Social Theory and the Principium Unitatis

Complex as is the immediate situation of social theory, a general view reveals some significant continuities, both spatial and temporal. The attitude of the pluralists, whether in theory or in practice, to the sovereign nation-state has more common ground than at first appears with that of the states themselves toward the nascent organs of international government; and the dilemma underlying both controversies is in fact nothing less than a restatement, in modern ideology, of an issue fundamental to the history of the entire Christian era.That issue, stated in the broadest terms, centers about the relation between de facto and de jure sovereignty; or, more broadly still, between political and ethical, secular and spiritual, authority; and its importance may be suggested by the generalization that security in social relations is attainable, and has in fact been attained, only when the de facto, or political, sovereign—whatsoever form it may take—has been substantially integrated with the immediate source of ethical or moral authority. The pre-modern period of history abounds in statements, both factual and doctrinal, of this issue.
