This article aims at analysing Aristotle's poetic conception of catharsis to assess whether it may be of help in enlightening the particular didactic challenges involved when training medical students to cope morally with complex or tragic situations of medical decision-making. A further aim of this investigation is to show that Aristotle's criteria for distinguishing between history and tragedy may be employed to reshape authentic stories of sickness into tragic stories of sickness. Furthermore, the didactic potentials of tragic stories of sickness will be tried out. The ultimate aim is to investigate whether the possibilities of developing a therapeutic conception of medical ethics researched in a previous article on catharsis and moral therapy in Plato may be strengthened through the hermeneutics of the Aristotelian conception of tragic catharsis.
