It's really a trade-off: you're always having to decide whether you're going to say the more ambitious thing, and lose a little clarity - or are you going to say something really clearly, and sacrifice a little nuance? Get too obscure, and you sound like a pretentious asshole; go overboard with the clarity, and you sound like you're talking down to your audience, or like you yourself are a reductive simpleton.

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.

If you think about Don Quixote, Don Quixote is this guy who wants to live as if he was in a medieval chivalric romance, when actually he lives in sixteenth-century Spain, which is already going through secularization, industrialization, modernization. He goes out to kill a giant, and instead he collides with this huge windmill and injures himself and also damages the windmill. I think that's a metaphor for the collisions we all have over time, as our ideas of ourselves get out of synch with the historical moment.

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.

Part of flirting is that you tend to give each other a little extra slack to be obscure - to say things that are suggestive and nuanced, rather than clear and comprehensible, things you wouldn't put up with in an essay or something written by a stranger - and that can be so exciting.

I've gotten a lot of comfort from the philosophy of the Roman Stoics. For me, one of the most powerful ideas of Stoicism is that you can't pick or choose in the world what you want to happen and what you don't want to happen, and that actually if you did get to choose, the version you would come up with would be unsociable, lame, and basically less beautiful than the truth.

In a lot of ways, being a writer is a lousy job - grueling, emotionally taxing, terrible hours, no health care - so if it wasn't about love, what would be the point?
