Tragic art, as it developed in the theaters of ancient Greece, in the fifth century B.C., was essentially an art form devoted to tracing how people fail, and also according them a level of sympathy, which ordinary life would not necessarily accord them. A few years ago, I was thinking about this, and I went to "The Sunday Sport," a tabloid newspaper I don't recommend you start reading if you're not familiar with it already.
