What is a major theme in Oedipus Rex?

A major theme in "Oedipus Rex" is the search for knowledge and its consequences. Oedipus, in his determination to uncover the truth about his identity and the murder of King Laius, embarks on a relentless quest for knowledge. This pursuit, while admirable in its essence, leads to devastating revelations. Oedipus learns that he has unwittingly fulfilled the prophecy of killing his father and marrying his mother.

The consequences of this search for knowledge are profound; it ultimately results in Oedipus's tragic downfall. His inability to accept the truth and the horrifying results of his inquiries highlight the play’s exploration of knowledge as a double-edged sword. Gaining knowledge about oneself and one’s fate can lead to enlightenment but can also cause immense suffering, reflecting the complex nature of truth in human experience. This theme resonates throughout the play, emphasizing the idea that the quest for truth is fraught with peril.
