In Oedipus the King, Oedipus is a seeker of knowledge and truth. He struggles to uncover Laius’s murder and his own identity, despite numerous warnings that he should leave the truth alone. His pursuit of knowledge and truth, however, results in ruin as Oedipus uncovers his destiny, which he was better off not knowing. This suggests that knowledge is futile and limited in its ability to bring happiness to those who seek it.
Knowledge is a burden and ultimately a death threat to those who possess it in the Oedipus the King.
