Slavery, by separating the mass of the ignorant from each other, and bringing them in contact and daily intercourse with the well-informed, becomes an admirable educational system--no doubt a necessary one. By subjecting them to the constant control and supervision of their superiors, interested in enforcing morality, it becomes the best and most efficient police system; so efficient, that the ancient Romans had scarcely any criminal code whatever.
The great objections to the colonial slavery of the latter Romans, to serfdom, and all forms of prædial slavery, are: that the slaves are subjected to the cares as well as the labors of life; that the masters become idlers; that want of intercourse destroys the affectionate relations between master and slave, throws the mass of ignorant slaves into no other association but that with the ignorant; and deprives them, as well of the instruction, as the government, of superiors living on the same farm. Southern slavery is becoming the best form of slavery of which we have any history, except that of the Jews. The Jews owned but few slaves, and with them the relation of master and slave was truly affectionate, protective and patriarchal. The master, wife and children were in constant intercourse with the slaves, and formed, in practice as well as theory, affectionate, well-ordered families.
As modern civilization advances, slavery becomes daily more necessary, because its tendency is to accumulate all capital in a few hands, cuts off the masses from the soil, lessens their wages and their chances of employment, and increases the necessity for a means of certain subsistence, which slavery alone can furnish, when a few own all the lands and other capital.
Christian morality can find little practical foothold in a community so constituted, that to "love our neighbor as ourself," or "to do unto others as we would they should do unto us," would be acts of suicidal self-sacrifice. Christian morality, however, was not preached to free competitive society, but to slave society, where it is neither very difficult nor unnatural to practice it. In the various family relations of husband, wife, parent, child, master and slave, the observance of these Christian precepts is often practiced, and almost always promotes the temporal well being of those who observe it. The interests of the various members of the family circle, correctly understood, concur and harmonize, and each member best promotes his own selfish interest by ministering to the wants and interests of the rest. Two great stumbling blocks are removed from the acceptance of Scripture, when it is proved that slavery, which it recognizes, approves and enjoins, is promotive of men's happiness and well-being, and that the morality, which it inculcates, although wholly impracticable in free society, is readily practised in that form of society to which it was addressed.
