Science is a way to not fool ourselves.

[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.
Interpretation
What this quote means
Criticism of ideas is necessary for scientific progress, and one must learn to discard ineffective ideas in favor of better ones.
In this quote, Carl Sagan emphasizes the importance of accepting criticism in the realm of science. He points out that when an idea fails to hold up, it is essential to let go of that idea and focus energy on developing new ideas that can provide better explanations for data. Embracing valid criticism should be seen as a constructive act that aids in the advancement of knowledge rather than a personal affront.

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.
