Another ironic statement that Ruffin makes is that the South is "the most enlightened and civilized portion of the world." This is also clearly not true, as the South was home to some of the most repressive and backward social policies in the world, including slavery and Jim Crow segregation. Ruffin's statement is ironic because it ignores the South's many social problems and instead presents it as a utopia.
Finally, Ruffin states that the South is "the only hope of the world." This is perhaps the most ironic statement of all, as the South was actually one of the main causes of the world's problems at the time. The South's insistence on slavery and its secession from the Union led to the American Civil War, which was one of the deadliest conflicts in history. Ruffin's statement is ironic because it completely ignores the South's negative impact on the world.
Overall, Ruffin's essay is full of irony. His statements about the South's prosperity, enlightenment, and hope are all contradicted by the reality of the South's situation. This irony serves to highlight the South's many problems and its need for change.
