I think it's true that, as is often observed, the writer is always an outsider. A writer is someone who is telling stories about what's going on, which is something you can't do if you're totally caught up in the moment.

When a novelist manages to describe or evoke something you thought or felt, without realizing that other people also found themselves in the same situation and had the same feelings, it creates that same solidarity. Maybe it's better to think of humor not as a tool to express the solidarity, but a kind of by-product. Maybe the realization "I'm not on my own on this one" is always, or often, funny.

I think humor is a really important way of creating solidarity - like, through humor you can make people realize that certain situations, where they thought they were alone, are actually shared by everyone.

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?

One of my favorite literary theorists, Mikhail Bakhtin, wrote that the defining characteristic of the novel is its unprecedented level of "heteroglossia" - the way it brings together so many different registers of language. He doesn't mean national languages, but rather the sublanguages we all navigate between every day: high language, low language, everything. I think there's something really powerful about the idea of the novel as a space that can bring all these languages together - not just aggregate them, like the Internet is so good at doing, but bring them into a dialogue.

When you're reading a novel, I think the reason you care about how any given plot turns out is that you take it as a data point in the big story of how the world works. Does such-and-such a kind of guy get the girl in the end? Does adultery ever bring happiness? How do winners become winners?

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.
