He points in the beginning what Leo Tolstoy said
"The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already.”
I didn't knew somebody wise has already made statement that is exactly what I have been thinking about. No doubt I am now losing extra wisdom tooth.
I used to and on many occasion still come across people who say "I know" but when they say that they are not careful enough what that might lead to when they say "I know". It is good to know and knowing is everything, but listening to others is also equally important. With the attitude to not listen or ignore with over confidence or persuade on a belief that you know it right and better than the other person will shun your ability to judge and make better decision. If a person chooses not to listen and continues to flap his wings of his righteousness would ultimately become outdated of what is right (for himself or for his fellows).
Ignorance is not bliss, Always be open to listen to others.
I used to call this thoughts eclipsing thinking, because such an attitude limits your thinking, devouring the person from the path of progress or may totally lead to misery.
Recalling from the book I read on neuroscience of human brain. The neo limbic brain is responsible for day to day things, usual habits and it acts like an autopilot mode. Which means whenever somebody ask for a solution the new limbic brain will give the quickest available solution but that would stop the person to innovate, no new thinking or solution from a varied point of view. That is when person should put exquisite effort to think differently and be open in accepting various possibilities. Coming up with a solution to a problem from different point of view will let the person innovate and that is when he/she make use of prefrontal brain.
Prefrontal brain is responsible for creative and out of the box thinking.
All it just requires a degree of scientific thinking an attitude of listening to what others have to say.
