Such has been the accumulated wealth of literature, and so rapid the advances of science among us since the close of the Middle Ages, that it is not now possible by any effort fully to enter into the feelings with which the relics of antiquity were regarded by those who saw in them their only possession. It is indeed true that modern art and literature and philosophy have been produced by the working of new minds upon old materials: that in thought, as in nature, we see no new creation. But with us the old has been transformed and overlaid by the new till its origin is forgotten: to them ancient books were the only standard of taste, the only vehicle of truth, the only stimulus to reflection. Hence it was that the most learned man was in those days esteemed the greatest: hence the creative energy of an age was exactly proportioned to its knowledge of and its reverence for the written monuments of those that had gone before. For until they can look forward, men must look back: till they should have reached the level of the old civilization, the nations of mediæval Europe must continue to live upon its memories. Over them, as over us, the common dream of all mankind had power; but to them, as to the ancient world, that golden age which seems now to glimmer on the horizon of the future was shrouded in the clouds of the past. It is to the fifteenth and sixteenth Revival of learning and literature, A.D. 1100-1400. centuries that we are accustomed to assign that new birth of the human spirit—if it ought not rather to be called a renewal of its strength and quickening of its sluggish life—with which the modern time begins. And the date is well chosen, for it was then first that the transcendently powerful influence of Greek literature began to work upon the world. But it must not be forgotten that for a long time previous there had been in progress a great revival of learning, and still more of zeal for learning, which being caused by and directed towards the literature and institutions of Rome, might fitly be called the Roman Renaissance. The twelfth century saw this revival begin with that passionate study of the legislation of Justinian, whose influence on the doctrines of imperial prerogative has been noticed already. The thirteenth witnessed the rapid spread of the scholastic philosophy, a body of systems most alien, both in subject and manner, to anything that had arisen among the ancients, yet one to whose development Greek metaphysics and the theology of the Latin fathers had largely contributed, and the spirit of whose reasonings was far more free than the presumed orthodoxy of its conclusions suffered to appear. In the fourteenth century there arose in Italy the first great masters of painting and song; and the literature of the new languages, springing into the fulness of life in the Divina Commedia, adorned not long after by the names of Petrarch and Chaucer, assumed at once its place as a great and ever-growing power in the affairs of men.

Growing freedom of spirit.

Now, along with the literary revival, partly caused by, partly causing it, there had been also a wonderful stirring and uprising in the mind of Europe. The yoke of church authority still pressed heavily on the souls of men; yet some had been found to shake it off, and many more murmured in secret. The tendency was one which shewed itself in various and sometimes apparently opposite directions. The revolt of the Albigenses, the spread of the Cathari and other so-called heretics, the excitement created by the writings of Wickliffe and Huss, witnessed to the fearlessness wherewith it could assail the dominant theology. It was present, however skilfully disguised, among those scholastic doctors who busied themselves with proving by natural reason the dogmas of the Church: for the power which can forge fetters can also break them. It took a form more dangerous because of a more direct application to facts, in the attacks, so often repeated from Arnold of Brescia downwards, upon the wealth and corruptions of the clergy, and above all of the papal court. For the agitation was not merely speculative. There was beginning to be a direct and rational interest in life, a power of applying thought to practical ends, which had not been seen before. Influence of thought upon the arrangements of society. Man's life among his fellows was no longer a mere wild beast struggle; man's soul no more, as it had been, the victim of ungoverned passion, whether it was awed by supernatural terrors or captivated by examples of surpassing holiness. Manners were still rude, and governments unsettled; but society was learning to organize itself upon fixed principles; to recognize, however faintly, the value of order, industry, equality; to adapt means to ends, and conceive of the common good as the proper end of its own existence. In a word, Politics had begun to exist, and with them there had appeared the first of a class of persons whom friends and enemies may both, though with different meanings, call ideal politicians; men who, however various have been the doctrines they have held, however impracticable many of the plans they have advanced, have been nevertheless alike in their devotion to the highest interests of humanity, and have frequently been derided as theorists in their own age to be honoured as the prophets and teachers of the next.

Separation of the peoples of Europe into hostile kingdoms: consequent need of an international power.

Now it was towards the Roman Empire that the hopes and sympathies of these political speculators as well as of the jurists and poets of the fourteenth and fifteenth centuries were constantly directed. The cause may be gathered from the circumstances of the time. The most remarkable event in the history of the last three hundred years had been the formation of nationalities, each distinguished by a peculiar language and character, and by steadily increasing differences of habits and institutions. And as upon this national basis there had been in most cases established strong monarchies, Europe was broken up into disconnected bodies, and the cherished scheme of a united Christian state appeared less likely than ever to be realized. Nor was this all. Sometimes through race-hatred, more often by the jealousy and ambition of their sovereigns, these countries were constantly involved in war with one another, violating on a larger scale and with more destructive results than in time past the peace of the religious community; while each of them was at the same time torn within by frequent insurrections, and desolated by long and bloody civil wars. The new nationalities were too fully formed to allow the hope that by their extinction a remedy might be applied to these evils. They had grown up in spite of the Empire and the Church, and were not likely to yield in their strength what they had won in their weakness. But it still appeared possible to soften, if not to overcome, their antagonism. What might not be looked for from the erection of a presiding power common to all Europe, a power which, while it should oversee the internal concerns of each country, not dethroning the king, but treating him as an hereditary viceroy, should be more especially charged to prevent strife between kingdoms, and to maintain the public order of Europe by being not only the fountain of international law, but also the judge in its causes and the enforcer of its sentences?

The Popes as international Judges.

