"Now I believe it is by the laws of heaven that man must live." * Haemon says this to his father to show that he once sided with Creon, but has now reconsidered. The Sentry said this to Creon because the Sentry allowed someone to bury Polynices. Creon said this at the end of the story when he realized that he was wrong and experienced catharsis. Ismene said this to Creon when she changed her mind and insisted on dying with Antigone.

I'm not going to write 150 words lol, but i will you with giving you examples of how they kept the animal population from revolting. napoleon made a list of rules, and told everyone how "important they are even though he was known to break them and then have them changed by the only animal who could read on the farm. none of the animals were intelligent enough to read, so they never knew if they had been changed or not which was an advantage to napoleon. napoleon constantly reminded them that if they revolted they would have to go back to mr. jones' way of things, which in retrospect was "worse" (wasn't really worse though, he was just saying that to intimidate since he didn't wanna lose his power). one of the main reasons they revolted in the first place was food, and of course if they revolt napoleon will not share food with them.
