"I'm sure the universe is full of intelligent life. It's just been too intelligent to come here."
"It is later than you think. May it not be true for this Sundial."
"CNN is one of the participants in the war. I have a fantasy where Ted Turner is elected president but refuses because he doesn't want to give up power."
"The greatest tragedy in mankind's entire history may be the hijacking of morality by religion."
"The fact that we have not yet found the slightest evidence for life — much less intelligence — beyond this Earth does not surprise or disappoint me in the least. Our technology must still be laughably primitive, we may be like jungle savages listening for the throbbing of tom-toms while the ether around them carries more words per second than they could utter in a lifetime."
"I have encountered a few "creationists" and because they were usually nice, intelligent people, I have been unable to decide whether they were really mad, or only pretending to be mad. If I was a religious person, I would consider creationism nothing less than blasphemy. Do its adherents imagine that God is a cosmic hoaxer who has created the whole vast fossil record for the sole purpose of misleading humankind? And, although I do not necessarily agree with the paleontologist Teilhard de Chardin's advocacy of evolution as a major proof of the glory of God, de Chardin's attitude is both logical and inspiring. A creator who laid the foundations for the entire future at the beginning of time is far more awesome than a clumsy tinkerer who constantly modifies his creations and throws away entire species in the process."
"I would defend the liberty of consenting adult creationists to practice whatever intellectual perversions they like in the privacy of their own homes; but it is also necessary to protect the young and innocent."
"I wanted to kill myself. I would have done it, too, if I had owned a gun. I was considering the gruesome alternatives — pills, slitting my wrists with a razor blade, jumping off a bridge — when another student called to ask me a detailed question on relativity. There was no way, after fifteen minutes of thinking about Mr. Einstein, that suicide was still a viable option. Divorce, certainly. Celibacy, highly likely. But death was out of the question. I could never have prematurely terminated my love affair with physics."
"All these worlds are yours, except Europa. Attempt no landings there."
"Plans for the final assault on Big Brother had already been worked out and agreed upon with Mission Control. Leonov would move in slowly, probing at all frequencies, and with steadily increasing power — constantly reporting back to Earth at every moment. When final contact was made, they would try to secure samples by drilling or laser spectroscopy; no one really expected these endeavours to succeed, as even after a decade of study TMA-1 resisted all attempts to analyse its material. The best efforts of human scientists in this direction seemed comparable to those of Stone Age men trying to break through the armour of a bank vault with flint axes."
"Any teacher that can be replaced by a machine should be!"
"The fates could not possibly be so malevolent, now that he had only a few hundred meters to go. He was whistling in the dark, of course. How many aircraft had crashed at the very edge of the runway, after safely crossing an ocean? How many times had machines or muscles failed when there were only millimeters to go? Every possible piece of luck, bad as well as good, happened to somebody, somewhere. He had no right to expect any special treatment."
"One fail-safe after another had let them down. Helped by the ionospheric storm, the sheer perversity of inanimate things struck again."
"Long ago, he had made that choice between work and life that can seldom be avoided at the highest levels of human endeavor ... Any fool could shuffle genes, and most did. But whether or not history gave him credit, few men could have achieved what he had done — and was about to do."
"Belief in God is apparently a psychological artifact of mammalian reproduction."
"There was no substitute for reality; one should be aware of imitations."
"Meanwhile, among all its countless other effects upon human culture, Starglider had brought to its climax a process that was already well under way. It had put an end to the billions of the words of pious gibberish with which apparently intelligent men had addled their minds for centuries."
"The hypothesis you refer to as God, though not disprovable by logic alone, is unnecessary for the following reason. If you assume that the universe can be quote explained unquote as the creation of an entity known as God, he must obviously be of a higher degree of organization than his product. Thus you have more than doubled the size of the original problem, and have taken the first step on a diverging infinite regress. William of Ockham pointed out as recently as your fourteenth century that entities should not be multiplied unnecessarily. I cannot therefore understand why this debate continues."
"I am unable to distinguish clearly between your religious ceremonies and apparently identical behavior at the sporting and cultural functions you have transmitted to me."
"Even though you were once a goddess, Kalidasa's heaven was only an illusion."
"“I am the King.” Ah, but which king? The monarch who had stood on these granite flagstones — scarcely worn then, eighteen hundred years ago — was probably an able and intelligent man; but he failed to conceive that the time could ever come when he would fade into an anonymity as deep as that of his humblest subjects."
"Clarke's Third Law doesn't work in reverse. Given that "any sufficiently advanced technology is indistinguishable from magic," it does not follow that "any magical claim that anybody may make at any time is indistinguishable from a technological advance that will come some time in the future." ... There have admittedly been occasions when authoritative, pontificating skeptics have come away with egg on their faces, even within their own lifetimes. But there have been a far greater number of occasions when magical claims have never been vindicated. An apparent magical claim might eventually turn out to be true. In any age there are so many magical claims that are, or could be, made. They can't all be true; many are mutually contradictory. We have no reason to suppose that, simply by the act of sitting down and dreaming up a magical claim, we shall make it come true in some future technology. Some things that would surprise us today will come true in the future. But lots and lots of things that would surprise us today will not come true ever."
"Any sufficiently advanced technology is indistinguishable from nature."
"Any technology that does not appear magical is insufficiently advanced."
"Any technology distinguishable from magic is insufficiently advanced."
