More quotes by Carl Sagan
A still more glorious dawn awaits / not a sunrise, but a galaxy-rise / a morning filled with 400 billion suns / the rising of the milky way
Carl Sagan
The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos.
Carl Sagan
We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.
Carl Sagan
It does no harm to the romance of the sunset to know a little bit about it.
Carl Sagan
Those who seek power at any price detect a societal weakness, a fear that they can ride into office.
Carl Sagan
You mustn't think of the Universe as a wilderness. It hasn't been that for billions of years, he said. Think of it more as... ..cultivated.
Carl Sagan
The Big Bang is our modern scientific creation myth. It comes from the same human need to solve the cosmological riddle [Where did the universe come from?]
Carl Sagan
Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
Carl Sagan
A millennium before Europeans were willing to divest themselves of the Biblical idea that the world was a few thousand years old, the Mayans were thinking of millions and the Hindus billions.
Carl Sagan
We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?
Carl Sagan
I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.
Carl Sagan
Preserve and cherish the pale blue dot, the only home we've ever known.
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
Carl Sagan
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
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
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
Carl Sagan
And you are made of a hundred trillion cells. We are, each of us, a multitude.
Carl Sagan
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
Carl Sagan
The dumbing down of America is evident in the slow decay of substantive content, a kind of celebration of ignorance.
Carl Sagan
