Eventually scientists will discover something that explains ghosts, just like they discovered electricity, which explained lightning, and it might be something about people's brains, or something about the earth's magnetic field, or it might be some new force altogether. And then ghosts won't be mysteries. They will be like electricity and rainbows and nonstick frying pans.

I was born too late for steam trains and a lazy eye meant I'd never be an astronaut.

I read very, very little fiction as a kid. All the books I can remember are junior science books.

As to the number of novels I've abandoned... I shudder to think. I have thrown away five completed novels, and that's a gruesome enough figure. But not necessarily a waste of effort.

Siobhan said that when you are writing a book you have to include some descriptions of things. I said that I could take photographs and put them in the book. But she said the idea of a book was to describe things using words so that people could read them and make a picture in their own head.

What I love about the theatre is that it's always metaphorical. It's like going back to being a kid again, and we're all pretending in a room. Sometimes, when the pretending really works, I find it much, much more moving than something on film.

One person looks around and sees a universe created by a god who watches over its long unfurling, marking the fall of sparrows and listening to the prayers of his finest creation. Another person believes that life, in all its baroque complexity, is a chemical aberration that will briefly decorate the surface of a ball of rock spinning somewhere among a billion galaxies. And the two of them could talk for hours and find no great difference between one another, for neither set of beliefs make us kinder or wiser.
