Here's an article by Patrick Deneen, a professor at Notre Dame, about how ignorant the kids he teaches are. Nothing personal--they're nice, they're honest, they just don't know basic things about our civilization.
Perhaps he's right, but haven't we been hearing this forever? In fact, Deneen mentions previous Jeremiahs like Allan Bloom and E.D. Hirsch. Except they were complaining thirty years ago--it was Deneen's generation they thought was hopeless.
So if Deneen comes from a cohort that didn't know anything, how can he be surprised that the kids they've been teaching don't know anything?
There may be plenty of problems with the present generation, but ignorance is natural. Almost no one has comprehensive knowledge of our culture entering college, and few have it exiting. The country may be facing serious problems, but in the past we've gotten by with more than enough ignorance of history, literature, science and so on to go around.
I'm surprised Deneen doesn't know that.
