Ergo, it is Just

The total abolitionists appear to consider the political expediency of liberating the slaves as a secondary or minor consideration, and contend principally for the abstract justice of such a measure. We are willing to concede to them that all of GOD’S creatures have a natural right to liberty, and that the natural inferiority of the negro which we expect to prove, (but what our oponents do not admit,) does not justify the white man in an assumption of unjust power. But when it is shown that the negro and his master, together with the noisy bigots of the north, are all benefited by the present condition of the slaves, then it is undeniably expedient in every view of the case;—ergo, it is Just.
~ Richard H. Colfax (1833)
