Claude Levi-Strauss was a media theorist who studied hundreds of myths and concluded that humans make sense of the world by seeing binary opposites such as good vs evil, weak vs strong, fast vs slow, man vs nature. He discovered that narratives are structured around these binary oppositions, with the conflict centered around the oppositional climax. Levi-Strauss' theory was that mythic structures are based on the use of binary opposites to define theoretical positions against one another.
