They said God was on high and he controlled the world and therefore we must pray against Satan. Well, if God controls the world, he controls Satan. For me, religion was full of misstatements and reaches of logic that I just couldn't agree with.

Star Trek speaks to some basic human needs: that there is a tomorrow — it's not all going to be over with a big flash and a bomb; that the human race is improving; that we have things to be proud of as humans. No, ancient astronauts did not build the pyramids — human beings built them, because they're clever and they work hard. And Star Trek is about those things.

The network told me to get rid of Number One, the woman first lieutenant, and also get rid of 'that Martian fellow'... meaning, of course, Spock. I knew I couldn't keep both, so I gave the stoicism of the female officer to Spock, and married the actress who played Number One. Thank God it wasn't the other way around. I mean Leonard's cute, but...

For me science fiction is a way of thinking, a way of logic that bypasses a lot of nonsense. It allows people to look directly at important subjects.

They say that ninety per cent of TV is junk. But ninety per cent of everything is junk.

I have always been reasonably leery of religion because there are so many edicts in religion, 'thou shalt not,' or 'thou shalt.' I wanted my world of the future to be clear of that.

Let me end with an explanation of why I believe the move into space to be a human imperative. It seems to me obvious in too many ways to need listing that we cannot much longer depend upon our planet's relatively fragile ecosystem to handle the realities of the human tomorrow. Unless we turn human growth and energy toward the challenges and promises of space, our only other choice may be the awful risk, currently demonstrable, of stumbling into a cycle of fratricide and regression which could end all chances of our evolving further or of even surviving.
