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.
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 set off the fire alarm and have nothing to do but to wait.
I do not think we will have to wait for long.
Science demands patience.
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 the 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.
We stand now at the turning point between two eras. Behind us is a past to which we can never return...
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.
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, and thermonuclear weapons.
All these worlds are yours, except Europa. Attempt no landings there.
Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.
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.
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.
