My idea in Half the Kingdom was simply, or not so simply perhaps, that medical science has given us twenty extra years of life. Those twenty extra years - one is grateful for them, one is happy, but they also give you ten or twenty years more of losing your faculties. That is actually the origin of my notion. Once you live longer than you're supposed to live, things go dreadfully wrong. But nevertheless, you're not dead.

I imagine witches to be people who sit around like my witty grandmother, people who are injustice collectors or humiliation collectors. I choose to imagine that's what a witch is. The reason witches are so evil is because they're so unhappy and so hurt.

I'm bad at thinking about society. I love to make fun of very small aspects. For instance the privacy rules we have in the States. Where you sign this thing that you've never read, and if you ever read it you discover there's no privacy whatsoever. But I don't know how to think sociologically, to tell you the truth. My son is a political scientist and my daughter-in-law is a sociologist. I can't think that way. I am not a good political militant at all. I keep thinking about what the other side must look like.

I've often tried to describe how memory works. I've suggested this to students, and told them to close their eyes and try to remember what I look like. Then I ask them if they remember what I look like. But when you open your eyes you will be surprised how different what you thought I looked like is to what I actually look like. Because the imagination is a different raw material from actual vision. Memory is very different from the thing itself.

I read on a Kindle. I must be of the opinion that the new way to read is a pretty good way to read. It's a new way. Those of us who like the smell of books get upset but nevertheless this is the way we're going.

It's hard for us sophisticates to believe, but the people my parents worked for were good people. They were socialists of the heart. They were Scottish upper class. I don't think they had political theories in the way my lefty friends in New York do but they did all the things that socialists do. My mother was the Jewish cook from Vienna and they would say, "Come and have dinner with us." I spent weekends with them. Who does that? This is Utopia.

Gustave Flaubert said, "Emma Bovary, c'est moi." It is not possible to write something you are not, but to have a new form, with a different hair color and a new body ... I do very little of that. That's why I keep bringing up the same people. I haven't given myself a hard time about it. But I can't make six new characters instead of one.
