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
m o r a l s , e ve r y c o r r u p t p o l i t i c i a n , e ve r y
"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 Earth is a very small stage in a vast cosmic
arena. 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. 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.


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
t i ny w o r l d . To m e , i t u n d e r s c o r e s o u r
responsibility to deal more kindly with one
another, and to preserve and cherish the pale
blue dot, the only home we've ever known.

Carl Sagen May 11th, 1996
