Editing Antigone (Sophocles play) (section)

===Natural law and contemporary legal institutions===
Creon's decree to leave Polynices 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.<ref name=MacKay>{{cite journal | last = MacKay | first = L. | title = Antigone, Coriolanus, and Hegel | journal = Transactions and Proceedings of the American Philological Association | volume = 93 | year = 1962 | pages = 178–179 | doi = 10.2307/283759 | jstor = 283759}}</ref> 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 Polynices. Since he is a citizen of Thebes, it would have been natural for the Thebans to bury him. Creon is telling his people that Polynices 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.

In prohibiting the people of Thebes from burying Polynices, Creon is essentially placing him on the level of the other attackers—the foreign Argives. For Creon, the fact that Polynices has attacked the city effectively revokes his citizenship and makes him a foreigner. As defined by this decree, citizenship is based on loyalty. It is revoked when Polynices commits what in Creon's eyes amounts to treason. When pitted against Antigone's view, this understanding of citizenship creates a new axis of conflict. Antigone does not deny that Polynices has betrayed the state, she simply acts as if this betrayal does not rob him of the connection that he would have otherwise had with the city. Creon, on the other hand, believes that citizenship is a contract; it is not absolute or inalienable, and can be lost in certain circumstances. These two opposing views – that citizenship is absolute and undeniable and alternatively that citizenship is based on certain behavior – are known respectively as citizenship 'by nature' and citizenship 'by law.'<ref name=MacKay />
