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 am ever more intrigued by the correspondence between mathematics and physical facts. The adaptability of mathematics to the description of physical phenomena is uncanny.
In nature, when you conduct science, it is the natural world that is the ultimate decider in what is true and what is not.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
Medicine is of all the Arts the most noble; but, owing to the ignorance of those who practice it, and of those who, inconsiderately, form a judgment of them, it is at present behind all the arts.
Science fiction [is] the kind of writing that prepares us for the necessary mutations brought about in society from an ever changing technological world and as a result. The mainstream hasn’t excluded SF; the mainstream has excluded itself. No one told Jules Verne he was a science fiction writer, but he invented the 20th century.
What's been gratifying is to live long enough to see molecular biology and evolutionary biology growing toward each other and uniting in research efforts.
