Excitation of the human senses

Everything in the modern media of social communications which leads to sense excitation and unbridled customs, as well as every form of pornography and licentious performances, must arouse the frank and unanimous reaction of all those who are solicitous for the progress of civilization and the defence of the common good of the human spirit. Vainly would one seek to justify such depravation with the pretext of artistic or scientific exigencies, or to deduce an argument from the freedom allowed in this sector by the public authorities. (Papal Encyclical, Humanae Vitae, 1968).
