26 Every day human interdependence grows more tightly drawn and spreads by degrees over the whole world. As a result the common good, that is, the sum of those conditions of social life which allow social groups and their individual members relatively thorough and ready access to their own fulfillment, today takes on an increasingly universal complexion and consequently involves rights and duties with respect to the whole human race. Every social group must take account of the needs and legitimate aspirations of other groups, and even of the general welfare of the entire human family. At the same time, however, there is a growing awareness of the exalted dignity proper to the human person, since he stands above all things, and his rights and duties are universal and inviolable. Therefore, there must be made available to all men everything necessary for leading a life truly human, such as food, clothing, and shelter; the right to choose a state of life freely and to found a family, the right to education, to employment, to a good reputation, to respect, to appropriate information, to activity in accord with the upright norm of one's own conscience, to protection of privacy and rightful freedom even in matters religious. Hence, the social order and its development must invariably work to the benefit of the human person if the disposition of affairs is to be subordinate to the personal realm and not contrariwise, as the Lord indicated when He said that the Sabbath was made for man, and not man for the Sabbath. This social order requires constant improvement. It must be founded on truth, built on justice and animated by love; in freedom it should grow every day toward a more humane balance. An improvement in attitudes and abundant changes in society will have to take place if these objectives are to be gained. God's Spirit, Who with a marvelous providence directs the unfolding of time and renews the face of the earth, is not absent from this development. The ferment of the Gospel too has aroused and continues to arouse in man's heart the irresistible requirements of his dignity.
