197 Quotes & Sayings By Isaac Asimov

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

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? Isaac Asimov

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 endures 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. Isaac Asimov

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. Isaac Asimov

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.] Isaac Asimov

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. . Isaac Asimov

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. Isaac Asimov

You must keep sending work out; you must never let a manuscript do nothing but eat its head off in a drawer. You send that work out again and again, while you're working on another one. If you have talent, you will receive some measure of success - but only if you persist. Isaac Asimov

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. . Isaac Asimov

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. Isaac Asimov

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. Isaac Asimov

..We now know the basic rules governing the universe, together with the gravitational interrelationships of its gross components, as shown in the theory of relativity worked out between 1905 and 1916. We also know the basic rules governing the subatomic particles and their interrelationships, since these are very neatly described by the quantum theory worked out between 1900 and 1930. What's more, we have found that the galaxies and clusters of galaxies are the basic units of the physical universe, as discovered between 1920 and 1930..The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong.. My answer to him was, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together. The basic trouble, you see, is that people think that 'right' and 'wrong' are absolute; that everything that isn't perfectly and completely right is totally and equally wrong. However, I don't think that's so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so. When my friend the English literature expert tells me that in every century scientists think they have worked out the universe and are always wrong, what I want to know is how wrong are they? Are they always wrong to the same degree? . Isaac Asimov

What would you consider a good job?" Answered as follows:" A good job is one in which I don't have to work, and get paid a lot of money." When I heard that I cheered and yelled and felt that he should be given an A+, for he had perfectly articulated the American dream of those who despise knowledge. What a politician that kid would have made. Isaac Asimov

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. Isaac Asimov

Q. You do not consider your statement a disloyal one? A. No, sir. Scientific truth is beyond loyalty and disloyalty. Q. Can you prove that this mathematics is valid? A. Only to another mathematician. Q. Your claim then is that your truth is of so esoteric a nature that it is beyond the understanding of a plain man. It seems to me that truth should be clearer than that, less mysterious, more open to the mind. A. It presents no difficulties to some minds. The physics of energy transfer, which we know as thermodynamics, has been clear and true through all the history of man since the mythical ages, yet there may be people present who would find it impossible to design a power engine. People of high intelligence, too. Isaac Asimov

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. . Isaac Asimov

In a properly automated and educated world, then, machines may prove to be the true humanizing influence. It may be that machines will do the work that makes life possible and that human beings will do all the other things that make life pleasant and worthwhile Isaac Asimov

People think of education as something that they can finish. And what’s more, when they finish, it’s a rite of passage. You’re finished with school. You’re no more a child, and therefore anything that reminds you of school - reading books, having ideas, asking questions - that’s kid’s stuff. Now you’re an adult, you don’t do that sort of thing any more. You have everybody looking forward to no longer learning, and you make them ashamed afterward of going back to learning. If you have a system of education using computers, then anyone, any age, can learn by himself, can continue to be interested. If you enjoy learning, there’s no reason why you should stop at a given age. People don’t stop things they enjoy doing just because they reach a certain age. 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. Isaac Asimov

Have you ever come across something you couldn't explain?"" Explain in what way? I could explain a ghost by saying, 'yes, that's a ghost.' I take it that's not what you mean. Isaac Asimov

A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension. I was sorry of the man who, it seemed to me, was forced to hover about the edges of science. He was compelled to shiver endlessly in the outskirts, getting only feeble warmth from the distant sun of science- in-progress; while I, just beginning my research, was bathed in the heady liquid heat up at the very center of the glow. In a lifetime of being wrong at many a point, I was never more wrong. It was I, not he, who was wandering in the periphery. It was he, not I, who lived in the blaze. I had fallen victim to the fallacy of the 'growing edge;' the belief that only the very frontier of scientific advance counted; that everything that had been left behind by that advance was faded and dead. But is that true? Because a tree in spring buds and comes greenly into leaf, are those leaves therefore the tree? If the newborn twigs and their leaves were all that existed, they would form a vague halo of green suspended in mid-air, but surely that is not the tree. The leaves, by themselves, are no more than trivial fluttering decoration. It is the trunk and limbs that give the tree its grandeur and the leaves themselves their meaning., 'it is because I have stood on the shoulders of giants. Isaac Asimov

