Science fiction is the very literature of change.

When I sit down to the feast of life ... I'm so busy planning on how to pick up the check, and wondering what the other people think of me for paying it, and wondering if I have enough money in my pocket to pay the bill, that I don't get around to eating.

I was thinking of writing a little foreword saying that history is, after all, based on people's recollections, which change with time.

Advertising reaches out to touch the fantasy part of people's lives. And you know, most people's fantasies are pretty sad.

People as me how I do research for my science fiction. The answer is, I never do any research.

I'm pretty catholic about what constitutes science fiction.

It's clear that science and science fiction have overlapping populations.
