Two brothers, Arnold and Frederique, live in an island nation inhabited by 2 groups of people known as Civics and Savages. Everyone belongs to one group or the other. A civic always states what he believes to be true and a savage always states what he believes to be false. However, an inhabitant can also be sane or insane. A sane person always knows the truth for the truth, while an insane person always believes the truth to be a lie and a lie to be the truth.
Both Arnold and Frederique are brought before a judge in a murder case. The court proceedings are as follows:
ARNOLD: Frederique is insane!
FREDERIQUE: Yeah? Well, Arnold is a Savage!
ARNOLD: How DARE you? Well, I'll show goodwill. Frederique is a Civic.
FREDERIQUE: Doesn't change the fact that Arnold is insane.
As Arnold attacks his twin with a chair, the judge contemplates: what type of people are Arnold and Frederique? The name of the next page will be that, in the order of their names, with the format insanesavageinsanesavage.html.
