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 defense of the common good of the human spirit. Vainly would one seek to justify such depravation with the pretext of artistic or scientific exigencies, (25) or to deduce an argument from the freedom allowed in this sector by the public authorities.

 
Appeal to Public Authorities

23. To rulers, who are those principally responsible for the common good, and who can do so much to safeguard moral customs, we say: Do not allow the morality of your peoples to be degraded; do not permit that by legal means practices contrary to the natural and divine law be introduced into that fundamental cell, the family. Quite other is the way in which public authorities can and must contribute to the solution of the demographic problem: namely, the way of a provident policy for the family, of a wise education of peoples in respect of moral law and the liberty of citizens.

We are well aware of the serious difficulties experienced by public authorities in this regard, especially in the developing countries. To their legitimate preoccupations we devoted our encyclical letter Populorum Progressio (The Development of Peoples). But with our predecessor Pope John XXIII, we repeat: no solution to these difficulties is acceptable "which does violence to man's essential dignity" and is based only on an utterly materialistic conception of man himself and of his life. The only possible solution to this question is one which envisages the social and economic progress both of individuals and of the whole of human society, and which respects and promotes true human values. (26) Neither can one, without grave injustice, consider divine providence to be responsible for what depends, instead, on a lack of wisdom in government, on an insufficient sense of social justice, on selfish monopolization, or again on blameworthy indolence in confronting the efforts and the sacrifices necessary to ensure the raising of living standards of a people and of all its sons. (27)

May all responsible public authorities-as some are already doing so laudably-generously revive their efforts. And may mutual aid between all the members of the great human family never cease to grow: This is an almost limitless field which thus opens up to the activity of the great international organizations.
