Thus far in Part II we have seen Aquinas follow or rather precede the three Anglo-American theorists of Part I, in learning from Aristotle's ethics and political theory and especially from the Philosopher's political-philosophic foundations. In Chapter 3 we observed Aquinas unearthing and appropriating Aristotle's argument for the naturalness of social and political life for human beings, an argument that seems in turn to entail the conclusion that humans by nature seek to participate in the common good of a just social order and a flourishing civic community, although any particular political community has only a relatively natural status vis-à-vis its members. In Chapter 4 we saw Aquinas comment on Aristotle's second foundation, the argument in Book III of the Politics supporting the centrality to political theory of regimes, citizenship, and civic virtue.
