What theme does Oedipus Rex primarily explore?

The theme of the consequences of ignorance and knowledge is central to "Oedipus Rex." Throughout the play, Oedipus embarks on a quest for truth, seeking to uncover the identity of King Laius's murderer and the causes of the plague afflicting Thebes. His journey emphasizes the painful revelation of knowledge, particularly the self-discovery of his actions and identity.

As Oedipus gathers information, he transitions from ignorance to a harsh understanding of his own fate, which aligns with the idea that knowledge can lead to suffering. The irony of his situation is profound; he believes himself to be wise and resourceful, yet he is tragically blind to the truth of his circumstances until it is too late. This exploration of how ignorance can protect individuals while simultaneously leading to catastrophic outcomes reinforces the idea that the pursuit of knowledge is fraught with peril. The catastrophic realization that he has unknowingly fulfilled the prophecy shapes the tragedy of the play and underscores the significance of this theme.
