“Why do you think it is stupid to go to windows instead of to doors?”“Because you advertise what you’re trying to hide, silly. If I have a secret, I don’t put tape over my mouth and let everyone know I have a secret. I talk just as much as usual, only about something else. Didn’t you ever read any of the sayings of Salvor Hardin? He was our first Mayor, you know.”“Yes, I know.”“Well, he used to say that only a lie that wasn’t ashamed of itself could possibly succeed. He also said that nothing had to be true, but everything had to sound true. Well, when you come in through a window, it’s a lie that’s ashamed of itself and it doesn’t sound true.”“Then what would you have done?”“If I had wanted to see my father on top secret business, I would have made his acquaintance openly and seen him about all sorts of strictly legitimate things. And then when everyone knew all about you and connected you with my father as a matter of course, you could be as top secret as you wanted and nobody would ever think of questioning it.”

“Once, when a religionist denounced me in unmeasured terms, I sent him a card saying, "I am sure you believe that I will go to hell when I die, and that once there I will suffer all the pains and tortures the sadistic ingenuity of your deity can devise and that this torture will continue forever. Isn't that enough for you? Do you have to call me bad names in addition?”

“Some readers may realize that this story, first published in 1956, has been overtaken by events. In 1965, astronomers discovered that Mercury does not keep one side always to the Sun, but has a period of rotation of about fifty-four days, so that all parts of it are exposed to the sunlight at one time or another.Well, what can I do except say that I wish astronomers would get things right to begin with?And I certainly refuse to change the story to suit their whims.”

“Many years later he looked through one of my books and said, "How did you learn all this, Isaac?""From you, Pappa", I said."From me? I don't know any of this"."You didn't have to, Pappa", I said. "You valued learning and you taught me to value it. Once I learned to value it, the rest came without trouble."- Isaac Asimov (Isaak Yudovich Ozimov). It's been a good life.”

“And [Asimov]'ll sign anything, hardbacks, softbacks, other people's books, scraps of paper. Inevitably someone handed him a blank check on the occasion when I was there, and he signed that without as much as a waver to his smile — except that he signed: 'Harlan Ellison.”

“A couple of months ago I had a dream, which I remember with the utmost clarity. (I don't usually remember my dreams.) I dreamed I had died and gone to Heaven. I looked about and knew where I was-green fields, fleecy clouds, perfumed air, and the distant, ravishing sound of the heavenly choir. And there was the recording angel smiling broadly at me in greeting. I said, in wonder, "Is this Heaven?" The recording angel said, "It is." I said (and on waking and remembering, I was proud of my integrity), "But there must be a mistake. I don't belong here. I'm an atheist." "No mistake," said the recording angel. "But as an atheist how can I qualify?" The recording angel said sternly, "We decide who qualifies. Not you." "I see," I said. I looked about, pondered for a moment, then turned to the recording angel and asked, "Is there a typewriter here that I can use?" The significance of the dream was clear to me. I felt Heaven to be the act of writing, and I have been in Heaven for over half a century and I have always known this.”

“The age of the pulp magazine was the last in which youngsters, to get their primitive material, were forced to be literate.”

“I have never, in all my life, not for one moment, been tempted toward religion of any kind. The fact is that I feel no spiritual void. I have my philosophy of life, which does not include any aspect of the supernatural and which I find totally satisfying. I am, in short, a rationalist and believe only that which reason tells me is so.”

“Having reached 451 books as of now doesn't help the situation. If I were to be dying now, I would be murmuring, "Too bad! Only four hundred fifty-one." (Those would be my next-to-last words. The last ones will be: "I love you, Janet.") [They were. -Janet.]”

“Well, sir to say that when the impossible has been eliminated, whatever remains, however improbable, is the truth, is to make the assumption, usually justified, that everything that is to be considered has indeed been considered. Let us suppose we have considered ten factors. Nine are clearly impossible. Is the tenth, however improbable, therefore true? What if there were an eleventh factor, and a twelfth, & a thirteenth...”

“Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won't come in.”
