THE SACRIFICE OF UNDERSTANDING

Whether it’s religion,  governing,  corporate life,  science,  academia, war or any other area where people have their livelihood at stake, truth and understanding can often be shunted aside.  

The need to protect what one has is great and it can be a noble thing. But, when you are willing to sacrifice understanding true evidence that comes before you, in the name of protecting your little bit of turf, then something dangerous can happen.

People can rationalize any falsehood and avoid any truth when they have great fear.
