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.

More quotes by Carl Sagan
The evidence, so far at least and laws of Nature aside, does not require a Designer. Maybe there is one hiding, maddeningly unwilling to be revealed.
Carl Sagan
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.
Carl Sagan
You're capable of such beautiful dreams and such horrible nightmares.
Carl Sagan
Much of human history can, I think, be described as a gradual and sometimes painful liberation from provincialism, the emerging awareness that there is more to the world than was generally believed by our ancestors.
Carl Sagan
We are the universe experiencing itself.
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
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Carl Sagan
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
Carl Sagan
The cure for a fallacious argument is a better argument, not the suppression of ideas.
Carl Sagan
We are star stuff which has taken its destiny into its own hands.
Carl Sagan
That kind of skeptical, questioning, don't accept what authority tells you attitude of science - is also nearly identical to the attitude of mind necessary for a functioning democracy. Science and democracy have very consonant values and approaches, and I don't think you can have one without the other.
Carl Sagan
The Hindu religion is the only of the World's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.
Carl Sagan
In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!
Carl Sagan
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
Carl Sagan
A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.
Carl Sagan
The vast distances that separate the stars are providential. Beings and worlds are quarantined from one another. The quarantine is lifted only for those with sufficient self-knowledge and judgment to have safely traveled from star to star.
Carl Sagan
Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?
Carl Sagan
