"Chief Justice does not directly assert, but plainly assumes, as a fact, that the public estimate of the black man is more favorable now than it was in the days of the Revolution. This assumption is a mistake... In those days, as I understand, masters could, at their own pleasure, emancipate their slaves; but since then, such legal restraints have been made upon emancipation, as to amount almost to prohibition. In those days, Legislatures held the unquestioned power to abolish slavery in their respective States; but now it is becoming quite fashionable for State Constitutions to withhold that power from the Legislatures. In those days, by common consent, the spread of the black man's bondage to new countries was prohibited; but now, Congress decides that it will not continue the prohibition, and the Supreme Court decides that it could not if it would. In those days, our Declaration of Independence was held sacred by all, and thought to include all; but now, to aid in making the bondage of the negro universal and eternal, it is assailed, and sneered at, and construed, and hawked at, and torn, till, if its framers could rise from their graves, they could not at all recognize it... The Declaration of Independence includes ALL men, black as well as white, and forth... I appeal to all, to Democrats as well as others, are you really willing that the Declaration shall be thus frittered away? Thus left no more at most, than an interesting memorial of the dead past? Thus shorn of its vitality, and practical value; and left without the germ or even the suggestion of the individual rights of man in it?"
