It’s amazing how many ideas/beliefs/books/theories/dogmas/opinions are based upon facts that are out-of-date or that have been replaced or disproven. There is far too much permanence of ideas. Most ideas are so firmly established that even when an important building block is removed, the idea still stands.
This happens in every aspect of life. As a person continues with the entrenched narrative, it’s easy to not notice that the fact set has become different.
How many Bible scholars realize that it is no longer believed that the gospels were written in Hebrew/Aramaic? How many arguments and assumptions still exist that were invented based upon this belief?
How many Obstetricians in 1981 believed that alcohol could stop preterm labor? How many believe that magnesium does today?
We must deconstruct every belief carefully and analyze its core components; we must analyze every card that makes up a house of cards. When two people firmly believe opposite things, one or both of them are likely wrong about something that they don’t even realize they are wrong about, some obscure fact that long ago helped establish a false narrative.
It takes courage to deconstruct your core beliefs.
