Repetition

"Just as people know or feel that advertisements and political platforms must not be necessarily true or right, and yet hear and read them and even let themselves be guided by them, so they accept the traditional values and make them part of their mental equipment.  If mass communications blend together harmoniously, and often unnoticeably, art, politics, religion, and philosophy with commercials, they bring these realms of culture to their common denominator—the commodity form.  The music of the souls is also the music of salesmanship. Exchange value, not truth value counts.  On it centers the rationality of the status quo, and all alien rationality is bent to it."

- From One-Dimensional Man by Herbert Marcuse
