“Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.”

“Science fiction is the most important literature in the history of the world, because it's the history of ideas, the history of our civilization birthing itself. ...Science fiction is central to everything we've ever done, and people who make fun of science fiction writers don't know what they're talking about.”

“Science fiction is the art of the possible not the impossible.”

“Anything you dream is fiction, and anything you accomplish is science, the whole history of mankind is nothing but science fiction. ”

“The minute you get a religion you stop thinking. Believe in one thing too much and you have no room for new ideas.”

“My stories run up and bite me on the leg—I respond by writing down everything that goes on during the bite. When I finish the idea lets go and runs off.”

“If you want to write, if you want to create, you must be the most sublime fool that God ever turned out and sent rambling. You must write every single day of your life. You must read dreadful dumb books and glorious books, and let them wrestle in beautiful fights inside your head, vulgar one moment, brilliant the next. You must lurk in libraries and climb the stacks like ladders to sniff books like perfumes and wear books like hats upon your crazy heads. I wish you a wrestling match with your Creative Muse that will last a lifetime. I wish craziness and foolishness and madness upon you. May you live with hysteria, and out of it make fine stories — science fiction or otherwise. Which finally means, may you be in love every day for the next 20,000 days. And out of that love, remake a world.”
