Science fiction is the very literature of change.

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

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

You can't trust reason. We threw it out of the ad profession long ago and have never missed 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.

Advertising reaches out to touch the fantasy part of people's lives. And you know, most people's fantasies are pretty sad.

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