In later versions of Common Sense, Paine adds responses to a speech by King George III, which he calls a piece of villainy. In the appendix, he reiterates arguments against the claim that America is not ready for independence, asserting that the United States now has enough military experience to fight for independence and that delaying the effort will only make it harder. He warns that the longer it takes, the more likely it is that a mob mentality will take hold, preventing America from forming a good constitution.
