"Science demands patience."
"A single test which proves some piece of theory wrong is more valuable than a hundred tests showing that idea might be true."
"What we need is a machine that will let us see the other guyβs point of view."
"If the house is to be demolished tomorrow anyhow, people seem to feel, we may as well burn the furniture today. None of our problems are insoluble...But it seems clear that to prevail we humans will have to act with a smartness and selflessness that has so far eluded us during our long and tangled history."
"If children have interests then education happens."
"2001 was written in an age which now lies beyond one of the great divides in human history; we are sundered from it forever by the moment when Neil Armstrong and Buzz Aldrin stepped out on to the Sea of Tranquility. Now history and fiction have become inexorably intertwined."
"I don't believe in God but I'm very interested in her."
"SETI is probably the most important quest of our time, and it amazes me that governments and corporations are not supporting it sufficiently."
"The best measure of a man's honesty isn't his income tax return. It's the zero adjust on his bathroom scale."
"There is hopeful symbolism in the fact that flags do not wave in a vacuum."
"The Information Age offers much to mankind, and I would like to think that we will rise to the challenges it presents. But it is vital to remember that information β in the sense of raw data β is not knowledge, that knowledge is not wisdom, and that wisdom is not foresight. But information is the first essential step to all of these."
"I don't pretend we have all the answers. But the questions are certainly worth thinking about.."
"I've been saying for a long time that I'm hoping to find intelligent life in Washington ... I'm reasonably sure there must be life in this solar system, on Mars or on Europa, and other places. I think life is probably going to be ubiquitous, though we still don't have any proof of that yet β and still less, any proof of intelligent life anywhere. But I hope that will be coming in the next decade or so through radio astronomy or, perhaps, the discovery of objects in space which are obviously artificial. Astronomical engineering β that may be the other thing to look for."
"The danger of asteroid or comet impact is one of the best reasons for getting into space ... I'm very fond of quoting my friend Larry Niven: "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!""
"We should be less concerned about adding years to life, and more about adding life to years. I have been very fortunate to have witnessed some of humanity's greatest achievements during the 20th century that is nearing its end. Yet we must admit that it has also been the most savage century in the history of our kind. If I can have one more wish, I want to see lasting and meaningful peace achieved in Sri Lanka as early as possible. But I am aware that peace cannot just be wished; it involves hard work, courage and persistence. As we welcome 2001, let us harness our collective energies to create a culture of peace and a land of prosperity."
"The intelligent minority of this world will mark 1 January 2001 as the real beginning of the 21st century and the Third Millennium."
"It has yet to be proven that intelligence has any survival value."
"Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying."
"There is the possibility that humankind can outgrow its infantile tendencies, as I suggested in Childhood's End. But it is amazing how childishly gullible humans are. There are, for example, so many different religions β each of them claiming to have the truth, each saying that their truths are clearly superior to the truths of others β how can someone possibly take any of them seriously? I mean, that's insane. ...Though I sometimes call myself a crypto-Buddhist, Buddhism is not a religion. Of those around at the moment, Islam is the only one that has any appeal to me. But, of course, Islam has been tainted by other influences. The Muslims are behaving like Christians, I'm afraid."
"The dinosaurs disappeared because they could not adapt to their changing environment. We shall disappear if we cannot adapt to an environment that now contains spaceships, computers β and thermonuclear weapons."
"Finally, I would like to assure my many Buddhist, Christian, Hindu, Jewish, and Muslim friends that I am sincerely happy that the religion which Chance has given you has contributed to your peace of mind (and often, as Western medical science now reluctantly admits, to your physical well-being). Perhaps it is better to be un-sane and happy, than sane and un-happy. But it is best of all to be sane and happy. Whether our descendants can achieve that goal will be the greatest challenge of the future. Indeed, it may well decide whether we have any future. p. 97, Acknowledgements"
"The search for alien artefacts in the Solar System should be a perfectly legitimate branch of science ('exoarchaeology'?). Unfortunately, it has been largely discredited by claims that such evidence has already been found - and has been deliberately suppressed by NASA! p. 97, Acknowledgements"
"Their little universe is very young, and its god is still a child. But it is too soon to judge them; when We return in the Last Days, We will consider what should be saved. p. 88, Epilogue"
"Whatever godlike powers and principalities lurked beyond the stars, Poole reminded himself, for ordinary humans only two things were important - Love and Death. p. 87"
"Although Poole sometimes missed the cops-and-robbers dramas he had often enjoyed in his youth, he had grown to accept the current wisdom: excessive interest in pathological behaviour was itself pathological. p. 73"
"Since women are better at producing babies, presumably Nature has given men some talent to compensate. But for the moment I can't think of it."
"Through long and bitter experience, Rajasinghe had learned never to trust first impressions, but also never to ignore them."
"This is the first age that's ever paid much attention to the future, which is a little ironic since we may not have one."
"β¦ we have a situation in which millions of vehicles, each a miracle of often unnecssary complication, are hurtling in all directions under the impulse of anything up to 200 horsepower. Many of them are the size of small houses and contain a couple of tons of sophisticated alloys β yet often carry a single passenger. They can travel at a hundred miles an hour, but are lucky if they average forty. In one lifetime they have consumed more irreplaceable fuel than has been used in the whole previous history of mankind. The roads to support them, inadequate though they are, cost as much as a small war; the analogy is a good one, for the casualties are on the same scale."
"The Ramans do everything in threes."
"Perhaps our role on this planet is not to worship God β but to create Him."
"One of the biggest roles of science fiction is to prepare people to accept the future without pain and to encourage a flexibility of mind. Politicians should read science fiction, not westerns and detective stories. Two-thirds of 2001 is realistic β hardware and technology β to establish background for the metaphysical, philosophical, and religious meanings later."
"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 β in science, politics, art, or whatever β seems to evoke three stages of reaction. They may be summed up by the phrases:(1) "It's completely impossible β 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 β 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 β 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 β or third β 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 β 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. Thatβs 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."
