2. The conflict between traditional civilizations and the new elements of industrial civilization break down structures which do not adapt themselves to new conditions. Their framework, sometimes rigid, was the indispensable prop to personal and family life; older people remain attached to it, the young escape from it, as from a useless barrier, to turn eagerly to new forms of life in society. The conflict of the generations is made more serious by a tragic dilemma: whether to retain ancestral institutions and convictions and renounce progress, or to admit techniques and civilizations from outside and reject along with the traditions of the past all their human richness. In effect, the moral, spiritual and religious supports of the past too often give way without securing in return any guarantee of a place in the new world. (Papal Encyclical, Populorum Progressio, 26 Mar 1967).
3. Urban life and industrial change bring strongly to light questions which until now were poorly grasped. What place, for example, in this world being brought to birth, should be given to youth? Everywhere dialogue is proving to be difficult between youth, with its aspirations, renewal and also insecurity for the future, and the adult generations. It is obvious to all that here we have a source of serious conflicts, division and opting out, even within the family, and a questioning of modes of authority, education for freedom and the handing on of values and beliefs, which strikes at the deep roots of society. (Papal Writings, 14 May 1971).
