This attempt to usurp the government by subverting the Constitution of the United States was the policy of the greatest leader the system of slavery has ever had in this country - that pagan of our politics, Mr. Calhoun. While other statesmen merely saw, he foresaw. His mind, of large forecast and comprehensive grasp, perceived that the logic of history, of civilization, of our national idea, of the universal conscience, was against slavery. But he had seen the conscience of the country, roused for a moment in the Missouri debate, drop asleep again. And with the audacity of genius he resolved to stun the country into acquiescence by claiming that slavery was the fundamental law of the land.
