The science revolution attributed to Thales began gaining political force, and this play offered a warning to the new thinkers. Kitto interprets the play as Sophocles' retort to the sophists , by dramatizing a situation in which humans face undeserved suffering through no fault of their own, but despite the apparent randomness of the events, the fact that they have been prophesied by the gods implies that the events are not random, despite the reasons being beyond human comprehension.  Through the play, according to Kitto, Sophocles declares "that it is wrong, in the face of the incomprehensible and unmoral, to deny the moral laws and accept chaos. What is right is to recognize facts and not delude ourselves. The universe is a unity; if, sometimes, we can see neither rhyme nor reason in it we should not suppose it is random. There is so much that we cannot know and cannot control that we should not think and behave as if we do know and can control. 
Creon's decree to leave Polyneices unburied in itself makes a bold statement about what it means to be a citizen, and what constitutes abdication of citizenship. It was the firmly kept custom of the Greeks that each city was responsible for the burial of its citizens. Herodotus discussed how members of each city would collect their own dead after a large battle to bury them.  In Antigone , it is therefore natural that the people of Thebes did not bury the Argives, but very striking that Creon prohibited the burial of Polyneices. Since he is a citizen of Thebes, it would have been natural for the Thebans to bury him. Creon is telling his people that Polyneices has distanced himself from them, and that they are prohibited from treating him as a fellow-citizen and burying him as is the custom for citizens.
When animals are taken from their natural habitat, they are placed in secluded cages where their natural habitat is recreated, to the best of the zoo’s abilities. However, certain aspects such as ambient temperature in an animal’s natural habitat cannot be recreated perfectly. Animals live around the world for a reason. The main reason is that their natural habitat is associated with a particular climate and eco system, one which is reliant upon all of the natural plants and animals who also share that habitat. Nocturnal animals are those who sleep during the day and forage during the night. When nocturnal animals are taken from their natural habitat and placed inside of a zoo, with standard day time operating hours, it can be incredibly difficult for the animals to maintain their normal sleeping and activity plans due to a high rate of traffic often banging on their cage or calling to them during the day.
