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

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.

The science fiction method is dissection and reconstruction.

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.

You don't think progress goes in a straight line, do you? Do you recognize that it is an ascending, accelerating, maybe even exponential curve? It takes hell's own time to get started, but when it goes it goes like a bomb.

They were two lovely choices. One of them meant giving up every chance of a decent life forever...and the other one scared me out of my mind.
