"Parchment and paper, printing and engraving, improved glass and steel, gunpowder, clocks, telescopes, the mariner's compass, the reformed calendar, the decimal notation; algebra, trigonometry, chemistry, counterpoint (an invention equivalent to a new creation of music); these are all possessions which we inherit from that which has so disparagingly been termed the Stationary Period" (History of Inductive Sciences, i. 252).

True that no new principle was illustrated by any of these discoveries, as Whewell said; but medieval science had done something more than the actual discovery of new principles. It had prepared the discovery of all the new principles which we know at the present time in mechanical sciences: it had accustomed the explorer to observe facts and to reason from them. It was inductive science, even though it had not yet fully grasped the importance and the powers of induction; and it laid the foundations of both mechanics and natural philosophy. Francis Bacon, Galileo, and Copernicus were the direct descendants of a Roger Bacon and a Michael Scot, as the steam engine was a direct product of the researches carried on in the Italian universities on the weight of the atmosphere, and of the mathematical and technical learning which characterized Nuremberg.

But why should one take trouble to insist upon the advance of science and art in the medieval city? Is it not enough to point to the cathedrals in the domain of skill, and to the Italian language and the poem of Dante in the domain of thought, to give at once the measure of what the medieval city created during the four centuries it lived?

The medieval cities have undoubtedly rendered an immense service to European civilization. They have prevented it from being drifted into the theocracies and despotical states of old; they have endowed it with the variety, the self-reliance, the force of initiative, and the immense intellectual and material energies it now possesses, which are the best pledge for its being able to resist any new invasion of the East. But why did these centres of civilization, which attempted to answer to deeply-seated needs of human nature, and were so full of life, not live further on? Why were they seized with senile debility in the sixteenth century? and, after having repulsed so many assaults from without, and only borrowed new vigour from their interior struggles, why did they finally succumb to both?

Various causes contributed to this effect, some of them having their roots in the remote past, while others originated in the mistakes committed by the cities themselves. Towards the end of the fifteenth century, mighty States, reconstructed on the old Roman pattern, were already coming into existence. In each country and each region some feudal lord, more cunning, more given to hoarding, and often less scrupulous than his neighbours, had succeeded in appropriating to himself richer personal domains, more peasants on his lands, more knights in his following, more treasures in his chest. He had chosen for his seat a group of happily-situated villages, not yet trained into free municipal life—Paris, Madrid, or Moscow—and with the labour of his serfs he had made of them royal fortified cities, whereto he attracted war companions by a free distribution of villages, and merchants by the protection he offered to trade. The germ of a future State, which began gradually to absorb other similar centres, was thus laid. Lawyers, versed in the study of Roman law, flocked into such centres; a tenacious and ambitious race of men issued from among the burgesses, who equally hated the naughtiness of the lords and what they called the lawlessness of the peasants. The very forms of the village community, unknown to their code, the very principles of federalism were repulsive to them as "barbarian" inheritances. Caesarism, supported by the fiction of popular consent and by the force of arms, was their ideal, and they worked hard for those who promised to realize it.(37)

The Christian Church, once a rebel against Roman law and now its ally, worked in the same direction. The attempt at constituting the theocratic Empire of Europe having proved a failure, the more intelligent and ambitious bishops now yielded support to those whom they reckoned upon for reconstituting the power of the Kings of Israel or of the Emperors of Constantinople. The Church bestowed upon the rising rulers her sanctity, she crowned them as God's representatives on earth, she brought to their service the learning and the statesmanship of her ministers, her blessings and maledictions, her riches, and the sympathies she had retained among the poor. The peasants, whom the cities had failed or refused to free, on seeing the burghers impotent to put an end to the interminable wars between the knights—which wars they had so dearly to pay for—now set their hopes upon the King, the Emperor, or the Great Prince; and while aiding them to crush down the mighty feudal owners, they aided them to constitute the centralized State. And finally, the invasions of the Mongols and the Turks, the holy war against the Maures in Spain, as well as the terrible wars which soon broke out between the growing centres of sovereignty—Ile de France and Burgundy, Scotland and England, England and France, Lithuania and Poland, Moscow and Tver, and so on—contributed to the same end. Mighty States made their appearance; and the cities had now to resist not only loose federations of lords, but strongly-organized centres, which had armies of serfs at their disposal.

