Lately I have seen numerous examples of seemingly intelligent people seeking to cling to biases, preconceived beliefs, and to ignore or shout down what would more likely be the truth. In a state of cognitive dissonance, they become agitated.
As a person who has sought, searched for, closer and closer approximations to truth, it is astounding to watch. It is fascinating, and yet disturbing. It is almost as if the particular bias is a religious tenet of some high and noble, but yet unknown religion. The mythical altar is strewn with protections of the sacred tenets.
I ask you, please, if you have some belief or other that you protect from all questions and alternative ideas, go for it - dare to consider it from other perspectives. If it is true, it will hold up to any investigation. If it is not true or partially true, it is best to know. Dare to question. Step out of any box that restrains. Be all you can be. Be free.
