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 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 significant chemicals of living tissue are rickety and unstable, which is exactly what is needed for life.
The image of the scientist who puts the pursuit of truth before anything else has been shattered and replaced by a man on the make or a quasi-religious enthusiast who wants to prove his case at any cost. Science is becoming the tool of campaigning warfare, in which truth is the first casualty.
I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme.
It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.

NASA has spin-offs, and it's a huge and very impressive list, including accurate and affordable LASIK eye surgery.
