• outside intelligences, exploring the Solar System with true impartiality, would be quite likely to enter the Sun in their records thus: Star X, spectral class G0, 4 planets plus debris.

• What I will be remembered for are the Foundation Trilogy and the Three Laws of Robotics. What I want to be remembered for is no one book, or no dozen books. Any single thing I have written can be paralleled or even surpassed by something someone else has done. However, my total corpus for quantity, quality and variety can be duplicated by no one else. That is what I want to be remembered for.

• People are entirely too disbelieving of coincidence. They are far too ready to dismiss it and to build arcane structures of extremely rickety substance in order to avoid it. I, on the other hand, see coincidence everywhere as an inevitable consequence of the laws of probability, according to which having no unusual coincidence is far more unusual than any coincidence could possibly be.

• Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today — but the core of science fiction, its essence, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.
  • "My Own View" in The Encyclopedia of Science Fiction (1978) edited by Robert Holdstock; later published in Asimov on Science Fiction (1981).

• It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be ... This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.

• 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.
  • Free Inquiry (Spring 1982)

• 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 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."
  • Asimov Laughs Again (1992)

• 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. I personally resent it bitterly.

• 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.
  • As quoted in Philosophy on the Go (2007) by Joey Green, p. 222

• [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."

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

The Foundation series

• Violence is the last refuge of the incompetent.
  • "Foundation", Astounding Science-Fiction, May 1942 (this appears three times in "Bridle and Saddle" which is titled "The Mayors" within Foundation). It is derived from the famous phrase by Samuel Johnson: "Patriotism is the last refuge of a scoundrel."

• It pays to be obvious, especially if you have a reputation for subtlety.

• For it is the chief characteristic of the religion of science that it works, and that such curses as that of Aporat's are really deadly.

• A fire eater must eat fire even if he has to kindle it himself.
  • "Bridle and Saddle", Astounding Science-Fiction, June 1942

• Never let your sense of morals prevent you from doing what is right.

• There's something about a pious man such as he. He will cheerfully cut your throat if it suits him, but he will hesitate to endanger the welfare of your immaterial and problematical soul.
  • "The Big and the Little", Astounding Science-Fiction, August 1944

• Korell is that frequent phenomenon in history: the republic whose ruler has every attribute of the absolute monarch but the name. It therefore enjoyed the usual despotism unrestrained even by those two moderating influences in the legitimate monarchies: regal 'honor' and court etiquette.

• Now any dogma, based primarily on faith and emotionalism, is a dangerous weapon to use on others, since it is almost impossible to guarantee that the weapon will never be turned on the user.

• An atom-blaster is a good weapon, but it can point both ways.

• It's a poor blaster that doesn't point both ways.

Three Laws of Robotics

• A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
  • "Runaround" in Astounding Science Fiction (March 1942); later published in I, Robot (1950). This statement is known as "The First Law of Robotics"

• A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
  • "Runaround" in Astounding Science Fiction (March 1942); later published in I, Robot (1950). This statement is known as "The Second Law of Robotics"

• A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
  • "Runaround" in Astounding Science Fiction (March 1942); later published in I, Robot (1950). This statement is known as "The Third Law of Robotics"

• A robot may not injure humanity, or, through inaction, allow humanity to come to harm.
  • Robots and Empire (1985) This statement is known as "The Zeroth Law of Robotics"; a variant of it first occurred in The Evitable Conflict (1950) as: "No robot may harm humanity, or through inaction, allow humanity to come to harm."

The Roving Mind (1983)

• Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?
  No, I reply. No, no, no, no, and again no.
  One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"
  "Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be."

• Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and scorn and ignore other fields, they grow less wise — even in their own field.
  • Ch. 25

• How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.
