Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.

Philosophy [nature] is written in that great book which ever is before our eyes — I mean the universe — but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.

There is a wide yawning black infinity. In every direction the extension is endless, the sensation of depth is overwhelming. And the darkness is immortal. Where light exists, it is pure, blazing, fierce; but light exists almost nowhere, and the blackness itself is also pure and blazing and fierce. But most of all, there is very nearly nothing in the dark; except for little bits here and there, often associated with the light, this infinite receptacle is empty.

This picture is strangely frightening. It should be familiar. It is our universe.

Even these stars, which seem so numerous, are, as sand, as dust, or less than dust, in the enormity of the space in which there is nothing. Nothing! We are not without empathetic terror when we open Pascal’s Pensées and read, 'I am the great silent spaces between worlds.'

[From an undated, handwritten piece of text from the early 1950s which Sagan wrote when he was an undergraduate at the University of Chicago]

Across the sea of space, the stars are other suns.

"How quickly we grow accustomed to wonders. I am reminded of the Isaac Asimov story "Nightfall," about the planet where the stars were visible only once in a thousand years. So awesome was the sight that it drove people mad. We who can see the stars every night glance up casually at the cosmos and then quickly down again, searching for a Dairy Queen."

An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

Discover the force of the skies O Men: once recognised it can be put to use.

"You would hardly think, at first, that horrid monsters lie up there waiting to be discovered by any moderately penetrating mind — monsters to which those of the oceans bear no sort of comparison."

What monsters may they be?"

Impersonal monsters, namely, Immensities. Until a person has thought out the stars and their inter-spaces, he has hardly learnt that there are things much more terrible than monsters of shape, namely, monsters of magnitude without known shape. Such monsters are the voids and waste places of the sky... In these our sight plunges quite beyond any twinkler we have yet visited. Those deep wells for the human mind to let itself down into, leave alone the human body! and think of the side caverns and secondary abysses to right and left as you pass on!...

There is a size at which dignity begins," he exclaimed; "further on there is a size at which grandeur begins; further on there is a size at which solemnity begins; further on, a size at which awfulness begins; further on, a size at which ghastliness begins. That size faintly approaches the size of the stellar universe. So am I not right in saying that those minds who exert their imaginative powers to bury themselves in the depths of that universe merely strain their faculties to gain a new horror?"

"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam."

The bright sun was extinguish'd, and the stars
Did wander darkling in the eternal space.

Attempts to locate oneself within history are as natural, and as absurd, as attempts to locate oneself within astronomy. On the day that I was born, 13 April 1949, nineteen senior Nazi officials were convicted at Nuremberg, including Hitler's former envoy to the Vatican, Baron Ernst von Weizsacker, who was found guilty of planning aggression against Czechoslovakia and committing atrocities against the Jewish people. On the same day, the State of Israel celebrated its first Passover seder and the United Nations, still meeting in those days at Flushing Meadow in Queens, voted to consider the Jewish state's application for membership. In Damascus, eleven newspapers were closed by the regime of General Hosni Zayim. In America, the National Committee on Alcoholism announced an upcoming 'A-Day' under the non-uplifting slogan: 'You can drink — help the alcoholic who can't.' ('Can't'?) The International Court of Justice at The Hague ruled in favor of Britain in the Corfu Channel dispute with Albania. At the UN, Soviet Foreign Minister Andrei Gromyko denounced the newly formed NATO alliance as a tool for aggression against the USSR. The rising Chinese Communists, under a man then known to Western readership as Mao Tze-Tung, announced a limited willingness to bargain with the still-existing Chinese government in a city then known to the outside world as 'Peiping.'

All this was unknown to me as I nuzzled my mother's breast for the first time, and would certainly have happened in just the same way if I had not been born at all, or even conceived. One of the newspaper astrologists for that day addressed those whose birthday it was:

<blockquote>There are powerful rays from the planet Mars, the war god, in your horoscope for your coming year, and this always means a chance to battle if you want to take it up. Try to avoid such disturbances where women relatives or friends are concerned, because the outlook for victory upon your part in such circumstances is rather dark. I

The American public is therefore much better prepared than has been thought for investigating the origin of the notion of space.

His parted lips were lips which spoke, not of love, but of millions of miles; those were eyes which habitually gazed, not into the depths of other eyes, but into other worlds. Within his temples dwelt thoughts, not of woman's looks, but of stellar aspects and the configuration of constellations.

The reappearance of the crescent moon after the new moon; the return of the Sun after a total eclipse, the rising of the Sun in the morning after its troublesome absence at night were noted by people around the world; these phenomena spoke to our ancestors of the possibility of surviving death. Up there in the skies was also a metaphor of immortality.

Any patch of sunlight in a wood will show you something about the sun which you could never get from reading books on astronomy. These pure and spontaneous pleasures are ‘patches of Godlight’ in the woods of our experience.
