I wrote on the board one of my favorite lines from the German thinker Theodor Adorno: “The highest form of morality is not to feel at home in one’s own home.” I explained that most great works of the imagination were meant to make you feel like a stranger in your own home. The best fiction always forced us to question what we took for granted. It questioned traditions and expectations when they seemed too immutable. I told my students I wanted them in their readings to consider in what ways these works unsettled them, made them a little uneasy, made them look around and consider the world, like Alice in Wonderland, through different eyes.
