The men of the Revolution passed away; a new generation sprang up, impatient that an institution to which they clung should be condemned as inhuman, unwise, and unjust. In the throes of discontent at the self-reproach of their fathers, and blinded by the lustre of wealth to be acquired by the culture of a new staple, they devised the theory that slavery, which they would not abolish, was not evil, but good. They turned on the friends of colonization, and confidently demanded: "Why take black men from a civilized and Christian country, where their labor is a source of immense gain, and a power to control the markets of the world, and send them to a land of ignorance, idolatry, and indolence, which was the home of their forefathers, but not theirs? Slavery is a blessing. Were they not in their ancestral land naked, scarcely lifted above brutes, ignorant of the course of the sun, controlled by nature? And in their new abode have they not been taught to know the difference of the seasons, to plough, and plant, and reap, to drive oxen, to tame the horse, to exchange their scanty dialect for the richest of all the languages among men, and the stupid adoration of follies for the purest religion? And since slavery is good for the blacks, it is good for their masters, bringing opulence and the opportunity of educating a race. The slavery of the black is good in itself; he shall serve the white man forever." And nature, which better understood the quality of fleeting interest and passion, laughed as it caught the echo, "man" and "forever!" A regular development of pretensions followed the new declaration with logical consistency. Under the old declaration every one of the States had retained, each for itself, the right of manumitting all slaves by an ordinary act of legislation; now the power of the people over servitude through their legislatures was curtailed, and the privileged class was swift in imposing legal and constitutional obstructions on the people themselves. The power of emancipation was narrowed or taken away. The slave might not be disquieted by education. There remained an unconfessed consciousness that the system of bondage was wrong, and a restless memory that it was at variance with the true American tradition; its safety was therefore to be secured by political organization. The generation that made the Constitution took care for the predominance of freedom in Congress by the ordinance of Jefferson; the new school aspired to secure for slavery an equality of votes in the Senate, and, while it hinted at an organic act that should concede to the collective South a veto power on national legislation, it assumed that each State separately had the right to revise and nullify laws of the United States, according to the discretion of its judgment.
