‘”Is it a great sorrow”, Jocasta asks, “to be deprived of your homeland?”
And Polyneices replies: “Great indeed. Much worse than it sounds”.
Jocasta: “What is this sorrow, what is the exile’s greatest misfortune?”
Polyneices: “The biggest drawback: he does not have parresia, [the power of the word, the power to talk].”‘
