In terms of stories I would buy for a science fiction magazine, if they take place in the future, that might do it.

I don't think the scientific method and the science fictional method are really analogous. The thing about them is that neither is really practiced very much, at least not consciously. But the fact that they are methodical does relate them.

On this day I want to tell you about, which will be about a thousand years from now, there were a boy, a girl and a love story.

My first thought was always a cigarette. It still is, but I haven't cheated.

For someone to be taken seriously it was valuable to have the appearance of someone who deserved to be taken seriously.

My old English buddy, John Rackham, wrote and told me what made science fiction different from all other kinds of literature - science fiction is written according to the science fiction method.

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.
