The nature of tragedy has always been felt to be a problem, not only by the philosopher, but also, and perhaps even more, by the ordinary man. The question so often asked is: why, if there is so much suffering already in the world, do we want to go to a theatre or read a story describing more suffering? Why indeed should the spectacle of suffering ever be pleasing to us? Yet it is obvious that olarge numbers of ordinary people do like reading or seeing tragedies; and that there are some tragedies which are generally judged to be the most valuable works of literary art ever produced. What then is the nature of the value which we extract from these works? That is the question to which I would like to address myself.
