By exclusive attention to one class of phenomena, by exclusive taste for one species of excellence the human intellect was stunted. The best historians of later days have been seduced from truth, not by their imagination, but by their reason. They far excel their predecessors in the art of deducing general principles from facts, but unhappily they have fallen into the error of distorting the facts to suit the general principles. They arrive at a theory from looking at a part of the phenomena; the remaining phenomena they strain or curtail to suit the theory. In every human character and transaction there is a mixture of good and evil: a little exaggeration, a little suppression, a judicious use of epithets, a watching and searching skepticism with respect to the evidence on one side, a convenient credulity with respect to every report or tradition on the other side may easily make a saint of Laud or a tyrant of Henry IV. The Negro's most important contribution to American history is his unparalleled progress--his rise from poverty to wealth, from ignorance to knowledge, from backwardness to civilization. No other race has achieved more under the same conditions. No authentic history of the United States, then, can ignore or exclude the Negro. The part which he has played in American history has served largely to make the nation what it is today. The fidelity of the Negro slave to his master, his devotion and loyalty to his country should constitute interesting historical themes. Under the regime of slavery the Negro was literally bought and sold like the very soil. His life was but one unceasing round of toil and misery; his faith, his hope, and his ambition, were fettered down with chains which he had no power to rend. Under these circumstances he contributed two hundred and fifty years of unrequited toil. With the muscles of his brawny arms he cleared away the forests, tilled the soil, and made the wilderness to blossom like the rose. With his callous hands he has built railroads and cities in this country and has thus made this a goodly land in which to live.