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. Isaac Asimov

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. Isaac Asimov

And just how did you arrive at that remarkable conclusion, Mr. Mayor?""In a rather simple way. It merely required the use of that much-neglected commodity -- common sense. You see, there is a branch of human knowledge known as symbolic logic, which can be used to prune away all sorts of clogging deadwood that clutters up human language."" What about it?" said Fulham."I applied it. Among other things, I applied it to this document here. I didn't really need to for myself because I knew what it was all about, but I think I can explain it more easily to five physical scientists by symbols rather than by words." Hardin removed a few sheets of paper from the pad under his arm and spread them out. "I didn't do this myself, by the way, " he said. "Muller Holk of the Division of Logic has his name signed to the analyses, as you can see." Pirenne leaned over the table to get a better view and Hardin continued: "The message from Anacreon was a simple problem, naturally, for the men who wrote it were men of action rather than men of words. It boils down easily and straightforwardly to the unqualified statement, when in symbols is what you see, and which in words, roughly translated is, 'You give us what we want in a week, or we take it by force.'" There was silence as the five members of the Board ran down the line of symbols, and then Pirenne sat down and coughed uneasily. Hardin said, "No loophole, is there, Dr. Pirenne?""Doesn't seem to be. Isaac Asimov

I, on the other hand, am a finished product. I absorb electrical energy directly and utilize it with an almost one hundred percent efficiency. I am composed of strong metal, am continuously conscious, and can stand extremes of environment easily. These are facts which, with the self-evident proposition that no being can create another being superior to itself, smashes your silly hypothesis to nothing. . Isaac Asimov

It is possible to be too stable. No Outer World has colonized a new planet in two and a half centuries. are lives too long to risk and too comfortable to upset.“ I don’t know about that, Dr. Fastolfe. You’ve come to Earth. You risk disease.”“ Yes, I do. There are some of us, Mr. Baley, who feel that the future of the human race is even worth the possible loss of an extended lifetime. Too few of us, I am sorry to say.”“ In trying to introduce robots here on Earth, we’re doing our best to upset the balance of your City economy.”“ You mean you’re creating a growing group of displaced and declassified men on purpose?”“ Not out of cruelty or callousness, believe me. A group of displaced men, as you call them, are what we need to serve as a nucleus for colonization. Your ancient America was discovered by ships fitted out with men from the prisons. Don’t you see that the City’s womb has failed the displaced man. He has nothing to lose and worlds to gain by leaving Earth. . Isaac Asimov

A planet might deteriorate even if human beings existed upon it, if the society were itself abnormal and did not understand the importance of preserving the environment."" Surely, " said Pelorat, "such a society would quickly be destroyed. I don't think it would be possible for human beings to fail to understand the importance of retaining the very factors that are keeping them alive." Bliss said, "I don't have your pleasant faith in human reason, Pel. It seems to me to be quite conceivable that when a planetary society consists of Isolates, local and even individual concerns might easily by allowed to overcome planetary concerns. Isaac Asimov

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. Isaac Asimov

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. . Isaac Asimov

Despite all that education and experience can do, I retain a certain level of unsophistication that I cannot eradicate and that my friends find amusing. In fact, I think I sometimes detect conspiratorial plottings among my friends to protect me against my own lack of sophistication. I don't mind. I suspect that I am never quite as unsophisticated as they think I am, but I don't mind. Isaac Asimov

There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge. Isaac Asimov

The Imperial forces must keep their hands off, but they find that they can do much even so. Each sector is encouraged to be suspicious of its neighbors. Within each sector, economic and social classes are encouraged to wage a kind of war with each other. The result is that all over Trantor it is impossible for the people to take united action. Everywhere, the people would rather fight each other than make a common stand against the central tyranny and the Empire rules without having to exert force. Isaac Asimov

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. Isaac Asimov

Frustration of my plans to lighten the disaster will convince people that the future holds no promise for them. Already they recall the lives of their grandfathers with envy. They will see that political revolutions and trade stagnations will increase. The feeling will pervade the Galaxy that only what a man can grasp for himself at that moment will be of any account. Ambitious men will not wait and unscrupulous men will not hang back. By their every action they will hasten the decay of the worlds. Isaac Asimov

