We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going.

This quote emphasizes our biological origins while recognizing our human pursuits for meaning.
Carl Sagan reflects on the essence of human existence by suggesting that we are temporary vessels of genetic material, yet this biological fact does not diminish our humanity or our striving for goodness, truth, and beauty. He warns against disregarding our origins as we seek to understand our future, highlighting the importance of acknowledging our roots in guiding our journey forward.

The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.
We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future.
I give them experiments and they respond with speeches.
The facts will eventually test all our theories, and they form, after all, the only impartial jury to which we can appeal.
