As the Greeks developed it, the tragic form, more than any other, raised questions about human existence. Why must humans suffer? Why must humans be forever torn between the seeming irreconcilable forces of good and evil, freedom and necessity, truth and deceit? Are the causes of suffering outside of oneself, in blind chance, in the evil designs of others, in the malice of the gods? Are its causes internal, and does one bring suffering upon oneself through arrogance, infatuation, or the tendency to overreach? Why is justice so elusive?
