Arthur C. Clarke

"There may be a moral here. For the life of me I can't find it."

"“You’re a gang of robbers,” he said once. “You’re seeing how quickly you can loot this planet of its resources, and you don’t give a damn about the next generation.” “And what,” answered McKenzie, not very originally, “has the next generation ever done for us?”"

"For what is life but organized energy?"

"This sounded promising, and my coefficient of cupidity jumped several points."

"Why should men travel, he asked himself bitterly, across the gulf of stars at such expense and risk—merely to land on a spinning slag heap? For the same reason, he knew, that they had once struggled to reach Everest and the Poles and the far places of the Earth—for the excitement of the body that was adventure, and the more enduring excitement of the mind that was discovery."

"There was nothing like a museum for calming the mind, for putting the problems of everyday life in their true perspective. Here, surrounded by the infinite variety and wonder of Nature, he was reminded of truths he had forgotten. He was only one of a million million creatures that shared this planet Earth. The entire human race, with its hopes and fears, its triumphs and its follies, might be no more than an incident in the history of the world."

"It is hardly necessary for me to say that I do not believe in the supernatural; everything that happened has a perfectly rational explanation, obvious to any man with the slightest knowledge of psychology."

"The idea of death was utterly incongruous—as it is to all men until the final second."

"Christine would surely be talking, even if she had only an ape as audience. To her, any silence was as great a challenge as a blank canvas; it had to be filled with the sound of her own voice."

"The false logic involved is: “We exist; therefore something—call it X—created us.” Once this assumption is made, the properties of the hypothetical X can be fantasied in an unlimited number of ways. But the entire process is obviously fallacious; for by the same logic something must have created X—and so on. We are immediately involved in an infinite regress, which can have no meaning in the real universe."

"Grove was inclined to allow the request. “I can’t see how we can be harmed by allowing the destruction of what I don’t understand anyhow,” he said dryly. “And besides—you say it is your duty, Warrant Officer. I respect that. Time and space may flow like toffee, but duty endures.”"

"We have no idea what waits for us out there. We did not choose this situation, and whatever manner of creature or accident has stranded us here did not take much notice of our welfare. I would say nice moral questions are beside the point, and that pragmatism is the order of the day."

"Eumenes showed little taste for elaborate protocols; he was far too intelligent for that."

"Kolya believed that the Mongols’ expansion was pathological. It was a ghastly spiral of positive feedback, born of Genghis Khan’s unquestioned military genius and fueled by easy conquests, a plague of insanity and destruction that had spread across most of the known world."

"He says that even a god cannot conquer time, but nine hundred years should be enough for anybody."

"You know, we’re not used to secrecy up here. It’s not encouraged. We all have to work together to keep alive. Secrecy is corrosive, Professor, bad for morale."

"This project was no longer mathematics; it was engineering."

"Democracy is our most important possession. If we throw it away when the going gets tough, we might never get it back."

"Such craziness captured media attention, but was fortunately still rare."

"All the religiosity around worries me—doesn’t it you?"

"Slickness of presentation didn’t imply comprehensiveness of knowledge."

"When the pious fools come up against the godless pagans who own Judea, the result is what might be called diplomatic incidents."

"You do realize how many impossible things have to be true for that to have happened?"

"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’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.”"

"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!"

"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!"

"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."

"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..."

"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."

"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."

"Our lifetime may be the last that will be lived out in a technological society."

"The best proof that there's intelligent life in outer space is the fact that it hasn't come here."

"I don't believe in astrology; I'm a Sagittarius and we're skeptical."

"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."

"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."

"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.""

"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.""

"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."

"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."

"Any sufficiently advanced magic is indistinguishable from technology."

"Any technology distinguishable from magic is insufficiently advanced."

"Any technology that does not appear magical is insufficiently advanced."

"Any sufficiently advanced technology is indistinguishable from nature."

"Jede hinreichend fortgeschrittene Technologie ist von Magie nicht mehr zu unterscheiden."
