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.

My long-time view about Christianity is that it represents an amalgam of two seemingly immiscible parts-the religion of Jesus and the religion of Paul. Thomas Jefferson attempted to excise the Pauline parts of the New Testament. There wasn't much left when he was done, but it was an inspiring document.

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.

There is never only ONE of anything in nature.

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.

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

Our passion for learning ... is our tool for survival.

The Bill of Rights decoupled religion from the state, in part because so many religions were steeped in an absolutist frame of mind - each convinced that it alone had a monopoly on the truth and therefore eager for the state to impose this truth on others.
Carl Sagan
Image
But nature is always more subtle, more intricate, more elegant than what we are able to imagine.
Carl Sagan
Image
Extraordinary observations require extraordinary evidence to make them believable.
Carl Sagan
Image
For all our failings, despite our limitations and fallibilities, we humans are capable of greatness.
Carl Sagan
Image
We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Carl Sagan

Imagine we could accelerate continuously at 1 g-what we're comfortable with on good old terra firma-to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars.

The universe is a pretty big place. If it's just us, seems like an awful waste of space.

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.

When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.
Carl Sagan

We are, each of us, a multitude. Within us is a little universe.
Carl Sagan

For all its material advantages, the sedentary life has left us edgy, unfulfilled, even after 400 generations in villages and cities, we haven't forgotten: The open road still softly calls like a nearly forgotten song of childhood.

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.

In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
