Haruki Murakami

Every day I go to my study and sit at my desk and put the computer on. At that moment, I have to open the door. It's a big, heavy door. You have to go into the Other Room. Metaphorically, of course. And you have to come back to this side of the room. And you have to shut the door.

In 'The Plato Papers' I wanted to get another perspective on the present moment by extrapolating into the distant future. So in that sense, there's a definite similarity of purpose between a book set in the future and a book set in the past.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
