heuristic juxtaposition

"Juxtaposition functions as a heuristic, an invention strategy that has been used within the context of media and writing by Walter Benjamin in the Arcades project, William S. Burroughs and Bryon Gysin with the cut-up method, and McLuhan in Understanding Media. These writers used juxtaposition as a rhetorical device for creating associations and emotional responses out of the combination of unlike words and images, but they did so within the context of media."
