Final answer:
The downfall of a tragic hero stems from their own tragic flaw or hamartia, as well as the unfolding events of the plot, according to Aristotle's Poetics.
Step-by-step explanation:
The downfall of a tragic hero is generally not just the result of external events but is also significantly attributed to the hero's own hamartia, or tragic flaw. According to Aristotle's Poetics, a tragic hero is typically a character of noble stature and greatness who possesses a flaw that leads to their downfall. This flaw, known as hamartia, combines with the plot's peripeteia (reversal of fortune) and ultimately brings about the hero's demise. In Greek tragedies, such as Sophocles' Antigone, where Creon exhibits hubris, or in the case of Oedipus' arrogance in Oedipus Rex, the tragic hero's downfall is a result of both their own decisions and the unfolding events which evoke pity and fear, leading to catharsis for the audience. Aristotle underscores the importance of the tragic hero's error being relatable to the greater community, thus providing both a moral lesson and an emotional experience for the audience.
A tragic hero, as defined by Aristotle, is the focal character of a tragedy who is mostly good but has a fatal flaw (hamartia) that leads to their downfall. This downfall is often the result of events conspiring against the tragic hero. The character goes through plot elements such as a reversal of fortune, recognition of their tragic flaw, and ultimately experiences a purgation of pity and fear. An example of a tragic hero is Creon in Sophocles' Antigone, who is too prideful and suffers the consequences of his flaw.
