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.

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.

I don't read novels that are looking to convince me of anything. I believe that literature needs to be a machine of illusions.

Identity is gradual, cumulative; because there is no need for it to manifest itself, it shows itself intermittently, the way a star hints at the pulse of its being by means of its flickering light. But at what moment in this oscillation is our true self manifested? In the darkness or the twinkle?

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.

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.

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.
