The author has heretofore signified a willingness to admit the lawfulness of slavery, when induced by “crime or captivity;” but now denies the validity of such admission, because the relations of “crime and captivity” can never be proved. The apparent object of his admission was merely to rally us, by his liberality, to the admission that these relations could never be proved; and we admit they never can be in the way he provides; and he therefore announces the demonstration of the proposition, that slavery can never be just, because “these relations,” which alone make it so, can never be established. But what are the reasons? They are the very causes which render the Africans obnoxious to the condition of slavery—the degraded, deteriorated, and savage state of that people. The negro slave, in his transit from the interior of Africa, is often sold many times, by one master and chieftain to another, before he reaches the western coast, whence he was transferred by the slave factors to the English colonies. No memory of these facts, or of the slave’s origin, is preserved or attempted. Under these circumstances, though each individual of these slaves induced the condition by “crime or captivity,” such fact could never be established in the English colony. To attempt proof there of any fact touching the case, would be as idle and futile as to attempt such proof in regard to the biography of a baboon. Besides, the truth is, a very large portion of these slaves were born slaves in Africa, inheriting their condition from a slave ancestry of unknown ages, and recognised to be slaves by the laws and customs of the various tribes there, and sent to market as a surplus commodity, in accordance to the laws and usages among them, enforced from time immemorial. So far as we have knowledge of the various families of man, we believe it to have ever been the practice for one nation to receive the national acts of another as facts fixed, and not subject to further investigation or alteration by a foreign people, especially when none but the people making the decision were affected by it. Johnson surely must have agreed to such a practice, because an opposite course, so far as carried into action, would have involved every nation in universal war and endless bloodshed. Besides, the right to usurp such control would involve the right to enslave, and can only exist when the degeneracy of a nation has become too great a nuisance to be longer tolerated with safety by the people annoyed: self-protection will then warrant the right.
