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.

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.
I would still very much love to change the world, and there are three or four neurological diseases that I've got a personal grudge against. I wouldn't mind mopping them up in one amazing experiment to come out of my lab, and I certainly wouldn't mind transforming hundreds of thousands of people's lives overnight with some discovery.
The scientist who recognizes God knows only the God of Newton. To him the God imagined by Laplace and Comte is wholly inadequate. He feels that God is in nature, that the orderly ways in which nature works are themselves the manifestations of God's will and purpose. Its laws are his orderly way of working.
I believe there are no questions that science can't answer about a physical universe.
Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.
The imposing edifice of science provides a challenging view of what can be achieved by the accumulation of many small efforts in a steady objective and dedicated search for truth.
Science has a culture that is inherently cautious and that is normally not a bad thing. You could even say conservative, because of the peer review process and because the scientific method prizes uncertainty and penalises anyone who goes out on any sort of a limb that is not held in place by abundant and well-documented evidence.
