More quotes by Carl Sagan
Recent research shows that many children without enough to eat wind up with diminished capacity to understand and learn (“cognitive impairment” ). Children don't have to be starving for this to happen. Even mild undernourishment — the kind most common among poor people in America — can do it.
Carl Sagan
In Mozambique, the story goes, monkeys do not talk, because they know if they utter even a single word some man will come and put them to work.
Carl Sagan
Science is not perfect. It's often misused it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.
Carl Sagan
But nature is always more subtle, more intricate, more elegant than what we are able to imagine.
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
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 Universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The Universe belongs to those who, at least to some degree, have figured it out.
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
Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.
Carl Sagan
We can't help it. Life looks for life.
Carl Sagan
Man is a transitional animal. He is not the climax of creation
Carl Sagan
If we say that God has always been, why not save a step and conclude that the universe has always been?
Carl Sagan
It is said that men may not be the dreams of the god, but rather that the gods are the dreams of men.
Carl Sagan
By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.
Carl Sagan
Any civilization that doesn't develop space travel dies.
Carl Sagan
The Cosmos is all that is or ever was or ever will be.
Carl Sagan
When you realize that no one really knows what they are doing and that everyone is doing the best they can according to their own level of consciousness, life gets a lot easier. Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
What's the harm of a little mystification? It sure beats boring statistical analyses.
Carl Sagan
Not all birds can fly. What separates the flyers from the walkers is the ability to take off.
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
