卡爾薩根的文章

“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.

那就是這裡，那就是我們的家，那就是我們，在這點上，每一個你愛的人。每一個你認識的人，每一個你聽過的人，每一個已經過完一生的人。這裡聚集了一切的歡喜與苦難、上千種的宗教、意識形態和經濟學說，每一個狩獵者和採集者，每一個英雄和懦夫、各種文化的重造者與毀滅者；每一個國王與侍臣，每一個相戀中的年輕伴侶每一個母親與父親、充滿希望的兒童、發明家和探險家、每一個品行端正的老師、每一個腐敗的政客、每一個超級巨星、每一個至高無上的領袖、每一個人類史上的聖人與罪人、通通住在這裡、都活在這個沐浴於陽光中的小塵埃。

The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”
