To the reasons above alleged, a memorable experience brings confirmation: I mean that state of mankind which the Son of God, when He would for man's salvation take man upon Him, either waited for, or ordered when so He willed. For if from the fall of our first parents, which was the starting-point of all our wanderings, we retrace the various dispositions of men and their times, we shall not find at any time, except under the divine monarch Augustus, when a perfect monarchy existed, that the world was everywhere quiet. And that then mankind was happy in the tranquillity of universal peace, this all writers of history, this famous poets, this even the Scribe of the meekness of Christ has deigned to attest. And lastly, Paul has called that most blessed condition, the fulness of time. Truly time, and the things of time, were full, for no mystery of our felicity then lacked its minister. But how the world has gone on from the time when that seamless robe was first torn by the claws of covetousness, we may read, and would that we might not also see. O race of men, by how great storms and losses, by how great shipwrecks hast thou of necessity been vexed since, transformed into a beast of many heads, thou hast been struggling different ways, sick in understanding, equally sick in heart. The higher intellect, with its invincible reasons, thou reckest not of; nor of the inferior, with its eye of experience; nor of affection, with the sweetness of divine suasion, when the trumpet of the Holy Ghost sounds to thee--"Behold, how good is it, and how pleasant, brethren, to dwell together in unity."--_De Monarch._ lib. i. p. 54. Yet this great Roman empire existed still unimpaired in name--not unimposing even in what really remained of it. Dante, to supply a want, turned it into a theory--a theory easy to smile at now, but which contained and was a beginning of unknown or unheeded truth. What he yearns after is the predominance of the principle of justice in civil society. That, if it is still imperfect, is no longer a dream in our day; but experience had never realised it to him, and he takes refuge in tentative and groping theory. The divinations of the greatest men have been vague and strange, and none have been stranger than those of the author of the _De Monarchia_. The second book, in which he establishes the title of the Roman people to Universal Empire, is as startling a piece of mediæval argument as it would be easy to find.
