The science fiction method is dissection and reconstruction.

I did that for 40 years or more. I never had any writer's block. I got up in the morning, sat down at the typewriter - now, computer - lit up a cigarette.

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

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

That's what life is, just one learning experience after another, and when you're through with all the learning experiences you graduate and what you get for a diploma is, you die.

Science fiction is the very literature of change.

I'm pretty catholic about what constitutes science fiction.
