The Decline of Higher Ed?

Via Instapundit, I read this fascinating article on the failure of Colleges to teach the basics; even in physics:

The basic reasons why modern physics is not covered in required courses are identical to the basic reasons why Shakespeare is not covered: (1) the faculty in both cases want to teach their narrow specialty rather than the basic courses in their field, (2) the faculty members in both cases no longer understand the basic material in their own field, (3) the faculty no longer believe there are fundamental truths in their own disciplines. I'm sure that many members of typical university’s English faculty no longer have a basic understanding of Shakespeare. How could they, if they themselves have never taken a course on Shakespeare? A degree in English is no longer a guarantee that the degree holder has a basic knowledge of Shakespeare or other great writers.

Does this mean that some professor's philosophies have spilled over into their view of the world? If one maintains a moral relativist view, why would that not apply to everything else they believe?
