Our mortality—the fact that we will die and that we know it—defines the human condition, although this knowledge is often defensively maintained psychically as a theoretical, intellectual proposition. This paper explores one route by which such knowledge is transformed into felt experience: I suggest that how we mourn—what occurs psychically as we live the pain of loss—strongly influences our relationship to our own deaths. Because the psychic labor involved in making mortality real has compelling individual and social consequences, I position the role of the psychoanalyst as well as intersubjective aspects of the psychoanalytic process as central to helping patients grapple with their own mortality.
