Like many of my friends, I’ve spent the past few weeks anxiously awaiting the series finale of Mad Men. I started watching a bit late, but caught up, and eagerly watched each week in April and May to find out how show creator Matthew Weiner would leave the stories of the main characters. And in the past few days, I’ve been mulling over the finale and in particular how it ended. Then yesterday, I realized that the finale of a beloved TV series actually has quite a bit to tell us (and possibly our students) about the omnipresent specter of teleology in the study of the past. [NOTE: Spoilers ahead, just in case.]
