Mater et Magistra §211

²¹¹ Furthermore, the increasing sense of dissatisfaction with worldly goods which is making itself felt among citizens of the wealthier nations, is rapidly destroying the treasured illusion of an earthly paradise. Men, too, are becoming more and more conscious of their rights as human beings, rights which are universal and inviolable; and they are aspiring to more just and more human relations with their fellows. The effect of all this is to make the modern man more deeply aware of his own limitations, and to create in him a striving for spiritual values. All of which encourages Us in the hope that individuals and nations will one day learn to unite in a spirit of sincere understanding and profitable cooperation.
