The gods have us in their grip. Contrast this with Jocasta's philosophy. Not a man on earth can see a day ahead, groping through the dark. Better to live at random. Live Oedipus, as if there is no tomorrow.
Destinies are indeterminate and uncontrollable.
I want to take a detour first through the Book of Job. The point of the exercise is to illustrate just how different interpretive possibilities can be. When William Blake analyzed the Book of Job in the last century he became disturbed at the so-called arrangement between God and his servant Satan to test Job. That idea was unsatisfactory to William Blake. Only a false God would have listened to Satan.
