If you're writing a book where you want to make a positive truth claim, then you should absolutely call it nonfiction or memoir. If you don't want to make that claim - if that's not what's important to you; if you're more interested in storytelling and interiority and interpersonal relationships than in objective, checkable facts about the world - then why wouldn't you call it a novel, and take advantage of what that gets you, of the extra freedom, of belonging to the tradition of the novel?
I think any start has to be a false start because really there’s no way to start. You just have to force yourself to sit down and turn off the quality censor. And you have to keep the censor off, or you start second-guessing every other sentence. Sometimes the suspicion of a possible false start comes through, and you have to suppress it to keep writing. But it gets more persistent. And the moment you know it’s really a false start is when you start … it’s hard to put into words.
When you invent something, you're drawing on reservoirs of knowledge that you already have. It's only when you're faithful to the truth that something can come to you from the outside.
I thought clarity of communication was the most important thing in writing, and if you really cared about getting your idea across, you would say it in the most straightforward way possible. Later, in college and grad school, I came to realize that language is a technology like any other, and that it's always evolving - clarity of expression is always evolving.
I've been thinking a lot about why it was so important to me to do The Idiot as a novel, and not a memoir. One reason is the great love of novels that I keep droning on about. I've always loved reading novels. I've wanted to write novels since I was little. I started my first novel when I was seven.I don't have the same connection to memoir or nonfiction or essays. Writing nonfiction makes me feel a little bit as if I'm producing a product I don't consume - it's a really alienating feeling.
In the last volume of In Search of Lost Time, Proust compares himself to Scheherazade: he says he has finally understood the nature of the book he has to write, just at the moment when his advancing years and declining health have made him doubt that he's going to live long enough to write it. So he has to write against death like Scheherazade.
In a way all writers are writing against death, because writing is an attempt to defy the passage of time, to refuse to let the past disappear and be forgotten, and to refuse to let the present become the past - to try to keep living another day, to try to talk your way into life, or seduce your way into it.
