I am not quick to deny the significance of diversity for education, but I would like to see some proof of it. Certainly, in the hard sciences, it can't possibly make a bit of difference if one's classmates are male, female, black, brown, or yellow. Newton's third law is not subject to opinion based upon your life experience. (The women's libbers have actually contested this, calling it "male science" but they are merely political nut jobs.)
Now, in law school, I suppose a discussion on racial profiling by state troopers might be enlivened by having a few students who actually were pulled over for DWB. This seems somewhat self-evident, but the benefit must be weighed against the Equal Protection Clause of The Fourteenth Amendment. Yes, it would be "nice" and in a perfect world, ideal, if students were represented in the finest schools in numbers approximating their percentages in the overall population. We just can't break the law to make this happen.
I suppose it would be "nice" if 70% of the players in the NBA were white, but I hardly think it would be fair to deprive more qualified athletes of their jobs because they have too much melanin. It would also be "nice" in some cosmic way if 12% of nuclear physicists were black, 13% of first violinists were Hispanic and 70% of the sprinters on the US Olympic team were white, while 30% of the hockey team would be made up of Blacks, Hispanics, Asians, Native Americans, and others.
We must insure that every person is given an opportunity to follow whatever career path he or she chooses, with no impediments placed in his path. Allowing someone to be moved ahead of you in line because he is of the desired ethnicity is just such an impediment.
