I want to be remembered most as a writer - one who entertained readers, and, hopefully, stretched their imagination as well.

The greatest tragedy in mankind's entire history may be the hijacking of morality by religion.

When the Sun shrinks to a dull red dwarf, it will not be dying. It will just be starting to live and everything that has gone before will merely be a prelude to its real history.

The goal of the future is full unemployment, so we can play. That's why we have to destroy the present politico-economic system.

We seldom stop to think that we are still creatures of the sea, able to leave it only because, from birth to death, we wear the water-filled space suits of our skins.

Much blood has also been spilled on the carpet in attempts to distinguish between science fiction and fantasy.

Fantasy is something that COULDN'T happen - though often you only wish that it could.

I'm surprised at some technological development, and the realization that any sufficiently advanced technology is indistinguishable from magic. I think the CD-ROM is the best example of that. The idea of having a whole symphony, or opera, or novel in a little piece of plastic is pretty amazing.
