"The rash assertion that 'God made man in His own image' is ticking like a time bomb at the foundation of many faiths, and as the hierarchy of the universe is disclosed to us, we may have to recognize this chilling truth: if there are any gods whose chief concern is man, they cannot be very important gods."

"We cannot predict the new forces, powers, and discoveries that will be disclosed to us when we reach the other planets and set up new laboratories in space. They are as much beyond our vision today as fire or electricity would be beyond the imagination of a fish."

"We seldom stop to think that we are still creatures of the sea, able to leave it only because, from birth to death, we wear the water-filled space suits of our skins."

"I am afraid that this chapter will amply demonstrate the truth of Clarke's 69th Law, viz., "Reading computer manuals without the hardware is as frustrating as reading sex manuals without the software." In both cases the cure is simple though usually very expensive."

"Clarke's Law of Revolutionary Ideas: Every revolutionary idea — in science, politics, art, or whatever — seems to evoke three stages of reaction. They may be summed up by the phrases:(1) "It's completely impossible — don't waste my time"; (2) "It's possible, but it's not worth doing"; (3) "I said it was a good idea all along.""

"Clarke's Third Law: Any sufficiently advanced technology is indistinguishable from magic."

"Clarke's Second Law: The only way of discovering the limits of the possible is to venture a little way past them into the impossible."

"Clarke's First Law: When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."

"When you are next out of doors on a summer night, turn your head towards the zenith. Almost vertically above you will be shining the brightest star of the northern skies — Vega of the Lyre, twenty-six years away at the speed of light, near enough to the point of no return for us short-lived creatures. Past this blue-white beacon, fifty times as brilliant as our sun, we may send our minds and bodies, but never our hearts. For no man will ever turn homewards beyond Vega, to greet again those he knew and loved on Earth."

"Space can be mapped and crossed and occupied without definable limit; but it can never be conquered. When our race has reached its ultimate achievements, and the stars themselves are scattered no more widely than the seed of Adam, even then we shall still be like ants crawling on the face of the Earth. The ants have covered the world, but have they conquered it — for what do their countless colonies know of it, or of each other? So it will be with us as we spread out from Earth, loosening the bonds of kinship and understanding, hearing faint and belated rumors at second — or third — or thousandth hand of an ever dwindling fraction of the entire human race. Though the Earth will try to keep in touch with her children, in the end all the efforts of her archivists and historians will be defeated by time and distance, and the sheer bulk of material. For the numbers of distinct human societies or nations, when our race is twice its present age, may be far greater than the total number of all the men who have ever lived up to the present time. We have left the realm of comprehension in our vain effort to grasp the scale of the universe; so it must ever be, sooner rather than later."

"To obtain a mental picture of the distance to the nearest star, compared to the nearest planet, you must imagine a world in which the closest object to you is only five feet away — and there is nothing else to see until you have travelled a thousand miles."

"We have abolished space here on the little Earth; we can never abolish the space that yawns between the stars. Once again, as in the days when Homer sang, we are face-to-face with immensity and must accept its grandeur and terror, its inspiring possibilities and its dreadful restraints."

"When the pioneers and adventurers of our past left their homes in search of new lands, they said good-bye forever to the place of their birth and the companions of their youth. Only a lifetime ago, parents waved farewell to their emigrating children in the virtual certainty that they would never meet again. And now, within one incredible generation, all this has changed."

"Our age is in many ways unique, full of events and phenomena that never occurred before and can never happen again. They distort our thinking, making us believe that what is true now will be true forever, though perhaps on a larger scale. Because we have annihilated distance on this planet, we imagine that we can do it once again. The facts are otherwise, and we see them more clearly if we forget the present and turn our minds towards the past."

"The goal of the future is full unemployment, so we can play. That’s why we have to destroy the present politico-economic system."

"Behind every man now alive stand 30 ghosts, for that is the ratio by which the dead outnumber the living."

"As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying."

"Human judges can show mercy. But against the laws of nature, there is no appeal."

"Yet now, as he roared across the night sky toward an unknown destiny, he found himself facing that bleak and ultimate question which so few men can answer to their satisfaction. What have I done with my life, he asked himself, that the world will be poorer if I leave it."

"They will have time enough, in those endless aeons, to attempt all things, and to gather all knowledge ... no Gods imagined by our minds have ever possessed the powers they will command ... But for all that, they may envy us, basking in the bright afterglow of Creation; for we knew the Universe when it was young."

"He had discharged his destiny; now, perhaps, he could begin to live."

"It is not my duty as an historian to predict the future, only to observe and interpret the past. But its lesson is clear enough; we have lived too long out of contact with reality, and now the time has come to rebuild our lives."

"All explorers are seeking something they have lost. It is seldom that they find it, and more seldom still that the attainment brings them greater happiness than the quest."

"After a while Hilvar did his best to steer the conversation away from these meaningless morasses of theology in order to concentrate on the ascertainable facts."

"The fact was that he suffered from an incurable malady which, it seemed, attacked only Homo sapiens among all the intelligent races of the universe. That disease was religious mania. Throughout the earlier part of its history, the human race had brought forth an endless succession of prophets, seers, messiahs, and evangelists who convinced themselves and their followers that to them alone were the secrets of the universe revealed. Some of them succeeded in establishing religions which survived for many generations and influenced billions of men; others were forgotten even before their deaths. The rise of science, which with monotonous regularity refuted the cosmologies of the prophets and produced miracles which they could never match, eventually destroyed all these faiths. It did not destroy the awe, not the reverence and humility, which all intelligent beings felt as they contemplated the stupendous universe in which they found themselves. What it did weaken, and finally obliterate, were the countless religions, each of which claimed with unbelievable arrogance, that it was the sole repository of the truth and that its millions of rivals and predecessors were all mistaken."

"There was only one thing of which he could be certain now. Boredom would not be a serious problem for a considerable time to come."

"Khedron was content with the order of things as it was. True, he might upset that order from time to time—but only by a little. He was a critic, not a revolutionary. On the placidly flowing river of time, he wished only to make a few ripples; he shrank from diverting its course."

"There still remained, for all men to share, the linked worlds of love and art. Linked, because love without art is merely the slaking of desire, and art cannot be enjoyed unless it is approached with love."

"Somewhere back at the beginning I was chosen to be Jester, and there is only one Jester at a time in Diaspar. Most people think that is one too many."

"If the artist did not know his goal, even the most miraculous of tools could not find it for him."

"Overhead, without any fuss, the stars were going out."

"Science can destroy religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the non-existence of Zeus or Thor — but they have few followers now."

"We stand now at the turning point between two eras. Behind us is a past to which we can never return ... The coming of the rocket brought to an end a million years of isolation ... the childhood of our race was over and history as we know it began."

"Others, one suspects, are afraid that the crossing of space, and above all contact with intelligent but nonhuman races, may destroy the foundations of their religious faith. They may be right, but in any event their attitude is one which does not bear logical examination — for a faith which cannot survive collision with the truth is not worth many regrets."

"It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars."

"If we have learned one thing from the history of invention and discovery, it is that, in the long run — and often in the short one — the most daring prophecies seem laughably conservative."

"I can never look now at the Milky Way without wondering from which of those banked clouds of stars the emissaries are coming. If you will pardon so commonplace a simile, we have broken the glass of the fire-alarm and have nothing to do but to wait. I do not think we will have to wait for long"

"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."
