It is amazing how many undergraduates are poking around for courses to take, without any plan or question to ask, just filling up their college years. In fact, with rare exceptions, the courses are parts of specialties and not designed for general cultivation, or to investigate questions important for human beings as such. The so-called knowledge explosion and increasing specialization have not filled up the college years but emptied them. Those years are impediments; one wants to get beyond them. And in general the persons one finds in the professions need not have gone to college, if one is to judge by their tastes, their fund of learning or their interests.
