The intellectual phenomenon is a strange one. It would be less strange if Dante were arguing in the schools, or pleading for a party. But even Henry of Luxemburg cared little for such a throne as the poet wanted him to fill, much less Can Grande and the Visconti. The idea, the theory, and the argument, are of the writer's own solitary meditation. We may wonder. But there are few things more strange than the history of argument. How often has a cause or an idea turned out, in the eyes of posterity, so much better than its arguments. How often have we seen argument getting as it were into a groove, and unable to extricate itself, so as to do itself justice. The everyday cases of private experience, of men defending right conclusions on wrong or conventional grounds, or in a confused form, entangled with conclusions of a like yet different nature;--of arguments, theories, solutions, which once satisfied, satisfying us no longer on a question about which we hold the same belief--of one party unable to comprehend the arguments of another--of one section of the same side smiling at the defence of their common cause by another--are all reproduced on a grander scale in the history of society. There too, one age cannot comprehend another; there too it takes time to disengage, subordinate, eliminate. Truth of this sort is not the elaboration of one keen or strong mind, but of the secret experience of many; "_nihil sine ætate est, omnia tempus expectant_." But a counterpart to the _De Monarchia_ is not wanting in our own day; theory has not ceased to be mighty. In warmth and earnestness, in sense of historic grandeur, in its support of a great cause and a great idea, not less than in the thought of its motto, [Greek: heis koiranos estô], De Maistre's volume _Du Pape_, recalls the antagonist _De Monarchia_; but it recalls it not less in its bold dealing with facts, and its bold assumption of principles, though the knowledge and debates of five more busy centuries, and the experience of modern courts and revolutions, might have guarded the Piedmontese nobleman from the mistakes of the old Florentine.
