Jacques Ellul observes in Propaganda: When dialogue begins, propaganda ends. His theme, that propaganda is not this or that ideology but rather the action and coexistence of all media at once, explains why propaganda is environmental and invisible. The total life of any culture tends to be "propaganda", for this reason. It blankets perception and supresses awareness, making the counter environments created by the artist indispensable to survival and freedom.
