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.

When I use a name or place, I want to leave the reader open to the waterfall of determinacy that it may provoke. And I don't know, but I must mention the name Borges. I try to mention it in every one of my works. It's a mark, a stamp, a sort of homage to Argentinidad. But it's an homage that works through pat phrases, those stock images that populate his work: the night, labyrinths, libraries. That is, I don't want simply to pay homage to Borges, but rather the contrary: to recall his commonplaces.

I find that, for me, it is this concept of borrowed or built life, life on loan, that gets me writing. It's similar to speaking about literature. I like it, and then I don't like it. It has such an inherent vein of pretention, because you're not speaking about real things. There's a literary pretentiousness made of speaking and spending so much time on unreal persons. And it seems, now, impossible to create an unpretentious, totally organic character.

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 a long time, we assume we know who we are, until the moment we fully realize who that is; in that moment, identity is no longer predictable, but rather takes the form of a truth that, like any other, can become a sentence with no more than a change of perspective.

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.

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?
