These facts are open to the observation of all men. They strongly rebuke the restless agitators of the country. They clearly confirm our position that the Africans in America are not, as yet, in the moral condition for freedom. I have proved in a former lecture that political sovereignty is not a natural but an acquired right. The facts here adduced demonstratively prove that they have not yet acquired this right, and that therefore it cannot be justly claimed for them. But more than this--they afford the strongest presumption (and further than the presumption in its favor, I do not design to notice this topic at this time) that the emancipation of the slaves, in their present moral condition, confers no benefit upon them, but is calculated to inflict a deep injury both upon them and upon society. It is a general, and indeed an almost universal opinion in the South, that any thing like a system of emancipation, whether direct or gradual, by which the number of free colored persons should be materially increased in the Southern States, would inevitably be followed by their indiscriminate massacre, as the only means of abating an insufferable nuisance, unless the citizens were to forsake the soil in favor of a barbarous horde. Such an opinion, (I may repeat,) so generally entertained by so large a community of enlightened and virtuous citizens, who are in immediate proximity with the race, and acquainted with their character from early life, taken in connection with the historical facts here enumerated, affording to any mind so clear a proof of the correctness of their opinion, should be admitted as an authoritative settlement of the position I have taken on this branch of the subject. Hence, we may conclude that the law of reciprocity and the law of benevolence require that the Africans be continued under an inferior and subordinate government. The question again recurs, What form of government shall this be? Of course, it must be a modification of a military despotism, or a modification of the patriarchal form of government. I am free to say that I can conceive of none so appropriate as that adopted by civilization, for the purpose of controlling a barbarous or semi-barbarous race (and especially such as could not amalgamate) dwelling in the midst of a civilized community: that is, the system of domestic government now in operation in the Southern States. If any shall devise another, it will, at least, have the merit of novelty to commend it to public attention.
