Got a link for that quote? I'd like to read it in its entirety. Sounds interesting.
When Southern people tell us that they are no more responsible for the origin of slavery than we are, I acknowledge the fact. When it is said the institution exists, and it is very difficult to get rid of in any satisfactory way, I can understand and appreciate the saying. I surely will not blame them for not doing what I should not know what to do as to the existing institution. My first impulse would possibly be to free all slaves and send them to Liberia to their own native land. But a moment's reflection would convince me that this would not be best for them. If they were all landed there in a day they would all perish in the next ten days, and there is not surplus money enough to carry them there in many times ten days. What then? Free them all and keep them among us as underlings. Is it quite certain that this would alter their conditions? Free them and make them politically and socially our equals? My own feelings will not admit of this, and if mine would, we well know that those of the great mass of whites will not. We cannot make them our equals. A system of gradual emancipation might well be adopted, and I will not undertake to judge our Southern friends for tardiness in this matter."
