Science is a way to not fool ourselves.
Carl SaganRead
All of us cherish our beliefs. They are, to a degree, self-defining. When someone comes along who challenges our belief system as insufficiently well-based - or who, like Socrates, merely asks embarrassing questions that we haven't thought of, or demonstrates that we've swept key underlying assumptions under the rug - it becomes much more than a search for knowledge. It feels like a personal assault.
Interpretation
Challenging beliefs can feel threatening because they are closely tied to our identity.
In this quote, Carl Sagan discusses the deep connection between our beliefs and our sense of self. When our beliefs are questioned, particularly in ways that reveal flaws or overlooked assumptions, it can provoke a defensive reaction that feels personal rather than a simple intellectual inquiry.
In practice
In a discussion about personal growth, one could use this quote to emphasize the importance of questioning one's beliefs.
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.
It is a terrible thing to be happy! How pleased we are with it! How all-sufficient we think it! How, being in possession of the false aim of life, happiness, we forget the true aim, duty!
Even victors are by victories undone.
It especially annoys me when racists are accused of 'discrimination.' The ability to discriminate is a precious faculty; by judging all members on one 'race' to be the same, the racist precisely shows himself incapable of discrimination.
This so gnawed at him on some nights that he lay awake wondering just how many unknown and similarly inconsequential accidents and bits of happenstance were at this moment occurring or failing to occur in order to ensure he took his next breath, and the next.
Every time I see an adult on a bicycle, I no longer despair for the future of the human race.
The world is well supplied with spiders whose male ancestors died after mating. The world is bereft of spiders whose would-be ancestors never mated in the first place.
