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
Frederick Douglas taught that literacy is the path from slavery to freedom. There are many kinds of slavery and many kinds of freedom, but reading is still the path.
Carl Sagan
The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses.
Carl Sagan
What's the harm of a little mystification? It sure beats boring statistical analyses.
Carl Sagan
We are made of star-stuff. Our bodies are made of star-stuff. There are pieces of star within us all.
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
Except for fools and madmen, everyone knows that nuclear war would he an unprecedented human catastrophe.
Carl Sagan
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
Carl Sagan
Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.
Carl Sagan
If some good evidence for life after death were announced, I'd be eager to examine it but it would have to be real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say, than the comforting fantasy.
Carl Sagan
I don't want to believe. I want to know.
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
If we teach only the findings and products of science - no matter how useful and even inspiring they may be - without communicating its critical method, how can the average person possibly distinguish science from pseudoscience?
Carl Sagan
We are prodding, challenging, seeking contradictions or small, persistent residual errors, proposing alternative explanations, encouraging heresy. We give our highest rewards to those who convincingly disprove established beliefs.
Carl Sagan
Those who seek power at any price detect a societal weakness, a fear that they can ride into office.
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
If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?
Carl Sagan
Extraordinary claim requires extraordinary proof.
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
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
Don't judge everyone else by your own limited experience.
Carl Sagan