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. Isaac Asimov

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. Isaac Asimov

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

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. Isaac Asimov

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 Isaac Asimov

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

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

The Scientist - with capital letters and no smile. Isaac Asimov

Every period of human development has had its own particular type of human conflict---its own variety of problem that, apparently, could be settled only by force. And each time, frustratingly enough, force never really settled the problem. Instead, it persisted through a series of conflicts, then vanished of itself---what's the expression---ah, yes, 'not with a bang, but a whimper, ' as the economic and social environment changed. And then, new problems, and a new series of wars. . Isaac Asimov

The action of social revolution and the reaction of guarding against such revolution or combating it once it has begun are the causes of a great deal of the human misery with which history is permeated. Isaac Asimov

I shall not be alive a half decade hence, ” said Seldon, “and yet it is of overpowering concern to me. Call it idealism. Call it an identification of myself with that mystical generalization to which we refer by the term, ‘man. Isaac Asimov

The troubles of modern life come from being divorced from nature. Isaac Asimov

Human beings sometimes find a kind of pleasure in nursing painful emotions, in blaming themselves without reason or even against reason. Isaac Asimov

If I had felt then as I feel now, or as I felt a few years after I had married her, nothing could possibly have persuaded me to marry a woman who smoked. Dates, yes. Sexual adventures, yes. But to pin myself permanently inside closed quarters with a smoker? Never. Never. Never. Beauty wouldn't count, sweetness wouldn't count, suitability in every other respect wouldn't count. Isaac Asimov

Married life had taught him the futility of arguing with a female in a dark-brown mood. Isaac Asimov

Married life had taught Toran the futility of arguing with a female in dark-brown mood. He shrugged, and left her. Isaac Asimov

There never can be a man so lost as one who is lost in the vast and intricate corridors of his own lonely mind, where none may reach and none may save. Isaac Asimov

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. Isaac Asimov

Civilizations have always been pyramidal in structure. As one climbs toward the apex of the social edifice, there is increased leisure and increasing opportunity to pursue hapiness. As one climbs, one finds also fewer and fewer people to enjoy this more and more. Invariably, there is a preponderance of the dispossessed. And remember this, no matter how well off the bottom layers of the pyramid might be on an absolute scale, they are always dispossessed in comparison with the apex. Isaac Asimov

The Solarians have given up something mankind has had for a million years; something worth more than atomic power, cities, agriculture, tools, fire, everything; because it's something that made everything possible (...) The tribe, sir. Cooperation between individuals. Isaac Asimov

It seems to me, Golan, that the advance of civilization is nothing but an exercise in the limiting of privacy. Isaac Asimov

In all the known history of Mankind, advances have been made primarily in physical technology; in the capacity of handling the inanimate world about Man. Control of self and society has been left to to chance or to the vague gropings of intuitive ethical systems based on inspiration and emotion. As a result no culture of greater stability than about fifty-five percent has ever existed, and these only as the result of great human misery. Isaac Asimov

Flattery is useful when dealing with youngsters. Isaac Asimov

A person willing to fly in the face of reason, authority, and common sense must be a person of considerable self-assurance. Since he occurs only rarely, he must seem eccentric (in at least that respect) to the rest of us. A person eccentric in one respect is often eccentric in others. Consequently, the person who is most likely to get new ideas is a person of good background in the field of interest and one who is unconventional in his habits. (To be a crackpot is not, however, enough in itself.) . Isaac Asimov

Any system which allows men to choose their own future will end by choosing safety and mediocrity, and in such a Reality the stars are out of reach. Isaac Asimov

