Science is a way to not fool ourselves.
Carl SaganRead
One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.
Interpretation
Science thrives on self-criticism and testing ideas against reality, distinguishing itself from pseudoscience.
In this quote, Carl Sagan emphasizes the iterative nature of scientific inquiry, where self-criticism and external testing of ideas are fundamental. He warns against the dangers of pseudoscience and superstition that arise when we allow our hopes to cloud our judgment, highlighting that true scientific progress relies on rigorous examination and skepticism.
In practice

Science is a way to not fool ourselves.
In more than one respect, the exploring of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history.
How smart does a chimpanzee have to be before killing him constitutes murder?
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.
The fact that all Mathematics is Symbolic Logic is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists of the analysis of Symbolic Logic itself.
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
The universe is almost like a huge magic trick and scientists are trying to figure out how it does what it does.
When I test I never go right to the limit. Only because when you are below the limit you can go at the same speed all day, and that's the only way you can be absolutely sure about what you are testing.
We should begin at the very root from which we spring, we should effect a radical reform in the character of the food.
If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.
