Famous quotes containing the words goals and/or mass:
“Despicable means used to achieve laudable goals renders the goals themselves despicable.”
—Anton Pavlovich Chekhov (1860–1904)
“Commercial jazz, soap opera, pulp fiction, comic strips, the movies set the images, mannerisms, standards, and aims of the urban masses. In one way or another, everyone is equal before these cultural machines; like technology itself, the mass media are nearly universal in their incidence and appeal. They are a kind of common denominator, a kind of scheme for pre-scheduled, mass emotions.”
—C. Wright Mills (1916–62)
