It was our misfortune, and in some sense it was also our fault, that we were bound to uphold the worst system of slavery that ever was known among men; for we must judge of every wrong that is perpetrated by the circumstances that are connected with it, and our oppression of the African race was peculiarly offensive, inasmuch as it was a proceeding in flagrant violation of our constantly avowed principles, was continued in face of the opinions of the founders of the nation, was frankly upheld on the unmanly ground that the intellectual weakness of the slaves rendered it safe to oppress them, and was not excused by that general ignorance of right which has so often been brought forward in palliation of wrong,—­as slavery had come under the ban of Christendom years before Americans could be found boldly bad enough to claim for it a divine origin, and to avow that it was a proper, and even the best, foundation for civil society.  Our offence was of the rankest, and its peculiar character rendered us odious in the eyes of the nations, who would not admit the force of our plea as to the great difficulties that lay in the way of the removal of the evil, as they had seen it condemned by most communities, and abolished by some of their number.

The very circumstance upon which Americans have relied for the justification of their form of slavery, namely, that it was confined to one race, and that race widely separated from all other races by the existence of peculiar characteristics, has been regarded as an aggravation of their misconduct by all humane and disinterested persons.  The Greek system of slavery, which was based on the idea that Greeks were noblemen of Heaven’s own creating, and that they therefore were justified in treating all other men as inferiors, and making the same use of them as they made of horses; the Roman system, which was based on the will of society, and therefore made no exceptions on the score of color, but saw in all strangers only creatures of chase; the Mussulman system, brought out so strongly by the action of the States of Barbary, and which was colored by the character of the long quarrel between Mahometans and Christians, and under which Northern Africa was filled with myriads of slaves from Southern Europe, among whom were men of the highest intellect,—­Cervantes, for example;—­all these systems of servitude, and others that might be adduced, were respectable in comparison with our system, which proceeded upon the blasphemous assumption that God had created and set apart one race that should forever dwell in the house of bondage.  If, in some respects, our system has been more humane than that of other peoples in other times, the fact is owing to that general improvement which has taken place the earth over during the present century.  The world has gone forward, and even American slaveholders have been compelled to go with it, whether they would or not.
