More quotes by Carl Sagan
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
Carl Sagan
At the extremes it is difficult to distinguish pseudoscience from rigid, doctrinaire religion.
Carl Sagan
These days there seems to be nowhere left to explore, at least on the land area of the Earth. Victims of their very success, the explorers now pretty much stay home.
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Carl Sagan
Our loyalties are to the species and the planet. We speak for Earth.
Carl Sagan
Science is not perfect. It's often misused it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.
Carl Sagan
The wind whips through the canyons of the American Southwest, and there is no one to hear it but us - a reminder of the 40,000 generations of thinking men and women who preceded us, about whom we know almost nothing, upon whom our civilization is based.
Carl Sagan
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble.
Carl Sagan
We live at a moment when our relationships to each other, and to all other beings with whom we share this planet, are up for grabs.
Carl Sagan
By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.
Carl Sagan
Science is more than a body of knowledge. It's a way of thinking: a way of skeptically interrogating the universe.
Carl Sagan
With insufficient data it is easy to go wrong.
Carl Sagan
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge it has no in the endeavor of science. We do not know in advance who will discover fundamental insights.
Carl Sagan
We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.
Carl Sagan
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
Carl Sagan
Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.
Carl Sagan
Extraordinary claims demand extraordinary evidence
Carl Sagan
In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.
Carl Sagan
Who are we, if not measured by our impact on others?
Carl Sagan
