But if the objection I am combating be modified and restricted to the influence of that usage which denies them social freedom, I will agree that it has weight. It certainly retards the progress of those who are rising to the moral condition of freedom: hangs like an incubus upon those who have already risen to that state, and effectually shuts the door of enjoyment against them. This is no doubt true. But why are they denied social freedom? The answer is, Because they cannot amalgamate by a spontaneous intermarriage with the whites. But this is a disability under which God, by the nature of their physical constitution, has placed them, and which the progress of civilization itself forbids the whites to disregard. Therefore it is obvious that they never can be free in a community of whites. Because, as there is no essential freedom, but that which is inseparable from social as well as political freedom, and as there can be no social freedom, but that which coincides with the law of amalgamation by intermarriage; and as Divine Providence has closed the door against this, it follows that the African never can be free in the midst of a community of whites. But still, that this is not the primary and essential cause of the extreme degradation of those Africans upon whom the experiment of freedom has been tried in this country and found to be a failure, and that it is originally traceable to the fact that they are not, intellectually and morally, prepared for self-government, is still more clearly deducible from a Third consideration--the colonization experiment on the coast of Africa. The colony of Liberia has already taken its place among the nations of the earth as a free and independent government. No colony has ever prospered as that has done. As a rising nation, it shares the sympathy of the civilized world. It is destined to become the asylum of the Africans of America, and the centre of civilization to the long-benighted continent of Africa. Thither all eyes are turned as the oasis of hope in her desert history.
