How we cite our quotes: (Paragraph)
Quote #1
Did we pledge ourselves to the support of an airy nothing—a bubble that must be blown away by the first breath of disaffection? [...] No. We were not mistaken. (16)
Jackson wants to be clear: rules are meant to be followed. Without rules, there is no order, no Constitution, and no America. The Union is a robust thing; we love the metaphor, "airy nothing—a bubble." Wonder who actually wrote the Proclamation.
Quote #2
[I want to] to warn the citizens of South Carolina, who have been deluded into an opposition to the laws, of the danger they will incur by obedience to the illegal and disorganizing ordinance of the convention—to exhort those who have refused to support it to persevere in their determination to uphold the Constitution and laws of their country, and to point out to all the perilous situation into which the good people of that State have been led, and that the course they are urged to pursue is one of ruin and disgrace to the very State whose rights they affect to support. (35)
Since the convention was clear in its support for nullification, all Jackson can do is to appeal to the people who might have buyer's remorse. He implies they've been fooled by their leaders into a situation that's going to devolve into total lawlessness, and they'll all look like fools for going along with it. "Disorganization" is the key word here.
Quote #3
Are you really ready to incur its guilt? If you are, on the head of the instigators of the act be the dreadful consequences—on their heads be the dishonor, but on yours may fall the punishment—on your unhappy State will inevitably fall all the evils of the conflict you force upon the government of your country. (37)
Here's another "power to the people" appeal. They're the ones who will suffer the consequences, even if the leaders are the ones who instigated it. It's a divide and conquer strategy. Jackson always had faith in the people to do the right thing.
