"A robot must obey the orders given it by human beings except where such orders would conflict with the First Law."

"A robot may not injure a human being, or, through inaction, allow a human being to come to harm."

"I don't believe in an afterlife, so I don't have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse."

"If you suspect that my interest in the Bible is going to inspire me with sudden enthusiasm for Judaism and make me a convert of mountain‐moving fervor and that I shall suddenly grow long earlocks and learn Hebrew and go about denouncing the heathen — you little know the effect of the Bible on me. Properly read, it is the most potent force for atheism ever conceived."

"I was once being interviewed by Barbara Walters [...] In between two of the segments she asked me [...] "But what would you do if the doctor gave you only six months to live?" I said, "Type faster." This was widely quoted, but the "six months" was changed to "six minutes," which bothered me. It's "six months.""

"In the course of my fight with the school, I couldn't help but notice that I became a pariah. [...] Once, however, a fellow faculty member, making sure we were unobserved, said to me, "Isaac, the faculty is proud of you for your courage in fighting the administration for academic freedom." I said, "There's no courage involved in it. Don't you know my definition of academic freedom?" "No. What's your definition of academic freedom?" I said, "Independent income.""

"Someone once asked me, "If you had your choice, Dr. Asimov, would it be women or writing?" My answer was, "Well, I can write for twelve hours at a time without getting tired.""

"Ideas are cheap. It's only what you do with them that counts."

"The job of science will never be done, it will just sink deeper and deeper into never-ending complexity."

"It's my belief that the Universe possesses, in its essence, fractal properties of a very complex sort and that the pursuit of science shares those properties. It follows that any part of the Universe that remains un-understood, and any part of scientific investigation that remains unresolved, however small that might be in comparison to what is understood and resolved, contains within it all the complexity of the original. Therefore, we'll never finish. No matter how far we go, the road ahead will be as long as it was at the start, and that's the secret of the Universe."

"Scientific theories can always be improved and are improved. That is one of the glories of science. It is the authoritarian view of the Universe that is frozen in stone and cannot be changed, so that once it is wrong, it is wrong forever."

"If anyone can be considered the greatest writer who ever lived, it is Shakespeare."

"The foundation of all technology is fire."

"Books ... hold within them the gathered wisdom of humanity, the collected knowledge of the world's thinkers, the amusement and excitement built up by the imaginations of brilliant people. Books contain humor, beauty, wit, emotion, thought, and, indeed, all of life. Life without books is empty."

"Radiation, unlike smoking, drinking, and overeating, gives no pleasure, so the possible victims object."

"[Writing] is an addiction more powerful than alcohol, than nicotine, than crack. I could not conceive of not writing."

"I made up my mind long ago to follow one cardinal rule in all my writing — to be clear. I have given up all thought of writing poetically or symbolically or experimentally, or in any of the other modes that might (if I were good enough) get me a Pulitzer prize. I would write merely clearly and in this way establish a warm relationship between myself and my readers, and the professional critics — Well, they can do whatever they wish."

"We are meant to know, or we are amoebae. Suppose that we are wise enough to learn and know — and yet not wise enough to control our learning and knowledge, so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance. It is better to know — even if the knowledge endured only for the moment that comes before destruction — than to gain eternal life at the price of a dull and swinish lack of comprehension of a universe that swirls unseen before us in all its wonder. That was the choice of Achilles, and it is mine, too."

"All mankind, right down to those you most despise, are your neighbors."

"As indicated by our very name, we humanists celebrate humanity, want humanity to survive, and recognize that if humanity does survive, it will be by its own efforts. Never can we sit back and wait for miracles to save us. Miracles don't happen. Sweat happens. Effort happens. Thought happens. And it is up to us humanists to help — to expend our sweat, our effort and our thought. Then there will be hope for the world."

"The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom."

"The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it."

"Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it."

"[In response to this question by Bill Moyers: What do you see happening to the idea of dignity to human species if this population growth continues at its present rate?] "It's going to destroy it all. I use what I call my bathroom metaphor. If two people live in an apartment, and there are two bathrooms, then both have what I call freedom of the bathroom, go to the bathroom any time you want, and stay as long as you want to for whatever you need. And this to my way is ideal. And everyone believes in the freedom of the bathroom. It should be right there in the Constitution. But if you have 20 people in the apartment and two bathrooms, no matter how much every person believes in freedom of the bathroom, there is no such thing. You have to set up, you have to set up times for each person, you have to bang at the door, aren't you through yet, and so on. And in the same way, democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people onto the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies."

"Of all the cultural aspects of humanity, the only one which is not broken up into national or regional splinters is science. Different nations have different languages, they may have different religions, may have different dietaries, may have different holidays, different ways of thinking, but here’s only one science."

"Good literature, all if it, is supposed to illuminate the human condition."

"I suppose he's entitled to his opinion, but I don't suppose it very hard."

