We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.

Time spent with children is time well spent. Their little minds are not constrained by 'reality' or focused upon goals. Anything and everything is possible. Imagination will often carry us to worlds that never were. But without it we go nowhere.

Carl Sagan

Children, Reality, Imagination

Growing Up, Answers, Firsts

4 Copy quote
When a honeybee dies it releases a death pheromone, a characteristic odour that signals the survivors to remove it from the hive. The corpse is promptly pushed and tugged out of the hive. The death pheromone is oleic acid. What happens if a live bee is dabbed with a drop of oleic acid? Then no matter how strapping and vigourous it might be, it is carried kicking and screaming out of the hive.

Carl Sagan

Science, Survivor, Kicking

4 Copy quote
For myself, I like a universe that, includes much that is unknown and, at the same time, much that is knowable. A universe in which everything is known would be static and dull, as boring as the heaven of some weak-minded theologians. A universe that is unknowable is no fit place for a thinking being. The ideal universe for us is one very much like the universe we inhabit. And I would guess that this is not really much of a coincidence.

Carl Sagan

Knowledge, Science, Thinking

Those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.

Wish, Prejudice, Cosmos

8 Copy quote
My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence is provided by such a God. We would be unappreciative of that gift if we suppressed our passion to explore the universe and ourselves.

Carl Sagan

God, Passion, Religion

The usual rejoinder to someone who says 'They laughed at Columbus, they laughed at Galileo' is to say 'But they also laughed at Bozo the Clown'.

Carl Sagan

Otherwise we don't run the government the government runs us

Carl Sagan

Running, Government

Carl Sagan, Tom Head (2006). “Conversations with Carl Sagan”, p.143, Univ. Press of Mississippi

4 Copy quote
Many statements about God are confidently made by theologians on grounds that today at least sound specious. Thomas Aquinas claimed to prove that God cannot make another God, or commit suicide, or make a man without a soul, or even make a triangle whose interior angles do not equal 180 degrees. But Bolyai and Lobachevsky were able to accomplish this last feat (on a curved surface) in the nineteenth century, and they were not even approximately gods.

Carl Sagan

Suicide, Atheist, Men

If there is life, then I believe we should do nothing to disturb that life.
Mars then, belongs to the Martians, even if they are microbes.

4 Copy quote
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.

Virtually every major technological advance in the history of the human species - back to the invention of stone tools and the domestication of fire - has been ethically ambiguous.

Carl Sagan

Atheist, Fire, Religion

For a long time the human instinct to understand was thwarted by facile religious explanations.

Carl Sagan

Religious, Time, Long

Carl Sagan (2011). “Cosmos”, p.194, Ballantine Books

4 Copy quote
The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.

Carl Sagan

Thinking, Errors, Light

Carl Sagan (2011). “Cosmos”, p.293, Ballantine Books

Man is the matter of the cosmos, contemplating itself.

Carl Sagan

Men, Cosmos, Matter

4 Copy quote
These are all cases of proved or presumptive baloney. A deception arises, sometimes innocently but collaboratively, sometimes with cynical premeditation. Usually the victim is caught up in a powerful emotion -- wonder, fear, greed, grief. Credulous acceptance of baloney can cost you money; that's what P. T. Barnum meant when he said, 'There's a sucker born every minute.' But it can be much more dangerous than that, and when governments and societies lose the capacity for critical thinking, the results can be catastrophic -- however sympathetic we may be to those who have bought the baloney.

Carl Sagan

Powerful, Grief, Acceptance

Carl Sagan (2011). “The Demon-Haunted World: Science as a Candle in the Dark”, p.209, Ballantine Books

4 Copy quote
The impediment to scientific thinking is not, I think, the difficulty of the subject. Complex intellectual feats have been mainstays even of oppressed cultures. Shamans, magicians and theologians are highly skilled in their intricate and arcane arts. No, the impediment is political and hierarchical.

Carl Sagan

Art, Thinking, Political

6 Copy quote
These days there seems to be nowhere left to explore, at least on the land area of the Earth. Victims of their very success, the explorers now pretty much stay home.

Carl Sagan

Home, Land, Earth

Carl Sagan, Ann Druyan (2011). “Pale Blue Dot: A Vision of the Human Future in Space”, p.17, Ballantine Books

4 Copy quote
Because men, compared to male chimps, have such relatively small testicles (large testicles indicate a species where many males mate, one after the other, with the same female), we might guess that promiscuous societies were uncommon in the immediate human past.

Carl Sagan

Past, Men, Males
