A series of differing explanations of a puzzling case of psychosomatic illness introduces some reflections on a century's history of psychoanalytic interest in the mind-body problem. Freud and Janet explained the physical symptoms of hysteria using radically different models of the mind. Since then Janet's model, banished early on, has returned to haunt the castle of psychoanalysis. The enduring influence of Janet's model on subsequent thought in this field, especially that of Marty and de M'Uzan, Sifneos, LeDoux, and others, is traced, as is the influence of Freud's model on Groddeck, Alexander, McDougall, Fonagy, and others. It is argued that although these models are vastly different at one level of abstraction, at a higher level they share an important set of assumptions.
