Error is often referred to by the Greek hamartia, and it is best understood as the fatal flaw that brings about a character’s downfall. In the plot of a tragedy, Aristotle argues, there should be some change of fortune—a change from good fortune to bad or vice versa—and that change should arise from some sort of error. For instance, Oedipus’s error (his fatal flaw) in Sophocles’s Oedipus Rex is pride, which causes Oedipus to ignore a god’s prophetic warnings. The best tragedies, Aristotle argues, are those with errors that lead to a change from good fortune to bad fortune, as such tragedies produce the level of fear and pity necessary for the audience to experience catharsis.

This is the sort of person who is not outstanding in moral excellence or justice; on the other hand, the change of bad fortune which he undergoes is not due to any moral defect or depravity, but to an error of some kind. He is one of those people who are held in great esteem and enjoy great good fortune, like Oedipus, Thyestes, and distinguished men from that kind of family.
