This notion cannot help but have economic applications. Being naturally endowed with intelligence and free will, man tends, by his own spiritual faculties, to draw from himself all the necessary qualities to provide for his welfare. This in turn gives rise to unique expressions of self-sufficiency.
From the very beginning of economy around the hearth of the home, man turned vigorously inward seeking to sustain the family. Likewise, he developed intermediary associations of kinship, community, and Faith by turning inward, seeking to advance the material and spiritual well-being of members. Larger associations such as cities, regions, and even nations, forming concentric circles of concern, shared in this inward development and self-expression where each group took care of its own and, by the principle of subsidiarity, had recourse to a higher order only when necessary.
