Slavery within the States of the Union stood sufficiently protected by every solemn sanction the Constitution could afford. No man could touch it there, think, or hope, or purpose what he might. But where new States were to be made it was not so. There at every step choice must be made: slavery or no slavery?--a new choice for every new State: a fresh act of origination to go with every fresh act of organization. Had there been no Territories, there could have been no slavery question, except by revolution and contempt of fundamental law. But with a continent to be peopled, the choice thrust itself insistently forward at every step and upon every hand. This was the slavery question: not what should be done to reverse the past, but what should be done to redeem the future. It was so men of that day saw it,--and so also must historians see it. We must not mistake the programme of the Anti-Slavery Society for the platform of the Republican party, or forget that the very war itself was begun ere any purpose of abolition took shape amongst those who were statesmen and in authority. It was a question, not of freeing men, but of preserving a Free Soil. Kansas showed us what the problem was, not South Carolina: and it was the Supreme Court, not the slave-owners, who formulated the matter for our thought and purpose. And so, upon every hand and throughout every national question, was the commerce between East and West made up: that commerce and exchange of ideas, inclinations, purposes, and principles which has constituted the moving force of our life as a nation. Men illustrate the operation of these singular forces better than questions can: and no man illustrates it better than Abraham Lincoln. “Great captains with their guns and drums Disturb our judgment for the hour; But at last silence comes: These all are gone, and, standing like a tower, Our children shall behold his fame, The kindly-earnest, brave, foreseeing man, Sagacious, patient, dreading praise not blame, New birth of our new soil, the first American.”
