How then to enforce peace? Not by reason, certainly, nor by education. If a man could not look at the fact of peace and the fact of war and choose the former in preference to the latter, what additional argument could persuade him? What could be more eloquent as a condemnation of war than war itself? What tremendous feat of dialectic could carry with it a tenth the power of a single gutted ship with its ghastly cargo?

The newsmen were writing down sentences busily as Hoskins spoke to them. They did not understand and they were sure their readers would not, but it sounded scientific and that was what counted.

The Autarch maintained his indifferent calm, but a certain lack of certainty was gathering, and he did not like to experience a lack of certainty. He liked nothing which made him aware of limitations. An Autarch should have no limitations, and on Lingane he had none that natural law did not impose.

Without the interplay of human against human, the chief interest in life is gone; most of the intellectual values are gone; most of the reason for living is gone.

The work of each individual contributes to a totality and so becomes an undying part of the totality. That totality of human lives - past and present and to come - forms a tapestry that has been in existence now for many thousands of years and has been growing more elaborate and, on the whole, more beautiful in all that time. Even the Spacers are an offshoot of the tapestry and they, too, add to the elaborateness and beauty of the pattern. An individual life is one thread in the tapestry and what is one thread compared to the whole?

No matter how various the subject matter I write on, I was a science-fiction writer first and it is as a science-fiction writer that I want to be identified.

Writing is hard work. The fact that I love doing it doesn't make it less hard work. People who love tennis will sweat themselves to exhaustion playing it, and the love of the game doesn't stop the sweating. The casual assumption that writers are unemployed bums because they don't go to the office and don't have a boss is something every writer has to live with. I have never known a writer who hasn't suffered as a result of this, hasn't resented it, and hasn't dreamed of murdering the next person who says "Boy, you've sure got it made. You just sit there and toss off a story or something whenever you feel like it."

The fact is that I've never called myself a genius, and I think the term has been cheapened by overuse into meaninglessness. If other people want to call me that, that's their problem.

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.

The best way to describe anyone is to give an example of the kind of thing he would do.

I joke sometimes to the effect that when I approach a part of a book where I must explain something I don't understand, I just type faster and faster and faster. Then, when I get to the part I don't understand, sheer inertia pushes me through. That's not literally true, of course, but there's something to it psychologically.

People don't stop things they enjoy doing just because they reach a certain age. They don't stop playing tennis just because they turn 40, they don't stop with sex just because they turn 40; they keep it up as long as they can if they enjoy it, and learning will be the same thing.

There are many aspects of the universe that still cannot be explained satisfactorily by science; but ignorance only implies ignorance that may someday be conquered. To surrender to ignorance and call it God has always been premature, and it remains premature today.

Of all the books I have ever worked on, I think Asimov's Guide to Shakespeare gave me the most pleasure, day in, day out. For months and months I lived and thought Shakespeare, and I don't see how there can be any greater pleasure in the world, any pleasure, that is, that one can indulge in for as much as ten hours without pause, day after day indefinitely.

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.

If one thing goes without saying, almost anything can.

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. Banquets of the Black Widowers (1984), p. 49; comparable to "Humor can be dissected, as a frog can, but the thing dies in the process and the innards are discouraging to any but the pure scientific mind."

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.

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.

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.

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.

Scientists 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.

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?

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

I am not a visual person. I have spent so many bounded years in my childhood that I have grown used to having books as my window on reality.

The foundation of all technology is fire.

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."

Earth governments in moments of stress are not famous for being reasonable.

"Why didn't people just use a computer?" "That was before they had computers," cried Paul. "Before?" "Sure. Do you think people always had computers? Didn't you ever hear of cavemen?"

Printing will tell you such useful things and such interesting things that not being able to read would be as bad as not being able to see.

Modesty is an unnatural attitude, and one which is only with difficulty taught to children.

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

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.

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

The Dantean conceptions of Inferno were childish and unworthy of the Divine imagination: fire and torture. Boredom is much more subtle. The inner torture of a mind unable to escape itself in any way, condemned to fester in its own exuding mental pus for all time, is much more fitting. Oh, yes, my friend, we have been judged, and condemned, too, and this is not Heaven, but hell.

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."

He could almost wish he were superstitious. He could then console himself with the thought that the casual meaningless meeting had really been directed by a knowing and purposeful Fate.

What a human being believes, however, no matter with what ardor, is not necessarily objective truth.

If the love of money is the root of all evil, the need of money is most certainly the root of all despair.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

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.

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.

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.

We face eternity now. We have no universe left, no outside phenomena, no emotions, no passions. Nothing but ourselves and thought. We face an eternity of introspection, when all through history we have never known what to do with ourselves on a rainy Sunday.
