Of the great family of man, the negro has, during the last half century, been more prominently before the world than any other race. He did not seek this notoriety. Isolated away in his own land, he would have remained there, had it not been for the avarice of other races, who sought him out as a victim of slavery. Two and a half centuries of the negro's enslavement have created, in many minds, the opinion that he is intellectually inferior to the rest of mankind; and now that the blacks seem in a fair way to get their freedom in this country, it has been asserted, and from high authority in the government, that the natural inferiority of the negro makes it impossible for him to live on this continent with the white man, unless in a state of bondage. In his interview with a committee of the colored citizens of the District of Columbia, on the 14th of August last, the President of the United States intimated that the whites and the blacks could not live together in peace, on account of one race being superior intellectually to the other. Mr. Postmaster General Blair, in his letter to the Union mass meeting held at the Cooper Institute, in New York, in March last, takes this ground. The Boston "Post" and "Courier" both take the same position. I admit that the condition of my race, whether considered in a mental, moral, or intellectual point of view, at the present time cannot compare favorably with the Anglo-Saxon. But it does not become the whites to point the finger of scorn at the blacks, when they have so long been degrading them. The negro has not always been considered the inferior race. The time was when he stood at the head of science and literature. Let us see. It is the generally received opinion of the most eminent historians and ethnologists, that the Ethiopians were really negroes, although in them the physical characteristics of the race were exhibited in a less marked manner than in those dwelling on the coast of Guinea, from whence the stock of American slaves has been chiefly derived. That, in the earliest periods of history, the Ethiopians had attained a high degree of civilization, there is every reason to believe; and that to the learning and science derived from them we must ascribe those wonderful monuments which still exist to attest the power and skill of the ancient Egyptians.
