First book was handwritten, then the printing press, now we've got our Kindles. To be able to push a button and a dictionary comes up. And then, at my age, that I can make the letters any size I want, and that I can carry all of William Shakespeare, all of Gogol, all of Franz Kafka in my handbag? You've got to love it.

There seems to me now to be the notion that you send something to a journal or an agent and months go by. It seems to me like that is a new piece of bad manners. Probably. Generally I assume that anything that happens now happened to Adam and Eve also.

Once you start on an idea it proliferates in itself.

There's that wonderful line in Measure for Measure. I forget which of the characters has committed adultery and is going to die. He looks at his hand and says, "How could this die?" That's the joke. I've always thought, and this is nothing new, that we don't really believe we die. I think you're going to die, because I know that's what happens but I can't imagine I'm going to die.

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.

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'm not going to say it's laziness, but I'm not a grand creator of new characters.
