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

The big new development in my life is, when I turned 80, I decided I no longer have to do four pages a day. For me, it's like retiring.

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.

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

That's really what SF is all about, you know: the big reality that pervades the real world we live in: the reality of change. Science fiction is the very literature of change. In fact, it is the only such literature we have.

The science fiction method is dissection and reconstruction.