"All life is nucleic acid; the rest is commentary"

"The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!', but 'That's funny ...'"

"There are limits beyond which your folly will not carry you. I am glad of that. In fact, I am relieved."

"There is more to a science fiction story than the science it contains. There is also the story."

"Science fiction offers its writers chances of embarrassment that no other form of fiction does."

"In my fiction I am careful to make everything probable and to tie up all loose ends. Real life is not hampered by such considerations."

"Once you've dissected a joke, you're about where you are when you've dissected a frog. It's dead."

"Titles are an important part of a story and I take considerable care in choosing one. In fact, I cannot start a story until I have chosen a title."

"Miniaturization doesn't actually make sense unless you miniaturize the very atoms of which matter is composed. Otherwise a tiny brain in a man the size of an insect, composed of normal atoms, is composed of too few atoms for the miniaturized man to be any more intelligent than the ant. Also, miniaturizing atoms is impossible according to the rules of quantum mechanics."

"Consider the most famous pure dystopian tale of modern times, 1984, by George Orwell (1903-1950), published in 1948 (the same year in which Walden Two was published). I consider it an abominably poor book. It made a big hit (in my opinion) only because it rode the tidal wave of cold war sentiment in the United States."

"I get a certain pleasure in knowing that I live not merely in a city but in Manhattan, the center of New York City, a region so unique in many ways that I honestly believe that Earth is divided into halves: Manhattan and non-Manhattan."

"Are there things about the universe that we cannot know in the usual way of observing and measuring, but that we can know in some other way—intuition, revelation, mad insight? If so, how can you know that what you know in these non-knowing ways is really so. Anything you know without knowing, others can know only on your flat statement without any proof other than “I know!”"

"It is a rather sad commentary on humanity that it is always so attractive to think that some small group “controls the Earth”—the Jews, the international bankers, the Communists, the Masons, the Trilateral Commission. Those who believe such things are so sincere, so harried, so paranoid and, if the times are bad enough, and if the hunger for a scapegoat is great enough—so convincing. The Nazis are the most dreadful example in recent history of how far madmen can go when riding the skeletal horse of paranoia, but their example has by no means cured the world."

"There were many more stories in the course of the year that were printed and that dealt with the nuclear nightmare, and who knows how many stories that were written and were never published. It was an overriding terror in the years that immediately followed Hiroshima; and it is only the callousness of habituation that hasn’t caused the terror to increase steadily—for the danger has."

"[S]cientists have pushed back the horizon of time from the biblical 6,000 years to 4,600,000,000 years for the age of Earth—a 760,000-fold increase."

"An optimistic view of the future would indicate that before long, the clear necessity of expanding humanity's horizons would cause ... space settlements to be built. The construction would also serve as a great project that not only would be clearly of great benefit, but might induce human cooperation in something large enough to fire the heart and mind, and make people forget the petty quarrels that have engaged them for thousands of years in wars over insignificant scraps of earthly territory."

"Earth is a ball that is over 12,000 kilometres in diameter, and if it were modelled into an object the size of a billiard ball, with all its surface unevenness reproduced exactly to scale, the model would be smoother than an ordinary billiard ball—and the ocean would be an all but unnoticeable mist of dampness over 70 percent of its surface."

"I am an atheist, out and out. It took me a long time to say it. I've been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn't have. Somehow, it was better to say one was a humanist or an agnostic. I finally decided that I'm a creature of emotion as well as of reason. Emotionally, I am an atheist. I don't have the evidence to prove that God doesn't exist, but I so strongly suspect he doesn't that I don't want to waste my time."

"But suppose we were to teach creationism. What would be the content of the teaching? Merely that a creator formed the universe and all species of life ready-made? Nothing more? No details?"

"To be sure, the Bible contains the direct words of God. How do we know? The Moral Majority says so. How do they know? They say they know and to doubt it makes you an agent of the Devil or, worse, a Lbr-l Dm-cr-t. And what does the Bible textbook say? Well, among other things it says the earth was created in 4004 BC. (Not actually, but a Moral Majority type figured that out three and a half centuries ago, and his word is also accepted as inspired.) The sun was created three days later. The first male was molded out of dirt, and the first female was molded, some time later, out of his rib. As far as the end of the universe is concerned, the Book of Revelation (6:13-14) says: "And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind." ... Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes in order to tell us what books to read and what not, what thoughts to think and what not, what conclusions to accept and what not. And what does the Bible say? "If the blind lead the blind, both shall fall into the ditch" (Matthew 15:14)."

"If one thing goes without saying, almost anything can."

"The Bible and science agree in being unable to say anything certainly about what happened before the beginning. There is this difference. The Bible will never be able to tell us. It has reached its final form, and it simply doesn't say. Science, on the other hand, is still developing, and the time may come when it can answer questions that, at present, it cannot."

"There is no version of primeval history, preceding the discoveries of modern science, that is as rational and as inspiring as that of the first eleven chapters of the Book of Genesis."
