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.

The science fiction method is dissection and reconstruction.

A good science fiction story should be able to predict not the automobile but the traffic jam.

You can't really predict the future. All you can do is invent it.

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

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

What were we doing here? Traveling hundreds or thousands of light-years, to break our hearts?

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.

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

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.

I'm doing a book, 'Chasing Science,' about the pleasures of science as a spectator sport.

God is the Maker of heaven and earth.

I think happiness is love.

If I make a movie in English, the money will come from Europe, so that I can keep my independence and freedom. The way they produce in Hollywood doesn't fit me.

The establishment is made up of little men, very frightened.

However smothered under former negligence, or scattered through the dull, dark mass of common thoughts - let thy genius rise as the sun from chaos.

If there wasn't a God we would have to invent one to keep people sane.

We can afford almost any mistake once.

Hormones are nature's three bottles of beer.

That's something that I just can't underestimate the importance of, the staff continuity. I really think that the players feed off the coaches.

Finally the world would see my full range of comedy characters - from grouchy librarian to Russian librarian.