To such a position had the Popes aspired. They were indeed excellently fitted for it by the respect which the sacredness of their office commanded; by their control of the tremendous weapons of excommunication and interdict; above all, by their exemption from those narrowing influences of place, or blood, or personal interest, which it would be their chiefest duty to resist in others. And there had been pontiffs whose fearlessness and justice were worthy of their exalted office, and whose interference was gratefully remembered by those who found no other helpers. Nevertheless, judging the Papacy by its conduct as a whole, it had been tried and found wanting. Even when its throne stood firmest and its purposes were most pure, one motive had always biassed its decisions—a partiality to the most submissive. During the greater part of the fourteenth century it was at Avignon the willing tool of France: in the pursuit of a temporal principality it had mingled in and been contaminated by the unhallowed politics of Italy; its supreme council, the college of cardinals, was distracted by the intrigues of two bitterly hostile factions. And while the power of the Popes had declined steadily, though silently, since the days of Boniface the Eighth, the insolence of the great prelates and the vices of the inferior clergy had provoked throughout Western Christendom a reaction against the pretensions of all sacerdotal authority. As there is no theory at first sight more attractive than that which entrusts all government to a supreme spiritual power, which, knowing what is best for man, shall lead him to his true good by appealing to the highest principles of his nature, so there is no disappointment more bitter than that of those who find that the holiest office may be polluted by the lusts and passions of its holder; that craft and hypocrisy lead while fanaticism follows; that here too, as in so much else, the corruption of the best is worst. Some such disappointment there was in Europe now, and with it a certain disposition to look with favour on the secular power: a wish to escape from the unhealthy atmosphere of clerical despotism to the rule of positive law, harsher, it might be, yet surely less corrupting. Espousing the cause of the Roman Empire as the chief opponent of priestly claims, this tendency found it, with shrunken territory and diminished resources, fitter in some respects for the office of an international judge and mediator than it had been as a great national power. For though far less widely active, it was losing that local character which was fast gathering round the Papacy. With feudal rights no longer enforcible, and removed, except in his patrimonial lands, from direct contact with the subject, the Emperor was not, as heretofore, conspicuously a German and a feudal king, and occupied an ideal position far less marred by the incongruous accidents of birth and training, of national and dynastic interests.

Duties attributed to the Empire by the developed theory.

To that position three cardinal duties were attached. He who held it must typify spiritual unity, must preserve peace, must be a fountain of that by which alone among imperfect men peace is preserved and restored, law and justice. The first of these three objects was sought not only on religious grounds, but also from that longing for a wider brotherhood of humanity towards which, ever since the barrier between Jew and Gentile, Greek and barbarian, was broken down, the aspirations of the higher minds of the world have been constantly directed. Placed in the midst of Europe, the Emperor was to bind its tribes into one body, reminding them of their common faith, their common blood, their common interest in each other's welfare. And he was therefore above all things, professing indeed to be upon earth the representative of the Prince of Peace, bound to listen to complaints, and to redress the injuries inflicted by sovereigns or people upon each other; to punish offenders against the public order of Christendom; to maintain through the world, looking down as from a serene height upon the schemes and quarrels of meaner potentates, that supreme good without which neither arts nor letters, nor the gentler virtues of life, can rise and flourish. The mediæval Empire was in its essence what the modern despotisms that mimic it profess themselves: the Empire was peace[279]: the oldest and noblest title of its head was 'Imperator pacificus[280].' Divine right of the Emperor. And that he might be the peacemaker, he must be the expounder of justice and the author of its concrete embodiment, positive law; chief legislator and supreme judge of appeal, like his predecessor the compiler of the Corpus Iuris, the one and only source of all legitimate authority. In this sense, as governor and administrator, not as owner, is he, in the words of the jurists, Lord of the world; not that its soil belongs to him in the same sense in which the soil of France or England belongs to their respective kings: he is the steward of Him who has received the heathen for his possession and the uttermost parts of the earth for his inheritance. It is, therefore, by him alone that the idea of pure right, acquired not by force but by legitimate devolution from those whom God himself had set up, is visibly expressed upon earth. To find an external and positive basis for that idea is a problem which it has at all times been more easy to evade than to solve, and one peculiarly distressing to those who could neither explain the phenomena of society by reducing it to its original principles, nor inquire historically how its existing arrangements had grown up. Hence the attempt to represent human government as an emanation from divine: a view from which all the similar but far less logically consistent doctrines of divine right which have prevailed in later times are borrowed. As has been said already, there is not a trace of the notion that the Emperor reigns by an hereditary right of his own or by the will of the people, for such a theory would have seemed to the men of the middle ages an absurd and wicked perversion of the true order. Nor do his powers come to him from those who choose him, but from God, who uses the electoral princes as mere instruments of nomination. Having such an origin, his rights exist irrespective of their actual exercise, and no voluntary abandonment, not even an express grant, can impair them. Boniface the Eighth[281] reminds the king of France, and imperialist lawyers till the seventeenth century repeated the claim, that he, like other princes, is of right and must ever remain subject to the Roman Emperor. And the sovereigns of Europe long continued to address the Emperor in language, and yield to him a precedence, which admitted the inferiority of their own position[282].

There was in this theory nothing that was absurd, though much that was impracticable. The ideas on which it rested are still unapproached in grandeur and simplicity, still as far in advance of the average thought of Europe, and as unlikely to find men or nations fit to apply them, as when they were promulgated five hundred years ago. The practical evil which the establishment of such a universal monarchy was intended to meet, that of wars and hardly less ruinous preparations for war between the states of Europe, remains what it was then. The remedy which mediæval theory proposed has been in some measure applied by the construction and reception of international law; the greater difficulty of erecting a tribunal to arbitrate and decide, with the power of enforcing its decisions, is as far from a solution as ever.
