More quotes by Carl Sagan
I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
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
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
If chimpanzees have consciousness, if they are capable of abstractions, do they not have what until now has been described as 'human rights'? How smart does a chimp have to be before killing him constitutes murder?
Carl Sagan
Preserve and cherish the pale blue dot, the only home we've ever known.
Carl Sagan
If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.
Carl Sagan
We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
Carl Sagan
Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.
Carl Sagan
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
Every thinking person fears nuclear war, and every technological state plans for it. Everyone knows it is madness, and every nation has an excuse
Carl Sagan
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
There are lots of ways to communicate what we know, but few ways to communicate what we feel. Music is one way to communicate emotions.
Carl Sagan
Cutting off fundamental, curiosity-driven science is like eating the seed corn. We may have a little more to eat next winter but what will we plant so we and our children will have enough to get through the winters to come?
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
For all our failings, despite our limitations and fallibilities, we humans are capable of greatness.
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
Across the sea of space, the stars are other suns.
Carl Sagan
If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
Carl Sagan
What an astonishing thing a book is.
Carl Sagan
Somewhere, something incredible is waiting to be known.
Carl Sagan
