Levi Strauss narrative theory

Claude Levi Strauss was a french anthropologist and ethnologist. He came up with the theory of Binary Opposites meaning that every narrative has an opposite of something.

Examples:

• Hero - villan
• Good - Bad
• Rural - Urban
• Innocent - Corrupt 
• Human - Inhuman 

And the list goes on but the point is that the conflict of binary opposites is what makes the climax of the narrative structure. Each Binary Opposite has a clear contrast.
