves.

You become a writer because you like to be alone in a room with your books.

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.
