We've arranged a civilization in which most crucial elements profoundly depend on science and technology.

“The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”
Carl Sagan
“In the way that scepticism is sometimes applied to issues of public concern, there is a tendency to belittle, to condescend, to ignore the fact that, deluded or not, supporters of superstition and pseudoscience are human beings with real feelings, who, like the sceptics, are trying to figure out how the world works and what our role in it might be. Their motives are in many cases consonant with science. If their culture has not given them all the tools they need to pursue this great quest, let us temper our criticism with kindness. None of us comes fully equipped.”
Carl Sagan
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Carl Sagan
Extinction is the rule. Survival is the exception.
Carl Sagan
Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.
Carl Sagan
Absence of evidence is not evidence of absence.
