Book excerpt: After Injury explores the practices of forgiveness, resentment, and apology in three key moments when they were undergoing a dramatic change. The three moments are early Christian history (for forgiveness), the shift from British eighteenth-century to Continental nineteenth-century philosophers (for resentment), and the moment in the 1950s postwar world in which British ordinary language philosophers and American sociologists of everyday life theorized what it means to express or perform an apology. The debates that arose in those key moments have largely defined our contemporary study of these practices.
