Did the nineteenth-century novelists create more generously than we do now? In a general reading of contemporary work, do you see a lot of new and different characters, or is it the same character who is a stand-in for the writer? And it's interesting enough, but it's a weakness I think. We are much more self-revealing and less able to produce new people over and over again.

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.

Once you start on an idea it proliferates in itself.

As soon as you move through the hospital doors you've removed yourself from real life. From the world we know. It's an alien world. Just enter those gates and you are in alien territory.

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'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.

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.
