Hittinger on "The Coherence of the Four Basic Principles of Catholic Social Doctrine"

Everything Russell Hittinger writes about the Church's social teachings is worth reading, so I suppose there's no need to say that this essay, "The Coherence of the Four Basic Principles of Catholic Social Doctrine:  An Interpretation", is, too.  (The "four basic principles" he discusses are human dignity, solidarity, subsidiarity, and the common good.)  Along the way, there's a lot about "social ontology" and the challenge that the Catholic understanding of persons poses to methodological individualism, and to some understandings of religious freedom.
