Writer and historian Agnes Arnold-Forster's most recent book, Nostalgia: A History of a Dangerous Emotion, blends fields such as neuroscience and psychology with social history to explore a feeling that many might view as a simple human fondness for the past. Nostalgia, though, is also vulnerable to misuse, manipulation by unreliable narrators and it often reflects many of our deeper anxieties as a society. Joining her to discuss the book is the scholar, critic and editor Merve Emre, who is Shapiro-Silverberg Professor of Creative Writing and Criticism at Wesleyan University.
