We think in terms of fate even if we don't believe in it. Even something as trivial as missing the bus - we think: Well, it might be good for something. We always have that thought, no matter how critical we try to be. The idea that everything is always total chance - we're not made for that.

It's also one of these strange points where metaphysics converges with economy. Because really what the experts are doing is creating value by banishing doubt. All great dead painters basically have this one person, this expert who has the metaphysical power to grant a seal of authenticity.

One of the points where the art world is at its most metaphysical is in this weird aspect of the power of the expert. There are experts who claim they cannot be fooled because they have an inner connection to an artist and can feel whether something is genuine or fake. I've heard experts say, on panels: When it comes to my period, or my painters, I cannot be fooled. And of course that's completely ridiculous.

Exactly as we might ask God, and do ask God, to change our fate. The difference is that in the story the writer actually replies and in the end even changes his mind.

Usually the German translators do something terrible, especially with Tom Wolfe, which is that they make it local. So if the characters are from Harlem, the translators put all this Berlin slang into their mouths, and that's just terrible. You cringe when you read that. But there really is no good solution to the problem, except learning English.

Usually I work out the plot before I start. This time I thought: Writers always talk about not knowing where a book is going - -I want to experience that, too. What I found out is that it's very interesting, but it takes much longer because you have so many false starts. You take wrong turns and you have to go back and start the whole chapter, or the whole section, from scratch.

I really just wanted to write about three brothers. When you do that, though, it gives you this wonderful opportunity to tie together different social milieus, because siblings usually move into different worlds as they grow up.
