Oedipus Rex is an example of a research paper on renunciation. Specifically, a tragic experience under certain conditions, which primarily causes the inevitable defeat of a character's will to live by his spiritual aspirations. The process of this defeat necessarily involves suffering and distress that arouse fear and pity (which Aristotle said were to be purged through tragedy). Renunciation is the ultimate result of the intensity of the dramatic conflict between worldliness (the will to live) and spiritual aspiration.
Oedipus' search for his identity is a search for his own guilt. His decision to remain alive, although suffering mutilation and exile, meets the conflicting needs of his devotion to life and his spiritual aspirations. In this way we can estimate the scope of his heroism. Oedipus' conflict is between his moral virtue and his intellectual virtue. To meet his needs verses the needs he feels morally bound to. Oedipus chose the intellect over the moral and suffered for it.
Oedipus’ flaw was his blindness to destiny. If Oedipus Rex had accepted and embraced his destiny, and carved out for himself a life path that would give that destiny meaning. At the core Oedipus is a loving father and husband, a paternal and responsible leader, respectful, generous, compassionate, god-fearing, intelligent, inquisitive, quick thinking, as well as fearless and relentless in the pursuit of truth.
