More quotes by Carl Sagan
We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan
Indeed the reasoned criticism of a prevailing belief is a service to the proponents of that belief if they are incapable of defending it, they are well advised to abandon it. This self-questioning and error-correcting aspect of the scientific method is its most striking property.
Carl Sagan
The politicians and the religious leaders and the weapons scientists have been at it for a long time and they've made a thorough mess of it. I mean, we're in deep trouble.
Carl Sagan
Our ancestors lived out of doors. They were as familiar with the night sky as most of us are with our favorite television programs.
Carl Sagan
We all have a thirst for wonder. It's a deeply human quality. Science and religion are both bound up with it. What I'm saying is, you don't have to make stories up, you don't have to exaggerate. There's wonder and awe enough in the real world. Nature's a lot better at inventing wonders than we are.
Carl Sagan
Except for children (who don't know enough not to ask the important questions), few of us spendtime wondering why nature is the way it is . . .
Carl Sagan
While our behavior is still significantly controlled by our genetic inheritance, we have, through our brains, a much richer opportunity to blaze new behavioral and cultural pathways on short timescales.
Carl Sagan
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.
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
In a complex universe, in a society undergoing unprecedented change, how can we find the truth if we are not willing to question everything and to give a fair hearing to everything?
Carl Sagan
The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.
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
The notion that science and spirituality are somehow mutually exclusive does a disservice to both.
Carl Sagan
We are the universe experiencing itself.
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
There is a report that says that kids who watch violent TV programs tend to be more violent when they grow up. But did the TV cause the violence, or do violent children preferentially enjoy watching violent programs?
Carl Sagan
Those who seek power at any price detect a societal weakness, a fear that they can ride into office.
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.
