I don't know
The underlying theme that we will see in my opinion is how hard it is for most people to admit that they are wrong. What happens to our consciousness is that we have such a fear of being wrong that we will only perceive and remember those facts which suppport our own personal opinion as being "right". Anything that goes against our view gets labeled to trick ourselves into thinking we understand it. Thus we will have "experts" on all different sides blatantly distorting reality to reinforce and protect their own beliefs. Most of us are just too weak to withstand the feelings of disorientaion and insecurity that natually arise when our core beliefs are under attack. Sadly, this leaves most of us incapable of growing or learning because the only way that happens is by saying: I don't know.
The smartest thing I have ever said is: I don't know. That's what allowed me to begin practicing tai chi almost a decade ago. That is what led me to be able to play the didjeridoo.
