1. That they have no right to social equality or to political sovereignty--that to accord them either, in their present moral condition, would be a curse instead of a blessing. It would in all probability lead to the extermination of the race, and inflict a deep injury both upon the moral and physical condition of the whole country. 2. That every consideration of humanity and prudence requires that, until a better form of subordinate government shall be devised, they must be continued under the system of domestic slavery now in operation. LECTURE X. EMANCIPATION DOCTRINES DISCUSSED. Gradual emancipation, the popular plan--It would operate to collect the slaves into a few States, cut them off from contact with civilization, and reduce them to barbarism--It would make an opening for Northern farmers and their menials to come into those States from which they retired--The modifications which the system of slavery has undergone within late years--A comparison of the menials of the free and of the slave States, and the only plan of emancipation admissible--The gospel the only remedy for the evils of slavery--Paul’s philosophy and practice, 1 Tim. vi. 1-5. Immediate emancipation is the scheme of the abolitionists proper, whilst gradual emancipation is the favorite plan of the anti-slavery party. The ground we should take is this, that no plan of emancipation, either immediate or gradual, is adapted to the present moral condition and relative circumstances of our African population. Nothing of the kind could at this time be attended with good, but only with evil. I limit this discussion to the subject of gradual emancipation, because the reasons by which we invalidate this doctrine will, _a fortiori_, disprove the doctrine of immediate emancipation. It is said that a system of gradual emancipation succeeded well in the Northern States, and that it would succeed equally well in the Southern. But I deny the assumption in each case.
