thoughtfully disagree are the greatest teachers, far better than a professor assigned to stand in front of a board and lecture at you. The knowledge I acquire usually leads to principles that I develop and refine for similar cases that arise in the future. In some cases in which the subjects are just too complex for me to understand in the time required, I will turn over the decision making to knowledgeable others who are more believable than me, but I still want to listen in on their thoughtful disagreement.
