taught as a part of morality that men were bound by moral obligations to their slaves. No one, after Christianity became ascendant, could ever again have been a stranger to this belief, in theory; nor, after the rise of the Catholic Church, was it ever without persons to stand up for it. Yet to enforce it was the most arduous task which Christianity ever had to perform. For more than a thousand years the Church kept up the contest, with hardly any perceptible success. It was not for want of power over men's minds. Its power was prodigious. It could make kings and nobles resign their most valued possessions to enrich the Church. It could make thousands, in the prime of life and the height of worldly advantages, shut themselves up in convents to work out their salvation by poverty, fasting, and prayer. It could send hundreds of thousands across land and sea, Europe and Asia, to give their lives for the deliverance of the Holy Sepulchre. It could make kings relinquish wives who were the object of their passionate attachment, because the Church declared that they were within the seventh (by our calculation the fourteenth) degree of relationship. All this it did; but it could not make men fight less with one another, nor tyrannize less cruelly over the serfs, and when they were able, over burgesses. It could not make them renounce either of the applications of force; force militant, or force triumphant. This they could never be induced to do until they were themselves in their turn compelled by superior force. Only by the growing power of kings was an end put to fighting except between kings, or competitors for kingship; only by the growth of a wealthy and warlike bourgeoisie in the fortified towns, and of a plebeian infantry which proved more powerful in the field than the undisciplined chivalry, was the insolent tyranny of the nobles over the bourgeoisie and peasantry brought within some bounds. It was persisted in not only until, but long after, the oppressed had obtained a power enabling them often to take conspicuous vengeance; and on the Continent much of it continued to the time of the French Revolution, though in England the earlier and better organization of the democratic classes put an end to it sooner, by establishing equal laws and free national institutions.
