No. From now on, where oracles are concerned,
I would not waste a second thought on any. (807-813)
Jocasta is showing a great amount of hubris in this statement. Oracles are messages from the voice of the gods, and therefore, are accepted to be true. By believing that the oracles are unreliable, she is showing major disrespect to the gods and displaying arrogance in herself. In this occasion, Jocasta is also fully aware of the rules of respecting the gods. Despite this knowledge, she decides to display her arrogance and disbelief in the oracles, the voice of the gods. As a result, this is a case of hubris while knowing, and cannot be deemed justifiable. The last case of hubris displayed by Jocasta is when she tries to stop Oedipus from discovering that the prophecies have been true all along. By this time in the play, Jocasta has just put all the pieces together and is going through an anagnorisis, a moment of realization. In order to stop this embarrassing news from coming out, she tries to convince Oedipus not to believe the shepherd. Jocasta states:
Forget this herdsman. Forget it all.
This talk is a waste of time. . .
