PARASITOLOGY
From Carl Sagan in reference to the first photograph of Earth from deep
space:
A Photo taken by Voyager
on the way out of the solar system
"We succeeded in taking that picture [from deep space], and, if you look
at it, you see a dot. That's here. That's home. That's us. On it,
everyone you ever heard of, every human being who ever lived, lived out
their lives. The aggregate of all our joys and sufferings, thousands of
confident religions, ideologies and economic doctrines, every hunter and
forager, every hero and coward, every creator and destroyer of
civilizations, every king and peasant, every young couple in love, every
hopeful child, every mother and father, every 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 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 in 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 the dot on scarcely distinguishable inhabitants of some other
corner of the dot. 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. It is up to us.
It's been said that astronomy is a humbling, and I might add, a
character-building experience. To my mind, 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 and compassionately with one another and to preserve and cherish
that pale blue dot, the only home we've ever known."
Another image that is amazing and really brings home the point of
where we are on the earth is this: Earth
