Pride is the killer. It blinds those in it’s grip to the possibility that they may be wrong about anything. They are totalitarians. They assume total knowledge. Pride is why satan fell from heaven where he had been the most beautiful of the angels. It is the root of much foolishness, greed and rebellion today.
The humble person is intellectually honest, open to evidence and well reasoned arguments. One poor wise man telling the truth can save a kingdom, even if his work is forgotten.
