This is an interesting perspective. I suppose on some level I recognize the weakness in the person who cannot and will not admit he or she is wrong notwithstanding evidence—overwhelming evidence—to the contrary. I do not even like using the word "evidence" here because it implies some wiggle room for doubt or that they could be right, as remote as that might be.

They are lying and will not give an admission. That is what we are dealing with here. So I posit a question to you: What is distinguishable between a "fragile ego" and a "pathological liar"? At what point do we call this a disease or even "evil" for as Paul Gerhardt once said, " When a man lies, he murders some part of the world."

So what is the distinction?
