I wanted to write about the time when science became modern, around the 1950s. Right after physicist J. Robert Oppenheimer, science started being so politicized and used as such a political weapon. When my father, who is a scientist, tells me about those years, I get a competing portrait of people who were expected to behave normally and be decent respectable members of society and who were also allowed this freedom to think in big and expansive ways. Now, when you think about people who work in labs, they're allowed to be socially inept in a very fundamental way.

When you're 21 you think, "Old people sound like this. Old people think like this." I don't think my ideas about aging and about eternal life changed that much, but it became more poignant to me as I did get older and I could better imagine, as you sort of inch closer to death every day, why legacy, more than aging, becomes important to people.

We're living in a literary age, at least in America, that is marked by a sense of distance, a coolness, in all senses of that word. To be too obviously, unapologetically emotional is to risk being considered foolish, or at the very least not serious.

I was fortunate to be at that school in an era in which encounters between students and teachers were encouraged; there were a number of teachers who lived on campus, and they'd regularly invite students over for dinner on the weekends. I hope it's still like that: being treated seriously by an adult you admire is a great gift. Children, like adults, want respect - but it's only when you're older that you realize how few people actually extend it.

Sometimes the most difficult thing you can do as an editor is not make a single note - the idea that everything and everyone needs editing is, in reality, a fiction. I've gotten pieces where I thought, Well, I could do this or that, or change this word, but in the end, I leave it. Changing something is not necessarily equivalent to making the piece more true to itself, which is the point of editing: it's just changing it because you feel you can or should or must.

I've never really understood the desire to be immortal myself. The idea of both wanting to live forever in some form and wanting to stay young forever just sounds exhausting. It's one of those desires that people think they want but when you actually stop to think about what it actually means, it's really awful. One of the reasons that life is bearable is because it's going to end soon. One of the main concerns of fiction is how do we make a life of 85 years or so meaningful.

I have one friend to whom I've told more than I've ever told anyone, and yet there are significant territories I have and will never let him access - in large part because I'm trying to protect him, and one of the responsibilities of loving someone is protecting him or her, even if who you're protecting them from is yourself.
