1882 Certain societies, such as the family and the state, correspond more directly to the nature of man; they are necessary to him. To promote the participation of the greatest number in the life of a society, the creation of voluntary associations and institutions must be encouraged "on both national and international levels, which relate to economic and social goals, to cultural and recreational activities, to sport, to various professions, and to political affairs." 5 This "socialization" also expresses the natural tendency for human beings to associate with one another for the sake of attaining objectives that exceed individual capacities. It develops the qualities of the person, especially the sense of initiative and responsibility, and helps guarantee his rights. 6
1883 Socialization also presents dangers. Excessive intervention by the state can threaten personal freedom and initiative. The teaching of the Church has elaborated the principle of subsidiarity, according to which "a community of a higher order should not interfere in the internal life of a community of a lower order, depriving the latter of its functions, but rather should support it in case of need and help to co- ordinate its activity with the activities of the rest of society, always with a view to the common good." 7
