1. 'The true interest of everything is to conform to its own constitution and nature; and my nature owns reason and social obligation. Socially, as Antoninus, I have for my city and country Rome; as a man, the world.'[1]

2. The mediaeval ideal[2]—of the sacerdotium, as of Pope Hildebrand; of the imperium, as of Frederick Barbarossa; of the studium, in the thought of Aquinas, on one side, as well as in the thought of Dante,[3] on the other side—is the unity and concord of the Christian Commonwealth, whether a

And so it is plain that Monarchy or the Empire is necessary for the welfare of the world' (bk. i. v.). 'And as the part is to the whole, so is the order of parts to the order of the whole (sic ordo partialis ad totalem). The part is to the whole, as to an end and highest good which is aimed at; and, there-
