Answer:
Morality outweighs human laws.
Explanation:
The given excerpt from "The Royal House of Thebes" revolves around the story of Antigone and how she disobeyed the order of King Creon to not bury the traitor Polyneices's body. This mythological story is based on the story of Sophocles's "Antigone".
Now, as seen in the excerpt, Creon asked Antigone why she had done what he had prohibited. His edict was to punish anyone who had dared to give Polyneices a proper burial, and Antigone was caught red-handed doing just that. But for Antigone, it was more of doing what is right than obeying the king's order that is against any moral law. She claimed, "The unwritten laws of heaven are not of today nor yesterday but from all time."
Thus, the universal theme that the excerpt shows or represents is that human laws are less important and significant than morality. And in doing right by her brother, Antigone represents the idea that morality outweighs human laws.
