Like when you pick up a book and you don't realize what type of text it is - it could be an essay, a novel, a biography - and at one point you realize you don't know where, as a reader, you want to be. Where are you going with this text? What is the goal? How are you supposed to interpret what you're reading? And people's responses vary - some dislike it, and are put off by the confusion, the lack of comprehension.

The walk is like a matrix, like a diffuse, vague happening. It's like - imagine a play, a work of theatre, that is totally vague, almost devoid of details that consists in one person going on a walk. And as a consequence, there is a necessary tension between the determinacy and indeterminacy, the definite and the indefinite, of possibility.

For me, it's a way to find a fiction within a fiction. To find a way to uncover that blunder within the "lie," because when you look closer, every "lie" - and I say that with quotation marks - can be much more complicated. Because that is what fiction is: it's probably the least important thing in the world. It's rich, but it is put-on, it passes the time. It borrows from the world, but it does not invent it.

A word, and all the infinite fluctuations it may possess. Like that moment when you know you have something to say, and you know you're speaking, even, but you still have no idea how you will say it. Or the moment when, as a reader, you're reading, and you are understanding what you are reading, but still have utterly no idea what will come next for you, what precisely the author wants to say. For me, that is the ultimate level of literary depth, of literary density.

Not to say that the process assumes anything of "greater" or "lesser" importance, though: it's just more graphic information. Take the surrealists, for example, or a work by Cage. For me, there's a great value in doing this with literature. There's a certain form of dependence; process and product inform each other, depend on each other. I consider myself a writer who doesn't write with a style, almost. I begin with tension, with a vibe, a character.

What I find is that many times when I work with chance, with indeterminacy, I am more open to experience, less prone to a fixed process, and I think it creates a very important challenge. It creates a way of writing that is, in a way, flatter or smooth, a surface conducive to release, to movement. And in this way, the form of writing gets delightfully melded with the process of the writing.

For me parks are good when first of all, they're not impeccable, and when solitude has appropriated them in such a way that solitude itself becomes an emblem, a defining trait for walkers, sporadic at best, who in my opinion should be irrevocably lost or absorbed in thought, and a bit confused, too, as when one walks through a space that's at once alien and familiar.
