I think people who teach literature courses should do more of it. Jonathan is teaching Jesus' Son in his sophomore literature survey course, and I mentioned to him that maybe I should come and do a short guest appearance in his class, just to get up in front of the students and say, "OMG YOU GUYS, this book is SOOOO GOOOOOOD" and the like. I know he won't do it. The professors I had in college never gushed either. It was always just "okay, for Thursday, read 'Among School Children' and 'The Second Coming.'"
How is it that so many people come to read the Twilight or Harry Potter books? People they know gush about them, and their enthusiasm motivates. Do you teach literature? Do you make a point of showing strong enthusiasm about the works you teach?
