And comparing what happened in England—after all, in England the Parliament in Westminster was making laws for the West Indies. The West Indians didn't have any representation in the Parliament. The laws were made for them, and they had to go along with it. There was no such power within the Federal government to interfere with slavery, except by limiting the expansion of slavery. And it was Lincoln’s belief—and I think the best economic analysis that we have of the American economy in the antebellum United States indicates—that if the expansion of slavery had been ended, and if it was no longer possible for surplus slaves to be sold from the old states to new territories, that the pressure within the states to adopt programs of emancipation would become great enough to do that.
