I find it incredibly interesting how hard the mind works to prevent rational thought when it suits it's purpose. It seems capable of any level of cognitive hide and seek, in order to escape rationality/believe myths to be history.
This how the human mind works, not just with religion but also how we choose to remember events, conversations and arguments. The mind is a tool that works hard to keep an emotional equilibrium and balance in our individual world.
The mind is capable of great treachery. To be totally rational takes many years of training. Total rationality can take us out of our comfort zone. So in order to enjoy our lives we have to develop and employ the art of compromise.
