In Antigone, how does Haemon try to convince Creon to spare the life of Antigone?
In addition to Haemon's pleads for his father to listen to the reasoning of the people of Thebes, Haemon also uses appeals to Creon's authority to convince him to spare Antigone's life. Haemon tells his father that he will forever be his son and that no other union can replace the bond that he has with his father: "[F]or there is no marriage shall occupy a larger place with me than your direction, in the path of honor." Haemon knows that his father likes to be in control, so he submits himself as one of Creon's subjects to make his father feel like he is reasonable and in control. Haemon wants his father to understand that he loves him and that he is not trying to make him appear foolish in front of the people; Haemon tells Creon that "beside your welfare there is nothing more prized by me" to stay in his father's good graces. So, Haemon's appeals to his father's authority are another method that he uses to convince Creon to spare Antigone.
Haemon, being the son of Creon, pleads to his father to listen to the reasoning of the people who, including Haemon, believes Antigone deserves praise for what she has done. He wages with his father to listen to his heart and put aside the laws that are destroying the family, for Creon is stuck between abiding by the laws of the land or the will of the people. Creon bids his son not to "lose you head over this woman" (3.20), but as we learn, Haemon's love prevails. Later, Creon regrets the decison he makes to have Antigone put to death.
