It's pretty clear that in 2017, diversity of opinion is a very low priority for universities. Do you think this has ever been any different? I wonder. At one point, I think a university education served, sociologically, as another barrier separating the upper class from the rabble. Do you think diversity of opinion was perhaps more tolerated when the only students were children of the rich? Would universities have defended their cultural values as ardently as they do now, when membership in that culture was enforced differently?
