Science is a way to not fool ourselves.
Carl SaganRead
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
Interpretation
What this quote means
The quote emphasizes the importance of open-mindedness and the ability to change one's views based on new evidence, contrasting this with the rigidity often found in politics and religion.
Carl Sagan highlights the scientific method's unique capacity for self-correction, where scientists are willing to admit when they are wrong and alter their beliefs in light of new arguments or data. He suggests that while this change is more common in science, it is rare in the realms of politics and religion, which can be resistant to change despite evidence. This observation underscores the importance of humility and adaptability in the pursuit of truth, acknowledging that change can be difficult but is often essential for growth.

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.

I thought scientists were going to find out exactly how everything worked, and then make it work better. I fully expected that by the time I was twenty-one, some scientist, maybe my brother, would have taken a color photograph of God Almighty—and sold it to Popular Mechanics magazine. Scientific truth was going to make us so happy and comfortable. What actually happened when I was twenty-one was that we dropped scientific truth on Hiroshima.
