Understanding the laws of nature does not mean that we are immune to their operations.

Doesn't anybody ever want to talk about anything else besides 'Star Trek?' There were 79 episodes of the series; there were 55 different writers. I was only one of them.

My approach to 'Star Trek' was, 'I know science fiction, and I know screen writing.' That was very arrogant of me, but you really need to be a little bit arrogant to think that what you have to say is good enough to justify the expense of hundreds of thousands - now millions of dollars - to make an episode of the TV show.

Tomorrow is going to be different than yesterday, it's going to be a lot different.

The fifties are a peaceful time, a quiet sleeping time between two noisy bursts of years, a blue and white time filled with sweet yellow days, music and bright smelling memories.

Who are we? And to me that's the essential question that's always been in science fiction. A lot of science fiction stories are - at their very best - evocations of that question. When we look up at the night sky and wonder, "Is there anyone else out there?" we're also asking who we are we in relation to them.

What I wish is that people would look beyond the tribbles and see I've written some other books that I really would like people to notice. There's The Man Who Folded Himself, there's The Martian Child, which is about my son and the adoption. There's The War Against The Chtorr, which is my magnum opus, my great epic story.
