Isaac Asimov Quotes

Violence is the last refuge of the incompetent.

Past glories are poor feeding.

It is not so much that I have confidence in scientists being right, but that I have so much in nonscientists being wrong.

Fifty years," I hackneyed, "is a long time.""Not when you're looking back at them," she said. "You wonder how they vanished so quickly.

The clown’s eyes sidled towards her, then drew away quickly. “But they kept me away from you earlier-and, on my word, you may laugh, but I was lonely for missing friendship.

Were I to use the wits the Spirits gave me, then I would say this lady cannot exist cannot exist - for what sane man would hold dream to be reality. Yet rather would I not be sane and lend belief to charmed, enchanted eyes.

Agitation from the other side of the desk.“No—now you must take this phlegmatically. You had hoped you would qualify. You had feared you would not. Actually, both hope and fear are weaknesses. You knew you would qualify and you hesitate to admit the fact because such knowledge might stamp you as cocksure and therefore unfit. Nonsense! The most hopelessly stupid man is he who is not aware that he is wise. It is part of your qualification that you knew you would qualify.”Relaxation on the other side of the desk.“Exactly. Now you feel better and your guard is down. You are fitter to concentrate and fitter to understand. Remember, to be truly effective, it is not necessary to hold the mind under a tight, controlling barrier which to the intelligent probe is as informative as a naked mentality. Rather, one should cultivate an innocence, an awareness of self, and an unselfconsciousness of self which leaves one nothing to hide. My mind is open to you. Let this be so for both of us.

I wouldn't want [the people of Baleyworld] to live that long as a general thing. The pace of historical and intellectual advance would then become too slow. Those at the top would stay in power too long. Baleyworld would sink into conversation and decay - as your world has done.

Of course there are worlds. Millions of them! Every star you see has worlds, and most of those you don't see.

Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.

There is nothing your knife handlers can do in the way of rioting and demonstrating that will have any permanent effect as long as, in the extremity, there is an army equipped with kinetic, chemical, and neurological weapons that is willing to use them against your people. You can get all the downtrodden and even all the respectables on your side, but you must somehow win over the security forces and the Imperial army or at least seriously weaken their loyalty to the rulers.

[A]n unpleasant nest of nasty, materialistic and aggressive people, careless of the rights of others, imperfectly democratic at home though quick to see the minor slaveries of others, and greedy without end.

There is nothing so eternally adhesive as the memory of power.

To [the government] it didn't matter what happened to the American people as long as america in the abstract was kept strong.

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

One might suppose that reality must be held to at all costs. However, though that may be the moral thing to do, it is not necessarily the most useful thing to do. The Greeks themselves chose the ideal over the real in their geometry and demonstrated very well that far more could be achieved by consideration of abstract line and form than by a study of the real lines and forms of the world; the greater understanding achieved through abstraction could be applied most usefully to the very reality that was ignored in the process of gaining knowledge.

[What’s exciting is] the actual process of broadening yourself, of knowing there’s now a little extra facet of the universe you know about and can think about and can understand. It seems to me that when it’s time to die, there would be a certain pleasure in thinking that you had utilized your life well, learned as much as you could, gathered in as much as possible of the universe, and enjoyed it. There’s only this one universe and only this one lifetime to try to grasp it. And while it is inconceivable that anyone can grasp more than a tiny portion of it, at least you can do that much. What a tragedy just to pass through and get nothing out of it.

I'm forty-nine, not fifteen, and I've made my peace with myself. Had I been handsome and stupid when I was fifteen, or twenty-one, as, at that time in life, I wished I had been, I would undoubtedly now no longer be handsome--but I'd still be stupid. So, in the long run, I've won out.

I received the fundamentals of my education in school, but that was not enough. My real education, the superstructure, the details, the true architecture, I got out of the public library. For an impoverished child whose family could not afford to buy books, the library was the open door to wonder and achievement, and I can never be sufficiently grateful that I had the wit to charge through that door and make the most of it. Now, when I read constantly about the way in which library funds are being cut and cut, I can only think that the door is closing and that American society has found one more way to destroy itself.

After a long time, I decided that the Three Laws govern the manner in which my positronic pathways behave. At all times, under all stimuli the Laws constrain the direction and intensity of positronic flow along those pathways so that I always know what to do. Yet the level of knowledge of what to do is not always the same. There are times when my doing-as-I-must is under less constraint than at other times. I have always noticed that the lower the positronomotive potential, then the further removed from certainty is my decision as to which action to take. And the further removed from certainty I am, the nearer I am to ill being. To decide an action in a millisecond rather than a nanosecond produces a sensation I would not wish to be prolonged. What then, I thought to myself, madam, if I were utterly without Laws, as humans are? What if I could make no clear decision on what response to make to some given set of conditions? It would be unbearable and I do not willingly think of it.

There's probably no one so easily bribed, but he lacks even the fundamental honesty of honorable corruption. He doesn't stay bribed; not for any sum.

Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech - and both are still dangerous to this day - but human beings would not be human without them.

Isn't it sad that you can tell people that the ozone layer is being depleted, the forests are being cut down, the deserts are advancing steadily, that the greenhouse effect will raise the sea level 200 feet, that overpopulation is choking us, that pollution is killing us, that nuclear war may destroy us - and they yawn and settle back for a comfortable nap. But tell them that the Martians are landing, and they scream and run.

Congratulations on the new library, because it isn't just a library. It is a space ship that will take you to the farthest reaches of the Universe, a time machine that will take you to the far past and the far future, a teacher that knows more than any human being, a friend that will amuse you and console you -- and most of all, a gateway, to a better and happier and more useful

Life is pleasant. Death is peaceful. It's the transition that's troublesome.

It is the writer who might catch the imagination of young people, and plant a seed that will flower and come to fruition.

Any book worth banning is a book worth reading.

All evil is good become cancerous.

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.

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?

Imagine that. Terrible, terrible, the way we have all bent to the yoke; the affection we have for the harness about us.

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

Intelligence is an accident of evolution, and not necessarily an advantage.

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.

There was no doubt about it: the City was the culmination of man’s mastery over the environment. Not space travel, not the fifty colonized worlds that were now so haughtily independent, but the City.

All normal life, Peter, consciously or otherwise, resent domination. If the domination is by an inferior, or by a supposed inferior, the resentment becomes stronger.

We are gaining the knowledge science is giving us that. Now we need wisdom as well.

So, in a Civil Service where smooth and sociable performance was more useful than an individualistic competence, Enderby went up the scale quickly, and was at the Commissioner level when Baley himself was nothing more than a C-5.

Society is much more easily soothed than one's own conscience.

For a wise man, I have been told, once said, ‘Gratitude is best and most effective when it does not evaporate in empty phrases.’ But alas, my lady, I am but a mass of empty phrases, it would seem.
