The myth of Oedipus . . . arouses powerful intellectual and emotional reactions in the adult-so much so, that it may provide a cathartic experience, as Aristotle taught all tragedy does. [A reader] may wonder why he is so deeply moved; and in responding to what he observes as his emotional reaction, ruminating about the mythical events and what these mean to him, a person may come to clarify his thoughts and feelings. With this, certain inner tensions which are the consequence of events long past may be relieved; previously unconscious material can then enter one's awareness and become accessible for conscious working through. This can happen if the observer is deeply moved emotionally by the myth, and at the sametime strongly motivated intellectually to understand it.
