Final answer:
Calhoun defended slavery by arguing that it prevented labor conflicts in the South and provided stability and economic benefits, contrasting it with the North's wage system that was seen as more exploitative. He portrayed slavery as a positive good essential for the peace and economic stability of Southern society.
Step-by-step explanation:
John C. Calhoun's justification of slavery revolves primarily around the idea that it was a stabilizing force that prevented class conflict and economic instability in the South. He believed that slavery exempted the South from the labor and capital conflicts that plagued the North, leading to a more stable and tranquil society. Additionally, Calhoun and other southern defenders of slavery thought that slavery was a positive good that provided order and benefits to both the enslaved and the enslavers, contrasting it with the North's wage labor system which was seen as exploitative.
Calhoun's arguments for slavery included the notion that it offered a peaceful coexistence between races and classes, provided basic needs for the enslaved, and supported an economy that allowed white Southerners to pursue what they saw as higher civilization endeavors. This was part of a broader southern ideology that depicted slavery as not only an economic necessity but also as a moral and stabilizing institution.
