“In addition to this there is the pluralization of the world in which we live through the division between public and private spheres, and also the plurality of institutions within the public sphere. Each of them forms a world in itself, so that individuals have to move to and fro between different worlds. The integration of this plurality of aspects of the world, which used to be achieved by religion, no longer takes place in the public world of secular culture but has to be achieved by the individual. The basis of this is meant to be the private sphere of life, the world of the family. But in many cases this cannot stand up to the burdens imposed by modern life. The growth of urban living has contributed to an increase of pluralization in the private sphere also, making the task of integration increasingly difficult.”
