If it were proved to be ever so desirable to effect such a change in the tastes and prejudices of the American people, history does not lend any countenance to the belief that it is possible. Wherever one people has conquered another, the conquerors and their descendants have always asserted for themselves a political superiority for ages; and that political superiority has extended itself into all the relations of social life. This has taken place with such uniformity, as to impress upon the mind the belief that it occurs in obedience to some great law of human nature, which may be expected to baffle all attempts at resistance in the future, as it has done in the past. The testimony of history is, that equality can be the law of national life only when the nation was originally formed from equal elements. But two peoples never met on the same soil, and under the same government, under conditions so widely unequal as the European and the African populations of this country. The Europeans are, to a great extent, the descendants of the most enlightened men of the world, heirs by birth to the highest civilization of the nineteenth century. The Africans, on the contrary, are the known descendants of parents who were taken by force from their own country, and brought hither as merchandise, sold as chattels and beasts of burden to the highest bidder; and have even now no civilization except what they have acquired in this condition of abject slavery; separated, too, from the dominant class, not only by this stigma of slavery, but by complexion and features so marked and peculiar, that a small taint of the blood of the servile class can be detected with unerring certainty. If history decides anything, it is that a system of political equality cannot be formed out of such elements. The experience of the world is against it.
