Arthur C. Clarke

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.

Any technology that does not appear magical is insufficiently advanced.

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.

Any sufficiently advanced magic is indistinguishable from technology.

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.

Just as the human memory is not a passive recorder but a tool in the construction of the self, so history has never been a simple record of the past, but a means of shaping peoples.

It is later than you think. May it not be true for this Sundial.

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.

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.

Maybe those nihilist philosophers are right; maybe this is all we can expect of the universe, a relentless crushing of life and spirit, because the equilibrium state of the cosmos is death...

A single test which proves some piece of theory wrong is more valuable than a hundred tests showing that idea might be true.

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.

I don't believe in God but I'm very interested in her.

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.

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.

All these worlds are yours, except Europa. Attempt no landings there.

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.

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.

I don't pretend we have all the answers. But the questions are certainly worth thinking about..

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; and 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.
