"I really can’t claim to being a science-fiction man either. Fantasy was really more my bag. And I’m very much a Johnny-Come-Lately into that. The guys – the really key men – like Asimov, Clarke, Bradbury – they all preceded me by years and years and have a body of literature to show for it. I have nothing but a television show. My only claim is that I put science-fiction and fantasy into a mass media more than any other person."

“There is an answer to the doctor's question. All the Dachaus must remain standing. The Dachaus, the Belsens, the Buchenwald, the Auschwitzes – all of them. They must remain standing because they are a monument to a moment in time when some men decided to turn the Earth into a graveyard. Into it they shoveled all of their reason, their logic, their knowledge, but worst of all, their conscience. And the moment we forget this, the moment we cease to be haunted by its remembrance, then we become the gravediggers. Something to dwell on and to remember, not only in the Twilight Zone but wherever men walk God's Earth.”

“I wish to Christ that I had written a Stagecoach drama starring John Wayne instead.”

“I happen to think that the singular evil of our time is prejudice. It is from this evil that all other evils grow and multiply. In almost everything I've written there is a thread of this: man's seemingly palpable need to dislike someone other than himself.”

“If you need drugs to be a good writer, you're not a good writer.”

“I'm dedicating my little story to you; doubtless you will be among the very few who will ever read it. It seems war stories aren't very well received at this point. I'm told they're out-dated, untimely and as might be expected - make some unpleasant reading. And, as you have no doubt already perceived, human beings don't like to remember unpleasant things. They gird themselves with the armor of wishful thinking, protect themselves with a shield of impenetrable optimism, and, with a few exceptions, seem to accomplish their "forgetting" quite admirably. But you, my children, I don't want you to be among those who choose to forget. I want you to read my stories and a lot of others like them. I want you to fill your heads with Remarque and Tolstoy and Ernie Pyle. I want you to know what shrapnel, and "88's" and mortar shells and mustard gas mean. I want you to feel, no matter how vicariously, a semblance of the feeling of a torn limb, a burnt patch of flesh, the crippling, numbing sensation of fear, the hopeless emptiness of fatigue. All these things are complimentary to the province of war and they should be taught and demonstrated in classrooms along with the more heroic aspects of uniforms, and flags, and honor and patriotism. I have no idea what your generation will be like. In mine we were to enjoy "Peace in our time". A very well meaning gentleman waved his umbrella and shouted those very words...less than a year before the whole world went to war. But this gentleman was suffering the worldly disease of insufferable optimism. He and his fellow humans kept polishing the rose colored glasses when actually they should have taken them off. They were sacrificing reason and reality for a brief and temporal peace of mind, the same peace of mind that many of my contemporaries derive by steadfastly refraining from remembering the war that came before.”

“I got the idea for the pilot while walking through an empty lot of a movie studio. There were all the evidences of a community but with no people. I felt at the time a kind of encroaching loneliness, and desolation; a feeling of how nightmarish it would be to wind up in a city with no inhabitants.”
