Predicting the future is hard. It’s easy to instinctively turn to science to tell us where we’re going, but that’s usually only half the story. For as long as I can remember, I’ve been enthralled by fiction’s ability to evoke ideas that end up pertaining to science. In this essay, from a class I took on philosophy of mind some years ago, I discuss the movie Eternal Sunshine of the Spotless Mind, in which Jim Carey takes advantage of a new neurodevice that allows a person to completely ablate bad memories, in this case, memories of his ex. I think the movie raises several questions that are becoming more pertinent all the time (and it doesn’t help that it’s a beautiful performance, give it a watch!).
