I think that this idea could serve in plenty of different arenas. The scientist might restrict his categorical annunciations to the field of his inquiry rather than believe his microscope gives him insight into fields in which he has no expertise. The priest might realize that he would be silly to tell the scientist what he observes in the lab is untrue. If every profession looked at itself a bit more humbly and realized that its vision of the world is not complete, it is likely that there would be far less strife and far more brotherhood in the world today.
Amazingly, this isn't a new thought. Plato dealt with such thoughts in his own time. In the Gorgias he was dealing with the Sophists who knew nothing about the subject matter they spoke yet still won arguments through subtle persuasion. In the Euthyphro he makes a passing comment about those who assume their proficiency in one area gives them the right to speak in all arenas. His conclusion in the Republic is to take everyone over the age of ten in a city, whack them, and then let Philosopher-Kings rule.
This illustrates my point succinctly. There is an inherent hubris in mankind that divides the world into the "us"and "them." We justify the "us" and demonize the "them" in, what I truly believe, is an attempt to establish a righteousness of our own. We want so desperately to be good and right that the only way we can do this is by cutting everyone else to pieces.
I think Paul's solution is far better than Plato's. We need to realize that each one of us needs the other in order for the world to run correctly. Just one person who doesn't contribute their unique part robs the world of its potential. This humility (which I believe finds its consummation in the Gospel) doesn't take anything away from us or belittle our contributions. Rather it establishes them and confirms us in the work that we are uniquely able to do without having to steal meaningfulness from somebody else's area of expertise.
