Star Trek, I thought, was a very inconsistent show, which at times sparkled with true ingenuity and pure science fiction approaches, and other times was more carnival-like, and very much more the creature of television than the creature of a legitimate literary form.

Science fiction makes the implausible possible, while science fantasy makes the impossible plausible.

Every writer is a frustrated actor who recites his lines in the hidden auditorium of his skull.

I suppose we think euphemistically that all writers write because they have something to say that is truthful and honest and pointed and important. And I suppose I subscribe to that, too. But God knows when I look back over thirty years of professional writing, I'm hard-pressed to come up with anything that's important. Some things are literate, some things are interesting, some things are classy, but very damn little is important.

I miss the comraderie of live television - the fact that you were on the set, you worked closely with the director and the cast, that I miss. But, no, I'm happy, I'm happy doing film.

Being like everybody is the same as being nobody.

There is a fifth dimension, beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition.
