I can say with a solid degree of authority that I am a selfish person. I spontaneously forget the names of more people than not, unless I want to make out with them. I will take the last square of toilet paper off the roll without thinking twice. I tip taxi drivers so poorly I'm amazed none of them have run over my foot while speeding off.

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.
