This article closely examines the way in which Thomas Aquinas understood the relationship between the various forms of human community. The article focuses on Aquinas's theory of law and politics and, in particular, on his use of political categories, such as city, province and empire, together with the associated concepts of kingdom and nation, as well as various social groupings, such as household, clan and village, alongside of the distinctly ecclesiastical categories of parish, diocese and universal church. The analysis of these categories is used in the article to help explain Aquinas's role in the development of theories about subsidiarity, federalism and mixed constitutionalism. In the first place, it is argued that a close inquiry into Aquinas's discussion of the many and various forms of human community sheds light on the origins and development of the idea of subsidiarity within Catholic social teaching. Second, while Aquinas certainly did not advance a theory of federalism as that idea is presently understood, it is argued that recovering what Aquinas had to say about the categories of human community helps us to understand the origin and later development of federal ideas. Finally, it is argued that far from endorsing a system of absolute monarchy as is sometimes alleged, when understood in this way, Aquinas supported a particular kind of mixed constitution in which monarchy is tempered by a variety of constitutional constraints founded upon a conception of the body politic as itself constructed out of a plurality of smaller, intermediate corporations and communities of a political, ecclesiastical and social character.

By analysing original sources and evaluating conceptual frameworks, this book discusses the idea proclaimed in the Preamble to the Constitution that Australia is a federal commonwealth. Taking careful account of the influence which the American, Canadian and Swiss Constitutions had upon the framers of the Australian Constitution, the author shows how the framers wrestled with the problem of integrating federal ideas with inherited British traditions and their own experiences of parliamentary government. In so doing, the book explains how the Constitution came into being in the context of the groundswell of federal ideas then sweeping the English-speaking world. In advancing an original argument about the relationship between the formation of the Constitution, the representative institutions, configurations of power and amending formulas contained therein, fresh light is shed on the terms and structure of the Constitution and a range of problems associated with its interpretation and practical operation are addressed.

The philosophical origins of the principle of subsidiarity must be understood historically. This chapter argues that the critical point for the emergence of the principle lay in Thomas Aquinas’s theological interpretation of Aristotle’s political philosophy and his application of it to the institutional pluralism of medieval Europe. From Aristotle, Aquinas developed the idea that human societies naturally progress from families, through villages to entire city-states, but he recognised that what Aristotle said of city-states could be applied not only to cities but even more emphatically to political communities on the scale of provinces, kingdoms and empires. Moreover, for Aquinas, the civil order was not the only ‘perfect community’ in Aristotle’s sense: there was also the church in all of its many grades and jurisdictions, alongside the many different religious orders and fraternities of medieval Europe, some of them also organised into their own graded hierarchies. Reflecting on the complexity of the society surrounding him, Aquinas acknowledged the many and various purposes for which various associations and forms of human community exist and are formed, giving rise to a whole host of familial, geographical, professional, mercantile, scholarly and other specialised societies. All of these groups and groupings, from the smallest to the largest, have their place and their proper function, according to Aquinas, and each should to be allowed to make its unique and special contribution as a means to integral human fulfillment, without undue interference from any others, including the state.
