"I was captivated by theatrical shows. They were full of representations of my own miseries and fuelled my fire. Why is it that a person should wish to experience suffering by watching grievous and tragic events which he himself would not wish to endure? Nevertheless he wants to suffer the pain given by being a spectator of these sufferings, and the pain itself is his pleasure. What is this but amazing folly? For the more anyone is moved by these scenes, the less free he is from similar passions. Only, when he himself suffers, it is called misery; when he feels compassion for others, it is called mercy. But what quality of mercy is it in fictitious and theatrical inventions? A member of the audience is not excited to offer help, but invited only to grieve. The greater his pain, the greater his approval of the actor in these representations. If the human calamities, whether in ancient histories or fictitious myths, are so presented that the theatregoer is not caused pain, he walks out of the theatre disgusted and highly critical. But if he feels pain, he stays riveted in his seat enjoying himself."
--St. Augustine, Confessions, III.ii.2