Gadgetry will continue to relieve mankind of tedious jobs. Kitchen units will be devised that will prepare ‘automeals, ’ heating water and converting it to coffee; toasting bread; frying, poaching or scrambling eggs, grilling bacon, and so on. Breakfasts will be ‘ordered’ the night before to be ready by a specified hour the next morning. Communications will become sight-sound and you will see as well as hear the person you telephone. The screen can be used not only to see the people you call but also for studying documents and photographs and reading passages from books. Synchronous satellites, hovering in space will make it possible for you to direct-dial any spot on earth, including the weather stations in Antarctica. [M]en will continue to withdraw from nature in order to create an environment that will suit them better. By 2014, electroluminescent panels will be in common use. Ceilings and walls will glow softly, and in a variety of colors that will change at the touch of a push button. Robots will neither be common nor very good in 2014, but they will be in existence. The appliances of 2014 will have no electric cords, of course, for they will be powered by long- lived batteries running on radioisotopes.“[ H]ighways … in the more advanced sections of the world will have passed their peak in 2014; there will be increasing emphasis on transportation that makes the least possible contact with the surface. There will be aircraft, of course, but even ground travel will increasingly take to the air a foot or two off the ground. [V]ehicles with ‘Robot-brains’ … can be set for particular destinations … that will then proceed there without interference by the slow reflexes of a human driver. [W]all screens will have replaced the ordinary set; but transparent cubes will be making their appearance in which three-dimensional viewing will be possible. [T]he world population will be 6, 500, 000, 000 and the population of the United States will be 350, 000, 000. All earth will be a single choked Manhattan by A.D. 2450 and society will collapse long before that! There will, therefore, be a worldwide propaganda drive in favor of birth control by rational and humane methods and, by 2014, it will undoubtedly have taken serious effect. Ordinary agriculture will keep up with great difficulty and there will be ‘farms’ turning to the more efficient micro-organisms. Processed yeast and algae products will be available in a variety of flavors. The world of A.D. 2014 will have few routine jobs that cannot be done better by some machine than by any human being. Mankind will therefore have become largely a race of machine tenders. Schools will have to be oriented in this direction…. All the high-school students will be taught the fundamentals of computer technology will become proficient in binary arithmetic and will be trained to perfection in the use of the computer languages that will have developed out of those like the contemporary “Fortran". [M]ankind will suffer badly from the disease of boredom, a disease spreading more widely each year and growing in intensity. This will have serious mental, emotional and sociological consequences, and I dare say that psychiatry will be far and away the most important medical specialty in 2014. [T]he most glorious single word in the vocabulary will have become work! in our a society of enforced leisure. Isaac Asimov

Humanity has the stars in its future, and that future is too important to be lost under the burden of juvenile folly and ignorant superstition. Isaac Asimov

I believe that only scientists can understand the universe. It is not so much that I have confidence in scientists being right, but that I have so much in nonscientists being wrong. Isaac Asimov

It's your fiction that interests me. Your studies of the interplay of human motives and emotion. Isaac Asimov

[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. Isaac Asimov

You are never too old to learn more than you already know and to become able to do more than you already can. Isaac Asimov

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. Isaac Asimov

John Dalton's records, carefully preserved for a century, were destroyed during the World War II bombing of Manchester. It is not only the living who are killed in war. Isaac Asimov

It was a long time since he'd done any actual clinical work, and obviously his sojourn among the academics at Saro University had attenuated the professional detachment that allows members of the healing arts to confront the ill without being overwhelmed by compassion and sorrow. He was surprised at that, how tenderhearted he seemed to have become, how thin-skinned. Isaac Asimov

Past glories are poor feeding. Isaac Asimov

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

All roads lead to Trantor, and that is where all stars end. Isaac Asimov

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.. . Isaac Asimov

All evil is good become cancerous. Isaac Asimov

The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong. The young man then quoted with approval what Socrates had said on learning that the Delphic oracle had proclaimed him the wisest man in Greece. 'If I am the wisest man, ' said Socrates, 'it is because I alone know that I know nothing.' The implication was that I was very foolish because I was under the impression I knew a great deal. Alas, none of this was new to me. (There is very little that is new to me; I wish my correspondents would realize this.) This particular theme was addressed to me a quarter of a century ago by John Campbell, who specialized in irritating me. He also told me that all theories are proven wrong in time. My answer to him was, 'John, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together. . Isaac Asimov

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 -- has become crucial to our salvation, if we are to be saved at all. Isaac Asimov
