On page two, Haltman is describing Jules Prown's analysis method. Prown says that the most expressive objects are embedded in polarites, such as life and death or acceptance and rejection (Jules Prown). In Cline's article the machete is symbolized in multiple ways in different cultures, such as a weapon in a revolution or an agricultural tool (Cline). In a revolution a machete could symbolize the polarity of power and lack of control. A group revolting is seizing power from an authority.
