When I was in graduate school, a bunch of us got together to go over to Cambridge for our French and German reading exams. We had lunch together, and naturally the conversation turned to coursework. One guy in my Chaucer class said he loved modern, but he really felt Chaucer was like an alien -- he couldn't really make head nor tail of him. I had an equal but opposite reaction -- I felt perfectly at home with Chaucer, but the modern novel course I actually had to teach a discussion section of was to me full of ugly and alien and incomprehensible "ideas" -- if that's exactly the word.
With Terence I can say "Nothing human is alien to me," only with the qualifier "as long as it's not literature after the 18th century. Go ahead, consign me to the dustbin of history!
