Anecdote: You need heart surgery NOW. If you don't have it within the next half hour you are going to die. You are at a camp in the wilderness of Alaska a good six hour hike from the nearest hospital. In the camp with you are about twenty five people. In that group there are 5 people who claim to know what is wrong with you and claim to be able to cut open your chest and fix the problem. The problem is that not one of them has been trained to do so. Each of them have their claim as to why they are certain they can perform the procedure. Two of them say they've seen it done dozens of times on TV. One of them says he has read The Encyclopedia of Medicine. The other two claim God speaks to them and told them that they could do it and that they will listen to the still small voice of God within them for instructions throughout the procedure. Another man laughs at them. He calls them all idiots. He says, "You listen to these guys and they'll kill you. But I can save you. I am one of the best heart surgeons in the world- not to mention I am also the best looking!" But he really is a fantastic heart surgeon- even if he is arrogant. Both the first group and the last man are arrogant. But which one can really save your life? Which ones stand the best chance of butchering you? Arrogance by itself is not good- but it becomes DEADLY when coupled with ignorance.
