Ron, I really liked your concept that "knowledge is a precious object that requires control and careful dissemination."
This recalls some academic work I have done using the qualitative methodology autoethnography. I have done some writing that traces my worldview as transitioning from positivism to constructivism. I used to think that knowledge was that precious je ne sais quoi, that which is beyond interpretation and evident to people in similar ways if they try hard enough to gain it.
Looking back at that now, I am wondering if this is just not another way of protecting the views and interests of the majority, in whatever community or organization or group we are considering. In this case, knowledge, understood in only one established way, maintains the status quo.