"Any sufficiently advanced magic is indistinguishable from technology."
"When an official declares something false, chances are that it is. When he or she says it is absolutely false, chances are it is true. ... The overemphasis sticks out like Pinocchio's nose."
"When, however, the lay public rallies round an idea that is denounced by distinguished but elderly scientists and supports that idea with great fervor and emotion — the distinguished but elderly scientists are then, after all, probably right."
"It is significant how extremely difficult it has been even for the prophetic writers of science fiction to imagine and accept an unknown future. At the close of Childhood's End, the English author and scientist Arthur Clarke wrote: "The stars are not for men.""
"In "Credo," an essay published in 1991, Clarke lays out a belief system by distinguishing between two views of God: Alpha, who "rewards good and evil in some vaguely described afterlife," and Omega, "Creator of Everything … a much more interesting character and not so easily dismissed." Clarke writes, "No intelligent person can contemplate the night sky without a sense of awe. The mind-boggling vista of exploding supernovae and hurtling galaxies does seem to require a certain amount of explaining.""
"One of the English science-fiction writers once said, "Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering." ... I must say I agree with him."
"we hadn't gotten as far as another science fiction writer thought we might have. Arthur Clarke I mean…I was sort of rooting for what he had in mind, the good parts of it anyway...The idea of greater space travel and almost casual space travel. I grew up during the Space Race, during the sixties, and it was a wonderful way of sort of having a way without having one. We could get the technological push, and we could get the combat with the Soviet Union, but we never quite had that nuclear war. Instead we raced each other to the moon, and I guess I see space still as a way to achieve a lot of technological efforts without necessarily hurting anybody."
"I don't believe in astrology; I'm a Sagittarius and we're skeptical."
"The best proof that there's intelligent life in outer space is the fact that it hasn't come here."
"Our lifetime may be the last that will be lived out in a technological society."
"I'm sometimes asked how I would like to be remembered. I've had a diverse career as a writer, underwater explorer, space promoter and science populariser. Of all these, I want to be remembered most as a writer — one who entertained readers, and, hopefully, stretched their imagination as well."
"If I may be allowed just three wishes, they would be these. Firstly, I would like to see some evidence of extra-terrestrial life. I have always believed that we are not alone in the universe. But we are still waiting for ETs to call us — or give us some kind of a sign. We have no way of guessing when this might happen — I hope sooner rather than later! Secondly, I would like to see us kick our current addiction to oil, and adopt clean energy sources. ... Climate change has now added a new sense of urgency. Our civilisation depends on energy, but we can't allow oil and coal to slowly bake our planet... The third wish is one closer to home. I've been living in Sri Lanka for 50 years — and half that time, I've been a sad witness to the bitter conflict that divides my adopted country. I dearly wish to see lasting peace established in Sri Lanka as soon as possible."
"Communication technologies are necessary, but not sufficient, for us humans to get along with each other. This is why we still have many disputes and conflicts in the world. Technology tools help us to gather and disseminate information, but we also need qualities like tolerance and compassion to achieve greater understanding between peoples and nations. I have great faith in optimism as a guiding principle, if only because it offers us the opportunity of creating a self-fulfilling prophecy. So I hope we've learnt something from the most barbaric century in history — the 20th. I would like to see us overcome our tribal divisions and begin to think and act as if we were one family. That would be real globalisation..."
"In my time I've been very fortunate to see many of my dreams come true! Growing up in the 1920s and 1930s, I never expected to see so much happen in the span of a few decades. We "space cadets" of the British Interplanetary Society spent all our spare time discussing space travel — but we didn't imagine that it lay in our own near future... I still can't quite believe that we've just marked the 50th anniversary of the Space Age! We've accomplished a great deal in that time, but the "Golden Age of Space" is only just beginning. Over the next 50 years, thousands of people will travel to Earth orbit — and then, to the Moon and beyond. Space travel — and space tourism — will one day become almost as commonplace as flying to exotic destinations on our own planet."
"I now spend a good part of my day dreaming of times past, present and future. As I try to survive on 15 hours sleep a day, I have plenty of time to enjoy vivid dreams. Being completely wheel-chaired doesn't stop my mind from roaming the universe — on the contrary!"
"As I approach my 90th birthday, my friends are asking how it feels like, to have completed 90 orbits around the Sun. Well, I actually don't feel a day older than 89!"
"“You’re not too heavily laden, Professor. What are those documents?” “Star charts,” he said firmly. “The true treasure of our civilization. A few books too—oh, what a horror it was that we were not able to empty the libraries! For once a book is lost to the ice, a little more of our past is gone forever. But as to my personal effects, my pots and pans, I have my own troop of slave bearers to help me with all that. They are called graduate students.”"
"Maybe it’s a mark of a maturing culture, do you think, that secrets aren’t kept, that truth is told, that things are talked out?"
"You do realize how many impossible things have to be true for that to have happened?"
"When the pious fools come up against the godless pagans who own Judea, the result is what might be called diplomatic incidents."
"Slickness of presentation didn’t imply comprehensiveness of knowledge."
"All the religiosity around worries me—doesn’t it you?"
"Such craziness captured media attention, but was fortunately still rare."
"Democracy is our most important possession. If we throw it away when the going gets tough, we might never get it back."
"This project was no longer mathematics; it was engineering."
