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.

German can take a lot more pathos than English can. When you say "pathetic" in English it's a disparaging term, but when you say "pathetisch" in German it's just a description, not necessarily negative. That says a lot already.

When I write a book I'm always questioning the project as a whole. I always feel I might have to just throw it away and forget about it, and I've done that with novels I've started and worked on for a long time. It's an option I need in order to write freely.

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.

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.

You say fate is almost indispensable to literature - I think it's completely indispensable, at least in a novel, because a novel always has a plot. Even if nothing happens, even if someone just spends a day walking around Dublin, or whatever, there's still something going on.

I wanted to write a book that would leave open many riddles and mysteries, even to me. Of course in some cases I do know the answers, but in many others I don't know and don't want to know.
