Through curiosity and probable skepticism, he not only worked out the basic rules for matter and energy in the universe — he also realized that the force causing objects to fall was the same as the force causing celestial objects to orbit around each other (thus discovering the modern theory of gravity).
He was also known for having a big ego and being a little arrogant with those he considered beneath his intellect — but even Newton had enough humility to recognize that he wasn’t doing it alone.
This makes them more receptive to information, better listeners and learners.
Skepticism means you always demand evidence and don’t simply accept what others tell you.
This is closely connected to curiosity — if you’re arrogant and think you know everything already, then you have no reason to be curious.
But a humble person always recognizes the limitations and gaps in their knowledge.
For example, at one stage in the classic RPG , your character has the option to serve as a juror on another character’s trial.
In order to save the innocent man, you have to talk to people throughout the town and, using a combination of empathy and skepticism, figure out what really happened.
Enlightenment thinkers understandably rejected traditional thinking, holding it responsible for all this violence and injustice.
But still, the Enlightenment sometimes went too far in the opposite direction.
