I'll probably read it, given that you have started well.

As fond as I am of the RM, I would hate to see it be "king of the hill" in college teaching.

In fact, I think of "king of the hill" type thinking as closed minded, whether the topic is data modeling, physics, interpretation of Shakespeare, or political science. I deplore those who try to establish a hegemony of ideas within the university. And I see much too much of that in today's universities.

As for me, I regard the RM as "king of one of the hills, and there are alot of other hills".

I think that the truth that will eventually out is this: there is a class of problems for which the RM is a useful framework for disciplined thinking, and there is a class of problems for which it is not.
