Carl Sagan’s quotes

Carl was not just the guy who made science cool for the public and had a couple of good ideas about the future of humanity. He was also an eloquent, persuasive and quotable speaker. He knew how to make the complex simple. He knew how to shrink a complex yet important message into a 10 to 20-word easily memorable “package”. That’s why his ideas will be passed on from generation to generation and remembered forever. Take a look at our collection of top Carl Sagan’s inspirational quotes with an explanation for each:

“We are made of star stuff. We are a way for the cosmos to know itself.”

In the cores of stars, thermonuclear fusion at extreme temperatures and pressure creates heavier natural elements, most notably carbon(6), nitrogen(7), oxygen(8), all the way up to iron(26). And all life is based upon this star stuff. Including you.

“Imagination will often carry us to worlds that never were. But without it we go nowhere.”

Without sci-fi, without vivid imagination, how would you encourage scientists and the general public to support space research?

“The sky calls to us. if we do not destroy ourselves, we will one day venture to the stars.”

 Throughout all our history, our need to explore has driven us to places never seen before. Without it we would not be alive today. Yet the surface of Earth is known to us already, the next level is space. We have to go there anyway because the Sun will otherwise become too hot and kill us in approx. 500 million years (swallowing Earth completely a couple of billions years later).

“Every kid starts out as a natural-born scientist, and then we beat it out of them. A few trickle through the system with their wonder and enthusiasm for science intact.”

A critique of the education system from 1996 – the year Carl died. It is still valid today, although we are moving slowly in the right direction now (take all the E-learning websites and science experiments on YouTube). If only Carl could see this! At least his words live on and serve us as a reality check.

More from Carl Sagan

The famous youtuber melodysheep took Carl Sagan’s quotes and compiled them into a song made of star stuff.

Listen to the symphony of science and see if it makes you feel more connected with all the other people on Earth and the cosmos itself.

Rest in peace, Carl Sagan (1934-1996). Long live Stephen Hawking!
