A prominent architect was in charge of designing the city hall. When all the construction was finished, city councilors went to the city hall to check. The councilors who looked around the building ordered that more columns be built, saying that the number of pillars seemed to be few, compared with the area of the lobby. The architect tried to persuade the councilors, saying that he devoted himself to the design so that there were no problems supporting the ceiling, but the councilors did not agree. Eventually, four more columns were set up in the lobby.
A long time passed since then. One day, an officer inspected the city hall building and discovered something surprising. There were gaps at the top of some pillars, so they did not actually support the ceiling. Those were useless pillars put up additionally at the stubborn request of the councilors in the past.
This is the story of the Windsor Guildhall in the U.K. It shows that the claims of those who did not trust the architect were merely stubbornness, and Windsor Guildhall still has columns that do not reach the ceiling.
If we assert only our thoughts, our view narrows and our ears close, which causes unnecessary conflict and efforts. When we come across different opinions, let us examine to see if I am setting up any useless pillars in my mind.
