As we cannot suppose the agitators of the country on this subject to be ignorant of the fact that such is the opinion of the Southern people, and as we cannot allow that they are incapable of appreciating the weight of this testimony, we reach the conclusion that they are the victims of a fanaticism resulting from a mistaken religious opinion and feeling, which hurries them madly forward, as regardless of the extent to which they implicate their own good sense as they are of the extent to which they are aspersing the reputation of their fellow-citizens, or the degree to which they are actually putting to hazard the lives of the very people for whom they piously persuade themselves they are laboring. Those whose conduct does not admit of this apology are generally men who occupy the arena of political agitation. Their object, evidently, is to accumulate political power in the so-called free States, and to promote the ends of personal ambition. The fanatical excitement of the country may be turned to the account of these objects. Hence, they labor with a zeal worthy of a better cause. We of the South regard the agitators in Congress, for the most part, to be of this class. We consider them highly culpable, if, indeed, they be not actually criminal. For we cannot suppose them to be ignorant of the facts and reasonings here adduced. And besides these, there are other facts of great and conclusive authority in the settlement of this question, which we cannot suppose have escaped the attention of men occupying their high stations. I propose to notice some of them in the next lecture. LECTURE IX. THE NECESSITY FOR THE INSTITUTION OF DOMESTIC SLAVERY EXEMPLIFIED BY FACTS. The attempts made at domestic colonization--The result of the experiment in the case of our free colored population--The colonization experiment on the coast of Africa--The example of the Canaanitish nations--Summary of the argument on the general point, and inferences. “That the Africans are not, in point of intellectual and moral development, fitted for that measure of self-government which is necessary to political sovereignty: that political equality cannot be justly claimed for them--they have no right to it: that to them it could not be an essential good, but an essential evil, a curse; and that to confer it on them, by an act of direct or gradual emancipation, would be eminently productive of injury to the whole country, and utterly ruinous to them.” This is the general proposition still under consideration. We have already discussed to some extent the first two points. I reserve the subject of emancipation for future lectures. I now proceed to exemplify the truth of the positions discussed on this general proposition, and thereby show the actual necessity that we sustain, in the present circumstances of the race, the system of domestic slavery. And, First. We adduce the fact of domestic colonization.
