I'm not much interested in extrapolating science and technology; I merely use extrapolation as a means of putting people into new quandaries which produce colorful pressures and conflicts.

This was a Golden Age, a time of high adventure, rich living and hard dying... but nobody thought so. This was a future of fortune and theft, pillage and rapine, culture and vice... but nobody admitted it. This was an age of extremes, a fascinating century of freaks... but nobody loved it.

One of the things that everybody knows about space travel but never mentions is its aphrodisiac quality.

Don't ask the world to stop moving because you have doubts.

The appeal of science fiction has always been its iconoclasm . . . But in order to be an iconoclast, an author must be more than merely aware of the idol he wishes to destroy. He must be intimate with it and understand it in all its aspects. This means that he must have devoted serious thought to it, and have beliefs of his own which will stand up in the place of the broken idol. In other words, any child can complain, but it takes an adult to clash with accepted beliefs . . . an adult with ideas.

Millions for nonsense, but not one cent for entropy.
