Color in the animal kingdom is according to the Law of Nature. The ox of the Roman Campagna is gray. The herds on the banks of the Xanthus were yellow; on the banks of the Clitumnus they were white. In Corsica animals are spotted. The various colors of the human family belong to the same mystery. There are white, yellow, red, and black, with intermediate shades; but no matter what their hue, they are always MEN, gifted with a common manhood and entitled to common rights. Dr. Johnson made short work with the famous paradox of Berkeley, denying the existence of matter. Striking his foot with mighty force against a large stone, till he rebounded from it, “I refute it _thus_,” he exclaimed.[205] And so, in reply to every pretension against the equal rights of all, to every assertion of right founded on the skin, to every denial of right because a man is something else than white, I point to that common manhood which knows no distinction of color, and thus do I refute the whole inhuman, unchristian paradox. THE WORD “WHITE.” Observe, if you please, how little the word “white” is authorized to play the great part it performs, and how much of an intruder it is in all its appearances. In those two title-deeds, the Declaration of Independence and the Constitution, there are no words of color, whether white, yellow, red, or black; but here is the fountain out of which all is derived. The Declaration speaks of “all men,” and not of “all _white_ men”; and the Constitution says, “We the people,” and not “We the _white_ people.” Where, then, is authority for any such discrimination, whether by the nation or any component part? There is no fountain or word for it. The fountain failing, and the word non-existent, the whole pretension is a disgusting usurpation, which is more utterly irrational when it is considered that authority for such an outrage can be found only in positive words, plain and unambiguous in meaning. This was the rule with regard to Slavery, solemnly declared by Lord Mansfield in the famous Somerset case; and it must be the same with regard to this pretension. It cannot be invented, imagined, or implied; it must be found in the very text: and this I assert according to fixed principles of jurisprudence. In its absence, Equality is “the supreme law of the land; and the judges in every State shall be bound thereby, anything in the constitution or laws of any State to the contrary notwithstanding.”[206] This conclusion is reinforced by the several Constitutional Amendments; but I prefer to dwell on the original text of the Constitution, in presence of which you might as well undertake to make a king as to degrade a fellow-citizen on account of his skin.
