Vigilanti Cura §25

²⁵ The power of the motion picture consists in this, that it speaks by means of vivid and concrete imagery which the mind takes in with enjoyment and without fatigue. Even the crudest and most primitive minds which have neither the capacity nor the desire to make the efforts necessary for abstraction or deductive reasoning are captivated by the cinema. In place of the effort which reading or listening demands, there is the continued pleasure of a succession of concrete and, so to speak, living pictures.
