All graduate programs weed out people because not everyone can do it--"it" being history, or English, or physics, or what have you. That is not the point.
The point is that history is the queen of all academic disciplines. That is the point.
Wait...since this a rooster-measuring contest, wouldn't the winner be King?
As to the original post, this attitude more often manifests in the
students of those other disciplines. I taught a few courses in "Intro to Communication" at a school known for its engineering and hard science programs. Sadly, the school is crappy...except in those fields, so only about 25% of any class had those majors in my "elective."
I had 2 memorable experiences:
Student #1 approached me on day one claiming he just didn;t have time to come to my class for the last half of the 10-week quarter because he would be working on his senior project. After refraining from laughing at his request, I told him I didn't think it would be possible for him "do all the work ahead of time to get it out of the way" and that he'd have to come for the entire 10 weeks. Surprise, surprise, he thanked me at the end of the quarter for actually teaching a course in which he learned stuff. [So many of them always assume Comm courses are all about coming to class, watching movies, and then sitting around and chatting about them.]
Student #2 was in the same course the following term. He was a quiet sort, so I didn't really notice him. But, one day I was discussing the relationship of some new tech to an old medium. He chatted me up about it after class. He started bringing in stuff like it was show-and-tell! He got *involved* in the course and at the end also thanked me for making what he thought would a fluffy elective relevant to his future career.
Good lord! I actually made an impact on 2 young engineers with my frivolous little humanities/social science class. Someone call a priest!
In the end, I think my point is that sometimes people with preconceived notions have no idea what they are talking about and being exposed to other disciplinary stances on the same material is necessary and important. Disciplinary entrenchment gets in the way of education. But, I suspect this is more often obvious in students than faculty [although I do not disbelieve for a second that
some faculty disparage their colleagues is other non-related disciplines].
P.S. It was really nice to be able to talk about students who weren't boneheads for once. Thanks for the inspiration!
