Association demands of its components only this, that they undertake a function which contributes to achieving its constitutive purpose. Association lays no claim upon their entire inner being. But matters are otherwise with the genuine community. Within the community, and thus within the individuals that belong to it, there lives an inclination to reach out beyond themselves toward a complete unification. Before it stands the image of a complete community that can't be achieved by any earthly community -- can't in principle, not just accidentally. However, the possibility of complete community becomes insightfully given, on the basis of what can be achieved in the midst of the earthly community toward overcoming absolute loneliness. Consequently, an inner incompleteness clings to every earthly community, and an inclination beyond itself.
