Binary opposition is a theory that originated from two French theorists; Claude Levi-Strausse and Roland Barthes. The theory states that reality can inly exist in the form of ideas, and most importantly, everything comes from something else. For example, the reason we know what 'hot' is is only possible because we also know what 'cold' is. I do believe this theory as it is proven correct in all cases I can think of, especially in film. For example, a villain in a film is only unmoral because the audience know what moral is.
The theorists go on to explain how we, as humans, do this subconciously, that binary opposition is the basic way we learn to understand what things are. As a result all peoples understandings of all things are shaped and determined by knowing what other things are.