The worst was, that the growing autocracies found support in the divisions which had grown within the cities themselves. The fundamental idea of the medieval city was grand, but it was not wide enough. Mutual aid and support cannot be limited to a small association; they must spread to its surroundings, or else the surroundings will absorb the association. And in this respect the medieval citizen had committed a formidable mistake at the outset. Instead of looking upon the peasants and artisans who gathered under the protection of his walls as upon so many aids who would contribute their part to the making of the city—as they really did—a sharp division was traced between the "families" of old burghers and the newcomers. For the former, all benefits from communal trade and communal lands were reserved, and nothing was left for the latter but the right of freely using the skill of their own hands. The city thus became divided into "the burghers" or "the commonalty," and "the inhabitants."(38) The trade, which was formerly communal, now became the privilege of the merchant and artisan "families," and the next step—that of becoming individual, or the privilege of oppressive trusts—was unavoidable.

The same division took place between the city proper and the surrounding villages. The commune had well tried to free the peasants, but her wars against the lords became, as already mentioned, wars for freeing the city itself from the lords, rather than for freeing the peasants. She left to the lord his rights over the villeins, on condition that he would molest the city no more and would become co-burgher. But the nobles "adopted" by the city, and now residing within its walls, simply carried on the old war within the very precincts of the city. They disliked to submit to a tribunal of simple artisans and merchants, and fought their old feuds in the streets. Each city had now its Colonnas and Orsinis, its Overstolzes and Wises. Drawing large incomes from the estates they had still retained, they surrounded themselves with numerous clients and feudalized the customs and habits of the city itself. And when discontent began to be felt in the artisan classes of the town, they offered their sword and their followers to settle the differences by a free fight, instead of letting the discontent find out the channels which it did not fail to secure itself in olden times.

The greatest and the most fatal error of most cities was to base their wealth upon commerce and industry, to the neglect of agriculture. They thus repeated the error which had once been committed by the cities of antique Greece, and they fell through it into the same crimes.(39) The estrangement of so many cities from the land necessarily drew them into a policy hostile to the land, which became more and more evident in the times of Edward the Third,(40) the French Jacqueries, the Hussite wars, and the Peasant War in Germany. On the other hand, a commercial policy involved them in distant enterprises. Colonies were founded by the Italians in the south-east, by German cities in the east, by Slavonian cities in the far northeast. Mercenary armies began to be kept for colonial wars, and soon for local defence as well. Loans were contacted to such an extent as to totally demoralize the citizens; and internal contests grew worse and worse at each election, during which the colonial politics in the interest of a few families was at stake. The division into rich and poor grew deeper, and in the sixteenth century, in each city, the royal authority found ready allies and support among the poor.

And there is yet another cause of the decay of communal institutions, which stands higher and lies deeper than all the above. The history of the medieval cities offers one of the most striking illustrations of the power of ideas and principles upon the destinies of mankind, and of the quite opposed results which are obtained when a deep modification of leading ideas has taken place. Self-reliance and federalism, the sovereignty of each group, and the construction of the political body from the simple to the composite, were the leading ideas in the eleventh century. But since that time the conceptions had entirely changed. The students of Roman law and the prelates of the Church, closely bound together since the time of Innocent the Third, had succeeded in paralyzing the idea—the antique Greek idea—which presided at the foundation of the cities. For two or three hundred years they taught from the pulpit, the University chair, and the judges' bench, that salvation must be sought for in a strongly-centralized State, placed under a semi-divine authority;(41) that one man can and must be the saviour of society, and that in the name of public salvation he can commit any violence: burn men and women at the stake, make them perish under indescribable tortures, plunge whole provinces into the most abject misery. Nor did they fail to give object lessons to this effect on a grand scale, and with an unheard-of cruelty, wherever the king's sword and the Church's fire, or both at once, could reach. By these teachings and examples, continually repeated and enforced upon public attention, the very minds of the citizens had been shaped into a new mould. They began to find no authority too extensive, no killing by degrees too cruel, once it was "for public safety." And, with this new direction of mind and this new belief in one man's power, the old federalist principle faded away, and the very creative genius of the masses died out. The Roman idea was victorious, and in such circumstances the centralized State had in the cities a ready prey.
